“Stemming from the Germanic philosophical heritage, Hayek was likely to place more emphasis on the act of knowing than on objects themselves. Hayek ultimately followed Kant in his ontological conception of reality—he thought that mind impresses order on existence.”

“His epistemology began from a phenomenalist base. The philosopher and physicist Ernst Mach was very important in Hayek’s development and to the atmosphere at the University of Vienna when Hayek was a student there.”

Alan O. Ebenstein (1959) American political scientist, educator and author

“Keynes ultimately placed his hopes for good government in exceptional men. The focus in Hayek’s work was rules.”

Alan O. Ebenstein (1959) American political scientist, educator and author

“Hayek’s practical political thought was flawed not where he postulated too small a role for government, but where he sanctioned too great a role. In his late work, Hayek the classical liberal became Hayek the libertarian.”

Alan O. Ebenstein (1959) American political scientist, educator and author

“Hayek expressed more fully and deeply than Mises the epistemological argument for free market order. The crucial issue for Hayek became not that without prices individuals cannot calculate (though he thought this to be the case), but that the division of knowledge renders centralized control of an economy or society impossible.”

Alan O. Ebenstein (1959) American political scientist, educator and author

“Hayek truly did get Popper his position at the London School of Economics. “I am personally anxious to get Dr. Popper to this School,” Hayek wrote Gombrich as early as 1943. Given the later prominence that Popper achieved for the school, this was one of Hayek’s most significant contributions to its reputation, as well as the decisive career move in Popper’s life.
Hayek also genuinely influenced Popper’s political philosophy. While Popper always remained to Hayek’s left, he started out much further to Hayek’s left than he wound up, and this movement was in no small part the result of Hayek’s influence. Popper was a charter member of the Mont Pelerin Society. He suggested, however, that socialists be brought into it. Hayek wrote Popper several deeply personal letters in connection with his divorce. It is likely that their personal relationship was more important to and valued by Hayek than Popper, though Popper valued highly Hayek’s friendship.”

“Hayek’s work in philosophy can be considered from another perspective than its methodology. When Hayek wrote that his philosophical studies should precede his political studies, he meant that in order to explain the sort of political system he favored, it was necessary to have greater understanding of the transmission and communication of information and knowledge. This is why he wished to travel to Italy and Greece. He thought that he might understand nonverbal knowledge better in doing so and might better understand the role of institutions in transmitting knowledge and information.”

Alan O. Ebenstein (1959) American political scientist, educator and author

“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.”

Bruce Caldwell (economist) (1952) economic historian

“One of the paradoxes of Hayek is that he wrote better than he thought. That is, his writing is often more suggestive and stimulating than the thought that underlaid it. While his writing is, stylistically, difficult, it is also exceptionally profound, and its value lies in its profundity.”

Alan O. Ebenstein (1959) American political scientist, educator and author

“Hayek’s essential political philosophy was that liberty is the supremacy of law. To some, this may appear a paradoxical conception of liberty, for liberty is too often considered to be the absence of law. This, however, was the exact opposite of Hayek’s view. He thought that liberty is not possible without law. Right law is liberty.”
