I'm fond of science fiction. But not all science fiction.

Much as we might wish to believe otherwise, universal love and the welfare of the species as a whole are concepts which simply do not make evolutionary sense.

Do not indoctrinate your children. Teach them how to think for themselves, how to evaluate evidence, and how to disagree with you.

Faith is belief without evidence and reason; coincidentally that's also the definition of delusion.

Evolution is just a theory? Well, so is gravity and I don't see you jumping out of buildings.

Such delusions of grandeur to think that a God with a hundred billion galaxies on his mind would give a tuppenny damn who you sleep with, or indeed whether you believe in him.

The less you think, the more you believe.

How thoughtful of God to arrange matters so that, wherever you happen to be born, the local religion always turns out to be the true one.

The universe we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil, no good, nothing but blind, pitiless indifference.

Science is the poetry of reality.

The theory of evolution by cumulative natural selection is the only theory we know of that is in principle capable of explaining the existence of organized complexity.

Service is a balm to both the spirit and the body.

The hand that wields the knife shall never wear the crown.

I look at autism like a bus accident, and you don't become cured from a bus accident, but you can recover.

Knowledge is the consequence of time, and multitude of days are fittest to teach wisdom.

I've always had this female-empowerment thing in the back of my mind - because I wanted my mother to be stronger, and she couldn't be. I thought, 'If I'm successful, I can change her life.'

...there are no natural borderlines in evolution. The illusion of a borderline is created by the fact that the evolutionary intermediates happen to be extinct.

If anything, there's more at stake when you're older, and more responsibility and more legitimate things to worry about.

Winning starts with beginning.

But presidents matter. That's one of the biggest lessons I learned being in the White House.

The man for whom time stretches out painfully is one waiting in vain, disappointed at not finding tomorrow already continuing yesterday.
