=Religion Completes the Group.=--Conversely, this bond of union with unseen, yet ever present and powerful kindred spirits completed the group and gave to it its highest authority, its fullest value, its deepest sacredness. If the unseen kin are nature beings, they symbolize for man his dependence upon nature and his kinship in some vague fashion with the cosmic forces. If the gods are the departed ancestors, they are then conceived as still potent, like Father Anchises, to protect and guide the fortunes of their offspring. The wisdom, courage, and affection, as well as the power of the great heroes of the group, live on. The fact that the gods are unseen enhances tremendously their supposed power. The visible members of the group may be strong, but their strength can be measured. The living elders may be wise, yet they are not far beyond the rest of the group. But the invisible beings cannot be measured. The long-departed ancestor may have inconceivable age and wisdom. The imagination has free scope to magnify his power and invest him with all the ideal values it can conceive. The religious bond is, therefore, fitted to be the bearer, as the religious object is the embodiment in concrete form, of the higher standards of the group, and to furnish the sanction for their enforcement or adoption. § 6. GROUPS OR CLASSES ON THE BASIS OF AGE AND SEX While the kindred and family groups are by far the most important for early morality, other groupings are significant. The division by ages is widespread. The simplest scheme gives three classes: (1) children, (2) young men and maidens, (3) married persons. Puberty forms the bound between the first and second; marriage that between the second and third. Distinct modes of dress and ornament, frequently also different residences and standards of conduct, belong to these several classes. Of groups on the basis of sex, the _men's clubs_ are especially worthy of note. They flourish now chiefly in the islands of the Pacific, but there are indications, such as the common meals of the Spartans, of a wide spread among European peoples in early times. The fundamental idea[16] seems to be that of a common house for the unmarried young men, where they eat, sleep, and pass their time, whereas the women, children, and married men sleep and eat in the family dwelling. But in most cases all the men resort to the clubhouse by day. Strangers may be entertained there. It thus forms a sort of general center for the men's activities, and for the men's conversation. As such, it is an important agency for forming and expressing public opinion, and for impressing upon the young men just entering the house the standards of the older members. Further, in some cases these houses become the center of rites to the dead, and thus add the impressiveness of religious significance to their other activities.
