Critical realism

Wundt determined that "psychology is an empirical science co-ordinating natural science and humanities, and that the considerations of both complement one another in the sense that only together can they create for us a potential empirical knowledge." He claimed that his views were free of metaphysics and were based on certain epistemological presuppositions, including the differentiation of subject and object in the perception, and the principle of causality. With his term critical realism, Wundt distinguishes himself from other philosophical positions.
