C. THE FOUR WISHES: A CLASSIFICATION OF SOCIAL FORCES

1. The Wish, the Social Atom[166]

The Freudian psychology is based on the doctrine of the "wish," just as physical science is based, today, on the concept of function. Both of these are what may be called dynamic concepts, rather than static; they envisage natural phenomena not as things but as processes and largely to this fact is due their pre-eminent explanatory value. Through the "wish" the "thing" aspect of mental phenomena, the more substantive "content of consciousness," becomes somewhat modified and reinterpreted. This "wish," which as a concept Freud does not analyze, includes all that would commonly be so classed, and also whatever would be called impulse, tendency, desire, purpose, attitude, and the like, not including, however, any emotional components thereof. Freud also acknowledges the existence of what he calls "negative wishes," and these are not fears but negative purposes. An exact definition of the "wish" is that it is a course of action which some mechanism of the body is set to carry out, whether it actually does so or does not. All emotions, as well as the feelings of pleasure and displeasure, are separable from the "wishes," and this precludes any thought of a merely hedonistic psychology. The wish is any purpose of project for a course of action, whether it is being merely entertained by the mind or is being actually executed—a distinction which is really of little importance. We shall do well if we consider this to be, as in fact it is, dependent on a motor attitude of the physical body, which goes over into overt action and conduct when the wish is carried into execution.

It is this "wish" which transforms the principal doctrines of psychology and recasts the science, much as the "atomic theory" and later the "ionic theory" have reshaped earlier conceptions of chemistry. This so-called "wish" becomes the unit of psychology, replacing the older unit commonly called "sensation," which latter, it is to be noted, was a content of consciousness unit, whereas the "wish" is a more dynamic affair.

Unquestionably the mind is somehow "embodied" in the body. But how? Well, if the unit of mind and character is a "wish," it is easy enough to perceive how it is incorporated. It is, this "wish," something which the body as a piece of mechanism can do—a course of action with regard to the environment which the machinery of the body is capable of carrying out. This capacity resides clearly in the parts of which the body consists and in the way in which these are put together, not so much in the matter of which the body is composed, as in the forms which this matter assumes when organized.

In order to look at this more closely we must go a bit down the evolutionary series to the fields of biology and physiology. Here we find much talk of nerves and muscles, sense-organs, reflex arcs, stimulation, and muscular response, and we feel that somehow these things do not reach the core of the matter, and that they never can; that spirit is not nerve or muscle; and that intelligent conduct, to say nothing of conscious thought, can never be reduced to reflex arcs and the like—just as a printing press is not merely wheels and rollers, and still less is it chunks of iron. The biologist has only himself to thank if he has overlooked a thing which lay directly under his nose. He has overlooked the form of organization of these his reflex arcs, has left out of account that step which assembles wheels and rollers into a printing press, and that which organizes reflex arcs, as we shall presently see, into an intelligent, conscious creature. Evolution took this important little step of organization ages ago, and thereby produced the rudimentary "wish."

Now in the reflex arc a sense-organ is stimulated and the energy of stimulation is transformed into nervous energy, which then passes along an afferent nerve to the central nervous system, passes through this and out by an efferent or motor nerve to a muscle, where the energy is again transformed and the muscle contracts. Stimulation at one point of the animal organism produces contraction at another. The principles of irritability and of motility are involved, but all further study of this process will lead us only to the physics and chemistry of the energy transformations—will lead us, that is, in the direction of analysis. If, however, we inquire in what way such reflexes are combined or "integrated" into more complicated processes, we shall be led in exactly the opposite direction, that of synthesis, and here we soon come, as is not surprising, to a synthetic novelty. This is specific response or behavior.

In this single reflex something is done to a sense-organ and the process within the organ is comparable to the process in any unstable substance when the foreign energy strikes it; it is strictly a chemical process, and so for the conducting nerve, likewise for the contracting muscle. It happens, as a physiological fact, that in this process stored energy is released so that a reflex contraction is literally comparable to the firing of a pistol. But the reflex arc is not "aware" of anything, and indeed there is nothing more to say about the process unless we should begin to analyze it. But even two such processes going on together in one organism are a very different matter. Two such processes require two sense-organs, two conduction paths, and two muscles; and since we are considering the result of the two in combination, the relative anatomical location of these six members is of importance. For simplicity I will take a hypothetical but strictly possible case. A small water animal has an eyespot located on each side of its anterior end; each spot is connected by a nerve with a vibratory silium or fin on the side of the posterior end; the thrust exerted by each fin is toward the rear. If, now, light strikes one eye, say the right, the left fin is set in motion and the animal's body is set rotating toward the right like a rowboat with one oar. This is all that one such reflex arc could do for the animal. Since, however, there are now two, when the animal comes to be turned far enough toward the right so that some of the light strikes the second eyespot (as will happen when the animal comes around facing the light), the second fin, on the right side, is set in motion, and the two together propel the animal forward in a straight line. The direction of this line will be that in which the animal lies when its two eyes receive equal amounts of light. In other words, by the combined operation of two reflexes the animal swims toward the light, while either reflex alone would only have set it spinning like a top. It now responds specifically in the direction of the light, whereas before it merely spun when lashed.

Suppose, now, that it possess a third reflex arc—a "heat spot" so connected with the same or other fins that when stimulated by a certain intensity of heat it initiates a nervous impulse which stops the forward propulsion. The animal is still "lashed," but nevertheless no light can force it to swim "blindly to its death" by scalding. It has the rudiments of "intelligence." But so it had before. For as soon as two reflex arcs capacitate it mechanically to swim toward light, it was no longer exactly like a pinwheel; it could respond specifically toward at least one thing in its environment.

It is this objective reference of a process of release that is significant. The mere reflex does not refer to anything beyond itself; if it drives an organism in a certain direction, it is only as a rocket ignited at random shoots off in some direction, depending on how it happened to lie. But specific response is not merely in some random direction, it is toward an object, and if this object is moved, the responding organism changes its direction and still moves after it. And the objective reference is that the organism is moving with reference to some object or fact of the environment. For the organism, while a very interesting mechanism in itself, is one whose movements turn on objects outside of itself, much as the orbit of the earth turns upon the sun; and these external, and sometimes very distant, objects are as much constituents of the behavior process as is the organism which does the turning. It is this pivotal outer object, the object of specific response, which seems to me to have been overneglected.
