9. As a man's judgment, in right of nature, is to be employed for his own benefit, so also the strength, knowledge, and art of every man is then rightly employed, when he useth it for himself; else must not a man have right to preserve himself.
10. Every man by nature hath right to all things, that is to say, to do whatsoever he listeth to whom he listeth, to possess, use, and enjoy all things he will and can. For seeing all things he willeth, must therefore be good unto him in his own judgment, because he willeth them; and may tend to his preservation some time or other; or he may judge so, and we have made him judge thereof, sect. 8: it followeth that all things may rightly also be done by him. And for this cause it is rightly said: Natura dedit omnia omnibus, that Nature hath given all things to all men; insomuch, that jus and utile, right and profit, is the same thing. But that right of all men to all things, is in effect no better than if no man had right to any thing. For there is little use and benefit of the right a man hath, when another as strong, or stronger than himself, hath right to the same.
11. Seeing then to the offensiveness of man's nature one to another, there is added a right of every man to every thing, whereby one man invadeth with right, and another with right resisteth; and men live thereby in perpetual diffidence, and study how to preoccupate each other; the estate of men in this natural liberty is the estate of war. For WAR is nothing else but that time wherein the will and intention of contending by force is either by words or actions sufficiently declared; and the time which is not war is PEACE.
12. The estate of hostility and war being such, as thereby nature itself is destroyed, and men kill one another (as we know also that it is, both by the experience of savage nations that live at this day, and by the histories of our ancestors, the old inhabitants of Germany and other now civil countries, where we find the people few and short lived, and without the ornaments and comforts of life, which by peace and society are usually invented and procured): he therefore that desireth to live in such an estate, as is the estate of liberty and right of all to all, contradicteth himself. For every man by natural necessity desireth his own good, to which this estate is contrary, wherein we suppose contention between men by nature equal, and able to destroy one another.
13. Seeing this right of protecting ourselves by our own discretion and force, proceedeth from danger, and that danger from the equality between men's forces: much more reason is there, that a man prevent such equality before the danger cometh, and before there be necessity of battle. A man therefore that hath another man in his power to rule or govern, to do good to, or harm, hath right, by the advantage of this his present power, to take caution at his pleasure, for his security against that other in the time to come. He therefore that hath already subdued his adversary, or gotten into his power any other that either by infancy, or weakness, is unable to resist him, by right of nature may take the best caution, that such infant, or such feeble and subdued person can give him, of being ruled and governed by him for the time to come. For seeing we intend always our own safety and preservation, we manifestly contradict that our intention, if we willingly dismiss such a one, and suffer him at once to gather strength and be our enemy. Out of which may also be collected, that irresistible might in the state of nature is right.
14. But since it is supposed from the equality of strength and other natural faculties of men, that no man is of might sufficient, to assure himself for any long time, of preserving himself thereby, whilst he remaineth in the state of hostility and war; reason therefore dictateth to every man for his own good, to seek after peace, as far forth as there is hope to attain the same; and to strengthen himself with all the help he can procure, for his own defence against those, from whom such peace cannot be obtained; and to do all those things which necessarily conduce thereunto.
