163 ideas
| 20262 | Don't use wisdom in order to become clever! [Nietzsche] |
| Full Idea: One ought not to use one's wisdom to become clever! | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 308) | |
| A reaction: And I would add 'don't think that being clever makes you wise'. Nietzsche, as always, is subtler than me (which is why I read him a lot). Presumably wisdom is broad, and cleverness is focused. Will becoming clever spoil someone's wisdom? |
| 19648 | Since Kant we think we can only access 'correlations' between thinking and being [Meillassoux] |
| Full Idea: The central notion of philosophy since Kant is 'correlation' - that we only ever have access to the correlation between thinking and being, and never to either term considered apart from the other. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 1) | |
| A reaction: Meillassoux's charge is that philosophy has thereby completely failed to grasp the scientific revolution, which has used mathematics to make objectivity possible. Quine and Putnam would be good examples of what he has in mind. |
| 19674 | The Copernican Revolution decentres the Earth, but also decentres thinking from reality [Meillassoux] |
| Full Idea: The Copernican Revolution is not so much the decentring of observers in the solar system, but (by the mathematizing of nature) the decentring of thought relative to the world within the process of knowledge. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 5) | |
| A reaction: In other words, I take it, the Copernican Revolution was the discovery of objectivity. That is a very nice addition to my History of Ideas collection. |
| 19657 | In Kant the thing-in-itself is unknowable, but for us it has become unthinkable [Meillassoux] |
| Full Idea: The major shift that has occurred in the conception of thought from Kant's time to ours is from the unknowability of the thing-in-itself to its unthinkability. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 2) | |
| A reaction: Meillassoux is making the case that philosophy is alienating us more and more from the triumphant realism of the scientific revolution. He says thinking has split from being. He's right. Modern American pragmatists are the worst (not Peirce!). |
| 20255 | Early 19th century German philosophers enjoyed concepts, rather than scientific explanations [Nietzsche] |
| Full Idea: Early 19th century German philosophers retreated to the first and oldest level of speculation, for, like the thinkers of dreamy ages, they found satisfaction in concepts rather than in explanations - they resuscitated a prescientific type of philosophy. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 197) | |
| A reaction: I have a suspicion that this may still apply to 'continental philosophy'. Personally I love explanations, which lead to understanding. But not all explanations are scientific. |
| 20260 | Carlyle spent his life vainly trying to make reason appear romantic [Nietzsche] |
| Full Idea: Thomas Carlyle spent a long life trying to make reason romantic to his fellow Englishmen: to no avail! | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 298) | |
| A reaction: An interesting gloss on the shift from the Enlightenment to the Romantic era. Presumably the idea of the 'genius' and the 'hero' are the means whereby Carlyle hoped to achive this. |
| 20256 | What we think is totally dictated by the language available to express it [Nietzsche] |
| Full Idea: We have at every moment only that very thought for which we have ready to hand the words that are roughly capable of expressing it. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 257) | |
| A reaction: This is a highly influential idea, even if this expression of it is little known. Everyone who places language at the centre of philosophy believes something like this. It is a very striking thought, and must certainly contain considerable truth. |
| 16395 | Kripke separated semantics from metaphysics, rather than linking them, making the latter independent [Kripke, by Stalnaker] |
| Full Idea: Kripke's contribution was not to connect metaphysical and semantic issues, but to separate them: to provide a context in which questions about essences of things could be posed independently of assumptions about semantic rules of reference. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Robert C. Stalnaker - Reference and Necessity Intro | |
| A reaction: In other words, Kripke set metaphysics free from the tyranny of Quine, and facilitated its modern rebirth. Bravo. |
| 20265 | The desire for a complete system requires making the weak parts look equal to the rest [Nietzsche] |
| Full Idea: There is playacting going on among systematisers: inasmuch as they want to make the system whole and round off the horizon around it, they must attempt to have their weaker qualities appear in the same style as their strong ones. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 318) | |
| A reaction: Filed under 'rationalism', because they are the notorious system builders, but the same tendency and problem can be seen to some extent among empiricsts who seek completeness. David Lewis, perhaps. |
| 17034 | Analyses of concepts using entirely different terms are very inclined to fail [Kripke] |
| Full Idea: Philosophical analyses of some concept like reference, in completely different terms which make no mention of reference, are very apt to fail. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 2) | |
| A reaction: Kripke consistently criticises analysic, and philosophical 'theories'. It is why he wanted a 'direct' theory of reference, with just you and the object. |
| 19675 | Since Kant, philosophers have claimed to understand science better than scientists do [Meillassoux] |
| Full Idea: Ever since Kant, to think science as a philosopher has been to claim that science harbours a meaning other than the one delivered by science itself. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 5) | |
| A reaction: The point is that science discovered objectivity (via the mathematising of nature), and Kant utterly rejected objectivity, by enmeshing the human mind in every possible scientific claim. This makes Meillassoux and I very cross. |
| 19649 | Since Kant, objectivity is defined not by the object, but by the statement's potential universality [Meillassoux] |
| Full Idea: Since Kant, objectivity is no longer defined with reference to the object in itself, but rather with reference to the possible universality of an objective statement. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 1) | |
| A reaction: Meillassoux disapproves of this, as a betrayal by philosophers of the scientific revolution, which gave us true objectivity (e.g. about how the world was before humanity). |
| 19666 | If we insist on Sufficient Reason the world will always be a mystery to us [Meillassoux] |
| Full Idea: So long as we continue to believe that there is a reason why things are the way they are rather than some other way, we will construe this world is a mystery, since no such reason will every be vouchsafed to us. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 4) | |
| A reaction: Giving up sufficient reason sounds like a rather drastic response to this. Put it like this: Will we ever be able to explain absolutely everything? No. So will the world always be a little mysterious to us? Yes, obviously. Is that a problem? No! |
| 19656 | Non-contradiction is unjustified, so it only reveals a fact about thinking, not about reality? [Meillassoux] |
| Full Idea: The principle of non-contradiction itself is without reason, and consequently it can only be the norm for what is thinkable by us, rather than for what is possible in the absolute sense. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 2) | |
| A reaction: This is not Meillassoux's view, but describes the modern heresy of 'correlationism', which ties all assessments of how reality is to our capacity to think about it. Personally I take logical non-contradiction to derive from non-contradiction in nature. |
| 4955 | Some definitions aim to fix a reference rather than give a meaning [Kripke] |
| Full Idea: Some things called definitions really intend to fix a reference rather than to give the meaning of a phrase, to give a synonym. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: His example is pi. Some definitions relate to reality (e.g. ostensive definition), and others are part of a language game. But then some concepts are dictated to us by reality, and others are arbitrarily invented by us for convenience. |
| 20380 | Why should truth be omnipotent? It is enough that it is very powerful [Nietzsche] |
| Full Idea: I have no idea why the dictatorship and omnipotence of truth would be desirable; it's sufficient for me that it has great power. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], §507) | |
| A reaction: I once heard a philosopher (at Essex University) assert that truth is the only value, which was interesting. Nietzsche actually wants to endorse the value of lies and deceptions, like the 'noble lie' in Plato's Republic. |
| 20235 | Like animals, we seek truth because we want safety [Nietzsche] |
| Full Idea: Even that nose for truth, which is, at bottom, the nose for safety, human beings have in common with animals. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 026) | |
| A reaction: After Darwin, Nietzsche immediately saw that we need an account of humanity which is continuous with animals. The first step to physical security is ascertaining the physical facts. This idea rings true. |
| 10559 | Kripke's modal semantics presupposes certain facts about possible worlds [Kripke, by Zalta] |
| Full Idea: Kripke's modal semantics presupposes that worlds are maximal and consistent, that there is a unique actual world, and that worlds are coherent (e.g. lack contradiction, obey conjunction). | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Edward N. Zalta - Deriving Kripkean Claims with Abstract Objects |
| 19663 | We can allow contradictions in thought, but not inconsistency [Meillassoux] |
| Full Idea: For contemporary logicians, it is not non-contradiction that provides the criterion for what is thinkable, but rather inconsistency. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 3) | |
| A reaction: The point is that para-consistent logic might permit isolated contradictions (as true) within a system, but it is only contradiction across the system (inconsistencies) which make the system untenable. |
| 19664 | Paraconsistent logics are to prevent computers crashing when data conflicts [Meillassoux] |
| Full Idea: Paraconsistent logics were only developed in order to prevent computers, such as expert medical systems, from deducing anything whatsoever from contradictory data, because of the principle of 'ex falso quodlibet'. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 3) |
| 19665 | Paraconsistent logic is about statements, not about contradictions in reality [Meillassoux] |
| Full Idea: Paraconsistent logics are only ever dealing with contradictions inherent in statements about the world, never with the real contradictions in the world. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 3) | |
| A reaction: Thank goodness for that! I can accept that someone in a doorway is both in the room and not in the room, but not that they are existing in a real state of contradiction. I fear that a few daft people embrace the logic as confirming contradictory reality. |
| 10437 | Names are rigid, making them unlike definite descriptions [Kripke, by Sainsbury] |
| Full Idea: It was important to Kripke to contrast the rigidity of names with the non-rigidity of many or most definite descriptions. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Mark Sainsbury - The Essence of Reference 18.6 | |
