One of the collateral advantages of such a view is that it removes some of the temptations to revert to animism from which psychologists, and especially literary psychologists, suffer. Dissatisfaction with current hypotheses as to the mechanism of reflex arcs is a main cause for the scientifically desperate belief in the soul. And apart from this, the special emotive factors which disturb judgment on this point are less obtrusive when this account is substituted for the usual story of the conditioned reflex, that sacrilegious contrivance of the mechanists.
There is no kind of mental activity in which memory does not intervene. We are most familiar with it in the case of images, those fugitive elusive copies of sensations with which psychology has been hitherto so much, perhaps too much, concerned. Visual images are the best known of them, but it is important to recognise that every kind of sensation may have its corresponding image. Visceral, kinæsthetic, thermal images can with a little practice be produced, even by people who have never noticed their occurrence. But individual differences as regards imagery are enormous, more in the degree to which images become conscious, however, than in their actual presence or absence on the needful occasion. Those people who, by their own report, are devoid of images, none the less behave in a way which makes it certain that the same processes are at work in them as in producers of the most flamboyant images.

The interventions of memory are not confined to sensation and emotion. They are of equal importance in our active behaviour. The acquisition of any muscular accomplishment, dancing or billiards, for example, shows this clearly. What we have already done in the past controls what we shall do in the future. If the perception of an object and the recognition that it is a tree, for example, involve a poise in the sensory system concerned, a certain completeness or ‘closure,’ to use the term employed by Kohler, so an act, as opposed to a random movement, involves a similar poise in a motor system. But sensory and motor systems are not independent; they work together; every perception probably includes a response in the form of incipient action. We constantly overlook the extent to which all the while we are making preliminary adjustments, getting ready to act in one way or another. Reading Captain Slocum’s account of the centipede which bit him on the head when alone in the middle of the Atlantic, the writer has been caused to leap right out of his chair by a leaf which fell upon his face from a tree. Only occasionally does some such accident show how extensive are the motor adjustments made in what appear to be the most unmuscular occupations.
This incipient activity stands to overt action much as an image stands to a sensation. But such ‘imaginal’ activity is, by its very nature, extraordinarily hard to detect or to experiment upon. Psychology has only dealt with fringes of the mind hitherto and the most accessible fringe is on the side of sensation. We have therefore to build up our conjectures as to the rest of mental happenings by analogy with the perhaps not entirely representative specimens which sensation supplies. This limitation has led the majority of psychologists to see in imaginal movement no more than images of the sensations from muscle, joint, and tendon, which would arise if the movement were actually made.
It is certain that before any action takes place a preliminary organisation must occur which ensures that the parts do not get in one another’s way. It appears to the writer that these preliminaries in his case make up part of consciousness, but there is a heavy weight of authority against him. The point is no doubt exceptionally hard to determine.
In any case, whether the consciousness of activity is due to sensations and images of movements alone, or whether the outgoing part of the impulse and its preparatory organisation help to make up consciousness, there is no doubt about the importance of incipient and imaginal movement in experience. The work done by Lipps, Groos and others on einfühlung, or empathy, however we may prefer to restate their results, shows that when we perceive spatial or musical form we commonly accompany our perception with closely connected motor activity. We cannot leave this activity out of our account of what happens in the experiences of the arts, although we may think that those who have built upon this fact what they have put forward as a complete æsthetic—Vernon Lee, for example—have been far from clear as to what questions they were answering.
The extent to which any activity is conscious seems to depend very largely upon how complex and how novel it is. The primitive and in a sense natural outcome of stimulus is action; the more simple the situation with which the mind is engaged, the closer is the connection between the stimulus and some overt response in action, and in general the less rich and full is the consciousness attendant. A man walking over uneven ground, for example, makes without reflection or emotion a continuous adjustment of his steps to his footing; but let the ground become precipitous and, unless he is used to such places, both reflection and emotion will appear. The increased complexity of the situation and the greater delicacy and appropriateness of the movements required for convenience and safety, call forth far more complicated goings on in the mind. Besides his perception of the nature of the ground, the thought may occur that a false move would be perilous and difficult to retrieve. This, when accompanied by emotion, is called a ‘realisation’ of his situation. The adjustment to one another of varied impulses—to go forward carefully, to lie down and grasp something with the hands, to go back, and so forth—and their co-ordination into useful behaviour alters the whole character of his experience.
Most behaviour is a reconciliation between the various acts which would satisfy the different impulses which combine to produce it; and the richness and interest of the feel of it in consciousness depends upon the variety of the impulses engaged. Any familiar activity, when set in different conditions so that the impulses which make it up have to adjust themselves to fresh streams of impulses due to the new conditions, is likely to take on increased richness and fullness in consciousness.
