Reason is the light, the sun of the brain. It is the compass of the mind, the ever-constant Northern Star, the mountain peak that lifts itself above all clouds.

The most important thing in this world is liberty. More important than food or clothes - more important than gold or houses or lands - more important than art or science - more important than all religions, is the liberty of man.

To hate man and worship God seems to be the sum of all the creeds.

If the reason I give is a good one, you will act upon it. If it is a bad one I cannot make it better by piling epithet upon epithet. There is no logic in abuse; there is no argument in an epithet.

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!"

I am anxious to give away information, for it is only by giving it away that you can keep it. When you have told it, you remember it. It is with information as it is with liberty, the only way to be dead sure of it is to give it to other people.

I read the other day an account of a meeting between John Knox and John Calvin. Imagine a dialogue between a pestilence and a famine!