| A reaction: Philosophers always want sharp distinctions, but there are tricky names like 'Homer' and 'Jack the Ripper' where the name is stable, but its referent wobbles. |
| 4949 | Names are rigid designators, which designate the same object in all possible worlds [Kripke] |
| Full Idea: I will call something a 'rigid designator' if in every possible world it designates the same object, ..and I will maintain the intuitive thesis that names are rigid designators. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: The immediate problem seems to be objects that change across possible worlds. Did nature rigidly designate Aristotle (e.g. by his DNA)? Could Aristotle have been shorter, female, cleverer, his own twin? Is the River Thames rigid? |
| 4951 | A bundle of qualities is a collection of abstractions, so it can't be a particular [Kripke] |
| Full Idea: I deny that a particular is nothing but a 'bundle of qualities', whatever that may mean. If a quality is an abstract object, a bundle of qualities is an object of an even higher degree of abstraction, not a particular. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: Supports the 'baptism' view of reference, rather than Searle's bundle of descriptions. It shows that theories of reference must tie in with theories of universals, and that Searle is a nominalist. Is Kripke trying to duck metaphysical responsibility? |
| 17031 | A name can still refer even if it satisfies none of its well-known descriptions [Kripke] |
| Full Idea: Suppose the vote yields no object, that nothing satisfies most, or even any, substantial number, of the φ's. Does that mean the name doesn't refer? No. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 2) | |
| A reaction: As example he gives the case of 'Gödel' referring to the famous man, even if none of the descriptions of him are true. In Note 42 he blames the descriptivists for relying too much on famous people. |
| 8957 | Some references, such as 'Neptune', have to be fixed by description rather than baptism [Kripke, by Szabó] |
| Full Idea: Kripke explicitly allows for the introduction of names through initial reference-fixing via descriptions. Versions of the causal theory of reference that disallow this would have a difficult time explaining how the name 'Neptune' came to refer. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Zoltán Gendler Szabó - Nominalism 4.2 n35 | |
| A reaction: The initial reference to Neptune has to be by description, but you could still give a baptismal account once it is discovered. The direct contact now takes precedence. Suppose another similar planet was found nearby... |
| 10428 | Proper names must have referents, because they are not descriptive [Kripke, by Sainsbury] |
| Full Idea: A common source of the view that proper names must have referents is that they are not descriptive (as expressed by Kripke). | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Mark Sainsbury - The Essence of Reference 18.2 | |
| A reaction: Sainsbury observes that there might be some other way for a name to be intelligible, with describing or referring. |
| 4959 | A name's reference is not fixed by any marks or properties of the referent [Kripke] |
| Full Idea: It is in general not the case that the reference of a name is determined by some uniquely identifying marks, some unique properties satisfied by the referent and known or believed to be true of that referent by the speaker. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: He is proposing, instead, his historical/causal theory. There does seem to be a problem with objects which have a historical 'baptism', and then entirely change their properties. Kripke us desperate for a simple account of reference. |
| 19677 | What is mathematically conceivable is absolutely possible [Meillassoux] |
| Full Idea: We must establish the thesis that what is mathematically conceivable is absolutely possible. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 5) | |
| A reaction: The truth of this thesis would permanently establish mathematics as the only possible language of science. Personally I have no idea how you could prove or assess such a thesis. It is a lovely speculation, though. 'The structure of the possible' (p,127) |
| 19659 | The absolute is the impossibility of there being a necessary existent [Meillassoux] |
| Full Idea: We maintain that it is absolutely necessary that every entity might not exist. ...The absolute is the absolute impossibility of a necessary being. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 3) | |
| A reaction: This is the main thesis of his book. The usual candidates for necessary existence are God, and mathematical objects. I am inclined to agree with Meillassoux. |
| 19662 | It is necessarily contingent that there is one thing rather than another - so something must exist [Meillassoux] |
| Full Idea: It is necessary that there be something rather than nothing because it is necessarily contingent that there is something rather than something else. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 3) | |
| A reaction: The great charm of metaphysics is the array of serious answers to the question of why there is something rather than nothing. You'll need to read Meillassoux's book to understand this one. |
| 19654 | We must give up the modern criterion of existence, which is a correlation between thought and being [Meillassoux] |
| Full Idea: It is incumbent upon us to break with the ontological requisite of the moderns, according to which 'to be is to be a correlate'. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 2) | |
| A reaction: He blames Kant for this pernicious idea, which has driven philosophy away from realist science, when it should be supporting and joining it. As a realist I agree, and find Meillassoux very illuminating on the subject. |
| 14896 | Kripke's metaphysics (essences, kinds, rigidity) blocks the slide into sociology [Kripke, by Ladyman/Ross] |
| Full Idea: Kripke's metaphysics of essences, natural kinds, and rigid designation gave philosophers a means of avoiding the relativist path that was bound to end in the tears of sociology. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by J Ladyman / D Ross - Every Thing Must Go 1.2 | |
| A reaction: They are contemptuous of Kripke's project, but this is the core of it. He was making a stand against Kuhn, and trying to build a metaphysics for realism. Good for Kripke. |
| 17647 | Kripke individuates objects by essential modal properties (and presupposes essentialism) [Kripke, by Putnam] |
| Full Idea: The difficulty is that Kripke individuates objects by their modal properties, by what they (essentially) could and could not be. Kripke's ontology presupposes essentialism; it can not be used to ground it. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Hilary Putnam - Why there isn't a ready-made world 'Essences' |
| 16995 | Given that a table is made of molecules, could it not be molecular and still be this table? [Kripke] |
| Full Idea: This table is composed of molecules. …Could anything be this very object and not be composed of molecules? …It's hard to imagine under what circumstances you would have this very object and find that it is not composed of molecules. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: This is the thesis of essentiality of constitution. Given that it is square, might it have been round? Yes. Given that it is wood, might it have been metal? No? Given that it is molecular, might it have been plasma? No. ….Maybe. |
| 17047 | If we imagine this table made of ice or different wood, we are imagining a different table [Kripke] |
| Full Idea: Though we can imagine a table identical to this one in this room, but made of ice (or different wood), it seems to me that this is not to imagine this table as made of ice, but to imagine another table, resembling this one, made of ice. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: This is the Necessity of Constitution thesis, which I doubt. Might this table have had one leg different? Why not? Then you have a Ship of Theseus question. How much could be different? How much of the constitution is necessary? |
| 5450 | For Kripke, essence is origin; for Putnam, essence is properties; for Wiggins, essence is membership of a kind [Kripke, by Mautner] |
| Full Idea: Kripke makes the origin of an organism essential to it, according to Putnam the fundamental physical properties of a thing are essential, Wiggins sees an organism's essence in belonging to a particular kind, etc. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Thomas Mautner - Penguin Dictionary of Philosophy p.179 | |
| A reaction: This is helpful for seeing where the problems remain, if you embrace essentialism (as I feel inclined to do). It is vital to remember Putnam's point, that we could suddenly discover that cats are alien robots. This seems to undermine Kripke and Wiggins. |
| 17055 | Atomic number 79 is part of the nature of the gold we know [Kripke] |
| Full Idea: It is part of the nature of gold as we have it to be an element with atomic number 79. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: The word 'nature' directly invokes Aristotle's concept of an essence. Scientific essentialism arises from the idea that by discovering the atomic number, we have somehow 'arrived' at the essence, and enquiry is reaching its terminus. |
| 16997 | An essential property is true of an object in any case where it would have existed [Kripke] |
| Full Idea: When we think of a property as essential to an object we usually mean that it is true of that object in any case where it would have existed. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: This seems to equate essence with necessary properties, which is the view attacked nicely be Fine in 1994. I take essence (in Aristotle's sense) to be quite different from necessary properties (in being non-trivial, for example). |
| 17045 | De re modality is an object having essential properties [Kripke] |
| Full Idea: De re modality is an object having essential properties. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: [Plucked out of context] It is because Kripke says there are necessities about things, and not just about statements about things, that he has caused a revival of essentialism. Fine has famously said modality depends on essence. |
| 17030 | Important properties of an object need not be essential to it [Kripke] |
| Full Idea: Important properties of an object need not be essential, unless 'importance' is used as a synonym for essence. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 2) | |
| A reaction: Kripke's examples are the writings of Aristotle and the actions of Hitler, but these don't strike me as being 'properties' of those people. They are not intrinsic. Kripke, of course, is concerned with how we identify them, not who they actually are. |
| 16955 | Kripke says internal structure fixes species; I say it is genetic affinity and a common descent [Kripke, by Dummett] |
| Full Idea: Kripke stresses that membership of a single animal species requires identity or similarity of internal structure. In my view, what matters is genetic affinity - a common descent. Internal structure is merely a clue. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Michael Dummett - Could There Be Unicorns? 2 | |
| A reaction: The crucial test question would be whether we can make a tiger artificially (even constructing the DNA). I would say that if you make a tiger, that's a tiger, so Kripke is right and Dummett is wrong. The species is what it is, not where it came from. |
