Thomas Carlyle was a man of huge influence in the nineteenth century. A prolific writer and historian, he was also a fervent campaigner for social reform, attacking the laissez-faire philosophy that was so endemic in his times. His reputation, however, plummeted soon after his death, and his unpopularity continued for many years, with critics of the twentieth century interpreting his work as a foreshadow of Fascism. In this masterly biography, Julian Symons seeks to give a balanced and lively account of the life and work of this controversial man. He reveals him to be an eccentric figure, a man of literary genius and immense social influence but also a man plagued by his own personal tragedy.
