The synthesizer, with its operation of consistency, has taken the place of the ground in a priori synthetic judgement: its synthesis is of the molecular and the cosmic, material and force, not form and matter, Grund and territory. Philosophy is no longer synthetic judgement; it is like a thought synthesiser functioning to make thought travel, make it mobile, make it a force of the Cosmos (in the same way one makes sound travel).
