Published here for the first time is much of a final and long-anticipated work on the philosophy of history by the great Oxford philosopher and historian R. G. Collingwood (1889-1943). The original text of this uncompleted work has only recently been discovered and is accompanied here by shorter writings by Collingwood on historical knowledge and inquiry. Besides containing entirely new ideas, these incredible writings discuss many of the issues which Collingwood famously raised in The Idea of History and in his Autobiography. This book also includes two conclusions written by Collingwood, which were eventually revised and published as The Idea of Nature. Moreover, this book contains a lengthy editorial introduction that puts Collingwood's writings in their context and discusses the philosophical questions they initiate. A landmark publication, this work will appeal not only to those studying Collingwood but also to anyone broadly curious about philosophy of history.
