Aesthetic feelings are distinguished from sensory feelings, now, by the fact that the former are related to the content of a presentation, the latter to the act itself. 21 Thus sensory feelings, but not aesthetic feelings, are directly sensitive to the quality and intensity of the act, and all sensations are, above a certain intensity, painful. Further, the sensory feeling disappears or is at least reduced to an almost unnoticeable intensity in the passage from sensation (perception) to a reproduced presentation in memory. .
