“But there is nothing in biology yet found that indicates the inevitability of death.”

That’s the trouble with not being in your own field: You don’t take it seriously.

Innovation is a very difficult thing in the real world

Philosophy of science is about as useful to scientists as ornithology is to birds.

If you thought that science was certain – well, that is just an error on your part.

The things that mattered were honesty, independence, willingness to admit ignorance.

Of course, you only live one life, and you make all your mistakes, and learn what not to do, and that’s the end of you.

I always do that, get into something and see how far I can go.

There are thousands of years in the past, and there is an unknown amount of time in the future. There are all kinds of opportunities, and there are all kinds of dangers.

What I cannot create, I do not understand.

Science is what we have learned about how to keep from fooling ourselves.

Science is the organized skepticism in the reliability of expert opinion.

For a successful technology, reality must take precedence over public relations, for nature cannot be fooled.

Nobody ever figures out what life is all about, and it doesn’t matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough.

The first principle is that you must not fool yourself and you are the easiest person to fool.

I have no responsibility to live up to what others expect of me. That’s their mistake, not my failing.

The only way you can become a legend is in your coffin

The death of one is a tragedy, but death of a million is just a statistic.

Before a man dies, hold back and call him not happy but lucky.

Great deeds are usually wrought at great risks.

Men dislike being awakened from their death in life.

I’d marry again if I found a man who had fifteen million dollars, would sign over half to me, and guarantee that he’d be dead within a year.

Treason seldom dwells with courage.

When life is so burdensome death has become a sought after refuge.
