The present Luddism over genetic engineering may die a natural death as the computer-illiterate generation is superseded.... I fear that, if the green movement's high-amplitude warnings over GMOs turn out to be empty, people will be dangerously disinclined to listen to other and more serious warnings.

I think that's the mother and father of all cop-outs. It's an honest scientific quest to discover where this apparent improbability comes from. Now [Francis] Collins says, "Well, God did it. And God needs no explanation because God is outside all this." Well, what an incredible evasion of the responsibility to explain. Scientists don't do that. Scientists say, "We're working on it. We're struggling to understand."

When we started out and we were talking about the origins of the universe and the physical constants, I provided what I thought were cogent arguments against a supernatural intelligent designer. But it does seem to me to be a worthy idea.

Suffering is a byproduct of evolution by natural selection, an inevitable consequence that may worry us in our more sympathetic moments but cannot be expected to worry a tiger - even if a tiger can be said to worry about anything at all - and certainly cannot be expected to worry its genes.

When we talk about genes for anything, like a gene for being gay or a gene for being aggressive or something of that sort, that a gene for anything may not have been a gene for that thing under different environmental conditions.

You could give Aristotle a tutorial. And you could thrill him to the core of his being. Aristotle was an encyclopedic polymath, an all time intellect. Yet not only can you know more than him about the world, you also can have a deeper understanding of how everything works. Such is the privilege of living after Newton, Darwin, Einstein, Planck, Watson, Crick and their colleagues.

There's real poetry in the real world. Science is the poetry of reality.
