If the money is raised by taxation, then the burden will fall where it ought to fall, . . . and the rich and stingy will no longer be able to evade the duties of citizenship and of humanity.

I believe in the religion of reason -- the gospel of this world; in the development of the mind, in the accumulation of intellectual wealth, to the end that man may free himself from superstitious fear, to the end that he may take advantage of the forces of nature to feed and clothe the world.

Not only are we here to protect the public from vicious criminals in the street but also to protect the public from harmful ideas.

There is the same difference between talent and genius that there is between a stone mason and a sculptor

Our ignorance is God; what we know is science. When we abandon the doctrine that some infinite being created matter and force, and enacted a code of laws for their government ... the real priest will then be, not the mouth-piece of some pretended deity, but the interpreter of nature.

Environment is a sculptor - a painter. If we had been born in Constantinople, then most of us would have said: 'There is no God but Allah, and Mohammed is his prophet.' If our parents had lived on the banks of the Ganges, we would have been worshipers of Siva, longing for the heaven of Nirvana. As a rule, children love their parents, believe what they teach, and take great pride in saying that the religion of mother is good enough for them.

All laws for the purpose of making man worship God, are born of the same spirit that kindled the fires of the auto da fe, and lovingly built the dungeons of the Inquisition. All laws defining and punishing blasphemy - making it a crime to give your honest ideas about the Bible, or to laugh at the ignorance of the ancient Jews, or to enjoy yourself on the Sabbath, or to give your opinion of Jehovah, were passed by impudent bigots, and should be at once repealed by honest men. An infinite God ought to be able to protect himself, without going in partnership with State Legislatures.
