9. Objects / F. Identity among Objects / 1. Concept of Identity
Identity does not exclude possible or imagined difference [Suárez, by Boulter]
     Full Idea: To be really the same excludes being really other, but does not exclude being other modally or mentally.
     From: report of Francisco Suárez (Disputationes metaphysicae [1597], 7.65) by Stephen Boulter - Why Medieval Philosophy Matters 4
     A reaction: So the statue and the clay are identical, but they could become separate, or be imagined as separate.
Real Essential distinction: A and B are of different natural kinds [Suárez, by Boulter]
     Full Idea: The Real Essential distinction says if A and B are not of the same natural kind, then they are essentially distinct. This is the highest degree of distinction.
     From: report of Francisco Suárez (Disputationes metaphysicae [1597], Bk VII) by Stephen Boulter - Why Medieval Philosophy Matters 4
     A reaction: Boulter says Peter is essentially distinct from a cabbage, because neither has the nature of the other.
Minor Real distinction: B needs A, but A doesn't need B [Suárez, by Boulter]
     Full Idea: The Minor Real distinction is if A can exist without B, but B ceases to exist without A.
     From: report of Francisco Suárez (Disputationes metaphysicae [1597], Bk VII) by Stephen Boulter - Why Medieval Philosophy Matters 4
     A reaction: This is one-way independence. Boulter's example is Peter and Peter's actual weight.
Major Real distinction: A and B have independent existences [Suárez, by Boulter]
     Full Idea: The Major Real distinction is if A can exist in the real order without B, and B can exist in the real order without A.
     From: report of Francisco Suárez (Disputationes metaphysicae [1597], Bk VII) by Stephen Boulter - Why Medieval Philosophy Matters 4
     A reaction: Boulter's example is the distinction between Peter and Paul, where their identity of kind is irrelevant. This is two-way independence.
Conceptual/Mental distinction: one thing can be conceived of in two different ways [Suárez, by Boulter]
     Full Idea: The Conceptual or Mental distinction is when A and B are actually identical but we have two different ways of conceiving them.
     From: report of Francisco Suárez (Disputationes metaphysicae [1597], Bk VII) by Stephen Boulter - Why Medieval Philosophy Matters 4
     A reaction: This is the Morning and Evening Star. I bet Frege never read Suarez. This seems to be Spinoza's concept of mind/body.
Modal distinction: A isn't B or its property, but still needs B [Suárez, by Boulter]
     Full Idea: The Modal distinction is when A is not B or a property of B, but still could not possibly exist without B.
     From: report of Francisco Suárez (Disputationes metaphysicae [1597], Bk VII) by Stephen Boulter - Why Medieval Philosophy Matters 4
     A reaction: Duns Scotus proposed in, Ockham rejected it, but Suarez supports it. Suarez proposes that light's dependence on the Sun is distinct from the light itself, in this 'modal' way.
We should talk of the transitivity of 'identity', and of 'definite identity' [Inwagen]
     Full Idea: In some contexts, the principle of 'the transitivity of identity' should be called 'the transitivity of definite identity'.
     From: Peter van Inwagen (Material Beings [1990], 18)
     A reaction: He is making room for a person to retain identity despite having changed. Applause from me.
