William James and Sigmund Freud: “The Future of Psychology Belongs to Your Work”
Although James and Freud are generally not considered scientific by experimental psychologists, both wrote about their view of what a scientific psychology should look like. Their radically different philosophical epistemologies and historical origins are reviewed, to provide an understanding of their respective visions for psychology. James took his stand on a new metaphysical foundation for the way experiments should be conducted with his formulation of radical empiricism. Freud attempted a neurological explanation of the unconscious in his “Project for a Scientific Psychology.” Remarkably, their definitions of psychology as a science had a similar ring. Likely, this is because both took a phenomenological position with regard to how they defined science, which is also probably the primary reason their ideas on the subject have always been rejected by experimentalists. The humanistic implications of the neuroscience revolution, however, have caused a reassessment of their respective positions, as philosophical questions about the nature of consciousness have brought both Freud and James back into vogue, but in new and unexpected ways.
