Peter Sloterdijk, professor of philosophy and aesthetics at the Karlsruhe School of Design, is one of Germany’s most creative minds. A philosopher, cultural theorist and public intellectual, his prolific and lively writings cover everything from religion and art to globalization and genetic engineering. He rose to fame in the 1980s with his bestselling book Critique of Cynical Reason, but his trilogy Spheres, published in the late 1990s and early 2000s, is his magnum opus. In Spheres and in his influential book You Must Change Your Life (Polity, 2012), Sloterdijk presents a new analysis of our age, showing that as humans we increasingly affirm our own existence through our activities and training, rather than seeking recourse to religion. Sloterdijk’s characteristic method of defamiliarisation can be seen across his oeuvre, challenging assumed ideas and offering a fresh and often startling perspective on everyday realities as much as the fundamental questions of life. Polity publishes most of Sloterdijk’s work including In the World Interior of Capital, God’s Zeal, The Aesthetic Imperative and What Happened in the 20th Century?
