Our civil rights have no dependence upon our religious opinions more than our opinions in physics or geometry.

The clergy, by getting themselves established by law and in-grafted into the machine of government, have been a very formidable engine against the civil and religious rights of man.

The legitimate powers of government extend to such acts only as are injurious to others. But it does me no injury for my neighbor to say there are twenty gods, or no god. It neither picks my pocket nor breaks my leg.

It is between fifty and sixty years since I read it (i.e. the Book of Revelations), and I then considered it merely the ravings of a maniac, no more worthy nor capable of explanation than the incoherence of our own nightly dreams.

If we did a good act merely from love of God and a belief that it is pleasing to Him, whence arises the morality of the Atheist? ...Their virtue, then, must have had some other foundation than the love of God.

From the dissensions among Sects themselves arise necessarily a right of choosing and necessity of deliberating to which we will conform. But if we choose for ourselves, we must allow others to choose also, and so reciprocally, this establishes religious liberty.

The day will come when the mystical generation of Jesus, by the Supreme Being as his father, in the womb of a virgin, will be classed with the fable of the generation of Minerva in the brain of Jupiter.

I am opposed to any form of tyranny over the mind of man.

The law for religious freedom... [has]put down the aristocracy of the clergy and restored to the citizen the freedom of the mind.
