Here's another dialogue from the movie 'The Shawshank Redemption'... it is all about how human being becomes conditioned... institutionalised. The dialogue here is in the context of a prison (long term). But it is not very much different from how we as religious get 'institutionalised'. (Thanks to Chris for pointing this out to me!).
RED: Heywood, enough. Ain't nothing wrong with Brooksie. He's just institutionalized, that's all.
HEYWOOD: Institutionalized, my ass.
RED: Man's been here fifty years. This place is all he knows. In here, he's an important man, an educated man. A librarian. Out there, he's nothing but a used-up old con with arthritis in both hands. Couldn't even get a library card if he applied. You see what I'm saying?
FLOYD: Red, I do believe you're talking out of your ass.
RED: Believe what you want. These walls are funny. First you hate 'em, then you get used to 'em. After long enough, you get so you depend on 'em. That's "institutionalized."
JIGGER: Shit. I could never get that way.
ERNIE: Say that when you been inside as long as Brooks has.
RED: Goddamn right. They send you here for life, and that's just what they take. Part that counts, anyway.
