But being come of age and finding it necessary to turn his mind to something more marketable than abstract speculation, he determined, though apparently without any natural inclination toward the art, to become a painter. He apprenticed himself to his brother John Hazlitt, who had gained some reputation in London for his miniatures. During the peace of Amiens in 1802, he travelled to the Louvre to study and copy the masterpieces which Napoleon had brought over from Italy as trophies of war. Here, as he "marched delighted through a quarter of a mile of the proudest efforts of the mind of man, a whole creation of genius, a universe of art,"[6] he imbibed a love of perfection which may have been fatal to his hopes of a career. At any rate it was soon after, while he was following the profession of itinerant painter through England, that he wrote to his father of "much dissatisfaction and much sorrow," of "that repeated disappointment and that long dejection which have served to overcast and to throw into deep obscurity some of the best years of my life."[7] When Hazlitt abandoned painting, he fell back upon his analytic gift as a means of earning a living. Not counting his first published work, the Essay on the Principles of Human Action, which was purely a labor of love and fell still-born from the press, the tasks to which he now devoted his time were chiefly of the kind ordinarily rated as job work. He prepared an abridgement of Abraham Tucker's Light of Nature, compiled the Eloquence of the British Senate, wrote a reply to Malthus's Essay on Population, and even composed an elementary English Grammar. It would be a mistake to suppose that these labors were performed according to a system of mechanical routine. Hazlitt impressed something of his personality on whatever he touched. His violent attack on the inhuman tendencies of Malthus's doctrines is pervaded by a glow of humanitarian indignation. For the Eloquence of the British Senate he wrote a sketch of Burke, which for fervor of appreciation and judicious analysis ranks with his best things of this class. Even the Grammar bears evidence of his enthusiasm for an idea. Whenever he has occasion to express his feelings on a subject of popular interest, his manner begins to grow animated and his language to gain in force and suppleness. But Hazlitt continued firmly in the faith that it was his destiny to be a metaphysician. In 1812 he undertook to deliver a course of lectures on philosophy at the Russell Institution with the ambitious purpose of founding a system of philosophy "more conformable to reason and experience" than that of the modern material school which resolved "all thought into sensation, all morality into the love of pleasure, and all action into mechanical impulse."[8] Though he did not succeed in founding a system, he probably interested his audience by a stimulating review of the main tendencies of English thought from Bacon and Hobbes to Priestley and Godwin.
