Modern scientific evolutionary study of anthropology and history tends to confirm the hasty thinker in the idea that the circumstances of the environment completely determine the character and destiny of men, since their debt to the moulding influences of society and physical surroundings becomes more and more apparent; yet however powerful the environment may prove to be in fixing the direction of mental growth in the race, it cannot rightly be conceived as creating the growing forces. All the sunshine and warmth in the world will not cause a pebble to sprout; so no external influences whatever can develop mind where there is none to develop. The exigencies of Herbart’s metaphysics drove him into a crusade against Kant’s doctrine of innate freedom, or transcendental will; all the freedom that Herbart would admit was that psychological freedom which is acquired through instruction and training. The quarrel belongs to eighteenth-century metaphysics, not to modern psychology, nor to education; for however potentially free an infant may be, nobody thinks of making it responsible, except so far as growing experience gives it insight and volitional strength. =Note.=--Many thinkers fluctuate constantly between these two erroneous extremes. When looking historically at mankind as a whole, they arrive at fatalism, as does Gumplowicz in his “Outlines of Sociology.” Teacher and pupil alike seem to them to be in the current of a mighty stream, not swimming,--that is, self-active,--which would be the correct view, but carried along without wills of their own. They arrive, on the other hand, at the idea of a perfectly free will, when they contemplate the individual and see him resist external influences, the aims of the teacher very often included. Here they fail to comprehend the nature of will, and sacrifice the concept of natural law for that of will. Young teachers can hardly avoid sharing this uncertainty, favored as it is by the philosophies of the day; much is gained, however, when they are able to observe fluctuations of their own views without falling into either extreme. 6. The power of education must be neither over- nor under-estimated. The educator should, indeed, try to see how much may be done; but he must always expect that the outcome will warn him to confine his attempts within reasonable bounds. In order not to neglect anything essential, he needs to keep in view the practical bearings of the whole theory of ideas; in order to understand and interpret correctly the data furnished by observation of the child, the teacher must make constant use of psychology.
