One of the worst things about breaking the law is that it puts one at odds with an indeterminate number of other people. This is among the many corrosive effects of having unjust laws: They tempt peaceful and (otherwise) honest people to lie so as to avoid being punished for behavior that is ethically blameless.

My concern with religion is that it allows us by the millions to believe what only lunatics or idiots could believe on their own. That's not to say that all religious people are lunatics or idiots. It's anything but that.

We are now in the 21st century: all books, including the Koran, should be fair game for flushing down the toilet without fear of violent reprisal.

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.

How can we encourage other human beings to extend their moral sympathies beyond a narrow locus? How can we learn to become mere human beings, shorn of any more compelling national, ethnic, or religious identity? We can be reasonable. It is in the very nature of reason to fuse cognitive and moral horizons. Reason is nothing less than the guardian of love.

There is no question but that nominally religious scientists like Francis Collins and Kenneth R. Miller are doing lasting harm to our discourse by the accommodations they have made to religious irrationality.

The truth is that we simply do not know what happens after death.
