We have yet to learn how to retain our humaneness when assembled in masses.

It is from the progeny of this parent cell that we all take our looks; we still share genes around, and the resemblance of the enzymes of grasses to those of whales is in fact a family resemblance.

The capacity to blunder slightly is the real marvel of DNA. Without this special attribute, we would still be anaerobic bacteria and there would be no music.

Statistically, the probability of any one of us being here is so small that you'd think the mere fact of existing would keep us all in a contented dazzlement of surprise.

We owe our lives to the sun... How is it, then, that we feel no gratitude?

The greatest single achievement of nature to date was surely the invention of the molecule DNA.

It is in our genes to understand the universe if we can, to keep trying even if we cannot, and to be enchanted by the act of learning all the way.

I would send the complete works of Johann Sebastian Bach into outer space on the Voyager spacecraft. But that would be boasting.

We leave traces of ourselves wherever we go, on whatever we touch.

The best you can offer is to be for God, the good you can do is to help fellow human beings and the result of this can be to greatness with sincerity together with integrity.

Teeth aren't pearly, until you smile.

To talk of diseases is a sort of Arabian Nights entertainment.

Family: a foundation! Family: a ‘cloth’ that keeps the ‘body’!

Every man is a volume if you know how to read him.

I'm pretty klutzy and I've always been, so I have to own up to it. It's part of my charm!

It is insane that two men, sitting on opposite sides of the world, should be able to decide to bring an end to civilization.

I'm an immigrant and I will stay an immigrant forever.

When I started on Wall Street, there was pretty good diversity in those junior ranks. And you know what? It hasn't made it to the top.
