 THE DOUBLE EFFECT OF MENTAL STIMULI. 817 river, the shop windows, the last number of Punch, and they pour themselves out on my unhappy mind these things when I am preaching a sermon, or otherwise seriously engaged." This kind of memory might be called subjective, following the hint that its associations are rooted in per- sonality. The kinetic excellence, on the other hand, is an orderly memory essentially objective, in which images are recalled with the emphasis on their associations, and in which lack of brilliance is compensated by liveliness. There will be varieties in such memory according to the predominant habit of thought, but it will always be relevant to some issue great or small. Whatever the dominant habit may be, the memory takes place through similarity always. Variety between persons arises in that preliminary part of the process which lias been barely mentioned, the analytic attention which deepens consciousness to association-point on one element of the new experience rather than another. Of this variety there is not time to speak now. In concluding the treatment of this subject one further suggestion remains to be made, though in a tentative spirit only. If consciousness corresponds to a particular kind of concentration and transformation of energy, with the effect of making the particular disturbance at one with all other disturbances of the same kind that has taken place in the individual life history, the extent of this transformation of energy does doubtless affect the form of the further dis- turbances following on it. The deeper consciousness probably initiates a wider spread activity reaching physio- logically it may be to parts of the brain left free from the regular play of the superficial kinesis parts which may be conceived as reverberating freely, not being devoted to particular sensory or motor functions as the other parts are. That there are such parts corresponding to the frontal lobes of the brain seems probable from physiological research. The suggestion here made is that when consciousness as such is intense these are more stimulated, and thus act as organs of reinforcement to consciousness more particularly, being not mapped out for any special processes of thought. This suggestion is consistent with the well-known observation that their development in man goes with mental power and also with the fact that their loss in animals is followed by motor function. If this be a view of the matter conforming to truth, the aesthetic type of mind compensates for the thinness of its
