Nietzsche was surprisingly neglected by most English-language moral philosophers until recently. This volume capitalizes on a growth of interest in Nietzsche's work on morality from two sides - from scholars of the history of philosophy and from contributors to current debates on ethical theory. In eleven new essays, leading philosophers aim both to advance philosophical understanding of Nietzsche's ethical views - his normative and meta-ethics, his moral psychology, his views on free will and the nature of the self - and to make Nietzsche a live participant in contemporary debates in ethics and cognate fields.
