But when we look beyond human affairs and the properties of the surrounding bodies: when we carry our speculations into the two eternities, before and after the present state of things; into the creation and formation of the universe; the existence and properties of spirits; the powers and operations of one universal Spirit existing without beginning and without end; omnipotent, omniscient, immutable, infinite, and incomprehensible: We must be far removed from the smallest tendency to scepticism not to be apprehensive, that we have here got quite beyond the reach of our faculties. So long as we confine our speculations to trade, or morals, or politics, or criticism, we make appeals, every moment, to common sense and experience, which strengthen our philosophical conclusions, and remove, at least in part, the suspicion which we so justly entertain with regard to every reasoning that is very subtle and refined. But, in theological reasonings, we have not this advantage; while, at the same time, we are employed upon objects, which, we must be sensible, are too large for our grasp, and of all others, require most to be familiarised to our apprehension. We are like foreigners in a strange country, to whom every thing must seem suspicious, and who are in danger every moment of transgressing against the laws and customs of the people with whom they live and converse. We know not how far we ought to trust our vulgar methods of reasoning in such a subject; since, even in common life, and in that province which is peculiarly appropriated to them, we cannot account for them, and are entirely guided by a kind of instinct or necessity in employing them.

All sceptics pretend, that, if reason be considered in an abstract view, it furnishes invincible arguments against itself; and that we could never retain any conviction or assurance, on any subject, were not the sceptical reasonings so refined and subtle, that they are not able to counterpoise the more solid and more natural arguments derived from the senses and experience. But it is evident, whenever our arguments lose this advantage, and run wide of common life, that the most refined scepticism comes to be upon a footing with them, and is able to oppose and counterbalance them. The one has no more weight than the other. The mind must remain in suspense between them; and it is that very suspense or balance, which is the triumph of scepticism.

But I observe, says CLEANTHES, with regard to you, PHILO, and all speculative sceptics, that your doctrine and practice are as much at variance in the most abstruse points of theory as in the conduct of common life. Wherever evidence discovers itself, you adhere to it, notwithstanding your pretended scepticism; and I can observe, too, some of your sect to be as decisive as those who make greater professions of certainty and assurance. In reality, would not a man be ridiculous, who pretended to reject NEWTON's explication of the wonderful phenomenon of the rainbow, because that explication gives a minute anatomy of the rays of light; a subject, forsooth, too refined for human comprehension? And what would you say to one, who, having nothing particular to object to the arguments of COPERNICUS and GALILEO for the motion of the earth, should withhold his assent, on that general principle, that these subjects were too magnificent and remote to be explained by the narrow and fallacious reason of mankind?

There is indeed a kind of brutish and ignorant scepticism, as you well observed, which gives the vulgar a general prejudice against what they do not easily understand, and makes them reject every principle which requires elaborate reasoning to prove and establish it. This species of scepticism is fatal to knowledge, not to religion; since we find, that those who make greatest profession of it, give often their assent, not only to the great truths of Theism and natural theology, but even to the most absurd tenets which a traditional superstition has recommended to them. They firmly believe in witches, though they will not believe nor attend to the most simple proposition of Euclid. But the refined and philosophical sceptics fall into an inconsistence of an opposite nature. They push their researches into the most abstruse corners of science; and their assent attends them in every step, proportioned to the evidence which they meet with. They are even obliged to acknowledge, that the most abstruse and remote objects are those which are best explained by philosophy. Light is in reality anatomised. The true system of the heavenly bodies is discovered and ascertained. But the nourishment of bodies by food is still an inexplicable mystery. The cohesion of the parts of matter is still incomprehensible. These sceptics, therefore, are obliged, in every question, to consider each particular evidence apart, and proportion their assent to the precise degree of evidence which occurs. This is their practice in all natural, mathematical, moral, and political science. And why not the same, I ask, in the theological and religious? Why must conclusions of this nature be alone rejected on the general presumption of the insufficiency of human reason, without any particular discussion of the evidence? Is not such an unequal conduct a plain proof of prejudice and passion?

Our senses, you say, are fallacious; our understanding erroneous; our ideas, even of the most familiar objects, extension, duration, motion, full of absurdities and contradictions. You defy me to solve the difficulties, or reconcile the repugnancies which you discover in them. I have not capacity for so great an undertaking: I have not leisure for it: I perceive it to be superfluous. Your own conduct, in every circumstance, refutes your principles, and shows the firmest reliance on all the received maxims of science, morals, prudence, and behaviour.

I shall never assent to so harsh an opinion as that of a celebrated writer [L'Arte de penser], who says, that the Sceptics are not a sect of philosophers: They are only a sect of liars. I may, however, affirm (I hope without offence), that they are a sect of jesters or raillers. But for my part, whenever I find myself disposed to mirth and amusement, I shall certainly choose my entertainment of a less perplexing and abstruse nature. A comedy, a novel, or at most a history, seems a more natural recreation than such metaphysical subtleties and abstractions.

In vain would the sceptic make a distinction between science and common life, or between one science and another. The arguments employed in all, if just, are of a similar nature, and contain the same force and evidence. Or if there be any difference among them, the advantage lies entirely on the side of theology and natural religion. Many principles of mechanics are founded on very abstruse reasoning; yet no man who has any pretensions to science, even no speculative sceptic, pretends to entertain the least doubt with regard to them. The COPERNICAN system contains the most surprising paradox, and the most contrary to our natural conceptions, to appearances, and to our very senses: yet even monks and inquisitors are now constrained to withdraw their opposition to it. And shall PHILO, a man of so liberal a genius and extensive knowledge, entertain any general undistinguished scruples with regard to the religious hypothesis, which is founded on the simplest and most obvious arguments, and, unless it meets with artificial obstacles, has such easy access and admission into the mind of man?

And here we may observe, continued he, turning himself towards DEMEA, a pretty curious circumstance in the history of the sciences. After the union of philosophy with the popular religion, upon the first establishment of Christianity, nothing was more usual, among all religious teachers, than declamations against reason, against the senses, against every principle derived merely from human research and inquiry. All the topics of the ancient academics were adopted by the fathers; and thence propagated for several ages in every school and pulpit throughout Christendom. The Reformers embraced the same principles of reasoning, or rather declamation; and all panegyrics on the excellency of faith, were sure to be interlarded with some severe strokes of satire against natural reason. A celebrated prelate [Monsr. Huet] too, of the Romish communion, a man of the most extensive learning, who wrote a demonstration of Christianity, has also composed a treatise, which contains all the cavils of the boldest and most determined PYRRHONISM. LOCKE seems to have been the first Christian who ventured openly to assert, that faith was nothing but a species of reason; that religion was only a branch of philosophy; and that a chain of arguments, similar to that which established any truth in morals, politics, or physics, was always employed in discovering all the principles of theology, natural and revealed. The ill use which BAYLE and other libertines made of the philosophical scepticism of the fathers and first reformers, still further propagated the judicious sentiment of Mr. LOCKE: And it is now in a manner avowed, by all pretenders to reasoning and philosophy, that Atheist and Sceptic are almost synonymous. And as it is certain that no man is in earnest when he professes the latter principle, I would fain hope that there are as few who seriously maintain the former.
