The author sees Gandhi, in his writings and his life, as offering the most profound and influential theory, philosophy, and engaged practices of ahimsa. Embracing Gandhi’s insightful critiques of modernity, the book sees his approach as a creative and challenging catalyst to rethink our positions today. As expressed in the book’s title, we live in a post-9/11 world that is defined by widespread physical, psychological, economic, political, cultural, religious, technological, and environmental violence and that is increasingly unsustainable. The author’s central claim is Gandhi’s writings, philosophy, and practices, when selectively appropriated and creatively reformulated and applied, are essential for formulating new positions that are more nonviolent and more sustainable. These provide resources and hope for dealing with our contemporary crises. Two central questions the author poses for the reader are the following: What would a Gandhi-informed, valuable but humanly limited swaraj technology look like and what would a Gandhi-informed, more egalitarian, interconnected, bottom-up, decentralized world of globalization look like? In response, through a collection of essays, the book focuses on key themes in Gandhi’s thought, such as violence and nonviolence, Absolute Truth and relative truth, ethical and spiritual living. Challenging us to consider nonviolent, moral, and truthful transformative alternatives today, the author moves through essays on Gandhi in the age of technology; Gandhi after 9/11 and 26/11 terrorism; Gandhi’s controversial views on the Bhagavad-Gita and Hind Swaraj; Gandhi and Vedanta; Gandhi on socialism; Gandhi and marginality, caste, class, race, and oppressed others.
