“Not explaining science seems to me perverse. When you’re in love, you want to tell the world.”

Advances in medicine and agriculture have saved vastly more lives than have been lost in all the wars in history.

We make our world significant by the courage of our questions and the depth of our answers.

Books break the shackles of time, proof that humans can work magic.

The universe is a pretty big place. If it’s just us, seems like an awful waste of space.

The universe is not required to be in perfect harmony with human ambition.

Better the hard truth, I say, than the comforting fantasy.

The price we pay for anticipation of the future is anxiety about it.

We can’t help it. Life looks for life.

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

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.

It’s very hard not to be condescending when you’re explaining something to an idiot.

I can’t explain it, but from the first day I stepped into a wrestling ring, I knew that one day I was going to be a big superstar. I knew that one day I would be the NWA World Heavyweight Champion like my hero, Lou Thesz.

In acting process, it’s very difficult to explain. It’s something very intimate, very private.

To say that the universe was here last year, or millions of years ago, does not explain its origin. This is still a mystery. As to the question of the origin of things, man can only wonder and doubt and guess.

America is like a dog. I’m sorry, but it is. It cannot understand actual words. It understands inflection. It understands fear. But you can’t actually explain issues to a dog.

I was in disbelief that I’d just explained my dreary life to this bizarre, beautiful boy who may or may not despise me.
