But God having made Men so as that they find in themselves, very often, a liberty of acting according to the preference of their own Minds, it is incumbent upon them to study the Will of their Maker; in an application of the Faculty of Reason which he has given them, to the consideration of the different respects, consequences, and dependencies of Things, so as to discern from thence, the just measures of their actions in every circumstance and relation they stand plac'd in; which _measures_ are nothing else but the dictates resulting from those views which such a consideration of things as this gives us, of what is consonant, or not so, to the design of the Creator in every particular, wherein we are concern'd to act. And these manifestations of his Will, thus discoverable to us, ought to be regarded by us, as his Commands. Yet however certain it is, that the dictates of _Reason_, or _Nature_, discernable by our natural Faculties, are the commands of God to us, as rational Creatures; it is equally true that the love of happiness (which consists in pleasure) is the earliest, and strongest principle of Humane Nature; and therefore whatever measures Reason does, or might, prescribe, when particular occasions occur, the sentiment of what Men find pleasing or displeasing to them, however contrary to those dictates of right Reason, is very apt to determine their choice. God yet who is the Author of Order, and not of Confusion, has fram'd all things with Consistency, and Harmony; and however, in Fact, it too often happens that we are misled by that strong desire of happiness implanted in us, yet does this no way necessarily interfere with our acting in an intire conformity to the prescriptions of the Law of Reason; but the contrary: For from hence it is that this Law has its Sanction, _viz._ That, duly considering it, we shall evidently find our happiness, and misery, are annex'd to the observance, or neglect, of that unalterable Rule of Rectitude, discoverable to us by the Nature of Things; so that this Rule of Rectitude, or Eternal Will of God, has also the force of a Law given to it by that inseparable accord that there is betwixt our happiness or misery, with our obedience, or disobedience, hereunto. Thus our duty and happiness, can never be divided, but when we prefer a less happiness to a greater; and therein act not conformably to the dictates of our natural desire of happiness, or pleasure; which two Terms differ only in this, that we apply the Term _Pleasure_ to any agreeable Sentiment, or Sensation, how small, or short soever in its duration; but that of _Happiness_, only to such degrees of pleasure, as do, in some considerable degree, out-ballance our Evils.
