THE INTRODUCTION


The Design of this Treatise.

Two ways of deducing the Laws of Nature.1. From their Effects.

This insisted on by Grotius, Sharrock, &c.

§I. It concerns us both, friendly Reader, “That you should be briefly acquainted with the Design and Method of this Treatise”; for thence you will immedately perceive, “What I have perform’d, or, at least, attempted; and what is further to be supply’d from your own Understanding, or the Writings of others.” The Laws of Nature are the Foundations of all moral and civil Knowledge, as in the following Work will at large appear. But these, as all other Conclusions, discoverable by the Light of Nature, may be deduc’d two ways; either from those manifest Effects which flow from them, or from the Causes whence they themselves arise. I have endeavour’d to discover them in this latter Method, by arguing from the Cause to the Effect. To the former Method of proving their Obligation, (by arguing from the Effect to the Cause,) belongs what has been written by Hugo Grotius, and by his Brother, in his Posthumous Work, and by our Countryman Sharrock, who establish them from the approv’d Sentiments of various Authors of different Nations and Ages, as also from a Harmony in the Manners and Laws, if not of all, at least of the politer, Nations.1 Hitherto also is to be referr’d that Work of Selden’s, concerning the Laws of Nature and Nations, according to the Sentiments of the Hebrews.2 And, in my Opinion, all these Authors have deserv’d well of Mankind. But especially the Work of Hugo Grotius, which was the first of the kind, I think worthy, both of the Author, and of Immortality. For a few Slips, and those in Matters, in which the Customs of his Country seem to have biass’d that great Man, will easily obtain Pardon from a candid Reader.

Useful, tho objected against.

§II. Nor, truly, are the Objections, which are usually brought against this method of proving the Laws of Nature, (by arguing from the Effect to the Cause, as Grotius does,) of so great weight, as to prove it altogether fallacious and useless; altho I readily acknowledge, that they may so far prevail with candid Inquirers after Truth, as to convince them, That it would be more useful and safe, to find out a fuller Proof, by searching into the Causes, which produce in the Mind of Man the Knowledge of the Laws of Nature. This, however, will more plainly appear, if we briefly propose those Objections, with the Answers to them.

First Objection from insufficient Induction.

In the first place it is objected, “That the Induction is weak, which infers, from the Writings or Manners of a few Men, or Nations, the Opinion or Judgment of all.” Now there is scarce any Person so well acquainted with the Laws and Customs of any one State, that can ever have a perfect Knowledge of them all; much less that can attain to such a Knowledge of the Laws of all States, still less, of the inward Sentiments of each Individual, as may enable him, upon a just Comparison, to conclude, what those Notions are, in which all agree.

To this it is answer’d, “That the Judgments made by different Nations concerning matters of daily publick Practice, (such are Religion, or some sort of divine Worship in general, and a degree of Humanity, sufficient to prohibit Murder, Theft, and Adultery,) may with ease be every where observ’d by any Man, without so profound a Knowledge of their Laws”: and such Judgments sufficiently declare that they agree in the Laws of Nature; for that which we know by Experience, to be, as it were, naturally acknowledg’d good by many Nations, we presume, upon account of the likeness of human Nature, to be likewise acknowledg’d good by the rest; especially when our Adversaries cannot produce one undoubted Instance, to prove any Nation to be of different Sentiments. To me, truly, those Narratives of some few barbarous Americans, and the Hottentots, “That they have no religious Worship,” seem, not suspected only but, false; for such a negative Assertion is hardly capable of ever being prov’d by Testimony. Therefore Acosta3 and some others seem rashly to have form’d a Judgment concerning those, with whose Language, Manners, and Sentiments they could not thorowly acquaint themselves in so short a time. For we read, that both Jews and Christians were sometimes falsly accus’d by many, of the greatest Impieties, tho their Religion was more holy than that of other Nations. But, be that as it will, it is manifest, “That those Truths are with sufficient Clearness propos’d to all, which are readily acknowledg’d by almost every one, altho the same should be either overlook’d, or even oppos’d, by some few.” But this Observation will be the most proper, and of greatest use, when it appears manifestly from other Proofs than Testimony and Custom, “That these Propositions teach the true Means to the best End, and that all are indispensably oblig’d to pursue that End by those Means”; which may be best prov’d by a consideration of the Causes, which suggest such conclusions of Reason to our Minds.

Obj. 2. That they want a sufficient enacting Authority.

§III. A second Objection is, “That, altho certain Conclusions of Reason are approv’d of by our own Judgment, and the Practice of many others, yet the Authority of a known Law-giver is wanting, to give them the force of Laws to all Men; for otherwise,” (say they,) “who ever holds them in contempt, has the same Right to reject the Judgment of any others whomsoever, that they exercise in condemning his Opinion by their Words and Actions.” To this purpose, both Hobbes and Selden object, (beside the Antients,) but with very different Views.4

According to Hobbes,

For, as we shall shew in the following Treatise, the Point Mr. Hobbes aims at, is, “That none should believe themselves oblig’d by the Conclusions of Reason, with respect to their outward Actions, before a civil Magistrate is appointed; and that all his Appointments should be look’d upon, as the perfectly obligatory Judgments of right Reason.” It is to this purpose that he affirms, that “The Laws of Nature, altho they are laid down in the Writings of Philosophers, are no more, for that Reason, to be look’d upon as written Laws, than the Opinions of Lawyers are Laws, and that for want of a sovereign Authority.”5 He would not indeed deny them the Name of Laws, which he had before vouchsafed to give them, (tho improperly, as he elsewhere confesses;)6 he was willing however to insinuate, that they were not promulg’d by a sufficient Authority, tho Philosophers learn them from the Nature of Things, and thence transcribe them into their Writings. It is nevertheless manifest, if they be already truly Laws made by the Author of Nature, that they need no new Authority, after they are set down in writing by any one, to make them become written Laws.

And Selden, but with different Virtues.

But Mr. Selden denies, “That the Conclusions of Reason, consider’d barely in themselves, have the Authority of Laws,” upon no other account, than, in order to shew “the Necessity of having recourse to the Legislative Power of God, and of proving that God has commanded our Obedience to them, and, by making them known to us, has proclaim’d them his Laws.” And indeed he has judiciously, as far as I can judge, given this Hint to the moral Philosophers, who are wont to consider the Conclusions of their own Reason as Laws, without due Proof, that they have the necessary Form of a Law, or that they are establish’d by God. But when he is to shew the Manner wherein God might manifest to Mankind, these to be his Laws, he proposes two ways.7 1. That God himself pronounc’d them with his sacred Voice to Adam and Noah, in joining them perpetual Obedience; whence these Precepts of the Sons of Noah were handed down to all their Posterity by Tradition only. 2. That God has endow’d rational Minds with a Faculty able, by Application of their Understanding, to discover those Laws, and to distinguish them, when discover’d, from all positive Institutions.

Not sufficiently answer’d by the latter.

He only transiently hints, in such general Terms, this latter Method, which however to me seems to want much Explanation and Proof; but he betakes himself wholly to the former, and endeavours to prove, from the Traditions of some Jewish Rabbins, “That God gave seven Precepts to the Sons of Noah, in the observance whereof all Justice amongst Men should consist.” And truly he has abundantly prov’d,8 “That the Jews thought that all Nations, altho they did not receive the Laws of Moses, were nevertheless oblig’d by some divine Laws, whose chief Heads they look’d upon the Precepts of the Sons of Noah to be.” And this proves at least, “That, in the Opinion of that Nation, which was not inconsiderable either for Numbers or Learning, there are Laws, not made by any State, that bind all Mankind.” It is likewise to be own’d, that this learned Man chiefly aim’d at this Point, and that with good Success; and that the Knowledge of this Matter is of considerable use in Christian Divinity. Selden, however, has not sufficiently answer’d his own Objection, which we before mention’d. For, altho these Jewish Traditions were thorowly known, and perhaps firmly believ’d, by him,9 they were not however manifested to all Mankind; and those things which that Nation looks upon as the greatest Mysteries of Religion, are by many ridicul’d. And to me truly it seems self-evident, “That an unwritten Tradition of the learned Men of one Nation, is not a sufficient Promulgation of a Law of Nature, which is to oblige all Nations.”

To answer this Objection, the Author chuses the second Method of deducing the Laws of Nature from their Causes, by their divine-Promulgation and Sanction.

§IV. Wherefore, that the Conclusions of Reason in moral Matters might more evidently appear to be Laws, Laws of God, I have thought it proper to make a philosophical Inquiry into their Causes, as well Internal as External, the nearer and the more remote; for by this Method we shall at last arrive at their first Author, or efficient Cause, from whose essential Perfections, and internal Sanction of them by Rewards and Punishments,10 we have shewn that their Authority arises. Most others have been satisfy’d with saying in general Terms, “That these Conclusions, or Actions conformable to them, are taught by Nature”; but to me it seems necessary, especially at this time, to trace more distinctly, after what manner the Powers of things, as well without as within us, conspire to imprint these Conclusions upon our Minds, and to give a Sanction to them. Our Countryman, the Lord Verulam, has reckon’d such an Inquiry among the things which are wanting.11 This, if solidly perform’d, will therefore be of very great use; because thence will appear, both how our Mind is, by the Light of Nature, let into the Knowledge of the Will or Laws of God, so as that it cannot be free from the warning of Conscience; and what that Rule is, whereby the Justice and Rectitude of the Laws of particular States is to be measured, and their Injustice and Imperfection to be corrected and amended by the supreme Authority if they have at any time deviated from the best and greatest End. Hence also, (that it may appear, that Morality is not the Artifice of Ecclesiastics or Politicians,) is further shewn, “That there is something in the Nature of God, of other Men, and of our selves, which in good Actions affords present Comfort and Joy, and a well-grounded Expectation of future Rewards.” On the other hand, “That there are Causes which must naturally produce the most violent Grief and Fear, after evil Actions; so that the Sentence of Conscience may be justly look’d upon as armed with Scourges against Impiety.”12

Without insisting on innate Ideas of them.

