The book deals with numerous case studies of various artists, writers and thinkers (Oscar Wilde, Henrik Ibsen, Richard Wagner and Friedrich Nietzsche to name a few), but its basic premise remains that society and human beings themselves are degenerating, and this degeneration is both reflected in and influenced by art. Hannah Arendt, in her book The Origins of Totalitarianism, refers to late 19th Century French society as embracing unusual or exotic types or individuals, such as criminals, Gypsies and Turks, and certain others formerly not seen as socially acceptable, so Nordau's position is not novel or isolated as social criticism.
