For all their differences, the transcendental philosophies of Kant and Deleuze converge on the need for a principle of the determination of what is given to sensation. This principle, the point of contact between the determined and undetermined, would be a ground of sensation and therefore of all outer experience. For both Kant and Deleuze, this ground can be localised in intensity as the degree of force of the real. But it is Deleuze's unique combination to show that depth, the (...) matrix of intensity, serves as a ground only insofar as it is also an ungrounding. (shrink)
