It is a dangerous and idle dream to think that the state can become rule by philosophers turned kings or scientists turned commissars. For if philosophers become kings or scientists commissars, they become politicians, and the powers given to the state are powers given to men who are rulers of states, men subject to all the limitations and temptations of their dangerous craft. Unless this is borne in mind, there will be a dangerous optimistic tendency to sweep aside doubts and fears as irrelevant, since, in the state that the projectors have in mind, power will be exercised by men of a wisdom and degree of moral virtue that we have not yet seen. It won't. It will be exercised by men who will be men first and rulers next and scientists and saints long after.
