This book is a reissue of a long out-of-print translation of a major sixteenth-century philosophical text, with new introduction, annotation and bibliography. Lipsius' De Constantia (1584) is a key Humanist text. A dialogue in two books, conceived as a philosophical consolation for those suffering through contemporary religious wars, it proved immensely popular in its day and formed the inspiration for what has become known as 'Neostoicism'. This movement advocated the revival of Stoic ethics in a form that would be palatable to a Christian audience. Lipsius deploys Stoic arguments concerning appropriate attitudes towards emotions and external events. He also makes clear which parts of stoic philosophy must be rejected, including its materialism and its determinism. De Constantia was translated into a number of vernacular languages soon after its original publication in Latin. Of the English translations which were made, that by Sir John Stradling (1594) became a classic; it was last reprinted in 1939. The present edition offers a lightly revised version of Stradling's translation, updated for modern readers, along with a new introduction, notes and bibliography. * English translation of a major philosophical text from the Renaissance. * First in a new series devoted to Renaissance Neo-Latin: 'The Neo-Latin Library'.
