From whence it follows, that were the publique and private interest are most closely united, there is the publique most advanced.

The RIGHT OF NATURE, which Writers commonly call Jus Naturale, is the Liberty each man hath, to use his own power, as he will himself, for the preservation of his own Nature; that is to say, of his own Life; and consequently, of doing any thing, which in his own Judgement, and Reason, he shall conceive to be the aptest means thereunto.

Whatsoever therefore is consequent to a time of Warre, where every man is Enemy to every man; the same is consequent to the time, wherein men live without other security, than what their own strength, and their own invention shall furnish them withall. In such condition, there is no place for Industry; because the fruit thereof is uncertain: and consequently no Culture of the Earth; no Navigation, nor use of the commodities that may be imported by Sea; no commodious Building; no Instruments of moving, and removing things as require much force; no Knowledge of the face of the Earth; no account of Time; no Arts; no Letters; no Society; and which is worst of all, continuall feare, and danger of violent death; And the life of man solitary, poore, nasty, brutish, and short.

For Warre, consisteth not in Battell onely, or the act of fighting; but in a tract of time, wherein the Will to contend by Battell is sufficiently known: and therefore the notion of Time, is to be considered in the nature of Warre; as it is in the nature of Weather.

Hereby it is manifest, that during the time men live without a common Power to keep them all in awe, they are in that conditions called Warre; and such a warre, as is of every man, against every man.

For such is the nature of men, that howsoever they may acknowledge many others to be more witty, or more eloquent, or more learned; Yet they will hardly believe there be many so wise as themselves: For they see their own wit at hand, and other men's at a distance.

For Prudence, is but Experience; which equal time, equally bestows on all men, in those things they equally apply themselves unto.

And in these foure things, Opinion of Ghosts, Ignorance of second causes, Devotion towards what men fear, and Taking of things Casuall for Prognostics, consisteth the Natural seed of Religion; which by reason of the different Fancies, Judgements, and Passions of severall men, hath grown up into ceremonies so different, that those which are used by one man, are for the most part ridiculous to another.

The doctrine of Right and Wrong, is perpetually disputed, both by Pen and the Sword: Whereas the doctrine of Lines, and Figures, is not so; because men care not, in that subject what be truth, as a thing that crosses no mans ambition, profit, or lust. For I doubt not, but if it had been a thing contrary to any mans right of dominion, or to the interest of men that have dominion, That the three Angles of a Triangle, should be equall to two Angles of a Square; that doctrine should have been, if not disputed, yet by the burning of all books of Geometry, suppressed, as far as he whom it concerned was able.

And because the condition of Man, (as hath been declared in the precedent Chapter) is a condition of Warre of every one against everyone; in which case every one is governed by his own Reason; and there is nothing he can make use of, that may not be a help unto him, in preserving his life against his enemyes; It followeth, that in such a condition, every man has a Right to every thing; even to one anothers body.

That a man be willing, when others are so too, as farre-forth, as for Peace, and defence of himself 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.

As first a man cannot lay down the right of resisting them, that assault him by force, to take away his life; because he cannot be understood to ayme thereby, at any Good to himself.

As in the presence of the Master, the Servants are equall, and without any honour at all; So are the Subjects, in the presence of the Soveraign. And though they shine some more, some lesse, when they are out of his sight; yet in his presence, they shine no more than the Starres in presence of the Sun.

"I Authorize and give up my Right of Governing my selfe, to this Man, or to his Assembly of men, on this condition, that thou that give up thy Right to him, and Authorise all his Actionsin like manner." This done, the Multitude so united in one Person, is called a COMMON-WEALTH, in latine CIVITAS. This is the Generation of that LEVIATHAN, or rather (to speake more reverently) of that Mortall God, to which we owe under the Immortal God, our peace and defence.

For the Lawes of Nature (as Justice, Equity, Modesty, Mercy, and (in summe)doing to others, as wee would be done to,) of themselves, without the terrour of some Power, to cause them to be observed, are contrary to our naturall Passions, that carry us to Partiality, Pride, Revenge, and the like. And Covenants, without the Sword, are but Words, and of no strength to secure a man at all.

