I quote others only in order the better to express myself. - Michel de Montaigne, The Complete Essays

"There is nothing more notable in Socrates than that he found time, when he was an old man, to learn music and dancing, and thought it time well spent."

"Learned we may be with another man's learning: we can only be wise with wisdom of our own."

"We must not attach knowledge to the mind, we have to incorporate it there."

"The greatest thing in the world is to know how to belong to oneself."

"Nothing is so firmly believed as that which we least know."
