This is the first full-length biography in more than fifty years of Immanuel Kant, one of the giants amongst the pantheon of Western philosophers as well as the one with the most powerful and broad influence on contemporary philosophy. It is well known that Kant spent his entire life in an isolated part of Prussia living the life of a typical university professor. This has given rise to the view that Kant was a pure thinker with no life of his own, or at least none worth considering seriously. In this biography, Manfred Kuehn debunks that myth once and for all. Taking account of the most recent scholarship Professor Kuehn allows the reader (whether interested in philosophy, history, politics, German culture, or religion) to follow the same journey that Kant himself took in emerging as a central figure in modern philosophy.
