 According to this account, Russell’s initial project of replacing inference with logical construction was to find for each pattern of sense data some logical construction that bears a pattern of isomorphic structural relations. That project was transformed, Demopoulos and Friedman argue, by replacing inference from the given in experience to the cause of that experience with an inference to the rather impoverished, structural, reality of the causes of those experiences. Russell’s matter project was interpreted in this way by others, and led, in 1928, to G.H. Newman’s apparently devastating objection. Newman (1928) pointed out that there is always a structure of arbitrarily “constructed” relations with any given structure if only the number of basic entities, in this case sense data, is large enough. According to Demopoulos and Friedman, Newman shows that there must be more to scientific theories than trivial statements to the effect that matter has some structural properties isomorphic to those of our sense data. The project of The Analysis of Matter does indeed face a serious difficulty with “Newman’s problem”, whether or not those difficulties arise for the earlier project of logical construction (see Linsky 2013).
