| 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. |
| 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. |
| 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. |
| 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. |
| 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? |
| 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. |
| 20589 | Maybe a person's true self is their second-order desires [Tuckness/Wolf] |
| Full Idea: A second-order desire is a desire about what kind of desires you want to have. ....Some philosophers have argued that we should associate a person's second-order desires with her 'true self'. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 2 'What is') | |
| A reaction: Presumably the buck stops at these second-order desires, though we might request an account of their origin. 'What sort of person do I want to be?' looks like a third-order question. I don't even want to be a saint. Self is nothing to do with desires? |
| 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. |
| 468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
| Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
| From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
| 20583 | If maximising pleasure needs measurement, so does fulfilling desires [Tuckness/Wolf] |
| Full Idea: Just as hedonists need a way to compare pleasures, so desire fulfilment theorists need a way to compare the fulfilment of desires. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 1 'Is happiness') | |
| A reaction: A nice point. We picture desire fulfilment as just ticking it off when it is achieved, but if your desire is for a really nice house, the achievement of that can be pretty vague. |
| 20584 | Desire satisfaction as the ideal is confused, because we desire what we judge to be good [Tuckness/Wolf] |
| Full Idea: Critics of desire satisfaction theory argue that it gets things backward. We desire things because we already think they are good in some way. Desire theory puts it the other way round. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 1 'Is happiness') | |
| A reaction: Not persuasive. It looks to me as if skiing is a spendid pastime, but I have no desire to do it. More exercise would even be a good for me, but I don't desire that either. Indeed, right now I desire more cake, which is very naughty. |
| 20598 | In a democracy, which 'people' are included in the decision process? [Tuckness/Wolf] |
| Full Idea: In any democratic state, who are 'the people' who get to rule themselves? That is, who gets to participate in the public decision process, and who is excluded? | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'What is') | |
| A reaction: In the modern world this may be clear-cut when a democracy gets started, but people move around so much more that every democracy is faced with new types of residents. Then there is age, criminality, mental health... |
| 20614 | People often have greater attachment to ethnic or tribal groups than to the state [Tuckness/Wolf] |
| Full Idea: Some states have a number of different ethnic or tribal groups. Often these attachments are much stronger than the attachment people feel towards the state. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 6 'Membership') | |
| A reaction: In Britain I fine people torn between attachments to the UK and to England or Wales or Scotland or NI. Attachments to football clubs are much stronger than most patriotism. Or attachment to a particular locality. Does it matter? |
| 20596 | For global justice, adopt rules without knowing which country you will inhabit [Tuckness/Wolf] |
| Full Idea: Imagine a new original position where we adopted rules for global justice without knowing which country we would inhabit. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 4 'Cosmopolitan') | |
| A reaction: Nice question. North Korea!! Rawls says it is only within a nation, because there is a co-operative enterprise going on. That is, I presume, that the choosers involved are a 'people'. See Kant's 'Perpetual Peace' for an alternative. |
| 20593 | The veil of ignorance ensures both fairness and unanimity [Tuckness/Wolf] |
| Full Idea: The veil of ignorance ensures that the original position is fair, but it also guarantees that agreement will be unanimous (which would be impossible if each person insisted that justice should match her own conception). | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 4 'Original') | |
| A reaction: Not clear about this. If I choose very cautiously, but others choose very riskily, and they win, why I should I fall in with their unanimity? That can only be if we agree to be unanimous in backing the result. Like a democratic election? |
| 20608 | Unjust institutions may be seen as just; are they legitimate if just but seen as unjust? [Tuckness/Wolf] |
| Full Idea: Legitimacy and perceived legitimacy do not always go together: people can believe that their institutions are just, but they may be wrong. Is the reverse also possible? Can institutions be legitimate if people believe they are not? | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'What are') | |
| A reaction: Nice thoughts. An institution cannot be just merely because it is seen that way (if someone gets away with rigging an election). If they are just but seen as unjust, I presume they are legitimate (which is objective), but disfunctional. |
| 20597 | If winning elections depends on wealth, we have plutocracy instead of democracy [Tuckness/Wolf] |
| Full Idea: If we let people's influence on election outcomes depend on their wealth, then we don't have a democracy any more. We have a plutocracy, where the people who have all the wealth have all the political power too. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Intro') | |
| A reaction: [see Michael Walzer on 'complex equality'] This is startling true in the United States, but still somewhat true elsewhere. Being wealthy enough to control the media is the key in modern democracies. |
| 20606 | Epistemic theories defend democracy as more likely to produce the right answer [Tuckness/Wolf] |
