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

I love to think of the whole universe together as one eternal fact. I love to think that everything is alive; that crystallization is itself a step toward joy. I love to think that when a bud bursts into blossom: it feels a thrill. I love to have the universe full of feeling and full of joy, and not full of simple dead, inert matter, managed by an old bachelor for all eternity.

I would rather live with the woman I love in a world full of trouble, than to live in heaven with nobody but men.

Let us account for all we see by the facts we know. If there are things for which we cannot account, let us wait for light. To account for anything by supernatural agencies is, in fact to say that we do not know. Theology is not what we know about God, but what we do not know about Nature.

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

All laws for the purpose of making man worship God, are born of the same spirit that kindled the fires of the auto da fe, and lovingly built the dungeons of the Inquisition. All laws defining and punishing blasphemy - making it a crime to give your honest ideas about the Bible, or to laugh at the ignorance of the ancient Jews, or to enjoy yourself on the Sabbath, or to give your opinion of Jehovah, were passed by impudent bigots, and should be at once repealed by honest men. An infinite God ought to be able to protect himself, without going in partnership with State Legislatures.

I would have all the professors in colleges, all the teachers in schools of every kind, including those in Sunday schools, agree that they would teach only what they know, that they would not palm off guesses as demonstrated truths.
