We often imagine that the emergence of industrialized societies followed a disenchantment and a rationalizing of human activity. This is exact, but not yet true. Indeed, a closer examination of the father of industrialism, Claude-Henri de Saint-Simon, and of scientific management, Frederick Winslow Taylor, reveals the significant influence William Penn and the Quakers exercized in the formation of this project. It thus appears that industrialized societies too proceed from secularizing tendencies which buttress these societies’ utopia of efficient cooperation.
