It is true that to Froebel evolution is “the working of Divine Unity.” But there seems to be no special reason why this should invalidate what Froebel has to say, any more than Sir Oliver Lodge should be disqualified as a scientist, because he has produced a book in which he writes: “Development means unfolding latent possibilities … growth and development are in accordance with the law of the universe … the law of the universe and the will of God are here regarded as in some sort synonymous terms.” This is exactly Froebel’s position; he writes that “Nature and man have their origin in one and the same eternal Being, and their development takes place in accordance with the same laws, only at different stages.”--_E., p. 161._ That Froebel not only recognized the presence of instinct in human beings, but that he also saw, as Professor Wundt puts it, that this is “determined in parts by intelligence and volition,” he states very plainly: “Natural instinct and good example will do much, but here, as in all human concerns, one must proceed by extension of knowledge, and by careful scrutiny, or both the one and the other may mislead or be misdirected. Experience cries aloud to us, to warn us of this danger. _Assuredly man ought not to neglect his natural instincts, still less abandon them, but he must ennoble them through his intelligence, purify them through his reason._”--_L., p. 222._ “In the progress of development three stages differentiate themselves and fall apart; and these stages are seen both in individual men, and in the race as a whole. They are: (1) _Unconsciousness, the merely instinctive stage_; (2) _Vague Feeling, the tendency upwards towards consciousness_; and (3) _Relatively clear Conscious Intelligence_. Everything that is acquired by a great unity, say by a family, a community, a nation, must in its beginnings be acquired by the single members of that unity; and further it will take them in one of the three grades of development, either that of mere unconsciousness, or of vague feeling, or in the third and highest grade, that of conscious intelligence, so far as it has been maintained by mankind up to the present time.”--(Letter to Madame D. Lutkens, dated March, 1851.)
