i know nothing about Tyler
but i know that i come down hard on Derek because he hasn't made the transition from stage six to seven.
Mayflow, you are still negotiating the passage from stage one to two.
you are filled with messages some wise woman has wispered to you long ago,
but you wander aimlessley in the Valley of Flowers.
I congradatulate you!
Oh so few make it to Nandan Kanan.
Will you also die without a purpose of fire?
In the book (and later movie) Fight Club, Tyler is the protagonist's shadow. We never know the name of the protagonist for sure but are left assuming his name is Jack. Fight Club has to do with corporate america, how men are demasculinized in society, has some other issues with religion mixed into everything. The protagonist will interact with Tyler, but he doesn't 'realize' Tyler is him until much later on. The shadow becomes an alter ego of his, or better said a Jeckyll/Hyde.
There are 'rules' to fight club but the main one is "The First Rule of Fight Club is you don't talk about fight club." That's a message about keeping things within, that you keep things within you and not bring them out, how they become destructive. He also has an addiction to self-help groups. Marla (his anima) ends up attending, which the book doesn't directly indicate she is a projection, but you're left wondering it, esp. since she begins attending the self-help groups, and then they begin to 'alternate' when 'she' will attend a group, and he will attend a group. She's sick and dying but its because his shadow is also, literally, effing with her. He never remembers having sex with her because the shadow is doing it. His alter ego. But it really represents in an interesting twist, the corrpution of the shekinah.
In the book at the end he ends up killing his boss and blowing up buildings, in Project Mayhem. But he also finds the only way to get rid of Tyler is to shoot himself, and he lives. In the book it ends different from the movie (movie ends stupid), and he's locked in a mental ward.
