Struck by the absence of love affairs, adventures, travels, and political engagement in Immanuel Kant's life, a noted commentator describes him as unformed, to a degree surpassing all other philosophers, by challenging life events. Declaring that Kant 'can be understood only through his work in which he immerses himself with unwavering discipline,' the writer evokes the image of a body of writing demanding to be understood through text-internal analytical methods alone. The theme of the enclosed Kantian text is virtually irresistible. It dominates in teaching practice and in a large percentage of the expository literature, where Kant's ideas are paraphrased in more, or even less transparent prose. It is attributable to the fact that Kant is a difficult author, a fact that, despite his scorn for popular philosophy, he knew and to some extent regretted. The commentator too is apt to immerse him or herself in Kant's writings with unwavering discipline, leaving little time and energy for a study of Kant's surrounding context. Like Wordsworth's Isaac Newton, whose innate powers enable him to teach the truth to himself, Kant is seen as a walled-off genius whose innovations nevertheless reached to the whole world. But Kant's famous domesticity and addiction to routine did not preclude contact with an external world. His mind was formed--as was Newton's, as is that of any one of us-- by his encounters with books and essays, by his exchanges with correspondents and dinner guests, from whom he learned and by whom he was provoked and challenged. The name index of the Academy Edition of Kant's works and the range of authors in the catalogue of Kant's library books published by Arthur Warda in 1922 leave no doubt as to the breadth of his personal and literary acquaintances"--
