We thus leave behind the assemblages to enter the age of the Machine, the immense mechanosphere, the plane of cosmicization of forces to be harnessed. Varese's procedure, at the dawn of this age, is exemplary: a musical machine of consistency, a sound machine (not a machine for reproducing sounds), which molecularizes and atomizes, ionizes sound matter, and harnesses a cosmic energy. If this machine must have an assemblage, it is the synthesizer. By assembling modules, source elements, and elements for treating sound (oscillators, generators, and transformers), by arranging microintervals, the synthesizer makes audible the sound process itself, the production of that process, and puts us in contact with still other elements beyond sound matter. It unites disparate elements in the material, and transposes the parameters from one formula to another. The synthesizer, with its operation of consistency, has taken the place of the ground in a priori synthetic judgment: its synthesis is of the molecular and the cosmic, material and force, not form and matter, Grund and territory. Philosophy is no longer synthetic judgment; it is like a thought synthesizer functioning to make thought travel, make it mobile, make it a force of the Cosmos (in the same way as one makes sound travel).
This synthesis of disparate elements is not without ambiguity. It has the same ambiguity, perhaps, as the modern valorization of children's drawings, texts by the mad, and concerts of noise. Sometimes one overdoes it, puts too much in, works with a jumble of lines and sounds; then instead of producing a cosmic machine capable of "rendering sonorous," one lapses back to a machine of reproduction that ends up reproducing nothing but a scribble effacing all lines, a scramble effacing all sounds. The claim is that one is opening music to all events, all irruptions, but one ends up reproducing a scrambling that prevents any event from happening. All one has left is a resonance chamber well on the way to forming a black hole. A material that is too rich remains too "territorialized": on noise sources, on the nature of the objects ... (this even applies to Cage's prepared piano). One makes an aggregate fuzzy, instead of defining the fuzzy aggregate by the operations of consistency or consolidation pertaining to it.
