If man was subjected to an absolute monarch, to a sultan who should keep himself secluded from his subjects; who followed no rule but his own desires; who did not feel himself bound by any duty; who could for ever punish the offences committed against him; whose fury it was easy to provoke; who was irritated even by the ideas, the thoughts of his subjects; whose displeasure might be incurred without even their own knowledge; the name of such a sovereign would assuredly be sufficient to carry trouble, to spread terror, to diffuse consternation into the very souls of those who should hear it pronounced; his idea would haunt them every where--would unceasingly afflict them--would plunge them into despair. What tortures would not their mind endure to discover this formidable being, to ascertain the secret of pleasing him! What labour would not their imagination bestow, to discover what mode of conduct might be able to disarm his anger! What fears would assail them, lest they might not have justly hit upon the means of assuaging his wrath! What disputes would they not enter into upon the nature, the qualities of a ruler, equally unknown to them all! What a variety of means would not be adopted, to find favour in his eyes; to avert his chastisement!

Such is the history of the effects superstition has produced upon the earth. Man has always been panic-struck, because the systems adopted never enable him to form any correct opinion, any fixed ideas, upon a subject so material to his happiness; because every thing conspired either to give his ideas a fallacious turn, or else to keep his mind in the most profound ignorance; when he was willing to set himself right, when he was sedulous to examine the path which conducted to his felicity, when he was desirous of probing opinions so consequential to his peace, involving so much mystery, yet combining both his hopes and his fears, he was forbidden to employ the only proper method,--HIS REASON, guided by his experience; he was assured this would be an offence the most indelible. If he asked, Wherefore his reason had then been given him, since he was not to use it in matters of such high behest? he was answered, those were mysteries of which none but the initiated could be informed; that it sufficed for him to know, that the reason which he seemed so highly to prize, which he held in so much esteem, was his most dangerous enemy--his most inveterate, most determined foe. Where can be the propriety of such an argument? Can it really be that reason is dangerous? If so, the Turks are justified in their predilection for madmen: but to proceed, he is told that he must believe in the gods, not question the mission of their priests; in short, that he had nothing to do with the laws they imposed, but to obey them: when he then required that these laws might at least be made comprehensible to him; that he might be placed in a capacity to understand them; the old answer was returned, that they were _mysteries_; he must not inquire into them. But where is the necessity for mystery in points of such vast importance? He might, indeed, from time to time consult these oracles, when he was able to make the sacrifices demanded; he would then receive precepts for his conduct: these were always, however, given in such vague, indeterminate terms, that he had scarcely the chance of acting right. At different times the same oracles delivered different opinions: thus he had nothing, steady; nothing permanent, whereby to guide his steps; like a blind man left to himself in the streets, he was obliged to grope his way at the peril of his existence. This will serve to shew the urgent necessity there is for truth to throw its radiant lustre on systems big with so much importance; that are so calculated to corroborate the animosities, to confirm the bitterness of soul, between those whom nature intended should always act as brothers.
