Even though the author of Dorian Gray preached aestheticism as the ultimate goal of arts, his work does not converge to that conclusion.
Oscar Wilde, along with other artists belonging to the movement, claimed to believe art is done for art's sake. That, behind books, pictures and music, there shouldn't be a deeper meaning, a lesson to be taught and learned, any political positioning to defend or attack. Art was, thus, only supposed to be beautiful.
However, Wilde's character Dorian finds himself sinking in life for his lack of moral. Concerned only about his own youth and beauty, Dorian is incapable of loving and connecting to another human being. Consequently, everyone around him suffers and he becomes a dark and lonely soul, whose sins and real age are apparent in a picture of him painted by a friend.
Let me start from the beginning - just a little bit, basically Mr. Ewell was angry at Atticus for what he'd said at trial about his daughter - that in the end he decided to attack Jem and Scout in the woods.
BUT, Jem heroically got Scout out of the way - risking his own life. To make matters worse, though, poor Jem did end up with a broken arm.
I hope all is well and you pass! (: Good luck, rockstar! If you have any follow up questions, let me know! This book is still fairly fresh in my mind! (:
It is ironical because because Ozmandias considered himself to be the strongest and most powerful, he also thought that he would be remembered forever will all his great works.
