Nothing is so firmly believed as that which we least know. - Michel de Montaigne, The Complete Essays

"I quote others only in order the better to express myself."

"Judgement can do without knowledge: but not knowledge without judgement."

"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."

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