The phrase "of the world" indicates that there is information which exists independent of any given observer experiencing that information.
The argument often goes that what ever is that information it must first be processed by a given mind before that given mind can verify the existence of that information.
Again suggesting that all information a mind encounters is self generated is not a logically consistent foundation for metaphysics because the self recursion leads to an ill defined infinite regress.
If the term self is not logically distinct from not self by definition then it is not clear what the term self means.
And if we do not first assume that the self is distinct from the not self then there is an infinite regress in the steps to prove the proposition that the self can verify selfness by consulting the self, which consults the self, and so and so forth ad infinitum.
Once again I think people conflate the notion that information that exists independent of the self with the problem of that information existence must be processed before the existence of that information is verified by a particular mind.
We can use logic to demonstrate that there is information which exists independently however.
If there were no such information which existed independently of the mind then we would never learn new things or discover that our beliefs were wrong.
There is no way to account for this phenomena if the term self is not distinct from term not self.
For me I see no great controversy to suggest that metaphysics be founded on the notion that there is a distinction of self and not self.
Once having done this, then by definition not self exists independently of self and there is nothing interesting to debate.
Simply put, that information which you do not know and which your mind has not processed is independent of self in every way.
That you can process such information and that the information can be made aware to the self is not the equivalent of therefor you can conclude that such information was never independent of the mind.
So there is no big metaphysical controversy at all.
The whole debate to me is not philosophically interesting considering the dilemma at hand.
The term self can be ill defined and ambiguous such that there now exists a metaphysical dilemma.
Or, the simple solution, define the term self such that it is logically distinct and exists independently from the term not self.
