| 13583 | There might be uninstantiated natural kinds, such as transuranic elements which have never occurred [Ellis] |
| Full Idea: There are reasons to believe that there are natural kinds that might never be instantiated, such as a transuranic element, capable of existing for some fraction of a second, but which has never actually existed anywhere. | |
| From: Brian Ellis (Scientific Essentialism [2001], 2.05) | |
| A reaction: He cautiously claims that kinds are ontologically prior to their individual members. I would say that there is no natural kind of the type that he describes. He says you have at least some grounds for predicting what kinds are possible. |
| 13574 | Natural kinds are distinguished by resting on essences [Ellis] |
| Full Idea: Natural kinds are distinguished from other sorts of things by their associations with essential properties and real essences. | |
| From: Brian Ellis (Scientific Essentialism [2001], 1.02) | |
| A reaction: I don't think I agree with this. I rest my notion of natural kind on the elementary realising that to know all about this kind you only have to examine one sample of it, as in the Upanishads. The source of such a phenomenon is an open question. |
| 15150 | The properties of an electron can't be explained just as 'clustering' [Chakravartty on Boyd] |
| Full Idea: Boyd's homeostatic mechanisms are not responsible for the co-instantiation of the mass, charge and spin of an electron. | |
| From: comment on Richard Boyd (Homeostasis, Species and Higher Taxa [1999]) by Anjan Chakravarrty - Inessential Aristotle: Powers without Essences 3 | |
| A reaction: I would have thought that no one has the foggiest idea (unless I have missed something?) about why electrons have those three properties. What is it about electrons that makes them do that? Explanations always run out somewhere. Substratum! |
| 15149 | Properties cluster together, either because of intrinsic relations, or because of an underlying process [Boyd, by Chakravartty] |
| Full Idea: Boyd analyses 'sociability' between properties in terms of 'homeostasis', as causal relations between properties that favour clustering, or underlying processes that favour coinstantiation, or both. | |
| From: report of Richard Boyd (Homeostasis, Species and Higher Taxa [1999]) by Anjan Chakravarrty - Inessential Aristotle: Powers without Essences 3 | |
| A reaction: Chakravarty criticises this claim, by Boyd is clearly onto something. If, like me, you think natural kinds are overrated, you have to like his view. |
| 13575 | If there are borderline cases between natural kinds, that makes them superficial [Ellis] |
| Full Idea: There cannot be any borderline cases between the real essences of different natural kinds because, if there were, the distinctions between the kinds would be superficial, like the blue/green distinction. | |
| From: Brian Ellis (Scientific Essentialism [2001], 1.05) | |
| A reaction: His particular target here is biological natural kinds, in which he doesn't believe, because they blur across time, in the evolutionary process. Personally I am inclined to relax the notion of a natural kind, otherwise they are too basic to explain. |
