THE HISTORY OF IDEAS can be approached in two ways. The first treats its materials like fossils, to be unearthed as clues to the past. Occasionally these exciting discoveries shed light on current concerns, but that is by no means a necessary reward. There is instead the thrill of the search, of tracking down a neglected work, of finding an outlook that is intrisically interesting, if not always fresh or vital. The other approach seeks out pioneers who have contributed to a continuum of intellectual progress. The aim is to establish theoretical pedigrees, to show the sources from which later refinements derive their inspiration. In some instances the stature of the innovator overshadows that of the followers, and a renascence or redirection of energies is required. The ethical theory of the Finnish philosopher Westermarck (18621939) repays study from either standpoint: his writings are of interest in their historical context and of value to contemporary philosophy. Yet subsequent commentators have seldom recognized either of these merits in Westermarck ' s work. This is not entirely true of Nordic writers, who have contributed scattered articles on his life and thought, 1 but otherwise Westermarck has suffered a shabby treatment in the four decades since his death. When he is remembered at all, it is usually by critics who attribute to him an untenable subjectivism, a paradigm of what must be avoided in analyzing ethical discourse. Most of Westermarck 's interpreters have been guilty of judging him through eyeglasse. ~, or blinders----of contemporary philosophical method or of letting their description be colored by its role in philosophical disputation. The result is distortion of the aims and orientation, as well as the substance, of Westermarck 's moral philosophy, and misunderstanding can lead to easy dismissal.
