Benjamin B. Rubinstein There follows a slightly abridged version of Rubinstein's 1975 paper, Chapter 6 in his collected papers (Holt, 1997). All omissions are indicated by ellipses (…) except that footnotes and references have also been left out, to save space. Readers are encouraged to consult the book, Psychoanalysis and the Philosophy of Science, for the complete version. Its footnotes contain further, supplementary commentary. Anyone who is not familiar with Rubinstein's writing may be initially put off by its rather dry, economical style. The clinical examples here are few and not much elaborated; the author is evidently preoccupied with abstract, theoretical matters-not everyone's cup of tea. This brew is not so much refreshing as it is nutritious. It demands sustained attention; study rather than a quick read. It will reward repeated, close readings, however. They will acquaint you with the orderly, profound mind of a thinker who cuts no corners, indulges in no rhetorical sleight-of-hand, does not repeat himself or show off his erudition. Perhaps it is an acquired taste, but I find it refreshing as well as stimulating to listen to a psychoanalyst who says what he means directly, plainly, and clearly, and who wrote only when he had thought things through. It is only fair to add, however, that this is one of his most difficult papers, and that some show his delight in and skill in elucidating literary works.
