Herbert Spencer was the first writer to subject Maine's hypothesis to a luminous criticism.[28] First he points out that Maine has not been entirely guiltless of "the lofty contempt" entertained by civilized peoples for their barbarous neighbors, which he himself censures as a serious error. For he "has practically disregarded the great mass of the uncivilized" peoples, and "ignored the vast array of facts they present at variance with his theory." Nor, in favor of a primitive patriarchal state, is it safe to assume that "the implicit obedience of rude men to their parents is doubtless a primary fact." For, "though among lower races, sons, while young, may be subordinate, from lack of ability to resist; yet that they remain subordinate when they become men cannot be assumed as a uniform, and therefore as a primary, fact." This objection is sustained by reference to many savage and barbarous tribes among which parents exercise little or no control over the children. Again, it is by no means established that "the history of political ideas begins, in fact, with the assumption that kinship in blood is the sole possible ground of community in political functions." On the contrary, "political co-operation arises from the conflicts of social groups with one another;"[29] and though it may be facilitated by a feeling of common descent, examples of political combination may be produced in which relationship is not considered. Furthermore, it is hard to conceive how so advanced a conception of government as is implied by the _patria potestas_ could exist in the "infancy of society;" nor has it yet been proved that in the primitive state the individual is entirely lost in the family group, which holds all property in common. Instances of "personal monopoly" of property among low races are not wanting. Finally the assumption that in the primordial state women remained in perpetual tutelage is without foundation; how far it is from the truth will be made clear in future chapters.[30] [28] _Principles of Sociology_, I, 713-37. [29] _Ibid._, 716, 717, 540-53. [30] See below, chap. iv. MR. SPENCER also points out that Maine does not take into account "stages in human progress earlier than the pastoral or agricultural."--_Op. cit._, I, 724 ff.
