It is true that the masses have always been led in one manner or another, and it could be said that their part in history consists primarily in allowing themselves to be led, since they represent a merely passive element, a matter in the Aristotelian sense of the word. But, to lead them today, it is sufficient to dispose of purely material means, … and this shows clearly to what depths our age has sunk. At the same time the masses are made to believe that they are not being led, but that they are acting spontaneously and governing themselves, and the fact that they believe this is a sign from which the extent of their stupidity may be inferred.
