Can I believe you?

Winston the main is the main character in the book 1984. He is seen at first as a very intelligent man who takes a great deal in the analysis in his opinion. But once he talks about the process of doublethink fear immediately begins to creep into your mind. You begin to wonder if he is under the process of doublethink himself. Even his memories start to sound like hazy picture which can change on the dime. Now when I hear him talk I wonder is he lying to me. In the end the question isn't is he lying to me, but what if he is lying to himself and doesn't know it. This is actually the first time I have read a story where the narrator is partially unreliable it was always he was a complete liar or he was completely truthful. This partial liar really turns the story into a true mystery of what is true and what isn't.
