Karl Fortlage (German: [ˈfɔɐ̯tˌlaːɡə] ; 12 June 1806 – 8 November 1881) was a German philosopher.
Born in Osnabrück, Fortlage taught in Heidelberg and Berlin before becoming professor of philosophy at Jena in 1846 (1846 associate professor, 1860 honorary professor), [1] a post he held until his death. Originally a follower of Hegel, he turned to Fichte and the psychologist Friedrich Eduard Beneke, agreeing with his assertion that psychology is the basis of all philosophy. The fundamental idea of his psychology is impulse, which combines representation (thereby presupposing consciousness) and feeling (i.e. pleasure). Reason is the highest thing in nature, i.e. it is divine in its nature. God is the absolute Ego, and the empirical egos are his instruments.
Wilhelm Maximilian Wundt was a German physiologist, philosopher, and professor, one of the fathers of modern psychology. Wundt, who distinguished psychology as a science from philosophy and biology, was the first person ever to call himself a psychologist.
Friedrich Wilhelm Joseph Schelling, later von Schelling, was a German philosopher. Standard histories of philosophy make him the midpoint in the development of German idealism, situating him between Johann Gottlieb Fichte, his mentor in his early years, and Georg Wilhelm Friedrich Hegel, his one-time university roommate, early friend, and later rival. Interpreting Schelling's philosophy is regarded as difficult because of its evolving nature.
Friedrich Daniel Ernst Schleiermacher was a German Reformed theologian, philosopher, and biblical scholar known for his attempt to reconcile the criticisms of the Enlightenment with traditional Protestant Christianity. He also became influential in the evolution of higher criticism, and his work forms part of the foundation of the modern field of hermeneutics. Because of his profound effect on subsequent Christian thought, he is often called the "Father of Modern Liberal Theology" and is considered an early leader in liberal Christianity. The neo-orthodoxy movement of the twentieth century, typically seen to be spearheaded by Karl Barth, was in many ways an attempt to challenge his influence. As a philosopher he was a leader of German Romanticism. Schleiermacher is considered the most important Protestant theologian between John Calvin and Karl Barth.

Hans Bender was a German lecturer on the subject of parapsychology, who was also responsible for establishing the parapsychological institute Institut für Grenzgebiete der Psychologie und Psychohygiene in Freiburg. For many years his pipe smoking, contemplative figure was synonymous with German parapsychology. He was an investigator of 'unusual human experience', e.g. poltergeists and clairvoyants. One of his most famous cases was the Rosenheim Poltergeist.
Carl Gustav Carus was a German physiologist and painter, born in Leipzig, who played various roles during the Romantic era. A friend of the writer Johann Wolfgang Goethe, he was a many-sided man: a doctor, a naturalist, a scientist, a psychologist, and a landscape painter who studied under Caspar David Friedrich.

Versuch einer Metaphysik der inneren Natur is a book written by German author Heinrich Schmid (1799–1836). It was published by Brockhaus Leipzig in 1834. In this book, Schmid attempts to develop a metaphysical account of humans' inner nature, the soul, in terms of general laws. These laws, Schmid proposes, should be based on empirically gathered knowledge about inner nature. He argues, that with the formulation of such laws, psychology, the science of the human soul, should become a natural science like physics. Schmid's ideas build heavily on the philosophy of Immanuel Kant, for which he was criticized. He belonged to the philosophical school surrounding Jakob Friedrich Fries, whose ideas are associated with Neo-Kantianism. Schmid's theories, especially concerning memory, were adopted by Sir William Hamilton, whose philosophy was discussed by John Stuart Mill at the end of the 19th century. Wilhelm Wundt and his contemporaries still used methods similar to Schmid's structured introspection once psychology was founded as an independent discipline in 1879.
Friedrich Jodl was a German philosopher and psychologist.
