[Aldous Huxley] compared the brain to a 'reducing valve'. In ordinary perception, the senses send an overwhelming flood of information to the brain, which the brain then filters down to a trickle it can manage for the purpose of survival in a highly competitive world. Man has become so rational, so utilitarian, that the trickle becomes most pale and thin. It is efficient, for mere survival, but it screens out the most wondrous part of man's potential experience without his even knowing it. We're shut off from our own world.

I think of evolution as a myth, like the Norse myths, the Greek myths - anybody's myths. But it was created for a rational age.

I was sitting in my office when someone called to tell me two light planes had collided with the World Trade Centre. I turned on my television, before long there was this procession of people of all kinds, walking up the street. What I remember most was the silence of that crowd; there was no sound.

My entire career, in fiction or nonfiction, I have reported and written about people who are not like me.

If you label it this, then it can't be that.

And - of course! - the Non-people. The whole freaking world was full of people who were bound to tell you they weren't qualified to do this or that but they were determined to go ahead and do just that thing anyway.

It's fortunate that I am a writer, because that has helped me understand the properties of words. They are what have made life complex. In the battle for status in the animal kingdom, power and aggressiveness have been all-important. But among humans, once they acquired speech, all that changed.
