Never will man penetrate deeper into error than when he is continuing on a road which has led him to great success

Friedrich August von Hayek

If I am not mistaken, psychology, psychiatry and some branches of sociology, not to speak about the so-called philosophy of history, are even more affected by what I have called the scientistic prejudice, and by specious claims of what science can achieve.
FRIEDRICH AUGUST VON HAYEK

Philosophy Prejudice Psychology
To create conditions in which competition will be as effective as possible, to prevent fraud and deception, to break up monopolies- these tasks provide a wide and unquestioned field for state activity.
FRIEDRICH AUGUST VON HAYEK

Competition Deception Tasks
It seems to me that socialists today can preserve their position in academic economics merely by the pretense that the differences are entirely moral questions about which science cannot decide.
FRIEDRICH AUGUST VON HAYEK

Differences Moral Today

FRIEDRICH AUGUST VON HAYEK

[T]hose who are willing to surrender their freedom for security have always demanded that if they give up their full freedom it should also be taken from those not prepared to do so.
FRIEDRICH AUGUST VON HAYEK

Giving Surrender Taken Up
It is perhaps the most characteristic feature of the intellectual that he judges new ideas not by their specific merits but by the readiness with which they fit into his general conceptions, into the picture of the world which he regards as modern or advanced.
FRIEDRICH AUGUST VON HAYEK

Ideas Judging Philosophy
Wherever liberty as we understand it has been destroyed, this has almost always been done in the name of some new freedom promised to the people

The mind cannot foresee its own advance.
FRIEDRICH AUGUST VON HAYEK

Advance Foresee Mind Own
It is rather a problem of how to secure the best use of resources known to any of the members of society, for ends whose relative importance only those individuals know.
FRIEDRICH AUGUST VON HAYEK

Individual Problem Use
The chief evil is unlimited government, and nobody is qualified to wield unlimited power.
FRIEDRICH AUGUST VON HAYEK

Evil Government Unlimited
It used to be the boast of free men that, so long as they kept within the bounds of the known law, there was no need to ask anybody’s permission or to obey anybody’s orders. It is doubtful whether any of us can make this claim today.

Capitalism created the possibility of employment.
FRIEDRICH AUGUST VON HAYEK

Capitalism Employment Possibility
There may be few instances in which the superstition that only measurable magnitudes can be important has done positive harm in the economic field: but the present inflation and employment problems are a very serious one.
