&nbspThis book is about legality in its relation with morality. It is to explore dialectical dynamics in-between the two subject matters, i.e., legality and morality. It is because, in reality, the ethical foundation of legality is getting weaker and more ineffectual. That is why the authority of the law is getting weaker and less effective, as time goes on. That is consequently why there are more violence and crimes in American society, if not in the entire global community. &nbspThis book is by no means to teach you the law. Legality has its own rich history and tradition, formal and informal conventions, and profound and diverse theories and doctrines. This book is simply geared to highlight the ethical dimension in the nature and function of the law. In brief, it is to "ethicalize" the law in its legislation, interpretation, and execution. &nbspInstead of discussing in detailed theories and doctrines of the law being entertained by its complexities and diversities, this book is to investigate philosophically major themes of the law, mainly in order to reveal their inherent connections with ethics and ultimately to emphasize the crucial necessity of ethics in legality. Unless we radically increase the ethical implication in legality, the humanity may not be able to entertain the twenty-second century.
