I hate to be picky, but I'm not sure that evolution can be invoked as an answer to my question about how you know that people are inherently valuable. It works for explaining why you feel that way, but not why you believe that way. In fact, since you know that evolution has programmed you to feel a particular way (because it was advantageous for your ancestors to feel that way) then the rational thing would be to question the rightness of that feeling. It might be rational to doubt that people are inherently valuable (even though you feel it strongly) because of what you know about evolution. But I don't see how it's rational to believe that people are inherently valuable because of what you know about evolution.
I'm going to put myself on the line and admit that I believe (maybe more than anything else) that people are inherently valuable. And that I can't rationally defend that belief at all.
I truly cannot come up with a good response to this. What are your reactions?
