Leucippus thereby reinstated both plurality and change; the void is that which separates the atoms and that through which they move. It seems likely that Democritus as a pupil of Leucippus, developed the ideas of his teacher but it is quite beyond us to disentangle the contributions of each to this important doctrine. Democritus's theories were generally less crude, and he attempted rational explanations of a wide variety of obscure phenomena. "Pleasure as the 'Criterion' in Democritus."

The first proponents of an atomic theory were the Greek philosophers Leucippus and Democritus who proposed the following model in the fifth century B.C. (We do not feel bombarded by individual particles in the air.) Atoms are solid, homogeneous, indivisible, and unchangeable. Moreover, what is the contribution of leucippus in atomic theory?
