How does Syme’s work reflect or emphasize what readers have already learned about oceania?

Syme is a philologist working on the Eleventh Edition of the Newspeak Dictionary. Although Winston dislikes Syme, he enjoys having somewhat interesting conversations with him. Winston notices that Syme, although a devoted Party member, is too smart and too vocal for his own good. He predicts Syme will be vaporized and is proven correct when he suddenly disappears. Syme represents systematic destruction of the old world. Ironically it is his zeal for this destruction that leads to his own demise.
