132 ideas
| 23350 | A wise philosophers uses reason to cautiously judge each aspect of living [Epictetus] |
| Full Idea: The sinews of a philosopher are desire that never fails in its achievement; aversion that never meets with what it would avoid; appropriate impulse; carefully considered purpose; and assent that is never precipitate. | |
| From: Epictetus (The Discourses [c.56], 2.08.29) | |
| A reaction: This is a very individual view of wisdom and the philosopher, whereas wisdom is often thought to have a social role. Is it not important for a philosopher to at least offer advice? |
| 23355 | The task of philosophy is to establish standards, as occurs with weights and measures [Epictetus] |
| Full Idea: Things are judged and weighed, when we have the standards ready. This is the task of philosophy: to examine and establish the standards. | |
| From: Epictetus (The Discourses [c.56], 2.11.24) | |
| A reaction: It is interesting that this gives philosophers a very specific social role, and also that it seems to identify epistemology as First Philosophy. Other disciplines, of course, establish their own standards without reference to philosophy. |
| 21394 | Philosophy is knowing each logos, how they fit together, and what follows from them [Epictetus] |
| Full Idea: [Philosophical speculation] consists in knowing the elements of 'logos', what each of them is like, how they fit together, and what follows from them. | |
| From: Epictetus (The Discourses [c.56], 4.08.14), quoted by A.A. Long - Hellenistic Philosophy 4.1 | |
| A reaction: [Said to echo Zeno] If you substitute understanding for 'logos' (plausibly), I think this is exactly the view of philosophy I would subscribe to. We want to understand each aspect of life, and we want those understandings to cohere with one another. |
| 20876 | Philosophy investigates the causes of disagreements, and seeks a standard for settling them [Epictetus] |
| Full Idea: The start of philosophy is perception of the mutual conflict among people, and a search for its cause, plus the rejection and distrust of mere opinion, an investigation to see if opinion is right, and the discovery of some canon, like scales for weighing. | |
| From: Epictetus (The Discourses [c.56], 2.11.13) | |
| A reaction: So the number one aim of philosophy is epistemological, to find the criterion for true opinion. But it starts in real life, and would cease to trade if people would just agree. I think we should set the bar higher than that. |
| 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. |
| 13099 | Analysing right down to primitive concepts seems beyond our powers [Leibniz] |
| Full Idea: An analysis of concepts such that we can reach primitive concepts...does not seem to be within human power. | |
| From: Gottfried Leibniz (Introduction to a Secret Encyclopaedia [1679], C513-14), quoted by Cover,J/O'Leary-Hawthorne,J - Substance and Individuation in Leibniz | |
| A reaction: Leibniz is nevertheless fully committed, I think, to the existence of such primitives, and is in the grip of the rationalist dream that thoughts can become completely clear, and completely well-founded. |
| 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. |
| 23344 | Reason itself must be compounded from some of our impressions [Epictetus] |
| Full Idea: What is reason itself? Something compounded from impressions of a certain kind. | |
| From: Epictetus (The Discourses [c.56], 1.20.05) | |
| A reaction: This seems to be the only escape from the dead end attempts to rationally justify reason. Making reason a primitive absolute is crazy metaphysics. |
| 23343 | Because reason performs all analysis, we should analyse reason - but how? [Epictetus] |
| Full Idea: Since it is reason that analyses and completes all other things, reason itself should not be left unanalysed. But by what shall it be analysed? ..That is why philosophers put logic first, just as when measuring grain we first examine the measure. | |
| From: Epictetus (The Discourses [c.56], 1.17.01) | |
| A reaction: The problem of the definitive metre rule in Paris. I say we have to test reason against the physical world, and the measure of reason is truth. Something has to be primitive, but reason is too vague for that role. Idea 23344 agrees with me! |
| 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. |
| 5022 | We hold a proposition true if we are ready to follow it, and can't see any objections [Leibniz] |
| Full Idea: A proposition is held to be true by us when our mind is ready to follow it and no reason for doubting it can be found. | |
| From: Gottfried Leibniz (Introduction to a Secret Encyclopaedia [1679], p.7) | |
