Does "but need not be so" mean "but need not be generally acceptedto be true (because an axiom is self-evident"?

I think "generally" means " in most cases but not all cases".
So "need not be so" means "there are exceptions".

I take 'need not be so' to mean 'need not be true' there.

Which explanation is more accurate? I noticed that Rover_KE liked both answers. I am inclined to the last one.

"But need not be so" means the statement or principle can be false and still be an axiom. "Generally accepted" normally means that almost everyone accepts it.

Not a teacher.
