It is my belief, based partly on personal experience but partly also arrived at by looking around at others, that childhood lasts considerably longer in the males of our species than in the females.

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.

Beware of those who are too focused with polishing and beautifying their outer shells. They lack true substance to understand that genuine beauty is reflected from the heart that resides inside.

Self-confidence is a great faith.

I love all trees, but I am in love with pines.

[My works are] an imitation of my own past and present and of my own creative vitality as I experience them in one particular instant of my emotional and imaginative life. . .

Wolverine was created in the '60s, but he feels like a '70s character in every way. More Dirty Harry, more politically incorrect, the hair, the mutton chops.

Every time I do a movie where it gets physical, I say never again.

Age shall not weary them, nor the years condemn.

That morning she pours Teacher's over my belly and licks it off. That afternoon she tries to jump out the window.

I always stay in the urban comedy genre because it just never gets old. It's one of those things that people watch, again and again. This is that kind of movie. It gives you longevity.

Religions do a useful thing: they narrow God to the limits of man. Philosophy replies by doing a necessary thing: it elevates man to the plane of God.
