I don't think there's an interesting boundary between philosophy and science. Science is totally beholden to philosophy. There are philosophical assumptions in science and there's no way to get around that.

I think there are universal principles that we should want to understand, but that are not necessarily good for us. We could recognise universal propensities which current cultures can't fully eradicate, which we would want to eradicate if we could. Let's say, a tendency for tribal violence. Or racism.

I was actually already doing my Ph.D. in neuroscience when September 11 happened. 'The End Of Faith' is essentially what September 11 did to my intellectual career at that moment.

In my experience with print journalists, the distinction between remarks being uttered on- or off-the-record is held sacrosanct, but the distinction between truth and falsity sometimes isn't.

It is difficult to think of anything more important than providing the best education possible for our children. They will develop the next technologies, medical cures, and global industries, while mitigating their unintended effects, or they will fail to do these things and consign us all to oblivion.

It is easy to see what many people, women especially, admire about Sarah Palin. Here is a mother of five who can see the bright side of having a child with Down syndrome and still find the time and energy to govern the state of Alaska.

It is still fashionable to believe that how you organize yourself religiously in this life may matter for eternity. Unless we can erode the prestige of that kind of thinking, we're not going to be able to undermine these divisions in our world.

Many of my fellow atheists consider all talk of 'spirituality' or 'mysticism' to be synonymous with mental illness, conscious fraud, or self-deception. I have argued elsewhere that this is a problem - because millions of people have had experiences for which 'spiritual' and 'mystical' seem the only terms available.

Many scientists have been drawn to Buddhism out of a sense that the Western tradition has delivered an impoverished conception of basic, human sanity. In the West, if you speak to yourself out loud all day long, you are considered crazy. But speaking to yourself silently - thinking incessantly - is considered perfectly normal.

Morality must relate, at some level, to the well-being of conscious creatures. If there are more and less effective ways for us to seek happiness and to avoid misery in this world - and there clearly are - then there are right and wrong answers to questions of morality.

Most people believe that the Creator of the universe wrote (or dictated) one of their books. Unfortunately, there are many books that pretend to divine authorship, and each makes incompatible claims about how we all must live.

Most seem to think that while a person may not be responsible for the opportunities he gets in life, each is entirely responsible for what he makes of these opportunities.

Muslim moderates, wherever they are, must be given every tool necessary to win a war of ideas with their co-religionists. Otherwise, we will have to win some very terrible wars in the future.

My concern with religion is that it allows us by the millions to believe what only lunatics or idiots could believe on their own. That's not to say that all religious people are lunatics or idiots. It's anything but that.

Nearly half of the American population is eagerly anticipating the end of the world. This dewy-eyed nihilism provides absolutely no incentive to build a sustainable civilization. Many of these people are lunatics, but they are not the lunatic fringe.

Nothing guarantees that reasonable people will agree about everything, of course, but the unreasonable are certain to be divided by their dogmas. It is time we recognized that this spirit of mutual inquiry, which is the foundation of all real science, is the very antithesis of religious faith.

On the subject of religious belief, we relax standards of reasonableness and evidence that we rely on in every other area of our lives. We relax so totally that people believe the most ludicrous propositions, and are willing to organize their lives around them.

One of the great responsibilities we have as a society is to educate ourselves, along with the next generation, about which substances are worth ingesting, and for what purpose, and which are not.

Positive social emotions like compassion and empathy are generally good for us, and we want to encourage them. But do we know how to most reliably raise children to care about the suffering of other people? I'm not sure we do.

Religion has convinced us that there's something else entirely other than concerns about suffering. There's concerns about what God wants, there's concerns about what's going to happen in the afterlife.
