Discourses on secularization is one of the most demanding academic endeavors in the study of Politics and International Relations (IR). There are numbers of arguments to support this statement. First, as an academic discipline, Politics and IR are subdivisions of Social Sciences which are developed in the West, and hence cannot easily be separated from secularistic worldview. Second, the secularization of Politics and IR has created a myriad of problems in the society especially among the Muslim communities. The Western political thought and tradition in the study of, especially, International Relations is conceivably passive, for it is only able to explain, predict or confirm numerous wars and injustice around the globe. This passivity explains why the Western society which is represented by the two extremes, of Capitalism (Western Europe) and Communism (Eastern Europe), cannot achieve a universal community that guarantees peace and equality for all mankind. Third, as the philosophical and practical imbalances that plagued the West-developed Political Science and International Relations are revealed, ways are now open for new breakthroughs and inventions. It is in this concern that the non-Western theory and paradigm of Politics and IR can be presented and studied comprehensively. This book concisely discusses discourses on Secularization of Politics and IR and endorses the three arguments above. It is expected that this book could serve as an initial milestone by which Islamization of Politics and IR may commence.