| 16996 | Given that Nixon is indeed a human being, that he might not have been does not concern knowledge [Kripke] |
| Full Idea: Suppose Nixon actually turned out to be an automaton. That might happen. But that is a question about our knowledge. The question of whether he might not have been a human being, given that he is one, is not a question about knowledge. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: Given that you are sitting, might you be standing? Yes. Given that you are human, might you be non-human? No. Maybe! |
| 13971 | Kripke claims that some properties, only knowable posteriori, are known a priori to be essential [Kripke, by Soames] |
| Full Idea: Kripke's first (good) route to the necessary a posteriori is based on the idea that certain properties of objects that they can be known to have only a posteriori, may be known a priori to be essential properties of anything that has them. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Scott Soames - Significance of the Kripkean Nec A Posteriori p.180 | |
| A reaction: Interesting, and a key issue. I think this is precisely where I disagree with the Kripkean view of necessities. Logicians want to know a priori what is essential for identity, but scientists want to know what makes things tick. See Kripke on pain. |
| 12100 | An essence is the necessary properties, derived from an intuitive identity, in origin, type and material [Kripke, by Witt] |
| Full Idea: For Kripke an object's essence simply consists of its necessary properties. ...His essential properties of individual objects follow from our intuitions about their identity. ...They are of three sorts: of origin, of sortals, and of material. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Charlotte Witt - Substance and Essence in Aristotle 6 n3 | |
| A reaction: This is because Kripke is only interested in identity, whereas Aristotle is interested in explanation. The sorts are efficient, formal, material. Big Q: could Aristotle's account of essence do all the work that is required of essences by Kripke? |
| 16991 | No one seems to know the identity conditions for a material object (or for people) over time [Kripke] |
| Full Idea: Adequate necessary and sufficient conditions for identity which do not beg the question are very rare. …I don't know of such conditions for identity of material objects over time, or for people. Everyone knows what a problem this is. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: Typical of Kripke, who only seems to commit to conclusions suggested to him by his modal logic, and is baffled by almost everything else. I think one can at least attempt an essentialist approach to this problem. |
| 11867 | If we lose track of origin, how do we show we are maintaining a reference? [Kripke, by Wiggins] |
| Full Idea: Perhaps Kripke's argument for the necessity to a thing of its actual origin is that the speculator has to be able to rebut the charge that he has lost his grasp of his subject of discourse if he conceives of this subject with changed parents or origin. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by David Wiggins - Sameness and Substance Renewed 4.10 | |
| A reaction: On the whole Wiggins opposes necessity of origin (cf. Forbes, who defends it). If this idea is right, then any means of ensuring reference will do the job, and it clearly wouldn't be an argument that guaranteed necessity of origin. |
| 12018 | Kripke argues, of the Queen, that parents of an organism are essentially so [Kripke, by Forbes,G] |
| Full Idea: If we generalise what Kripke says about the Queen, then he is arguing that the parents of any organism are essentially the parents of that organism. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Graeme Forbes - The Metaphysics of Modality 6.1 | |
| A reaction: It strikes me that we have to be extremely careful in specifying what it is that Kripke is saying. I take it that either Kripke is saying something rather uninteresting, or he is saying what Forbes suggests. Parenthood is essential, not just necessary. |
| 17046 | Could the actual Queen have been born of different parents? [Kripke] |
| Full Idea: Could the Queen - could this woman herself - have been born of different parents from the parents from whom she actually came? | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: Tricky! No, because the past is fixed? Could the Queen have visited Russia when she was 20? I suppose so. Might she not have had parents, given who she is? I don't see why not. Could this desk have been made by someone else? Why not? |
| 8274 | Socrates can't have a necessary origin, because he might have had no 'origin' [Lowe on Kripke] |
| Full Idea: Against Kripke's thesis of 'necessity of origin' I will just point out the intuitive force of the claim that Socrates - that very person - could, logically, have had no beginning to his existence at all, or have come into existence ex nihilo. | |
| From: comment on Saul A. Kripke (Naming and Necessity lectures [1970], p.110-) by E.J. Lowe - The Possibility of Metaphysics 6.5 | |
| A reaction: It also strikes me that one base-pair difference in his DNA (by a mutation, or a fractionally different parent) would still leave him as Socrates. People are not good candidates for 'rigid' designation. Counterparts seems a better account here. |
| 17036 | Identity statements can be contingent if they rely on descriptions [Kripke] |
| Full Idea: If the man who invented bifocals was the first Postmaster General of the United States - that they were one and the same - it's contingently true. …So when you make identity statements using descriptions, that can be a contingent fact. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 2) |
| 17038 | If Hesperus and Phosophorus are the same, they can't possibly be different [Kripke] |
| Full Idea: If Hesperus and Phosphorus are one and the same, then in no other possible world can they be different. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 2) | |
| A reaction: If we ask whether one object could possibly be two objects, and deny that possibility, then Kripke's novel thought seems just right and obvious. |
| 11880 | Kripke says his necessary a posteriori examples are known a priori to be necessary [Kripke, by Mackie,P] |
| Full Idea: Kripke claims that all of his examples of the necessary a posteriori have the characteristic that we can know a priori that if they are true, they are necessarily true. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970], 159) by Penelope Mackie - How Things Might Have Been 1.4 | |
| A reaction: That is, it seems, that they are not really necessary a posteriori! The necessity seems to only arrive with the addition of a priori judgements, thus endorsing the traditional view that necessity is only derivable a priori. Hm. |
| 4797 | Instead of being regularities, maybe natural laws are the weak a posteriori necessities of Kripke [Kripke, by Psillos] |
| Full Idea: By defending a posteriori necessary statements, Kripke introduced the concept of a necessity in nature that was weaker than logical necessity; ..as a result, the dominant view of laws as mere regularities started to be seriously challenged. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Stathis Psillos - Causation and Explanation §6.1 | |
| A reaction: Most of Kripke's examples of discovered necessities seem to be identities, which seem to be as strong as any logical necessity. I'm not sure I can make sense of a 'less strong necessity'. Necessity sounds all-or-nothing to me. |
| 17037 | Physical necessity may be necessity in the highest degree [Kripke] |
| Full Idea: Physical necessity might turn out to be necessity in the highest degree. But that's a question which I don't wish to prejudge. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 2) | |
| A reaction: Presumably necessity 'in the highest degree' is 'metaphysical' necessity, but Kripke is a bit coy about that. This is the germ of modern scientific essentialism. |
| 19660 | Possible non-being which must be realised is 'precariousness'; absolute contingency might never not-be [Meillassoux] |
| Full Idea: My term 'precariousness' designates a possibility of not-being which must eventually be realised. By contrast, absolute contingency designates a pure possibility; one which may never be realised. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 3) | |
| A reaction: I thoroughly approve of this distinction, because I have often enountered the assumption that all contingency is precariousness, and I have never seen why that should be so. In Aquinas's Third Way, for example. The 6 on a die may never come up. |
| 19671 | The idea of chance relies on unalterable physical laws [Meillassoux] |
| Full Idea: The very notion of chance is only conceivable on condition that there are unalterable physical laws. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 4) | |
| A reaction: Laws might be contingent, even though they never alter. Chance in horse racing relies on the stability of whole institution of horse racing. |
| 4728 | Kripke separates necessary and a priori, proposing necessary a posteriori and contingent a priori examples [Kripke, by O'Grady] |
| Full Idea: It is now recognised that the apriori and the necessary don't always have to go together, ..and Kripke has suggested examples of necessary-aposteriori and contingent-apriori beliefs. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Paul O'Grady - Relativism Ch.4 | |
| A reaction: The simple point is that whether something is necessary or contingent is a quite separate question from how we come to know that they are. There isn't a new mode of reality called 'necessary a posteriori'. |
| 16990 | A priori = Necessary because we imagine all worlds, and we know without looking at actuality? [Kripke] |
| Full Idea: People think 'necessary' and 'a priori' mean the same for two reasons: we can assess what is feasible in all possible world by running them through our heads, and something known a priori avoids looking at the world, so it must be necessary. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: [compressed] Kripke denies this doctrine, and pulls the concepts apart. Kant seems to be the chief representative of the view he is attacking. Hossack defends the older view. |
| 9386 | The meter is defined necessarily, but the stick being one meter long is contingent a priori [Kripke] |
| Full Idea: In 'one meter is the length of stick S at t', one designator (one meter) is rigid and the other (length of S at t) is not. 'S is one meter long at t' is contingent, as it could have a different length. In this sense, there are contingent a priori truths. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: [very compressed] Not convincing. He is proposing that a truth is knowable a priori, though knowledge of it is utterly dependent on a ceremony having taken place. It would not be true if that event hadn't taken place, so how can be it be known a priori? |
| 4960 | "'Hesperus' is 'Phosphorus'" is necessarily true, if it is true, but not known a priori [Kripke] |
| Full Idea: An identity statement between names (such as 'Hesperus' and 'Phosphorus'), when true at all, is necessarily true, even though one may not know it a priori. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: This seems correct, but one should not read too much into it. What should we say if Venus fissions into two, one for the morning, one for the evening? That identity implies x=x doesn't prove the existence of unchanging essences. |
| 4966 | Theoretical identities are between rigid designators, and so are necessary a posteriori [Kripke] |
