Solitarism is the assumption that each person belongs to exactly one overriding group (a religion, civilization, or ethnicity) that defines them. It erases the many simultaneous affiliations everyone actually holds, such as nationality, profession, gender, class, language, politics, and tastes. Once a person is seen only as 'a Muslim' or 'a Hutu', their other loyalties stop counting as legitimate grounds for action.
Communitarian views hold that identity is simply found through one's community. Sen argues instead that people must reason about which of their many affiliations should take priority in a given context. That choice is constrained but real, and denying it strips people of responsibility and agency.
During the 1940s Hindu-Muslim riots, the young Sen saw Kader Mia, a Muslim day laborer, bleeding after being knifed by communal thugs. Kader had entered a hostile Hindu area because his family was hungry and he needed paid work. He was killed for his religion, yet the pressure that put him in danger was his economic identity as a poor worker, which shows how one imposed identity can obliterate a person's real circumstances.
The 'clash of civilizations' thesis sorts the world into blocs like 'Islamic', 'Western', and 'Hindu', and then treats conflict between them as natural. Sen shows these boxes are historically false, since reasoned debate, tolerance, and science grew in many regions, as with Akbar's interfaith dialogues and Ashoka's edicts. Seeing people through a civilizational grid is therefore a flawed act of classification before it is any kind of prediction.
Sectarian leaders turn ordinary people into killers by persuading them that one shared identity is their only one, and that it is under threat from another group. People who were neighbors, coworkers, and fellow citizens yesterday get redefined as enemies by skilled 'artisans of terror'. The solitarist illusion is therefore a tool that political entrepreneurs manufacture and exploit, not a spontaneous feeling.
Policies that sort citizens into separate faith communities and route them through religious leaders and faith schools produce 'plural monoculturalism'. This means several isolated cultures side by side, each confining its members, rather than real multiculturalism. Genuine multiculturalism protects each individual's freedom to choose among and combine cultural affiliations, rather than assigning people to the community of their birth.
