14 Yoo believes that the categories of ‘rogue’ and ‘failed’ state present different calculations, but for all intents and purposes he treats them as ‘targeted states’ in opposition with the Great Powers. Ultimately, such states become targets for war because they simply cannot muster an effective government (i.e., ‘unable’), or have an effective government but one that is crazy or evil or both (i.e., ‘unwilling’).

62 Though, for many commentators of a more ‘modern’ persuasion, the laws of war in the nineteenth century were more of a joke than anything else. The modern view of the laws of war, it is suggested, begins with the Hague Peace Conferences held at the turn of the twentieth century. As Brownlie has argued, international law before the First World War ceased to have any ‘limiting effect’ on the decisions of states to use violence against one another: I. Brownlie, International Law and the Use of Force by States (1963), 48: ‘The practice and doctrine of the period before 1920 present both a right of self-help and a right of self-preservation, the latter being unfortunately predominant and therefore obscuring the judicial value of the doctrine of self-help. This latter doctrine, which regarded war as a mode of judicial settlement, was nevertheless gaining ground in the period before the First World War. The greatest obstacle to adequate legal regulation of the use of force was the right of self-preservation and related tangle of doctrine concerning necessity and intervention. Categories such as self-preservation and necessity are too vague and susceptible to selfish interpretation to provide a sufficient basis for a legal regime. . .Lastly, the attempt to use vague categories of intervention and self-preservation to give a veneer of legality and morality to the exercise of the right of war or to the numerous interventions which occurred in this period obscured the situation and complicated the task of creating an adequate legal regime for the use of force.’: Ibid., at 48–9. See also, J.H.W. Verzijl, International Law in Historical Perspective (1968), 215 (‘Never until the twentieth century has the use of force been banned by positive international law, nor would it have even been possible to ban it in a society without any central authority to enforce the ban.’).

63 See, e.g., A. Anghie, Imperialism, Sovereignty, and the Making of International Law (2005). This mode of exclusion wasn't elaborated only in terms of self-interest. Rhetorically, at least, it was often couched in terms that suggested a progressive development available to the ‘inferior’ state. For example, Woolsey explained, ‘A state in the lower grade of civilization, like a savage, becomes conscious of its separate existence in the act of resistance, or of defending that existence. Such self-preservation on the part of the individual arouses, it may be, no better feeling than that of independence and self-reliance; in the state it helps the members to feel their unity and dependence, and the priceless value of the state itself. Hence war is a moral teacher: opposition to external force is an aid to the highest civic virtues.’ Woolsey, supra note 61, at 5. See also, L. Benton, A Search for Sovereignty: Law and Geography in European Empires 1400-1900 (2009).

64 Yoo, supra note 7, at 62.

65 Of course, it hardly needs saying that human beings have enslaved and exploited other human beings for as long as our history has been kept. But the point here is precisely that pre-liberal scholars like Vitoria did not use ‘race’, and that they could not have. Racial classifications were a distinctly liberal tactic. The point is that we can easily imagine a story in which liberalism created a new hunger for a means to maintain the subordination of certain human populations, while still able to retain the basic architecture of liberal rights for the more powerful groups. One way to do this could be found in the new turn to empirical science, and if it could be scientifically proven that certain humans were actually more ‘human’ than others, this would provide an effective means for circumscribing the Family of Nations. The invention of the human ‘races’ was the secret of the new liberal hierarchy, cloaking it in neutrality and necessity. The term ‘race’ is sometimes traced back to the work of Bernier in 1684, writing just 30 years after the 1651 publication of Hobbes’ Leviathan. F. Berneir, ‘A New Division of the Earth, according to the Different Species or Races of Men Who Inhabit It’, (1684) Journal des Scavans. Bernier, like the Comte de Buffon and Johann Friedrich Blumenbach who would later write the more popular texts on the physical ‘varieties’ of the human species, were all monogenecists. The major work of Georges-Louis Leclerc, Comte de Buffon, was Histoire naturelle, générale et particulière (1749–1788). Johan Blumenbach's central work here was On the Natural Variety of Humankind (1776). Good treatments of the history of race science include I. Hannaford, Race: The History of an Idea in the West (1996); N. Stepan, The Idea of Race in Science (1982); B. Baum, The Rise and Fall of the Caucasian Race (2006).

