摘要

Many astronomers seem to believe that we have discovered that Pluto is not a planet. I contest this assessment. Recent discoveries of trans-Neptunian Pluto-sized objects do not militate for Pluto's expulsion from the planets unless we have prior reason for not simply counting these newly-discovered objects among the planets. I argue that this classificatory controversy which I compare to the controversy about the classification of the platypus illustrates how our classificatory practices are laden with normative commitments of a distinctive kind. I conclude with a discussion of the relevance of such "norm-ladenness" to other controversies in the metaphysics of classification, such as the monism/pluralism debate. (C) 2017 The Author.
