ABSTRACT
Cambridge versus Cambridge controversy, or the reswitching and capital reversing debate. When I started to work on it, my hypothesis was that the sense of confusion was a direct consequence of the highly abstract level on which the discussion took place, which is shown by the idealizing character of themodels used. I also thought that the confusionwas due to a failure to distinguish different types of idealizations. It turned out that idealizations are indeed of prime importance as factors that influence the way in which the debate evolved. But in the attempt to give more definite content to the original hypothesis, I discovered that the explanation of the confusion was even more complicated than I had thought.
