15990 | Every individual thing which exists has an essence, which is its internal constitution [Locke] |
Full Idea: I take essences to be in everything that internal constitution or frame for the modification of substance, which God in his wisdom gives to every particular creature, when he gives it a being; and such essences I grant there are in all things that exist. | |
From: John Locke (Letters to Edward Stillingfleet [1695], Letter 1), quoted by Simon Blackburn - Quasi-Realism no Fictionalism | |
A reaction: This is the clearest statement I have found of Locke's commitment to essences, for all his doubts about whether we can know such things. Alexander says (ch.13) Locke was reacting against scholastic essence, as pertaining to species. |
11993 | Jones may cease to exist without some simple property, but that doesn't make it essential [Kung] |
Full Idea: If Jones ceases to be a father, or ceases to be over eight years old, he will cease to exist, yet these properties surely do not belong essentially to him. | |
From: Joan Kung (Aristotle on Essence and Explanation [1977], II) | |
A reaction: This seems to correct, though I would doubt whether either of these count as true properties, in the causal sense I prefer. If being 'over 8' is a property, how many 'over n' or 'under m' properties does he have? One for each quantum moment? |
11997 | A property may belong essentially to one thing and contingently to another [Kung] |
Full Idea: It is possible that a property may belong essentially to one thing and contingently to another. | |
From: Joan Kung (Aristotle on Essence and Explanation [1977], III) | |
A reaction: Thus a love of blues music may be part of your essence, but only a minor part of me. Sounds right. Spin or charge are part of the essence of an electron, but only contingently part of a child's top. |
11992 | Aristotelian essences underlie a thing's existence, explain it, and must belong to it [Kung] |
Full Idea: Three essentialist claims are labelled 'Aristotelian': the thing would cease to exist without the property; an essential property is explanatory; and it is such that it must belong to everything to which it belongs. | |
From: Joan Kung (Aristotle on Essence and Explanation [1977], Intro) | |
A reaction: She says the second one is indispensable, and that it rules out the third one. My working assumption, like hers, is that the second one is the key part of the game, because Aristotle wanted to explain things. |