§V. The Platonists, indeed, clear up this Difficulty in an easier manner, by the Supposition of innate Ideas, as well of the Laws of Nature themselves, as of those Matters about which they are conversant; but, truly, I have not been so happy as to learn the Laws of Nature in so short a way.13 Nor seems it to me well advised, to build the Doctrine of natural Religion and Morality upon an Hypothesis, which has been rejected by the generality of Philosophers, as well Heathen as Christian, and can never be prov’d against the Epicureans, with whom is our chief Controversy. I was resolv’d, however, not to oppose this Opinion, because it is my earnest desire, that whatever looks with a friendly Aspect upon Piety and Morality, might have its due weight; (and I look upon these Platonists to be favourers of their Cause;) and because it is not impossible, that such Ideas might be both born with us, and afterwards impress’d upon us from without.

Or supposing, without Proof, their eternal Existence in the divine Mind.

Their Promulgation and Obligation, and eternal Existence in, or agreeableness to, the divine Mind, prov’d.

§VI. Moreover, the same Reasons, which hinder’d us from supposing innate Ideas of the Laws of Nature in our Minds, hinder us likewise from supposing, without Proof, that these Laws have existed from Eternity in the divine Mind. I have therefore thought it necessary to remove the Difficulty, and assert and prove the Authority and eternal Existence of these Conclusions in the divine Mind, in the following Method; assuming those Notices which we have from Sense and daily Experience, I demonstrate, “That the Nature of things, which subsists, and is continually govern’d, by its first Cause, does necessarily imprint on our Minds some practical Propositions, (which must be always true, and cannot without a Contradiction be suppos’d otherwise,) concerning the Study of promoting the joint Felicity of all Rationals: And that the Terms of these Propositions do immediately and directly signify, that the first Cause, in his original Constitution of Things, has annex’d the greatest Rewards and Punishments to the observance and neglect of these Truths.” Whence it manifestly follows, “That they are Laws,” Laws being nothing but practical Propositions, with Rewards and Punishments annex’d, promulg’d by competent Authority. Having hence shewn, “That the Knowledge and Practice of these Laws, is the natural Perfection or most happy State of our rational Nature,” I infer, “That there must be in the first Cause, (from whom proceed both this our Perfection, and that most wise Disposition which we see, every Day, of Effects without us, for the common Preservation and Perfection of the whole System,) a Perfection correspondent, but infinitely superior, to this Knowledge and Practice of the Laws of Nature.” For I look upon it as most evident, “That we must first know what Justice is, and from whence those Laws are deriv’d, in the observance whereof it wholly consists, before we can distinctly know, that Justice is to be attributed to God, and that we ought to propose his Justice as our Example.” For we come not at the Knowledge of God by immediate Intuition of his Perfections, but from his Effects14 first known by Sense and Experience; nor can we safely ascribe to him Attributes, which from other Considerations we do not sufficiently comprehend.

The chief Heads of the following Book.

The Effects of corporeal Motions, Effects of the divine Will.

§VII. Having hitherto shewn, in general, the Difference between our Method and that of others, I think it proper, to shew briefly here the chief things which are more at large and dispersedly deliver’d in the following Discourse. Having undertaken only, “to deliver the Precepts of moral Philosophy, and to deduce them from some little Knowledge of Nature presuppos’d”; what natural Philosophers, especially those who reason upon mathematical Principles, have often demonstrated, I assume, as sufficiently prov’d. But my principal Supposition is, “That all Effects of corporeal Motions, which are necessary, according to the common Course of Nature, and depend not upon the Will of Man, are produc’d by the Will of the first Cause”: for this comes to no more than saying, “That all Motions are begun by the Impression of a first Mover, and are by the same Impression continued, and perpetually determin’d, according to certain Laws.” For I thought it superfluous to prove that which had been already prov’d by most natural Philosophers, and is plainly acknowledg’d by Hobbes himself, whose Doctrine I am now examining. Leviath. Chap. 12. After he has assign’d the Cause of Religion, among Men, to their anxious Concern about Futurity, he adds thus, (whether insidiously or no, let others judge;) “The acknowledging of one God Eternal, Infinite and Omnipotent, may more easily be deriv’d from the Desire Men have to know the Causes of natural Bodies, and their several Virtues and Operations, than from the fear of what was to befal them in time to come: for he that from any Effect he seeth come to pass, should reason to the next and immediate Cause thereof, and from thence to the Cause of that Cause, and plunge himself profoundly in the pursuit of Causes; shall at last come to this, that there must be (as even the Heathen Philosophers confess’d) one first Mover; that is, a first and eternal Cause of all things, which is that which Men mean by the Name of God.”15 But if it be granted, “That every natural Effect points out God as its Author,” no Man can deny, “That all such Effects are determin’d by his Will,” unless he is inconsistent
