I cannot follow out, in this introductory lecture, all his studies of the nature of man in these children, and all his experiments of cultivation. But I hope to do so in those which follow. The school founded in Keilhau exists to this day; but Frœbel ever found himself going back till at last he came to the infant in the mother's arms. Then he went into the huts of the peasantry to observe the mother's instinctive ways, reason upon them, purify them of her individual caprices and selfishness, and eliminate everything inconsistent with the divine idea and method of procedure, indicated by the instinct to the intelligence. He did not confine himself to Keilhau, where Middendorf steadily lived, though always keeping in relation with it; but went at times to other places, and once, for a year or two, left all, to go to the University of Göttingen to study philology. There he made himself acquainted with Greek, Latin, and Sanskrit, studying out those laws of mind exemplified in the formation and decay of languages. For it was the secret of a perfect development that he sought, and how to keep his pupils at the height they "were competent to gain." After half a century of the study of childhood in the living subject, and elaboration of the means of discipline, he settled in his old age into the conviction, that the most important period of human education was before the child was seven years old. And his last years were spent in preparing teachers for kindergartens at Rudolstadt and at Hamburg--which he did by teaching before them as well as by lecturing to them. Now it is what he discovered and elaborated, and has left, not in logical formulas, though he has certainly stated principles in words and embodied them in songs, but in processes of work and play, that is to be taught in our training schools. It took a Newton to discover gravitation and other principles of nature, but men without genius can comprehend and apply these principles, which they could not, like him, discover. So it took a Frœbel's genius to discover the first principles of education, and his sensibility to apply them without mistake; but intelligent and heartful young women can learn them and apply them, if--and only if--they will study devoutly and faithfully what he has taught; and in doing so they will find themselves--_not_ becoming artificial, but more profoundly natural than ever; for the true educational process is but the mother's instinct and method, clearly understood in all its bearings, and acted out. To be a kindergartner is the perfect development of womanliness--a working with God at the very fountain of artistic and intellectual power and moral character. It is therefore the highest finish that can be given to a woman's education, to be educated for a kindergartner; and it is from the most advanced classes of high and normal schools, public and private, that the pupils of our training schools should come, and from the most refined circles of private life--remembering that these are not identical with wealthy and fashionable ones, for in the latter we often find the vulgar and coarse. The refinement of feeling and thought which is always attended with gentle and courteous manners is a religious quality, that not seldom glorifies humble homes whose inmates escape the sometimes hardening effect of poverty by "seeing Him who is invisible," while those "the imagination of whose hearts are evil continually," and even the merely frivolous, betray that they have "faculties that they have never used" though they dwell in palaces.
