Aristotle saw poetry as positive

Aristotle, on the other hand, saw poetry as having a positive value: “It is a great thing, indeed, to make proper use of the poetic forms,… But the greatest thing by far is to be a master of metaphor” (Poetics 1459a); “ordinary words convey only what we know already ; it is from metaphor that we can best get hold of something fresh” (Rhetoric 1410b)
