What's the difference between not needing to make any more adjustments and not being able to make any more adjustments?
Immense. It is the same as not needing to add air to your tires and not being able to.
You're over-generalizing. Some religious minds refuse to adjust some faulty premises. "The" religious mind just doesn't stop when it runs out of verifiable premises.
The difference begins when we stop verifying the premises.
