Sensation (n.) in the pure sense of a dotlike impact on the mind corresponds to nothing we ever experience: even a hen or an ape perceives relations, not isolated hits.
Sensation (n.) as traditionally defined is not the first thing in experience but the last: a late product of thinking about objects, the furthest from its source and so the least clear.
Sensation (n.) is the last effect of knowledge, not its first step — an understandable illusion that makes us put at the beginning what science arrives at in the end.
Sensation (n.) is literally a form of communion: like the sacrament, the sensible is a way of being in the world, offered from some point in space and taken up by a body prepared to receive it.
Sensation (n.) is intentional but blind: what it aims at is recognized only through the body's familiarity, entering into sympathy with a quality and finding in it its momentary law.
Sensation (n.) is a birth and a death: each one is the first, last and only of its kind, and its subject begins and ends with it.