| Full Idea: Theoretical identities, according to the conception I advocate, are generally identities involving rigid designators and therefore are examples of the necessary a posteriori. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: This doesn't open up a huge new realm of a posteriori necessity. We just cured some of our ignorance. I remain unconvinced that the Morning Star is necessarily the Evening Star, except in the boring way that if it is, it is. Venus could fission. |
| 2408 | Kripke has demonstrated that some necessary truths are only knowable a posteriori [Kripke, by Chalmers] |
| Full Idea: Kripke has demonstrated the existence of necessary truths such as "water is H2O" whose necessity is only knowable a posteriori. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by David J.Chalmers - The Conscious Mind 2.4.2 |
| 13967 | Kripke's essentialist necessary a posteriori opened the gap between conceivable and really possible [Soames on Kripke] |
| Full Idea: With Kripke's essentialist route to the necessary a posteriori came a sharp distinction between conceivability and genuine possibility - ways things could conceivably be versus ways things could really be (or have been). | |
| From: comment on Saul A. Kripke (Naming and Necessity lectures [1970]) by Scott Soames - Significance of the Kripkean Nec A Posteriori p.167 | |
| A reaction: A key idea, for me. I love 'could there be a bonfire on the moon?' Imagining it is easy-peasy. 'Could wood combine with oxygen when there is no oxygen present?' We imagined it all right, but did we 'conceive' it? |
| 13970 | Kripke gets to the necessary a posteriori by only allowing conceivability when combined with actuality [Kripke, by Soames] |
| Full Idea: Kripke's first (superior) route to necessary a posteriori has a sharp distinction between how the universe could conceivably and really be. ..On this picture conceivability is a fallible but useful guide, when combined with knowledge of actuality. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Scott Soames - Significance of the Kripkean Nec A Posteriori p.168 | |
| A reaction: [compressed from p.168 and 170] To dismiss conceivability is ridiculous (see Williamson on that), and this formula of Soames sound right. To understand possibility, you have to study actuality (across time and space). Study history! |
| 16992 | Possible worlds aren't puzzling places to learn about, but places we ourselves describe [Kripke] |
| Full Idea: A possible world isn't a distant country that we are coming across, or viewing through a telescope. …A possible world is given by the descriptive conditions we associate with it. …Possible worlds are stipulated, not discovered by powerful telescopes. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: His point is that it is absurd to be puzzling over the identity of what exists in some possible world, because the world is specified by us. If I say 'Nixon might have been a frog', I must be referring to Nixon. The problem is whether it is true. |
| 16993 | If we discuss what might have happened to Nixon, we stipulate that it is about Nixon [Kripke] |
| Full Idea: There is no reason why we cannot stipulate that, in talking about what would have happened to Nixon in a certain counterfactual situation, we are talking about what would have happened to HIM. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: For many people (including me now, I think) this lays to rest the supposed problem of 'transworld identity' wrestled with by Kaplan and Lewis. |
| 16998 | Transworld identification is unproblematic, because we stipulate that we rigidly refer to something [Kripke] |
| Full Idea: It is because we refer (rigidly) to Nixon, and stipulate that we are speaking of what might have happened to him (under certain circumstances), that 'transworld identifications' are unproblematic in such cases. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: This responds to those who say you need transworld identification before you can rigidly designate something, which has 'reversed the cart and horse' says Kripke. Nice. |
| 17001 | A table in some possible world should not even be identified by its essential properties [Kripke] |
| Full Idea: A table should not be identified with the set or 'bundle' of its properties, nor with the subset of its essential properties. Don't ask: how can I identify this table in another possible world, except by its properties? I have the table in my hands. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: You identify the table by what's in front of you, but the essence might be relevant to deciding how far this table could change and remain this table. |
| 4952 | Identification across possible worlds does not need properties, even essential ones [Kripke] |
| Full Idea: Some properties of an object may be essential to it, in that it could not have failed to have them. But these properties are not used to identify the object in another possible world, for such an identification is not needed. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: So how DO you identify objects in other possible worlds, or in this one? You may say he was baptised 'Aristotle' so that's rigid, but if Athens is full of pseudo-Aristotles I want to pick out the real one. I say Kripke muddles epistemology and ontology. |
| 7761 | Test for rigidity by inserting into the sentence 'N might not have been N' [Kripke, by Lycan] |
| Full Idea: Kripke offers an intuitive test for telling whether a term is rigid: try the term in the sentence-frame "N might not have been N". (For example, try the terms 'Nixon' and 'President of the USA'). | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by William Lycan - Philosophy of Language Ch.4 | |
| A reaction: Helpful, but if you try it, the results do not seem to be conclusive. You are left saying 'Well, it depends what you mean by...' Think of possible worlds with a crippled Nixon, twin Nixons, an honest Nixon, a robot Nixon, a dark skinned Nixon... |
| 7693 | Kripke avoids difficulties of transworld identity by saying it is a decision, not a discovery [Kripke, by Jacquette] |
| Full Idea: Objects we find in the actual world might have been so different than they actually are that it appears impossible to identify the same objects from world to world. Kripke sidesteps the problem by saying transworld identity is a decision, not a discovery. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Dale Jacquette - Ontology Ch.2 | |
| A reaction: This is the strategy that opposes Lewis's proposal of 'counterpart' objects that have properties in common. It is also the source of Kripke's causal theory of reference, and hence a key to massive modern debates. |
| 5821 | Saying that natural kinds are 'rigid designators' is the same as saying they are 'indexical' [Kripke, by Putnam] |
| Full Idea: Kripke's doctrine that natural kind words are rigid designators and our doctrine that they are indexical are two ways of making the same point. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Hilary Putnam - Meaning and Reference p.161 | |
| A reaction: I think I prefer Putnam's terminology, because it is more modest in its claims Kripke gets into trouble when a natural kind in some other possible world is only subtly different from the original. How 'rigid'? Putnam sticks to how the word gets started. |
| 14068 | If Kripke names must still denote a thing in a non-actual situation, the statue isn't its clay [Gibbard on Kripke] |
| Full Idea: Kripke gives an account of proper names from which it follows that Goliath (the statue) cannot be identical the lumpl (the clay), ..because if a proper name denotes a thing in the actual world, then it denotes that same thing in non-actual situations. | |
| From: comment on Saul A. Kripke (Naming and Necessity lectures [1970]) by Allan Gibbard - Contingent Identity III | |
| A reaction: This strikes me as a powerful criticism of Kripke's claim - and has led to extensive discussion which I will now have to pursue. Watch this space. |
| 10436 | A rigid expression may refer at a world to an object not existing in that world [Kripke, by Sainsbury] |
| Full Idea: In the Kripkean perspective, rigidity is understood in such a way that an expression may have as referent at a world an object which does not exist at that world. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Mark Sainsbury - The Essence of Reference 18.6 | |
| A reaction: This means that 'the present King of France' is a rigid designator. |
| 4953 | We do not begin with possible worlds and place objects in them; we begin with objects in the real world [Kripke] |
| Full Idea: We do not begin with worlds (which are supposed somehow to be real), and then ask about criteria of transworld identification; on the contrary, we begin with objects, which we have, and can identify, in the real world. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: This gives us clearly Kripke's underlying empiricist metaphysics, I take it. I find the realism of it appealing, but am uneasy about the idea of an object as basic, when Heraclitus said that they tend to fluctuate. Platonism waits in the wings. |
| 4961 | It is a necessary truth that Elizabeth II was the child of two particular parents [Kripke] |
| Full Idea: How could a person originating from different parents, from a totally different sperm and egg, be this very woman (Elizabeth II)? ..It seems to me that anything coming from a different origin would not be this very object. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: Since baby Elizabeth could have been smuggled into the palace in a bedpan, it seems to me that her properties now are rather more obvious than her origin. I fear the only necessity here is that you can't change the past. An intriguing puzzle. |
| 16986 | That there might have been unicorns is false; we don't know the circumstances for unicorns [Kripke] |
| Full Idea: I think it is not the case that there might have been unicorns. I wouldn't say it is necessary that there are no unicorns, but that we just can't say under what circumstances there would have been unicorns. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: His point seems to be that unicorns are insufficiently individuated by the legends, whereas a typical sample of an actual creature contains everything that will individuate the species. |
| 20258 | Most people treat knowledge as a private possession [Nietzsche] |
| Full Idea: Most people take a thing they know under their protection, as if knowing it turned it into their possession. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 285) | |
| A reaction: A typically wicked and subtle remark. This presumably makes knowledge part of the will to power, with which Francis Bacon would presumably agree. |
| 19651 | Unlike speculative idealism, transcendental idealism assumes the mind is embodied [Meillassoux] |
| Full Idea: What distinguishes transcendental idealism from speculative idealism is the fact that the former does not posit the existence of the transcendental subject apart from its bodily individuation. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 1) | |
| A reaction: These modern French philosophers explain things so much more clearly than the English! The 'speculative' version is seen in Berkeley. On p.17 he says transcendental idealism is 'civilised', and speculative idealism is 'uncouth'. |
| 8259 | Kripke has breathed new life into the a priori/a posteriori distinction [Kripke, by Lowe] |
| Full Idea: The a priori/a posteriori is still taken seriously, and has had new life breathed into it by the work of Saul Kripke. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by E.J. Lowe - The Possibility of Metaphysics 1.1 | |
