In 1904, Paul G. Natorp (1854—1924) published his lectures on general psychology. This article shows that this purely philosophical, yet systematic work describes those issues of psychologism and psychology which would prove most important to the intellectual life of Europe at the turn of the century, and which Natorp
interprets in accordance with the provisions of transcendental philosophy. From the perspective of a representative of the Marburg School of Neo-Kantianism, he outlines the philosophical profile of the subject and the method of psychology. He focuses his discussion on the problem of understanding consciousness and highlights the following elements: the content of consciousness, the consciousness of Ego and the relationship between the content of consciousness and the conscious Ego. His analysis is performed from the bottom up (physiology), depicting the mechanics of the operation of the human nervous system. The article addresses the question of the critical interpretation of Paul Natorp’s general psychology, with emphasis on cognitive and relational functions of consciousness (Bewusstsein).
