Hear the verbal protestations of all men: Nothing so certain as their religious tenets. Examine their lives: You will scarcely think that they repose the smallest confidence in them. The greatest and truest zeal gives us no security against hypocrisy: The most open impiety is attended with a secret dread and compunction. No theological absurdities so glaring that they have not, sometimes, been embraced by men of the greatest and most cultivated understanding. No religious precepts so rigorous that they have not been adopted by the most voluptuous and most abandoned of men. … Look out for a people, entirely destitute of religion: If you find, them at all, be assured, that they are but few degrees removed from brutes. What so pure as some of the morals, included in some theological system? What so corrupt as some of the practices, to which these systems give rise?
As every enquiry, which regards religion, is of the utmost importance, there are two questions in particular, which challenge our attention, to wit, that concerning its foundation in reason, and that concerning its origin in human nature. Happily, the first question, which is the most important, admits of the most obvious, at least, the clearest, solution. The whole frame of nature bespeaks an intelligent author; and no rational enquirer can, after serious reflection, suspend his belief a moment with regard to the primary principles of genuine Theism and Religion. But the other question, concerning the origin of religion in human nature, is exposed to some more difficulty. The belief of invisible, intelligent power has been very generally diffused over the human race, in all places and in all ages; but it has neither perhaps been so universal as to admit of no exception, nor has it been, in any degree, uniform in the ideas, which it has suggested. Some nations have been discovered, who entertained no sentiments of Religion, if travellers and historians may be credited; and no two nations, and scarce any two men, have ever agreed precisely in the same sentiments.
That original intelligence, say the Magians, who is the first principle of all things, discovers himself immediately to the mind and understanding alone; but has placed the sun as his image in the visible universe; and when that bright luminary diffuses its beams over the earth and the firmament, it is a faint copy of the glory which resides in the higher heavens. If you would escape the displeasure of this divine being, you must be careful never to set your bare foot upon the ground, nor spit into a fire, nor throw any water upon it, even though it were consuming a whole city. Who can express the perfections of the Almighty? say the Mahometans. Even the noblest of his works, if compared to him, are but dust and rubbish. How much more must human conception fall short of his infinite perfections? His smile and favour renders men for ever happy; and to obtain it for your children, the best method is to cut off from them, while infants, a little bit of skin, about half the breadth of a farthing. Take two bits of cloth, say the Roman catholics, about an inch or an inch and a half square, join them by the corners with two strings or pieces of tape about sixteen inches long, throw this over your head, and make one of the bits of cloth lie upon your breast, and the other upon your back, keeping them next your skin: There is not a better secret for recommending yourself to that infinite Being, who exists from eternity to eternity.
To oppose the torrent of scholastic religion by such feeble maxims as these, that it is impossible for the same thing to be and not to be, that the whole is greater than a part, that two and three make five; is pretending to stop the ocean with a bullrush. Will you set up profane reason against sacred mystery? No punishment is great enough for your impiety. And the same fires, which were kindled for heretics, will serve also for the destruction of philosophers. … The whole is a riddle, an aenigma, an inexplicable mystery. Doubt, uncertainty, suspence of judgment appear the only result of our most accurate scrutiny, concerning this subject. But such is the frailty of human reason, and such the irresistible contagion of opinion, that even this deliberate doubt could scarcely be upheld; did we not enlarge our view, and opposing one species of superstition to another, set them a quarreling; while we ourselves, during their fury and contention, happily make our escape, into the calm, though obscure, regions of philosophy.
We may observe, that, notwithstanding the dogmatical, imperious style of all superstition, the conviction of the religionists, in all ages, is more affected than real, and scarcely ever approaches, in any degree, to that solid belief and persuasion, which governs us in the common affairs of life. Men dare not avow, even to their own hearts, the doubts which they entertain on such subjects: They make a merit of implicit faith; and disguise to themselves their real infidelity, by the strongest asseverations and most positive bigotry. But nature is too hard for all their endeavours, and suffers not the obscure, glimmering light, afforded in those shadowy regions, to equal the strong impressions, made by common sense and by experience. The usual course of men’s conduct belies their words, and shows, that their assent in these matters is some unaccountable operation of the mind between disbelief and conviction, but approaching much nearer to the former than to the latter.
The universal propensity to believe in invisible, intelligent power, if not an original instinct, being at least a general attendant of human nature, may be considered as a kind of mark or stamp, which the divine workman has set upon his work; and nothing surely can more dignify mankind, than to be thus selected from all other parts of the creation, and to bear the image or impression of the universal Creator. But consult this image, as it appears in the popular religions of the world. How is the deity disfigured in our representations of him! What caprice, absurdity, and immorality are attributed to him! How much is he degraded even below the character, which we should naturally, in common life, ascribe to a man of sense and virtue!
The two greatest enemies of religion are infidelity and blind zeal, the former attacks it like an open enemy, and the latter, like an indiscreet friend, does it more harm than good. The first gives rise to the free thinkers, the latter to our sectaries. A truly religious life has the same efficacy to the prevention of both.
It might reasonably be expected in questions which have been canvassed and disputed with great eagerness, since the first origin of science and philosophy, that the meaning of all the terms, at least, should have been agreed upon among the disputants; and our enquiries, in the course of two thousand years, been able to pass from words to the true and real subject of the controversy. For how easy may it seem to give exact definitions of the terms employed in reasoning, and make these definitions, not the mere sound of words, the object of future scrutiny and examination? But if we consider the matter more narrowly, we shall be apt to draw a quite opposite conclusion. From this circumstance alone, that a controversy has been long kept on foot, and remains still undecided, we may presume that there is some ambiguity in the expression, and that the disputants affix different ideas to the terms employed in the controversy. For as the faculties of the mind are supposed to be naturally alike in every individual; otherwise nothing could be more fruitless than to reason or dispute together; it were impossible, if men affix the same ideas to their terms, that they could so long form different opinions of the same subject; especially when they communicate their views, and each party turn themselves on all sides, in search of arguments which may give them the victory over their antagonists. It is true, if men attempt the discussion of questions which lie entirely beyond the reach of human capacity, such as those concerning the origin of worlds, or the economy of the intellectual system or region of spirits, they may long beat the air in their fruitless contests, and never arrive at any determinate conclusion. But if the question regard any subject of common life and experience, nothing, one would think, could preserve the dispute so long undecided but some ambiguous expressions, which keep the antagonists still at a distance, and hinder them from grappling with each other.
[U]pon the whole, we may conclude that the Christian Religion not only was at first attended with miracles, but even at this day cannot be believed by any reasonable person without one…. Whoever is moved by Faith to assent to it, is conscious of a continued miracle in his own person, which subverts all the principles of his understanding, and gives him a determination to believe what is most contrary to custom and experience.
