51. The elements of spiritual revelation having been given simultaneously at a multitude of points to men of all social conditions and of different degrees of knowledge, it is very evident that observations could not have been made everywhere with the same effect; that the sequences drawn from them, the relation of the laws which govern this order of phenomena, - in a word, the conclusion which ought to establish ideas, - could proceed only from the harmony and correlation of facts. Now, every isolated center, circumscribed in a limited circle, seeing most often only a particular order of manifestations, sometimes in appearance contradictory, having communications generally with the same category of spirits, and, moreover, blocked by the local influences and by the spirit of party, finds it materially impossible to embrace the whole, powerless to join isolated observations to a common principle. Each one judging facts according to his knowledge and his anterior beliefs, or by the particular opinions of the spirits manifesting, there would soon be as many theories and systems as centers, of which no one would be complete, in default of elements of comparison and of control. In a word, each one would remain content with his partial revelation, believing it to include all the truth, for want of knowledge that in a hundred other places one could obtain more or better.
