@Grimlock,
I am not so sure that given N's position that the world is always interpreted, that he would accept the thesis that truth could be "objective." Indeed, isn't his position that concepts are, in some sense, a necessary way we falsify the complexity of the "dancing chaos" with which we are faced?
In the first Part of "Truth and Lie" he writes:
"Every concept originates through equating the unequal. As certainly as no single leaf is exactly equal to any other, so certain is it that the concept "leaf" has been formed through an arbitrary omission of these individual differences...through a forgetting of the differentiating qualities, and this concept now awakens the notion that in nature these is, besides the leaves, a something called the "leaf"..." (Wilcox translation).

If N. rejects the Kantian notion of thing-in-itself (see especially FW 354, and compare with MA9 orJ11), he also, it seems, rejects the possibility of any sort of objective reality in a
transcendental sense, or at least that it is knowable.
What is the last phase or step of the development of our understanding of the world? N. answers this in Chapter IV of G :
"6. The true world---we have abolished. What world has remained? The apparent one perhaps? But no!
With the true world we have also abolished the apparent one.
(Noon; moment of the briefest shadow; end of the longest error; high point of humanity; INCIPIT ZARATHUSTRA.)"
