What is fascinating in the Bull's book titled the Anarchical Society: A Study Order in World Politics is that this book is undoubtedly one of the ways in which the field of interdisciplinary discussion and combined theories of other profits have provided. Contrary to what many may claim that his work is a classic book today that cannot be found in relatively contemporary complex theories, his book remains still, to a good extent, as a major study in the field of international order. In the first section, I tried to present and explain his arguments and his position in the field of international politics by placing his work in his own position. In the following section, an arrangement of his book has been presented in terms of conceptual framework. Then critics of his work have been discussed. In conclusion, this study argues that Hedley Bull's approach to the book of anarchic society is a blend and cannot be construed as neo-realism, neoliberalism, historical sociology, and evolutionism.
