Religion is a temper, not a pursuit. It is the moral atmosphere in which human beings are to live and move. Men do not live to breathe: they breathe to live.

I wrote because I could not help it. There was something that I wanted to say, and I said it: that was all. The fame and the money and the usefulness might or might not follow. It was not by my endeavor if they did.

I would not exchange my freedom from old superstition, if I were to be burned at the stake next month, for all the peace and quiet of orthodoxy, if I must take the orthodoxy with peace and quiet.

Any one must see at a glance that if men and women marry those whom they do not love, they must love those whom they do not marry.

Of tobacco and its consequences, I will say nothing but that the practice is at too bad a pass to leave hope that anything that could be said in books would work a cure. If the floors of boarding-houses, and the decks of steam-boats, and the carpets of the Capitol, do not sicken the Americans into a reform; if the warnings of physicians are of no avail, what remains to be said? I dismiss the nauseous subject.

I certainly never believed, more or less, in the "essential doctrines" of Christianity, which represent God as the predestinator of men to sin and perdition, and Christ as their rescuer from that doom. I never was more or less behuiled by the trickery of language by which the perdition of man is made out to be justice, and his redemption to be mercy.
