First published in 1927, On History offers an overview of the ternds in historical thought in the earlier part of the twentieth century. Rowse starts with an analogy between historical and political thought and discusses the style and method of history writing. He argues that the chief value of the conception of history is in that it provides a principle proper to the age for its summary of the past and in the light of which we may survey the whole of the social process and not only the surface with occasional excursion into the depths. This book will be of interest to students and researchers of history.
