Leucippus Quotes

Leucippus was an ancient Greek pre-Socratic philosopher and the founder, with his pupil Democritus, of the atomist tradition. Almost nothing survives of his biography or writings, and his very existence was doubted by Epicurus, but Aristotle and Theophrastus credit him with first formulating the view that the world consists of indivisible particles, atoms, moving in an empty void.
