“The biggest advantage to believing in God is you don’t have to understand anything, no physics, no biology. I wanted to understand.”

People say it would be terrible if we made all girls pretty. I think it would be great.

Racists have often used pseudoscience to justify their socially damaging views; watch these films to see how science, by replacing ignorance with knowledge, can undo that damage.

It’s necessary to be slightly underemployed if you are to do something significant.

The brain is the last and grandest biological frontier, the most complex thing we have yet discovered in our universe. It contains hundreds of billions of cells interlinked through trillions of connections. The brain boggles the mind.

A clone of Einstein wouldn’t be stupid, but he wouldn’t necessarily be any genius, either.

Science seldom proceeds in the straightforward logical manner imagined by outsiders. Instead, its steps forward (and sometimes backward) are often very human events in which personalities and cultural traditions play major roles.

I turned against the left wing because they don’t like genetics, because genetics implies that sometimes in life we fail because we have bad genes. They want all failure in life to be due to the evil system.

If scientists don’t play God, who will?

I have been much blessed.

Knowing “why” (an idea) is more important than learning “what” (the fact).

We’re not all equal, it’s simply not true. That isn’t science.

Biology has at least 50 more interesting years.

One of the greatest gifts science has brought to the world is continuing elimination of the supernatural.

I don’t think we are here for anything. We’re just products of evolution. You can say, “Gee, your life must be pretty bleak if you don’t think there’s a purpose.” But I’m anticipating a good lunch.

The brain, is the most complex thing we have yet discovered in our universe.

There are many people of color who are very talented.

I believe that when I am dead, I am dead. I believe that with my death I am just as much obliterated as the last mosquito you and I squashed.

If you believe in it, and you believe in it hard, it is impossible to fail.

Visions of McDonald’s restaurants dotting crossroads all over the country paraded through my brain. I don’t believe in saturation. We’re thinking and talking worldwide.

People often ask me whether I believe in God. I haven’t seen God. But I think that one’s beliefs are one’s God – and, in those terms, yes, God is there.

I believe that when you really want to do something, you should go ahead and do it. I mean, I feel fear, but I never let that stop me.

But in that backroom or whatever it is when God confronts me with my sins, I do not believe any of the kills I had during the war will be among them. Everyone I shot was evil. I had good cause on every shot. They all deserved to die.

No iron chain, or outward force of any kind, could ever compel the soul of man to believe or to disbelieve: it is his own indefeasible light, that judgment of his; he will reign and believe there by the grace of God alone!

I don’t believe in an afterlife, so I don’t have to spend my whole life fearing hell, or fearing heaven even more. For whatever the tortures of hell, I think the boredom of heaven would be even worse.
