Karl Jaspers 
Man in the Modern Age (Routledge Revivals) [PDF ebook] 

First published in English in 1933, this detailed philosophical examination of the contemporary state and nature of mankind is a seminal work by influential German philosopher Karl Jaspers. Elucidating his theories on a variety of topics pertaining to contemporary and future human existence, Man in the Modern Age is an ambitious and wide-ranging work, which meditates upon such diverse subjects as the tension between mass-order and individual human life, our present conception of human life and the potential for mankind’s future existence. Written shortly before the accession to power of Hitler and National Socialism, this is not only an important philosophical work, but also an insightful and intriguing historical document.
