Wagner, a man of staggering genius, an artist of incredible magnitude, stood for much more than has been set down here. The conflict in the Ring operas often revolves around the theme of greed for gold, which the composer equated with the “tragedy of modern capitalism,” and which he saw, with horror, wiping out the old virtues which had come down from an earlier day. Despite all his pagan heroes he did not entirely despair of Christianity, as Nietzsche did. And he had great compassion for the erring, warring human race. But Hitler was not entirely wrong in saying that to understand Nazism one must first know Wagner.
Wagner had known, and been influenced by, first Schopenhauer and then Nietzsche, though the latter quarreled with him because he thought his operas, especially Parsifal, showed too much Christian renunciation.
