" "Man should know from this rule that he is cut off from truth.
Democritus (c. 460 BC – c. 370 BC) was a pre-Socratic Greek philosopher. He is popularly known as "the laughing philosopher" for advocating a cheerful outlook, and for his rhetorical use of irony and ridicule. A pupil of Leucippus, he was an influential pre-Socratic philosopher who formulated an atomic theory of the universe. Of his voluminous writings, only a few fragments of his ethical theory remain, with descriptions by other writers of his atomic theory.
