It is quite likely that I shall be reminded that I am overlooking an essential difference. The physician, it will be said, is dealing with a body which either is in itself a pure object, a causal interplay of anatomical elements, or is something which lends itself naturally and without essential loss to treatment from this point of view; while the case is quite different in the material with which the teacher deals. Here is personality, which is destroyed when regarded as an object. But the gap is not so pronounced nor so serious as this objection implies. The physician, after all, is not dealing with a lifeless body; with a simple anatomical structure, or interplay of mechanical elements. Life-functions, active operations, are the reality which confronts him. We do not have to go back many centuries in the history of medicine to find a time when the physician attempted to deal with these functions directly and immediately. They were so overpoweringly present, they forced themselves upon him so obviously and so constantly, that he had no resource save a mixture of magic and empiricism: magic so far as he followed methods derived from uncritical analogy, or from purely general speculation on the universe and life; empiricism so long as he just followed procedures which had been found helpful before in cases which somewhat resembled the present. We have only to trace the intervening history of medicine to appreciate that it is precisely the ability to state function in terms of structure, to reduce life in its active operations to terms of a causal mechanism, which has taken the medical calling out of this dependence upon a vibration between superstition and routine. Progress has come by taking what is really an activity _as if_ it were only an object. It is the capacity to effect this transformation of life-activity which measures both the scientific character of the physician's procedure and his practical control, the certainty and efficacy of what he, as a living man, does in relation to some other living man.
It is an old story, however, that we must not content ourselves with analogies. We must find some specific reason in the principles of the teacher's own activities for believing that psychology--the ability to transform a living personality into an objective mechanism for the time being--is not merely an incidental help, but an organic necessity. Upon the whole, the best efforts of teachers at present are partly paralyzed, partly distorted, and partly rendered futile precisely from the fact that they are in such immediate contact with sheer, unanalyzed personality. The relation is such a purely ethical and personal one that the teacher cannot get enough outside the situation to handle it intelligently and effectively. He is in precisely the condition in which the physician was when he had no recourse save to deal with health as entity or force on one side, and disease as opposing agency or invading influence upon the other. The teacher reacts _en bloc_, in a gross wholesale way, to something which he takes in an equally undefined and total way in the child. It is the inability to regard, upon occasion, both himself and the child as just objects working upon each other in specific ways that compels him to resort to purely arbitrary measures, to fall back upon mere routine traditions of school-teaching, or to fly to the latest fad of pedagogical theorists--the latest panacea peddled out in school journals or teachers' institutes--just as the old physician relied upon his magic formula.
