"It was said by Sir Thomas More that to give up witchcraft was to give up the Bible itself. This idea was entertained by nearly all the eminent theologians of a hundred years ago. In my judgment, they were right. To give up witchcraft is to give up, in a great degree at least, the supernatural. To throw away the little ghosts simply prepares the mind of man to give up the great ones. The founders of nearly all creeds, and of all religions properly so called, have taught the existence of good and evil spirits. They have peopled the dark with devils and the light with angels. They have crowded hell with demons and heaven with seraphs. The moment these good and evil spirits, these angels and fiends, disappear from the imaginations of men, and phenomena are accounted for by natural rather than by supernatural means, a great step has been taken in the direction of what is now known as materialism. While the church believes in witchcraft, it is in a greatly modified form. The evil spirits are not as plenty as in former times, and more phenomena are accounted for by natural means. Just to the extent that belief has been lost in spirits, just to that extent the church has lost its power and authority. When men ceased to account for the happening of any event by ascribing it to the direct action of good or evil spirits, and began to reason from known premises, the chains of superstition began to grow weak."

“After all, of what use is it to search for a creator? The difficulty is not thus solved. You leave your creator as much in need of a creator as anything your creator is supposed to have created. The bottom of your stairs rests on nothing, and the top of your stairs leans upon nothing. You have reached no solution. The word “God” is simply born of our ignorance. We go as far as we can, and we say the rest of the way is “God.” We look as far as we can, and beyond the horizon, where there is nought so far as we know but blindness, we place our Deity. We see an infinitesimal segment of a circle, and we say the rest is “God.”

“I happened to be in the company of six or seven Baptist elders—how I ever got into such bad company, I don’t know,—and one of them asked what I thought about baptism. Well, I never thought much about it; did not know much about it; didn’t want to say anything, but they insisted upon it. I said, “Well, I’ll give you my opinion—with soap, baptism is a good thing.”

“Good-by, gentlemen! I am not asking to be Governor of Illinois … I have in my composition that which I have declared to the world as my views upon religion. My position I would not, under any circumstances, not even for my life, seem to renounce. I would rather refuse to be President of the United States than to do so. My religious belief is my own. It belongs to me, not to the State of Illinois. I would not smother one sentiment of my heart to be the Emperor of the round world.”

“Nothing could tempt me to do this man injustice, though I could hardly add to the injury he has done himself.”

“The hands that help are holier than the lips that pray.”

“Our ancestors in the ages that are gone really believed that by force you could convince a man. You cannot change the conclusion of the brain by force, but I will tell you what you can do by force, and what you have done by force. You can make hypocrites by the million.”
