Friedrich Hayek

The publication of two books … helped to galvanize the concerns that were beginning to emerge among intellectuals (and many others) about the implications of totalitarianism. One was James Burnham's The Managerial Revolution … [A second] Friedrich A. Hayek's The Road to Serfdom … was far more controversial — and influential. Even more than Burnham, Hayek forced into public discourse the question of the compatibility of democracy and statism. And unlike Burnham, he made no pretense of neutrality about the phenomena he described. … In responding to Burnham and Hayek … liberals were in fact responding to a powerful strain of Jeffersonian anti-statism in American political culture … The result was a subtle but important shift in liberal thinking.

The social sciences, like much of biology but unlike most fields of the physical sciences, have to deal with structures of essential complexity, i.e. with structures whose characteristic properties can be exhibited only by models made up of relatively large numbers of variables. Competition, for instance, is a process which will produce certain results only if it proceeds among a fairly large number of acting persons.

Friedrich Hayek, who died on March 23, 1992 at age 92, was arguably the greatest social scientist of the twentieth century. By the time of his death, his fundamental way of thought had supplanted the system of John Maynard Keynes — his chief intellectual rival of the century — in the battle since the 1930s for the minds of economists and the policies of governments."

The conservative feels safe and content only if he is assured that some higher wisdom watches and supervises change, only if he knows that some authority is charged with keeping the change "orderly."

Conservatism, though a necessary element in any stable society, is not a social program; in its paternalistic, nationalistic and power adoring tendencies it is often closer to socialism than true liberalism; and with its traditionalistic, anti-intellectual, and often mystical propensities it will never, except in short periods of disillusionment, appeal to the young and all those others who believe that some changes are desirable if this world is to become a better place.

The first proponent of cortical memory networks on a major scale was neither a neuroscientist nor a computer scientist but … a Viennes economist: Friedrich von Hayek (1899-1992). A man of exceptionally broad knowledge and profound insight into the operation of complex systems, Hayek applied such insight with remarkable success to economics (Nobel Prize, 1974), sociology, political science, jurisprudence, evolutionary theory, psychology, and brain science (Hayek, 1952)."

Information costs are reduced by the existence of large numbers of buyers and sellers. Under these conditions, prices embody the same information that would require large search costs by individual buyers and sellers in the absence of an organized market. (footnote 4: The original contributions were those of Hayek (1937 and 1945)).

In the physical sciences there may be little objection to trying to do the impossible; one might even feel that one ought not to discourage the over-confident because their experiments may after all produce some new insights. But in the social field the erroneous belief that the exercise of some power would have beneficial consequences is likely to lead to a new power to coerce other men being conferred on some authority. Even if such power is not in itself bad, its exercise is likely to impede the functioning of those spontaneous ordering forces by which, without understanding them, man is in fact so largely assisted in the pursuit of his aims.

Conservatives feel instinctively that it is new ideas more than anything else that cause change. But, from its point of view rightly, conservatism fears new ideas because it has no distinctive principles of its own to oppose them; and, by its distrust of theory and its lack of imagination concerning anything except that which experience has already proved, it deprives itself of the weapons needed in the struggle of ideas. Unlike liberalism, with its fundamental belief in the long-range power of ideas, conservatism is bound by the stock of ideas inherited at a given time. And since it does not really believe in the power of argument, its last resort is generally a claim to superior wisdom, based on some self-arrogated superior quality.

From the saintly and single-minded idealist to the fanatic is often but a step.

My interest in public policy and political philosophy was rather casual before I joined the faculty of the University of Chicago. Informal discussions with colleagues and friends stimulated a greater interest, which was reinforced by Friedrich Hayek's powerful book The Road to Serfdom, by my attendance at the first meeting of the Mont Pelerin Society in 1947, and by discussions with Hayek after he joined the university faculty in 1950. In addition, Hayek attracted an exceptionally able group of students who were dedicated to a libertarian ideology. They started a student publication, The New Individualist Review, which was the outstanding libertarian journal of opinion for some years. I served as an adviser to the journal and published a number of articles in it.

The case for individual freedom rests chiefly on the recognition of the inevitable and universal ignorance of all of us concerning a great many of the factors on which the achievement of our ends and welfare depend. It is because every individual knows so little and, in particular, because we rarely know which of us knows best that we trust the independent and competitive efforts of many to induce the emergence of what we shall want when we see it.
Humiliating to human pride as it may be, we must recognize that the advance and even the preservation of civilization are dependent upon a maximum of opportunity for accidents to happen. These accidents occur in the combination of knowledge and attitudes, skills and habits, acquired by individual men and also when qualified men are confronted with the particular circumstances which they are equipped to deal with. Our necessary ignorance of so much means that we have to deal largely with probabilities and chances.
Of course, it is true of social as of individual life that favorable accidents usually do not just happen. We must prepare for them.

It is largely because civilization enables us constantly to profit from knowledge which we individually do not possess and because each individual's use of his particular knowledge may serve to assist others unknown to him in achieving their ends that men as members of civilized society can pursue their individual ends so much more successfully than they could alone.

The Socratic maxim that the recognition of our ignorance is the beginning of wisdom has profound significance for our understanding of society. Most of the advantages of social life, especially in the more advanced forms that we call 'civilization' rest on the fact that the individual benefits from more knowledge than he is aware of. It might be said that civilization begins when the individual in the pursuit of his ends can make use of more knowledge than he has himself acquired and when he can transcend the boundaries of his ignorance by profiting from knowledge he does not himself possess.

Allow me to define more specifically the inherent limitations of our numerical knowledge which are so often overlooked. I want to do this to avoid giving the impression that I generally reject the mathematical method in economics. I regard it in fact as the great advantage of the mathematical technique that it allows us to describe, by means of algebraic equations, the general character of a pattern even where we are ignorant of the numerical values which will determine its particular manifestation. We could scarcely have achieved that comprehensive picture of the mutual interdependencies of the different events in a market without this algebraic technique. It has led to the illusion, however, that we can use this technique for the determination and prediction of the numerical values of those magnitudes; and this has led to a vain search for quantitative or numerical constants.

If we are to understand how society works, we must attempt to define the general nature and range of our ignorance concerning it.

The key importance of the amount of information available and the frequent lack of relevant information have been dealt with only in the last decades. L. von Mises and F. A. von Hayek can rightly be regarded as pioneers in this connection.

The effect of the people's agreeing that there must be central planning, without agreeing on the ends, will be rather as if a group of people were to commit themselves to take a journey together without agreeing where they want to go; with the result that they may all have to make a journey which most of them do not want at all.

The mind cannot foresee its own advance.

Many economists have professed to analyze information; relatively few have considered carefully the problems of knowledge. Among those who have, Hayek is pre-eminent.
