If philosophy consists of conceptual analysis, is it thereby debarred from being a science? This article argues that it is not and that philosophy so conceived is a science. The argument takes the form of careful attention to the meaning of “science,” “experiment,” “empirical,” and related words. Philosophy is a formal science. This does not mean it is not part of the humanities. The role of observation in other kinds of science is investigated. There is more methodological homogeneity in the (...) various sciences, including philosophy, than has been recognized, despite some clear differences. Seeing this helps restore philosophy to its rightful place in the academic firmament. (shrink)
