Nietzsche controversially valorizes struggle and war as necessary ingredients of human flourishing. In this book, James S. Pearson reconstructs Nietzsche's rationale for placing such high value on relations of conflict. In doing so, Pearson reveals how Nietzsche's celebration of social discord is interwoven with his understanding of nature as universal struggle. This study thus draws together Nietzsche's writings on politics, culture, metaphysics, biology and human psychology. It also overcomes an entrenched dispute in the critical literature. Until now, commentators have tended to interpret Nietzsche either as an advocate of radical aristocratic violence or, by contrast, a defender of moderate democratic contest. This book navigates a path between these two opposed readings and shows how Nietzsche is able to endorse both violent strife and restrained competition without contradicting himself.
