SUPPLEMENTARY BIBLIOGRAPHY

Rudolf Hermann Lotze (1817–1881), German psychologist and philosopher, was born in Bautzen, Upper Lusatia. His father was a surgeon in the army of Saxony. In the confusion of the Napoleonic Wars, his family moved frequently, finding a permanent home only in 1818 in Zittau. There, in 1828, Lotze entered the excellent classical Gymnasium, graduating cum laude in 1834. In his last years at the Gymnasium, he wrote poetry, as well as a novelistic essay along the lines of Goethe’s Wilhelm Meister. Strongly influenced by Goethe, and as yet unaware of the works of other thinkers, he began to develop what were to remain the essentials of his philosophy.

Lotze’s lack of funds forced him to abandon his literary and other interests and prepare himself for a profession. Following in his father’s footsteps, he began, in 1834, to study medicine at the University of Leipzig. He also studied philosophy under Christian H. Weisse, a friend of Fechner’s and an adherent of the idealist philosophy of Schelling and Hegel. Lotze’s later work was decisively influenced both by his medical and scientific training and by Weisse’s idealist teaching.

He completed his study of medicine in 1838 with a dissertation entitled De futurae biologiae principiis philosophicis. As a scientist he vigorously opposed the medical mysticism implied in the concept of “vitality,” replacing it with mechanistic explanations; as a philosopher, however, he denied that a mechanistic system of explanation is necessarily based on a materialist philosophy. He obtained a master’s degree in philosophy at the same time as his medical degree.

Lotze practiced medicine in Zittau for a year, but he soon found the town too confining. Encouraged by his former professor, Weisse, he returned to Leipzig as an instructor in medicine and philosophy; he was appointed associate professor in 1843. While he was at Leipzig he produced the outlines of his scientific life work: the Metaphysik (1841), in which he broke with Hegelian idealism; the Allgemeine Pathologic und Therapie als mechanische Naturwissenschaften (1842); the Logik (1843a); and three articles for Rudolf Wagner’s Handwörterbuch der Physiologic, “Leben, Lebenskraft” (1843b), “Instinct” (1844), and “Seele und Seelenleben” (1846). In 1844 he accepted an appointment as full professor at Gottingen, occupying what had been Johann Friedrich Herbart’s chair. He remained at Gottingen for 37 years until, at the urging of Eduard Zeller and Helmholtz, he accepted the chair vacated by Harms in Berlin. He died soon after his move to Berlin.

Lotze always remained both a scientist and a philosopher. His works are characterized, first, by his efforts to eliminate mysticism from science by using the causal—mechanistic method and, second, by his concern to dissociate mechanistic systematization from materialist-atheist philosophy. To Lotze intellectual achievement without faith was a caput mortuum, and science without causal-mechanistic systematization was not a science. Ultimately, to be sure, what concerned him was the ideal—what ought to be—and he saw the understanding of causal relationships simply as a condition for the realization of the ideal. Thus, mechanistic processes are indispensable to the existence of a phenomenon, but they are not its raison d’être. In this way Lotze tried to combine mechanistic systematization with ethical freedom, with what he called the dignity of subjectivity. In his own time his postulate of freedom, which went counter to the anti-idealist Zeitgeist, was not understood; his contemporaries availed themselves, instead, of the mass of physiological facts he cited —which clearly confirmed the dependence of the psychical on the physical—to support their materialist philosophy.

Lotze’s Allgemeine Physiologie des koerperlichen Lebens appeared in 1851, and his Medicinische Psychologic: Oder, Physiologie der Seele in 1852. The latter is the first physiological psychology, the prototype of all later works bearing similar titles. In contrast to Fechner’s parallelism, Lotze’s psychology is a theory of interaction: sensation is produced by the mind “at the initiative of a neural state.” Space is a mode of perception peculiar to the mind. A corollary to this theory of space perception is Lotze’s theory of” local signs,” which asserts that the world of external space is never simply perceived but rather reproduced by the mind.

His two-volume magnum opus, Microcosmus (1856–1864), has two aspects: it is both a polemic against materialist philosophy and an expansion of Lotze’s psychology into a comprehensive anthropology. (Its German subtitle is “Versuch einer Anthropologie.”) Exploring what he called education (Bildung), that is, the conditions under which a human being becomes human, he dealt with such subjects as national temperament, the evolution of customs and morals, and the influences of home, family, division of labor, and so forth. He regarded the history of mankind as the history of the evolution of the human mind.

Lotze founded no school; he had no disciples. Yet he was a pioneer with some influence, for the friends and pupils he did have were men of scientific importance: Teichmüller, Stumpf, Konrad Langenbeck, and Georg E. Miiller. Stumpf studied with Lotze in 1867–1868, and, after working with Franz Brentano in Würzburg for two years, he returned to Göttingen as an instructor. Müller took his doctorate with Lotze in 1873, became an instructor at Güttingen in 1876, and succeeded Lotze as professor there in 1881.

It is unlikely that anyone with an empirical, problem-oriented approach to psychology will find Lotze’s work of direct relevance. But if he does not dismiss Lotze’s work too readily as obsolete, he may find fertile suggestions there.
