Marcus Willaschek’s book traces Kant’s revolution of thought throughout his entire oeuvre. It gives wide-ranging insights into his philosophy, which is explained in a clear and concrete way and taken out of the realm of the abstract. In 30 short standalone chapters, Willaschek presents the various themes and aspects of Kant’s thought in a clear, trenchant and comprehensible way. His explanations are interwoven with biographical and historical sketches, painting a picture of Immanuel Kant as a man and a philosopher in the context of his time. At the same time, the current relevance – and sometimes also the problematic nature – of his revolutionary thought becomes clear.
