Introduction of Local Diversity in Sense Data

We have just studied two primary types of geometries of sense data. Both have as elementary connections the same relations: succession and perfect global resemblance. But they interlace differently, because the resemblance of two terms marks in one case the presence of the observer in the same auditory place, and in the other case, the same propulsion of his organs. If experience is restricted to these two relations, the first case has illustrated geometry in the data of any external sense, and the second, in the data of the internal sense of movement and attitude.
