“I am not persuaded that Hayek got the substantive connections entirely right. He was too captivated by the enabling effects of the market system on human freedoms and tended to downplay - though he never fully ignored - the lack of freedom for some that may result from a complete reliance on the market system, with its exclusions and imperfections, and the social effects of big disparities in the ownership of assets. But it would be hard to deny Hayek's immense contribution to our understanding of the importance of judging institutions by the criterion of freedom.”
