"Since, however, these opinions, extraordinary as they may be, must have had some origin; since even the most abstract and fantastical ideas have some physical model, it may be useful to recur to this origin, and discover this model--in a word, to find out from what source the human understanding has drawn these ideas, at present so obscure, of God, of the soul, of all immaterial beings, which make the basis of so many systems; to unfold the filiation which they have followed, and the alterations which they have undergone in their transmissions and ramifications. If, then, there are any persons present who have made a study of these objects, let them come forward, and endeavor, in the face of nations, to dissipate the obscurity in which their opinions have so long remained." CHAPTER XXII. ORIGIN AND FILIATION OF RELIGIOUS IDEAS. At these words, a new group, formed in an instant by men from various standards, but not distinguished by any, came forward into the circle; and one of them spoke in the name of the whole: "Delegates, friends of evidence and virtue! It is not surprising that the subject in question should be enveloped in so many clouds, since, besides its inherent difficulties, thought itself has always been encumbered with superadded obstacles peculiar to this study, where all free enquiry and discussion have been interdicted by the intolerance of every system. But now that our views are permitted to expand, we will expose to open day, and submit to the judgment of nations, that which unprejudiced minds, after long researches, have found to be the most reasonable; and we do this, not with the pretension of imposing a new creed, but with the hope of provoking new lights, and obtaining better information. "Doctors and instructors of nations! You know what thick darkness covers the nature, the origin, the history of the dogmas which you teach. Imposed by authority, inculcated by education, and maintained by example, they pass from age to age, and strengthen their empire from habit and inattention. But if man, enlightened by reflection and experience, brings to mature examination the prejudices of his childhood, he soon discovers a multitude of incongruities and contradictions which awaken his sagacity and excite his reasoning powers. "At first, remarking the diversity and opposition of the creeds which divide the nations, he takes courage to question the infallibility which each of them claims, and arming himself with their reciprocal pretensions, he conceives that his senses and his reason, derived immediately from God, are a law not less holy, a guide not less sure, than the mediate and contradictory codes of the prophets.
