The characteristic human trait is not awareness but conformity, and the characteristic result is religious warfare. Other animals fight for territory or food; but, uniquely in the animal kingdom, human beings fight for their 'beliefs.' The reason is that beliefs guide behavior, which has evolutionary importance among human beings. But at a time when our behavior may well lead us to extinction, I see no reason to assume we have any awareness at all. We are stubborn, self-destructive conformists. Any other view of our species is just a self-congratulatory delusion.

You know, at times like this one feels, well, perhaps extinct animals should be left extinct.

Exercise invigorates the body and sharpens the mind.

And entertainment has nothing to do with reality. Entertainment is antithetical to reality.

Often I feel I go to some distant region of the world to be reminded of who I really am. There is no mystery about why this should be so. Stripped of your ordinary surroundings, your friends, your daily routines, your refrigerator full of your food, your closet full of your clothes -- with all this taken away, you are forced into direct experience. Such direct experience inevitably makes you aware of who it is that is having the experience. That's not always comfortable, but it is always invigorating.

It is especially difficult for modern people to conceive that our modern, scientific age might not be an improvement over the prescientific period.

The past history of human belief is a cautionary tale. We have killed thousands of our fellow human beings because we believed they had signed a contract with the devil, and had become witches. We still kill more than a thousand people each year for witchcraft. In my view, there is only one hope for humankind to emerge from what Carl Sagan called "the demon-haunted world" of our past. That hope is science.
