I have never seen the slightest scientific proof of the religious ideas of heaven and hell, of future life for individuals, or of a personal God.

You do well to wish to learn our arts and ways of life, and above all, the religion of Jesus Christ. These will make you a greater and happier people than you are. Congress will do every thing they can to assist you in this wise intention.

To devote your life to the good of all and to the happiness of all is religion. Whatever you do for your own sake is not religion.

But to show you my heart fully, my friends: if there were gods, how could I bear to be not a god! Therefore, there are no gods.

Religion is the opiate of the masses.

The religious world is but a reflex of the real world.
