Demand for recognition of one’s identity is a master concept that unifies much of what is going on in world politics today. The universal recognition on which liberal democracy is based has been increasingly challenged by narrower forms of recognition based on nation, religion, sect, race, ethnicity, or gender, which have resulted in anti-immigrant populism, the upsurge of politicized Islam, the fractious “identity liberalism” of college campuses, and the emergence of white nationalism. Populist nationalism, said to be rooted in economic motivation, actually springs from the demand for recognition and therefore cannot simply be satisfied by economic means. The demand for identity cannot be transcended; we must begin to shape identity in a way that supports rather than undermines democracy. Identity is an urgent and necessary book―a sharp warning that unless we forge a universal understanding of human dignity, we will doom ourselves to continuing conflict.
