Each member of society can have only a small fraction of the knowledge possessed by all, and...each is therefore ignorant of most of the facts on which the working of society rests...civilization rests on the fact that we all benefit from knowledge which we do not possess. And one of the ways in which civilization helps us to overcome that limitation on the extent of individual knowledge is by conquering intelligence, not by the acquisition of more knowledge, but by the utilization of knowledge which is and which remains widely dispersed among individuals.