And the Science of them, is the true and onely Moral Philosophy. For Moral Philosophy is nothing else but the Science of what is Good, and Evill, in the conversation, and Society of mankind. Good, and Evill, are names that signify our Appetites, and Aversions; which in different tempers, customes, and doctrines of men, are different:

And though this may seem to subtile a deduction of the Lawes of Nature, to be taken notice of by all men;whereof the most part are too busie in getting food, and the rest too negligent to understand; yet to leave all men unexcusable, they have been contracted into one easie sum, intelligble, even to the meanest capacity; and that is, Do not that to another, which thou wouldest not have done to thyselfe; which sheweth him, that he has no more to do in learning the Lawes of Nature, but, when weighing the actions of other men with his own, they seem too heavy, to put them into the other part of the balance, and his own into their place, that his own passions, and selfe love, may adde nothing to the weight; and then there is none of these Laws of Nature that will not appear unto him very reasonable.

"And seeing every man is presumed to do all things in order to his own benefit, no man is a fit Arbitrator in his own cause:"

Men looke not at the greatnesse of the evill past, but the greatnesse of the good to follow.

A Covenant not to defend my selfe from force, by force, is always voyd.

From the same it proceedeth,that men gives different names, to one and the same thing, from the difference of their own passions: As they that approve a private opinion, call it Opinion; but they that mislike it, Haeresie: and yet haeresie signifies no more than private opinion; but has only agreater tincture of choler

So that in the first place, I put for a general inclination of all mankind a perpetual and restless desire of Power after power, that ceaseth only in Death. And the cause of this is not always that a man hopes for a more intensive delight than he has already attained to, or that he cannot be content with a moderate power: but because he cannot assure the power and means to live well, which he hath present, without the acquisition of more.

Desire, to know why, and how, CURIOSITY; such as is in no living creature but Man; so that Man is distinguished, not only by his Reason; but also by this singular Passion from other Animals; in whom the appetite of food, and other pleasures of Sense, by predominance, take away the care of knowing causes; which is a Lust of the mind, that by a perseverance of delight in the continual and indefatigable generation of Knowledge, exceedeth the short vehemence of any carnal Pleasure.

The same, without such opinion, DESPAIRE.

For Appetite with an opinion of attaining, is called HOPE.

But Aversion wee have for things, not only which we know have hurt us; but also that we do not know whether they will hurt us, or not.

But yet they that have no Science, are in better, and nobler condition with their naturall Prudence; than men, that by their mis-reasoning, or by trusting them that reason wrong, fall upon false and absurd generall rules.

Science is the knowledge of Consequences, and dependence of one fact upon another: by which, out of that we can presently do, we know how to do something else when we will, or the like, another time:

It is not easy to fall into any absurdity, unless it be by the length of an account; wherein he may perhaps forget what went before. For all men by nature reason alike, and well, when they have good principles. For who is so stupid as both to mistake in geometry, and also to persist in it, when another detects his error to him? By this it appears that reason is not, as sense and memory, born with us; nor gotten by experience only, as prudence is; but attained by industry: first in apt imposing of names; and secondly by getting a good and orderly method in proceeding from the elements, which are names, to assertions made by connexion of one of them to another; and so to syllogisms, which are the connexions of one assertion to another, till we come to a knowledge of all the consequences of names appertaining to the subject in hand; and that is it, men call science. And whereas sense and memory are but knowledge of fact, which is a thing past and irrevocable, science is the knowledge of consequences, and dependence of one fact upon another; by which, out of that we can presently do, we know how to do something else when we will, or the like, another time: because when we see how anything comes about, upon what causes, and by what manner; when the like causes come into our power, we see how to make it produce the like effects. Children therefore are not endued with reason at all, till they have attained the use of speech, but are called reasonable creatures for the possibility apparent of having the use of reason in time to come.

