And a forcible passage runs:

“Only if the child is treated through fostering his instinct for activity in the tri-unity of his nature, as living, loving, and perceiving, in the unity of his life, only thus can he develop as that which he is, the manifold and organized, but in himself single, whole.”—P., p. 12.

This development of the threefold yet single nature constitutes the “harmonious development,” reiterated ad nauseam and without explanation, in Kindergarten text-books. It is also the key to much that seems to us useless detail as to the toys and games of early childhood. The mother is told that:

“It is of the highest importance for the nurse to consider the earliest and slightest traces of the organization (Gliederung) within itself of the child’s mind as bodily, emotional and intellectual, that in his development from mere existence to perception and thought, none of these directions of his nature should be fostered at the expense of the other … the real foundation, the starting-point of human development is the heart and the emotions, but cultivation of action and thought (die Ausbildung zur That und zum Denken) must go side by side with it, constantly and inseparably: and thought must form itself into action, and action resolve and clear itself into thought; but both have their roots in the emotional nature.”[7]P., p. 42.

The first part of the following quotation from a letter written in 1851 towards the close of Froebel’s life might almost be taken from a text-book of the present day:

“We find also three attitudes, spheres of work, and regions of mind in man:

“(1) the region of the soul, the heart, Feeling;

“(2) the region of the mind, the head, Intellect;

“(3) the region of the active life, the putting forth to actual deed, Will.

“As mental attitudes these three divisions seem the wider apart the more we contemplate them; as spheres of work and regions of mind they seem quite separate and perfect opposites. But the highest and most absolute opposition is that which most needs, and necessitates reconciliation; complete opposites condition their uniting link. The need for the uniting link appears in almost every circumstance of life.… To satisfy that need is the most imperative need now set before the human race, … you will realize that the strengthening of character which we all agree to be a necessity of the age, is to be gained not only by stimulating and elevating the soul and the emotions, but by raising the whole mind, by training the intellect and the will.… Then the heart would acknowledge and esteem the intellectual power, just as the intellect already recognizes feeling as that which gives true warmth to our lives; and life as a whole would make manifest the soul which quickens existence, and gives it a meaning, as well as the intellect which gives it precision and culture. Intellect, feeling and will would then unite, a many-sided power, to build up and constitute our life. In the room of the unstable character which must result from the mere cultivation of the one department of emotion; in the room of the doubt, or, I might say empty negation, which too often proceeds from the mere cultivation of the intellect; in the room of the materialism, animalism, and sensuality which must come from the mere attention to the body, and physical side of our nature; we should then have the harmonious development of every side of our nature alike, we should then be able to build up a life which would be everywhere in touch with God, with physical nature, with humanity at large.”—L., p. 300.
