The trouble isn't so much that we don't know enough, but it's as if we aren't good enough. The trouble isn't so much that our scientific genius lags behind, but our moral genius lags behind. The great problem facing modern man is that, that the means by which we live have outdistanced the spiritual ends for which we live. So we find ourselves caught in a messed-up world. The problem is with man himself and man's soul. We haven't learned how to be just and honest and kind and true and loving. And that is the basis of our problem. The real problem is that through our scientific genius we've made of the world a neighborhood, but through our moral and spiritual genius we've failed to make of it a brotherhood. And the great danger facing us today is not so much the atomic bomb that was created by physical science. Not so much that atomic bomb that you can put in an aeroplane and drop on the heads of hundreds and thousands of people — as dangerous as that is. But the real danger confronting civilization today is that atomic bomb which lies in the hearts and souls of men, capable of exploding into the vilest of hate and into the most damaging selfishness — that's the atomic bomb that we've got to fear today. Problem is with the men. Within the heart and the souls of men. That is the real basis of our problem.

The great problem of our time is moral, intellectual, and spiritual. With a superfluity of goods we are sinking into poverty. With a multitude of gadgets we are no happier than we were before. With a declining death rate we have yet to discover what to do with our lives. With a hatred of war we are now deeply engaged in the greatest war in history. With a love of liberty we see much of the world in chains.

I keep having the same experience and keep resisting it every time. I do not want to believe it although it is palpable: the great majority of people lack an intellectual conscience. Indeed, it has often seemed to me as if anyone calling for an intellectual conscience were as lonely in the most densely populated cities as if he were in a desert. Everybody looks at you with strange eyes and goes right on handling his scales, calling this good and that evil. Nobody even blushes when you intimate that their weights are underweight; nor do people feel outraged; they merely laugh at your doubts. I mean: the great majority of people does not consider it contemptible to believe this or that and to live accordingly, without first having given themselves an account of the final and most certain reasons pro and con, and without even troubling themselves about such reasons afterward: the most gifted men and the noblest women still belong to this "great majority." But what is goodheartedness, refinement, or genius to me, when the person who has these virtues tolerates slack feelings in his faith and judgments and when he does not account the desire for certainty as his inmost craving and deepest distress--as that which separates the higher human beings from the lower.
