Book excerpt: Nietzsche's Revaluation of Values is an assessment of Nietzsche's challenging plan to revalue all values, including knowledge, morality, religion, art, and the state. E. E. Sleinis analyzes the success of Nietzsche's enterprise as well as its inadequacies; among the positive contributions he singles out Nietzsche's theory of value, his conception of higher-order values, and his conception of the maximally affirmative attitude as creations of enduring importance.
