The first of them I will call deliberation, in order to approximate it as closely as possible to the preceding decision. Having now my purpose decisively formed, I have to ask myself what physical means will best carry it out. I summon before my mind as complete a list as possible of nature's conveyances, and judge which of them will with the greatest efficiency and economy execute my intention. Here I am at a friend's house, but I have decided to go to my own. I must compare, then, the different modes of getting there, so as to pick out just that one which involves the least expenditure and the most certain result. One way occurs to me which I have never tried before, a swift and interesting way. I might go by balloon. In that balloon I could sail at my ease over the tops of the houses and across the beautiful river. When the tower of Memorial Hall comes in sight, I could pull a cord and drop gently down at my own door, having meanwhile had the seclusion and exaltation of an unusual ride. What a delightful experience! But there is one disadvantage. Balloons are not always at hand. I might be obliged to wait here for hours, for days, before getting one. I dismiss the thought of a balloon. It does not altogether suit my purpose.
Or, I might call a carriage. So I should secure solitude and a certain speed, but should pay for these with noise, jolting, and more money than I can well spare. There would be waiting, too, before the carriage comes. Perhaps I had better ask my friend to lend me his arm and to escort me home. In this there would be dignity and a saving of my strength. We could talk by the way, and I always find him interesting. But should I be willing to be so much beholden to him, and would not the wind to-day make our walk and talk difficult? Better postpone till summer weather. And after all there is Boston's most common mode of locomotion right at hand, the electric car. Strange it was not thought of before! The five-cent piece saved from the chocolates will carry me, swiftly, safely, and with independence.
It is in this way that we go through the process of deliberation. All the possible means of effecting our purpose are summoned for judgment. The feasibility of each is examined, and the cost involved in its employment. Comparison is made between the advantages offered by different agencies; and oftentimes at the close we are in a sad puzzle, finding these advantages and disadvantages so nearly balanced. One, however, is finally judged superior in fitness. To this we tie ourselves, making it the channel for our out-go. The whole process, then, in its detailed comparison and final fixation, is identical with that to which I have given the name of decision, except that the comparisons of decision refer to inner facts, those of deliberation to outer.

We now reach the climax of the whole process, effort, the actual sending forth through the deliberately chosen channel of the ideal desired and decided on. To it all the rest is merely preliminary, and in it the final move is made which commits us to the deed. About it, therefore, we may well desire the completest information. To tell the truth, I have none to give, and nobody else has. The nature of the operation is substantially unknown. Though something which we have been performing all day long, we and all our ancestors, no one of us has succeeded in getting a good sight of what actually takes place. Our purposes are prepared as I have described, and then those purposes—something altogether mental—change on a sudden to material motions. How is the transmutation accomplished? How do we pass from a mental picture to a set of motions in the physical world? What is the bridge connecting the two? The bridge is always down when we direct our gaze upon it, though firm when any act would cross.
Nor can we trace our passage any more easily in the opposite direction. When my eyes are turned on my watch, for example, the vibrations of light striking its face are reflected on the pupil of my eye. There the little motions, previously existing only in the surrounding ether, are communicated to my optic nerve. This vibrates too, and by its motion excites the matter of my brain, and then—well, I have a sensation of the white face of my watch. But what was contained in that then is precisely what we do not understand. Incoming motions may be transmuted into thought; or, as in effort, outgoing thought may be transmuted into motion. But alike in both cases, on the nature of that transmutation, the very thing we most desire to know, we get no light. In regard to this crucial point no one, materialist or idealist, can offer a suggestion. We may of course, in fault of explanation, restate the facts in clumsy circumlocution. Calling thought a kind of motion, we may say that in action it propagates itself from the mind through the brain into the outer world; while in the apprehension of an idea motions of the outer world pass into the brain, and there set up those motions which we know as thought. But after such explanations the mystery remains exactly where it was before. How does a "mental motion" come out of a bodily motion, or a bodily from a mental? It is wiser to acknowledge a mystery and to mark the spot where it occurs.
This marking of the spot may, however, illuminate the surrounding territory. If we cannot explain the nature of the crucial act, it may still be well to study its range. How widely is effort exercised? We should naturally answer, as widely as the habitable globe. I can sit in my office in Boston and carry on business in China. When I touch a button, great ships are loaded on the opposite side of the earth and cross the intervening oceans to work the bidding of a person they have never seen. Perhaps some day we may send our volition beyond the globe and enter into communication with the inhabitants of Mars. It would seem idle, then, to talk about the limitations of volition and a restricted range of will. But in fact that will is restricted, and its range is much narrower than the globe. For when we consider the matter, with precision, it is not exactly I who have operated in China. I operate only where I am. In touching the button my direct agency ceases. It is true that connected with that button are wires conducting to a wide variety of consequences. But about the details of that conduction I need know nothing. The wire will work equally well whether I understand or do not understand electricity. Its working is not mine, but its own. The pressure of my finger ends my act, which is then taken up and carried forward by automatic and mechanical adjustments requiring neither supervision nor consciousness on my part. We might then more accurately say that my direct volition is circumscribed by my own body. My finger tips, my lips, my nodding head are the points where I part with full control, though indefinitely beyond these I can forecast changes which the automatic agencies, once set astir, will induce.
Am I niggardly in thus confining the action of each of us within his own body? Is the range of volition thus marked out too narrow? On the contrary, it is probably still too wide. We are as powerless to direct our bodies as we are to manage affairs in China. This, at least, is the modern psychological doctrine of effort. It is now believed that volition is entirely a mental affair, and is confined to the single act of attention. It is alleged that when I attend to an ideal, fixing my mind fully upon it, the results are altogether similar to what occurred on my touching the button. Every idea tends to pass automatically into action through agencies about which I know as little as I do about ocean telegraphs. This physical frame of mine is a curious organic mechanism, in which reflex actions and instincts do their blind work at a hint from me. I am said to raise my arm. But never having been a student of anatomy and physiology, I have not the least idea how the rise was effected; and if I am told that nerves excite muscles, and these in turn contract like cords and pull the arm this way or that, the rise will not be accomplished a bit better for the information. For, as in electric transmission, it is not I who do the work. My part is attention. The rest is adapted automatism. When I have driven everything else out of my mind except the picture of the rising arm, it rises of itself, the after-effects on nerves and muscles being apprehended by me as the sense of effort.
We cannot, then, exercise our will with a wandering mind. So long as several ideas are conflictingly attended to, they hinder each other. This we verify in regrettable experiences every day. On waking this morning, for example, I saw it was time to get up. But the bed was comfortable, and there were interesting matters to think of. I meant to get up, for breakfast was waiting, and there was that new book to be examined, and that letter to be written. How long would this require, and how should the letter be planned? But I must get up. Possibly those callers may come. And shall I want to see them? It is really time to get up. What a curious figure the pattern of the paper makes, viewed in this light! The breakfast bell! Out of my head go all vagrant reflections, and suddenly, before I can notice the process, I find myself in the middle of the floor. That is the way. From wavering thoughts nothing comes. But suddenly some sound, some sight, some significant interest, raises the depicted act into exclusive vividness of attention, and our part is done. The spring has been touched, and the physical machinery, of which we may know little or nothing, does its work. There it stands ready, the automatic machinery of this exquisite frame of ours, waiting for the unconfused signal,—our only part in the performance,—then automatically it springs to action and pushes our purpose into the outer world. Such at least is the fashionable teaching of psychologists to-day. Volition is full attention. It has no wider scope. With bodily adjustments it does not meddle. These move by their own mechanic law. Of real connection between body and mind we know nothing. We can only say that such parallelism exists that physical action occurs on occasion of complete mental vision.
