Journalists should be aware that 2023 turns out to be big for the much-discussed “secularization theory” framed by the 19th Century founders of sociology.

The nub of theory claims that economically advancing societies with improved education inevitably become more secular, largely because modern science explains matters formerly left to the religious realm.

The NYU Press states that its 2023 release “Beyond Doubt: The Secularization of Society” demonstrates “definitively that the secularization thesis is correct, and religion is losing its grip on societies worldwide.” Steve Bruce of the University of Aberdeen, author of the classic “Secularization: In Defence of an Unfashionable Theory” (Oxford, 2011), blurbs that this new title “will be the defining text on the undeniable proof” that supports the concept.

The three co-authors of “Beyond Doubt,” all experts, are Ryan Cragun (University of Tampa), Isabella Kasselstrand (also at Aberdeen), and Phil Zuckerman (founder of Pitzer College’s Secular Studies program). They take on such noted U.S. critics of the theory as Christian Smith, Rodney Stark, and the late Peter Berger. Though such theorizing has focused on the West, this book (which The Guy has yet to read) is distinctive in drawing together elaborate data from several dozen varied countries.

The United States, however, has long been a serious problem for the theory. It’s an educationally, economically and scientifically advanced culture that has persisted with a far more devout population than in, say, Western Europe or Canada.

Yes, but now, as the news media frequently remind us, 21st Century America has experienced a rapid and substantial increase in “nones” who tell pollsters they have no religious identity and are either atheist, agnostic, or — by far the largest category — “nothing in particular.” Their ranks have nearly doubled since 2007. And there other signs of sagging religious vitality.

It seems secularization has finally triumphed even in the United States.
