Quote 10
"I know, now, that when one loses one's good looks, whatever they may be, one loses everything. Your picture has taught me that. Lord Henry Wotton is perfectly right. Youth is the only thing worth having. When I find that I am growing old, I shall kill myself."
Hallward turned pale and caught his hand. "Dorian! Dorian!" he cried, "don't talk like that. I have never had such a friend as you, and I shall never have such another. You are not jealous of material things, are you? -- you who are finer than any of them!"
"I am jealous of everything whose beauty does not die. I am jealous of the portrait you have painted of me. Why should it keep what I must lose? Every moment that passes takes something from me and gives something to it. Oh, if it were only the other way! If the picture could change, and I could be always what I am now! Why did you paint it? It will mock me some day -- mock me horribly!" The hot tears welled into his eyes; he tore his hand away and, flinging himself on the divan, he buried his face in the cushions, as though he was praying. (2.27-29)
Dorian is quickly won over by Lord Henry's argument, and he takes the implications of his inevitable aging really hard. We do have to wonder if this belief wasn't hiding somewhere down deep within Dorian himself – perhaps Lord Henry only helped it emerge.
Quote 11
For there would be a real pleasure in watching it. He would be able to follow his mind into its secret places. This portrait would be to him the most magical of mirrors. As it had revealed to him his own body, so it would reveal to him his own soul. And when winter came upon it, he would still be standing where spring trembles on the verge of summer. When the blood crept from its face, and left behind a pallid mask of chalk with leaden eyes, he would keep the glamour of boyhood. Not one blossom of his loveliness would ever fade. Not one pulse of his life would ever weaken. Like the gods of the Greeks, he would be strong, and fleet, and joyous. What did it matter what happened to the coloured image on the canvas? He would be safe. That was everything. (8.25)
Dorian's eternal youth seems assured now, and it allows him to relax. We can see just how warped his perspective is from this moment – he values youth and beauty above the health of his soul, and even thinks he'll take pleasure in watching the latter crumble.
Quote 12
He had the key, and no one else could enter it. Beneath its purple pall, the face painted on the canvas could grow bestial, sodden, and unclean. What did it matter? No one could see it. He himself would not see it. Why should he watch the hideous corruption of his soul? He kept his youth -- that was enough. And, besides, might not his nature grow finer, after all? There was no reason that the future should be so full of shame. Some love might come across his life, and purify him, and shield him from those sins that seemed to be already stirring in spirit and in flesh -- those curious unpictured sins whose very mystery lent them their subtlety and their charm. Perhaps, some day, the cruel look would have passed away from the scarlet sensitive mouth, and he might show to the world Basil Hallward's masterpiece. (10.13)
For a moment, Dorian feels the optimism that comes with the prospect of eternal youth – not only does he get to remain beautiful, he also has infinite time to change and improve himself. Unfortunately, this moment of hope doesn't last.
