9. Objects / F. Identity among Objects / 1. Concept of Identity
Real identity admits of no degrees [Reid]
     Full Idea: Wherever identity is real, it admits of no degrees.
     From: Thomas Reid (Essays on Intellectual Powers 5: Abstraction [1785]), quoted by David Wiggins - Sameness and Substance Renewed 6 epig
     A reaction: Wiggins quotes this with strong approval. Personally I am inclined to think that identity may admit of no degrees in human thought, because that is the only way we can do it, but the world is full of uncertain identities, at every level.
Identity is familiar to common sense, but very hard to define [Reid]
     Full Idea: Every man of common sense has a clear and distinct notion of identity. If you ask for a definition of identity, I confess I can give none. It is too simple a notion.
     From: Thomas Reid (Essays on Intellectual Powers 3: Memory [1785], III.Ch 4)
     A reaction: 'Identical' seems to be a two-place predicate, but the only strict way two things can be identical is if there is actually just one thing. In which case just drop the word 'identity' (instead of defining it), and say there is just one thing here.
Identity can only be affirmed of things which have a continued existence [Reid]
     Full Idea: Identity can only be affirmed of things which have a continued existence.
     From: Thomas Reid (Essays on Intellectual Powers 3: Memory [1785], III.Ch 6)
     A reaction: This doesn't mean that Reid thinks there is nothing more to the identity than their similitude. But he, like Hume, denies that there is personal identity at any given instant. Reid is better at criticism than at formulating his own theory.
