The Group Mind: A Sketch of the Principles of Collective Psychology / With Some Attempt to Apply Them to the Interpretation of National Life and Character

This book outlines psychological principles underlying collective life, proposing that groups display shared mental processes shaped by instincts, emotions, suggestion, imitation, and leadership. It builds on an account of individual human nature to explain how group sentiments and beliefs form, persist, and influence behaviour, institutions, and national character. The author examines mechanisms of social cohesion, the formation of collective will, and the role of education, custom, and institutional practice in guiding group conduct. Occasional applications consider how these principles illuminate national life and practical problems in medicine, education, and public policy.
