The late 19th-century Ignorabimus controversy over the limits of scientific knowledge has often been characterized as proclaiming the end of intellectual progress, and by implication, as plunging Germany into a crisis of pessimism from which Liberalism never recovered. My research supports the opposite interpretation. The initiator of the Ignorabimus controversy, Emil du Bois-Reymond, was a physiologist who worked his whole life against the forces of obscurantism, whether they came from the Catholic and Conservative Right or the scientistic and millenarian Left. (...) Du Bois-Reymond’s doubt that scientists would ever elucidate consciousness must therefore be seen as an endorsement, and not a rejection, of his faith in reason. (shrink)

The ArgumentThe history of psychology, like other human science subjects, should attend to the meaning of words understood as relationships of reference and value within discourse. It should seek to identify and defend a history centered on representations of knowledge. The history of the word “inhibition” in nineteenth-century Europe illustrates the potential of such an approach. This word was significant in mediating between physiological and psychological knowledge and between technical and everyday understanding. Further, this word indicated the presence of a (...) common discourse structuring ways of thought about order, whether in technology, moral activity, or experimental psycho-physiology. Writing history as the history of discourse suggests several difficulties; these are considered briefly. Nevertheless attention to language and meaning makes it possible to integrate the history of psychology with intellectual history and thereby to broaden its potential audience. (shrink)
