First published in 1929, this book explores the crucial, ethical question of the objects and the justification of punishment. Dr. A. C. Ewing considers both the retributive theory and the deterrent theory on the subject whilst remaining commendably unprejudiced. The book examines the views which emphasize the reformation of the offender and the education of the community as objects of punishment. It also deals with a theory of reward as a compliment to a theory of punishment.Dr. Ewing’s treatment of the topics is philosophical yet he takes in to account the practical considerations that should determine the nature and the amount of the punishment to be inflicted in different types of cases. This book will be of great interest to students of philosophy, teachers and those who are interested in the concrete problems of punishment by the state. It is an original contribution to the study of a subject of great theoretical and practical importance.