| A reaction: This follows on from Descartes' view, but it now sounds more like psychology than metaphysics. Clearly a false proposition could fit this desciption. Personally I follow propositions to which I can see no objection, without actually holding them 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 |
| 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. |
| 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. |
| 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. |
| 23359 | We can't believe apparent falsehoods, or deny apparent truths [Epictetus] |
| Full Idea: It is impossible to assent to an apparent falsehood, or to deny an apparent truth. | |
| From: Epictetus (The Discourses [c.56], 3.07.15) | |
| A reaction: The way some philosophers write you would think that most beliefs just result from private whims or social fashion. That happens, of course, but most beliefs result from direct contact with reality. |
| 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. |
| 23356 | Self-evidence is most obvious when people who deny a proposition still have to use it [Epictetus] |
| Full Idea: It is about the strongest proof one could offer of a proposition being evident, that even he who contradicts it finds himself having to make use of it. | |
| From: Epictetus (The Discourses [c.56], 2.20.01) | |
| A reaction: Philosophers sometimes make fools of themselves by trying, by the use of elaborate sophistry, to demolish propositions which are self-evidently true. Don't be one of these philosophers! |
| 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? |
| 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. |
| 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. |
| 23329 | We make progress when we improve and naturalise our choices, asserting their freedom [Epictetus] |
| Full Idea: Progress is when any of you turns to his own faculty of choice, working at it and perfecting it, so as to bring it fully into harmony with nature; elevated, free, unrestrained, unhindered, faithful, self-respecting. | |
| From: Epictetus (The Discourses [c.56], 1.04.18) | |
| A reaction: [See also Disc.3.5.7] Rationality is the stoic concept of being in 'harmony with nature'. It appears (from reading Frede) that this may be the FIRST EVER reference to free will. Note the very rhetorical way in which it is presented. |
| 23330 | Freedom is making all things happen by choice, without constraint [Epictetus] |
| Full Idea: He is free for whom all things happen in accordance with his choice, and whom no one can constrain. | |
| From: Epictetus (The Discourses [c.56], 1.12.09) | |
| A reaction: The idea of 'free' will seems to have resulted from a wide extension of the idea of constraint, with global determinism lurking in the background. |
| 23342 | Freedom is acting by choice, with no constraint possible [Epictetus] |
| Full Idea: He is free for whom all things happen in accordance with his choice, and whom no one can constrain. | |
| From: Epictetus (The Discourses [c.56], 1.12.09) | |
| A reaction: Presumable this means that constraint is absolutely impossible, even by Zeus, and not just contingent possibility, when no one sees me raid the fridge. |
| 23332 | Zeus gave me a nature which is free (like himself) from all compulsion [Epictetus] |
| Full Idea: Zeus placed my good nature in my own power, and gave it to me as he has it himself, free from all hindrance, compulsion and restraint. | |
| From: Epictetus (The Discourses [c.56], 3.03.10) | |
| A reaction: Although Frede traces the origin of free will to the centrality of choice in moral life (and hence to the elevation of its importance), this remark shows that there is a religious aspect to it. Zeus is supreme, and obviously has free will. |
| 23331 | Not even Zeus can control what I choose [Epictetus] |
| Full Idea: You can fetter my leg, but not even Zeus himself can get the better of my choice. | |
| From: Epictetus (The Discourses [c.56], 1.01.23) | |
| A reaction: This is the beginnings of the idea of free will. It is based on the accurate observation that the intrinsic privacy of a mind means that no external force can be assured of controlling its actions. Epictetus failed to think of internal forces. |
| 23338 | You can fetter my leg, but not even Zeus can control my power of choice [Epictetus] |
| Full Idea: What are you saying, man? Fetter me? You will fetter my leg; but not even Zeus himself can get the better of my choice. | |
| From: Epictetus (The Discourses [c.56], 1.01.23) | |
| A reaction: This seems to be the beginning of the idea of 'absolute' freedom, which is conjured up to preserve perfect inegrity and complete responsibility. Obviously you can be prevented from doing what you choose, so this is not compatibilism. |
| 20875 | If we could foresee the future, we should collaborate with disease and death [Epictetus] |
