I’m arguing they’re minds of unknowable foreignness to our own. We fill in the gaps because the text per se has meaning. If anything, we give those minds meaning through the text, not the other way around.
We impute “the thoughts that produced” those writings. One can just as easily contemplate the method through which human writing got distilled into a matrix of numbers that produced a particular output in response to a prompt.
(I’ve absolutely read works without a care in the world for the author.)
