Arthur M. Diamond argues Hayek's problems arise when he goes beyond claims that can be evaluated within economic science. Diamond argued that: “The human mind, Hayek says, is not just limited in its ability to synthesize a vast array of concrete facts, it is also limited in its ability to give a deductively sound ground to ethics. Here is where the tension develops, for he also wants to give a reasoned moral defense of the free market. He is an intellectual skeptic who wants to give political philosophy a secure intellectual foundation. It is thus not too surprising that what results is confused and contradictory.” Question: What is Hayek trying to defend, according to Diamond?
