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

We are like butterflies who flutter for a day and think it is forever.

Science is a way of thinking much more than it is a body of knowledge.

There are no forbidden questions in science, no matters too sensitive or delicate to be probed, no sacred truths.

Those at too great a distance may, I am well are, mistake ignorance for perspective.

Arguments from authority carry little weight, authorities have made mistakes in the past. They will do so again in the future. Perhaps a better way to say it is that in science there are no authorities; at most, there are experts.

Other things being equal, it is better to be smart than to be stupid.

I think the health of our civilization, the depth of our awareness about the underpinnings of our culture and our concern for the future can all be tested by how well we support our libraries.

Don’t judge everyone else by your own limited experience.

The total number of stars in the Universe is larger than all the grains of sand on all the beaches of the planet Earth.

People are not stupid. They believe things for reasons.

There are as many atoms in one molecule of DNA as there are stars in a typical galaxy.

Stars are phoenixes, rising from their own ashes.

The cure for a fallacious argument is a better argument, not the suppression of ideas.

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

Creationists eagerly seek a gap in present-day knowledge or understanding. If an apparent gap is found, it is assumed that God, by default, must fill it.

Sometimes when I’m faced with an atheist, I am tempted to invite him to the greatest gourmet dinner that one could ever serve, and when we have finished eating that magnificent dinner, to ask him if he believes there’s a cook.

Atheism is so senseless. When I look at the solar system, I see the earth at the right distance from the sun to receive the proper amounts of heat and light. This did not happen by chance.

If there is a God, it’s going to be a whole lot bigger and a whole lot more incomprehensible than anything that any theologian of any religion has ever proposed.

The time has come for people of reason to say: Enough is Enough! Religious faith discourages independent thought, it’s divisive and it’s dangerous.

If the gods do evil then they are not gods.

I do not feel obliged to believe that the same God who has endowed us with senses, reason, and intellect has intended us to forego their use.
