Utilitarianism is principally represented by English thought, to which belongs Hobbes, the greatest of all utilitarians, who proclaimed, _in statu naturae_ (that is to say, in genuine reality) _mensuram juris esse utilitatem._[1] Similar doctrines are to be found in Spinoza, who has also been looked upon and criticized as a pure utilitarian. But the matter is rather more complicated as regards Spinoza. Of him it should rather be said that he would have been the most resolute of ethical rigorists, had he ever been able to construct an Ethic. His determinism was an insuperable obstacle to this, for it does not admit distinctions of values, but considers the good. like being, in its abstractness, and therefore, the being of each one as _suum essere conservare_; hence the appearance of utilitarianism, assumed by the Ethic of Spinoza. [Sidenote: _English Ethic._] From Hobbes descend Locke, Hartley, Hume, Adam Smith, Warburton, Paley, and others such; they are all less courageous and less coherent philosophers than he. Indeed, if Hobbes himself could not but be incoherent and could not avoid causing a desire for and therefore a state of peace to arise from a state of nature or of war, whence is discovered to the mind a source of the practical, altogether different from that of the useful alone, which was presupposed; with the mean and sophistical efforts of his successors, the incoherence becomes altogether irritating. The aid sought from associationism is among these efforts, and the excogitation of the example of the miser (found for the first time in 1731, in a discourse of the Rev. John Gay),[2] and also the admission of the principle of sympathy beside that of egoism, a principle which with a cast of the dice is made to disappear again, and to become absorbed in egoism itself. The inanity of utilitarianism, which has already in Hobbes a tendency to disavow itself, by recognizing as true laws not those of nature, but those revealed by God (_in Scripturis sacris latae_),[3] and in Locke retained the divine side by side with the civil laws and those of public opinion,[4] became evident in the theological utilitarianism of Warburton and of Paley. As for intuitionists and psychologists, such as Shaftesbury, Hutcheson, Butler, these either left an unsolved dualism (as was above all the case with the last), or, although possessing the most lively consciousness of moral force, they yet strove to deduce it in some way from the egoistical and utilitarian principle. The French materialists of the eighteenth century, such as Helvétius and D'Holbach, though less subtle, are more consequent. [Sidenote: _Idealistic Philosophy._]