The first cause of Absurd conclusions I ascribe to the want of Method; in that they begin not their Ratiocination from Definitions; that is, from settled significations of their words: as if they could cast account, without knowing the value of the numerall words, one, two, and three.

Sudden Glory, is the passion which maketh those Grimaces called LAUGHTER.

And Beasts that have Deliberation, must necessarily also have Will.

For there is no such thing as perpetual Tranquility of mind, while we live here; because Life it selfe is but Motion, and can never be without Desire, nor without Feare, no more than without Sense.

Felicity is a continual progress of the desire from one object to another, the attaining of the former being still but the way to the latter.The cause whereof is that the object of man's desire is not to enjoy once only, and for one instant of time, but to assure forever the way of his future desire. And therefore the voluntary actions and inclinations of all men tend not only to the procuring, but also to the assuring of a contented life, and differ only in the way, which ariseth partly from the diversity of passions in diverse men, and partly from the difference of the knowledge or opinion each one has of the causes which produce the effect desired.

By MANNERS, I mean not here Decency of behaviour; as how one man should salute another, or how a man should wash his mouth, or pick his teeth before company, and such other points of the Small Morals; But those qualities of mankind that concern their living together in Peace and Unity. To which end we are to consider that the Felicity of this life consisteth not in the repose of a mind satisfied. For there is no such Finis ultimus (utmost aim) nor Summum Bonum (greatest good) as is spoken of in the books of the old Moral Philosophers. Nor can a man any more live whose desires are at an end than he whose Senses and Imaginations are at a stand.

And as in other things, so in men, not the seller, but the buyer determines the Price.

The Value or WORTH of a man, is as of all other things, his Price; that is to say, so much as would be given for the use of his Power...

The Register of Knowledge of Fact is called History.

The secret thoughts of a man run over all things, holy, prophane, clean, obscene, grave, and light, without shame, or blame…

When two, or more men, know of one and the same fact, they are said to be CONSCIOUS of it one to another; which is as much as to know it together.

Of all Discourse, governed by desire of Knowledge, there is at last an End, either by attaining, or by giving over.

But this priviledge, is allayed by another; and that is, by the priviledge of Absurdity; to which no living creature is subject, but man only.

At the age of forty he was, for the first time, introduced to the works of Euclid, and at once 'fell in love with geometry,' being attracted, he says, more by the rigorous manner of proof employed than by the matter of the science. (Mathematics... were then only beginning to be seriously studied in England. Hobbes tells us that in his undergraduate days geometry was still looked upon generally as a form of the 'Black Art,' and it was not until 1619 that the will of Sir Henry Savile, Warden of Merton College, established the first Professorships of Geometry and Astronomy at Oxford.)

There are several passages in Hobbes's translation of Homer, which, if they had been writ on purpose to ridicule that poet, would have done very well.

Although longer experience may have lent some older members of these bands some authority, it was mainly shared aims and perceptions that coordinated the activities of their members. These modes of coordination depended decisively on instincts of solidarity and altruism - instincts applying to the members of one's own group but not to others. The members of these small groups could thus exist only as such: an isolated man would soon have been a dead man. The primitive individualism described by Thomas Hobbes is hence a myth. The savage is not solitary, and his instinct is collectivist. There was never a 'war of all against all'.

Thomas Hobbes was the first sociobiologist, two hundred years before Darwin.

Our current conception of mathematics as an ideal science, of geometry in particular as dealing with an ideal space, rather than the actual space in which the universe is set, was a notion quite unformulated before Hobbes, and not taken seriously till the middle of the eighteenth century, though it was dimly felt after by a few Aristotelian opponents of Copernicus.

The thoughts are to the desires, as scouts and spies, to range abroad and find the way to the thing desired.

For such Truth as opposeth no man's profit nor pleasure is to all men welcome.

But if it bee well considered, The praise of Ancient Authors, proceeds not from the reverence of the Dead, but from the competition and mutual envy of the Living.
