The statement is long and rambling -- it seems he's mocking Charlie's recent ramblings. Lorre says, "I believe that consciousness creates the illusion of individualism, the false feeling of being separate." Translation: Charlie may think he's blazing his own path but he's still on the well-traveled trail of life.
Lorre goes on: "I further believe that this existential misunderstanding is the prime motivating force for the neurotic compulsion to blot out consciousness." Translation: Charlie is living in a dream world.
There are other gems, but Lorre ends by writing, "The Fall from Grace is, in fact, a Sprint from Grace. Or perhaps more accurately, Screw Grace, I am so outta here!"
As for writing, "I am so outta here!" could be Lorre talking or it could be what Lorre thinks Charlie is saying.
The more we think about it, it seems he's referring to Charlie, but either way, what really seems "outta here" is "Two and a Half Men."
