Epicurus — "The noble soul occupies itself with wisdom and friendship."

"No pleasure is a bad thing in itself; but the means by which certain pleasures are gained bring troubles many times greater than the pleasures."

"The magnitude of pleasure reaches its limit in the removal of all pain. When that point is attained, pleasure does not further increase, but only varies in kind."

"A free life cannot acquire many possessions, because this is no easy thing to do without servility to mobs or monarchs."

"It is impossible for someone to dispel his fears about the most important matters if he does not understand the nature of the universe but still gives some credence to myths. So that without the study…"

"The beginning and the root of all good is the pleasure of the stomach; even wisdom and culture must be referred to this."
