 An alternative view to monism, motivated by the variety of species concepts, is pluralism, which holds that the different accounts of species in systematics reflect equally legitimate ways of carving up nature subject to our pragmatic and theoretical interests. However, these systems do carve nature in genuinely natural ways. The species and higher taxa that they delineate reflect real features of the world from the point of view of different theoretical interests. Pluralism (Kitcher 1984; Dupré 1993; Ereshefsky 1992) is the weakest form of realism about kinds in the philosophy of biology.
