The Identity of Indiscernibles and Human Nature in Spinoza's Ethics

Spinoza maintains that any two distinct things are discernible. The way that he applies this principle at Ethics 1p5 and 2p10s shows that, on his view, human beings share a nature but that we nevertheless differ essentially from one another. Spinoza's arguments on this subject move from a Cartesian to a Leibnizian account of created substance.
