George Bernard Shaw, “The Perfect Wagnerite, Commentary on the Ring”

All the loftiest spirits of that time were burning to raise Man up, to give him self-respect, to shake him out of his habit of grovelling before the ideals created by his own imagination, of attributing the good that sprang from the ceaseless energy of the life within himself to some superior power in the clouds and of making a fetish of self-sacrifice to justify his own cowardice.

Why he should not become an honest giant again and clear out of his cavern, leaving the gold and the ring and the rest of it for anyone fool enough to take them at such a price, is the first question that would occur to anyone except a civilized man, who would be too accustomed to that sort of mania to be at all surprised at it.

The prelude to Tristan and Isolde is such an astonishingly intense and faithful translation into music of the emotions which accompany the union of a pair of lovers that it is questionable whether the great popularity of this piece at our orchestral concerts really means that our audiences are entirely catholic in their respect for life in all its beneficently creative functions, or whether they simply enjoy the music without understanding it.
