The heuristic value of the tentative theory of sympathy set forth in the preceding chapters will hopefully be seen in the research it has encouraged. For now, however, a brief review of the theory may be helpful. It must be emphasized again that sympathy is a complicated phenomenon, and that this tentative theory of sympathy is only a first approximation of a fuller theory of sympathy, including specific hypotheses for testing. In this chapter I will briefly review the theory, indicate some paradoxes inherent in it, and try to put both into perspective.
