could not say that the scientific conception of psychology underwent a fundamental revision of principal ideas and central postulates, though there was gradual development and a change in emphasis. One could consider Wundt's gradual concurrence with Kant's position, that conscious processes are not measurable on the basis of self-observation and cannot be mathematically formulated, to be a major divergence. Wundt, however, never claimed that psychology could be advanced through experiment and measurement alone, but had already stressed in 1862 that the development history of the mind and comparative psychology should provide some assistance. Wundt attempted to redefine and restructure the fields of psychology and philosophy. "Experimental psychology in the narrower sense and child psychology form individual psychology, while cultural and animal psychology are both parts of a general and comparative psychology"). None of his Leipzig assistants and hardly any textbook authors in the subsequent two generations have adopted Wundt's broad theoretical horizon, his demanding scientific theory or the multi-method approach. Oswald Külpe had already ruled cultural and animal psychology out. While the Principles of physiological Psychology met with worldwide resonance, Wundt's cultural psychology (ethno-psychology) appeared to have had a less widespread impact. But there are indications that George Herbert Mead and Franz Boas, among others, were influenced by it. In his Totem and Taboo, Sigmund Freud frequently quoted Wundt's cultural psychology. In its time, Wundt's Ethik received more reviews than almost any of his other main works. Most of the objections were ranged against his renouncing any ultimate transcendental ethical basis (God, the Absolute), as well as against his ideas regarding evolution, i.e. that ethical standards changed culturally in the course of human intellectual development. As Wundt did not describe any concrete ethical conflicts on the basis of examples and did not describe any social ethics in particular, his teachings with the general idea of humanism appear rather too abstract. The XXII International Congress for Psychology in Leipzig in 1980, i.e. on the hundredth jubilee of the initial founding of the Institute in 1879, stimulated a number of publications about Wundt, also in the US Very little productive research work has been carried out since then. While Wundt was occasionally mentioned in the centenary review of the founding of the German Society for Experimental Psychology 1904/2004, it was without the principal ideas of his psychology and philosophy of science. Research on reception of his work Leipzig was a world-famous centre
