"America's progress in the years ahead depends on the American thinking of today. This is an extremely important point, because progress, or lack of it, at any given time depends on what is happening in the minds of men and women at some previous time. Thus, the long range prospects of our nation depend, not on the older folks, but on the thinking of the younger people who will be at the helm 10 years, 20 years, 30, 40, 50 years hence. One of the best ways to insure future progress is to keep clearly in mind the things which have been responsible for our past progress. It is important that we do not forget. When we do forget, there is a temptation to indulge in wishful thinking - to build imaginative Utopias on the basis of things as we might like them to be, instead of facing the real human situation and reckoning with things as they are."
