Nihilism, Nietzsche and the Doppelganger Problem Was Nietzsche a nihilist? Yes, because, like J. L. Mackie, he was an error-theorist about morality, including the elitist morality to which he himself subscribed. But he was variously a diagnostician, an opponent and a survivor of certain other kinds of nihilism. Schacht argues that Nietzsche cannot have been an error theorist, since meta-ethical nihilism is inconsistent with the moral commitment that Nietzsche displayed. Schacht’s exegetical argument parallels the substantive argument (advocated in (...) recent years by Wright and Blackburn) that Mackie’s error theory can’t be true because if it were, we would have to give up morality or give up moralizing. I answer this argument with a little bit of help from Nietzsche. I then pose a problem, the Doppelganger Problem, for the meta-ethical nihilism that I attribute to Mackie and Nietzsche. (If A is a moral proposition then not-A is a moral proposition: hence not all moral propositions can be false.) I solve the problem by reformulating the error theory and also deal with a variant of the problem, the Reinforced Doppelganger, glancing at a famous paper of Ronald Dworkin’s. Thus, whatever its demerits, the error theory, is not self-refuting, nor does it require us to give up morality. (shrink)

In this paper, I argue that Nietzsche’s published works contain a substantial, although implicit, argument for the will to power as ontology—a critical and descriptive, rather than positive and explanatory, theory of reality. Further, I suggest this ontology is entirely consistent with a naturalist methodology. The will to power ontology follows directly from Nietzsche’s naturalist rejection of three metaphysical presuppositions: substance, efficient causality, and final causality. I show that a number of interpretations, including those of Clark, Schacht, Reginster, and (...) Richardson, are inconsistent with Nietzsche’s naturalism, because they presuppose efficient or final causality. In contrast, I argue that the will to power is not an explanatory theory, but a description of the basic, necessary character of reality, designed to critically reveal and minimize metaphysical presuppositions—to reject false explanations of reality and human behavior. It avoids substance-metaphysics by describing reality as will, a causal process without discrete efficient causes or agents. It eliminates efficient causality by describing events as maximal manifestations of power, rather than as agent-actualized potentialities. Finally, it opposes teleology by describing life as tending toward the activity of resistance as such, rather than toward explanatory end-states, such as the accumulation of power or overcoming of resistances.

Leiter’s book serves, in one sense, as a summation of two decades of scholarship during which American and British philosophers have sought to reframe Nietzsche’s philosophy in terms of traditional analytic concerns in ethics, epistemology, and metaphysics and thereby to challenge (or simply ignore) dominant Continental readings. Richard Schacht’s comprehensive Nietzsche (Routledge 1983) marked the beginning of this effort. The work of Maudemarie Clark, with whom Leiter has collabroated on other projects, represents another landmark.
