Ethics, accordingly, in Hobbes's eyes, is part of the science of man (as a natural body), and it is always treated as such. But subjecting, as he does, so much of the action of the individual to the action of the state, he necessarily includes in his Politics many questions that usually fall to Ethics. Hence arises the necessity of studying for his Ethics also part of the civil Philosophy; though it happens that, in the Leviathan, this requisite part is incorporated with the Section containing the Science of Man.
Chapter X. is on Power, Worth, Dignity, Honour, and Worthiness. A man's power being his present means to obtain some future apparent good, he enumerates all the sources of original and acquired power. The worth of a man is what would be given for the use of his power; it is, therefore, never absolute, but dependent on the need and judgment of another. Dignity is the value set on a man by the state. Honour and dishonour are the manifestation of value. He goes through all the signs of honour and dishonour. Honourable is any possession, action, or quality that is the sign of power. Where there is the opinion of power, the justice or injustice of an action does not affect the honour. He clearly means a universally accepted opinion of power, and cites the characters of the pagan deities. So, too, before times of civil order, it was held no dishonour to be a pirate, and even still, duels, though unlawful, are honourable, and will be till there be honour ordained for them that refuse. Farther on, he distinguishes Worthiness, (1) from worth, and (2) from merit, or the possession of a particular ability or desert, which, as will be seen, presupposes a right to a thing, founded on a promise.
Chapter XI. bears the title, Of the difference of Manners; by manners being meant, not decency of behaviour and points of the 'small morals,' but the qualities of mankind that concern their living together in peace and unity. Felicity of life, as before, he pronounces to be a continual progress of desire, there being no finis ultimus nor summum bonum. The aim of all men is, therefore, not only to enjoy once and for an instant, but to assure for over the way of future desire. Men differ in their way of doing so, from diversity of passion and their different degrees of knowledge. One thing he notes as common to all, a restless and perpetual desire of power after power, because the present power of living well depends on the acquisition of more. Competition inclines to contention and war. The desire of ease, on the other hand, and fear of death or wounds, dispose to civil obedience. So also does desire of knowledge, implying, as it does, desire of leisure. Desire of praise and desire of fame after death dispose to laudable actions; in such fame, there is a present delight from foresight of it, and of benefit redounding to posterity; for pleasure to the sense is also pleasure in the imagination. Unrequitable benefits from an equal engender secret hatred, but from a superior, love; the cheerful acceptation, called gratitude, requiting the giver with honour. Requitable benefits, even from equals or inferiors, dispose to love; for hence arises emulation in benefiting—'the most noble and profitable contention possible, wherein the victor is pleased with his victory, and the other revenged by confessing it.' He passes under review other dispositions, such as fear of oppression, vain-glory, ambition, pusillanimity, frugality, &c., with reference to the course of conduct they prompt to. Then he comes to a favourite subject, the mistaken courses whereinto men fall that are ignorant of natural causes and the proper signification of words. The effect of ignorance of the causes of right, equity, law, and justice, is to make custom and example the rule of actions, as with children, or to induce the setting of custom against reason, and reason against custom, whereby the doctrine of right and wrong is perpetually disputed, both by the pen, and by the sword. Again, taking up ignorance of the laws of nature, he is led on to the subject of natural Religion, and devotes also the whole of Chapter XII. to Religion and kindred topics.
In Chapter XIII., he deals with the natural condition of Mankind, as concerning their Felicity and Misery. All men, he says, are by nature equal. Differences there are in the faculties of body and mind, but, when all is taken together, not great enough to establish a steady superiority of one over another. Besides even more than in strength, men are equal in prudence, which is but experience that comes to all. People indeed generally believe that others are not so wise as themselves, but 'there is not ordinarily a greater sign of equal distribution of anything than that every person is contented with his share.'
Of this equality of ability, the consequence is that two men desiring the exclusive possession of the same thing, whether for their own conservation or for delectation, will become enemies and seek to destroy each other. In such a case, it will be natural for any man to seek to secure himself by anticipating others in the use of force or wiles; and, because some will not be content with merely securing themselves, others, who would be content, will be driven to take the offensive for mere self-conservation. Moreover, men will be displeased at being valued by others less highly than by themselves, and will use force to extort respect.
Thus, he finds three principal causes of quarrel in the nature of man—competition, diffidence (distrust), and glory, making men invade for gain, for safety, and for reputation. Men will accordingly, in the absence of any power to keep them in awe, be in a constant state of war; by which is meant, not actual fighting, but the known disposition thereto, and no assurance to the contrary.
He proceeds to draw a very dismal picture of the results of this state of enmity of man against man—no industry, no agriculture, no arts, no society, and so forth, but only fear and danger of violent death, and life solitary, poor, nasty, brutish, and short. To those that doubt the truth of such an 'inference made from the passions,' and desire the confirmation of experience, he cites the wearing of arms and locking of doors, &c., as actions that accuse mankind as much as any words of his. Besides, it is not really to accuse man's nature; for the desires and passions are in themselves no sin, nor the actions proceeding from them, until a law is made against them. He seeks further evidence of an original condition of war, in the actual state of American savages, with no government at all, but only a concord of small families, depending on natural lust; also in the known horrors of a civil war, when there is no common power to fear: and, finally, in the constant hostile attitude of different governments.
In the state of natural war, the notions of right and wrong, justice and injustice, have no place, there being no law; and there is no law, because there is no common power. Force and fraud are in war the two cardinal virtues. Justice is no faculty of body and mind like sense and passion, but only a quality relating to men in society. Then adding a last touch to the description of the state of nature,—by saying of property, that 'only that is every man's that he can get, and for so long as he can keep it,'—he opens up, at the close of the chapter, a new prospect by allowing a possibility to come out of so evil a condition. The possibility consists partly in the passions that incline to peace—viz., fear of death, desire of things necessary to commodious living, and hope by industry to obtain them; partly in reason, which suggests convenient articles of peace and agreement, otherwise called the Laws of Nature.
The first and second Natural Laws, and the subject of contracts, take up Chap. XIV. First comes a definition of Jus Naturale or Right of Nature—the liberty each man has of using his own power, as he will himself, for the preservation of his own nature or life. Liberty properly means the absence of external impediments; now a man may externally be hindered from doing all he would, but not from using what power is left him, according to his best reason and judgment. A Law of Nature, lex naturalis is defined, a general rule, found out by reason, forbidding a man to do what directly or indirectly is destructive of his life, or to omit what he thinks may best preserve it. Right and Law, though generally confounded, are exactly opposed, Right being liberty, and Law obligation.
In the natural state of war, every man, being governed by his own reason, has a right to everything, even to another's body. But because thus no man's life is secure, he finds the First and fundamental law of nature, or general rule of reason, to be to seek peace and follow it, if possible: failing which, we may defend ourselves by all the means we can. Here the law being 'to endeavour peace,' from this follows the Second law, that a man be willing, when others are so too, as far forth as for peace and self-defence he shall think it necessary, to lay down this right to all things; and be contented with so much liberty against other men as he would allow other men against himself. This is the same as the Gospel precept, Do to others, &c.