| Full Idea: The philosophers are right to say that if the honorable and good person knew what was going to happen, he would even collaborate with disease, death and lameness. | |
| From: Epictetus (The Discourses [c.56], 2.10.05) | |
| A reaction: The 'philosophers' must be the earlier stoics, founders of his school. |
| 23347 | If I know I am fated to be ill, I should want to be ill [Epictetus] |
| Full Idea: If I really knew that it was ordained for me to be ill at this moment, I would aspire to be so. | |
| From: Epictetus (The Discourses [c.56], 2.06.10) | |
| A reaction: The rub, of course, is that it is presumably impossible to know what is fated. Book 2.7 is on divination. I don't see any good in a mortally ill person desiring, for that reason alone, to die. Rage against the dying of the light, I say. |
| 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? |
| 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. |
| 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. |
| 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. |
| 23325 | Epictetus developed a notion of will as the source of our responsibility [Epictetus, by Frede,M] |
| Full Idea: The notion of will in Epictetus is clearly developed to pinpoint the source of our responsibility for our actions and to identify precisely what it is that makes them our own doings. | |
| From: report of Epictetus (The Discourses [c.56]) by Michael Frede - A Free Will 3 | |
| A reaction: So the key move is that responsibility needs a 'source', rather than being a generalisation about how our actions arise. The next step is demand an 'ultimate' source, and this leads to the idea that this new will is 'free'. This will can be good or bad. |
| 20873 | Tragedies are versified sufferings of people impressed by externals [Epictetus] |
| Full Idea: Tragedies are nothing but the sufferings of people who are impressed by externals, performed in the right sort of meter. | |
| From: Epictetus (The Discourses [c.56], 1.04.26) | |
| A reaction: The externals are things like honour, position and wealth. Wonderfully dismissive! |
| 23364 | Homer wrote to show that the most blessed men can be ruined by poor judgement [Epictetus] |
| Full Idea: Did not Homer write to show us that the noblest, the strongest, the richest, the handsomest of men may nevertheless be the most unfortunate and wretched, if they do not hold the judgements that they ought to hold? | |
| From: Epictetus (The Discourses [c.56], 4.10.36) | |
| A reaction: This seems to be right. He clearly wrote about the greatest and most memorable events of recent times, but not just to record triumphs, because almost every hero (in the Iliad, at least) ends in disaster. |
| 23340 | We consist of animal bodies and god-like reason [Epictetus] |
| Full Idea: We have these two elements mingled within us, a body in common with the animals, and reason and intelligence in common with the gods. | |
| From: Epictetus (The Discourses [c.56], 1.03.03) | |
| A reaction: This is what I call Human Exceptionalism, but note that it doesn't invoke a Christian soul or spiritual aspect. This separation of reason goes back at least to Plato. High time we stopped thinking this way. Animals behave very sensibly. |
| 23358 | Every species produces exceptional beings, and we must just accept their nature [Epictetus] |
| Full Idea: In every species nature produces some exceptional being, in oxen, in dogs, in bees, in horses. We do not say to them 'Who are you?' It will tell you 'I am like the purple in the robe. Do not expect me to be like the rest, or find fault with my nature'. | |
| From: Epictetus (The Discourses [c.56], 3.01.23) | |
| A reaction: This idea began with Aristotle's 'great soul', and presumably culminates in Nietzsche, who fills in more detail. In the modern world such people are mostly nothing but trouble. |
| 23339 | I will die as becomes a person returning what he does not own [Epictetus] |
| Full Idea: When the time comes, then I will die - as becomes a person who gives back what is not his own. | |
| From: Epictetus (The Discourses [c.56], 1.01.32) | |
| A reaction: There is a tension between his demand that he have full control of his choices, and this humility that says his actual life is not his own. The things which can't be controlled, though, are 'indifferents' so life and death are indifferent. |
| 23345 | Don't be frightened of pain or death; only be frightened of fearing them [Epictetus] |
| Full Idea: It is not pain or death that is to be feared, but the fear of pain or death. | |
| From: Epictetus (The Discourses [c.56], 2.01.13) | |
| A reaction: These two cases are quite different, I would say. I'm much more frightened of pain than I am of the fear of pain, and the opposite view seems absurd. About death, though, I think this is right. Mostly I'm with Spinoza: think about life, not death. |
