Happened across this compelling quote on the Wikipedia metanarrative page:
Although first used earlier in the 20th century, the term was brought into prominence by Jean-François Lyotard in 1979, with his claim that the postmodern was characterised precisely by a mistrust of the “grand narratives” (Progress, Enlightenment, Emancipation, Marxism) that had formed an essential part of modernity.
It’s compelling to me because it neatly characterizes conspiracy theory, in terms of its “mistrust of the grand narratives” as a central defining characteristic.
Its interesting to me especially because there’s an undercurrent of contemporary conspiracy theory which claims to attack post-modernism itself as one of the “grand narratives.” But upon reading the above, it set things back into perspective for me. Namely, that conspiracy theory, where it does purport to attack post-modernism, does so by completely embracing its tools and methods.
