Interlude II: [Contemporaneous Developments in Other Sciences]

From time to time, we shall look up from our work in order to view a piece of intellectual scenery. Slightly less perfunctorily, we shall, for every one of our periods, register some contemporaneous developments in other sciences (in our sense of the term) that were relevant or might, for one reason or another, be expected to have been relevant to the development of our own. What has to be said now about this aspect of our exposition is so preponderantly concerned with ‘philosophy’ that I might as well have entitled this chapter: Economics and Philosophy. The rest will be disposed of in the two paragraphs that follow.
