 W. H. Walsh’s Philosophy of History (Walsh 1960 [1951]), first published in 1951 and revised in 1960, is an open-minded and well-grounded effort to provide an in-depth presentation of the field that crosses the separation between continental and analytical philosophy. The book attempts to treat both major questions driving much of the philosophy of history: the nature of historical knowledge and the possibility of gaining “metaphysical” knowledge about history. An Oxford philosopher trained in modern philosophy, Walsh was strongly influenced by Collingwood and was well aware of the European idealist tradition of philosophical thinking about history, including Rickert, Dilthey, and Croce, and he treats this tradition in a serious way. He draws the distinction between these traditions along the lines of “critical” and “speculative” philosophy of history. Walsh’s goal for the book is ambitious; he hopes to propose a framework within which the main questions about history can be addressed, including both major traditions. He advances the view that the historian is presented with a number of events, actions, and developments during a period. How do they hang together? The process of cognition through which the historian makes sense of a set of separate historical events Walsh refers to as “colligation” — “to locate a historical event in a larger historical process in terms of which it makes sense” (23).
