Deleuze rejects this view as papering over the metaphysical flux, instead claiming that genuine thinking is a violent confrontation with reality, an involuntary rupture of established categories. Truth changes what we think; it alters what we think is possible. By setting aside the assumption that thinking has a natural ability to recognize the truth, Deleuze says, we attain a “thought without image”, thought always determined by problems rather than solving them. “All this, however, presupposes codes or axioms which do not result by chance, but which do not have an intrinsic rationality either.”
