It is maintained, not without an appearance of reason, that there is no sensation without extensity[1] or without a feeling 'of volume.'[2] English idealism sought to reserve to tactile perception a monopoly of the extended, the other senses dealing with space only in so far as they remind us of the data of touch. A more attentive psychology reveals to us, on the contrary, and no doubt will hereafter reveal still more clearly, the need of regarding all sensations as primarily extensive, their extensity fading and disappearing before the higher intensity and usefulness of tactile, and also, no doubt, of visual, extensity.

ConcreteWe invert reality when we regard rest as logically anterior to motion, space as the necessary antecedent to movements. extensity, that is to say the diversity of sensible qualities, is not within space; rather is it space that we thrust into extensity.

But it must not be forgotten that the point of view of the Critique is other than
