““Does that mean that religious texts are worthless as guides to ethics? Of course not. They are magnificent sources of insight into human nature, and into the possibilities of ethical codes. Just as we should not be surprised to discover that ancient folk medicine has a great deal to teach modern hightech medicine, we should not be surprised if we find that these great religious texts hold versions of the very best ethical systems any human culture will ever devise. But, like folk medicine, we should test it all carefully, and take nothing whatever on faith.””
