The greatest thing in the world is to know how to belong to... - Michel de Montaigne, The Complete Essays

"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."

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

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

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