Definition

Secularization is the long-term historical process by which religious institutions, belief and practice have played a declining public, social and political role in many Western societies, examined by sociologists and philosophers as a multi-causal, long-developing phenomenon rather than a single event.

Historical Origin

Sociologist Max Weber’s early-20th-century work examined religion’s changing relationship to modern economic and social life, while philosopher Charles Taylor’s A Secular Age (2007) offered an influential, more recent account arguing that secularization is best understood as a centuries-long transformation in the very conditions and possibilities of belief itself, rooted in developments extending back to the late medieval and early modern periods, rather than a sudden mid-20th-century cultural rupture.

How Supporters Understood It

Some theorists of secularization have framed the process as a natural and largely positive consequence of scientific and social modernization, in which religious explanation gradually gives way to secular, rational and scientific understanding of natural and social phenomena.

Criticisms

Taylor’s own account explicitly criticizes simpler “subtraction story” versions of secularization theory — which treat it as religion simply being subtracted away as science advances — arguing instead for a more complex transformation in the entire framework of possible belief and unbelief available to people in different historical periods.

Historical Uses

Secularization is examined throughout sociology of religion research studying declining religious affiliation, attendance and self-identification across many, though not all, Western societies over the 20th and 21st centuries, with significant variation in pace and extent across different countries.

Documented Consequences

Researchers have studied documented associations between secularization and various social changes, including changing marriage and family patterns and civic participation, addressed further in this archive’s Society & Family collection, while treating the causal relationships involved as a matter of continued, active debate.

Misuse or Distortion of the Idea

Secularization theory in its simpler, older forms predicted religion’s near-total disappearance in modernizing societies, a prediction subsequent research has found does not hold uniformly — religious belief and practice remain strong in many parts of the world and have shown resilience or resurgence in specific contexts, complicating any simple linear secularization narrative.

Counterarguments

Sociologists of religion continue to debate secularization theory’s scope and universality, with some scholars proposing alternative frameworks (such as religious market or pluralism theories) to explain the uneven, non-linear pattern of religious change actually observed across different societies.
