There’s no doubt that Chicago was distinctive, and has been ever since. The real distinction was not making price theory the focal point of the graduate curriculum. That isn’t the real distinction at all. The fundamental distinction is treating economics as a serious subject versus treating it as a branch of mathematics, and treating it as a scientific subject as opposed to an aesthetic subject, if I might put it that .
