Then, instinctively becoming physiological, he remarked on the resemblance to certain animals stamped on some human faces, accounting for them by primordial analogies and the upward tendency of all creation. He showed his audience the workings of Nature, and assigned a mission and a future to minerals, plants, and animals. Bible in hand, after thus spiritualizing Matter and materializing Spirit, after pointing to the Will of God in all things, and enjoining respect for His smallest works, he suggested the possibility of rising by faith from sphere to sphere. This was the first portion of his discourse, and by adroit digressions he applied the doctrine of his system to feudalism. The poetry--religious and profane--and the abrupt eloquence of that period had a grand opening in this vast theory, wherein the Doctor had amalgamated all the philosophical systems of the ancients, and from which he brought them out again classified, transfigured, purified. The false dogmas of two adverse principles and of Pantheism were demolished at his word, which proclaimed the Divine Unity, while ascribing to God and His angels the knowledge, the ends to which the means shone resplendent to the eyes of man. Fortified by the demonstrations that proved the existence of the world of Matter, Doctor Sigier constructed the scheme of a spiritual world dividing us from God by an ascending scale of spheres, just as the plant is divided from man by an infinite number of grades. He peopled the heavens, the stars, the planets, the sun. Quoting Saint Paul, he invested man with a new power; he might rise, from globe to globe, to the very Fount of eternal life. Jacob’s mystical ladder was both the religious formula and the traditional proof of the fact. He soared through space, carrying with him the passionate souls of his hearers on the wings of his word, making them feel the infinite, and bathing them in the heavenly sea. Then the Doctor accounted logically for hell by circles placed in inverse order to the shining spheres that lead to God, in which torments and darkness take the place of the Spirit and of light. Pain was as intelligible as rapture. The terms of comparison were present in the conditions of human life and its various atmospheres of suffering and of intellect. Thus the most extraordinary traditions of hell and purgatory were quite naturally conceivable.
