Leibniz on the existence of atoms

ABSTRACT In this paper I present and evaluate Leibniz’s two main arguments against the existence of atoms. In this context atoms are extended particles that are absolutely hard, homogeneous, indivisible, and indestructible by natural means. As we shall see, Leibniz’s arguments are flawed in a very instructive way. The first argument is in tension with the claim that God created the best possible world. The second argument overgeneralizes in an undesirable way. However, as I shall discuss in the last section of the paper, even if the arguments are somehow defective, at least the first one contributes valuable insights to contemporary metaphysics.
