From Chapter 2 of The Constitution of Liberty:
“The rationalist who desires to subject everything to human reason is thus faced with a real dilemma. The use of reason aims at control and predictability. But the process of the advance of reason rests on freedom and the unpredictability of human action. Those who extol the powers of human reason usually see only one side of that interaction of human thought and conduct in which reason is at the same time used and shaped. They do not see that, for advance to take place, the social process from which the growth of reason emerges must remain free from its control.
There can be little doubt that man owes some of his greatest successes in the past to the fact that he has not been able to control social life. His continued advance may well depend on his deliberately refraining from exercising controls which are now in his power. In the past, the spontaneous forces of growth, however much restricted, could usually still assert themselves against the organized coercion of the state. With the technological means of control now at the disposal of government, it is not certain that such assertion is still possible; at any rate, it may soon become impossible. We are not far from the point where the deliberately organized forces of society may destroy those spontaneous forces which have made advance possible.”
