DOES 'CONSCIOUSNESS' EXIST?[2]

'Thoughts' and 'things' are names for two sorts of object, which common sense will always find contrasted and will always practically oppose to each other. Philosophy, reflecting on the contrast, has varied in the past in her explanations of it, and may be expected to vary in the future. At first, 'spirit and matter,' 'soul and body,' stood for a pair of equipollent substances quite on a par in weight and interest. But one day Kant undermined the soul and brought in the transcendental ego, and ever since then the bipolar relation has been very much off its balance.

The transcendental ego seems nowadays in rationalist quarters to stand for everything, in empiricist quarters for almost nothing. In the hands of such writers as Schuppe, Rehmke, Natorp, Munsterberg--at any rate in his earlier writings, Schubert-Soldern and others, the spiritual principle attenuates itself to a thoroughly ghostly condition, being only a name for the fact that the 'content' of experience _is known_. It loses personal form and activity--these pa.s.sing over to the content--and becomes a bare _Bewusstheit_ or _Bewusstsein uberhaupt_, of which in its own right absolutely nothing can be said.

I believe that 'consciousness,' when once it has evaporated to this estate of pure diaphaneity, is on the point of disappearing altogether.

It is the name of a nonent.i.ty, and has no right to a place among first principles. Those who still cling to it are clinging to a mere echo, the faint rumor left behind by the disappearing 'soul' upon the air of philosophy. During the past year, I have read a number of articles whose authors seemed just on the point of abandoning the notion of consciousness,[3] and subst.i.tuting for it that of an absolute experience not due to two factors. But they were not quite radical enough, not quite daring enough in their negations. For twenty years past I have mistrusted 'consciousness' as an ent.i.ty; for seven or eight years past I have suggested its non-existence to my students, and tried to give them its pragmatic equivalent in realities of experience. It seems to me that the hour is ripe for it to be openly and universally discarded.

To deny plumply that 'consciousness' exists seems so absurd on the face of it--for undeniably 'thoughts' do exist--that I fear some readers will follow me no farther. Let me then immediately explain that I mean only to deny that the word stands for an ent.i.ty, but to insist most emphatically that it does stand for a function. There is, I mean, no aboriginal stuff or quality of being,[4] contrasted with that of which material objects are made, out of which our thoughts of them are made; but there is a function in experience which thoughts perform, and for the performance of which this quality of being is invoked. That function is _knowing_. 'Consciousness' is supposed necessary to explain the fact that things not only are, but get reported, are known. Whoever blots out the notion of consciousness from his list of first principles must still provide in some way for that function's being carried on.

I

My thesis is that if we start with the supposition that there is only one primal stuff or material in the world, a stuff of which everything is composed, and if we call that stuff 'pure experience,' then knowing can easily be explained as a particular sort of relation towards one another into which portions of pure experience may enter. The relation itself is a part of pure experience; one of its 'terms' becomes the subject or bearer of the knowledge, the knower,[5] the other becomes the object known. This will need much explanation before it can be understood. The best way to get it understood is to contrast it with the alternative view; and for that we may take the recentest alternative, that in which the evaporation of the definite soul-substance has proceeded as far as it can go without being yet complete. If neo-Kantism has expelled earlier forms of dualism, we shall have expelled all forms if we are able to expel neo-Kantism in its turn.

For the thinkers I call neo-Kantian, the word consciousness to-day does no more than signalize the fact that experience is indefeasibly dualistic in structure. It means that not subject, not object, but object-plus-subject is the minimum that can actually be. The subject-object distinction meanwhile is entirely different from that between mind and matter, from that between body and soul. Souls were detachable, had separate destinies; things could happen to them. To consciousness as such nothing can happen, for, timeless itself, it is only a witness of happenings in time, in which it plays no part. It is, in a word, but the logical correlative of 'content' in an Experience of which the peculiarity is that _fact comes to light_ in it, that _awareness of content_ takes place. Consciousness as such is entirely impersonal--'self' and its activities belong to the content. To say that I am self-conscious, or conscious of putting forth volition, means only that certain contents, for which 'self' and 'effort of will' are the names, are not without witness as they occur.