| Full Idea: According to epistemic theories of democracy, democratic outcomes are justified because they are more likely to be true or right than the choice of the individual. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Do the people') | |
| A reaction: Bear in mind Condorcet's proof that this claim is only correct if individuals have a better than 50% chance of being right, which may be so on obvious things, but is implausible for decisions like going to war. |
| 20600 | Which areas of public concern should be decided democratically, and which not? [Tuckness/Wolf] |
| Full Idea: Are there areas which are excluded from democratic decision making? Or should all issues of public concern be decided through a democratic process? | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'What is') | |
| A reaction: Crucially, are we discussing direct democracy, or representative democracy? In Britain all major decisions are made by the cabinet. Our representatives appoint leaders, who then appoint the decision makers. Judiciary is non-democratic. |
| 20609 | If several losing groups would win if they combine, a runoff seems called for [Tuckness/Wolf] |
| Full Idea: It is possible that the people who supported several losing candidates might have joined forces and had a majority. For that reason, many countries have a runoff election. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Does democracy') | |
| A reaction: The problem is that there is no rationale as to who stands in an election. If their views are evenly spread, the first result seems OK. If there are five left-wingers and one right-winger, a runoff seems to be produce a more just result. |
| 20605 | Rights as interests (unlike rights as autonomy) supports mandatory voting [Tuckness/Wolf] |
| Full Idea: If rights concern people's interests, that might support mandatory voting, but if rights rely on protecting autonomy that might oppose it. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Interest') | |
| A reaction: I approach it from the other end, and am inclined to support mandatory voting, which suggests I am more concerned about interests than about autonomy. |
| 20599 | How should democratic votes be aggregated? Can some person's votes count for more? [Tuckness/Wolf] |
| Full Idea: A major question for democracy is how are the contributions of different people aggregated into a collective decision? Must votes have equal weight and consideration, or is it permissible for different people's votes to count differently? | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'What is') | |
| A reaction: Mill hoped that wise and knowledgeable people would have a strong influence over the others, but we have recently moved into the post-truth era, where we are swamped by bogus facts. Does that strengthen the case for elite voting? |
| 20601 | Discussion before voting should be an essential part of democracy [Tuckness/Wolf] |
| Full Idea: According to advocates of deliberative democracy, people should have an opportunity to talk and reason with one another before votes are cast. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Who gets') | |
| A reaction: This is now done on Facebook and Twitter, but no one thinks that is sufficient. We will never again persuade most people to actually meet up and discuss issues. |
| 20613 | We have obligations to our family, even though we didn't choose its members [Tuckness/Wolf] |
| Full Idea: Many of our most important obligations are things we did not consent to. If you think you have obligations to your family, did you choose to have them as family members? | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 6 'Gratitude') | |
| A reaction: A question that gets close to the heart of the communitarian ideal, I think. We choose to have children, and we bring them up, but even then we don't choose who our children are. |
| 20586 | Free speech does not include the right to shout 'Fire!' in a crowded theatre [Tuckness/Wolf] |
| Full Idea: Oliver Wendell Holmes (in 1919) noted that freedom of speech does not include the right to shout 'Fire!' in a crowded theatre. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 1 'Conflict') | |
| A reaction: The point here is that such irresponsible free speech does not even require legislation, and there is probably already some law under which the perpetrator could be prosecuted. |
| 20587 | Most people want equality because they want a flourishing life [Tuckness/Wolf] |
| Full Idea: If we want equality so much, we find that it is often because they think of equality as a prerequisite for a certain kind of flourishing life. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 1 'Happiness') | |
| A reaction: Most writers seem to agree that we don't want equality for its own sake. In what respects do we want to be equal? Why not equal in hair colour? Hence it looks as if equality drops out. I would aim to derive it from the social virtue of respect. |
| 20591 | If there is no suffering, wealth inequalities don't matter much [Tuckness/Wolf] |
| Full Idea: It is hard to get worked up over wealth inequalities if no one is suffering from them! | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 3 'Deprivation') | |
| A reaction: The more the poorer group resent the inequality, the more they suffer. When is resenting huge inequalities in wealth justified? It depends how the big wealth was obtained. |
| 20602 | Some rights are 'claims' that other people should act in a certain way [Tuckness/Wolf] |
| Full Idea: A 'claim right' is one in which the person asserting the right makes a claim on others to act or not act in a certain way. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Claim') | |
| A reaction: There seems to be a crucial distinction between rights which entail obligations on some individual or institution, and those which don't. Contracts (including employment contracts) generate duties on the parties. |
| 20604 | Choice theory says protecting individual autonomy is basic (but needs to cover infants and animals) [Tuckness/Wolf] |
| Full Idea: Choice theorists hold that rights protect our rights to make autonomous judgements, because our basic right to autonomy must be protected, The theory has a problem with people unable to exercise autonomy (such as infants and animals). | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Interest') | |
