Haidt, J. & Kesebir, S. (2010) Morality – available here
I particularly liked this definition of morality
Moral systems are interlocking sets of values, virtues, norms, practices, identities, institutions, technologies, and evolved psychological mechanisms that work together to suppress or regulate selfishness and make cooperative social life possible.
I also found the following statement very interesting in light of the libertarian “No force, no fraud”:
This way of thinking (morality = not harming or cheating others) has become a kind of academic common sense, an assumption shared widely by educated secular people.
