The deity who stalked the deserts of the Middle East millennia ago-and who seems to have abandoned them to bloodshed in his name ever since-is no one to consult on questions of ethics.

By lying, we deny others a view of the world as it is. Our dishonesty not only influences the choices they make, it often determines the choices they can make—and in ways we cannot always predict. Every lie is a direct assault upon the autonomy of those we lie to.

While believing strongly, without evidence, is considered a mark of madness or stupidity in any other area of our lives, faith in God still holds immense prestige in our society. Religion is the one area of our discourse where it is considered noble to pretend to be certain about things no human being could possibly be certain about. It is telling that this aura of nobility extends only to those faiths that still have many subscribers. Anyone caught worshipping Poseidon, even at sea, will be thought insane.

Nothing guarantees that reasonable people will agree about everything, of course, but the unreasonable are certain to be divided by their dogmas. It is time we recognized that this spirit of mutual inquiry, which is the foundation of all real science, is the very antithesis of religious faith.

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.

Unlike statements of fact, which require no further work on our part, lies must be continually protected from collisions with reality.

You can't take credit for your talents, but it matters that you use them. You can't really be blamed for your weaknesses, but it matters that you correct them. So pride and shame don't make a lot of sense, in the final analysis, but they weren't much fun anyway.
