The crisis in the world is not economic, military, or political; essentially, it is a moral crisis. It is a reflection of man's growing inhumanity to man, which finds its most horrible expression in the total destruction now made possible by the H-bomb. I believe our problem is a reflection of the fact that there is a growing and most serious moral and cultural gap between the progress we have made as a people in the physical sciences, and our lack of progress in the human and social sciences. We know much better how to work with the machines than we know how to live with people.
