Book excerpt: This wide-ranging and inspiring volume of essays explores Nietzsche's philosophy of the free spirit. Nietzsche begins to articulate his philosophy of the free spirit in 1878 and it results in his most congenial books, including Human, all too Human, Dawn (or Daybreak), and The Gay Science. It is one of the most neglected aspects of Nietzsche's corpus, yet crucially important to an understanding of his work. Written by leading Nietzsche scholars from Europe and North America, the essays in this book explore topics such as: the kind of freedom practiced by the free spirit; the free spirit's relation to truth; the play between laughter and seriousness in the free spirit period texts; integrity and the free spirit; health and the free spirit; the free spirit and cosmopolitanism; and the figure of the free spirit in Nietzsche's later writings. This book fills a significant gap in the available literature and will set the agenda for future research in Nietzsche Studies.
