Our author is loud in his praises of Panpsychism, that phase of pantheism which regards all matter as saturated with a potential psyche. He speaks of the “catholicity, sublimity and beauty ... not to say the philosophy, and logic, and truthfulness of this creed of thought.” It is, however, clear that some of the authorities he cites in support of this view, more especially Clifford, Tyndall, and Ueberweg, represent a phase of thought which is too materialistic to do justice to an elevated pantheistic concept. Clifford’s conscious mind-stuff is sublimated materialism, and Ueberweg speaks of those “sensations” present in “inanimate” objects which are “concentrated” in the human brain, as if they represented so many substances to be weighed in scales. Instructive and thoughtful as is the discussion of this subject (pp. 32-63), its value would have been increased by a survey of the pantheistic schools of German speculation, so many of whose conclusions are absolutely at one with esoteric views as to the Logos and the metaphysics of consciousness.

After discussing the primary and secondary (so-called) qualities of matter, as tabulated by Mill, Hamilton and others, Mr. Sundaram Iyer passes on the question: “What is force?”

“Force is matter ... it may be related to matter in ... four ways:—firstly, it may be an extraneous power to matter, acting upon it from without; secondly, it may be an inherent power in matter, influencing it from within, but yet distinct from the substance of matter; thirdly, it may be an innate power in matter, influencing it from within, and not distinct from the substance of matter; or fourthly, it may be a function of the substance of matter.” (p. 76-7.)

After an interesting criticism of current theories, he concludes that:—

“Function is simply the phenomenal effect of the latent cause, namely force, but never force itself. This potential existence, which is in matter, is a physical existence. If not it cannot, as shown before, produce any impression whatsoever upon or in the substance of matter.”

Matter is force and force is matter. It is not quite evident, however, whether this position is strictly reconcilable with the remark that “the primary qualities of matter are all simplifiable into ... extension and (its) motion (actual or possible).”[possible).”]

If force is a physical existence, and the real substance of matter at the same time, we get back no further into the mystery of what things-in-themselves really are. Physical existence remains the reality behind physical existence and the realization of matter and force, as aspects only of one basis, in no way simplifies the crux.

It is not clear, moreover, what is the exact meaning the author intends by the use of the word “force.” Is it motion—molar or molecular—or the unknown cause of motion? According to Professor Huxley, “force” is merely an expression used to denote the cause of motion, whatever that may be. We only know this cause in its aspect of motion, and cannot penetrate behind the veil in order to grasp the Noumenon of which motion is the phenomenal effect. The necessity, therefore, of recognising the fact that motion is all that falls within the cognizance of sense, forbids the (profane) scientist to use the term “force” as representative of anything but an abstraction. The question is complicated by the consideration that the substantiality of various so-called “forces” appears most probable, and that this substantiality becomes objectively real to sense, only on a plane beyond this—the domain of matter in its order of physical differentiations.

The materialistic doctrine that force merely = a motion of matter is contradicted by the fact that, as shown by Mill, motion can be temporarily neutralized. Lift a heavy weight on to a shelf and the mechanical energy expended in the act is latent in the potentiality of the weight to fall to the ground again. There is no immediate equivalent, as the attraction of the earth for the object remains the same (the now greater distance tending to diminish the amount though in a very minute degree.)

It may be further noted that, granting Mr. Sundaram Iyer’s definition of matter as “extension pure and simple,” to be correct (p. 112), it is difficult to understand how he predicates this barren content as endowed with motion (p. 83.) What moves?
