From what little I know, it seems that the best place to start would be to read Bertrand Russell's accounts of "egocentricity," to which he alludes in his delightfully amusing refutation of Strawson in Russell's article "Mr. Strawson on Referring". In that article, Russell cites his views of egocentricity presented in his books "An Inquiry into Meaning and Truth," 1940, Ch. VII, and in "Human Knowledge: Its Scope and Limits," 1948, Part II, Ch. IV.
