Diogenes

"The foundation of every state is the education of its youth."

"Dogs and philosophers do the greatest good and get the fewest rewards."

"Man is the most intelligent of the animals - and the most silly."

"It is the privilege of the gods to want nothing, and of godlike men to want little."

"When I look upon seamen, men of science and philosophers, man is the wisest of all beings when I look upon priests and prophets nothing is as contemptible as man."

"Those who have virtue always in their mouths, and neglect it in practice, are like a harp, which emits a sound pleasing to others, while itself is insensible of the music."
