Extract

The first of these papers carried a warning against conceiving social order in an absolute sense. It does not mean suppression of all forms of competition and defeat, but only the protection of selected human interests at the expense of others. Even taking order in this limited sense, it was found that custom and voluntary adjustment furnishan incomplete apparatus for its furtherance. The effectiveness of custom was seen to be connected with the auxiliary activity of an organ of leadership to serve as a focus for the radiation of custom, and a pivot for change. Voluntary adjustment, while capable of resolving many interest-conflicts beyond the reach of custom, was also found to rely largely on the initiatory activity of an organ of mediation. Finally, we have thus far considered social order primarily from the point of view of the prevention or adjustment of direct conflicts of interests between individuals.

The functioning of a social group requires more than that its members should refrain from what other members resent as invasions of their interests. If the advantages of group life are to be reaped, it is necessary that at many points the group should, aswe say, act as a unit, which means that each member should so shape his conduct with reference to the conduct of others that the acts of all, when thus geared together, will produce an aggregate or group result. This gearing together of the acts of separate individuals is what is commonly called “coöperation.” Coöperation has value only as it furthers interests which belong to individuals.

But such a custom unlike other customs in that it is applicable only to a situation when a dispute has already occurred and blood is heated, is never as completely self-enforcing as customs of private every-day behavior (so-called “non-litigious” customs). It establishes an expectation without giving much assurance that the expectation will be satisfied. This is a characteristic of all customs which relate to the settlement of disputes until an authority is established to enforce them.

35 From practically the outset of group life, something approximating to a public criminal jurisdiction is almost always exercised by the group leadership in punishing individuals whose conduct threatens to bring disaster on the group. A striking example is the so-called “buffalo-police” among the Plains Indians. Lowie, , Primitive Society, p. 385Google Scholar. Offenses so punished were, however, almost always of a religious or sacral character, e.g., sorcery, divulging religious mysteries, etc. See Howitt, op. cit., pp. 297, 332, 341–344; Hobhouse, op. cit., pp. 88–92. “The evolution of criminal justice may be looked at as an extension of the conception of a tribal offense till it covers every serious wrong done to a single member of the tribe.” Ibid., p. 92.

37 “In the earliest time ‘right’ appeared to be of divine origin.” Hirtzel, R., Themis, Diké und Verwandtes (Leipzig, 1907)Google Scholar. Primitive man was sure there was a right, but he did not always claim to know it—he was content to leave such knowledge to the gods.

38 Primitive man's conception of divinity was broad enough to include much of what we mean by “personality,” in the sense of personal effectiveness. This quality of getting results was regarded as an indwelling divine power, to which the name orenda was applied among the Iroquois, and mana among the Melanesians. See Harrison, , Themis (Cambridge, 1912), pp. 6368Google Scholar. Professor Myres sees something of this notion of “drive” in the primitive conception of arché. op. cit., supra note 10, p. 158.

39 The doctrine that calamities, plagues, famines, etc., are proof that the ruler is displeasing to the higher powers survived far down into medieval political thought. See my Statesman's Book of John of Salisbury, p. lxx. For the idea in ancient China, see Wu, K. C., Ancient Chinese Political Theories (Shanghai, 1928), p. 14Google Scholar; in India, Ghoshal, op. cit., supra note 22, p. 140; in Greece, Homer's, Odyssey, xix, 108Google Scholar.

40 When the Homeric kings handed down their dooms, or “themistes,” the latter “were not framed in accordance with any body of law. Diké, or rightness, guided the royal judge” (Halliday, , Growth of the City State, p. 71Google Scholar) as he held the magic sceptre, while Themis, the “prudent counsel of the gods,” pointed out to him the practical advantages and disadvantages of the alternatives before him. For Themis in this sense, see Hirtzel, op. cit., supra note 37, pp. 4, 7–8, 9–11, 19; but see Weiss, E., Griechisches Privatrecht (Leipzig, 1923), i, 19Google Scholar. This conception is carried forward in later royalist thought in the theory of the king as “animate law” (Goodenough, op. cit., supranote 22, pp. 65 ff.). Law is not so much a known rule as the king's will for justice.

42 That the will of the gods was subject to a higher necessity was a common-place in the Greek conception of Moira, or fate. Burle, E., Notion de Droit Naturel dans l'Antiquité Grecque (Trevoux, 1908), 2831Google Scholar. It was an easy step from this notion to the conception of a body of “natural” law consisting of rules that could not be changed even by the gods themselves, i.e., an order of nature to which all rules of decision must conform. See Myres, op. cit., lecture v; Weiss, op. cit., i, 68 ff.

43 All primitive law rests on precedents, although this is not always recognized, because they are not written.

51 This was true, for example, of breaches of marriage customs, which, because they were supposed to bring on the community the wrath of the gods, were among many peoples subject to the early criminal jurisdiction discussed in note 35 supra, and in the passages in Howitt and Hobhouse there cited. So of the litigious customs referred to in note 32.

54 “The history of law is in effect the history of the critical moments in the changing of custom, and rules of law may be looked on as the accumulating deposit of the social solvents of custom.” Goitein, op. cit., p. 214.

56 It was also true of the government of the Hildebrandine papacy in the Church, which affords one of the most interesting instances of a successful war of authority against custom. See Fournier, P., “Un Tournant de l'Histoire de Droit,” in Nouvelle Revue de Droit François et Etranger, vol. 40, pp. 139141 (1916)Google Scholar.

57 As in the case of the alterations in cultural and economic interests which made possible and sustained the legal changes effected by the Revolutionary government of France.

