Quote #7
"I don't know, I'm making this up as I go!"
The fool is the man who thinks himself wise, while the wise man knows that he is a fool. If Indy gains wisdom on his adventures (and what self-respecting Campbellian hero doesn't?), then this must be the first real sign of it: the fact that he doesn't have the first idea what he's doing.
Quote #8
"I am uncomfortable with the thought of this… Jewish ritual. Are you sure it's necessary?"
If Dietrich had done any reading, he'd know that you have to use a Jewish ritual to open the Ark, and you'd better have your karmic ducks in a row when you do. His ignorance sets him apart from Indy and Belloq, making him just a thug in a uniform rather than a worthy adversary. Nazis had a lot of "scientific" knowledge based on racist and hate-based beliefs.
Quote #9
"Marion, don't look at it! Shut your eyes Marion; don't look at it no matter what happens!"
In a weird way, this echoes Indy's earlier "I'm making this up as I go" line. He's wise enough to understand when knowledge has to take a back seat—he has to close his eyes rather than see what the Ark has to show him—and has the humility (wisdom) to accept it rather than fighting it. It's God after all; you kind of have to go with the flow.
