Originally published in German by
Suhrkamp Verlag in 2009, the book was translated into English in 2013.
Keith Ansell-Pearson received this work as "a tour de force that engages the history of philosophy, religion, and thought, both Western and Eastern, in ways that make you think deeply about the evolution of the human being these past few thousand years. As if this weren’t already enough, Sloterdijk is also concerned with the future, and on a planetary scale. Where are we heading? Where do we wish to go? More to the point, where must we go? How must we change our lives?" ==References==
