As Atrios would say: please, make it stop!

I had in mind experts of many different types, not all specialists in a particular field. Following Plato, I envisage people trained in all subjects relevant to politics--history, geography, philosophy, psychology, etc. These would be the "philosopher kings" (though not our narrow sense of "philosophy"). They could have advisors in a specific field, if necessary, but they would be broadly educated. These experts would work with some democraticlly elected leaders to make policy--but not merely in an advisory capacity.

Can there be such a thing as the rump avant-garde?
