Detail: He combined ideas of Parmenides and Empedocles. Infinite numbers of very small particles {atom, Leucippus}, differing in size, form, and other quantitative features, move in empty space. Atom types are eternal, indestructible, unchangeable, indivisible, homogeneous, and finite. Atom motion is eternal, deterministic, and without cause or purpose. Atom motions are change or becoming. Space exists but is not material. Objects are atom combinations. Quantitative atom differences cause qualitative differences.
