Hayek's forward to the 1952 printing by The University of Chicago Press,
which was also dedicated to "THE SOCIALISTS OF ALL PARTIES."

Hayek wrote: "The fact that this book was originally written with only the
British public in mind does not appear to have seriously affected its intelligibility
for the American reader. But there is one point of phraseology which I ought to
explain here to forestall any misunderstanding. I use throughout the term "liberal"
in the normal nineteenth century sense in which it is still current in Britain.
In current American usage it often means very nearly the opposite of this. It has
been part of the camouflage of leftish movements in this country, helped by the
muddleheadedness of many who really believe in liberty, that "liberal" has come
to mean the advocacy of almost every kind of government control. I am still
puzzled by those in the United States who truly believe in liberty should not only
have allowed the left to appropriate this almost indispensable term but should
even have assisted by beginning to use it themselves as a term of opprobrium.
This seems to be particularly regrettable because of the consequent tendency of many
true liberals to describe themselves as conservatives.
