“Where we have strong emotions, we’re liable to fool ourselves.”

Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.

For small creatures such as we the vastness is bearable only through love.

An atheist is someone who is certain that God does not exist, someone who has compelling evidence against the existence of God.

The only thing we’ve found that makes the emptiness bearable, is each other.

Exploration is in our nature. We began as wanderers, and we are wanderers still. We have lingered long enough on the shores of the cosmic ocean. We are ready at last to set sail for the stars.

If it can be destroyed by the truth, it deserves to be destroyed by the truth.

Your god is too small for my universe.

A galaxy is composed of gas and dust and stars – billions upon billions of stars. Every star may be a sun to someone.

One of the great commandments of science is: Mistrust arguments from authority.

Extinction is the rule. Survival is the exception.

I don’t want to believe. I want to know.

If we ruin the earth, there is no place else to go.

The significance of our lives and our fragile planet is then determined only by our own wisdom and courage.

All civilizations become either spacefaring or extinct.

If we continue to accumulate only power and not wisdom, we will surely destroy ourselves.

Across the sea of space, the stars are other suns.

Atheism is just a way of clearing the space for better conversations.

I don’t say that I’m an atheist. I don’t like that term, because I think it mirrors the certitude of religion. I say I don’t know. And if you don’t know – and you don’t – just man up and say you don’t know. Don’t turn to silly stories and ancient myths.

Idiots must stop claiming that atheism is a religion. Religion is defined as the belief in and worship of a superhuman controlling power. And atheism is… precisely not that. Atheism is a religion like abstinence is a sex position.

The number one cause of atheism is Christians. Those who proclaim Him with their mouths and deny Him with their actions is what an unbelieving world finds unbelievable.

Atheists have just as much civil right to teach atheism as Christians have to teach Christianity; agnostics have just as much right to teach agnosticism as Christians have to teach their religion.

The parents have a right to say that no teacher paid by their money shall rob their children of faith in God and send them back to their homes skeptical, or infidels, or agnostics, or atheists.

The equal toleration of all religions…is the same as atheism.

The person who follows the pursuit of reason unflinchingly toward its end will be atheistic or, at best, agnostic.
