Studying Zen made me realize that most of the teachings which people interpret moralistically (or theologically) actually point to a psychological reality.
However, I can't help but feel that a lot of Abrahamic teachings seem to be mostly about increasing the mimetic fitness of the faith. For instance: "go forth and multiply" is always good for keeping the size of your congregation up; evangelism likewise; "you shall not boil a kid in its mother's milk" reads to me as "don't eat your future dairy animals", a handy survival tip in the bronze age; and so forth.
