can we overlook that exactly the same thing would then be necessary for every perception also? The outer impression produces, perhaps through eye or ear or skin, an excitement of the brain cell and this excitement is accompanied by a sensation; and no one fancies that the appearance of this sensation is dependent upon a special disposition for it on the mental side. No one fancies it, because it is evident that such a hypothesis again would be entirely useless. If every new perception needed such a special mental disposition, we should have to presuppose dispositions for everything which possibly can come into our surroundings. Every smell, every word, every face which comes anew to us would need its special ready-made disposition. In other words, our mind would contain the disposition for every possible idea and that would mean that these dispositions would be in no way helps for explanation. If the disposition exists for everything, no one particular thing can be explained by the existence of that disposition. Again we should have to rely entirely upon the physiological brain excitement for explaining that this word or that word is perceived by our mind. But if the brain excitement alone is sufficient to explain the new perception in the mind, then no reason can be found why the renewed brain excitement would not be sufficient to renew the mental experience. Thus there is nowhere room for mental dispositions below the level of consciousness.

Thirdly, what could we really mean by such mental dispositions? A physiological disposition for a physiological action is certainly not the action itself. The finger movement in piano playing finds only a disposition in my brain centers, in case I am trained; the movement itself does not last. But the disposition is at least itself a change in the physical world. The molecules are somehow differently placed, the disposition has thus as much objective existence as the resulting movement. Nothing at all similar can be imagined in the sphere of psychical contents. Such mental dispositions would have to exist entirely outside the world of concrete mental experiences and, if we scrutinize carefully, we soon discover that such theories are only lingering reminiscences of the purposive view of life, and do not fit at all into the causal one. If we take the purposive attitude, then every idea and every will contains indeed all that its meaning involves and everything which we can logically develop out of it is by intention contained in it. All mathematical calculations are then contained in the thought of figures and forms, but they are contained there only by intention, they are logically inclosed; psychologically the consciousness of the figures and forms does not contain any disposition for the development of mathematical systems. We indeed have no right to throw into a psychological subconsciousness all that which is not present but involved by intention in the ideas and volitions of our purposive life.

If thus the memory idea is linked with the past experience entirely by the lasting physiological change in the brain, we have no reason to alter the principle, when we meet the memory processes of the hypnotized person or the hysteric. It is true their memory may bring to light earlier experiences which are entirely forgotten by the conscious personality, but that ought to mean, of course, only that nerve paths have become accessible in which the propagation of the excitement was blocked up before. That does not bring us nearer to the demand for a subconscious mental memory. The threshold of excitability changes under most various conditions. Cells which respond easily in certain states may need the strongest stimulation in others. The brain cells which are too easily excited perhaps in maniacal exultation would respond too slowly in a melancholic depression. Hypnotism, too, by closing the opposite channels and opening wide the channels for the suggested discharge, may stir up excitements for which the disposition may have lingered since the days of childhood and yet which would not have been excited by the normal play of the neurons. Quite secondary remains the question of how these reproduced images finally appear in consciousness, that is, whether they appear with reference to earlier happenings and are thus felt as remembrances, or whether they enter as independent imaginations, or whether they finally, under special conditions, take the character of real, new perceptions. The latter case is well-known in crystal-gazing, where long-forgotten memory ideas project themselves into the visual field like hallucinations. But for the theory of the subconscious, even these uncanny crystal visions do not mean more than the simplest awakening of the experience of a landscape image of yesterday.

We turn to a second group of facts and again we have no fault to find with the observation of the facts, even of the most surprising and exceptional ones. Our objection refers to the interpretation of them. This second group contains the active results of such physiological nervous dispositions. In the first group, the dispositions come in question only as conditions for a new excitement which was accompanied by mental experience. In this second group, the dispositions are causes for other physiological processes which either lead to actions or to influences on other mental processes. The dispositions are here working like the setting of switches which turn the nervous process into special tracks. In the simple cases, of course no one doubts that a purely physiological basis is involved. The decapitated frog rubs its skin where it is touched with a drop of muriatic acid in a way which is ordinarily referred to the trained apparatus of his spinal cord, as no brain is left, and the usefulness of the action and its adjustment is very well understood as the result of the connecting paths in the nervous system.

