Evolution is a fact, as securely established as any in science, and he who denies it betrays woeful ignorance and lack of education, which likely extends to other fields as well.

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.

Who loves me will love my dog also.

You're off the edge of the map, mate. Here there be monsters.

I like to travel by myself.

I've never deprived myself of anything. I've always thought if you need to lose weight, carry on eating what you like, just eat less. I don't agree with doing without pasta or bread, it's too harsh.

I love physics with all my heart ... It is a kind of personal love, as one has for a person to whom one is grateful for many things.

Circumstances make man, not man circumstances.

More than fifty-five years ago my father told me, "The Bible does not belong on the shelf but in your hand, under your eye, and in your heart."

Live by faith, not by sight.

That's how you know you really trust someone, I think; when you don't have to talk all the time to make sure they still like you or prove that you have interesting stuff to say.

Only on the cross do you have a totally holy God and a totally loving God.
