Publisher's Synopsis
We are trying in this book to give some impression of the principal changes and developments of Western thought in what might roughly be called 'the last generation', though this limit of time has been, as it must be, treated liberally. From the political point of view the two most impressive milestones, events which will always mark for the consciousness of the West the beginning and the end of a period, are no doubt the war of 1870 and the Great War which has just ended. From 1870 to 1914 would therefore be the most obvious delimitation of our study; and it is a striking illustration of human paradox, that a great stage in the growth of unity should be marked by two international tragedies and crowned by the most terrible of all. Nearly coincident with the political divisions there are important landmarks in the history of thought. During the 'sixties, while the power of Prussia was rising to its culmination in the Franco-Prussian War, the Darwinian theory of development was gaining command in biology. To many thinkers there has appeared a clear connexion between that biological doctrine and the 'imperialism', Teutonic and other, which was so marked a feature of the time. In any case 'post-Darwinian' might well describe the scientific thought of the age we have in view.
