A classic is something that everybody wants to have read and nobody wants to read.
Whatever you do, do it to the purpose; do it thoroughly, not superficially. Go to the bottom of things. Any thing half done, or half known, is in my mind, neither done nor known at all. Nay, worse, for it often misleads.
Misquotations are the only quotations that are never misquoted.
A hypocrite is a person who--but who isn't?
He who will not reason is a bigot; he who cannot is a fool; and he who dares not is a slave.
It is wonderful how quickly you get used to things, even the most astonishing.
Speak properly, and in as few words as you can, but always plainly; for the end of speech is not ostentation, but to be understood.
