Spiritual life can certainly follow the pattern one sees in the fake martial arts, with most teachers making nebulous and magical claims that never get tested, while their students derange themselves with weird ideas, empty rituals, and other affectations.

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.

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.

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 difference between science and religion is the difference between a willingness to dispassionately consider new evidence and new arguments , and a passionate unwillingness to do so.

We have a choice. We have two options as human beings. We have a choice between conversation and war. That's it. Conversation and violence. And faith is a conversation stopper.

Consider it: every person you have ever met, every person will suffer the loss of his friends and family. All are going to lose everything they love in this world. Why would one want to be anything but kind to them in the meantime?
