Friedrich Eduard BenekeBorn 17 Feb 1798; died 1 Mar 1854 at age 56.German philosopher and psychologist who 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. Although he never carried out such experiments himself, Beneke demanded that psychologists should develop their theories, and test them, under controlled conditions and with the systematic variation of variables. |
