=Note.=--Formerly, strange to say, no distinction was made between government and training, although it is obvious that the immediate present demands attention more urgently than does the future. Still less was instruction given its true place. The greater or smaller amount of knowledge, regarded as a matter of secondary importance in comparison with personal culture, was taken up last. The treatment of education as the development of character preceded that of instruction, just as though the former could be realized without the latter. During the last decades, however, a demand has arisen for greater activity on the part of schools, primarily the higher schools. Humanistic studies are to bestow humanity, or culture. It has come to be understood that the human being is more easily approached from the side of knowledge than from the side of moral sentiments and disposition. Furthermore, examinations might be set on the former, but not on the latter. Now the time for instruction was found to be too limited--a want that the old Latin schools had felt but little. This led to discussions as to the relative amount due each branch of study. We shall treat chiefly of the correlation of studies, for whatever remains isolated is of little significance. 59. In educative teaching, the mental activity incited by it is all important. This activity instruction is to increase, not to lessen; to ennoble, not to debase. =Note.=--A diminution of mental activity ensues, when, because of much study and of sitting--especially at all sorts of written work, often useless--physical growth is interfered with in a way sooner or later to the injury of health. Hence the encouragement given in recent years to gymnastic exercises, which may, however, become too violent. Deterioration sets in when knowledge is made subservient to ostentation and external advantages--the objectionable feature of many public examinations. Schools ought not to be called upon to display all they accomplish. By such methods instruction not only works against its own true end, but also conflicts with training, whose aim for the whole future of the pupil is--_mens sana in corpore sano_. 60. If all mental activity were of only one kind, the subject-matter of instruction would be of no consequence. But we need not go beyond experience to see that the opposite is true, that there is a great diversity of intellectual endowment. Yet while instruction must thus be differentiated, it should not be made so special as to cultivate only the more prominent gifts; otherwise the pupil’s less vigorous mental functions would be wholly neglected and perhaps suppressed. Instruction must rather be manifold, and its manifoldness being the same for many pupils in so far as it may help to correct inequalities in mental tendencies.