Thus, for these belated drinkers at the Kantian spring, we should have to admit consciousness as an 'epistemological' necessity, even if we had no direct evidence of its being there.

But in addition to this, we are supposed by almost every one to have an immediate consciousness of consciousness itself. When the world of outer fact ceases to be materially present, and we merely recall it in memory, or fancy it, the consciousness is believed to stand out and to be felt as a kind of impalpable inner flowing, which, once known in this sort of experience, may equally be detected in presentations of the outer world.

"The moment we try to fix our attention upon consciousness and to see _what_, distinctly, it is," says a recent writer, "it seems to vanish.

It seems as if we had before us a mere emptiness. When we try to introspect the sensation of blue, all we can see is the blue; the other element is as if it were diaphanous. Yet it _can_ be distinguished, if we look attentively enough, and know that there is something to look for."[6] "Consciousness" (Bewusstheit), says another philosopher, "is inexplicable and hardly describable, yet all conscious experiences have this in common that what we call their content has this peculiar reference to a centre for which 'self' is the name, in virtue of which reference alone the content is subjectively given, or appears ... While in this way consciousness, or reference to a self, is the only thing which distinguishes a conscious content from any sort of being that might be there with no one conscious of it, yet this only ground of the distinction defies all closer explanations. The existence of consciousness, although it is the fundamental fact of psychology, can indeed be laid down as certain, can be brought out by a.n.a.lysis, but can neither be defined nor deduced from anything but itself."[7]

'Can be brought out by a.n.a.lysis,' this author says. This supposes that the consciousness is one element, moment, factor--call it what you like--of an experience of essentially dualistic inner const.i.tution, from which, if you abstract the content, the consciousness will remain revealed to its own eye. Experience, at this rate, would be much like a paint of which the world pictures were made. Paint has a dual const.i.tution, involving, as it does, a menstruum[8] (oil, size or what not) and a ma.s.s of content in the form of pigment suspended therein. We can get the pure menstruum by letting the pigment settle, and the pure pigment by pouring off the size or oil. We operate here by physical subtraction; and the usual view is, that by mental subtraction we can separate the two factors of experience in an a.n.a.logous way--not isolating them entirely, but distinguishing them enough to know that they are two.

II

Now my contention is exactly the reverse of this. _Experience, I believe, has no such inner duplicity; and the separation of it into consciousness and content comes, not by way of subtraction, but by way of addition_--the addition, to a given concrete piece of it, of other sets of experiences, in connection with which severally its use or function may be of two different kinds. The paint will also serve here as an ill.u.s.tration. In a pot in a paint-shop, along with other paints, it serves in its entirety as so much saleable matter. Spread on a canvas, with other paints around it, it represents, on the contrary, a feature in a picture and performs a spiritual function. Just so, I maintain, does a given undivided portion of experience, taken in one context of a.s.sociates, play the part of a knower, of a state of mind, of 'consciousness'; while in a different context the same undivided bit of experience plays the part of a thing known, of an objective 'content.'

In a word, in one group it figures as a thought, in another group as a thing. And, since it can figure in both groups simultaneously we have every right to speak of it as subjective and objective both at once. The dualism connoted by such double-barrelled terms as 'experience,'

'phenomenon,' 'datum,' '_Vorfindung_'--terms which, in philosophy at any rate, tend more and more to replace the single-barrelled terms of 'thought' and 'thing'--that dualism, I say, is still preserved in this account, but reinterpreted, so that, instead of being mysterious and elusive, it becomes verifiable and concrete. It is an affair of relations, it falls outside, not inside, the single experience considered, and can always be particularized and defined.

The entering wedge for this more concrete way of understanding the dualism was fashioned by Locke when he made the word 'idea' stand indifferently for thing and thought, and by Berkeley when he said that what common sense means by realities is exactly what the philosopher means by ideas. Neither Locke nor Berkeley thought his truth out into perfect clearness, but it seems to me that the conception I am defending does little more than consistently carry out the 'pragmatic' method which they were the first to use.

