This chapter addresses the rise of psychology without a soul. There were scientific conceptions of psychology with a soul in the eighteenth century. Psychologies without soul followed from David Hume’s treatment of mental life. Lange coined the phrase, “psychology without a soul,” promoting a scientific psychology free of metaphysics. Soulless psychology emerged with psychology as a natural science in Newtonian terms. It also reflected debates over the distinction between the mental and the physical and the status of the “knower” in consciousness. The chapter includes debates over “psychology without a soul," and the development of an objective psychology in behaviorism. The new psychology without a soul triumphed by 1910, when Angell declared that the funeral for the soul had been held.
