Question

Counterexamples to this statement can be resolved by finding an irreflexive symmetric relation, which is Quine's “weak” form of a related property. This statement is invoked in a passage that argues the universe would be no different if God moved it “forward in a right line,” contra substantivalism. Interlocutor B rejects this statement by imagining a perfectly symmetrical universe consisting of two iron, mile-wide spheres in a paper by Max Black. The application of this (15[1])statement to intensional contexts is called the (*) “masked man” fallacy. This statement can be expressed in symbolic logic as (read slowly:) if for all properties F, Fx if and only if Fy, then x equals y. In letters to Samuel Clarke, this statement was derived from its formulator's Principle of Sufficient Reason. (10[1])For 10 points, name this principle that states that any two objects with all the same properties are the same. ■END■ (0[2])
