Socialism: A Summary and Interpretation of Socialist Principles is an early twentieth-century exposition by John Spargo, an English-born writer who became a prominent figure in the American socialist movement. The book aims to present socialism clearly and sympathetically to a general audience, setting out its history, economic theory, and ethical claims.
Spargo explains the socialist critique of capitalism, the labor theory of value, and the goals of common ownership and social reform, while distinguishing socialism from anarchism and other rival movements. Written during a period when socialist ideas were gaining ground in Europe and America, it serves as both an argument and a historical record of the movement’s mainstream thought. The work is offered here as a free EPUB download.
