We must further consider, that philosophers, who cultivate reason and reflection, stand less in need of such motives to keep them under the restraint of morals; and that the vulgar, who alone may need them, are utterly incapable of so pure a religion as represents the Deity to be pleased with nothing but virtue in human behaviour. The recommendations to the Divinity are generally supposed to be either frivolous observances, or rapturous ecstasies, or a bigoted credulity. We need not run back into antiquity, or wander into remote regions, to find instances of this degeneracy. Amongst ourselves, some have been guilty of that atrociousness, unknown to the Egyptian and Grecian superstitions, of declaiming in express terms, against morality; and representing it as a sure forfeiture of the Divine favour, if the least trust or reliance be laid upon it.
But even though superstition or enthusiasm should not put itself in direct opposition to morality; the very diverting of the attention, the raising up a new and frivolous species of merit, the preposterous distribution which it makes of praise and blame, must have the most pernicious consequences, and weaken extremely men's attachment to the natural motives of justice and humanity.
Such a principle of action likewise, not being any of the familiar motives of human conduct, acts only by intervals on the temper; and must be roused by continual efforts, in order to render the pious zealot satisfied with his own conduct, and make him fulfil his devotional task. Many religious exercises are entered into with seeming fervour, where the heart, at the time, feels cold and languid: A habit of dissimulation is by degrees contracted; and fraud and falsehood become the predominant principle. Hence the reason of that vulgar observation, that the highest zeal in religion and the deepest hypocrisy, so far from being inconsistent, are often or commonly united in the same individual character.
The bad effects of such habits, even in common life, are easily imagined; but where the interests of religion are concerned, no morality can be forcible enough to bind the enthusiastic zealot. The sacredness of the cause sanctifies every measure which can be made use of to promote it.
The steady attention alone to so important an interest as that of eternal salvation, is apt to extinguish the benevolent affections, and beget a narrow, contracted selfishness. And when such a temper is encouraged, it easily eludes all the general precepts of charity and benevolence.
Thus, the motives of vulgar superstition have no great influence on general conduct; nor is their operation favourable to morality, in the instances where they predominate.
Is there any maxim in politics more certain and infallible, than that both the number and authority of priests should be confined within very narrow limits; and that the civil magistrate ought, for ever, to keep his fasces and axes from such dangerous hands? But if the spirit of popular religion were so salutary to society, a contrary maxim ought to prevail. The greater number of priests, and their greater authority and riches, will always augment the religious spirit. And though the priests have the guidance of this spirit, why may we not expect a superior sanctity of life, and greater benevolence and moderation, from persons who are set apart for religion, who are continually inculcating it upon others, and who must themselves imbibe a greater share of it? Whence comes it then, that, in fact, the utmost a wise magistrate can propose with regard to popular religions, is, as far as possible, to make a saving game of it, and to prevent their pernicious consequences with regard to society? Every expedient which he tries for so humble a purpose is surrounded with inconveniences. If he admits only one religion among his subjects, he must sacrifice, to an uncertain prospect of tranquillity, every consideration of public liberty, science, reason, industry, and even his own independency. If he gives indulgence to several sects, which is the wiser maxim, he must preserve a very philosophical indifference to all of them, and carefully restrain the pretensions of the prevailing sect; otherwise he can expect nothing but endless disputes, quarrels, factions, persecutions, and civil commotions.
True religion, I allow, has no such pernicious consequences: but we must treat of religion, as it has commonly been found in the world; nor have I any thing to do with that speculative tenet of Theism, which, as it is a species of philosophy, must partake of the beneficial influence of that principle, and at the same time must lie under a like inconvenience, of being always confined to very few persons.
Oaths are requisite in all courts of judicature; but it is a question whether their authority arises from any popular religion. It is the solemnity and importance of the occasion, the regard to reputation, and the reflecting on the general interests of society, which are the chief restraints upon mankind. Custom-house oaths and political oaths are but little regarded even by some who pretend to principles of honesty and religion; and a Quaker's asseveration is with us justly put upon the same footing with the oath of any other person. I know, that POLYBIUS [Lib. vi. cap. 54.] ascribes the infamy of GREEK faith to the prevalency of the EPICUREAN philosophy: but I know also, that Punic faith had as bad a reputation in ancient times as Irish evidence has in modern; though we cannot account for these vulgar observations by the same reason. Not to mention that Greek faith was infamous before the rise of the Epicurean philosophy; and EURIPIDES [Iphigenia in Tauride], in a passage which I shall point out to you, has glanced a remarkable stroke of satire against his nation, with regard to this circumstance.
Take care, PHILO, replied CLEANTHES, take care: push not matters too far: allow not your zeal against false religion to undermine your veneration for the true. Forfeit not this principle, the chief, the only great comfort in life; and our principal support amidst all the attacks of adverse fortune. The most agreeable reflection, which it is possible for human imagination to suggest, is that of genuine Theism, which represents us as the workmanship of a Being perfectly good, wise, and powerful; who created us for happiness; and who, having implanted in us immeasurable desires of good, will prolong our existence to all eternity, and will transfer us into an infinite variety of scenes, in order to satisfy those desires, and render our felicity complete and durable. Next to such a Being himself (if the comparison be allowed), the happiest lot which we can imagine, is that of being under his guardianship and protection.
