The greatest test of courage on earth is to bear defeat without losing heart.

The mechanic, when a wheel refuses to turn, never thinks of dropping on his knees and asking the assistance of some divine power. He knows there is a reason. He knows that something is too large or too small; that there is something wrong with his machine; and he goes to work and he makes it larger or smaller, here or there, until the wheel will turn.

We all know that men in moderate circumstances can have just as comfortable houses as the richest, just as comfortable clothing, just as good food. They can see just as fine paintings, just as marvelous statues, and they can hear just as good music. They can attend the same theaters and the same operas. They can enjoy the same sunshine, and above all, can love and be loved just as well as kings and millionaires.

Every pulpit is a pillory, in which stands a hired culprit, defending the justice of his own imprisonment.

The glory of science is, that it is freeing the soul, breaking the mental manacles, getting the brain out of bondage, giving courage to thought, filling the world with mercy, justice, and joy.

The ministers are in duty bound to denounce all intellectual pride, and show that we are never quite so dear to God as when we admit that we are poor, corrupt and idiotic worms; that we never should have been born; that we ought to be damned without the least delay.... The old creed is still taught. They still insist that God is infinitely wise, powerful and good, and that all men are totally depraved. They insist that the best man god ever made, deserved to be damned the moment he was finished.

Either god should have written a book to fit my brain, or he should have made my brain to fit his book.
