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

"Every other knowledge is harmful to him who does not have knowledge of goodness."

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

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

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

"Why do people respect the package rather than the man?"
