Critics argue that Hayek mixed a number of ethical and political philosophies in constructing his system, positions that do not necessarily cohere on… - Bruce Caldwell

Hayek is a puzzle. Certainly he started out as one for me, now some twenty-odd years ago.

It seems evident from his unpublished piece that his reading of the Mill-Taylor letters gave Hayek a bit of a shock. He knew, of course, from the Autobiography that Mill had an elevated opinion of Mrs. Taylor. The letters seem to have convinced Hayek that she dominated him. Hayek would doubtless have seen this as a weakness, and he might well have lost some respect for Mill as a result. It may also have provided a convenient explanation for Hayek for why a great mind like Mill might nonetheless “desert” the liberal camp. (Hayek’s hope to lead others to the same conclusion might have helped motivate him to write the book on the correspondence between Mill and Taylor.) Given what has sometimes been said about the dominating personality of Hayek’s second wife, one wonders whether Hayek would later in his life have felt even more commonalities with Mill.

Some may wish to argue that Hayek was simply born with a sort of natural pessimism or cynicism, and that this generated his long standing belief in the inherent limitations that humans face when they try to intervene in social phenomena. Perhaps. But it is also possible that this view was the product of his having come of age during the final collapse of an already broken-down empire, of having experienced the multiple forms of disaster that surrounded postwar Vienna and enveloped interwar central Europe, and of having witnessed the failures of various high-minded social experiments to achieve anything like what their exponents had promised. In bearing witness to so much tragedy Hayek was again very much a part of the larger Austrian tradition. His famed ‘‘epistemic pessimism’’ may well have been another result of that larger experience.
