The conflict of ideas between Hayek and Keynes in the field of rules, laws, norms, morality, ethics, etc. is a deep one, rooted opposed systems of ideas. Hayek was aware of this gulf -- now and then quoting Keynes' discussion of how Keynes and his group were "immoralists", much of this view the effect of a Cambridge education, most especially the influence of G. E. Moore and his _Principia Ethica_. A scholar would have to tease out differences between Hayek's account of rules, laws, norms, morality and ethics, (etc.) and the sort of vision falling out of the Keynes & friends group reaction to Moore and his account of the world of rules and ethics. Whether or not Hayek took "pot shots" at Keynes is really of secondary interest to a historian of ideas. It goes without saying that the job of fully capturing Hayek's understanding of rules, laws, norms, morality and ethics has not as yet been very successfully done, and I know of no good accountcomparing Hayek's view to that of a reconstructed Keynesian view.
