Mental Overstrain in Education.—In a recent address before the British Medical Association, under the above title, Dr. G. E. Shuttleworth called attention to some of the harmful results caused by the undiscriminating educational methods of the public schools. He says: "With some so-called educationalists, I fear the idea still lingers that it" (education) "consists of cramming a mind with as much of as many subjects as possible. . . . A smattering of philology, however, will serve to show that the word ‘education’ means not putting in, but drawing out, and, bearing in mind the physiological interdependence of bodily and mental development, we may say that true education consists in processes of training which will produce in a given individual the most favorable evolution possible of all the faculties both of body and mind. A rational educational system will of course recognize the fact that all children are not cast in the same mold; that there are inherent, often inherited, differences in each pupil's powers, and that, to obtain the best results, instruction must be adapted to idiosyncrasies and proportioned to varying capacities. . . . From the medical standpoint we shall reply in the affirmative to the query of Plato: ‘Is not that the best education which gives to the mind and to the body all the force, all the beauty, and all the perfection of which they are capable?’ Overpressure in education may in brief be described as a neglect of the principles just set forth—a neglect which can not fail to lead to mental overstrain.
