But his work bore the stamp of the struggle that was going on in that noble Spirit between the two great principles of Spiritualism and Materialism, round which so many a fine genius has beaten its way without ever daring to amalgamate them. Louis, at first purely Spiritualist, had been irresistibly led to recognize the Material conditions of Mind. Confounded by the facts of analysis at the moment when his heart still gazed with yearning at the clouds which floated in Swedenborg's heaven, he had not yet acquired the necessary powers to produce a coherent system, compactly cast in a piece, as it were. Hence certain inconsistencies that have left their stamp even on the sketch here given of his first attempts. Still, incomplete as his work may have been, was it not the rough copy of a science of which he would have investigated the secrets at a later time, have secured the foundations, have examined, deduced, and connected the logical sequence? Six months after the confiscation of the _Treatise on the Will_ I left school. Our parting was unexpected. My mother, alarmed by a feverish attack which for some months I had been unable to shake off, while my inactive life induced symptoms of _coma_, carried me off at four or five hours' notice. The announcement of my departure reduced Lambert to dreadful dejection. "Shall I ever seen you again?" said he in his gentle voice, as he clasped me in his arms. "You will live," he went on, "but I shall die. If I can, I will come back to you." Only the young can utter such words with the accent of conviction that gives them the impressiveness of prophecy, of a pledge, leaving a terror of its fulfilment. For a long time indeed I vaguely looked for the promised apparition. Even now there are days of depression, of doubt, alarm, and loneliness, when I am forced to repel the intrusion of that sad parting, though it was not fated to be the last. When I crossed the yard by which we left, Lambert was at one of the refectory windows to see me pass. By my request my mother obtained leave for him to dine with us at the inn, and in the evening I escorted him back to the fatal gate of the college. No lover and his mistress ever shed more tears at parting. "Well, good-bye; I shall be left alone in this desert!" said he, pointing to the playground where two hundred boys were disporting themselves and shouting. "When I come back half dead with fatigue from my long excursions through the fields of thought, on whose heart can I rest? I could tell you everything in a look. Who will understand me now?--Good-bye! I could wish I had never met you; I should not know all I am losing." "And what is to become of me?" said I. "Is not my position a dreadful one? _I_ have nothing here to uphold me!" and I slapped my forehead. He shook his head with a gentle gesture, gracious and sad, and we parted.
