Julia seems to be a very insightful person who has many philosophies.
All Julia seems to talk about though is he sexuality. Sex is her tool
to beat Big Brother, and to manipulate the system of the Inner Party.
As Winston says "everything came back to her own sexuality." She also
seemed to grasp the inner meaning of the Party's sexual puritanism,
though Winston has not been able to do that. So, Julia's philosophies
about the Party's sexual puritanism is what you have sex you use up
energy. She says after you have sex you feel happy and do not care
about anything else. The Party does not want you to feel like that.
She says the Party wants you to be bursting with enery all the time.
That energy can go to things like marching and cheering and waving
flags. She says that is simply sex gone sour. Julia thinks if you are
happy inside, why would you be excited because of Big Brother, the
Three-Year Plans, Two Minuets Hate, and "all the rest of their bloody
rot."
