We do not know what awaits each of us after death, but we know that we will die. Clearly, it must be possible to live ethically-with a genuine concern for the happiness of other sentient beings-without presuming to know things about which we are patently ignorant. Consider it: every person you have ever met, every person you will pass in the street today, is going to die. Living long enough, each will suffer the loss of his friends and family. All are going to lose everything they love in this world. Why would one want to be anything but kind to them in the meantime?

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

Imagine a world in which generations of human beings come to believe that certain films were made by God or that specific software was coded by him. Imagine a future in which millions of our descendants murder each other over rival interpretations of Star Wars or Windows 98. Could anything -- anything -- be more ridiculous? And yet, this would be no more ridiculous than the world we are living in.

When considering the truth of a proposition, one is either engaged in an honest appraisal of the evidence and logical arguments, or one isn't. Religion is one area of our lives where people imagine that some other standard of intellectual integrity applies.

Just as there is no such thing as Christian physics or Muslim Algebra, we will see tht there is no such thing as Christian or Muslim morality.

Religious faith obscures uncertainty where uncertainty . . . exists, allowing the unknown, the implausible, and the . . . false to achieve primacy over the facts.

Unreason is now ascendant in the United States - in our schools, in our courts, and in each branch of the federal government. Only 28 percent of Americans believe in evolution; 68 percent believe in Satan. Ignorance in this degree, concentrated in both the head and belly of a lumbering superpower, is now a problem for the entire world.
