"Such was the first and necessary origin of every idea of the divinity...."
"In reality, when the vulgar heard others talk of a new heaven and another world, they gave a body to these fictions; they erected on it a solid stage and real scenes; and their notions of geography and astronomy served to strengthen, if they did not give rise to the delusion.
"On the one hand, the Phoenician navigators, those who passed the pillars of Hercules to fetch the pewter of Thule and the amber of the Baltic, related that at the extremity of the world, the boundaries of the ocean (the Mediterranean,) where the sun sets to the countries of Asia, there were Fortunate Islands, the abode of an everlasting spring; and at a farther distance, hyperborean regions, placed under the earth (relatively to the tropics,) where reigned an eternal night. From those stories, badly understood, and no doubt confusedly related, the imagination of the people composed the Elysian Fields, delightful spots in a world below, having their heaven, their sun, and their stars; and Tartarus, a place of darkness, humidity, mire, and chilling frost. Now, inasmuch as mankind, inquisitive about all that of which they are ignorant, and desirous of a protracted existence, had already exerted their faculties respecting what was to become of them after death; inasmuch, as they had early reasoned upon that principle of life which animates the body, and which quits it without changing the form of the body, and had conceived to themselves airy substances, phantoms and shades, they loved to believe that they should resume in the subterranean world that life which it was so painful to lose; and this abode appeared commodious for the reception of those beloved objects which they could not prevail on themselves to renounce.
"On the other hand, the astrological and philosophical priests told such stories of their heavens as perfectly quadrated with these fictions. Having, in their metaphorical language, denominated the equinoxes and solstices the gates of heaven, or the entrance of the seasons, they explained the terrestrial phenomena by saying, that through the gate of horn (first the bull, afterwards the ram,) vivifying fires descended, which, in spring, gave life to vegetation, and aquatic spirits, which caused, at the solstice, the overflowing of the Nile: that through the gate of ivory (originally the bowman, or Sagittarius, then the balance,) and through that of Capricorn, or the urn, the emanations or influences of the heavens returned to their source and re-ascended to their origin; and the Milky Way which passed through the doors of the solstices, seemed to them to have been placed there on purpose to be their road and vehicle. The celestial scene farther presented, according to their Atlas, a river (the Nile, designated by the windings of the Hydra;) together with a barge (the vessel Argo,) and the dog Sirius, both bearing relation to that river, of which they foreboded the overflowing. These circumstances, added to the preceding ones, increased the probability of the fiction; and thus to arrive at Tartarus or Elysium, souls were obliged to cross the rivers Styx and Acheron, in the boat of Charon the ferryman, and to pass through the doors of horn and ivory, which were guarded by the mastiff Cerberus. At length a civil usage was joined to all these inventions, and gave them consistency.
"The inhabitants of Egypt having remarked that the putrefaction of dead bodies became in their burning climate the source of pestilence and diseases, the custom was introduced in a great number of States, of burying the dead at a distance from the inhabited districts, in the desert which lies at the West. To arrive there it was necessary to cross the canals of the river in a boat, and to pay a toll to the ferryman, otherwise the body remaining unburied, would have been left a prey to wild beasts. This custom suggested to her civil and religious legislators, a powerful means of affecting the manners of her inhabitants, and addressing savage and uncultivated men with the motives of filial piety and reverence for the dead; they introduced, as a necessary condition, the undergoing that previous trial which should decide whether the deceased deserved to be admitted upon the footing of his family honors into the black city. Such an idea too well accorded with the rest of the business not to be incorporated with it; it accordingly entered for an article into religious creeds, and hell had its Minos and its Radamanthus, with the wand, the chair, the guards, and the urn, after the exact model of this civil transaction. The divinity then, for the first time, became a subject of moral and political consideration, a legislator, by so much the more formidable as, while his judgment was final and his decrees without appeal, he was unapproachable to his subjects. This mythological and fabulous creation, composed as it was of scattered and discordant parts, then became a source of future punishments and rewards, in which divine justice was supposed to correct the vices and errors of this transitory state. A spiritual and mystical system, such as I have mentioned, acquired so much the more credit as it applied itself to the mind by every argument suited to it. The oppressed looked thither for an indemnification, and entertained the consoling hope of vengeance; the oppressor expected by the costliness of his offerings to secure to himself impunity, and at the same time employed this principle to inspire the vulgar with timidity; kings and priests, the heads of the people, saw in it a new source of power, as they reserved to themselves the privilege of awarding the favors or the censure of the great Judge of all, accord-ing to the opinion they, should inculcate of the odiousness of crimes and the meritoriousness of virtue.
"Thus, then, an invisible and imaginary world entered into competition with that which was real. Such, O Persians! was the origin of your renovated earth, your city of resurrection, placed under the equator, and distinguished from all other cities by this singular attribute, that the bodies of its inhabitants cast no shade. Such, O Jews and Christians! disciples of the Persians, was the source of your New Jerusalem, your paradise and your heaven, modelled upon the astrological heaven of Hermes. Meanwhile your hell, O ye Musselmans! a subterraneous pit surmounted by a bridge, your balance of souls and good works, your judgment pronounced by the angels Monkir and Nekir, derives its attributes from the mysterious ceremonies of the cave of Mithra; and your heaven is exactly coincident with that of Osiris, Ormuzd, and Brama."....
"It is evident, that it is not truth for which you contend; that it is not her cause you are jealous of maintaining, but the cause of your own passions and prejudices; that it is not the object as it really exists that you wish to verify, but the object as it appears to you; that it is not the evidence of the thing that you are anxious should prevail, but your personal opinion, your mode of seeing and judging. There is a power that you want to exercise, an interest that you want to maintain, a prerogative that you want to assume: in short, the whole is a struggle of vanity. And as every individual, when he compares himself with every other, finds himself to be his equal and fellow, he resists by a similar feeling of right; and from this right, which you all deny to each other, and from the inherent consciousness of your equality, spring your disputes, your combats, and your intolerance.
"Now the only way of restoring unanimity is by returning to nature, and taking the order of things which she has established for your director and guide, and this farther truth will then appear from your uniformity of sentiment.
"If we would arrive at uniformity of opinion, we must previously establish certainty, and verify the resemblance which our ideas have to their models. Now, this cannot be obtained, except so far as the objects of our inquiry can be referred to the testimony, and subjected to the examination of our senses. Whatever cannot be brought to this trial is beyond the limits of our understanding: we have neither rule to try it by, nor measure by which to institute a comparison, nor source of demonstration and knowledge concerning it.
"Whence it is obvious that, in order to live in peace and harmony, we must consent not to pronounce upon such objects, nor annex to them importance; we must draw a line of demarcation between such as can be verified and such as cannot, and separate, by an inviolable barrier, the world of fantastic beings from the world of realities: that is to say, all civil effect must be taken away from theological and religious opinions.
