On the Genealogy of Morals is a book about interpretation and the history of ethics which raises profoundly disquieting issues about the violence of both. This is the most sustained of Nietzsche's later works and offers one of the fullest expressions of his characteristic concerns. The introduction places his ideas within the cultural context of his own time and stresses the relevance of his work for a contemporary audience. Friedrich Nietzsche is one of the most influential thinkers of the past 150 years and On the Genealogy of Morals is his most important work on ethics and politics. A polemical contribution to moral and political theory, it offers a critique of moral values and traces the historical evolution of concepts such as guilt, conscience, responsibility, law and justice.
