Nothing in biology makes sense except in the light of evolution.

The more we know, the better we realize that our knowledge is a little island in the midst of an ocean of ignorance.

Does the evolutionary doctrine clash with religious faith? It does not. It is a blunder to mistake the Holy Scriptures for elementary textbooks of astronomy, geology, biology, and anthropology.

Natural selection must be replaced by eugenical artificial selection. This idea constitutes the sound core of eugenics, the applied science of human betterment.

The living world is not a single array... connected by unbroken series of intergrades.

No evidence is powerful enough to force acceptance of a conclusion that is emotionally distasteful.

Nature's stern discipline enjoins mutual help at least as often as warfare. The fittest may also be the gentlest.

Scientists often have a naive faith that if only they could discover enough facts about a problem, these facts would somehow arrange themselves in a compelling and true solution.

Pat answers to complex problems are the hallmark of intellectual mediocrity

No known human group... simply throw out its dead without any ritual or ceremony. In stark contrast, no animal practices burial of dead individuals of its own species.

An accident, a random change, in any delicate mechanism can hardly be expected to improve it. Poking a stick into the machinery of one's watch or one's radio set will seldom make it work better.

And read… read all the time… read as a matter of principle, as a matter of self-respect. Read as a nourishing staple of life.

It's not so much about what the morning brings

Only the great warriors fall down from their horses

The human race has the power right now to destroy itself. Jesus Christ is going to save us from ourselves.

It's the beautiful minds of this world that win over beautiful faces. They win hearts by winning minds.

Most people do not believe in anything very much and our greatest poetry is given to us by those who do.

I'm 5 foot 2. I wish I were 5' 6. Everyone who meets me says, 'Oh my God. You look so much taller in person.'

Reputation, you know – a lifetime to build, seconds to destroy.

You cannot believe how hard it is to try and raise money for a film. I did it for six years and it was such a failure.

We can’t say why we search, except that there seems to be an innate need, in each human being, to know who one is, what we’re here for, how to live more poetically.