| 23357 | Knowledge of what is good leads to love; only the wise, who distinguish good from evil, can love [Epictetus] |
| Full Idea: Whoever has knowledge of good things would know how to love them; and how could he who cannot distinguish good things from evil still have to power to love? It follows that the wise man alone has the power to love. | |
| From: Epictetus (The Discourses [c.56], 2.22.03) | |
| A reaction: A rather heartwarming remark, but hard to assess for its truth. Evil people are unable to love? Not even love a cat, or their favourite car? We would never call someone wise if they lacked love. |
| 23363 | The evil for everything is what is contrary to its nature [Epictetus] |
| Full Idea: Where is the paradox if we say that what is evil for everything is what is contrary to its nature? | |
| From: Epictetus (The Discourses [c.56], 4.01.125) | |
| A reaction: A very Greek view. For humans, it must rely on the belief that human nature is essentially good. If I am sometimes grumpy and annoying, why is that not part of my nature? |
| 23328 | The essences of good and evil are in dispositions to choose [Epictetus] |
| Full Idea: The essence of the good is a certain disposition of our choice, and essence of evil likewise. | |
| From: Epictetus (The Discourses [c.56], 1.29.01) | |
| A reaction: This is the origin of Kant's famous view, that the only true good is a good will. This is the alternative to good character or good states of affairs as the good. It points towards the modern more legalistic view of morality, as concerning actions. |
| 23362 | All human ills result from failure to apply preconceptions to particular cases [Epictetus] |
| Full Idea: The cause of all human ills is that people are incapable of applying their general preconceptions to particular cases. | |
| From: Epictetus (The Discourses [c.56], 4.01.42) | |
| A reaction: I'm not sure whether 'preconceptions' is meant pejoratively (as unthinking, and opposed to true principles). This sounds like modern particularism (e.g. Jonathan Dancy) to the letter. |
| 23353 | We have a natural sense of honour [Epictetus] |
| Full Idea: What faculty do you mean? - Have we not a natural sense of honour? - We have. | |
| From: Epictetus (The Discourses [c.56], 2.10.22) | |
| A reaction: This seems unlikely, given the lower status that honour now has with us, compared to two hundred years ago. But there may be a natural sense of status, and of humiliation and shame. |
| 23354 | If someone harms themselves in harming me, then I harm myself by returning the harm [Epictetus] |
| Full Idea: Since he has harmed himself by wronging me, shall not I harm myself by harming him? | |
| From: Epictetus (The Discourses [c.56], 2.10.26) | |
| A reaction: I am very keen on this idea. See Hamlet's remarks to Polonius about 'honour and dignity'. The best strategy for achieving moral excellence is to focus on our own characters, rather than how to act, and to respond to others. |
| 23324 | In the Discourses choice [prohairesis] defines our character and behaviour [Epictetus, by Frede,M] |
| Full Idea: In Epictetus's 'Discourses' the notion of choice [prohairesis] plays perhaps the central role. It is our prohairesis which defines us a person, as the sort of person we are; it is our prohairesis which determines how we behave. | |
| From: report of Epictetus (The Discourses [c.56]) by Michael Frede - A Free Will 3 | |
| A reaction: Frede is charting the gradual move in Greek philosophy from action by desire, reason and habit to action by the will (which then turns out to be 'free'). Character started as dispositions and ended as choices. |
| 23361 | Health is only a good when it is used well [Epictetus] |
| Full Idea: Is health a good and sickness an evil? No. Health is good when used well, and bad when used ill. | |
| From: Epictetus (The Discourses [c.56], 3.20.04) | |
| A reaction: Although I like the idea that health is a natural value, which bridges the gap from facts to values (as a successful function), there is no denying that the health of very evil people is not something the rest of us hope for. |
| 23346 | A person is as naturally a part of a city as a foot is part of the body [Epictetus] |
| Full Idea: Just as the foot in detachment is no longer a foot, so you in detachment are not longer a man. For what is a man? A part of a city, first. | |
| From: Epictetus (The Discourses [c.56], 2.05.26) | |
| A reaction: It is, of course, not true that a detached foot ceases to be a foot (and an isolated human is still a human). This an extreme version of the Aristotelian idea that we are essentially social. It is, though, the sort of view favoured by totalitarianism. |
