While an equality of rights under a limited government is possible and an essential condition of individual freedom, a claim for equality of material… - F.A. Hayek

This is not the place to discuss how this change in outlook was fostered by the uncritical transfer to the problems of society of habits of thought engendered by the preoccupation with technological problems, the habits of thought of the natural scientist and the engineer, and how these at the same time tended to discredit the results of the past study of society which did not conform to their prejudices and to impose ideals of organization on a sphere to which they are not appropriate.

Complete rationality of action in the Cartesian sense demands complete knowledge of all the relevant facts. A designer or engineer needs all the data and full power to control or manipulate them if he is to organize the material objects to produce the intended result. But the success of action in society depends on more particular facts than anyone can possibly know. And our whole civilization in consequence rests, and must rest, on our believing rnuch that we cannot know to be true in the Cartesian sense.

Morals, including especially, our institutions of property, freedom and justice, are not a creation of man’s reason but a distinct second endowment conferred on him by cultural evolution - runs counter to the main intellectual outlook of the twentieth century. The influence of rationalism has indeed been so profound and pervasive that, in general, the more intelligent an educated person is, the more likely he or she now is not only to be a rationalist, but also to hold socialist views (regardless of whether he or she is sufficiently doctrinal to attach to his or her views any label, including ‘socialist’). The higher we climb up the ladder of intelligence, the more we talk with intellectuals, the more likely we are to encounter socialist convictions. Rationalists tend to be intelligent and intellectual; and intelligent intellectuals tend to be socialist.
One’s initial surprise at finding that intelligent people tend to be socialist diminishes when one realises that, of course, intelligent people will tend to overvalue intelligence, and to suppose that we must owe all the advantages and opportunities that our civilisation offers to deliberate design rather than to following traditional rules, and likewise to suppose that we can, by exercising our reason, eliminate any remaining undesired features by still more intelligence reflection, and still more appropriate design and ’rational coordination’ of our undertakings. This leads one to be favorably disposed to the central economic planning and control that lie at the heart of socialism… And since they have been taught that constructivism and scientism are what science and the use of reason are all about, they find it hard to believe that there can exist any useful knowledge that did not originate in deliberate experimentation, or to accept the validity of any tradition apart from their own tradition of reason. Thus [they say]: ‘Tradition is almost by definition reprehensible, something to be mocked and deplored’.
