 Aristotle frequently pairs Leucippus and Democritus in his reports, including his account of the motivation for positing atoms and void. In particular, Aristotle associates Leucippus as well as Democritus with the deliberately paradoxical assertion that ‘being is no more than not-being,’ i.e., that void exists as much as the full or solid (DK 67A6). Schofield (2002) has argued that the more careful account in Simplicius shows that the ou mallon or ‘no more’ doctrine is due to Democritus. Following this lead, Graham (2008) suggests a new reading of Leucippus, wherein the distinction between atom and void is actually based on a reading of Parmenides' Doxa, his cosmological account. Rather than logical abstractions, Being and Not-being, Leucippus' atoms would in essence be based on Parmenides' cosomological contraries, night and light. If this line of interpretation is followed, Leucippus' notion of atom and void might have been rather different from Democritus', and Aristotle's tendency to refer to the two in conjunction somewhat misleading.
