Note 195 — Chapter V · FREETHOUGHT IN GREECE

While Athens was gaining power and glory and beauty without popular wisdom, the colonial city of Abdera, in Thrace, founded by Ionians, had like others carried on the great impulse of Ionian philosophy, and had produced in the fifth century some of the great thinkers of the race. Concerning the greatest of these, Demokritos, and the next in importance, Protagoras, we have no sure dates;195 but it is probable that the second, whether older or younger, was influenced by the first, who indeed has influenced all scientific philosophy down to our own day. How much he learned from his master Leukippos cannot now be ascertained.196 The writings which went under his name appear to have been the productions of the whole Abderite school;197 and Epicurus declared that Leukippos was an imaginary person.198 What passes for his teaching was constructive science of cardinal importance; for it is the first clear statement of the atomic theory; the substitution of a real for an abstract foundation of things. Whoever were the originator of the theory, there is no doubt as to the assimilation of the principle by Demokritos, who thus logically continued the non-theistic line of thought, and developed one of the most fruitful of all scientific principles. That this idea again is a direct development from Babylonian science is not impossible; at least there seems to be no doubt that Demokritos had travelled far and wide,199 whether or not he had been brought up, as the tradition goes, by Persian magi;200 and that he told how the cosmic views of Anaxagoras, which scandalized the Athenians, were current in the East.201 But he stands out as one of the most original minds in the whole history of thought. No Greek thinker, not Aristotle himself, has struck so deep as he into fundamental problems; though the absurd label of “the laughing philosopher,” bestowed on him by some peculiarly unphilosophic mind, has delayed the later recognition of his greatness, clear as it was to Bacon.202 The vital maxim, “Nothing from nothing: nothing into nothing,” derives substantially from him.203