If the reader will take his own experiences, he will see what I mean.

Let him begin with a perceptual experience, the 'presentation,' so called, of a physical object, his actual field of vision, the room he sits in, with the book he is reading as its centre; and let him for the present treat this complex object in the common-sense way as being 'really' what it seems to be, namely, a collection of physical things cut out from an environing world of other physical things with which these physical things have actual or potential relations. Now at the same time it is just _those self-same things_ which his mind, as we say, perceives; and the whole philosophy of perception from Democritus's time downwards has been just one long wrangle over the paradox that what is evidently one reality should be in two places at once, both in outer s.p.a.ce and in a person's mind. 'Representative' theories of perception avoid the logical paradox, but on the other hand they violate the reader's sense of life, which knows no intervening mental image but seems to see the room and the book immediately just as they physically exist.

The puzzle of how the one identical room can be in two places is at bottom just the puzzle of how one identical point can be on two lines.

It can, if it be situated at their intersection; and similarly, if the 'pure experience' of the room were a place of intersection of two processes, which connected it with different groups of a.s.sociates respectively, it could be counted twice over, as belonging to either group, and spoken of loosely as existing in two places, although it would remain all the time a numerically single thing.

Well, the experience is a member of diverse processes that can be followed away from it along entirely different lines. The one self-identical thing has so many relations to the rest of experience that you can take it in disparate systems of a.s.sociation, and treat it as belonging with opposite contexts.[9] In one of these contexts it is your 'field of consciousness'; in another it is 'the room in which you sit,' and it enters both contexts in its wholeness, giving no pretext for being said to attach itself to consciousness by one of its parts or aspects, and to outer reality by another. What are the two processes, now, into which the room-experience simultaneously enters in this way?

One of them is the reader's personal biography, the other is the history of the house of which the room is part. The presentation, the experience, the _that_ in short (for until we have decided _what_ it is it must be a mere _that_) is the last term of a train of sensations, emotions, decisions, movements, cla.s.sifications, expectations, etc., ending in the present, and the first term of a series of similar 'inner'

operations extending into the future, on the reader's part. On the other hand, the very same _that_ is the _terminus ad quem_ of a lot of previous physical operations, carpentering, papering, furnishing, warming, etc., and the _terminus a quo_ of a lot of future ones, in which it will be concerned when undergoing the destiny of a physical room. The physical and the mental operations form curiously incompatible groups. As a room, the experience has occupied that spot and had that environment for thirty years. As your field of consciousness it may never have existed until now. As a room, attention will go on to discover endless new details in it. As your mental state merely, few new ones will emerge under attention's eye. As a room, it will take an earthquake, or a gang of men, and in any case a certain amount of time, to destroy it. As your subjective state, the closing of your eyes, or any instantaneous play of your fancy will suffice. In the real world, fire will consume it. In your mind, you can let fire play over it without effect. As an outer object, you must pay so much a month to inhabit it. As an inner content, you may occupy it for any length of time rent-free. If, in short, you follow it in the mental direction, taking it along with events of personal biography solely, all sorts of things are true of it which are false, and false of it which are true if you treat it as a real thing experienced, follow it in the physical direction, and relate it to a.s.sociates in the outer world.

III

So far, all seems plain sailing, but my thesis will probably grow less plausible to the reader when I pa.s.s from percepts to concepts, or from the case of things presented to that of things remote. I believe, nevertheless, that here also the same law holds good. If we take conceptual manifolds, or memories, or fancies, they also are in their first intention mere bits of pure experience, and, as such, are single _thats_ which act in one context as objects, and in another context figure as mental states. By taking them in their first intention, I mean ignoring their relation to possible perceptual experiences with which they may be connected, which they may lead to and terminate in, and which then they may be supposed to 'represent.' Taking them in this way first, we confine the problem to a world merely 'thought-of' and not directly felt or seen.[10] This world, just like the world of percepts, comes to us at first as a chaos of experiences, but lines of order soon get traced. We find that any bit of it which we may cut out as an example is connected with distinct groups of a.s.sociates, just as our perceptual experiences are, that these a.s.sociates link themselves with it by different relations,[11] and that one forms the inner history of a person, while the other acts as an impersonal 'objective' world, either spatial and temporal, or else merely logical or mathematical, or otherwise 'ideal.'

