A History of Philosophical Psychology prior to and after the divorce of Psychology as a Science from the discipline of Philosophy. The Greeks and especially Aristotle laid the foundations for Philosophical Psychology: a foundation free of the metaphysics of dualism and materialism. Unfortunately, the foundation of Aristotle's hylomorphism did not prevail because of the Latinisation of the Greek language. When Aristotle's Philosophy did re-emerge Science in both dualistic and materialistic form dominated the cultural landscape. Kant's Philosophy attempted to correct this situation but was overshadowed by Hegel's Spiritualism and Marx's dialectical materialism. Psychology detached itself from Philosophy in this environment.
