I've heard the terms 'moral' and 'morality' thrown around often and what irks me is that it is assumed that these must flow from some kind of religious foundation. So it was heartening to read Steven Pinker's article The Moral Instinct in the New York Times yesterday. It's a fairly long article and just about all of it is quotable so I'd suggest just going there and reading it from beginning to end. It talks about what we perceive as moral, why we do so, how the 'moral sense' can be tricked, and how it evolves as we adapt to changes in our world. It's a very interesting read that will probably surprise, interest, and possibly upset you, all for good reason. I'll be looking into his books in the mean time - I've spotted a few titles that sound like they'd flesh out my own research into language rather well.
