5. Moreover, considering that many men’s appetites carry them to one and the same end; which end sometimes can neither be enjoyed in common, nor divided, it followeth, that the stronger must enjoy it alone, and that it be decided by battle who is the stronger. And thus the greatest part of men, upon no assurance of odds, do nevertheless, through vanity, or comparison, or appetite, provoke the rest, that otherwise would be contented with equality. [Sidenote: Right defined.] 6. And forasmuch as necessity of nature maketh men to will and desire _bonum sibi_, that which is good for themselves, and to avoid that which is hurtful; but most of all, the terrible enemy of nature, death, from whom we expect both the loss of all power, and also the greatest of bodily pains in the losing; it is not against reason, that a man doth all he can to preserve his own body and limbs both from death and pain. And that which is not against reason, men call _right_, or _jus_, or _blameless liberty_ of using our own natural power and ability. It is therefore a right of nature, that every man may preserve his own life and limbs, with all the power he hath. [Sidenote: Right to the end, implieth right to the means.] 7. And because where a man hath right to the end, and the end cannot be attained without the means, that is, without such things as are necessary to the end, it is consequent that it is not against reason, and therefore right, for a man to use all means, and do whatsoever action is necessary for the preservation of his body. [Sidenote: Every man his own judge by nature.] 8. Also, every man by right of nature, is judge himself of the necessity of the means, and of the greatness of the danger. For if it be against reason, that I be judge of mine own danger myself, then it is reason, that another man be judge thereof. But the same reason that maketh another man judge of those things that concern me, maketh me also judge of that that concerneth him. And therefore I have reason to judge of his sentence, whether it be for my benefit, or not. [Sidenote: Every man’s strength and knowledge for his own use.] 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. [Sidenote: Every man by nature hath right to all things.]