| 23351 | We are citizens of the universe, and principal parts of it [Epictetus] |
| Full Idea: You are a citizen of the universe, and a part of it; and no subservient, but a principal part of it. | |
| From: Epictetus (The Discourses [c.56], 2.10.03) | |
| A reaction: He got this view from Diogenes of Sinope, one of his heroes. What community you are a part of seems to be a choice as much as a fact. Am I British or a European? |
| 20874 | A citizen is committed to ignore private advantage, and seek communal good [Epictetus] |
| Full Idea: The commitment of the citizen is to have no private advantage, not to deliberate about anything as though one were a separate part. | |
| From: Epictetus (The Discourses [c.56], 2.10.04) | |
| A reaction: This is the modern problem of whether democratic voters are choosing for themselves or for the community. I think we should make an active effort at every election to persuade voters to aim for the communal good. Cf Rawls. |
| 23352 | A citizen should only consider what is good for the whole society [Epictetus] |
| Full Idea: The calling of a citizen is to consider nothing in terms of personal advantage, never to deliberate on anything as though detached from the whole, but be like our hand or foot. | |
| From: Epictetus (The Discourses [c.56], 2.10.04) | |
| A reaction: Fat chance of that in an aggressively capitalist society. I've always voted for what I thought was the common good, and was shocked to gradually realise that many people only vote for what promotes their own interests. Heigh ho. |
| 22604 | Punishing a criminal for moral ignorance is the same as punishing someone for being blind [Epictetus] |
| Full Idea: You should ask 'Ought not this man to be put to death, who is deceived in things of the greatest importance, and is blinded in distinguishing good from evil?' …You then see how inhuman it is, and the same as 'Ought not this blind man to be put to death?' | |
| From: Epictetus (The Discourses [c.56], 1.18.6-7) | |
| A reaction: This is the doctrine of Socrates, that evil is ignorance (and weakness of will [akrasia] is impossible). Epictetus wants us to reason with the man, but what should be do if reasoning fails and he persists in his crimes? |
| 23349 | Asses are born to carry human burdens, not as ends in themselves [Epictetus] |
| Full Idea: An ass is surely not born as an end in itself? No, but because we had need of a back that is able to carry burdens. | |
| From: Epictetus (The Discourses [c.56], 2.08.07) | |
| A reaction: This is the absurd human exceptionalism which plagues our thinking. It would be somewhat true of animals which are specifically bred for human work, such as large cart horses. |
| 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). |
| 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. |
| 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? |
| 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. |
| 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. |
| 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. |
| 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? |
| 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? |
| 23341 | God created humans as spectators and interpreters of God's works [Epictetus] |
| Full Idea: God has introduced man into the world as a spectator of himself and of his works: and not only as a spectator of them, but an interpreter of them as well. | |
| From: Epictetus (The Discourses [c.56], 1.06.19) | |
| A reaction: This idea (which strikes me as bizarre) was picked up directly by the Christians. I can't imagine every Johnson wanting to creating their own Boswell. If you think we are divinely created, you have to propose some motive for it, I suppose. |
| 23348 | Both god and the good bring benefits, so their true nature seems to be the same [Epictetus] |
| Full Idea: God brings benefits; but the good also brings benefit. It would seem, then, that where the true nature of god is, there too is the true nature of good. | |
| From: Epictetus (The Discourses [c.56], 2.08.01) | |
| A reaction: An enthymeme, missing the premise that there can only be one source of benefit (which sounds unlikely). Does god bring anything other than benefits? And does the good? I think this is an idea from later platonism. |
| 23360 | Each of the four elements in you is entirely scattered after death [Epictetus] |
| Full Idea: Whatever was in you of fire, departs into fire; what was of earth, into earth; what of air, into air; what of water, into water. There is no Hades, nor Acheron. | |
| From: Epictetus (The Discourses [c.56], 3.13.15) | |
| A reaction: This sort of remark may explain why so few of the great Stoic texts (such as those of Chrysippus) survived the Christian era. |
