A champion of the transformation of pedagogy into a psycho-physiological science is to be found in Sweden in the person of Prof. Hjalmar Oehrwal who has discussed in his essays native and foreign discoveries in the field of psychology. One of his conclusions is that the so-called technical exercises, gymnastics, manual training, sloyd, and the like, are not, as they are erroneously called, a relaxation from mental overstrain by change in work, but simply a new form of brain fatigue. All work, he finds, done under conditions of fatigue is uneconomic whether one regards the quantity produced or its value as an exercise. Rest should be nothing more than rest,--freedom to do only what one wants to, or to do nothing at all. As to fear, he proves, following Binet's investigation in this subject, how corporal discipline, threats, and ridicule lead to cowardice; how all of these methods are to be rejected because they are depressing and tend to a diminution of energy. He shows, moreover, how fear can be overcome progressively, by strengthening the nervous system and in that way strengthening the character. This result comes about partly when all unnecessary terrorising is avoided, partly when children are accustomed to bear calmly and quietly the inevitable unpleasantnesses of danger. Prof. Axel Key's investigations on school children have won international recognition. In Sweden they have supplied the most significant material up to the present time for determining the influence of studies on physical development and the results of intellectual overstrain. It is to be hoped that when through empirical investigation we begin to get acquainted with the real nature of children, the school and the home will be freed from absurd notions about the character and needs of the child, those absurd notions which now cause painful cases of physical and psychical maltreatment, still called by conscientious and thinking human beings in schools and in homes, education.
