It is in our collective behavior that we are most mysterious.

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.

In real life, every field of science is incomplete, and most of them - whatever the record of accomplishment during the last 200 years - are still in their very earliest stages.

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.

Animals have genes for altruism, and those genes have been selected in the evolution of many creatures because of the advantage they confer for the continuing survival of the species.

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

The stars do not shine but in the darkness

Before God put that dream into you, he did not ask for the approval of anybody... It means anyone who tells you "it's impossible" is not from God!

Change what you can, accept what you can’t, and be smart enough to know the difference

What you misplace today, will misplace you tomorrow

To fish in troubled waters.

Do not always prove yourself to be the one in the right. The right will appear. You need only give it a chance.

I have no words alas! to tell the loveliness of loving well

I am fully conscious that a complete presentation of the regions visited is a task beyond my power. All I can strive to do is convey an illusion-my own illusion

Occasionally God rips aside the veil, and you begin to see this very fact: All things happen for you. All things. Everything is knit together.

I don't think one parent can raise a child. I don't think two parents can raise a child. You really need the whole village.
