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.
