  In this paper we address the relativist-perspectival nature of the orthodox
definition of quantum entanglement in terms of preferred factorizations. We
also consider this aspect aspect within the generalized definition of
entanglement proposed by Barnum et al. [6, 7] in terms of preferred
observables. More specifically, we will discuss the non-separable relativism
implied by the orthodox definition of entanglement, the contextual relativism
implied by its generalization as well as some other serious problems presently
discussed within the specialized literature. In the second part of this work,
we address a recently proposed objective-invariant definition of entanglement
understood as the actual and potential coding of effective and intensive
relations [32]. Through the derivation of two theorems we will show explicitly
how this new objective definition of entanglement is able to escape both
non-separable relativism and contextual relativism. According to these
theorems, within this proposed relational definition, all possible subsets of
observables as well as all possible factorizations can be globally considered
as making reference to the same (potential) state of affairs. The conclusion is
that, unlike with the orthodox definitions, this new objective-relational
notion of entanglement is able to bypass relativism right from the start
opening the door to a realist understanding of quantum correlations.
