Diogenes (412–323 B.C.) was a Greek Cynic philosopher who rejected conventional society norms.
Diogenes, who made such a parade of his independence with his barrel, was seized with an intestinal attack from eating a raw polypus. So he lost his life through gluttony. Tatian (c. 160, E), 1.65
In the house of a bad man, Diogenes found the inscription, “Hercules, for victory famed, dwells here. Let nothing bad enter.” So Diogenes remarked, “So how will the master of the house go in?” Clement of Alexandria (c. 195, E), 2.529
Long ago, indeed, there was a Greek philosopher who preferred a state of poverty. Yet, he exhibited the pattern of a happy life. He thereby showed that he was not excluded from happiness, even though he possessed nothing. So he termed himself a Cynic. Origen (c. 248, E), 4.586
