7. Existence / C. Structure of Existence / 5. Supervenience / c. Significance of supervenience
Two things being joined together doesn't prove they are the same [Descartes]
     Full Idea: The fact that we often see two things joined together does not license the inference that they are one and the same.
     From: René Descartes (Reply to Sixth Objections [1641], 444)
     A reaction: Correct. The problem comes when they are never ever apart, and you begin to suspect that they are conjoined in all possible worlds. Why might this be so? It can only be identity or a causal link.
7. Existence / C. Structure of Existence / 8. Stuff / b. Mixtures
If a mixture does not contain measure and proportion, it is corrupted and destroyed [Plato]
     Full Idea: Any kind of mixture that does not ...possess measure or the nature of proportion will necessarily corrupt its ingredients and most of all itself. For there would be no blending in such cases but really an unconnected medley, and ruin what contains it.
     From: Plato (Philebus [c.353 BCE], 64d)
     A reaction: My guess is that Plato is thinking of the decay of living things when they die, losing the proportions of psuché, and then applying this to the unity of inanimate objects as well. One might compare Leibniz's monads.
Any mixture which lacks measure and proportion doesn't even count as a mixture at all [Plato]
     Full Idea: Any blend [mixture] which does not have measure or the nature of proportion in any way whatsoever, of necessity destroys both its ingredients and, primarily, itself. It is truly no blend at all, but a kind of unblended disaster.
     From: Plato (Philebus [c.353 BCE], 64e)
     A reaction: Obviously there can be chaotic mixtures, but I guess Plato is picking out mixtures about which we can say something
