Today economic modernisation and social change have separated people from traditional, local identities. Instead, religion provides a basis for identity, especially for Muslims, and as we are seeing in India in recent months, for Hindus. The confluence of these developments in North America, Europe, the Middle East and Asia is fuelling afresh the idea of a clash of civilisations. Huntington may be fashionable, but not quite as a visionary prophet; rather as a teller of cautionary tales. Yet there are enough reasons to challenge his catastrophic view of the world. There is no insulation between Islamic and secular modes of being. Multiculturalism is not a naive aspiration—it is the reality of our world. Since 13/11, Muslims of all backgrounds, ages and nationalities have come forward to express sympathy with France and opposition to what ISIS represents. It is a daily refutation of the idea that different faiths and cultures cannot live and work together. That alternative will only add to the violence. The world is not fighting terrorists. It’s battling an ideology that has been twisted to suit bad politics, one that is not targeting countries, but a way of life. No one can picture Paris without its bars and cafes, its parks and restaurants and its men and women laughing, loving and mingling—the Fraternite that makes this City of Lights so appealing, so romantic and so unique. The French way of life is to live and let live, liberal in every sense of the word. It is a concept and a city, worth defending against this monster made by violence.
