Les Opinions Et Les Croyances: Genèse; Évolution

Written by the pioneer of crowd psychology, this 1911 treatise dissects the invisible architecture of human belief. Le Bon argues that what we call 'belief' has almost nothing to do with reason: it emerges from the unconscious, fed by emotion, desire, habit, and pain. Knowledge can be debated; belief cannot, because it anchors itself in something deeper than logic. The book builds a provocative framework for understanding how individuals and societies form their convictions, and why those convictions wield more power over history than any rational argument. Le Bon critiques existing psychology for ignoring the affective roots of thought, then constructs his own model of personality and collective ideals. A century before behavioral economics and neuroscience revived these questions, Le Bon saw that the mind is not a rational calculator but a battlefield of instincts, feelings, and unconscious forces. For readers interested in the foundations of how people believe what they believe, this remains a disturbing and electrifying starting point.
