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

I have no confidence in any religion that can be demonstrated only to children.

The church in all ages and among all peoples has been the consistent enemy of the human race. Everywhere and at all times, it has opposed the liberty of thought and expression. It has been the sworn enemy of investigation and intellectual development. It has denied the existence of facts, the tendency of which was to undermine its power. It has always been carrying fagots to the feet of Philosophy. It has erected the gallows for Genius. It has built the dungeon for Thinkers.

To the wise man, to the wise nation, the mistakes of the past are the torches of the present.

It is better to deserve without receiving than to receive without deserving

Not one of the orthodox ministers dare preach what he thinks if he knows a majority of his congregation think otherwise. He knows that every member of his church stands guard over his brain with a creed, like a club, in his hand. He knows that he is not expected to search after the truth, but that he is employed to defend the creed. Every pulpit is a pillory, in which stands a hired culprit, defending the justice of his own imprisonment.

It is a blessed thing that in every age some one has had individuality enough and courage enough to stand by his own convictions, -- some one who had the grandeur to say his say. I believe it was Magellan who said, The church says the earth is flat; but I have seen its shadow on the moon, and I have more confidence even in a shadow than in the church. On the prow of his ship were disobedience, defiance, scorn, and success.
