"In a theological seminary, if a professor finds a fact inconsistent with the creed, he must keep it secret or deny it, or lose his place. Mental veracity is a crime, cowardice and hypocrisy are virtues."

“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.

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.”
