VIII. Wherefore to return to our former intent of discovering the natural way, whereby rules have been found out concerning that goodness wherewith the Will of man ought to be moved in human actions; as every thing naturally and necessarily doth desire the utmost good and greatest perfection whereof Nature hath made it capable, even so man. Our felicity therefore being the object and accomplishment of our desire, we cannot choose but wish and covet it. All particular things which are subject unto action, the Will doth so far forth incline unto, as Reason judgeth them the better for us, and consequently the more available to our bliss. If Reason err, we fall into evil, and are so far forth deprived of the general perfection we seek. Seeing therefore that for the framing of men’s actions the knowledge of good from evil is necessary, it only resteth that we search how this may be had. Neither must we suppose that there needeth one rule to know the good and another the evil by1. For he that knoweth what is straight doth even thereby discern what is crooked, because the absence of straightness in bodies capable thereof is crookedness. Goodness in actions is like unto straightness; wherefore that which is done well we term right. For as the straight way is most acceptable to him that travelleth, because by it he cometh soonest to his journey’s end; so in action, that which doth lie the evenest between us and the end we desire must needs be the fittest for our use. Besides which fitness for use, there is also in rectitude, beauty; as contrariwise in obliquity, deformity. And that which is good in the actions of men, doth not only delight as profitable, but as amiable also. In which consideration the Grecians most divinely have given to the active perfection of men a name expressing both beauty and goodness2, because goodness in ordinary speech is for the most part applied only to that which is beneficial. But we in the name of goodness do here imply both.
And of discerning goodness there are but these two ways; the one the knowledge of the causes whereby it is made such; the other the observation of those signs and tokens, which being annexed always unto goodness, argue that where they are found, there also goodness is, although we know not the cause by force whereof it is there. The former of these is the most sure and infallible way, but so hard that all shun it, and had rather walk as men do in the dark by haphazard, than tread so long and intricate mazes for knowledge’ sake. As therefore physicians are many times forced to leave such methods of curing as themselves know to be the fittest, and being overruled by their patients’ impatiency are fain to try the best they can, in taking that way of cure which the cured will yield unto; in like sort, considering how the case doth stand with this present age full of tongue and weak of brain, behold we yield to the stream thereof; into the causes of goodness we will not make any curious or deep inquiry; to touch them now and then it shall be sufficient, when they are so near at hand that easily they may be conceived without any far-removed discourse: that way we are contented to prove, which being the worse in itself, is notwithstanding now by reason of common imbecility the fitter and likelier to be brooked3.
Signs and tokens to know good by are of sundry kinds; some more certain and some less. The most certain token of evident goodness is, if the general persuasion of all men do so account it. And therefore a common received error is never utterly overthrown, till such time as we go from signs unto causes, and shew some manifest root or fountain thereof common unto all, whereby it may clearly appear how it hath come to pass that so many have been overseen. In which case surmises and slight probabilities will not serve, because the universal consent of men is the perfectest and strongest in this kind, which comprehendeth only the signs and tokens of goodness. Things casual do vary, and that which a man doth but chance to think well of cannot still have the like hap. Wherefore although we know not the cause, yet thus much we may know; that some necessary cause there is, whensoever the judgments of all men generally or for the most part run one and the same way, especially in matters of natural discourse. For of things necessarily and naturally done there is no more affirmed but this, “They keep either always or for the most part one tenure4.” The general and perpetual voice of men is as the sentence of God himself5. For that which all men have at all times learned, Nature herself must needs have taught6; and God being the author of Nature, her voice is but his instrument. By her from Him we receive whatsoever in such sort we learn. Infinite duties there are, the goodness whereof is by this rule sufficiently manifested, although we had no other warrant besides to approve them. The Apostle St. Paul having speech concerning the heathen saith of them7, “They are a law unto themselves.” His meaning is, that by force of the light of Reason, wherewith God illuminateth every one which cometh into the world, men being enabled to know truth from falsehood, and good from evil, do thereby learn in many things what the will of God is; which will himself not revealing by any extraordinary means unto them, but they by natural discourse attaining the knowledge thereof, seem the makers of those Laws which indeed are his, and they but only the finders of them out.
