Why has Sidgwick's political philosophy fallen into oblivion while his ethics continues to be celebrated? Not because his performance in that field was inferior, nor because his choice of topics has become outdated, nor because his conclusions were largely conservative. Instead the problem stems from the weight he attached to common sentiments and beliefs in his application of the utility principle, illustrated by his treatment of topics such as secession and colonialism. Moreover his Elements of Politics is arranged in such a way that he never has to confront the basic question of what makes states legitimate. This means that neither political moralists, who want to see the utility principle applied in more radical fashion, nor political realists, for whom the problem of establishing political order is central, find much to commend in his political philosophy.

Nor does he make an appearance in surveys that begin later, such as Hampsher-Monk, Iain, A History of Modern Political Thought: Major Political Thinkers from Hobbes to Marx (Oxford: Blackwell, 1992)Google Scholar or Forsyth, Murray and Keens-Soper, Maurice, The Political Classics: Green to Dworkin (Oxford: Oxford University Press, 1996)Google Scholar.
2 I am setting aside here his Outlines of the History of Ethics for English Readers, published in 1886, since this is a largely expository work, as well as the various collections of lectures that were published posthumously – as indeed was The Development of European Polity, though Sidgwick had intended to publish this in book form to complement The Elements of Politics.
3 Or unimportant: Sidgwick was inclined to doubt the success of any of his books. But we should probably set this aside as characteristic self-deprecation.
4 It has been claimed that Sidgwick's contribution to ethics also fell into neglect until revived in the second half of the twentieth century via the work of Rawls, Singer and others. However the evidence does not bear this out. Sidgwick's high standing among his immediate philosophical successors is discussed in Schultz, Bart, Henry Sidgwick: Eye of the Universe (Cambridge: Cambridge University Press, 2004), ch. 1CrossRefGoogle Scholar. In the first half of the following century his work was discussed by, among others, Broad, Prichard, Rashdall and Ross, and Rawls himself cites Sidgwick as early as 1955 in his paper ‘Two Concepts of Rules’.

6 The Elements of Politics seems to have attracted little attention outside Cambridge itself from the moment of its publication. For example, Ernest Barker's survey Political Thought in England from Herbert Spencer to the Present Day, published in 1915, contains not a single mention of Sidgwick's book. In the early twentieth century, it was dismissed as outmoded by critics such as Graham Wallas and Harold Laski: see Collini, Stefan, Winch, Donald and Burrow, John, That Noble Science of Politics (Cambridge: Cambridge University Press, 1983), EpilogueCrossRefGoogle Scholar.

Collini finds the ‘sustained architectonic command’ displayed in The Methods of Ethics missing in Sidgwick's later books.
10 Alongside the two reviews referred to below, The Elements of Politics received lukewarm notices from Rashdall, Hastings in The Economic Review 2 (1892), 275–78Google Scholar and Woodrow Wilson in The Dial, 12 (1891), 215–16. My concern here, however, is not with the book's immediate reception but with the reasons for its long-term neglect.

18 In the case of war, a slight shift occurs in his essay ‘The Morality of Strife’, first delivered as an address to the London Ethical Society in 1890, where Sidgwick urges ‘the thoughtful and moral part of every community’, without renouncing their patriotism, to try to judge international conflicts from an impartial point of view, so that resort to war can be avoided.

20 On the conservative, almost Burkean, character of Sidgwick's utilitarianism, see also Collini, Stefan, The Ordinary Experience of Civilized Life: Sidgwick's Politics and the Method of Reflective Analysis, in Essays on Henry Sidgwick, ed. by Schultz, Bart (Cambridge, 1992), pp. 333–67CrossRefGoogle Scholar, at pp. 349–52. Sidgwickian ethics is, of course, also largely conservative: the substance of ‘common sense morality’ emerges largely intact from Sidgwick's forensic examination. But I will argue that the problems this causes for his political philosophy are much more severe.
21 Formally it is divided into two parts, but my suggestion is that it is more illuminating to regard chapters 14–18 of Part I as separated from the chapters that precede them in terms of subject matter.

32 The most celebrated of such theories is, of course, Locke's, and it is more than a little frustrating that when Sidgwick discusses Locke's political theory in The Development of European Polity, he refrains from offering any critical assessment of Locke's account of consent to government.

40 For further reflection on this point, see Collini, The Ordinary Experience of Civilized Life, pp. 358–61. Collini cites Sidgwick's remark that his aim in Elements was ‘to treat systematically the chief questions for which the statesman has to find answers’ (italics added).

43 In his essay on ‘Public Morality’, Sidgwick argues that although public morality – the morality of statesmen – is not categorically different from private morality, nevertheless the circumstances of international politics mean that states are entitled to pursue their national interests by quite ruthless means unless they can be assured that other states will reciprocate their self-restraint.

48 There is some disagreement about the exact relationship between Sidgwick's methodology and Rawls's, but what is not in question is that Rawls at least took himself to be following in Sidgwick's footsteps when he expounded the method of reflective equilibrium.

53 Thus Singer is happy to reverse many of the practical conclusions that Sidgwick reaches – for example, his endorsement of various forms of partiality, towards kinsmen, compatriots, etc. – while continuing to treat Methods as the supreme statement of utilitarian philosophy: compare Singer, One World, ch. 5 with the Preface to Lazari-Radek and Singer, The Point of View of the Universe. This can only be done by disregarding Sidgwick's own conception of his method.