58 “The creation of judges everywhere antedates the existence of formal law. But though formal law does not at first exist, the law itself exists, or there would be no occasion to appoint a judge to administer it.” Carter, J. C., “The Ideal and the Actual in the Law,” American Law Review, vol. 24, p. 759Google Scholar.

59 The fact that individuals settle their disputes without recourse to authority by no means implies that they settle them according to law, or that law exists, as seems to be often assumed, e.g., by Jung, , Das Problem des natürlichen Rechts, p. 98Google Scholar. One dispute may be brought to voluntary settlement with one result, another of substantially the same kind with a wholly different result. If uniform ways of adjusting disputes of the same kind grow up, as they occasionally do, they result in either a moral idea or a custom, which furnishes the raw material for a rule of law; but the difference is that such a custom or idea is followed only in the cases—not always numerous—where its content happens to satisfy both parties, while a law, whatever its content, appeals, because of its authoritative source, to all the interests connected with the maintenance of the group processes. Hence the difference in effectiveness between the rules of so-called international law and those of positive municipal law.

62 The intransigeance of such claims, supported by a subjective sense of right, is discussed by Goitein, op. cit., supra note 52, pp. 257, 258, and by Dewey, , Human Nature and Conduct, p. 83Google Scholar. Yet Jung undertakes to say: “The rules as to the existence or non-existence of a legal violation are derived and secondary; the obligation to lawful conduct does not exist because such rules exist, but these rules exist because the former obligation exists. Rules and concepts form themselves about uniform individual reactions which repeat themselves in similar situations because the individual members of a legal community react in a certain constant fashion to a particular kind of conduct.” op. cit., pp. 100–101. This is true in so far as law conforms to settled custom, but nowhere else. Hobbes placed his finger on the crux of the problem when he pointed out the need for “a common measure of all things that might fall in controversy; as, for example, of what is to be called right, what much, what little, what meum and tuum.” Elements of Law (ed. Tönnies, , Cambridge, 1928), pp. 149, 150Google Scholar.

64 Ibid., p. 93.

65 This is admitted by Jung, Ibid., pp. 102–103.

66 This confusion is enhanced by the legal doctrine, perfectly admissible if properly understood, which conceives a relation of principal and agent as existing between the organized community and its authoritative organ, and which therefore attributes to the former the acts of the latter. The identification was further promoted by the tendency of early thought to personify the group by a living symbol, god or king, which produced the view that the king was himself the state, or organized community. Goodenough, op. cit., supra note 22 p. 86. Finally, when various forms of “popular” participation in government were introduced, it became commonplace to conceive the community as acting not merely in a legal but in an actual sense, without realizing that it can so act only through some specific form of organization, i.e., through some official mouthpiece.

67 Thus, Jung is quite correct in pointing out that “a presupposition of the appearance of legal concepts is the existence of a community of members regarding one another with a certain amount of respect.” op. cit., p. 67.

68 According to Hirtzel, a recognition of this seems to have been a basic element in the Greek conception of diké, or “justice.” Diké “is the blow which, falling between the parties, has equal and impartial authority for both, through which therefore right appears to realize itself in opposition to strife. Upon the dark background of strife right brightens in the form of the decision of the judge which brings an end to contention.” op. cit., supra note 37, p. 103. “Diké points to a relationship between parties both of whom have rights—relationship in which right is not all on one side ….. The free intercourse between such parties is regulated by diké, which determines the limits of the opposing claims. There is always at the basis of the nation a judicial decision, actual or conceived. Where this does not reach, diké also ceases.” Ibid., p. 128. To the same general effect, Goitein, op. cit., supra note 52, pp. 265–275. See alsoHobbes, note 62 supra

69 For a good exposition of this view, see Jenks, , Law and Politics in the Middle Ages, pp. 295 ff.Google Scholar, where it is suggested that law as a social force is older than human society, and inhered in animal instinct. If law is taken as identical with the tendency to uniformity in conduct, such a view is admissible; but to take law in such a sense is to make it impossible to understand many of its more important characteristics.

70 “Before the law, then, we have justice without law, and after the law and during the evolution of law we still have it as a non-legal element under the name of discretion with reference to the requirements of individual cases.” Pound, , “Justice According to Law,” Columbia Law Review, vol. 13, p. 697Google Scholar. It is to conceal this element of discretion that the king is spoken of as “animate law,” supra note 40.

75 Simmel has pointed out the greater necessity for specialized organs of authority in larger than in smaller groups. “Small groups are characterizedby the fact that they require a larger participation on the part of individual members ….. Large groups are forced to build special structures to take over the function which the immediate reciprocity between elements fulfills in small circles. The social-unity can no longer be produced and preserved by the immediate relationships between individuals, and the large group must therefore build special organs in which the reciprocal activities and relationships of its elements can crystallize,” Spykman, N. J., The Social Theory of Georg Simmel (Chicago, 1925), pp. 136137Google Scholar. Therefore, in a large group, custom, voluntary adjustment, and informal leadership cannot produce order without authority in the way which is possible in small groups.

78a More and more, governmental intervention is taking the form of stimulating and guiding voluntary adjustment, rather than that of imposing authoritative standards.

79 On the other hand, it is not proper to assume, as many writers do, that the use of state authority represents a pathological condition. E.g., Jung, op. cit., supra note 59, p. 98. Resort to authority is as inevitable a social phenomenon as voluntary adjustment.

82 The matter has never been better put than by Professor MacIver: “Coercive power is the criterion of the state, but not its essence.” Op cit., supra note 76, p. 223. “It is true that there is no state where there is no overruling force. This is the differentia between the state and all other associations. There is no state where other associations arrogate to themselves the exercise of compulsion. But the exercise of force does not make a state.” Ibid., p. 230.
