In this brief yet substantial volume, first published in 1914, noted philosopher Paul Carus surveys Nietzsche's views on the overman, ego-sovereignty, the principle of valuation, individualism, and more. Not just a book on Nietzsche's philosophy, it contains biographical information based on the recollections of Paul Deussen, Nietzsche's closest friend, and chapters on his predecessor and disciples. This treatise serves as both an introduction to and further reflection on one of the most controversial philosophers of the 19th century. American philosopher and theologian PAUL CARUS (1852-1919) also wrote The Religion of Science (1893), The Gospel of Buddha (1894), and The History of the Devil (1900).
