This is Volume V of fifteen in the Sociology of Law and Criminology series. Originally published in 1946, readers of the present volume will be aware of the links existing, for instance, between certain chapters of the author's previous work 'Social Aspects', especially those on Business Administration and similar subjects, and the economic sections of the present book; or between the concluding Parts of the latter and of 'The Dilemma'. A few lectures of a programmatic character delivered at a Summer School of the Fabian Society and at the South Place Ethical Society also feature in this book. It is one of the most important functions of Criminal Justice to play some part in the great task of Education for Citizenship.
