We can be knowledgeable with other men's knowledge, but we cannot be wise with other men's wisdom.

Off I go, rummaging about in books for sayings which please me.

Anyone who does not feel sufficiently strong in memory should not meddle with lying.

Amongst so many borrowed things, am glad if I can steal one, disguising and altering it for some new service.

The worst of my actions or conditions seem not so ugly unto me as I find it both ugly and base not to dare to avouch for them.

I care not so much what I am to others as what I am to myself. I will be rich by myself, and not by borrowing.

Though we may be learned by another's knowledge, we can never be wise but by our own experience.
