I belong to the Great Church which holds the world within its starlit aisles; that claims the great and good of every race and clime; that finds with joy the grain of gold in every creed, and floods with light and love the germs of good in every soul.

Superstition is, always has been, and forever will be, the foe of progress, the enemy of education and the assassin of freedom.

Don't you know that if people could bottle the air they would? Don't you know that there would be an American Air-bottling Association? And don't you know that they would allow thousands and millions to die for want of breath, if they could not pay for air? I am not blaming anybody. I am just telling how it is.

While I am opposed to all orthodox creeds, I have a creed myself; and my creed is this. Happiness is the only good. The time to be happy is now. The place to be happy is here. The way to be happy is to make others so. This creed is somewhat short, but it is long enough for this life, strong enough for this world. If there is another world, when we get there we can make another creed.

I would rather that we all should go to eternal chaos, to black and starless night, than that just one soul should suffer eternal agony.

Creationists use facts the same way a drunk uses a lightpost: for support instead of illumination

In all ages the people have honored those who dishonored them. They have worshiped their destroyers; they have canonized the most gigantic liars, and buried the great thieves in marble and gold. Under the loftiest monuments sleeps the dust of murder.
