Most of those who call’d themselves Philosophers, were never in earnest in their pretended Researches after Virtue; they made it matter of mere Ostentation, and to shew their Parts, and an Affair of as great Indifference, as Problems in Mathematicks, or Natural Philosophy; thinking it sufficient, if they could but amuse the Vulgar, and dispute learnedly about it; and accordingly in by far the greatest Number of those who affected to distinguish themselves by that glorious Title, it reach’d no farther than the Head, not to the Heart, as is plain from the profligate Manners of many of them from the Accounts of their Contemporaries. And how should Mankind be reform’d by such Instructors? They who were influenc’d by the Truth they taught appear, upon Examination, to be much fewer than is generally imagin’d. And even those very few, we have seen that they grossly err’d in most important Points, as well with respect to God, as the Cause and Cure of the present corrupt Condition of Mankind, and the End for which our great Creator intended us. No less Men among them than Plato, Cicero, and Epictetus advise Men to comply, each with the establish’d Religion of his Country; but was that the way to enlighten and reform a benighted and idolatrous World? The Wisest of them have profess’d their Ignorance, how the Deity was to be worshipp’d, and how those who had done amiss were to be reconcil’d to him; of which Plato represents Socrates so sensible, as to introduce him in one of his Dialogues, declaring his Ignorance upon these Heads, and wishing for the Guidance of a Divine Revelation in such Matters, for which our wiser modern Deists think there was no occasion. Those also among the Heathen Philosophers, who have upon some occasions argued the most strenuously for the Soul’s Immortality, sometimes express themselves doubtfully upon the Matter. ’Tis the Christian Religion only, which hath clearly brought Life and Immortality to Light. The refin’d Reasonings and long Deductions of acute and speculative Philosophers upon this and other important Points, the Attributes of God, and the Obligations to Virtue, were too fine-spun, and required too long and close an Application, to influence the generality of Mankind. None of them was able to form any thing like a tolerable Scheme with respect to Providence, the Forming and the Governing the World, the Dignity and the Corruption of human Nature, whence the Obligation to Virtue originally arises, and to what it ultimately tends, and the happy Immortality of the Righteous. All of them were Ignorant of some of these Truths, and the imperfect Truth they did discover, lies so scatered and blended with Error, that the greatest Genius among them was never able to collect them into one Body; and there is so strict a Dependence of one of these Truths upon another, that it is like breaking a Link in a Chain, or taking a Corner-Stone from the Foundation of a Building, to separate one of them from the rest; so close is their Connexion. What is more; whilst the Hearers of the Philosophers consider’d that these Instructors were but Men like themselves, the Truths they were able to discover and support by plain Reason, were able to make but a weak Impression upon them, for want of sufficient Weight, and because they were not enforc’d by a Divine Authority. It awakens and rouses the Attention and Consideration of Men at another sort of a rate, not only to have it laid before them, that such a Practice is agreeable to the Dictates of Right Reason, that it is Beautiful, Honourable, and Decorous, that we ought to do it, and that such Advantages will naturally and necessarily attend it; but also to have it clearly made out to ’em, that it is moreover the Will and positive Command of the Creator and supreme Governor of the World, to whom they owe what they are and what they have, and at whose hands they expect all they hope for; which makes a much deeper Impression upon them, than barely to have the fitness of the Practice propos’d to ’em, without the Interposition of the Authority of a competent Legislator, to whom they are under the greatest Obligations in point of Gratitude, and who will certainly vindicate the Honour of his Laws.
After all these Considerations, let any impartial Man judge, whether a Revelation was useful or necessary for the Reformation of Mankind. No, says the modern Deist; for the Light and Law of Nature, Natural Religion, and Morality are sufficient, as they have been laid down by Plato, Aristotle, Cicero, Epictetus, M. Antoninus, and others among the Antients; by Grotius, Puffendorf, Crellius, Sharrock, Wilkins, Cumberland, Clark, Wollaston, and others among the Moderns. In answer to this, I desire that it may be observ’d, That there is a great Difference between mere natural Reason, and Reason assisted by Revelation, and super natural Help. Our Reason assents to many Things, when propos’d to us, which it could never have found out. The greatest Genius’s among the Heathen Philosophers, seem to have been extremely sensible of the Weakness, the Short-sightedness, and the Uncertainty of their Reasonings about most important Truths. Let us hear what they themselves say upon the Point, “Nature gives many Indications of her Will; but we” (saith Cicero317) “are deaf, I know not how, nor hear her Voice.” “Nature hath afforded us some small Sparks, which we so quickly extinguish by evil Habits and false Opinions, that the Light of Nature no where appears.”318 “We seem not only blind with respect to Wisdom, but dull and stupid with respect to those very Things, which in some measure we seem to see.”319 “Our Minds” (saith Aristotle) “with respect to those Things which are naturally the most plain of all, are like the Eyes of Bats in Day-light.”320 “Truly” (saith Cicero) “the so great Dissention of the most learned Men in an Affair of the utmost Importance [the Nature of the Gods] will stagger even those, who before thought that they had arriv’d at Certainty in the Point.” And “I wish” (saith Cicero in the same Discourse) “that I could as easily find out the Truth, as confute Error.”321 Even Socrates express’d himself with doubt concerning a Future State, tho’ he seem’d strongly to incline to the Belief of it, and tho’ he brought the best Arguments in support of it, as they are represented to us by Plato, that we meet with offered by any Heathen Philosopher. Cicero, in his Tusculan Questions, is still more doubtful upon that Head, tho’ inclining to the same side with Socrates. Seneca look’d upon it as a point more desirable, than probable.322 “If (says Cicero323) in the Opinion of all Philosophers, no-one has attain’d Wisdom, we, for whose welfare you pretend the Immortal Gods have made the best Provision, are in a most wretched State; for, as there is no material Difference, whether no Man does enjoy his Health, or no Man can enjoy it; so I do not see that it is of any consequence, whether no Man is or can be made wise.” What wonder then is it, if the best and wisest of the Philosophers, thus sensible of their own Ignorance, and of the Weakness of human Reason, with respect to matters of the utmost Importance, (such as the Nature of the Deity, how he would be worshipp’d, and a future State; as also the Original of Evil, and of the present corrupt Condition of Mankind, of which they were as sensible, as they were ignorant of the Cause,) should be sensible of the Want of a Divine Revelation, and earnestly long for it, as has been already mention’d? Now, whoever would go about rationally to make a comparative Judgment of assisted and unassisted Reason, let him compare the Schemes of Natural Religion and of Morality, left us by the Heathens, with those which have been publish’d by Christians. Plato, Aristotle, Cicero, Plutarch, Epictetus, and M. Antoninus, are clearly the greatest Heathen Writers upon these Subjects. How defective these are all, I have already, in great measure, laid before the Reader, some of them making no more of Virtue and of Religion, than mere Civil and Political Institutions; all of them conforming to the Idolatrous Establishments of their several Countries, and advising others to do the like; Polytheism and the Worship of Demons being essential Parts of the Platonick and Stoick Theology, as Magick and the Worship of Demons were of the Pythagorean; and yet these have been reputed the best Sects, and to have produc’d the greatest Moral Philosophers, which Heathen Antiquity could boast of. I have already observ’d,
