Chapter III EFFICACY AND LIMITATIONS OF LARGE- SCALE SOCIAL REFORM AMONG people who hold what are called * advanced .TX opinions* there is a widespread belief that the ends we all desire can best be achieved by manipulating the structure of society. They advocate, not a 'change of heart' for individuals, but the carrying through of certain large-scale political and, above all, economic reforms. Now, economic and political reform is a branch of what may be called preventive ethics. The aim of preventive ethics is to create social circumstances of such a nature that individuals will not be given opportunities for behaving in an undesirable, that is to say an excessively 'attached,* way. Among the petitions most frequently repeated by Christians is the prayer that they may not be led into temptation. The political and economic reformer aims at answering that prayer. He believes that man's environment can be so well organized, that the majority of temptations will never arise. In the perfect society, the individual will practise non-attachment, not because he will be deliberately and consciously non-attached, but because he will never be given the chance of attaching himself. There is, -it is obvious, much'truth in the reformer's contention. In England, for example, far fewer murders are committed now than were committed in the past. This reduction in the murder rate is due to a number of large-scale reforms— to legislation restricting the sale and forbidding the carry- ing of arms j to the development of an efficient legal system which provides prompt redress to the victims of outrage. 16