| A reaction: The distinction may be a good one, despite a blurred borderline. Did Egyptian quantity surveyors begin to suspect that Pythagoras's Theorem was a necessary truth, though they couldn't prove it? A priori understanding creeps into experience. |
| 16989 | Rather than 'a priori truth', it is best to stick to whether some person knows it on a priori evidence [Kripke] |
| Full Idea: A priori is supposed to mean something which can be known independently of experience, …but possible for whom? God, or the Martians? …Instead of 'a priori truth' it is best to stick to whether some person knows it based on a priori evidence. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: [compressed] This is Kripke's famous attempt to establish that 'a priori' is strictly an epistemological term, and should not be taken as a term of metaphysics (or modal semantics?). I definitely prefer the Kripke view, though it downgrades the a priori. |
| 4947 | A priori truths can be known independently of experience - but they don't have to be [Kripke] |
| Full Idea: The traditional characterisation (since Kant) goes: a priori truths are those which can be known independently of any experience - ..but that doesn't mean they MUST be known a priori. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: You may discover through experience that nine matches can't be divided into two equal piles, but Leibniz (and others) say you will only see the necessity of this a priori. No necessity is visible in the matches. |
| 13975 | Kripke was more successful in illuminating necessity than a priority (and their relations to analyticity) [Kripke, by Soames] |
| Full Idea: Kripke was far more successful in illuminating the nature of necessity, and distinguishing it from both apriority and analyticity, than he was in illuminating the nature of apriority, and distinguishing that from analyticity. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Scott Soames - Significance of the Kripkean Nec A Posteriori p.187 |
| 17048 | Analytic judgements are a priori, even when their content is empirical [Kripke] |
| Full Idea: All analytic judgements are a priori even when the concepts are empirical, as, for example, 'Gold is a yellow metal'; for to know this I require no experience beyond my concept of gold as a yellow metal. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: So I relate a priori to 'turquoise is a shade of red', even though my concepts are confused? It is my concept, perhaps, but it is false. I thought a priori had something to do with knowing, not with reporting the confused nonsense in my mind? |
| 19647 | The aspects of objects that can be mathematical allow it to have objective properties [Meillassoux] |
| Full Idea: All aspects of the object that can give rise to a mathematical thought rather than to a perception or a sensation can be meaningfully turned into the properties of the thing not only as it is with me, but also as it is without me. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 1) | |
| A reaction: This is Meillassoux's spin on the primary/secondary distinction, which he places at the heart of the scientific revolution. Cartesian dualism offers a separate space for the secondary qualities. He is appalled when philosophers reject the distinction. |
| 4948 | Intuition is the strongest possible evidence one can have about anything [Kripke] |
| Full Idea: I think something's having intuitive content is very heavy evidence in favour of it. I really don't know what more conclusive evidence one can have about anything, ultimately speaking. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) | |
| A reaction: This seems to me a very appealing remark, especially coming from a great logician. It seems to me, though, that some intuitions are more rational than others, and we must occasionally give up intuitions that are proved wrong. |
| 20250 | We may be unable to remember, but we may never actually forget [Nietzsche] |
| Full Idea: It has yet to be proven that there is such a thing as forgetting; all we know is that the act of remembering is not within our power. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 126) | |
| A reaction: There is some evidence for this. We forget innumerable people, but then find that we recognise them if we meet them many years later. Anecdotes report very ancient memories suddenly surfacing. |
| 20270 | There is no one scientific method; we must try many approaches, and many emotions [Nietzsche] |
| Full Idea: There is no one and only scientific method that leads to knowledge. We must proceed experimentally with things, be sometimes angry, sometimes affectionate towards them, and allow justice, passion, and coldness to follow one upon another. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 432) | |
| A reaction: Alexander Bird says the same thing in our time. I agree, but I think there is a core of controlled conditions and peer review. |
| 4958 | Identities like 'heat is molecule motion' are necessary (in the highest degree), not contingent [Kripke] |
| Full Idea: I hold that characteristic theoretical identifications like 'heat is the motion of molecules', are not contingent truths but necessary truths, and I don't just mean physically necessary, but necessary in the highest degree. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 2) | |
| A reaction: This helps to keep epistemology and ontology separate. The contingency was in the epistemology. That the identity is 'physically necessary' seems obvious; that it is necessary 'in the highest degrees' implies an essentialist view of nature. |
| 19652 | How can we mathematically describe a world that lacks humans? [Meillassoux] |
| Full Idea: How is mathematical discourse able to describe a reality where humanity is absent? | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 1) | |
| A reaction: He is referring to the prehistoric world. He takes this to be a key question about the laws of nature. We extrapolate mathematically from the experienced world, relying on the stability of the laws. Must they be necessary to be stable? No, it seems. |
| 19668 | Hume's question is whether experimental science will still be valid tomorrow [Meillassoux] |
| Full Idea: Hume's question can be formulated as follows: can we demonstrate that the experimental science which is possible today will still be possible tomorrow? | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 4) | |
| A reaction: Could there be deep universal changes going on in nature which science could never, even in principle, detect? |
| 20131 | We can cultivate our drives, of anger, pity, curiosity, vanity, like a gardener, with good or bad taste [Nietzsche] |
| Full Idea: One can dispose of one's drives like a gardener and, though few know it, cultivate the shoots of anger, pity, curiosity, vanity as productively and profitably as a beautiful fruit tree on a trellis; one can do it with the good or bad taste of a gardener. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 560) | |
| A reaction: This sort of existentialism I find very appealing. You take what you are given, the cards you are dealt, and try to make something nice out of it. This is quite different from the crazy freedom of later existentialists. |
| 19650 | The transcendental subject is not an entity, but a set of conditions making science possible [Meillassoux] |
| Full Idea: The transcendental subject simply cannot be said to exist; which is to say that the subject is not an entity, but rather a set of conditions rendering objective scientific knowledge of entities possible. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 1) | |
| A reaction: Meillassoux treats this as part of the Kantian Disaster, which made an accurate account of the scientific revolution impossible for philosophers. Kant's ego seems to have primarily an epistemological role. |
| 20242 | Things are the boundaries of humanity, so all things must be known, for self-knowledge [Nietzsche] |
| Full Idea: Only when the human being has finally attained knowledge of all things will he have known himself. For things are merely the boundaries of the human being. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 048) | |
| A reaction: This seems to be a rather externalist view of the mind. If philosophy aims to disentangle mind from world then good knowledge of the world seems to be required. |
| 20249 | Our knowledge of the many drives that constitute us is hopelessly incomplete [Nietzsche] |
| Full Idea: No matter how hard a person struggles for self-knowledge, nothing can be more incomplete than the image of all the drives taken together than constitute his being. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 119) | |
| A reaction: This gives the concept of personal identity that arises from the (later) doctrine of the 'will to power'. It is a bundle view of the self, but a bundle of drives rather than of percepts and mental events. His view is close to Hume's. |
| 20231 | People used to think that outcomes were from God, rather than consequences of acts [Nietzsche] |
| Full Idea: People used to believe that the outcome of an action was not a consequence, but an independent, supplemental ingredient, namely God's. Is a greater confusion conceivable? | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 012) | |
| A reaction: Not sure how well documented or accurate this is, but Nietzsche was a great scholar, and it would explain the fatalism that runs through many older forms of society. |
| 4967 | It seems logically possible to have the pain brain state without the actual pain [Kripke] |
| Full Idea: Prima facie, it would seem that it is a least logically possible the brain state corresponding to pain should have existed (Jones's brain could have been in exactly that state at the time in question) without Jones feeling any pain at all. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: This is Kripke's commitment to the possibility of zombies, which are only possible if the mind-body connection is a contingent one, and he shows that there are no contingent 'identities'. The answer is necessary identity, and no zombies. |
| 7430 | Kripke assumes that mind-brain identity designates rigidly, which it doesn't [Armstrong on Kripke] |
| Full Idea: In his attempted disproof of materialism about the mind, Kripke assumes that the physical description is a rigid designator, but this seems to be begging the question against the causal theory, which says the description is non-rigid. | |
| From: comment on Saul A. Kripke (Naming and Necessity lectures [1970]) by David M. Armstrong - Pref to new 'Materialist Theory' p.xiv | |
| A reaction: A crucial part of this is that Armstrong believes that the laws of nature are contingent, and hence mind-brain identity has to be. Personally I incline to say that the identity is rigid, but that Kripke is still wrong. |
| 7867 | If consciousness could separate from brain, then it cannot be identical with brain [Kripke, by Papineau] |
| Full Idea: Kripke's argument is that the possibility of conscious properties coming apart from material properties shows that they cannot be identical with material properties. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by David Papineau - Thinking about Consciousness 3.3 | |
| A reaction: A nice clear and simple summary. How can the possibility of coming apart be demonstrated? Only, it seems, by using our imaginations. But that is quite a good guide in areas we know well, but not in recondite areas like the brain. |
| 3228 | Kripke says pain is necessarily pain, but a brain state isn't necessarily painful [Kripke, by Rey] |
