A Conceptual History of Psychology is a broad historical survey that traces conceptual continuities and discontinuities in the history of psychological thought. The author connects the history of psychological theory with the development of the history of science, from the proto-scientific psychology of the 17th and 18th centuries to the institutionalized scientific psychology of the late 19th century to the present day. The lucid writing style and clear organization reflect the author's fifteen years' experience teaching the course.
