La vie des vérités

About this book

La vie des vérités by Gustave Le Bon is a philosophical and sociological treatise written in the early 20th century. It explores how “truths” and, especially, certainties arise, spread, harden, and decay across religion, morality, philosophy, and science, stressing the power of collective psychology, rites, and symbols. Expect a sweeping analysis that distinguishes truth from certainty, classifies kinds of truths, and argues that hypotheses—scientific or religious—create real effects in societies.

The beginning of this treatise sets its aim: to trace the origins and transformations of great religious, philosophical, and moral beliefs, warning against rejecting the past while urging clear guidance for action. It defines truth versus certainty, classifies truths (biological, affective, mystic, collective, rational), argues that truths are absolute yet transitory, and defends hypotheses (from ether and atoms to gods and moral codes) as indispensable guides that shape realities. It then opens the “cycle of mystical certainties,” grounding religion in mysticism, fear, hope, imagination, the need for explanation, and the desire for immortality, while showing reason’s minor role and the unifying force of rites and symbols. The text highlights how doctrines change when they become popular or cross cultures: monotheisms turn practically polytheist, Brahmanism and especially Buddhism shift in practice, and ordinary believers treat divinities as powerful patrons to be won by offerings. It emphasizes analogies among religions across peoples and times. Finally, it sketches early cults (totemism, animism, fetishism) as overlapping, notes the persistence of fetish-like habits today, describes the pervasive religiosity of the Greco-Roman world, and details the enduring cult of the dead—before moving toward the divinization of abstractions and heroes.
