Advance warning of Katrina's path was wrested from mute Nature by meteorological calculations and satellite imagery. God told no one of His plans. Had the residents of New Orleans been content to rely on the beneficence of God, they wouldn't have known that a killer hurricane was bearing down upon them until they felt the first gusts of wind on their faces. And yet, as will come as no surprise to you, a poll conducted by The Washington Post found that 80 percent of Katrina's survivors claim that the event only strengthened their faith in God.

The fact that one can lose one's sense of self in an ocean of tranquility does not mean that one's consciousness is immaterial or that it presided over the birth of the universe.

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

I consistently encounter people in academic settings and scientists and journalists who feel that you can't say that anyone is wrong in any deep sense about morality, or with regard to what they value in life. I think this doubt about the application of science and reason to questions of value is really quite dangerous.

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.

Life is a continuous flux. Our nonhuman ancestors bred, generation after generation, and incrementally begat what we now deem to be the species homo sapiens - ourselves. There is nothing about our ancestral line or about our current biology that dictates how we will evolve in the future. Nothing in the natural order demands that our descendants resemble us in any particular way. Very likely, they will not resemble us. We will almost certainly transform ourselves, likely beyond recognition, in the generations to come.

You can do what you decide to do — but you cannot decide what you will decide to do.
