One of the principal lessons of our tragic century, which has seen so many millions of innocent lives sacrificed in schemes to improve the lot of humanity, is—beware intellectuals. Not merely should they be kept well away from the levers of power, they should also be objects of particular suspicion when they seek to offer collective advice. Beware committees, conferences and leagues of intellectuals. Distrust public statements issued from their serried ranks. Discount their verdicts on political leaders and important events. For intellectuals, far from being highly individualistic and non-conformist people, follow certain regular patterns of behavior. Taken as a group, they are often ultra-conformist within the circles formed by those whose approval they seek and value. This is what makes them, en masse, so dangerous, for it enables them to create climates of opinion and prevailing orthodoxies, which themselves often generate irrational and destructive courses of action. Above all, we must at all times remember what intellectuals habitually forget: that people matter more than concepts and must come first. The worst of all despotisms is the heartless tyranny of ideas.