| Full Idea: Kripke's argument against mind-brain identity is that a pain is necessarily pain (just as a stone is necessarily matter), but a brain state is not necessarily painful (just as a stone is not necessarily a doorstep). | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Georges Rey - Contemporary Philosophy of Mind 11.6.2 | |
| A reaction: As with Descartes' argument from necessity for dualism, this seems to me to beg the question. It seems to me fairly self-evident that certain brain states have to be painful, just as stones always have to be hard or massive. |
| 5832 | Identity must be necessary, but pain isn't necessarily a brain state, so they aren't identical [Kripke, by Schwartz,SP] |
| Full Idea: The identity theorist, it appears, can admit that the identity is necessary if true without substantially altering his position, but Kripke argues that the identity between pain and some brain states is not necessary. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) by Stephen P. Schwartz - Intro to Naming,Necessity and Natural Kinds §IV | |
| A reaction: This appears to depend on being able to imagine the pain occurring with a different brain state, or no brain state. Bad argument. See Idea 5819. |
| 4968 | Identity theorists seem committed to no-brain-event-no-pain, and vice versa, which seems wrong [Kripke] |
| Full Idea: The identity theorist is committed to the view that there could not be a C-fibre stimulation which was not a pain, nor a pain which was not a C-fibre stimulation; these consequences are certainly surprising and counterintuitive. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: If Kripke saw a glow in an area of his brain every time he felt a pain, he would cease to find it 'counterintuitive'. Far from this conclusion being 'surprising', its opposite is absurd. Pain with no brain event? C-fibres blaze away, and I feel nothing? |
| 17874 | Kripke has a definitional account of kinds, but not of naming [Almog on Kripke] |
| Full Idea: There seems to be an incongruity between Kripke's definitionalist account of the essence of kinds (and the induced necessities), and his definition-free account of naming. | |
| From: comment on Saul A. Kripke (Naming and Necessity lectures [1970]) by Joseph Almog - Nature Without Essence X | |
| A reaction: Putnam places more emphasis on baptising a prototypical example, just as we baptise named things. |
| 16394 | Kripke derives accounts of reference and proper names from assumptions about worlds and essences [Stalnaker on Kripke] |
| Full Idea: One might think that the direction of Kripke's arguments goes the other way - that conclusions about reference and proper names were derived in part from controversial metaphysical assumptions about possible worlds and essential properties. | |
| From: comment on Saul A. Kripke (Naming and Necessity lectures [1970]) by Robert C. Stalnaker - Reference and Necessity Intro | |
| A reaction: Nathan Salmon is famous for charging Kripke with trying to get a metaphysics from a semantics, but this remark of Stalnaker's seems much more accurate. Kripke certainly assumes realism, and robust identity. |
| 5822 | The important cause is not between dubbing and current use, but between the item and the speaker's information [Evans on Kripke] |
| Full Idea: Kripke has mislocated the important causal relation, which lies between the item's states and doings and the speaker's body of information - not between the item's being dubbed with a name and the speaker's contemporary use of it. | |
| From: comment on Saul A. Kripke (Naming and Necessity lectures [1970]) by Gareth Evans - The Causal Theory of Names §I | |
| A reaction: This feels sort of right. I sympathise with the much more social view of matters like reference, which grows out of Wittgenstein's anti-private language claims. I'm not sure where 'causation' come into Evans's picture. |
| 17033 | We may refer through a causal chain, but still change what is referred to [Kripke] |
| Full Idea: There may be a causal chain from our use of the term 'Santa Claus' to a certain historical saint, but still children, when they use this, by this time probably do not refer to that saint. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 2) | |
| A reaction: This is quite a significant concession to critics of the causal theory. I take it that community agreement is much more significant for reference than the actual causal chain, which may be riddled with errors from beginning to end, and so isn't causal. |
| 4689 | Kripke makes reference a largely social matter, external to the mind of the speaker [Kripke, by McGinn] |
| Full Idea: Kripke's theory brought a social element into the function of language: a speaker is socially connected to others who may know far more than she does about the reference of her terms, and the mechanism of reference is now not in her mind, but is external. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Colin McGinn - The Making of a Philosopher Ch. 3 | |
| A reaction: Hence this theory of reference leads on to Putnam's 'wide content' and Twin Earth. I remain unconvinced. See ideas under 'Thought'. |
| 17504 | Kripke's theory is important because it gives a collective account of reference [Kripke, by Putnam] |
| Full Idea: What is important about Kripke's theory is not that the use of proper names is 'causal' - what is not? - but that the use of proper names is collective. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Hilary Putnam - Explanation and Reference II B | |
| A reaction: This is the best response to Kripke. Reference is achieved by thinkers and speakers, but it is also a team activity, as in the case of the elm, or of Amenhotep II. |
| 17035 | We refer through the community, going back to the original referent [Kripke] |
| Full Idea: It's in virtue of our connection with other speakers in the community, going back to the referent himself, that we refer to a certain man. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 2) | |
| A reaction: There may be two theories of reference getting tangled up here. Going back to the origin is one thing, and relying on the community is another. Do I always know who I am referring to? 'The funniest man in London'. |
| 16988 | Descriptive reference shows how to refer, how to identify two things, and how to challenge existence [Kripke, by PG] |
| Full Idea: Summary: in favour of the descriptive theory of names are it gives you a mechanism for doing the referring (and Mill doesn't), we can identify two descriptions if there is one referent, and it allows us to question the existence of a referent. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 1) by PG - Db (ideas) | |
| A reaction: If this problem is seen in terms of mental files (with labels and contents) this whole problem becomes a lot clearer. I take reference to be the action of a thinker, not a function of language. |
| 17029 | It can't be necessary that Aristotle had the properties commonly attributed to him [Kripke] |
| Full Idea: It is just not, in any intuitive sense of necessity, a necessary truth that Aristotle had the properties commonly attributed to him. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 2) | |
| A reaction: This replies to Searle's claim that to be Aristotle he must have a fair number of the properties. Even if Searle is right, you can hardly pick the properties out individually and claim they are necessary. Kripke pulls epistemology away from metaphysics. |
| 14893 | Rigid designation creates a puzzle - why do some necessary truths appear to be contingent? [Kripke, by Maciŕ/Garcia-Carpentiro] |
| Full Idea: Kripke's proposal that referential expressions like indexicals, demonstratives, proper names and natural kind terms are de jure rigid designators created a puzzle - it entails 'modal illusions', truths that are in fact necessary appear to be contingent. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970], p.143-4) by Maciŕ/Garcia-Carpentiro - Introduction to 'Two-Dimensional Semantics' 1 | |
| A reaction: They are identifying this puzzle as the source of the need for two-dimensional semantics. Kripke notes that rigid designators may have their reference fixed by non-rigid descriptions. |
| 20266 | It is essential that wise people learn to express their wisdom, possibly even as foolishness [Nietzsche] |
| Full Idea: It is not yet enough to prove a thing, one must seduce people to accept it or raise them up to it. That is why a knowledgeable person ought to learn to speak his wisdom: and often in such a way that it sounds like foolishness. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 330) | |
| A reaction: Kant comes to mind. He has needed endless exegesis by people who write better than him. Have there been even greater philosophers who couldn't express their wisdom at all? Cratylus, perhaps! |
| 20251 | Actions done for a purpose are least understood, because we complacently think it's obvious [Nietzsche] |
| Full Idea: Of all actions, the ones least understood are those undertaken for a purpose, no doubt because they have always passed for the most intelligible and are to our way of thinking the most commonplace. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 127) | |
| A reaction: You feel that Nietzsche is right about our stupendous lack of of self-knowledge, but then a bit of a panic ensues, because it is not clear what you are supposed to do about anything, particularly if we don't know why anyone else does anything. |
| 20271 | Beauty in art is the imitation of happiness [Nietzsche] |
| Full Idea: By beauty in art one always understands imitation of happiness. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 433) | |
| A reaction: I'm not sure how one goes about imitating happiness. One can replicate things that make us happy, like a nice landscape. But some beauty in art is also novel, and produces a new sort of happiness. Kandinsky. |
| 20230 | The very idea of a critique of morality is regarded as immoral! [Nietzsche] |
| Full Idea: Even to think of criticising morality, to consider morality as a problem, as problematic: what? was that not - is that not - immoral? | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], Pref 3) | |
| A reaction: Offering critiques of the value of morality and of truth are perhaps Nietzsche's greatest achievements. |
| 20234 | Morality prevents us from developing better customs [Nietzsche] |
| Full Idea: Morality acts to prevent the rise of new and better mores: it stupefies. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 019) | |
| A reaction: Note that he wants 'better' customs, and not just different ones. So the deep question concerns the criteria for why some customs are better. He seems to want us to fulfil our natures more completely. Arts, sciences, great deeds... |
| 20237 | Moral feelings are entirely different from the moral concepts used to judge actions [Nietzsche] |
| Full Idea: The history of moral feeling is completely different from the history of moral concepts. The former are powerful before, the latter especially after an action in view of the compulsion to pronounce upon it. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 034) | |
| A reaction: I think he places the feelings in our animal origins, and the concepts in rather unnatural cultures. |
| 20238 | Treating morality as feelings is just obeying your ancestors [Nietzsche] |
| Full Idea: To trust your feelings - that means obeying your grandfather and your grandmother and their grandparents more than the gods in us: our reason and our experience. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 035) | |
| A reaction: He says prior to this that feelings are just an inheritance, not our true natures. Stoics said 'live according to nature', by which they meant 'live by reason', because that is our true nature. |
