 activity which it stimulated by the double bondage to Aristotle and to the church. When the Reformation shook the traditional authority in one department, the blow was necessarily felt in the other. Not twenty years after Luther’s defiance of the pope, the startling thesis “that all that Aristotle taught was false” was prosperously maintained by the youthful Ramus before the university of Paris; and almost contemporaneously the group of remarkable thinkers in Italy who heralded the dawn of modern physical science—Cardanus, Telesio, Patrizzi, Campanella, Bruno—began to propound their Aristotelian theories of the constitution of the physical universe. It was to be foreseen that a similar assertion of independence would make itself heard in ethics also; and, indeed, amid the clash of dogmatic convictions, and the variations of private judgment, it was natural to seek for an ethical method that might claim universal acceptance from all sects.

C. Modern Ethics.—The need of such independent principles was most strongly felt in the region of man’s civil and political relations, especially the mutual relations of communities. Accordingly we find that modern ethical controversy began in a discussion of the law of nature. Albericus

Gentilis (1557–1611) and Hugo Grotius (1583–1645) were the first to give a systematic account. Natural law, according to Grotius and other writers of the age, is that part of divine law which follows from the essential nature of man, who is distinguished from animals by his “appetite” for tranquil association with his fellows, and his tendency to act on general principles. It is therefore as unalterable, even by God himself, as the truths of mathematics, although its effect may be overruled in any particular case by an express command of God; hence it is cognizable a priori, from the abstract consideration of human nature, though its existence may be known a posteriori also from its universal acceptance in human societies. The conception, as we have seen, was taken from the later Roman jurists; by them, however, the law of nature was conceived as something that underlay existing law, and was to be looked for through it, though it might ultimately supersede it, and in the meanwhile represented an ideal standard, by which improvements in legislation were to be guided. Still the language of the jurists in some passages (cf. Inst. of Justinian, ii. 1, 2) clearly implied a period of human history in which men were governed by natural law alone, prior to the institution of civil society. Posidonius had identified this period with the mythical “golden age”; and such ideas easily coalesced with the narrative in Genesis. Thus there had become current the conception of a “state of nature” in which individuals or single families lived side by side—under none other than those “natural” laws which prohibited mutual injury and interference in the free use of the goods of the earth common to all, and upheld parental authority, fidelity of wives, and the observance of compacts freely made. This conception Grotius took, and gave it additional force and solidity by using the principles of this natural law for the determination of international rights and duties, it being obvious that independent nations, in their corporate capacities, were still in that “state of nature” in their mutual relations. It was not, of course, assumed that these laws were universally obeyed; indeed, one point with which Grotius is especially concerned is the natural right of private war, arising out of the violation of more primary rights. Still a general observance was involved in the idea of a natural law as a “dictate of right reason indicating the agreement or disagreement of an act with man’s rational and social nature”; and we may observe that it was especially necessary to assume such a general observance in the case of contracts, since it was by an “express or tacit pact” that the right of property (as distinct from the mere right to non-interference during use) was held by him to have been instituted. A similar “fundamental pact” had long been generally regarded as the normal origin of legitimate sovereignty.

The ideas above expressed were not peculiar to Grotius; in particular the doctrine of the “fundamental pact” as the jural basis of government had long been maintained, especially in England, where the constitution historically established readily suggested such a compact. At the same time the rapid and remarkable success of Grotius’s treatise (De jure belli et pacis) brought his view of Natural Right into prominence, and suggested such questions as—“What is man’s ultimate reason for obeying these laws? Wherein exactly does this their agreement with his rational and social nature consist? How far, and in what sense, is his nature really social?”

It was the answer which Hobbes (1588–1679) gave to these fundamental questions that supplied the starting-point for independent ethical philosophy in England. The nature of this answer was determined by the psychological views to which Hobbes had been led, possibly to some extent under the influence of Bacon, partly perhaps through association with his younger contemporary Gassendi, who, in two treatises, published between the appearance of Hobbes’s De cive (1642) and that of the Leviathan (1651), endeavoured to revive interest in Epicurus. Hobbes’s psychology is in the first place materialistic; he holds, that is, that in any of the psycho-physical phenomena of human nature the reality is a material process of which the mental feeling is a mere “appearance.” Accordingly he regards pleasure as essentially motion “helping vital action,” and pain as motion “hindering” it. There is no logical connexion between this theory and the doctrine that appetite of desire has always pleasure (or the absence of pain) for its object; but a materialist, framing a system of psychology, will naturally direct his attention to the impulses arising out of bodily wants, whose obvious end is the preservation of the agent’s organism; and this, together with a philosophic wish to simplify, may lead him to the conclusion that all human impulses are similarly self-regarding. This, at any rate, is Hobbes’s cardinal doctrine in moral psychology, that each man’s appetites or desires are naturally directed either to the preservation of his life, or to that heightening of it which he feels as pleasure. Hobbes does not distinguish instinctive from deliberate pleasure-seeking; and he confidently resolves the most apparently unselfish emotions into phases of self-regard. Pity he finds to be grief for the calamity of others, arising from imagination of the like calamity befalling oneself; what we admire with seeming disinterestedness as beautiful (pulchrum) is really “pleasure in promise”; when men are not immediately seeking present pleasure, they desire power as a means to future pleasure, and thus have a derivative delight in the exercise of power that prompts to what we call benevolent action. Since, then, all the voluntary actions of men tend to their own preservation or pleasure, it cannot be reasonable to aim at anything else; in fact, nature rather than reason fixes this as the end of human action; it is reason’s function to show the means. Hence if we ask why it is reasonable for any individual to observe the rules of social behaviour that are commonly called moral, the answer is obvious that this is only indirectly reasonable, as a means to his own preservation or pleasure. It is not, however, in this, which is only the old Cyrenaic or Epicurean answer, that the distinctive point of Hobbism lies. It is rather in the doctrine that even this indirect reasonableness of the most fundamental moral rules is entirely conditional on their general observance, which cannot be secured apart from government. For example, it is not reasonable for me to perform my share of a contract, unless I have reason for believing that the other party will perform his; and this I cannot have, except in a society in which he will be punished for non-performance. Thus the ordinary rules of social behaviour are only hypothetically obligatory; they are actualized by the establishment of a “common power”
