The article deals with Veblen’s vision of social conflict to critically reexamine his political thought. Retracing his intellectual biography, it focuses on three connected aspects: a twofold vision of social conflict that emerges from his reinvention of evolutionism; his reading of socialism in an industrial society; the relevance of an evolutionary concept of technology in order to understand new forms of conflict within the transition to a cooperative working process that is associated with scientific organization and planning.
