Haidt offers (on page 274),this definition of "moral systems":
"Moral systems are interlocking sets of values, virtues, norms, practices, identities, institutions, technologies, and evolved psychological mechanisms that work together to suppress or regulate self-interest and make cooperative societies possible."
I feel moved to respond: No. This is not how I like to use the concept "self-interest." I have a chapter on this in
ETHICS: A College Course. [Click on the second item referenced in the link in the signature below.] Allow me to explain.
Cooperation for the common good IS in our self-interest ! When we reflect on that thought, focus on it, believe it, and live it, we realize that there is no need 'to suppress,' nor 'to regulate' our self-interest. We will discover, though, that our
selfishness - and our
self-centeredness - have been drastically reduced
.You see the distinctions I am drawing? It would be best, I argue, to use the term "selfishness" when we mean a self-aggrandizing kind of self-interest, and reserve the term "self-interest" to mean a good and natural human trait (almost synonymous with the longer, more-unwieldy phrase: enlightened self-interest.) E.g., "When we know our self-interest we will vote for sincerely ethical candidates for public office."
I have a disagreement with Haidt in his choice of words, and it may not be merely a stylistic matter. For purposes of building a good theory of Ethics we ought be very careful in our use of words.
I am not far apart from Haidt in his view that one of the benefits of an ethical system is to help make society function better. When we cooperate on a worthwhile goal we are all better off
