Set in early eighteenth-century Scotland, James Hogg's masterpiece is a brilliant psychological study of religious fanaticism and the power of evil. Led on by his sinister companion, Gil-Martin, Robert Wringhim commits a series of atrocious crimes. As the novel progresses, however, and the complexity of Wringhim's mind is revealed, the reader begins to doubt whether Gil-Martin even exists. This edition of The Private Memoirs and Confessions of a Justified Sinner places the work within the context of Calvinism, Scottish political and constitutional history, and early psychological theories of "double consciousness." A wide-ranging introduction discusses the novel in relation to its setting as well as to the period in which it was composed.
