Diogenes of Sinope quotes - page 2
On reaching Athens he fell in with Antisthenes. Being repulsed by him, because he never welcomed pupils, by sheer persistence Diogenes wore him out. Once when he stretched out his staff against him, the pupil offered his head with the words, "Strike, for you will find no wood hard enough to keep me away from you, so long as I think you've something to say."
Diogenes of Sinope
Diogenes the cynic, seeing one of the so-called freedmen pluming himself, while many heartily congratulated him, marveled at the absence of reason and discernment. "A man might as well,” he said, "proclaim that one of his servants became a grammarian, a geometrician, or musician, when he has no idea whatever of the art.” For as the proclamation cannot make them men of knowledge, so neither can it make them free.
