„Sweet exists by convention, bitter by convention, colour by convention; atoms and Void [alone] exist in reality. (trans. Freeman 1948), p. 92.“
— Democritus Ancient Greek philosopher, pupil of Leucippus, founder of the atomic theory
By convention sweet is sweet, bitter is bitter, hot is hot, cold is cold, color is color; but in truth there are only atoms and the void. (trans. Durant 1939), Ch. XVI, §II, p. 353; citing C. Bakewell, Sourcebook in Ancient Philosophy, New York, 1909, "Fragment O" (Diels), p. 60
