Diogenes has set itself the task to present to its readers the most recent developments in all important branches of the Humanities. Among the most burning questions in the sphere of contemporary political sciences is the one raised by the almost universal demand for the ‘Welfare State’.

The twentieth-century state owes to man not only order, peace, and justice, it owes him also material well-being. The search for and the study of the means by which public power can provide for such well-being have added an important chapter to the history of political theory and the art of government.

Professor A. C. Pigou has had a decisive part in the genesis of this great intellectual and moral mutation. He is the uncontested master of the new technique. Diogenes is proud and happy indeed to have the privilege of presenting his original and deep thoughts on the idea of the State as the producer of well-being, on the origins of this concept and the methods of its development. These ideas throw new light on the evolution of the great modern states and put a new and efficient tool into the hands of those who strive to understand and explain this evolution.