From such simple adjustment of reactions of the spinal cord, we come step by step to the more complex activities of the subcortical brain centers, and finally to those which are evidently only short-cuts of the higher brain processes. That we react at every change of position with the right movements to keep our bodily balance, that we walk without thinking of our steps, that we speak without giving conscious impulse for the various speech movements, that we write without being aware of the motor activity which we had to learn slowly, that we play the piano without thinking of the special impulses of the hands, that we select the words of a hasty speech, if we have its aim in mind, without consciously selecting the appropriate words—all that is by continuous transitions connected with those simplest automatic reactions. And from here again, we are led over gradually perhaps to the automatic writings of the hysteric who writes complex messages without having any idea of their content in consciousness. It is in such cases certainly a symptom of disease that the activity of these lower brain centers can go over into the motor impulse of writing without producing secondary effects in the highest conscious brain centers; it is hysterical. But that the message of the pencil can be brought about by such operation of lower brain centers, or at least with imperfect coöperation of the higher brain centers, is certainly entirely within the limits of the same physiological explanation.

On the other hand, nothing is changed in the theoretic principles of the case if the effect of these automatic processes in the nervous system is not an external muscle action at first, but an influence on other brain centers which may furnish the consciousness with new contents. We try to remember a name, that is, a large number of neuron processes are setting in which normally lead to the excitement of that particular process which furnishes us the memory image of the name. But those brain cells may not respond, the channels may be blocked somehow or the excitability of those cells may be lowered. Now new excitements engage our psychophysical system. We are thinking of other problems. In the meantime, by the new equilibrium in the brain the blockade in these first paths may slowly disappear or the threshold of excitability may be changed. The physiological excitement may now be carried effectively into those tracts. The cell response sets in and suddenly the name comes to our mind. This purely physiological operation in our brain paths must thus have exactly the same result which it would have had, if more parts of the process had been accompanied by conscious experience. And again from mere remembering a forgotten name, we come by slow steps to the solution of a problem, to the invention, and finally to the creation of the genius.

Superficiality of thought is easily inclined to object to such a physiological interpretation and perhaps to denounce it pathetically as a crude materialism which lowers the dignity of mental work. Nothing shows more clearly the confusion between a purposive and causal view of the mind. In the purposive view of our real life, only our will and our personality have a meaning and can be related to the ideas and higher aims. Nature is there nothing but the dead material which is the tool of our will and which has to be mastered by the personality. In that world alone lie our duty and our morality. But as soon as we have gone over to the causal aspect of our life and have taken the point of view of the psychologist, making our inner life a series of contents of consciousness, of psychical phenomena, we have transformed our inner experience in such a way that it has become itself nothing but nature.

It is mental nature, nature of psychical stuff, but each part of it is nothing but a mental element, a mental atom without any meaning and without any value; nothing but a link in the chain, nothing but a factor in the explanation of the whole, nothing to which any ethical or æsthetic or logical or religious significance can any longer be attached. The psychical sensations and the physical atoms are equally material for naturalistic explanation. To understand causally a certain effect, for instance the creation of a work of art, of a discovery or a thought or a deed as the product of psychical processes, is thus in no way more dignified or more valuable than to understand it as the product of physiological brain processes. The one is not more dignified than the other because both alike have nothing whatever to do with dignity. Both alike are the necessary results of the foregoing processes, and to attach a kind of sentimental preference to the explanation through conscious factors is nothing but a confused reminiscence again of the entirely different purposive view of life. And surely nothing is gained for the higher values of life if this confusion sets in, because if the popular mind becomes unable to discriminate between the secondary, causal, artificial aspect of science and the primary, purposive aspect of life, the opposite effect lies still nearer: the values of the real life suffer and are crowded out by the knowledge of the scientific facts. Man's moral freedom is then wrongly brought in question, as soon as it is learned that every action is the product of brain processes. Life and science alike will gain the more, the more clearly the purposive and the causal point of view are separated and the more it is understood that this causal aspect itself is demanded by certain purposes of life. The oratory of those who denounce the physiological theories as lacking idealism in reality undermines true moral philosophy. There is no idealism which can really flourish merely by ignoring the progress of science and confusing the issues. The true values of the higher life cannot be safely protected by that thoughtless idealism
