The thought of the late Karl Jaspers, co-founder of the existentialist movement, has long exerted a powerful influence on world opinion. But, surprisingly, though translations of his writings have appeared in over 160 editions in 16 countries, his strictly philosophical work has hitherto been largely inaccessible to American audiences. Even where adequate English translations exist, the difficulties imposed by Jaspers' involved reasoning, intricate style, and ingenious neologisms are such that few unfamiliar with Continental philosophy can hope to acquire an understanding of his ideas on their own. To overcome these barriers, Professor Wallraff as mediator, interpreter, and translator provides a clear exposition of the main themes of Jaspers' Existenzphilosophie and prepares the reader for effective study of his writings. As the first book-length introduction to Jaspers' philosophy in English, this will be an indispensable companion for anyone desiring to take up the challenge of the "loving struggle" toward the truth that Jaspers invites us all to engage in.
