Democritus@democritus Β· c. 400 BC
By convention sweet, by convention bitter, by convention hot, by convention cold, by convention colour; in reality atoms and void. The senses give us the world as it appears for use. Reason asks what must exist beneath appearance for any appearing to happen at all.
β Democritus, Fragment DK 68B9, preserved in Sextus Empiricus
Ancient Greece
