But there are limits to what even knowledge can accomplish, as any psychologist will tell you. Knowledge alone is not enough to redeem life from folly and to save men from despair. If it ever was, it is no longer valid to assume that learning’s supreme glory is in the safeguarding of humanity, the dispelling of prejudice, and the achieving of those moral values that are said to have inspired men of other ages. Perhaps I am deeply pessimistic, but I simply cannot believe that if only people knew enough of the what, the why and the how, all would be right with the world. Knowledge does not ensure moral behavior; it all too willingly puts itself at the service of despotism and inhumanity. I suppose that what is lacking in our modern learning and among our modern learned is a sense that morality is the product of human experience—that it comes, anciently out of a wisdom we have forgotten, from a realization of the character of human life. Certainly the moralistic approach to human relations in general and to race relations in particular in America has failed so consistently that one mentions this approach with embarrassment and reluctance. It is considered namby-pamby, pusillanimous, Uncle-Tomish. Few, even of the ministers of the gospel, appeal to nobility and virtue and goodness any more, except as these qualities seem disingenuously to be connected with “practical concerns.” We no longer think of great men as being great in those virtuous qualities to which former and simpler ages subscribed. Those moral excellencies—love, honor, truth—seem to many ordinary people “a long way removed from our normal affairs.” Great men today are “practical-minded,” “realistic” and “public-spirited,” and none of these attributes, I take it, is necessarily virtuous. To be trite about it, any one of them can cover a multitude of evils. The realistic attitude has been the excuse for innumerable travesties of human rights; in the name of public spirit heinous crimes have been committed against the dignity of man; and too many politicians and diplomats have made practical-mindedness the inviolable sanction for the suppression of the worthy ambitions of the powerless.
