McManus presents a comprehensive guide to the liberal socialist tradition, stretching from Mary Wollstonecraft and Thomas Paine through John Stuart Mill to Irving Howe, John Rawls, and Charles Mills.

Providing a comprehensive critical genealogy of liberal socialism from a sympathetic but critical standpoint, McManus traces its core to the Revolutionary period that catalyzed major divisions in liberal political theory to the French Revolution that saw the emergence of writers like Mary Wollstonecraft and Thomas Paine who argued that liberal principles could only be inadequately instantiated in a society with high levels of material and social inequality to John Stuart Mill, the first major thinker who declared himself a liberal and a socialist and who made major contributions to both traditions through his efforts to synthesize and conciliate them. McManus argues for liberal socialism as a political theory which could truly secure equality and liberty for all.

An essential book on the tradition of liberal socialism for students, researchers, and scholars of political science and humanities.
