War makes life miserable for both the parties involved, the invader and the invaded. No war is fought without losing men and material, stripping off societal life and political order. Simultaneously it contributes to the progress of the society and preserves the liberty and honour of a state. From the Vedic period of India and the epic period of Greece, we have records of wars, and deliberations on the logic, philosophy, politics, ethics, strategies (pre- and post-war) of war, and the ways of reconstructing the war-ravaged societies, paving the way for drastic social and economic changes. This volume scans the Indian and Western views and approaches on war in the ancient and modern times. To understand the concept of war in ancient period, it analyses Rigveda, Manusmriti, Ramayana, Mahabharata and Arthasastra from the Indian parlance and the philosophies of Plato and Aristotle from the Western perspectives. It also makes an in-depth study on the war philosophies of modern Indian leaders like Mahatma Gandhi, Sri Aurobindo, Vinayak Damodar Savarkar and S. Radhakrishnan, and Western philosophers like John Locke, Immanuel Kant, Georg Friedrich Hegel and Bertrand Russell. The book also explains the nature of war, its socio-economic and political aspects, and how the moral and social ethical concepts are related pragmatically to the issue of war. The author echoes serious concerns about the ways by which the present-day global majors approach war.
