Now Vico's genius was truly and indeed exclusively theoretical, and not at all practical or reformatory: his method was profoundly speculative and contemptuous of empiricism, his mind idealistic and opposed to materialism and utilitarianism: his theory of knowledge eager for the concrete, for "certitude," and, as such, of historical sympathies. Consequently his doctrine of the practical reason, though deriving its impetus from the theory of natural rights, was bound to emerge in a shape different from or even contrary to that theory in all the first four characteristics enumerated above. And if it did in one respect coincide--which it only does in the conclusion, not in the path by which the conclusion is reached--it did so in the very point in which Vico would least have wished it: in its immanental or anti-religious tendency. But since our subject is not the criticisms and modifications which the theory of natural right received from Vico's thought, but rather that thought itself, it is time to pick up the thread of the exposition, following an order somewhat different from that in which we have summed up the various characteristics of the theory, and beginning by observing Vico's opposition to the professed or implicit utilitarianism of the school, and the ethical doctrine by which he replaced it. The two chief representatives of utilitarianism in the seventeenth century, whom Vico always keeps in view, are Hobbes and Spinoza: but in addition to them, he refers to Locke and Bayle and, in the preceding century, Machiavelli; and going back to the ancients, the Stoics with their conception of faith and the Epicureans with that of chance, Carneades and his scepticism, and finally the unconscious theory contained in the saying "_Vae victis_" attributed to Brennus, chief of the Gauls who took Rome. He admired Hobbes's splendid attempt to enrich philosophy by a theory which had been lacking to the greatest days of Greece, the theory of man considered in the whole society of the human race: but he pronounced the result unsatisfactory, and the attempt, whose outcome, like that of Locke's system, was hardly distinguishable from Epicureanism, a failure. Hobbes did not observe that he could never have propounded his problem of the natural rights of mankind had not his motive been supplied by the Christian religion itself, which commands not indeed justice but charity to all mankind. With the Stoics on the other hand, with the fatalism and determinism which made it impossible for them to reason soundly about the state and laws, with the so-called "Spinozists of antiquity," he ideally united Spinoza; the uniqueness of whose utilitarianism, equally removed from the Lockian spirit and the Hobbist, since Spinoza "judges of the truth of things by the mind, not by sense" (_mente non sensu de veris rerum diiudicat_), did not escape Vico's notice. But unique though it was, it led Spinoza to think of the state in a somewhat undignified way
