There's that fantastic passage in FM which I think supports this. Again, very powerful precisely because of the separation of regimes of thought, and what that separation declines to say.
I still find the ideas incredibly powerful. Specifically his critique of serialism and the new system of structures (vertical, horizontal, in and out of time) that follow from that critique. If it was a merely technical innovation, or a nitpicking argument with dodecaphony it wouldn't be such a big deal - but you don't need to read much of his writing to realise that it followed directly from a desire to compose music adequate to the task of expressing and considering our relationship to nature. I don't know another musician whose thought is so rigorously ambitious.Everyone has observed the sonic phenomena of a political crowd of dozens or hundreds of thousands of people. The human river shouts a slogan in a uniform rhythm. Then another slogan springs from the head of the demonstration; it spreads towards the tail, replacing the first. A wave of transition thus passes from the head to the tail. The clamor fills the city, and the inhibiting force of voice and rhythm reaches a climax. It is an event of great power and beauty in its ferocity Then the impact between the demonstrators and the enemy occurs. The perfect rhythm of the last slogan breaks up in a huge cluster of chaotic shouts , which also spreads to the tail. Imagine, in addition, the reports of dozens of machine guns and the whistle of bullets adding their punctuations to this total disorder. The crowd is then rapidly dispersed, and after sonic and visual hell follows a detonating calm, full of despair, dust and death. The statistical laws of these events, separated from their political or moral context, are the same as those of cicadas or rain.
