Aristotle on Atomism

Abstract

Two kinds of atomism emerged in the philosophy off the Presocratics. One kind was devised as a response to Parmenides and involved indivisible physical atoms. The other kind emerged in response to Zeno’s paradoxes and involved indivisible magnitudes that served as a barrier to the infinite division that led to those paradoxes. I argue, contrary to a range of positions to be found in the literature that Aristotle was aware of the distinction between the two kinds of atomism, did not attribute an atomism involving indivisible magnitudes to Democritus, and countered the two kinds of atomism with distinct kinds of arguments.
