tinct forms when they first appear. Contrariwise, we must expect them to begin in vague, unsettled forms. Arising as they do by modification of preëxisting structures, they are necessarily long in losing all trace of these. For example, transition from the state in which the laborer, owned like a beast, is maintained that he may work exclusively for his master's benefit, to the condition in which he is completely detached from master, soil, and locality, and free to work anywhere and for any one, is through gradations. Again, the change from the arrangement proper to militancy, under which subject-persons receive, in addition to maintenance, occasional presents, to the arrangement under which, in place of both, they receive fixed wages, or salaries, or fees, goes on slowly and unobtrusively. Once more it is observable that the process of exchange, originally indefinite, has become definite only where industrialism is considerably developed. Barter did not begin with a distinct intention of giving one thing for another thing equivalent in value, but it began by making a present and receiving a present in return; and even now in the East there continue traces of this primitive transaction. In Cairo the purchase of articles from a shopkeeper is preceded by his offer of coffee and cigarettes; and, during the negotiation which ends in the engagement of a dahabeah, the dragoman brings gifts and expects to receive them. Add to which that there exists under such conditions none of that definite equivalence which characterizes exchange among ourselves: prices are not fixed, but vary widely with every fresh transaction. So that, throughout our interpretations, we must keep in view the truth that the structures and functions proper to the industrial type distinguish themselves but gradually from those proper to the militant type.
Having thus prepared the way, let us now consider what are, a priori, the traits of that social organization which, entirely unfitted for carrying on defense against external enemies, is exclusively fitted for maintaining the life of the society by subserving the lives of its units. As before, in treating of the militant type, so here, in treating of the industrial type, we will consider first the ideal form.
While corporate action is the primary requirement in a society which has to preserve itself in presence of hostile societies, conversely, in the absence of hostile societies, corporate action is no longer the primary requirement.
The continued existence of a society implies, first, that it shall not be destroyed bodily by foreign foes, and implies, second, that it shall not be destroyed in detail by failure of its members to support and propagate themselves. If danger of destruction from the first cause ceases, there remains only danger of destruction from the second cause. Sustentation of the society will now be achieved by the self-sustentation and multiplication of its units. If his own welfare and
