The Mask of Enlightenment is the most detailed textual and thematic study of Nietzsche's most important but least understood works: Thus Spake Zarathustra. In this book Nietzsche was laying the groundwork for a fundamental philosophical and political revolution on a global scale. One of the difficulties that the text poses is Nietzsche's prophetic style; Stanley Rosen unweaves the complex threads that form the rhetorical voices of the work, and so explains the style in an accessible manner. He rejects recent sceptical, deconstructionist interpretations of Nietzsche, and reveals a coherence underlying the multiple and apparently incompatible intentions embedded in the text. Nietzsche is a figure whose influence on contemporary thought in the humanities and social sciences continues to be enormous. This book is sure to become the definitive study of Zarathustra, and will have a broad appeal to philosophers and students of modern philosophy, intellectual historians, political scientists, and literary theorists.
