Auguste Comte et Herbert Spencer / Contribution à l'histoire des idées philosophiques au XIXe siècle

A critical study analyzes the nineteenth-century dispute between monism and agnosticism by comparing two leading thinkers. It traces three dominant currents in one thinker's positivism—the insistence on epistemic limits, the emphasis on historical and evolutionary development, and an attenuated scientific monism—and argues that rigid agnosticism undermines asserted claims to unity. The work contrasts that stance with a more daring monistic tendency in contemporary philosophy, examines logical tensions arising from combining a pledge to unity with claims of unknowability, and maps how these opposing impulses shaped broader debates about scientific method and philosophical synthesis.
