Abraham Lincoln: “If the end brings me out wrong, ten angels swearing I was right would make no difference.”

I do the very best I know how--the very best I can; and I mean to keep doing so until the end.

If I were to try to read, much less answer, all the attacks made on me, this shop might as well be closed for any other business.

As a general rule I abstain from reading the reports of attacks upon myself, wishing not to be provoked by that to which I cannot properly offer an answer.

Important principles may and must be inflexible.
