 Rand paid tribute to Aristotle, whom she considered the greatest of all philosophers, in the titles she gave to the three Parts of Atlas Shrugged (Non-Contradiction, Either-Or, A is A) and to one of the chapters (The Immovable Movers). While she differed sharply from Nietzsche on many issues, including rationality, free will, and individual rights, his influence is evident in her provocative, often aphoristic, point-counterpoint writing style, as well as in her “transvaluation” of traditional values and her powerful affirmation of life and joy and the spirit of youth. In the Introduction to the 25th Anniversary edition of The Fountainhead, she stated that the novel’s sense of life is best conveyed by a quotation from Nietzsche’s Beyond Good and Evil: “The noble soul has reverence for itself”. (For The Fountainhead’s partly sympathetic and partly critical engagement with Nietzsche’s ideas, see Hunt 2006.)
