11380 | Two things with the same primary being and essence are one thing [Aristotle] |
Full Idea: If any two items have a single substance [ousia, primary being] and a single what-it-is-to-be-that-thing [to ti en einai, essence], then they are themselves a single thing. | |
From: Aristotle (Metaphysics [c.324 BCE], 1038b14) | |
A reaction: [alternative translations by Vasilis Politis] This isn't quite the identity of indiscernibles, because it allows superficial identity along with deep difference (H2O and XYZ, for example, or jadeite and nephrite). |
17848 | Things such as two different quadrangles are alike but not wholly the same [Aristotle] |
Full Idea: Things are alike if they are not just the same simpliciter, exhibiting differences in their substrate substance but being formally the same. Examples are larger and smaller quadrangles and unequal straight lines, which are alike but not the same. | |
From: Aristotle (Metaphysics [c.324 BCE], 1054b06) |
10024 | The type-token distinction is the universal-particular distinction [Armstrong, by Hodes] |
Full Idea: Armstrong conflates the type-token distinction with that between universals and particulars. | |
From: report of David M. Armstrong (A Theory of Universals [1978], xiii,16/17) by Harold Hodes - Logicism and Ontological Commits. of Arithmetic 147 n23 | |
A reaction: This seems quite reasonable, even if you don’t believe in the reality of universals. I'm beginning to think we should just use the term 'general' instead of 'universal'. 'Type' also seems to correspond to 'set', with the 'token' as the 'member'. |
10728 | A thing's self-identity can't be a universal, since we can know it a priori [Armstrong, by Oliver] |
Full Idea: Armstrong says that if it can be proved a priori that a thing falls under a certain universal, then there is no such universal - and hence there is no universal of a thing being identical with itself. | |
From: report of David M. Armstrong (A Theory of Universals [1978], II p.11) by Alex Oliver - The Metaphysics of Properties 11 | |
A reaction: This is a distinctively Armstrongian view, based on his belief that universals must be instantiated, and must be discoverable a posteriori, as part of science. I'm baffled by self-identity, but I don't think this argument does the job. |
16134 | We can't understand self-identity without a prior grasp of the object [Aristotle] |
Full Idea: To ask why a thing is identical with itself is not to ask a real question in the absence of a clear grasp of the fact ….or of the object. | |
From: Aristotle (Metaphysics [c.324 BCE], 1041a12) | |
A reaction: This seems a very nice response to Lewis's attempt to sweep difficulties of identity aside, when he rests identity on primitive self-identity. |
17847 | You are one with yourself in form and matter [Aristotle] |
Full Idea: You are one with yourself both in form and in matter. | |
From: Aristotle (Metaphysics [c.324 BCE], 1054a35) |
