HARTLEY, JONATHAN SCOTT (1845- ), American sculptor, was born at Albany, New York, on the 23rd of September 1845. He was a pupil of E. D. Palmer, New York, and of the schools of the Royal Academy, London; he later studied for a year in Berlin and for a year in Paris. His first important work (1882) was a statue of Miles Morgan, the Puritan, for Springfield, Mass. Among his other works are the Daguerre monument in Washington; “Thomas K. Beecher,” Elmira, New York, and “Alfred the Great,” Appellate Court House, New York. He devoted himself particularly to the making of portrait busts, in which he attained high rank. In 1891 he became a member of the National Academy of Design.
HARTLIB, SAMUEL (c. 1599-c. 1670), English writer on education and agriculturist, was born towards the close of the 16th century at Elbing in Prussia, his father being a refugee merchant from Poland. His mother was the daughter of a rich English merchant at Danzig. About 1628 Hartlib went to England, where he carried on a mercantile agency, and at the same time found leisure to enter with interest into the public questions of the day. An enthusiastic admirer of Comenius, he published in 1637 his Conatuum Comenianorum praeludia, and in 1639 Comenii pansophiae prodromus et didactica dissertatio. In 1641 appeared his Relation of that which hath been lately attempted to procure Ecclesiastical Peace among Protestants, and A Description of Macaria, containing his ideas of what a model state should be. During the civil war Hartlib occupied himself with the peaceful study of agriculture, publishing various works by himself, and printing at his own expense several treatises by others on the subject. In 1652 he issued a second edition of the Discourse of Flanders Husbandry by Sir Richard Weston (1645); and in 1651 Samuel Hartlib, his Legacy, or an Enlargement of the Discourse of Husbandry used in Brabant and Flanders, by Robert Child. For his various labours Hartlib received from Cromwell a pension of £100, afterwards increased to £300, as he had spent all his fortune on his experiments. He planned a school for the sons of gentlemen, to be conducted on new principles, and this probably was the occasion of his friend Milton’s Tractate on Education, addressed to him in 1644, and of Sir William Petty’s Two Letters on the same subject, in 1647 and 1648. At the Restoration Hartlib lost his pension, which had already fallen into arrears; he petitioned parliament for a new grant of it, but what success he met with is unknown, as his latter years and death are wrapped in obscurity. A letter from him is known to have been written in February 1661-1662, and apparently he is referred to by Andrew Marvell as alive in 1670 and fleeing to Holland from his creditors.
A Biographical Memoir of Samuel Hartlib, by H. Dircks, appeared in 1865.
HARTMANN, KARL ROBERT EDUARD VON (1842-1906), German philosopher, was born in Berlin on the 23rd of February 1842. He was educated for the army, and entered the artillery of the Guards as an officer in 1860, but a malady of the knee, which crippled him, forced him to quit the service in 1865. After some hesitation between music and philosophy, he decided to make the latter the serious work of his life, and in 1867 the university of Rostock conferred on him the degree of doctor of philosophy. He subsequently returned to Berlin, and died at Grosslichterfelde on the 5th of June 1906. His reputation as a philosopher was established by his first book, The Philosophy of the Unconscious (1869; 10th ed. 1890). This success was largely due to the originality of its title, the diversity of its contents (von Hartmann professing to obtain his speculative results by the methods of inductive science, and making plentiful use of concrete illustrations), the fashionableness of its pessimism and the vigour and lucidity of its style. The conception of the Unconscious, by which von Hartmann describes his ultimate metaphysical principle, is not at bottom as paradoxical as it sounds, being merely a new and mysterious designation for the Absolute of German metaphysicians. The Unconscious appears as a combination of the metaphysic of Hegel with that of Schopenhauer. The Unconscious is both Will and Reason and the absolute all-embracing ground of all existence. Von Hartmann thus combines “pantheism” with “panlogism” in a manner adumbrated by Schelling in his “positive philosophy.” Nevertheless Will and not Reason is the primary aspect of the Unconscious, whose melancholy career is determined by the primacy of the Will and the subservience of the Reason. Precosmically the Will is potential and the Reason latent, and the Will is void of reason when it passes from potentiality to actual willing. This latter is absolute misery, and to cure it the Unconscious evokes its Reason and with its aid creates the best of all possible worlds, which contains the promise of its redemption from actual existence by the emancipation of the Reason from its subjugation to the Will in the conscious reason of the enlightened pessimist. When the greater part of the Will in existence is so far enlightened by reason as to perceive the inevitable misery of existence, a collective effort to will non-existence will be made, and the world will relapse into nothingness, the Unconscious into quiescence. Although von Hartmann is a pessimist, his pessimism is by no means unmitigated. The individual’s happiness is indeed unattainable either here and now or hereafter and in the future, but he does not despair of ultimately releasing the Unconscious from its sufferings. He differs from Schopenhauer in making salvation by the “negation of the Will-to-live” depend on a collective social effort and not on individualistic asceticism. The conception of a redemption of the Unconscious also supplies the ultimate basis of von Hartmann’s ethics. We must provisionally affirm life and devote ourselves to social evolution, instead of striving after a happiness which is impossible; in so doing we shall find that morality renders life less unhappy than it would otherwise be. Suicide, and all other forms of selfishness, are highly reprehensible. Epistemologically von Hartmann is a transcendental realist, who ably defends his views and acutely criticizes those of his opponents. His realism enables him to maintain the reality of Time, and so of the process of the world’s redemption.
