This subject often comes up indirectly during discussions.
I’m interested in what people think of the claim that modern secularism is little more than Christianity without God. Many here will probably be familiar Tom Holland’s popular version of this notion wherein he argues that to a significant degree modern Western moral assumptions still come out of a Christian framework, even if people no longer believe in it explicitly. Progressives imagine we have moved beyond superstition but our foundations remained rooted in tradition.
One related and useful place to start might be with Alasdair MacIntyre, who makes a connected but slightly different point. He argues that modern secular and liberal moral language has become fragmented. While we still use words like “rights,” “justice,” and “freedom,” we’ve lost the shared background (e.g., Aristotelian or Christian ideas of telos, or human purpose) that once gave those terms a more stable meaning and normative structure. Without that shared framework, moral debate often turns into muddy disagreement with no clear resolution.
For example, we treat human rights as obvious and self-justifying, yet we often disagree deeply about what, if anything, actually grounds them, or how to weigh them when they come into conflict with other claims or interests. Or in debates about identity, harm, and issues like free speech or abortion, we often seem to end up with competing intuitions rather than agreement on underlying principles. Should be added here that MacIntyre’s point isn’t that we ought to go back to Christianity, but that modern liberal morality may still be relying on older moral structures it no longer fully acknowledges or can properly justify. I’m reminded of Nietzsche’s quip (I’m paraphrasing) that if you believe in grammar, you’re a theist.
So I’m curious how others respond to this framing, whether it’s correct and to what extent it matters. Is secularism best understood as a kind of diluted continuation of Christianity, or has it drawn on broader sources and developed its own independent coherence? Conversely, could this thesis just be a sophisticated form of reactionary thinking, capturing a partial truth while seeking to restore the authority of tradition by framing secular morality as derivative and groundless?
