Nietzsche found in classical Athenian tragedy an art form that transcended the pessimism and nihilism of a fundamentally meaningless world. The Greek spectators, by looking into the abyss of human suffering and affirming it, passionately and joyously affirmed the meaning of their own existence. They knew themselves to be infinitely more than petty individuals, finding self-affirmation not in another life, not in a world to come, but in the terror and ecstasy alike celebrated in the performance of tragedies.
The Case of Wagner is a critique of Richard Wagner and the announcement of Nietzsche's rupture with the German artist, who had involved himself too much, in Nietzsche's eyes, in the Völkisch movement and antisemitism. His music is no longer represented as a possible "philosophical affect," and Wagner is ironically compared to Georges Bizet. However, Nietzsche presents Wagner as only a particular symptom of a broader "disease" that is affecting Europe: that is, nihilism. The book shows Nietzsche as a capable music-critic, and provides the setting for some of his further reflections on the nature of art and its relationship to the future health of humanity.
This work is in sharp contrast with the second part of Nietzsche's The Birth of Tragedy, wherein he praised Wagner as fulfilling a need in music to go beyond the analytic and dispassionate understanding of music. Nietzsche also praised Wagner effusively in his essay "Wagner at Bayreuth" (part of the Untimely Meditations), but his disillusion with Wagner the composer and the man was first seen in his 1878 work Human, All Too Human. One of the last works that Nietzsche wrote returned to the critical theme of The Case of Wagner. In Nietzsche contra Wagner, Nietzsche pulled together excerpts from his works to show that he consistently had the same thoughts about music, only that he had misapplied them to Wagner in the earliest works.
