Social change remains as necessary as ever in the present world of under-developed economics. The ratio between incomes of the “highest” and the “lowest” – tenth of people – measured according to their consumption possibilities has increased, notwithstanding the efforts made to develop. Many schools of thought see no other way out of this terrible contrast than one of violence. Yet violence itself is making for much misery. Mahatma Gandhi has always non-violent social change. India got its political independence without violence. Gandhian thought was not of a passive nature; it d constitute a revolution in thinking. So it seems clear that his thought deserves being spread again. I am happy to recommend one such attempt – this book of Non-violence and Social Change, a product of Professor J.S. Mathur’s infatiguable work in the University of Allahabad.
