My reply to Peter is that, yes, it is true, and Hayek says, that, 
"There is no single man to whom I owe more intellectually", and it is 
also true, at the same time, that, that once we get past the fact that 
Hayeked owed his problems to their casting by Mises, and their inadequete 
treatment by Mises, what we find is that Hayek is more clearly influenced 
in the _answers_ he provided by Menger, Wieser, and Wicksell, than he 
is by Mises -- and in fact, although Mises gave Hayek the problems in a 
form that gave Hayek a task to complete, these problems are found earlier 
in less pointed versions in the workds of Menger, Wieser, Bohm-Bawerk, 
and Wicksell (i.e. the knowledge problem, and the problem of making sense 
of the role of equilibrium constructions in monetary theory and trade 
cycle theory, and the problem of socialist calculation -- all problems  
already found in Menger, Wieser, Bohm-Bawerk, and Wicksell).  Mises cast 
problems from Menger,Wieser, Bohm-Bawerk, and Wicksell in a form that 
gave Hayek work to do, solution to find that were not adequately provided 
by Mises, just as they were not adequately provided by Menger, Wieser, 
Bohm-Bawerk, and Wicksell.  But Hayek's solution came out of the work of 
Menger, Wieser, and Wicksell, much more that it did Mises, or Mises teacher 
Bohm-Bawerk.  At least that is my judgment -- again I think there are no 
cut and dried 'right answers' here.  Peter could easily provide a more  
detailed demostration which changes my mind.  But even Hayek's remarks when 
delivering a lecutre in honor of Ludwig von Mises do not seem decisive in 
establishing the issue one way or the other.  There is too much evidence 
on the other side, as far as I can tell looking at all of the material that 
I am familiar with.

didn't make that clear in the above.]
