All societies are patterned on either a dominator model—in which human hierarchies are ultimately backed up by force or the threat of force—or a partnership model, with variations in between. Moreover, if we reexamine human society from a perspective that takes into account both women and men, we can also see that there are patterns, or systems configurations, that characterize dominator, or alternatively, partnership, social organization.
