"Today a philosophy of music is possible only as a philosophy of new music."

"Music participates in what Clement Greenberg called the division of all art into kitsch and avant-garde, and kitsch — the dictatorship of profit over art — has long since subjugated the particular, socially reserved sphere of art. This is why reflections on the development of truth in aesthetic objectivity must be confined uniquely to the avant-garde, which is excluded from official culture. Today a philosophy of music is possible only as a philosophy of new music. What sustains is only what denounces official culture; the latter alone serves the promotion of that barbarism over which it waxes indignant. The cultured listeners almost seem to be the worst: those who promptly respond to Schoenberg's music with "I don't understand that" — a statement whose modesty rationalizes rage as connoisseurship."
