Plato taught us to be suspicious of any political theory void of moral underpinnings and, a fortiori, of any political theorist offering the appearance of a moral Philistine. The lesson was well learned by political theorists (though by comparably few others) and has contributed to the view that basic political concepts (eg. legitimacy, obligation, and rights) are at root moral concepts. This view, transformed into a methodological imperative, has in turn given rise to the commonplace strategy of criticizing political theorists by claiming either that the institutions or practices which they advocate are not Justifiable given their espoused moral theories or, more radically, that the moral theories to which they subscribe are unacceptable and, because of this, their political conclusions are to be rejected. Should the theorist have no (relatively) obvious and easily compartmentalized moral views whatsoever, he is deemed unworthy of his title - his license to theorize is revoked.
