Democritus

Note that the atomism alluded to here is different from what is referred to as atomic theory. The atom within the thinking of Leucippus and Democritus refers to atomos as meaning “uncuttable” or “that which cannot be divided.” The plurality we experience is the result of atoms in motion. These indivisible atoms have qualities such as shape, size, and motion that cause them to join and separate in configurations, which give rise to the objects we experience with our senses. In other words, the invisible world of atoms supports and causes the visible world of everyday objects, consisting of taste, color, odor, and sound. Atoms are the true being, and the visible objects are not!
