Democritus
Democritus (born c. 460 bce — died c. 370), ancient Greek philosopher, a central figure in the development of philosophical atomism and of the atomic theory of the universe.
  Knowledge of Democritus’s life is largely limited to untrustworthy tradition: it seems that he was a wealthy citizen of Abdera, in Thrace; that he traveled widely in the East; and that he lived to an advanced age. According to Diogenes Laërtius (fl. 3rd century ce), his works numbered 73; only a few hundred fragments have survived, mostly from his treatises on ethics.
  Democritus’s physical and cosmological doctrines were an elaborated and systematized version of those of his teacher, Leucippus. To account for the world’s changing physical phenomena, Democritus asserted that space, or the Void, had an equal right with reality, or Being, to be considered existent. He conceived of the Void as a vacuum, an infinite space in which moved an infinite number of atoms that made up Being (i.e., the physical world). These atoms are eternal and invisible; absolutely small, so small that their size cannot be diminished (hence the name atomon, or “indivisible”); absolutely full and incompressible, as they are without pores and entirely fill the space they occupy; and homogeneous, differing only in shape, arrangement, position, and magnitude. But, while atoms thus differ in quantity, differences of quality are only apparent, owing to the impressions caused on the senses by different configurations and combinations of atoms. A thing is hot or cold, sweet or bitter, or hard or soft only by convention; the only things that exist in reality are atoms and the Void. Thus, the atoms of water and iron are the same, but those of water, being smooth and round and therefore unable to hook onto one another, roll over and over like small globes, whereas those of iron, being rough, jagged, and uneven, cling together and form a solid body. Because all phenomena are composed of the same eternal atoms, it may be said that nothing comes into being or perishes in the absolute sense of the words, although the compounds made out of the atoms are liable to increase and decrease, explaining a thing’s appearance and disappearance, or “birth” and “death.”
  Just as the atoms are uncaused and eternal, so too, according to Democritus, is motion. Democritus posited the fixed and “necessary” laws of a purely mechanical system, in which there was no room for an intelligent cause working toward an end. He explained the origin of the universe as follows. The original motion of the atoms was in all directions — it was a sort of “vibration”; hence there resulted collisions and, in particular, a whirling movement, whereby similar atoms were brought together and united to form larger bodies and worlds. This happened not as the result of any purpose or design but rather merely as the result of “necessity”; i.e., it is the normal manifestation of the nature of the atoms themselves. Atoms and void being infinite in number and extent, and motion having always existed, there must always have been an infinite number of worlds, all consisting of similar atoms in various stages of growth and decay.
  Democritus devoted considerable attention to perception and knowledge. He asserted, for example, that sensations are changes produced in the soul by atoms emitted from other objects that impinge on it; the atoms of the soul can be affected only by the contact of other atoms. But sensations such as sweet and bitter are not as such inherent in the emitted atoms, for they result from effects caused merely by the size and shape of the atoms; e.g., sweet taste is due to round and not excessively small atoms. Democritus also was the first to attempt to explain colour, which he thought was due to the “position” (which he differentiated from shape) of the constituent atoms of compounds. The sensation of white, for instance, is caused by atoms that are smooth and flat so as to cast no shadow; the sensation of black is caused by rough, uneven atoms.
  Democritus attributed popular belief in the gods to a desire to explain extraordinary phenomena (thunder, lightning, earthquakes) by reference to superhuman agency. His ethical system, founded on a practical basis, posited an ultimate good (“cheerfulness”) that was “a state in which the soul lives peacefully and tranquilly, undisturbed by fear or superstition or any other feeling.”
