This is the true horror of religion. It allows perfectly decent and sane people to believe by the billions, what only lunatics could believe on their own.

Hope is easy; knowledge is hard. Science is the one domain in which we human beings make a truly heroic effort to counter our innate biases and wishful thinking. Science is the one endeavor in which we have developed a refined methodology for separating what a person hopes is true from what he has good reason to believe.

The atheist, by merely being in touch with reality, appears shamefully out of touch with the fantasy life of his neighbors.

If our well-being depends upon the interaction between events in our brains and events in the world, and there are better and worse ways to secure it, then some cultures will tend to produce lives that are more worth living than others; some political persuasions will be more enlightened than others; and some world views will be mistaken in ways that cause needless human misery.

It is time we realize that belief is not a private matter. As a man believes, so he will act. Believe that you are a member of a chosen people, awash in the salacious exports of an evil culture that is turning your children away from God, believe that you will be rewarded with an eternity of unimaginable delights by dealing death to these infidels—and flying a plane into a building is only a matter of being asked to do it.

Islam, at the moment, is the motherlode of bad ideas.

What would our world be like if we ceased to worry about 'right' and 'wrong,' or 'good' and 'evil,' and simply acted so as to maximize well-being, our own and that of others? Would we lose anything important?
