Hier et demain: pensées brèves

About this book

"Hier et demain : pensées brèves" by Gustave Le Bon is a philosophical treatise written in the early 20th century. This work explores the psychological and moral impacts of war, particularly focusing on the changes in societal beliefs and structures as a result of conflict and challenges to traditional understandings of governance and morality. The author reflects on how the Great War has forced societies to confront deep questions about justice, truth, and their collective psyche. At the start of the text, Le Bon introduces the profound transformations brought about by the ongoing conflict, noting that the destruction extends beyond physical realms to moral and psychological realms. He suggests that the war has dismantled old certainties and ideologies, forcing individuals to grapple with new realities that challenge previously-held beliefs. The opening serves as a foundation for his exploration of various psychological forces—biological, affective, mystical, and collective—that drive human behavior and shape historical events, setting the stage for subsequent discussions on the psychology of nations and individuals.
