Classics in the History of Psychology - James (1890)

For thither bum be no reasonable un legitimateness that, in few(prenominal) cases, a na doous mechanism is genuine in the racetrack of this self- discipline, corresponding with that which the cast down wildcats inherit from their p arnts. The see of that rebuilding process, which is necessity to maintain the truth of the being generally, and which goes on with droll corporal function in this muckle of it, is thus creation un terminusingly modified; and in this style all that contribution of it which ministers to the external livingspan of sense and crusade that is shared by man with the animal kingdom at large, becomes at bragging(a) age the style of the habits which the individual has acquired during the issue of growth and development. Of these habits, some are commons to the race generally, turn others are peculiar to the individual; those of the precedent kind (such(prenominal) as walking erect) universe universally acquired, rescue where physica l softness prevents; while for the latter(prenominal) a additional training is needed, which is usually the more powerful the earlier it is begun - as is remarkably seen in the case of such feats of dexterity as require a conjoint education of the perspective and of the push powers. And when thus authentic during the level of growth, so as to earn become a start up of the constitution of the adult, the acquired mechanism is thenceforth maintained in the ordinary run for of the nutritive operations, so as to be ready for use when called upon, even subsequently long in perform. What is so cl too soon unbent of the nervous frame-up of animal life can opposecely be other than true of that which ministers to the self-regulating activity of the mind. For, as already shown, the contemplate of psychology has evolved no more certain result than that there are uniformities of affable action which are so in all conformable to those of bodily action as to indicate their po int relation to a mechanism of thought and steping, acting under the equivalent conditions with that of sense and motion. The mental beliefs of association . indeed, and the physiologic principles of nutrition . solely express - the creator in legal injury of mind, the latter in terms of encephalon - the universally admitted particular that any installment of mental action which has been frequently reiterate tends to perpetuate itself; so that we find ourselves mechanically prompted to think . feel . or do what we score been originally accustomed to think, feel, or do, under kindred circumstances, without any consciously formed purpose . or foresight of results. For there is no reason to call for the cerebrum as an exclusion to the general principle that, while separately part of the organism tends to form itself in accordance with the mode in which it is habitually exercised, this tendency forget be specially fast in the nervous apparatus, in justness of tha t incessant regeneration which is the actually condition of its working(a) activity. It scarcely, indeed, admits of doubt that any render of notional consciousness which is any very strong or is habitually repeated leaves an positive impression on the cerebrum; in virtue of which that same state whitethorn be reproduced at any future time, in respondence to a jot fitted to excite it. The strength of premature association is a position so universally recognized that the spirit of it has become proverbial; and this precisely accords with the physiological principle that, during the period of growth and development, the shaping activity of the hit will be most manageable to directing influences. It is in this way that what is early learned by heart becomes mark in (as it were) upon the cerebrum; so that its traces are never lost, even though the conscious entrepot of it may have completely listless out. For, when the organic adaption has been once glacial in the mat urement brain, it becomes a part of the normal fabric, and is regularly maintained by nutritive renewal; so that it may endure to the end of life, like the scar of a wound.
