| 2945 | Most philosophers start with reality and then examine knowledge; Descartes put the study of knowledge first [Lehrer] |
| Full Idea: Some philosophers (e.g Plato) begin with an account of reality, and then appended an account of how we can know it, ..but Descartes turned the tables, insisting that we must first decide what we can know. | |
| From: Keith Lehrer (Theory of Knowledge (2nd edn) [2000], I p.2) |
| 2946 | You cannot demand an analysis of a concept without knowing the purpose of the analysis [Lehrer] |
| Full Idea: An analysis is always relative to some objective. It makes no sense to simply demand an analysis of goodness, knowledge, beauty or truth, without some indication of the purpose of the analysis. | |
| From: Keith Lehrer (Theory of Knowledge (2nd edn) [2000], I p.7) | |
| A reaction: Your dismantling of a car will go better if you know what a car is for, but you can still take it apart in ignorance. |
| 5831 | The new view is that "water" is a name, and has no definition [Schwartz,SP] |
| Full Idea: Perhaps the modern view is best expressed as saying that "water" has no definition at all, at least in the traditional sense, and is a proper name of a specific substance. | |
| From: Stephen P. Schwartz (Intro to Naming,Necessity and Natural Kinds [1977], §III) | |
| A reaction: This assumes that proper names have no definitions, though I am not clear how we can grasp the name 'Aristotle' without some association of properties (human, for example) to go with it. We need a definition of 'definition'. |
| 5829 | We refer to Thales successfully by name, even if all descriptions of him are false [Schwartz,SP] |
| Full Idea: We can refer to Thales by using the name "Thales" even though perhaps the only description we can supply is false of him. | |
| From: Stephen P. Schwartz (Intro to Naming,Necessity and Natural Kinds [1977], §III) | |
| A reaction: It is not clear what we would be referring to if all of our descriptions (even 'Greek philosopher') were false. If an archaeologist finds just a scrap of stone with a name written on it, that is hardly a sufficient basis for successful reference. |
| 5830 | The traditional theory of names says some of the descriptions must be correct [Schwartz,SP] |
| Full Idea: The traditional theory of proper names entails that at least some combination of the things ordinarily believed of Aristotle are necessarily true of him. | |
| From: Stephen P. Schwartz (Intro to Naming,Necessity and Natural Kinds [1977], §III) | |
| A reaction: Searle endorses this traditional theory. Kripke and co. tried to dismiss it, but you can't. If all descriptions of Aristotle turned out to be false (it was actually the name of a Persian statue), our modern references would have been unsuccessful. |
| 14348 | An 'antidote' allows a manifestation to begin, but then blocks it [Corry] |
| Full Idea: An 'antidote' (or 'mask') to a disposition (unlike a 'finkish' one) leaves the disposition intact, but interferes with the causal chain between the disposition and its manifestation so that the manifestation doesn't come about. | |
| From: Richard Corry (Dispositional Essentialism Grounds Laws of Nature? [2010], 2) | |
| A reaction: [He cites Bird 1997] Thus the disposition of the poison at least begins to manifest, but its disposition to kill is blocked. So what was the disposition of the poison? |
| 14347 | A 'finkish' disposition is one that is lost immediately after the appropriate stimulus [Corry] |
| Full Idea: An object's disposition is said to be 'finkish' if the object loses the disposition after the occurrence of the appropriate stimulus, but before the manifestation has had time to come about. | |
| From: Richard Corry (Dispositional Essentialism Grounds Laws of Nature? [2010], 2) | |
| A reaction: [He cites Lewis 1997] An example would be some sort of safety device which only cuts in if the disposition seems about to operate (e.g. turns off electricity). It seems to block analyses of dispositions simply in terms of their outcomes. |
| 14350 | If a disposition is never instantiated, it shouldn't be part of our theory of nature [Corry] |
| Full Idea: If we have no good reason to believe that a disposition is instantiated, then the disposition should play no role in our theorizing about the world. | |
| From: Richard Corry (Dispositional Essentialism Grounds Laws of Nature? [2010], 3) | |
| A reaction: It is part of our theory that a substantial lump of uranium will explode, but also that a galaxy-sized lump of uranium would explode. Surely we are committed to the latter, even though it never happens? |
| 14351 | Maybe an experiment unmasks an essential disposition, and reveals its regularities [Corry] |
| Full Idea: The dispositional essentialist can argue that what happens in laboratory conditions is that, by controlling external influences, we effectively 'unmask' the relevant dispositions, and thus observe the regularities to which those dispositions give rise. | |
| From: Richard Corry (Dispositional Essentialism Grounds Laws of Nature? [2010], 5) | |
| A reaction: That seems to me to be exactly right, though Corry dislikes it, and even suggests that dispositional essentialist might not like it. |
| 5826 | The intension of "lemon" is the conjunction of properties associated with it [Schwartz,SP] |
| Full Idea: The conjunction of properties associated with a term such as "lemon" is often called the intension of the term "lemon". | |
| From: Stephen P. Schwartz (Intro to Naming,Necessity and Natural Kinds [1977], §II) | |
| A reaction: The extension of "lemon" is the set of all lemons. At last, a clear explanation of the word 'intension'! The debate becomes clear - over whether the terms of a language are used in reference to ideas of properties (and substances?), or to external items. |
| 14346 | Dispositional essentialism says fundamental laws of nature are strict, not ceteris paribus [Corry] |
| Full Idea: Dispositional essentialism implies that the fundamental laws of nature must be strict, not ceteris paribus. | |
| From: Richard Corry (Dispositional Essentialism Grounds Laws of Nature? [2010], 1) | |
| A reaction: I am not keen on the 'laws' of nature, but since essentialism seems to make them necessary, you can't get stricter than that. |
