The Identity of Indiscernibles is a principle of analytic ontology first
explicitly formulated by Wilhelm Gottfried Leibniz in his Discourse on
Metaphysics, Section 9 (Loemker 1969: 308). It states that no two distinct
substances exactly resemble each other. This is often referred to as
'Leibniz's Law' and is typically understood to mean that no two objects have
exactly the same properties. The Identity of Indiscernibles is of interest
because it raises questions about the factors which individuate
qualitatively identical objects. Recent work on the interpretation of
quantum mechanics suggests that the principle fails in the quantum domain.
