Thank you all for your comments and suggestions. I appreciate them very much! I just re-read the rules for the armchair mailing list, and I hope this is not too methodological or whatever. Sorry about that!
I actually have read Mirowski's "More Heat Than Light" and found it quite informative. Interestingly, Richard Feynman, of all people, blew Mirowski's arguments out of the water (ex ante) with an almost throw-away line in his Physics Lectures. He asked himself why was math an appropriate tool for studying physical models. His answer was merely that math is a pre-packaged, internally consistent logic that physicists can apply to the aformentioned models. Hmm. By extension, that reasoning seemed to apply to economics quite well. It seemed to me that Mirowski's thesis was that math, specifically the math used in neo-classical economics, is an inappropriate tool for economic study because economics lacks a conservation rule analogous to the conservation of energy in Newtonian physics. However, if preferences are constant over time, then the conservation rule should be satisfied, right? I think that is my weakest link. I hope that last paragraph hasn't made me to appear a bonehead answering his own questions. (I'm boneheaded enough without doing that.) I guess what I was origially wondering was not "Is math appropriate?" But rather, given that math is appropriate, are the assumptions about rationality, preferences, convexity, continuity, inter alia, as well as some of the more ad hoc assumptions of many macro models as reasonable as the assumtions made in the king of all sciences? Obviously, I'm not really sure how to phrase the question in the most clear manner. I apologize for that. If this question is inappropriate for this forum, please let me know.
