John Lukacs in The Passing of the Modern Age (1977).
“The sometimes hopeless slowness in the movement of ideas makes life difficult for the young who, even more than adults, are very much dependent upon the ideas of others. This is why the dissolution of learning will not at all eliminate their dependence on teachers, rather the contrary. And the great teachers of the future will be those who, through a kind of wisdom, will direct their attention to all kinds of public untruths, very much including those propagated by the established public intellectuals.”