| 20243 | Human beings are not majestic, either through divine origins, or through grand aims [Nietzsche] |
| Full Idea: Formerly one tried to get a feel for the majesty of human beings by pointing backward toward their divine descent: this has now become a forbidden path. ...So now the path humanity pursues is proof of its majesty. Alas, this too leads nowhere! | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 049) | |
| A reaction: I love the breadth of Nietzsche's vision, both across history, and in the great scheme. He goes on to say that we are no more a 'higher order' than ants and earwigs. |
| 20268 | Most dying people have probably lost more important things than what they are about to lose [Nietzsche] |
| Full Idea: The act of dying is not as significant as the universal awe of it would have us believe, and the dying person has probably lost more important things in life than he is now about to lose. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 349) | |
| A reaction: He says this is a thought about death which we tend to repress. It would depend on the life, I should think, but it is probably right in very many cases. |
| 20252 | Marriage is too serious to be permitted for people in love! [Nietzsche] |
| Full Idea: Lovers' vows ought to be publicly declared invalid and marriage denied the pair: and indeed precisely because one ought to take marriage unspeakably more seriously! | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 151) | |
| A reaction: Sounds like the traditional aristocratic attitude to marriage, so the idea suits Nietzsche. I think that nowadays it is much wiser to be base proposal of marriage on friendship than on love. You are choosing a life-long friend, not someone to adore. |
| 20236 | Marriage upholds the idea that love, though a passion, can endure [Nietzsche] |
| Full Idea: The institution of marriage stubbornly upholds the belief that love, though a passion, is, as such, capable of duration. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 027) | |
| A reaction: No wonder Nietzsche never married. Women must have been terrified of him, when he came out with this sort of remark. I doubt whether many couples who are celebrating their golden wedding would agree with him. [1/5/2017] |
| 20263 | Fear reveals the natures of other people much more clearly than love does [Nietzsche] |
| Full Idea: Fear has furthered the universal knowledge of humanity more than love, for fear wants to discern who the other person is, what he can do and what he wants. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 309) | |
| A reaction: Nietzsche had it in for love at this stage in his career. This remark strikes me as brilliantly accurate. |
| 20233 | Punishment has distorted the pure innocence of the contingency of outcomes [Nietzsche] |
| Full Idea: With this infamous art of interpreting the concept of punishment, people have robbed of its innocence the whole, pure contingency of events. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 013) | |
| A reaction: What a wonderfully subtle observation about moral luck! That whole problem is driven by the issue of whether the agent should be punished. When a chain of errors leads to disaster, we may see many innocent people doing a collective evil. |
| 20248 | People do nothing for their real ego, but only for a phantom ego created by other people [Nietzsche] |
| Full Idea: Whatever they say about their 'egotism', people nevertheless do nothing their whole life long for their ego, but instead for the phantom ego that has formed in the heads around them and been communicated to them. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 105) | |
| A reaction: Nietzsche has a vision of true devotion to the ego as healthy, and so (I would say) does Aristotle, though the two might disagree about the details. I want to live among people who work on themselves, not those who always sacrifice themselves. |
| 20246 | If you feel to others as they feel to themselves, you must hate a self-hater [Nietzsche] |
| Full Idea: Supposing we felt toward someone else as that person feels about himself, then we would have to hate him if he (like Pascal) found himself hateful. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 063) | |
| A reaction: And how does the Golden Rule work if the other people feel suicidal (as groups sometimes do)? |
| 20272 | Honesty is a new young virtue, and we can promote it, or not [Nietzsche] |
| Full Idea: Among neither the Socratic nor the Christian virtues does honesty appear: it is one of the youngest virtues, still quite immature. ...We can advance it or retard it, as we see fit. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 456) | |
| A reaction: I associate the virtue of honesty with the cult of sincerity of feelings which arose in the romantic movement. |
| 20240 | The Jews treated great anger as holy, and were in awe of those who expressed it [Nietzsche] |
| Full Idea: The Jews felt differently about wrath than we do and decreed it holy; in return, they, as a people, viewed the foreboding majesty of the individual with whom wrath showed itself connected, at a height at which a European is incapable of imagining. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 038) | |
| A reaction: If you thought wrath was really wonderful then presumably you would aspire to partake of it, but I see no signs of the Jews having been an especially wrathful people. It sounds like the tantrums of Tudor monarchs, which was their royal privilege. |
| 20244 | Christianity replaces rational philosophical virtues with great passions focused on God [Nietzsche] |
| Full Idea: Christianity disallows all moral value to the virtue of philosophers - the triumph of reason over affects - and demands that affects reveal themselves in splendour, as love of God, fear before God, fanatical faith in God, and blindest hope in God. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 058) | |
| A reaction: Faith, hope and charity are the three great Christian virtues that were added to the four cardinal virtues of the Greeks. |
| 20274 | The cardinal virtues want us to be honest, brave, magnanimous and polite [Nietzsche] |
| Full Idea: Honest towards ourselves and whatever else is our friend; courageous toward the enemy; magnanimous toward the defeated; polite - always. This is how the four cardinal virtues want us to be. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 556) | |
| A reaction: I take this to be Nietzsche genuinely asserting his four cardinal virtues, rather than being ironic. He certainly asserts politeness as the fourth virtue earlier in the book. Cf a different list in Idea 20382 |
| 20257 | Cool courage and feverish bravery have one name, but are two very different virtues [Nietzsche] |
| Full Idea: Courage as cold bravery and imperturbability, and courage as feverish, half-blind bravura - one calls both of these things by the same name! How different are the cold virtues from the warm ones! | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 277) | |
| A reaction: How few philosophers are capable of making a subtle but accurate observation like this! How many other virtues should be subdivided? |
| 20259 | Teach youth to respect people who differ with them, not people who agree with them [Nietzsche] |
| Full Idea: The surest way to ruin a youth is by teaching him to respect those who think like him more highly than those who think differently. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 297) | |
| A reaction: On the whole I prefer to read the philosophers who seem to be on my side, because I am trying to strengthen my explanation of the world, and opponents aren't much help. I do read opponents, if they explicitly challenge what I defend. |
| 20267 | Seeing duty as a burden makes it a bit cruel, and it can thus never become a habit [Nietzsche] |
| Full Idea: To require that duty always be somewhat burdensome - as Kant does - amounts to acquiring that it never become habit and custom: in this requirement there linger a tiny remnant of ascetic cruelty. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 339) | |
| A reaction: Habit, of course, is the ideal of Aristotelian virtue. |
| 20275 | Most people think they are already complete, but we can cultivate ourselves [Nietzsche] |
| Full Idea: We are free to handle and cultivate our drives like a gardener ...but how many people know we are free to do this? Don't most people believe in themselves as completed, full grown up facts? | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 560) | |
| A reaction: I see Nietzsche as an existentialist philosopher. He is much more than that, but this quotation endorses what I take to be the central idea of existentialism. |
| 20229 | No authority ever willingly accepts criticism [Nietzsche] |
| Full Idea: As long as the world has existed, no authority has ever willingly permitted itself to become the object of critique. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], Pref 3) | |
| A reaction: A political remark, but it leads into speaking of conventional morality as just such an authority. Nowadays teachers have feedback forms, and leaders have to endure party conferences. But on the whole it remains true. |
| 20254 | People govern for the pleasure of it, or just to avoid being governed [Nietzsche] |
| Full Idea: Some govern out of pleasure in governing, others in order not to be governed - to the latter, governing is merely the lesser of two evils. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 181) | |
| A reaction: Our current society is full of self-employed people whose major motivation is to avoid being employees. |
| 20273 | The French Revolution gave trusting Europe the false delusion of instant recovery [Nietzsche] |
| Full Idea: The 'Great Revolution' [in France] was nothing more than a pathetic and bloody quackery, which understood how, through sudden crises, to supply a trusting Europe with the sudden hope of recovery. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 534) | |
| A reaction: Whenever a new leader comes into power there is the same honeymoon period, where dreams of salvation have a moment in the sun. |
| 20232 | Get rid of the idea of punishment! It is a noxious weed! [Nietzsche] |
| Full Idea: People of diligence and goodwill, lend a hand in the one work of eradicating from the face of the earth the concept of punishment, which has overrun the whole world! There is no more noxious weed! | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 013) | |
| A reaction: Nietzsche never tried his hand at school teaching or parenting or running a youth club. But I still love this idea. In really good families I suspect that punishment is almost unknown. |
| 20253 | Modern wars arise from the study of history [Nietzsche] |
| Full Idea: The great wars of our day are the effects of the study of history. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 180) | |
| A reaction: The Prussians reacted to Napoleon. The Nazis reacted to Versailles. But now the study of history reveals to us dreadful wars based on simplistic accounts of history. Be wise about history, not ignorant of it. |
| 20261 | History does not concern what really happened, but supposed events, which have all the influence [Nietzsche] |
| Full Idea: The writer of history deals not with what really happened but merely with supposed events, for only the latter have had an effect. ...All historians speak of things that have never existed except in imagination. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 307) | |
| A reaction: This seems blatantly true, and is most obvious in the case of forged documents which have been hugely influential. Erroneous conspiracy theories are another example. (Note: only scorn conspiracy theories if you think conspiracies never happen!). |
