Daybreak was Nietzsche's fourth book, written in his so-called 'positivist' period and before the development of this doctrines of perspectivism and the superman. Employing the aphoristic style that allowed his thought its flexibility and directness, the writing is characteristically invigorating, acute and paradoxial. It displays his clear confidence in the power of reason, and Nietzsche's foremost concern in this book is to unmask the fictions and delusions of European values above all of European morality. The unblinking challenges and subtle diagnoses presented here of its ingrained presuppositions and beliefs inspired and anticipated the most adventurous thought of this century, from Freud to Foucault. They are, as Nietzsche says, the researches of 'an underground man'. This entirely new translation is the only modern one available. With the introduction by Michael Tanner, it will enable this masterpiece to be fully and property appreciated in the English speaking world.
