For instance, the children of your neighbours are likely to be the playmates of your own children, and the children of degenerate parents in the slum district of your city will possibly be the fellow-citizen partners of your own family. Again, when it is known that right or wrong nutrition of the body is the most important agent in forming character, in establishing predisposition to temperance or intemperance of living, including the desire for intoxicating stimulants, it is revealed to one that right nutrition of the community as a whole is an important factor in his own environment, as is self-care in the case of his own nourishment. The moment a student of every-day philosophy starts the study of problems from the A.B.C. beginning of things, and to shape his study according to an A.B.C. sequence, each cause of inharmony is at once traced back to its first expression in himself and then to causes influenced by his environments. If we find that the largest influences for good or bad originate with the right or wrong instruction of children during the home training or kindergarten period of their development, and that a dollar expended for education at that time is worth more for good than whole bancs of courts and whole armies of police to correct the effect of bad training and bad character later in life, it is quite logical to help promote the spread of the kindergarten or the kindergarten idea to include all of the children born into the world, and to furnish mothers and kindergarten teachers with knowledge relative to the right nutrition of their wards which they can themselves understand and can teach effectively to children. If we also find that the influence of the kindergarten upon the parents of the infants is more potent than any other which can be brought to bear upon them, we see clearly that the way to secure the widest reform in the most thorough manner is to concentrate attention upon the kindergarten phase of education, advocate its extension to include even the last one of the children, beginning with the most needy first, and extending the care outward from the centre of worst neglect to finally reach the whole. Experience in child saving so-called, and in child education on the kindergarten principle, has taught the cheapest and the most profitable way to insure an environment of good neighbours and profit-earning citizens; and investigation into the problem of human alimentation shows that a knowledge of the elements of an economic nutrition is the first essential of a family or school training; and also that this is most impressive when taught during the first ten years of life. One cannot completely succeed in the study of menticulture from its A.B.C. beginning and in A.B.C. sequence without appreciation of the interrelation of the physical and the mental, the personal and the social, in attaining a complete mastery of the subject.
