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.

All religions are inconsistent with mental freedom. Shakespeare is my bible, Burns my hymn-book.

Only a few years ago there was no person too ignorant to successfully answer Charles Darwin; and the more ignorant he was the more cheerfully he undertook the task.

When your little child tells a lie, do not rush at him as though the world were about to go into bankruptcy. Be honest with him. A tyrant father will have liars for his children; do you know that? A lie is born of tyranny upon the one hand and weakness upon the other, and when you rush at a poor little boy with a club in your hand, of course he lies.

Certainly the Old Testament does not teach us that there is another life, and upon that question even the New is obscure and vague. The hunger of the heart finds only a few small and scattered crumbs. There is nothing definite, solid, and satisfying. United with the idea of immortality we find the absurdity of the resurrection. A prophecy that depends for its fulfillment upon an impossibility, cannot satisfy the brain or heart.

All of the Ten Commandments that are good were old; all that were new art foolish. If Jehovah had been civilized he would have left out the commandment about keeping the Sabbath, and in its place would have said: "Thou shalt not enslave thy fellow-men." He would have omitted the one about swearing, and said: "The man shall have but one wife, and the woman but one husband." He would have left out the one about graven images, and in its stead would have said: "Thou shalt not wage wars of extermination, and thou shalt not unsheathe the sword except in self-defence.

Crimes were committed to punish crimes, and crimes were committed to prevent crimes. The world has been filled with prisons and dungeons, with chains and whips, with crosses and gibbets, with thumbscrews and racks, with hangmen and heads-men — and yet these frightful means and instrumentalities have committed far more crimes than they have prevented.... Ignorance, filth, and poverty are the missionaries of crime. As long as dishonorable success outranks honest effort — as long as society bows and cringes before the great thieves, there will be little ones enough to fill the jails.
