It is a virtue to admit ignorance when you don't know, but not to wallow in ignorance as an end in itself. People say if we don't believe god is watching over us, we abandon morality. Are they right?

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.

When we are anxious about what is going to happen next, we are not staying in our now!

His moral lectureblazed with hate.What could have driven a child that far?

Degeneracy follows every autocratic system of violence, for violence inevitably attracts moral inferiors. Time has proven that illustrious tyrants are succeeded by scoundrels.

One can believe intellectually in the efficacy of prayer and never do any praying.

You have to keep practicing, if you're really going to be good.

People have a natural tendency to read emotions out of faces, so when you see a face that is hyperreal but without the life behind the eyes, it's really off-putting and intriguing.

The entrepreneur must be the best salesperson and marketer in his business.

When you're a kid, you just have no concept of anything other than what you're doing.

What I'm advocating is an intellectual revolution - it's a different mindset concerning the ethical benchmarks by which we live.

Business is really more agreeable than pleasure; it interests the whole mind, the aggregate nature of man more continuously, and more deeply. But it does not look as if it did.
