Ernst Mach and Wilhelm Jerusalem may be considered exponents of a homegrown European version of pragmatism. The purpose of this paper is to highlight the strongly social orientation Jerusalem gave to his. Particular attention will be paid to some of his predecessors to exhibit the relevance of a pioneering but largely forgotten type of social science for the development of his version of European pragmatism. Broadly speaking, considerations from Völkerpsychologie played the role for the development of Jerusalem’s views that considerations (...) from the history of science played for the views of Mach. Of particular interest to us here is how these broadly sociological ideas fed into Jerusalem’s philosophy and his understanding and appreciation of pragmatism. (shrink)
