opening of the work sets the stage for an exploration of the psychological underpinnings of crowd behavior, contrasting individual and collective mental states. Le Bon introduces the idea that crowds can exhibit specific psychological traits that are distinct from those of individuals, particularly when influenced by shared emotions or stimuli. He emphasizes the unconscious aspects of collective behavior, detailing how individuals in crowds often act impulsively, driven by shared sentiments rather than rational thought. This serves as a precursor to a broader analysis of the powerful influence of crowds on historical change and social dynamics, signifying the importance of understanding crowd psychology for those engaged in leadership and policymaking.
