Eric Kaufmann's book "Shall the Religious Inherit the Earth? Demography and Politics in the Twenty-First Century" examines the impact of religious population growth in different parts of the world, especially in the West, Israel, and the Muslim world. Kaufmann argues that the demographic growth of fundamentalist groups is challenging trends toward secularization and individualism in the West, and that the rise of religious fundamentalism, driven by high birth rates and a strong sense of identity, is reshaping politics and societies around the world. The book examines different fundamentalist religious groups—such as the Haredi, the Amish, the Mormons, the Salafis, and the Muslim Brotherhood—and demonstrates how their demographic, political, and social strategies are shaping the future. Kaufmann highlights the importance of understanding demographic dynamics in predicting political and social trends, and argues that the rise of religious fundamentalism raises serious questions about the future of the West and the world.
