Dear Marschak

I hoped that as I wrote this out, [1] means of giving empirical check to the theory could suggest themselves. I fear that this has not been the case. The relations which can be empirically measured even by the most refined methods are so crude by comparison with a theory of this sort, and that despite the fact that I have presented it in an extremely simple form, and by reasoning in which there is only one step. But I confess that I havent really given my mind on the verification aspect.

If you can do so, without unduly encumbering your time and exhausting your energy, I should be very grateful if you could read through this and consider it from the point of view of verification. We might then be in a position to talk over possibilities. But dont bother with it if you are already over-worked. In this case you might return it to me at once, since I am short of copies, and I shall let you have it back later.

I hope health is good and that you have not been carried by those administrative problems, which, I feel sure, will ultimately be solved in a way advantageous to yourself. I have just been reading the autobiography of Benvenuto Cellini. [2] You might look at it as a warning! I think you have a touch of the Cellini in your composition!

Yours sincerely

Roy Harrod
