Doctor Sigier was to-day to recapitulate, in the last of a series of discourses, the views he had set forth in the former lectures on the Resurrection, Heaven, and Hell. His strange doctrine responded to the sympathies of the time, and gratified the immoderate love of the marvelous, which haunts the mind of man in every age. This effort of man to clutch the infinite, which for ever slips through his ineffectual grasp, this last tourney of thought against thought, was a task worthy of an assembly where the brightest luminaries of the age had met, and where the most stupendous human imagination ever known, perhaps, at that moment shone.

The Doctor began by summing up in a mild and even tone the principal points he had so far established:

"No intellect was the exact counterpart of another. Had man any right to require an account of his Creator for the inequality of powers bestowed on each? Without attempting to penetrate rashly into the designs of God, ought we not to recognize the fact that by reason of their general diversity intelligences could be classed in spheres? From the sphere where the least degree of intelligence gleamed, to the most translucent souls who could see the road by which to ascend to God, was there not an ascending scale of spiritual gift? And did not spirits of the same sphere understand each other like brothers in soul, in flesh, in mind, and in feeling?"

From this the Doctor went on to unfold the most wonderful theories of sympathy. He set forth in Biblical language the phenomena of love, of instinctive repulsion, of strong affinities which transcend the laws of space, of the sudden mingling of souls which seem to recognize each other. With regard to the different degrees of strength of which our affections are capable, he accounted for them by the place, more or less near the centre, occupied by beings in their respective circles.

He gave mathematical expression to God's grand idea in the co-ordination of the various human spheres. "Through man," he said, "these spheres constituted a world intermediate between the intelligence of the brute and the intelligence of the angels." As he stated it, the divine Word nourishes the spiritual Word, the spiritual Word nourishes the living Word, the living Word nourishes the animal Word, the animal Word nourishes the vegetable Word, and the vegetable Word is the expression of the life of the barren Word. These successive evolutions, as of a chrysalis, which God thus wrought in our souls, this infusorial life, so to speak, communicated from each zone to the next, more vivid, more spiritual, more perceptive in its ascent, represented, rather dimly no doubt, but marvelously enough to his inexperienced hearers, the impulse given to Nature by the Almighty. Supported by many texts from the Sacred Scriptures, which he used as a commentary on his own statements to express by concrete images the abstract arguments he felt to be wanting, he flourished the Spirit of God like a torch over the deep secrets of creation, with an eloquence peculiar to himself, and accents that urged conviction on his audience. As he unfolded his mysterious system and all its consequences, he gave a key to every symbol and justified the vocation, the special gifts, the genius, the talent of each human being.

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 the 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.

He gave the fundamental rationale of virtue with admirable clearness. A pious man, toiling onward in poverty, proud of his good conscience, at peace with himself, and steadfastly true to himself in his heart in spite of the spectacle of exultant vice, was a fallen angel doing penance, who remembered his origin, foresaw his guerdon, accomplished his task, and obeyed his glorious mission. The sublime resignation of Christians was then seen in all its glory. He depicted martyrs at the burning stake, and almost stripped them of their merit by stripping them of their sufferings. He showed their inner angel as dwelling in the heavens, while the outer man was tortured by the executioner's sword. He described angels dwelling among men, and gave tokens by which to recognize them.

He next strove to drag from the very depths of man's understanding the real sense of the word fall, which occurs in every language. He appealed to the most widely-spread traditions in evidence of this one true origin, explaining, with much lucidity, the passion all men have for rising, mounting—an instinctive ambition, the perennial revelation of our destiny.
