There are some truths, however, that we should never forget: Superstition has always been the relentless enemy of science; faith has been a hater of demonstration; hypocrisy has been sincere only in its dread of truth, and all religions are inconsistent with mental freedom.

We are not accountable for the sins of "Adam".

The intelligent and good man holds in his affections the good and true of every land -- the boundaries of countries are not the limitations of his sympathies. Caring nothing for race, or color, he loves those who speak other languages and worship other gods. Between him and those who suffer, there is no impassable gulf. He salutes the world, and extends the hand of friendship to the human race. He does not bow before a provincial and patriotic god -- one who protects his tribe or nation, and abhors the rest of mankind.

Intellect, without heart, is infinitely cruel. . . . So that, after all, the real aristocracy must be that of goodness where the intellect is directed by the heart.

Suppose, however, that God did give this law to the Jews, and did tell them that whenever a man preached a heresy, or proposed to worship any other God that they should kill him; and suppose that afterward this same God took upon himself flesh, and came to this very chosen people and taught a different religion, and that thereupon the Jews crucified him; I ask you, did he not reap exactly what he had sown? What right would this god have to complain of a crucifixion suffered in accordance with his own command?

If a man wishes to have God recognized in the constitution of our country, let him read the history of the Inquisition, and let him remember that hundreds of millions of men, women, and children have been sacrificed to placate the wrath, or win the approbation of this god.