The first obstacle on the part of the reader to seeing that these non-perceptual experiences have objectivity as well as subjectivity will probably be due to the intrusion into his mind of _percepts_, that third group of a.s.sociates with which the non-perceptual experiences have relations, and which, as a whole, they 'represent,' standing to them as thoughts to things. This important function of the non-perceptual experiences complicates the question and confuses it; for, so used are we to treat percepts as the sole genuine realities that, unless we keep them out of the discussion, we tend altogether to overlook the objectivity that lies in non-perceptual experiences by themselves. We treat them, 'knowing' percepts as they do, as through and through subjective, and say that they are wholly const.i.tuted of the stuff called consciousness, using this term now for a kind of ent.i.ty, after the fashion which I am seeking to refute.[12]

Abstracting, then, from percepts altogether, what I maintain is, that any single non-perceptual experience tends to get counted twice over, just as a perceptual experience does, figuring in one context as an object or field of objects, in another as a state of mind: and all this without the least internal self-diremption on its own part into consciousness and content. It is all consciousness in one taking; and, in the other, all content.

I find this objectivity of non-perceptual experiences, this complete parallelism in point of reality between the presently felt and the remotely thought, so well set forth in a page of Munsterberg's _Grundzuge_, that I will quote it as it stands.

"I may only think of my objects," says Professor Munsterberg; "yet, in my living thought they stand before me exactly as perceived objects would do, no matter how different the two ways of apprehending them may be in their genesis. The book here lying on the table before me, and the book in the next room of which I think and which I mean to get, are both in the same sense given realities for me, realities which I acknowledge and of which I take account. If you agree that the perceptual object is not an idea within me, but that percept and thing, as indistinguishably one, are really experienced _there, outside_, you ought not to believe that the merely thought-of object is hid away inside of the thinking subject. The object of which I think, and of whose existence I take cognizance without letting it now work upon my senses, occupies its definite place in the outer world as much as does the object which I directly see."

"What is true of the here and the there, is also true of the now and the then. I know of the thing which is present and perceived, but I know also of the thing which yesterday was but is no more, and which I only remember. Both can determine my present conduct, both are parts of the reality of which I keep account. It is true that of much of the past I am uncertain, just as I am uncertain of much of what is present if it be but dimly perceived. But the interval of time does not in principle alter my relation to the object, does not transform it from an object known into a mental state.... The things in the room here which I survey, and those in my distant home of which I think, the things of this minute and those of my long-vanished boyhood, influence and decide me alike, with a reality which my experience of them directly feels.

They both make up my real world, they make it directly, they do not have first to be introduced to me and mediated by ideas which now and here arise within me.... This not-me character of my recollections and expectations does not imply that the external objects of which I am aware in those experiences should necessarily be there also for others.

The objects of dreamers and hallucinated persons are wholly without general validity. But even were they centaurs and golden mountains, they still would be 'off there,' in fairy land, and not 'inside' of ourselves."[13]

This certainly is the immediate, primary, naf, or practical way of taking our thought-of world. Were there no perceptual world to serve as its 'reductive,' in Taine's sense, by being 'stronger' and more genuinely 'outer' (so that the whole merely thought-of world seems weak and inner in comparison), our world of thought would be the only world, and would enjoy complete reality in our belief. This actually happens in our dreams, and in our day-dreams so long as percepts do not interrupt them.

And yet, just as the seen room (to go back to our late example) is _also_ a field of consciousness, so the conceived or recollected room is _also_ a state of mind; and the doubling-up of the experience has in both cases similar grounds.

The room thought-of, namely, has many thought-of couplings with many thought-of things. Some of these couplings are inconstant, others are stable. In the reader's personal history the room occupies a single date--he saw it only once perhaps, a year ago. Of the house's history, on the other hand, it forms a permanent ingredient. Some couplings have the curious stubbornness, to borrow Royce's term, of fact; others show the fluidity of fancy--we let them come and go as we please.

