At least from the time of Socrates, in whose ideal state philosophers would be kings, the appeal to the right man has played a major role in systematic reflections on the control of power. For if the right man does rule, Socrates argued, neither institutional nor other controls—e.g., law—need to be employed. Because he is the right man, he will do the right things: he will rule wisely; he will establish or, where already established, he will perpetuate, that order in human affairs that best approximates or achieves justice and secures liberty.
The problem, then, for those who hold this view in democratic states, is not whether the right man should rule, but how he is to be discovered and how he can be assured the reins of political power. Or, to formulate the problem in negative terms, how can we identify and exclude from power those who are the “wrong” men, those who are likely to rule badly and unjustly, those who—because they are, for example, “authoritarians” at heart—may if they achieve positions of power violate the very principles of the democratic state and thereby endanger its existence?
