He was educated at the grammar school of Zittau; he had an enduring love of the classical authors, publishing a translation of Sophocles' Antigone into Latin verse in his middle life.
Lotze's first work was his dissertation De futurae biologiae principibus philosophicis, with which he gained in July 1838 the degree of doctor of medicine.
Published as they were during the years when the modern school of German materialism was at its height, these works of Lotze were enrolled in the opposing camp of empirical philosophy.
Lotze worked in a post-revolutionary time of transition between the idealistic and rationalist legacies of Leibniz, Kant and Hegel and the new materialism and scientific interpretation of reality.
