In Literay Criticism, what is the position or stand of Aristotle, Horace, Longinus and I.A. Richards?

Answer 1

The question you propose would involve a dissertation to answer, I'm afraid.

Aristotle's Poetics, Longinus' On the Sublime, Horace's Ars Poetica, and Richards' Principles of Literary Criticism aren't really texts that one can distill down to a single position or stand without being extremely reductive.

And that assumes that one could boil down their critical opinions from those books alone, which is probably unwise to begin with.

Answer 2

You are in luck, the information you want is right here:
