We may begin upon this complex most hopefully by picking out a few of the conspicuous and typical elements and using them as a basis for an exhaustive classification. To begin with, of course, there is the home. For our present purpose it will be convenient to use “home” as a general expression for that limited group of human beings who share the board and lodging of the growing imperial citizen, and whose personalities are in constant, close contact with his until he reaches fifteen or sixteen. Typically, the chief figures of this group are mother, brothers and sisters, and father, to which are often added nursemaid, governess, and other servants. Beyond these are playmates again. Beyond these acquaintances figure. Home has indeed nowadays, in our world, no very definite boundaries--no such boundaries as it has, for example, on the veldt. In the case of a growing number of English upper middle-class children, moreover, and of the children of a growing element in the life of the eastern United States, the home functions are delegated in a very large degree to the preparatory school. It is a distinction that needs to be emphasized that many so-called schools are really homes, often very excellent homes, with which schools, often very inefficient schools, are united. All this we must lump together--it is, indeed, woven together almost inextricably--when we speak of home as a formative factor. The home, so far as its hygienic conditions go, we have already dealt with, and we have dealt, too, with the great neglected necessity, the absolute necessity if our peoples are to keep together, of making and keeping the language of the home uniform throughout our world-wide community. Purely intellectual development beyond the matter of language we may leave for a space. There remains the distinctive mental and moral function of the home, the determination by precept, example, and implication of the cardinal habits of the developing citizen, his general demeanour, his fundamental beliefs about all the common and essential things of life.
