“Values reduce to facts about the well-being of conscious creatures.”

To say that I would have done otherwise had I wanted to is simply to say that I would have lived in a different universe had I been in a different universe.

What I’m asking you to entertain is that there is nothing we need to believe on insufficient evidence in order to have deeply ethical and spiritual lives.

Most of us are wiser than we may appear to be. On one level, wisdom is nothing more profound than an ability to follow one’s own advice.

How can we be “free” as conscious agents if everything that we consciously intend is caused by events in our brain that we do not intend and of which we are entirely unaware? We can’t.

The position of the Muslim community in the face of all provocations seems to be: Islam is a religion of peace, and if you say that it isn’t, we will kill you.

Our world is fast succumbing to the activities of men and women who would stake the future of our species on beliefs that should not survive an elementary school education.

Science, in the broadest sense, includes all reasonable claims to knowledge about ourselves and the world.

As a man believes, so he will act.

We will see that the greatest problem confronting civilization is not merely religious extremism: rather, it is the larger set of cultural and intellectual accommodations we have made to faith itself.

I’m the Ted Bundy of string theory.

The problem of vindicating an omnipotent and omniscient God in the face of evil is insurmountable. Those who claim to have surmounted it, by recourse to notions of free will and other incoherencies, have merely heaped bad philosophy onto bad ethics.

Either God can do nothing to stop catastrophes like this, or he doesn’t care to, or he doesn’t exist. God is either impotent, evil, or imaginary. Take your pick, and choose wisely.

Islam, at the moment, is the motherlode of bad ideas.

The truth is that we simply do not know what happens after death.

Unlike statements of fact, which require no further work on our part, lies must be continually protected from collisions with reality.

You don’t get anything worth getting, by pretending to know things you don’t know.

Facts are true whether or not you believe them.

There is always a chance to get even and I’m proud of the fact that for all the blows I always got back up again. That’s what makes me most content.

Mars ain’t the kind of place to raise your kids, in fact it’s cold as hell.

The errors which arise from the absence of facts are far more numerous and more durable than those which result from unsound reasoning respecting true data.

The language of experiment is more authoritative than any reasoning: facts can destroy our ratiocination—not vice versa.

An autobiography can distort; facts can be realigned. But fiction never lies: it reveals the writer totally.

Science, for me, gives a partial explanation for life. In so far as it goes, it is based on fact, experience and experiment.

When the fact doesn’t meet the theory then let go the theory.
