Note D — Chapter IV

The monads of Leibniz could justly be called minds, because they had a dramatic destiny, and the most complex experience imaginable was the state of but one monad, not an aggregate view or effect of a multitude in fusion. But the recent improvements on that system take the latter turn. Mind-stuff, or the material of mind, is supposed to be contained in large quantities within any known feeling. Mind-stuff, we are given to understand, is diffused in a medium corresponding to apparent space (what else would a real space be?); it forms quantitative aggregates, its transformations or aggregations are mechanically governed, it endures when personal consciousness perishes, it is the substance of bodies and, when duly organised, the potentiality of thought. One might go far for a better description of matter. That any material must be material might have been taken for an axiom; but our idealists, in their eagerness to show that Gefuehl ist Alles, have thought to do honour to feeling by forgetting that it is an expression and wishing to make it a stuff.

There is a further circumstance showing that mind-stuff is but a bashful name for matter. Mind-stuff, like matter, can be only an element in any actual being. To make a thing or a thought out of mind-stuff you have to rely on the system into which that material has fallen; the substantive ingredients, from which an actual being borrows its intensive quality, do not contain its individuating form. This form depends on ideal relations subsisting between the ingredients, relations which are not feelings but can be rendered only by propositions.
