A CRIME is an act forbidden by the law of the land and one which is considered sufficiently serious to warrant providing penalties for its commission. It does not necessarily follow that this act is either good or bad; the punishment follows for the violation of the law and not necessarily for any moral transgression. In this book, the author has endeavoured to present the latest scientific thought and investigation bearing upon the question of human conduct. He has tried to show that the laws that control human behaviour are as rigid and certain as those that control the physical world. Thus, if man actions are governed by natural law, the sooner it is recognized and understood the sooner will sane treatment be adopted in dealing with crime The sooner too will sensible and humane remedies be round for the treatment and cure of this most perplexing and painful manifestation of human behaviour.
