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.

For ages, a deadly conflict has been waged between a few brave men and women of thought and genius upon the one side, and the great ignorant religious mass on the other. This is the war between Science and Faith. The few have appealed to reason, to honor, to law, to freedom, to the known, and to happiness here in this world. The many have appealed to prejudice, to fear, to miracle, to slavery, to the unknown, and to misery hereafter. The few have said "Think" The many have said "Believe!"

For the most part we inherit our opinions. We are the heirs of habits and mental customs. Our beliefs, like the fashion of our garments, depend on where we were born. We are molded and fashioned by our surroundings.

A believer is a bird in a cage, a freethinker is an eagle parting the clouds with tireless wing.

There is more real devotional feeling summoned from the temple of the mind by great music than by any sermon ever delivered.

Would God give a bird wings and make it a crime to fly? Would he give me brains and make it a crime to think? Any God that would damn one of his children for the expression of his honest thought wouldn't make a decent thief. When I read a book and don't believe it, I ought to say so. I will do so and take the consequences like a man.

I do not believe in loving enemies; I have pretty hard work to love my friends. Neither do I believe in revenge. No man can afford to keep the viper of revenge in his heart. But I believe in justice, in self-defense.