66 There are many instances of the use of race as a means of exclusion throughout US law, as well as at international law. On the domestic side, critical race theory has done the most in pursuit of the point. See, e.g., Gotanda, N., ‘A Critique of “Our Constitution is Colorblind”’, (1991) 44 Stanford Law Review 1 CrossRefGoogle Scholar. For helpful discussion of the point at a broader level, see T. McCarthy, Race, Empire, and the Idea of Human Development (2009). In terms of uses in the nineteenth century among international lawyers, see, e.g., W.E. Hall, A Treatise on International Law (1909), 52 (‘As has already been mentioned, international law is a product of the special civilization of modern Europe, and is intended to reflect the essential facts of that civilization so long as they are fit subjects for international rules. . .If it fails to do so, either through the imperfection of its civilization, or because the ideas, upon which it is founded, are alien to those of the European peoples, other states are at liberty to render its admission to the benefits of international law dependent on [the uncivilized state's willingness to conform to European values.]’); T.J. Lawrence, The Principles of International Law (1895) (‘. . .the notions of classical antiquity differ immensely from those of modern Europe, and in our own day there is a great gulf fixed between the views of European and American statesmen on the one hand and those of the potentates of Central Africa on the other. But though there are several systems of international law, there is but one important system. . .it grew up in Christian Europe, though some of its roots may be traced back to ancient Greece and ancient Rome. It has been adopted by all the civilized states of the earth. . .We have, therefore, in our definition, spoken of it as “the rules which determine the conduct of the general body of civilized states.”’) Ibid., at 4–5. Thus, Lawrence explained that even while certain populations might satisfy the criteria for statehood, sovereignty alone was insufficient to warrant ‘membership in the family of nations. For there are many communities outside the sphere of international law, though they are independent states. . .It would, for instance, be absurd to expect the King of Dahomey to establish a Prize Court, or to require the dwarfs of central African forest to receive a permanent diplomatic mission.’ Ibid., at 58. Whether they be ‘a race of savages’, or the more accomplished races of Turkey, China, or Japan, non-European peoples were presumptively inferior and outside the family of nations. Ibid., 58–9. J. Lorimer, The Institutes of the Law of Nations (1883), 101–2 (‘As a political phenomenon, humanity, in its present condition, divides itself into three concentric zones or spheres—that of civilized humanity, that of barbarous humanity, and that of savage humanity. . .It is with the first of these spheres alone that the international jurist has to deal. . .He is not bound to apply the positive law of nations to savages, or even to barbarians as such.’ In distinguishing between the civilized, barbarous, and savage spheres of humanity, Lorimer explained that it would be helpful to ‘distinguish between the progressive and non-progressive races’.).

69 Bluntschli cites Pritchard, Gobineau, and Waltz in his ‘scientific’ account of the racial composition of the law of nations. J.Bluntschli, The Theory of the State (2000), 76 (‘Highest in the scale stands the white race of Caucasian or Iranian nations, the “nations of the daylight”, as Carus calls them in opposition to the children of the night and of the twilight. . .They are preeminently the nations which determine the history of the world. All the higher religions which unite man with God were first revealed among them; almost all philosophy has issued from the works of their mind. In contact with other races they have always ended by conquering them and making them their subjects. They give the impulse to all higher political development. To their intellect and to the energy of their will, we owe, under God, all the highest achievements of the human spirit.’).

Again, my focus here links ‘pre-liberal jurisprudence’ exclusively with the medieval Aristotle. I do not mean to suggest that all modes of legal thought before Hobbes are ‘pre-liberal’ in the sense that I am describing here.

Nussbaum, A Concise History of the Law of Nations (1947), 109; R. Tuck, The Rights of War and Peace: Political Thought and the International Order from Grotius to Kant (2001).

107 This idea is at work in Maine's famous thought about the shift from ‘status to contract’, for example H. Maine, Ancient Law (1870). See also F. Hayek, The Constitution of Liberty (1978). Kennedy has framed the idea in his ‘will theory’ of law, where ‘[t]he state ought to and largely did in fact define the rules of law so as to guarantee the free exercise of individual will, subject to the constraint that willing actors respect the like rights of other willing actors.’ Kennedy, D., ‘From the Will Theory to the Principle of Private Autonomy: Lon Fuller's Consideration and Form’, (2000) 100 Columbia Law Review 94 CrossRefGoogle Scholar, at 96.

All natural beings have a natural end, a natural destiny, which determines what kind of operation is good for them.’).

111 See, e.g., H. Lauterpacht, International Law and Human Rights (1950), 114–15. As an aside, this is one reason why Yoo might associate early twentieth century institution building with Aristotelianism. At a surface level it might seem plausible to suggest that, since the moderns were expressly advocating for natural law prohibitions on war and other constraints on states, as well as a more consequentialist way of reasoning about international rules, Wilson and co. were resurrecting a pre-liberal Aristotelianism. As Yoo writes, ‘Wilson sought a revival of just war theory. In a manner reminiscent of the medieval philosophers, Wilson viewed aggressive war as a criminal activity. Defensive war represented prosecution and punishment of aggression.’ Yoo, supra note 7, 66. Now, I have little interest in what Wilson or House or anyone else ‘sought’ to revive, and we can leave this question to their biographers and intellectual historians. But with respect to the ‘manner’ in which the moderns sought to reconstruct a new international law – their style of legal argument – it is a mistake to see this manner as resembling pre-liberal Aristotelianism in any way but the weakest sense.

