NATURE, HISTORY, AND ETHICS 409 



men were selected whose conscience was pricked, not 

 only if they committed murder, but also if they were 

 guilty of theft or any other crime against the community. 

 That they were able to act at all against the instinct was 

 due to the fact that selection favoured not only the more

 " bad " often mean something quite different from what
