Philosopher Charles Taylor has spent a lifetime of careful study unpacking the meaning and development of secularism. One of the things he demonstrates in A Secular Age (2007) is that one of the most common assumptions about modern secularism is, in fact, so completely erroneous as to constitute a myth. Yet, it continues to be believed, and has assumed such mythic value that to question it can elicit surprise if not shock.
The assumption involved is what Taylor refers to as “subtraction stories.” The idea is that previous generations, as they became more enlightened and educated, shed unfashionable and increasingly untenable beliefs about demons, miracles, virgin births and other propositions that science had revealed to be dubious. This process of subtracting traditional and unproven beliefs allowed people to get back to a view of reality that was simply natural and obvious—and entirely secular. Taylor says that’s not the way it happened.
James K. A. Smith, in How (Not) to be Secular: Reading Charles Taylor (2014), defines it this way:
Subtraction stories Accounts that explain “the secular” as merely the subtraction of religious belief, as if the secular is what’s left over after we subtract superstition. In contrast, Taylor emphasizes that the secular is produced, not just distilled (p. 143)
Near the beginning of A Secular Age, Taylor puts the issue this way:
I will be making a continuing polemic against what I call “subtraction stories”. Concisely put, I mean by this stories of modernity in general, and secularity in particular, which explain them by human beings having lost, or sloughed off, or liberated themselves from certain earlier, confining horizons, or illusions, or limitations of knowledge. What emerges from this process—modernity or secularity—is to be understood in terms of underlying features of human nature which were there all along, but had been impeded by what is now set aside. Against this kind of story, I will steadily be arguing that Western modernity, including its secularity, is the fruit of new inventions, newly constructed self-understandings and related practices, and can’t be explained in terms of perennial features of human life. (p. 22)
Every believer will not need to work through the 850 pages of dense argument presented in A Secular Age. Only a few of us need to do that. I would, however, encourage Christians to work through the 143 pages of How (Not) to be Secular, because the ideas presented here, though seemingly abstract, actually touch on what it means to live in the secular world of advanced modernity.
