Title:
Friedrich_Hayek

Context:
Hayek wrote an essay, "Why I Am Not a Conservative" (included as an appendix to The Constitution of Liberty), in which he disparaged conservatism for its inability to adapt to changing human realities or to offer a positive political program, remarking, "Conservatism is only as good as what it conserves." Although he noted that modern day conservatism shares many opinions on economics with classical liberals, particularly a belief in the free market, he believed it's because conservatism wants to "stand still," whereas liberalism embraces the free market because it "wants to go somewhere." Hayek identified himself as a classical liberal, but noted that in the United States it had become almost impossible to use "liberal" in its original definition, and the term "libertarian" has been used instead. In this text, Hayek also opposed conservatism for "its hostility to internationalism and its proneness to a strident nationalism" and its frequent association with imperialism.
