The secular Enlightenment replaced one conceptual binary rather than ending binary thinking

Evidence

Some modern commentators have observed that statements such as Fontenelle’s signaled a mutation of the older opposition between sacred and profane into a new opposition between imagination and reason, principles that inaugurate the secular Enlightenment. This change, they suggest, should be seen as the replacement of a religious hegemony by a secular one. But I think what we have here is something more complicated. — Talal Asad, Formations of the Secular, 128

Categorization

• XREF: Directly feeds the vaulted Cooper/Asad thread: the ‘secular’ isn’t a neutral successor to religion but installs its own regulating Reason. Echoes how secular modernity quietly privileges Christian-normed categories.
• QUESTION: What exactly is the ‘more complicated’ thing Asad sees in the sacred/profane to imagination/reason shift? Worth chasing into the next passages.
