“One of the main purposes of university education is to escape from the Zeitgeist, from the mean, narrow, provincial spirit which is constantly assuring us that we are at the peak of human achievement, that we stand on the edge of unprecedented prosperity or an unparalleled catastrophe; that the next summit conference is going to be the most fateful in history or that the leader of the day is either the greatest, or the most disastrous, of all time. It is a liberation of the spirit to acquire perspective, to recognize that every generation is confronted by problems of the utmost subjective urgency, but that an objective grading is probably impossible; to learn that the same moral predicaments and the same ideas have been explored before. One need read very little in political theory to become aware of recurrences and repetitions.”
