Aristotle studied at Plato's Academy in Athens, which brings continuity from Socrates -> Plato -> Aristotle.
Plato:
'And when someone honors beauty more than virtue, this constitutes nothing other than a real and thorough dishonoring of the soul'
/ Plato, Laws, Book B, 727d.
Socrates and Plato held an often times contemptful view of the poet or artist, expressed at several occasions in Plato's Republic.
This is likely because the artist was viewed as an imitator. Reality is of course of higher value than any imitation. Add to this that Socrates was ridiculed by contemporary poets.
Aristotle:
'What aims at reality is better than what aims at appearance'.
/ Aristotle, Rhetoric, Book I, 1365-b.
From this we can see a clear difference between Plato and Aristotle. Plato is mainly concerned with ethics, whereas Aristotle is more analytical in regards to substance. Aristotle also values ethics highly, but he is interested in studying matters deeper.
