Note 119 — Chapter II · THE PROBLEM OF MATTER

This definition of the physical order approximates very closely to that adopted by Prof. Münsterberg in his Grundzüge der Psychologie, vol. i. pp. 65-77. Prof. Münsterberg defines a physical fact as one which is directly accessible to the perception of a plurality of sentient individuals, as opposed to the psychical fact which can be directly experienced only by one individual. It must be remembered, of course, that my body as directly experienced in “common sensation” and “emotional mood” belongs to the psychical order. It is only my body as perceptible by other men that is a member of the physical order.