| A reaction: The problem of infants and animals looks like a decisive objection to me. We obviously don't protect dangerous or hostile autonomous judgements, and it is not clear why protecting stupid autonomy should be basic. |
| 20603 | One theory (fairly utilitarian) says rights protect interests (but it needs to cover trivial interests) [Tuckness/Wolf] |
| Full Idea: Interest theorists hold that rights serve to protect people's important interests. This is closely allied with utilitarian values. The theory has difficulty accounting for relatively trivial interests (like owning a lemonade you bought). | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Interest') | |
| A reaction: This sounds more plausible than choice theory (Idea 20604). It is obvious that infants must have rights. The lemonade problem seems to demand some sort of rule utilitarianism. Sidgwick looks promising. Rights can also be moral claims. |
| 20607 | Having a right does not entail further rights needed to implement it [Tuckness/Wolf] |
| Full Idea: Possession of a right (such as self-defence) does not always imply that one has additional rights to whatever they need (such as a handgun) in order to exercise the first right. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Is there') | |
| A reaction: The right to life entails a right to food (but not to a banquet), so it is a stronger right than self-defence. I have no obligation to let you defend yourself against me, but I may have an obligation to feed you if you are starving. (Distinction here?) |
| 20612 | If being subject to the law resembles a promise, we are morally obliged to obey it [Tuckness/Wolf] |
| Full Idea: One of the more common reasons people will give for having a moral obligation to obey the law is consent. ...It rests on the intuitively appealing idea of an analogy with a promise. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 6 'Consent') | |
| A reaction: [They cite Locke and Jefferson] In Locke's case it has to be a 'tacit' promise, which is more realistic. In real life we have problems with people who 'said' they would do something. They are often accused of promising, when they didn't. |
| 20611 | If others must obey laws that we like, we must obey laws that they like? [Tuckness/Wolf] |
| Full Idea: If we expect others to obey the laws we think just, do we have an obligation to obey the laws that other people think just? | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 6 'What should') | |
| A reaction: Depends whether you have to be consistent about everything. I'm picky about which laws I obey, but I'm not going to tell you that, in case you get the same idea. Free riders. |
| 20610 | Instead of against natural law, we might assess unjust laws against the values of the culture [Tuckness/Wolf] |
| Full Idea: Do we need natural law theory in order to make sense of the idea that laws can be unjust? Perhaps not: we might consider whether laws are consistent with the values of the culture or society where they apply. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 5 'Unjust') | |
| A reaction: So were the wicked laws passed by the Nazis consistent with 1930s German culture? Impossible to say. |
| 20617 | How should the punishment fit the crime (for stealing chickens?) [Tuckness/Wolf] |
| Full Idea: One criticism of the retributive theory of punishment is that it is hard to know how to fit the punishment to the crime. What punishment should correspond to stealing chickens? | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 7 'Rationales') | |
| A reaction: The ancient world was more keen on restitution for such crimes, which makes much better sense. Buy them some chickens, plus twenty percent. |
| 20615 | Just wars: resist aggression, done on just cause, proportionate, last resort, not futile, legal [Tuckness/Wolf] |
| Full Idea: Classical just war theory: resist aggression; just cause must be the real reason; must be proportionate; last resort; not futile; made by a nation's authority. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 9 'Ius ad') | |
| A reaction: [My squashed summary of Tuckness and Wolf] A very helpful list, from Cicero, Augustine and Aquinas. So where is the sticking point for pacifists? Presumably it is never the last resort, and aggression should not answer aggression. |
| 20616 | During wars: proportional force, fair targets, fair weapons, safe prisoners, no reprisals [Tuckness/Wolf] |
| Full Idea: Classical just war theory during a war: force must be proportional; only legitimate targets; avoid prohibited weapons; safety for prisoners of war; no reprisals. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 9 'In the conduct') | |
| A reaction: What of massacre if a besieged city refuses to surrender? It was commonplace, and sometimes the only way to achieve victory. What if the enemy breaks all the rules? Nice rules though. At the heart of civilisation. |
| 20620 | If minority views are accepted in debate, then religious views must be accepted [Tuckness/Wolf] |
| Full Idea: It is unfair to exclude religious arguments from the public square because they are not accepted by everyone, unless other views that are not accepted by everyone are also excluded. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 9 'fairly') | |
| A reaction: Raises the obvious problems of a huge group in the grips of a fairly crazy view, and a tiny group (e.g. specialist scientists) in possession of a correct view. You can't just assess it on the size of the group. You can be wrong but reasonable. |
| 20619 | Is abortion the ending of a life, or a decision not to start one? [Tuckness/Wolf] |
| Full Idea: One group may consider abortion as a decision to end a life, while another may regard it as the decision not to start one. | |
| From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 8 'Hard I') | |
| A reaction: An early foetus is 'life', but is it 'a life'? Is a blade of grass 'a life'? Is a cell in a body 'a life'? |
| 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. |
| 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. |
| 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? |
