Book excerpt: First published in 1960, International Conflict in the Twentieth Century considers how to solve the problem of human relations for external affairs. Stepping back from the more common focus on "current affairs", the book explores in detail the processes and patterns of history, the principles that underlie foreign policy, the ethical issues involved in international affairs, and the role of Christianity in a time of global revolution. In doing so, it covers a variety of topics including morality, scientific approaches to politics, lessons from history, and human nature. International Conflict in the Twentieth Century will appeal to those with an interest in religion and politics, religious philosophy, and religious and political history.