115 One important entryway into this new form of jurisprudence was provided by Wendell Holmes, Jr. in his ‘bad man’ jurisprudence. In this view, law was ‘valid’ so long as it actually mattered in the day-to-day of the man worried about law's sanction. ‘[A] legal duty so called is nothing but a prediction that if a man does or omits certain things he will be made to suffer in this or that way by judgment of the court.’ Holmes, O.

118 To be clear, it was not normal at all for modern thinkers to expressly argue for an international Leviathan in the Hobbesian style. Rather, my point is that for all of their raging against the Westphalian paradigm, it was unusual for the moderns to actually reject the liberal premises of the domestic analogy. As Kennedy has suggested in a different context, the moderns were interested in saving liberalism from itself, and not in its rejection.

141 A major intervention was made by Huxley and Haddon who published We Europeans in 1936. J. Huxley and A. Haddon, We Europeans (1936). Attacking the ‘pseudo-science’ of writers like Gobineau and Smith, Huxley and Haddon argued that the bulk of race science had been established to support the political, social, cultural, and economic superiority of some populations over others, and that as real science, the biology of race was complete nonsense, ibid., at 144–64. To be sure, they were not arguing that various populations could not be separated by innate genetic differences with regard to both physical and psychological traits – this would present an argument against race that would eventually come later in the century. But, where Huxley and Haddon admitted the existence of innate genetic differences between groups, they first challenged the non-sequitur that one could deduce psychological conditions from physical conditions, ibid., at 144. That is, there was no real evidence whatsoever that black skin or a certain cranial capacity could tell a scientist anything at all about ‘racial’ intelligence. Second, they criticized the idea that one could find average degrees of intelligence based on physiognomy – ‘there will be in every social class or ethnic group a great quantitative range and a great qualitative diversity of mental characters, and different groups will very largely overlap with each other’, ibid., at 70. Third, Huxley and Haddon suggested that whereas race science had previously concluded that ‘race is everything’ in the question of nature versus nurture, this was surely wrong. Climate and culture played an enormous role in the differentiation of human capabilities, and as yet, they concluded, there was simply no way of quantifying how explanatory nurture or nature might be in any given situation. While Huxley and Haddon agreed that there were innate differences between populations, and therefore kept within the discourse of a biological idea about the separation of groups of human beings, they believed that ‘nothing in the nature of “pure race” in the biological sense has any real existence’, ibid., at 14. Looking to Herodotus’ use of the term ethnos, Huxley and Haddon suggested ‘ethnic group’ to provide a superior way of labeling political, cultural, social, and economic differences between human populations, ibid., at 30–1.

142 Indeed, a formal veneer of sovereign equality came to become something like an ordering principle in the modern canon. Unlike in the context of the Family of Nations, where only those racially superior states enjoyed rights of territorial integrity and self-defence, the modern canon promulgated a new set of rules equally applicable to all members of the UN system. No better example is there than the UN Charter itself. In the first chapter of the Charter, the fourth paragraph of Art. 2 states: ‘All Members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inconsistent with the Purposes of the United Nations.’

143 Of course, and at the same time, the concept of equality was hardly self-evident in terms of how and where it ought to be applied. See, e.g., P. Potter, Introduction to the Study of International Organizations (1922), 254.

144 See, e.g., United Nations General Assembly Declaration on the Granting of Independence to Colonial Countries and Peoples (1960).

145 Speaking for a generation of lawyers, D.P. O'Connell stated in 1965 that ‘traditional institutions, consecrated by philosophical systems whose momentum is largely spent, and formed by political situations that are unlikely to be rejected, are called in question, and their historical evolution has been subjected to an analytical scrutiny that is unprecedented in legal scholarship.’ D. O'Connell, International Law (1970), ix. O'Connell's position is worthy of a bellwether for functionalism, given his stark differences with those advocates of the New International Economic Order, calling into question exactly the traditional institutions O'Connell himself appeared to believe had been spent. See, e.g., Second report on succession of states in respect of matters other than treaties, by Mr. Mohammed Bedjoui, Special Rapporteur: Economic and financial acquired rights and State succession’, UN Doc. A/CN.4/216/REV.1, 18 June 1969.
