A British variant of logical realism emerged at the end of the nineteenth century that was different from the mainstream variants of logical realism defended on the Continent. This difference can partly be explained in terms of the empiricist tradition in Britain and the British variant of idealism. These factors do not completely explain, though, the typical characteristics of Moore and Russell's variant of logical realism and the way analytic philosophy took shape in Britain. Is it possible that the new development of psychology as a science played a determining role here?
