It is important for every student of psychology, wherever they might be in the world, to understand the classic scholars, the classic studies, and the subsequent generations of people and ideas that have come to define the broad discipline that is 'psychology'. This book achieves this in the most accessible and engaging manner possible. Rom Harré presents a unique textbook orientation, combining the biopic with the significance of the major protagonists of the last century, organized by 'schools of thought', yet with cross-references throughout the text.
