Anger is a wind which blows out the lamp of the mind.

Do right, not to deny yourself but because you love yourself and because you love others.

I want it so that every minister will be not a parrot, not an owl sitting upon a dead limb of the tree of knowledge and hooting the hoots that have been hooted for eighteen hundred years. But I want it so that each one can be an investigator, a thinker; and I want to make his congregation grand enough so that they will not only allow him to think, but will demand that he shall think, and give to them the honest truth of his thought.

I do not believe in loving enemies; I have pretty hard work to love my friends.

The greatest superstition now entertained by public men is that hypocrisy is the royal road to success.
