This is the first systematic attempt to compare Herodotus and Thucydides as contemporaries, that is, as pre- Socratic thinkers who employed rather similar concepts and intellectual tools and who worked within the same theoretical framework or space. The work also brings to the study of the ancient historians widely accepted and recognizable concepts derived from contemporary historiography and the methodology of the social sciences. Originally published in 1982. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
