Nietzsche's ethical thought: Reassurance and affirmatio

My dissertation concerns Nietzsche's ethical thought. At the center of Nietzsche's philosophical ethics was the attempt to provide some reassurance about the status of norms and values. On his diagnosis, intensifying self-scrutiny with regard to ethical commitments has led to a contemporary situation in which no way of life seems particularly authoritative or worthwhile. Nietzsche therefore sought some means to extend and satisfy critical scrutiny, so as to find norms and values that sustain their "force.";In the first chapter I trace the early development of Nietzsche's project, especially how his philosophical concerns about reassurance and the authority of norms arose out of his philological interest in the meaning of cultural phenomena. I argue that Nietzsche's philosophical concerns were "existential" in character, and that he eventually settled on a "rationalist" approach to addressing them.;The second chapter concerns Nietzsche's argument for the inadequacy of appeals to truth or nature to resolve questions of an existential scope. Nietzsche argued that appeals to truth depend on prior normative commitments and thus cannot be decisive against critical doubt.;Chapter III concerns the critical aspect of Nietzsche's project, namely genealogy. Genealogy recounts the history of ethical "ideals" in terms of their purposiveness, and assesses them in terms of their success or failure. Nietzsche argued that even ethical ideals are in some way functional, and one can thus assess whether or not they 'work.' This provides the critical leverage with which Nietzsche scrutinizes and finds fault with defective ideals: his account of their necessary failure.;The final chapter concerns Nietzsche's constructive, or "affirmative" project. Nietzsche argued that an assessment of norms and values in terms of their ability to sustain "affirmation" is critically adequate. That is, for a norm or value to survive scrutiny, it has to serve to guide or structure a life that inspires an allegiance to that life that Nietzsche described as "erotic" in character. Nietzsche argued that some such commitment is necessary for one to be able to give meaning to one's life, and that this is a precondition for any determination of freedom.
