We thus see that the true essence of philosophy was there. Comte got a gratification by dissecting, analyzing and classifying his emotions. All was grist that came to his mill. When he was twenty-eight the Positive Philosophy had assumed such proportions in his mind that he announced a course of twelve lectures on the subject. He was jealous of his discoveries, and was intent on getting all the credit that was due him. Money he cared little for; power and reputation to him were the only gods worth appeasing. The thought of domestic joy was forever behind, but philosophy came as a solace. A prospectus was sent out and tickets were issued. The landlady where he boarded offered her parlor and her boarder, second floor back, for the benefit of science. Several zealous denizens of the Latin Quarter made a canvass, and enough tickets were sold so that the philosopher felt that at last the world was really at his feet. When the afternoon for the first lecture arrived, no carriages blocked the street, and as only about half of those who had purchased tickets appeared, the difficulties of the landlady and her nervous boarder were much lessened. There was one man at this first lecture who was profoundly impressed, and if we had his testimony, and none other, we might well restrain our smiles. That man was Alexander von Humboldt. In various passages Humboldt does Comte the honor of quoting from him, and in one instance says, "He has summed up certain phases of truth better than they have ever been expressed before." Little did the landlady guess that her crusty, crabbed boarder was firing a shot that would be heard 'round the world, and surely the gendarme on that particular beat never heard it--so small and commonplace are the beginnings of great things! Comte was so saturated with this theme--so immersed in it--that it consumed him like a fever. Three lectures were given, but at the third, without warning, the man's nerves snapped--he stopped, sat down, and the audience filed out perplexed, thinking they had merely seen an exhibition of one of the eccentricities of genius. The philosopher's mind was a blank, and kind friends sent him away to a hospital. It was two years before he regained his reason. The enforced rest did him good. Nervous Prostration is heroic treatment on the part of Nature. It is an intent to do for the man what he will never do for himself. * * * * * Unkind critics, hotly intent on refuting the Positive Philosophy, seized upon the fact of Comte's mental trouble and made much of it. "Look you!" said they, "the man is insane!"
