as an attempt to mediate between Kant's apriorism and empiricism. Moral rules are the legislative results of a universal intellectual development, but are neither rigidly defined nor do they simply follow changing life conditions. Individualism and utilitarianism are strictly rejected. In his view, only the universal intellectual life can be considered to be an end in itself. Wundt also spoke on the idea of humanity in ethics, on human rights and human duties in his speech as Rector of Leipzig University in 1889 on the centenary of the French Revolution. Logic, epistemology and the scientific theory of psychology Wundt divided up his three-volume Logik into General logic and epistemology, Logic of the exact sciences, and Logic of the humanities. While logic, the doctrine of categories, and other principles were discussed by Wundt in a traditional manner, they were also considered from the point of view of development theory of the human intellect, i.e. in accordance with the psychology of thought. The subsequent equitable description of the special principles of the natural sciences and the humanities enabled Wundt to create a new epistemology. The ideas that remain current include epistemology and the methodology of psychology: the tasks and directions of psychology, the methods of interpretation and comparison, as well as psychological experimentation. Complete works and legacy Publications, libraries and letters The list of works at the Max Planck Institute for the History of Science includes a total of 589 German and foreign-language editions for the period from 1853 to 1950 MPI für Wissenschaftsgeschichte: Werkverzeichnis Wilhelm Wundt.The American psychologist Edwin Boring counted 494 publications by Wundt (excluding pure reprints but with revised editions) that are, on average, 110 pages long and amount to a total of 53,735 pages. Thus Wundt published an average of seven works per year over a period of 68 years and wrote or revised an average of 2.2 pages per day. There is as yet no annotated edition of the essential writings, nor does a complete edition of Wundt's major works exist, apart from more-or-less suitable scans or digitalisations. Apart from his library and his correspondence, Wundt's extraordinarily extensive written inheritance also includes many extracts, manuscripts, lecture notes and other materials Wundt's written inheritance in Leipzig consists of 5,576 documents, mainly letters, and was digitalised by the Leipzig University Library. The catalogue is available at the Kalliope online portal. One-third of Wundt's own library was left to his
