This paper deals with metaphysical nonviolence foundation, as a necessary support for more effective social change. First, this paper intends to elucidate how Mahatma Gandhi’s metaphysics of nonviolence influenced and contributed to the development of 21st century legitimate social change. Gandhi`s metaphysics is understood as a maximal and universal rejection of violence and war. His influence on Western thought is most often represented. Recent history suggests that use of nonviolence as a strategy has the power to even overthrow dictators. Gandhi’s influence in terms of political strategies that do not need a metaphysical or religious foundation, portray how pacifism can be exercised in even the most culturally restricted contexts. Furthermore, an examination of Gandhi’s metaphysical foundation through his nonviolent philosophy and practice illuminates striking links with the modern theories of revolutions. The methodology will mainly be based on archival research and follow a narrative analysis form. Hence this paper will argue that the use of metaphysics of nonviolence can achieve legitimate social change through pacifism in the 21st century.
