The Logical Contingency of Identity

Hanoch Ben-Yami ; Central European University

Sažetak

I show that intuitive and logical considerations do not justify introducing Leibniz’s Law of the Indiscernibility of Identicals in more than a limited form, as applying to atomic formulas. Once this is accepted, it follows that Leibniz’s Law generalises to all formulas of the first-order Predicate Calculus but not to modal formulas. Among other things, identity turns out to be logically contingent.

Ključne riječi

Leibniz’s Law; indiscernibility of identicals; identity; necessity; contingency
