This new edition of Hobbe's masterpiece is uniquely suited to meet the needs of both student and scholar. It offers a brilliant introduction by Edwin Curley, modernised spelling and punctuation of the text, and a key annotative feature found in no other edition: the inclusion, along with historical and interpretive notes, of the most significant variants between the English version of 1651 and the Latin version of 1668. A glossary of seventeenth century English terms and indexes of persons, subjects, and scriptural passages help make this the most thoughtfully conceived edition of Leviathan available.
