Everyone who has eyes to see can see that if the God of Abraham exists, He is an utter psychopath--and the God of Nature too. If you can't see these things just by looking, you have simply closed your eyes to the realities of our world.

Science has long been in the value business. Despite a widespread belief to the contrary, scientific validity is not the result of scientists abstaining from making value judgments; rather, scientific validity is the result of scientists making their best efforts to value principles of reasoning that link their beliefs to reality, through reliable chains of evidence and argument.

In the year 2006, a person can have sufficient intellectual and material resources to build a nuclear bomb and still believe that he will get seventy-two virgins in Paradise.

The moral landscape is the framework I use for thinking about questions of morality and human values in universal terms.

We know enough at this moment to say that the God of Abraham is not only unworthy of the immensity of creation; he is unworthy even of man.

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.

People who harbor strong convictions without evidence belong at the margins of our societies, not in our halls of power. The only thing we should respect in a person’s faith is his desire for a better life in this world; we need never have respected his certainty that one awaits him in the next.
