Absurdities of immaterialism

by Orson Pratt

A unity of substance, consisting of parts, is supposed by Dr. Brown and other immaterialists to be, not only relatively, but absolutely absurd. But this supposed absurdity is only imaginary, and is founded wholly on supposition and false reasoning, and not on our self-consciousness. Self-consciousness teaches us the unity of self, but it does not teach us that a unity of self is inconsistent with a plurality of parts, and consequently inextended.

The absolute oneness or unity of a thinking being can, by no means, be denied. Every man in all the world,—the savage as well as the philosopher,—is conscious that what he calls himself is not many but one; but no man is conscious that the thinking substance called self does not consist of a plurality of parts—no one is conscious that self is inextended. Indeed, in the very notion of unity is involved the notion of a plurality of parts. In abstract numbers themselves a unit consists of an unlimited number of fractional parts. A unit of time is composed of innumerable parts called moments. A unit of space embraces a countless number of fractional spaces. A unit of substance is composed of an immense number of fractional parts. Without a plurality of parts we can form no notion whatsoever of unity. If consciousness, therefore, teaches us of the unity of self, it must teach us of a unity consisting of parts; otherwise it teaches us nothing. The unity of the thinking being, then, proves to a demonstration that it consists of parts, and consequently must be extended.

The term unity when applied to time, space, or substance, is entirely indefinite as to quantity. Any quantity, either great or small, may be assumed as a unit. In a multitude of human beings a man; in a bodily organ a molecule of any compounded substance which enters into its composition; and, in a molecule, an atom may be assumed as the unit. In an atom there is an indefinite number of parts, either of which may be chosen as a unit. But when we descend the scale still farther, and speak of that which has no parts, we can form no possible conception of a unit of inextension. The term nothing, instead of unity, is the only applicable term for that which is inextended. To think of unity in reference to external things, we think of something that has parts; so likewise to feel the unity of the mind is to feel that it has parts.

If the unity or oneness of the mind is any evidence in favor of its being inextended and without parts, the unity or oneness of all other substances is equal evidence of their inextension. All the atoms of every substance in the immensity of space, when considered separately and apart, are units, that is each atom is not many substances, but one. Therefore, if the unity of substance necessarily implies the inextension of substance, every atom in the universe must be inextended and without parts, and consequently immaterial.

If it be said that the universe contains no substances that can be called units, but that each atom is a plurality of substances, this would not obviate the difficulty in the least; it would only be adding absurdity to absurdity; for a plurality to exist without the possibility of a unity's existing, is inconceivable nonsense. A plural number, without a singular, or many substances to co-exist without the possibility of the existence of any single one, is as grossly absurd as immaterialism itself. Hence unity implies parts as much as plurality. Therefore, wherever a unity or plurality of substance exists, there matter exists, with all its essential characteristics.

No doubt but that the immaterialist absurdity was invented principally to combat the gross errors which have been embraced by some materialists, both of ancient and modern times. The great majority of materialists have contended that thought and feeling are the results of organization, beginning and ceasing with it. Hobbes, Spinosa, Priestley, Darwin, and numerous other individuals, have strenuously advocated this inconsistency. They have asserted that particles of matter have no susceptibilities of thought and feeling when unorganized, but as soon as they were brought together into a certain system, the result of such union is thought and feeling. Dr. Brown, in combating this vague conjecture, has clearly shown that a system of particles can have no properties as a whole which it does not possess in its individual parts; and, consequently, that a thought, or a joy, or a fear, or any other affections of the mind, cannot possibly be the affections resulting from a plurality, but in all cases must be the affections or feelings of every part of a substance. We most cordially believe with Dr. Brown, that a system of particles cannot possibly possess a property which the individuals composing the system do not possess. Had this great philosopher and metaphysician stopped here, his reasoning would have been amply sufficient to have overthrown the errors of Priestly, Darwin, and others who have supposed thought to begin and end with organization. But by supposing an individual unity to be inconsistent with extension and parts, he has advocated an absurdity still more glaring than the one which a part of his reasoning has so successfully overthrown.

There is another gross error of a very different nature from the one advocated by Priestley and his followers, which Dr. Brown also very clearly exposes. This error consists in assuming thought, hope, fear, joy, sorrow, desire, and all other affections to be little particles of matter. We are not aware, however, that there was ever a human being so void of common sense as to advocate this palpable inconsistency. It is very evident that this error is not necessarily incorporated with that absurd notion which supposes thought and other affections to be a property of an organized system of particles, but not a property of each individual particle. The two errors are widely different: the one supposes a thought or feeling to be a property, not of a single particle, but of a collection of particles; the other supposes a thought or feeling to be a little particle of matter itself, and not a property of either a particle or collection of particles. The former error has had numerous advocates in such men as Priestley, Darwin, &c.; but the latter, so far as we are aware, has had no advocates. Dr. Brown, however, has attacked not only the former, but the latter error, as though it really had an existence in some popular theory.

If thought be little particles of matter, Dr. Brown justly argues, "that it will be not more absurd to talk of the twentieth part of an affirmation, or the quarter of a hope, of the top of a remembrance, and the north and east corners of a comparison, than of the twentieth part of a pound, or of the different points of the compass in reference to any part of the globe of which we may be speaking." We agree with him most perfectly in saying, "that with every effort of attention which we can give to our mental analysis, we are as incapable of forming any conception of what is meant by the quarter of a doubt, or the half of a belief, as of forming to ourselves an image of a circle without a central point, or of a square without a single angle."

Dr. Brown also endeavours to bring this mode of reasoning to bear against the absurdity which supposes thought to be a quality of a collection of particles arranged in the form of an organ, but not a quality of single particles. But it is evident that the arguments which entirely demolish one error, leave the other entirely untouched. The weakness of Dr. Brown's argument, when wrongfully applied against the last-named error, will more fully appear by reference to his own words which read as follows:—

"Even though it were admitted, however, in opposition to one of the clearest truths in science, that an organ is something more than a mere name for the separate and independent bodies which it denotes, and that our various feelings are states of the sensorial organ, it must still be allowed that, if two hundred particles existing in a certain state form a doubt, the division of these into two equal aggregates of the particles, as they exist in this state at the moment of that particular feeling, would form halves of a doubt; that all the truths of arithmetic would be predicable of each separate thought, if it were a state of a number of particles."
