The argument that Sen makes is complex and I will not attempt to recap them here. But as a pointer, I’ll just mention that this talk is based on his book “Identities and Violence”. Sen questions the notion of Clash of civilisation by Samuel Huntington from different dimensions. He questions if any group of people can be neatly identified as a “civilization”, if animosity has to be the basis of difference and if Huntington’s identification of charecteristics of Western or Islamic civilisation are defendable.
Given Sen’s background he draws heavily from Indian history. But he also makes referneces to Arab world, Chinese history and annecdotes from other places in the world. Sen argues that each of us has multiple identities and commitments and makes a powerful case for a peaceful coexistance of diverse people.
