 Other scholars have emphasized Nietzsche’s speculations that biological and physical phenomena could be explained by a postulated system of interacting power centers (Abel 1984; Müller-Lauter 1999a; Moore 2002; Gemes 2013). Abel (1984) offers a particularly systematic and carefully argued version of the approach, which highlights important resonances between Nietzsche’s ideas and elements of Leibniz’s dynamical physics and metaphysics, whereas Moore (2002) pursues a fascinating line of connections between Nietzsche’s thoughts about power and certain physiological ideas advanced by Wilhelm Roux (1881). Moore’s reading emphasizes the biologized rhetoric Nietzsche often uses in his talk about power (together with its connections to health and sickness, degeneration, etc.) as part of a case that the will to power idea locates Nietzsche’s philosophy within a wider intellectual trend toward “biologism” prevalent at the end of the nineteenth century.
