This publication marks Schopenhauer's only major work that has not been available in English, with the exception of On the Freedom of the Human Will. This translation is based on the unparalleled historical critical edition of Schopenhauer's works, edited by Arthur Hubscher, whose text is the product of decades of careful emendation. But more importantly, this translation is almost alone the work of E.F.J. Payne, whose translations were judged by the Schopenhauer-Gesellschaft as authoritative. The appearance of this work makes nearly all of Schopenhauer's philosophical works and most of his Manuscript Remains available to the English-speaking world through the hands of a single translator, thereby providing a unity of both terminology and style to the translation of Schopenhauer's thought into English.
