“A library is not to be read completely, but to be consulted. Here there are books which are around just in case. I have read all my life, but there are many things about which I know nothing. What's important is not to have everything in one's head but to know where to find it. The difference between someone who's vain and someone who's wise is that the vain man only appreciates what he already knows, and the wise man searches for what he doesn't yet know.”
