The most obvious example of power-morality is the inculcation of obedience. It is (or rather was) the duty of children to submit to parents, wives to husbands, servants to masters, subjects to princes, and (in religious matters) laymen to priests; there were also more specialized duties of obedience in armies and religious orders. Each of these duties has a long history, running parallel with that of the institution concerned.
