In search of sources for quotes - (high concept dead-end thread)

[swag]

I remember this quote from a German film I saw in 1982, but I don't remember the name of the film. Maybe something about a "night inspector" in the title of the film. The line:

"The philistine is always right; he only errs in his suppositions."

Of course this was what the subtitle said, and may bear little relation to what the actor said.

Anybody know the name of the film?.

Also, quotes that I have been unable to verify in print. Anybody have a source for any of these (or for anything like them)? Thanks in advance.
