Austin: This article was pretty engaging more me, although skip over the first half or so unless you want a very short "history" of failed moral arguments. The second half is what I found myself more engaged by. I'm curious what people think of his concluding paragraph where he discusses that it is difficult to find objective grounds for our emotional responses, and that if we can't then the conclusion is that we're simply culturally prejudice. Is that the automatic result of not being able to prove something objectively? Is there no middle ground?
