It is not realistic or hardheaded to solve problems and take action unguided by ultimate moral aims and values, although we all know some who claim that it is so. In my judgment, it is thoughtless folly. For it ignores the realities of human faith and of passion and of belief - forces ultimately more powerful than all of the calculations of our economists or of our generals. Of course to adhere to standards, to idealism, to vision in the face of immediate dangers takes great courage and takes self-confidence. But we also know that only those who dare to fail greatly, can ever achieve greatly.