| 17056 | Terms for natural kinds are very close to proper names [Kripke] |
| Full Idea: According to the view I advocate, terms for natural kinds are much closer to proper names than is ordinarily supposed. …'Common name' is appropriate for species …and also for certain mass terms such as 'gold' and 'water'. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) |
| 4963 | The properties that fix reference are contingent, the properties involving meaning are necessary [Kripke] |
| Full Idea: Bear in mind the contrast between the a priori but perhaps contingent properties carried with a natural kind term, given by the way its reference was fixed, and the analytic (and hence necessary) properties a term may carry, given by its meaning. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: The second half of this is the 'new essentialism'. Complex. We need to distinguish 'reference' from 'definition'. The 'analytic properties' seem to be the definition, but we sometimes change our definitions (e.g. of units of time). |
| 17053 | Gold's atomic number might not be 79, but if it is, could non-79 stuff be gold? [Kripke] |
| Full Idea: Gold could turn out not to have atomic number 79. …But given that gold does have the atomic number 79, could something be gold without having the atomic number 79? | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: The question seems to be 'is atomic number 79 essential to gold?', and on p.124 Kripke seems to say 'yes'. I agree. But how do we decide which features are essential to gold? Why do we think molten gold does count as gold? |
| 4964 | 'Cats are animals' has turned out to be a necessary truth [Kripke] |
| Full Idea: 'Cats are animals' has turned out to be a necessary truth. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: False! As Putnam has pointed out, we could yet discover that cats are subtly designed alien robots. This is a revealing error by Kripke, showing his desire to move from a useful logical clarification to an excessively amibitious metaphysics. |
| 6765 | Nominal essence may well be neither necessary nor sufficient for a natural kind [Kripke, by Bird] |
| Full Idea: Kripke's tiger example shows that a nominal essence is not necessary for the existence of a natural kind; examples from Putnam show that a nominal essence is not sufficient either. | |
| From: report of Saul A. Kripke (Naming and Necessity lectures [1970]) by Alexander Bird - Philosophy of Science Ch.3 | |
| A reaction: None of the characteristics of a tiger is essential to it. The appearance of water doesn't fix its reference. The move is towards an external view, that what matters for natural kinds is the real essence, not human conventions about it. I agree. |
| 9387 | The scientific discovery (if correct) that gold has atomic number 79 is a necessary truth [Kripke] |
| Full Idea: Scientific discoveries about what gold is are not contingent truths, but are necessary truths in the strictest possible sense. ..If scientists are right, then it will be necessary and not contingent that gold be an element with atomic number 79. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: I think this glorious and controversial claim is correct. It is hard to find supporting arguments, but the picture of nature that emerges (where the essences of the stuffs precede the laws of their behaviour) seems to me far more coherent. |
| 17054 | Scientific discoveries about gold are necessary truths [Kripke] |
| Full Idea: Statement representing scientific discoveries about what this stuff (gold) is are not contingent truths but necessary truths in the strictest possible sense. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: People take him to mean 'metaphysically necessary' here. How do we distinguish the 'scientific' discoveries, which are necessary, from the more casual discoveries, which may not be? Presumably being yellow is also necessary? |
| 17057 | Once we've found that heat is molecular motion, then that's what it is, in all possible worlds [Kripke] |
| Full Idea: We have discovered a phenomenon (heat) which in all possible worlds will be molecular motion - which could not have failed to be molecular motion, because that's what the phenomenon is. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: He refers to the identification as an 'essential property' of the phenomenon (and not merely a necessity). For my taste, Kripke uses the word 'property' too widely. |
| 19667 | If the laws of nature are contingent, shouldn't we already have noticed it? [Meillassoux] |
| Full Idea: The standard objection is that if the laws of nature were actually contingent, we would already have noticed it. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 4) | |
| A reaction: Meillassoux offers a sustained argument that the laws of nature are necessarily contingent. In Idea 19660 he distinguishes contingencies that must change from those that merely could change. |
| 19670 | Why are contingent laws of nature stable? [Meillassoux] |
| Full Idea: We must ask how we are to explain the manifest stability of physical laws, given that we take these to be contingent? | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 4) | |
| A reaction: Meissalloux offers a very deep and subtle answer to this question... It is based on the possibilities of chaos being an uncountable infinity... It is a very nice question, which physicists might be able to answer, without help from philosophy. |
| 4965 | Science searches basic structures in search of essences [Kripke] |
| Full Idea: Science attempts, by investigating basic structural traits, to find the nature, and thus the essence (in the philosophical sense) of the kind. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: The 'necessity' of essences should be treated with caution, but this account of science strikes me as right, with the inbuilt assumption that the 'laws' are the consequence of the essences. A regularity becomes a law when it is explained by an essence. |
| 20241 | Enquirers think finding our origin is salvation, but it turns out to be dull [Nietzsche] |
| Full Idea: Investigators of knowledge ...have regularly presupposed that the salvation of humanity depended on insight into the origin of things. ...but with insight into origin comes the increasing insignificance of origin. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 044) | |
| A reaction: This sounds like the etymological fallacy, of thinking that the origin of a word gives you a true grasp of its meaning. |
| 17050 | Tigers may lack all the properties we originally used to identify them [Kripke] |
| Full Idea: We might find out that tigers had none of the properties by which we originally identified them. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: This sounds like a can of worms. If I baptise someone 'the tallest man in the room', and it turns out he isn't, I withdraw my baptism. Why would I never withdraw 'tiger'? I suppose Kripke is right. |
| 17051 | The original concept of 'cat' comes from paradigmatic instances [Kripke] |
| Full Idea: The original concept of cat is: that kind of thing, where the kind can be identified by paradigmatic instances. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: Kripke evokes Putnam at this point, since he is famous for this proposal. Note that Kripke uses the plural, invoking more than one instance. Presumably we must abstract the fur colours from the instances? |
| 17049 | 'Tiger' designates a species, and merely looking like the species is not enough [Kripke] |
| Full Idea: We can say in advance that we use the term 'tiger' to designate a species, and that anything not of this species, even though it looks like a tiger, is not in fact a tiger. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: This is the 'baptismal' direct reference theory applied to species as well as to particular names. It seem to hinge on an internal structure being baptised, despite ignorance of what that structure is. Cf nominal essence? 'Tiger' denotes their essence? |
| 19653 | The ontological proof of a necessary God ensures a reality external to the mind [Meillassoux] |
| Full Idea: Since Descartes conceives of God as existing necessarily, whether I exist to think of him or not, Descartes assures me of a possible access to an absolute reality - a Great Outdoors that is not a correlate of my thought. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 2) | |
| A reaction: His point is that the ontological argument should be seen as part of the scientific revolution, and not an anomaly within it. Interesting. |
| 19658 | Now that the absolute is unthinkable, even atheism is just another religious belief (though nihilist) [Meillassoux] |
| Full Idea: Once the absolute has become unthinkable, even atheism, which also targets God's inexistence in the manner of an absolute, is reduced to a mere belief, and hence to a religion, albeit of the nihilist kind. | |
| From: Quentin Meillassoux (After Finitude; the necessity of contingency [2006], 2) | |
| A reaction: An interesting claim. Rather hard to agree or disagree, though the idea that atheism must qualify as a religion seems odd. If it is unqualified it does have the grand quality of a religion, but if it is fallibilist it just seems like an attitude. |
| 20245 | Christianity hoped for a short cut to perfection, that skipped the hard labour of morality [Nietzsche] |
| Full Idea: You can say what you like: Christianity wanted to liberate humanity from the burden of the demands of morality by pointing out a shorter way to perfection, or so it believed. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 059) | |
| A reaction: This conjures up Graham Greene's Catholic heroes, who wallow in sin, but hope for salvation at the last moment. |
| 20247 | Christianity was successful because of its heathen rituals [Nietzsche] |
| Full Idea: Not what is Christian in it, rather the universal heathenism of its rituals is the reason for the propagation of this world religion. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 070) | |
| A reaction: I'm afraid I think this is right. I grew up bewildered by the lack of content in the rituals of church services. Even austere protestants manage to sing and recite. Maybe philosophies should do this - wanted: new Cartesian and Kantian rituals! |
| 20269 | 'I believe because it is absurd' - but how about 'I believe because I am absurd' [Nietzsche] |
| Full Idea: Many people have achieved the humility that says: 'I believe because it is absurd', and have sacrificed their reason for it. But no one, as far as I know, has achieved the humility, which is only one step further, of 'I believe because I am absurd'. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 417) | |
| A reaction: Nietzsche gives the Latin: 'credo quia absurdum est' (Tertullian), and 'credo quia absurdus sum'. It may look like an insulting remark from Nietzsche, but it is actually in tune with the spirit of the original. |
| 20264 | The easy and graceful aspects of a person are called 'soul', and inner awkwardness is called 'soulless' [Nietzsche] |
| Full Idea: The sum of inner movements that are easy for a person and that he consequently performs happily and with grace is called his 'soul'; - if inner movements obviously cause him difficulty and effort, he is considered soulless. | |
| From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 311) | |
| A reaction: 'Soulless' is usually applied to people deficient in some sort of empathic feeling, or with an inability to recognise grandeur. It seems to imply that people who experience inner torture are soulless, but romantics see them as very soulful. |
