On February 17, 1798, German psychologist and post-Kantian philosopher Friedrich Eduard Beneke was born. Beneke argued that inductive psychology was the foundation for the study of all philosophical disciplines. He rejected the existing idealism for a form of associationism influenced by both Immanuel Kant and Locke. Beneke agreed with Herbart’s general idea that mathematics should be introduced into psychology, but he felt that Herbart’s attempt to quantify psychological phenomena was insufficiently empirical. Beneke suggested that more precise observations were needed, through psychological experiments.
Friedrich Eduard Beneke enrolled at the University of Halle and also studied at the University of Berlin. After first studying theology under Friedrich Schleiermacher and Wilhelm Martin Leberecht de Wette, Beneke became more enthusiastic about philosophy. He studied English writers as well as Friedrich Jacobi, Jakob Fries, and Arthur Schopenhauer. Friedrich Beneke’s first important work Erkenntnisslehre, Erfahrungsseelenlehre als Grundlage alles Wissens and his dissertation De Veris Philosophiae Initiis were published in 1802.
Friedrich Beneke became privatdozent in Berlin, where his lectures were prohibited in 1822 due to Beneke’s strong opposition to Hegel who was back then quite dominant in the area. Therefore, Beneke began lecturing in Göttingen and was allowed to return to Berlin in 1832 where Beneke received an appointment as professor extraordinarius at the university.
When Friedrich Beneke began to study psychology, he began to maintain that in empirical psychology is to be found the basis of all philosophy, and his rigid treatment of mental phenomena by the genetic method. Beneke developed the idea that the perfected mind is a development from simple elements, and the first problem of philosophy is the determination of these elements and of the processes by which the development takes place. Beneke promoted that psychology should be considered as part of the natural sciences.
Beneke assumed that originately there is no “formed product” in the mind, and further that definite faculties do not originally exist. Instead, the soul consists of a variety of powers, faculties or forces, differing from one another only in tenacity, vivacity, receptivity and grouping. The primitive immaterial forces further acquire definiteness or form through the action upon them of stimuli or excitants from the outer world. Hence, external impressions appropriated by the internal powers is the first fundamental process in the genesis of the completed mind. If the union of impression and faculty be sufficiently strong, consciousness arises, and definite sensations and perceptions begin to be formed.
The primitive sensations are however not to be identified with the special senses, for each of these senses is a system of many powers which have grown into a definite unity, have been educated by experience. According to Beneke, the process of the formation of new powers mainly takes place during sleep. Further, the combination between stimulus and power may be weak or strong. If the combination is weak, tile two elements are said to be movable, and they may flow over from one to another of the already formed psychical products. However, a formed faculty still exists on the removal of its stimulus and sinks back as a trace into unconsciousness. There, the faculty may be recalled by the application of a stimulus or by the attraction towards it of some of the movable elements or newly formed original powers. The described traced and the flowing over of the movable elements are the most important conceptions in Beneke’s psychology. Beneke manages to explain that formed faculties are simply developments from traces of earlier processes. According to Beneke, the process of mental development is therefore the result of the action and interaction of the simple laws.
On 1 March 1854 he disappeared, and more than two years later his remains were found in the canal near Charlottenburg. There was some suspicion that he had committed suicide in a fit of mental depression.
