9. The fourth precept of nature is, _that every man render himself useful unto others_: which that we may rightly understand, we must remember that there is in men a diversity of dispositions to enter into society, arising from the diversity of their affections, not unlike that which is found in stones, brought together in the building, by reason of the diversity of their matter and figure. For as a stone, which in regard of its sharp and angular form takes up more room from other stones than it fills up itself, neither because of the hardness of its matter can it well be pressed together, or easily cut, and would hinder the building from being fitly compacted, is cast away, as not fit for use: so a man, for the harshness of his disposition in retaining superfluities for himself, and detaining of necessaries from others, and being incorrigible by reason of the stubbornness of his affections, is commonly said to be useless and troublesome unto others. Now, because each one not by right only, but even by natural necessity, is supposed with all his main might to intend the procurement of those things which are necessary to his own preservation; if any man will contend on the other side for superfluities, by his default there will arise a war; because that on him alone there lay no necessity of contending; he therefore acts against the fundamental law of nature. Whence it follows, (which we were to show), that it is a precept of nature, that every man accommodate himself to others. But he who breaks this law may be called _useless_ and troublesome. Yet Cicero opposeth _inhumanity_ to this _usefulness_, as having regard to this very law. [Sidenote: The fifth law of nature, of mercifulness.] 10. The fifth precept of the law of nature is, _that we must forgive him who repents and asks pardon for what is past, having first taken caution for the time to come_. The pardon of what is past, or the remission of an offence, is nothing else but the granting of peace to him that asketh it, after he hath warred against us, and now is become penitent. But peace granted to him that repents not, that is, to him that retains a hostile mind, or that gives not caution for the future, that is, seeks not peace, but opportunity; is not properly peace, but fear, and therefore is not commanded by nature. Now to him that will not pardon the penitent and that gives future caution, peace itself it seems is not pleasing: which is contrary to the natural law.
