Secularization refers to the societal shift toward emphasizing worldly concerns over religious ones, involving the separation of secular and religious spheres, the diminishing public influence of religion, or its transformation into a private matter. Authors such as Augustus J. Thébaud associated it with an increase in "mental anarchy," while George Wharton James recognized both its challenges and potential advantages for indigenous populations, the Church, and the State.
John Campbell Oman contrasted Europe’s secularization driven by rationalism with India’s continued fusion of religion and public life, and Chapman Cohen viewed secularism as a movement aimed at countering superstition and advancing education. These viewpoints highlight secularization as a complex process, one that neither universally eliminates religion nor fits into simple stories of decline.
