Right or wrong, he resolved, or conceived that he had resolved, the perception of matter into its constituent elements, these being a mental operation on the one hand and a material existence on the other.

He accepted, as a thing of course, the notorious distinction between the perception of matter and matter itself; and, in doing so, he merely followed the example of all preceding psychologists.
These two points being established—first, that the theory of representationism necessarily arises out of an analysis of the perception of matter; and, secondly,
