Faith enables many of us to endure life's difficulties with an equanimity that would be scarcely conceivable in a world lit only by reason.

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.

There's no way to reconcile Islam with Christianity. This difference of opinion admits of compromise as much as a coin toss does.

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.

Despite a full century of scientific insights attesting to the antiquity of the earth, more than half of our neighbors believe that the entire cosmos was created six thousand years ago. This is, incidentally, about a thousand years after the Sumerians invented glue.

It is rather more noble to help people purely out of concern for their suffering than it is to help them because you think the Creator of the Universe wants you to do it, or will reward you for doing it, or will punish you for not doing it. The problem with this linkage between religion and morality is that it gives people bad reasons to help other human beings when good reasons are available.

An argument can be logically valid, but unsound in that it contains a false premise and, therefore, leads to a false conclusion (e.g., Scientists are smart; smart people do not make mistakes; therefore, scientists do not make mistakes).
