Heinrich Simon Lindemann (1807–1855), follower of Karl C. F. Krause and successor to Schelling’s chair in Munich, refined and extended Krause’s view of science and the soul. Both begin their inquiry by pointing to the undoubted self-knowledge of the I, corresponding to the principle of unity. This unity of the I is divided into body and spirit and unified in the soul. Unity, counter-unity, and coherence are principles that can be found in its purest form in God, the ground of the world, and extend to all human beings. Lindemann describes the essence of human beings not functionally-mechanistically separated in parts but organized in members. A corresponding organic doctrine of the soul allows thinking the human being from its individual essence, which forms neither an aggregate nor emergent phenomenon, while including its position to nature and to other spirits. For Lindemann, a study of the soul that did not even raise the question of the essence of the soul and its knowledge would have been a contradiction in terms. The determination of essence that Lindemann undertakes claims not to be a nominalistic designation or spatial attribution but a knowledge of entities, which come true in life.