Grouped with the rest of its house, with the name of its town, of its owner, builder, value, decorative plan, the room maintains a definite foothold, to which, if we try to loosen it, it tends to return, and to rea.s.sert itself with force.[14] With these a.s.sociates, in a word, it coheres, while to other houses, other towns, other owners, etc., it shows no tendency to cohere at all. The two collections, first of its cohesive, and, second, of its loose a.s.sociates, inevitably come to be contrasted. We call the first collection the system of external realities, in the midst of which the room, as 'real,' exists; the other we call the stream of our internal thinking, in which, as a 'mental image,' it for a moment floats.[15] The room thus again gets counted twice over. It plays two different roles, being _Gedanke_ and _Gedachtes_, the thought-of-an-object, and the object-thought-of, both in one; and all this without paradox or mystery, just as the same material thing may be both low and high, or small and great, or bad and good, because of its relations to opposite parts of an environing world.

As 'subjective' we say that the experience represents; as 'objective'

it is represented. What represents and what is represented is here numerically the same; but we must remember that no dualism of being represented and representing resides in the experience _per se_. In its pure state, or when isolated, there is no self-splitting of it into consciousness and what the consciousness is 'of.' Its subjectivity and objectivity are functional attributes solely, realized only when the experience is 'taken,' _i.e._, talked-of, twice, considered along with its two differing contexts respectively, by a new retrospective experience, of which that whole past complication now forms the fresh content.

The instant field of the present is at all times what I call the 'pure'

experience. It is only virtually or potentially either object or subject as yet. For the time being, it is plain, unqualified actuality, or existence, a simple _that_. In this _naf_ immediacy it is of course _valid_; it is _there_, we _act_ upon it; and the doubling of it in retrospection into a state of mind and a reality intended thereby, is just one of the acts. The 'state of mind,' first treated explicitly as such in retrospection, will stand corrected or confirmed, and the retrospective experience in its turn will get a similar treatment; but the immediate experience in its pa.s.sing is always 'truth,'[16] practical truth, _something to act on_, at its own movement. If the world were then and there to go out like a candle, it would remain truth absolute and objective, for it would be 'the last word,' would have no critic, and no one would ever oppose the thought in it to the reality intended.[17]

I think I may now claim to have made my thesis clear. Consciousness connotes a kind of external relation, and does not denote a special stuff or way of being. _The peculiarity of our experiences, that they not only are, but are known, which their 'conscious' quality is invoked to explain, is better explained by their relations--these relations themselves being experiences--to one another._

IV

Were I now to go on to treat of the knowing of perceptual by conceptual experiences, it would again prove to be an affair of external relations.

One experience would be the knower, the other the reality known; and I could perfectly well define, without the notion of 'consciousness,' what the knowing actually and practically amounts to--leading-towards, namely, and terminating-in percepts, through a series of transitional experiences which the world supplies. But I will not treat of this, s.p.a.ce being insufficient.[18] I will rather consider a few objections that are sure to be urged against the entire theory as it stands.

V

First of all, this will be asked: "If experience has not 'conscious'

existence, if it be not partly made of 'consciousness,' of what then is it made? Matter we know, and thought we know, and conscious content we know, but neutral and simple 'pure experience' is something we know not at all. Say _what_ it consists of--for it must consist of something--or be willing to give it up!"

To this challenge the reply is easy. Although for fluency's sake I myself spoke early in this article of a stuff of pure experience, I have now to say that there is no _general_ stuff of which experience at large is made. There are as many stuffs as there are 'natures' in the things experienced. If you ask what any one bit of pure experience is made of, the answer is always the same: "It is made of _that_, of just what appears, of s.p.a.ce, of intensity, of flatness, brownness, heaviness, or what not." Shadworth Hodgson's a.n.a.lysis here leaves nothing to be desired.[19] Experience is only a collective name for all these sensible natures, and save for time and s.p.a.ce (and, if you like, for 'being') there appears no universal element of which all things are made.
