Who ever saw a doctor use the prescription of his colleague without cutting out or adding something?

I admire the assurance and confidence everyone has in himself, whereas there is hardly anything I am sure I know or that I dare give my word I can do.

If I were of the trade, I should naturalize art as much as they "artialize" nature.

Can anything be imagined so ridiculous that this miserable and wretched creature, who is not so much as master of himself, but subject to the injuries of all things, should call himself master and emperor of the world, of which he has not power to know the least part, much less to command the whole?

For all parts of the body that we see fit to expose to the wind and air are found fit to endure it: face, feet, hands, legs, shoulders, head, according as custom invites us. For if there is a part of us that is tender and that seems as though it should fear the cold, it should be the stomach, where digestion takes place; our fathers left it uncovered, and our ladies, soft and delicate as they are, sometimes go half bare down to the navel.

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

No pleasure has any savor for me without communication.
