Keith Taylor 
Political Ideas of the Utopian Socialists [PDF ebook] 

First Published in 1982. In this book, Taylor has selected for special attention the work of Saint-Simon and his disciples (the Saint Simonians), Owen, Fourier, Cabet, and Weitling – those thinkers who made the most important contributions to the development of early socialist theory. The author discusses the designation of ‘utopian’ which entered into the conventional vocabulary of the history of ideas, and is now used almost without question. This title argues that these thinkers were certainly utopian in the sense that they sought to describe the structure of an ideal future society.
