There are some truths, however, that we should never forget: Superstition has always been the relentless enemy of science; faith has been a hater of demonstration; hypocrisy has been sincere only in its dread of truth, and all religions are inconsistent with mental freedom.

It seems to me impossible for a civilized man to love or worship, or respect the God of the Old Testament. A really civilized man, a really civilized woman, must hold such a God in abhorrence and contempt.

Mental slavery is mental death, and every man who has given up his intellectual freedom is the living coffin of his dead soul.

It is a splendid thing to think that the woman you really love will never grow old to you. Through the wrinkles of time, through the mask of years, if you really love her, you will always see the face you love and won. And a woman who really loves a man does not see that he grows old; he is not decrepit to her; she always sees the same gallant gentleman who won her hand and heart.

Years should not be devoted to the acquisition of dead languages or to the study of history which, for the most part, is a detailed account of things that never occurred. It is useless to fill the individual with dates of great battles, with the births and deaths of kings. They should be taught the philosophy of history, the growth of nations, of philosophies, theories, and, above all, of the sciences.

I hate above all things a cross man. What right has he to murder the sunshine of a day? What right has he to assassinate the Joy of life? When you go home, you ought to go like a ray of light-so that it will, even in the night, burst out of the doors and windows and illuminate the darkness.

I do not believe in loving enemies; I have pretty hard work to love my friends. Neither do I believe in revenge. No man can afford to keep the viper of revenge in his heart. But I believe in justice, in self-defense.
