  In this paper we argue against the orthodox definition of quantum
entanglement which has been explicitly grounded on several "common sense"
(metaphysical) presuppositions and presents today serious formal and conceptual
drawbacks. This interpretation which some researchers in the field call
"minimal", has ended up creating a narrative according to which QM talks about
"small particles" represented by pure states (in general, superpositions) which
--each time someone attempts to observe what is going on-- suddenly "collapse"
to a single measurement outcome. After discussing the consequences of applying
'particle metaphysics' within the definition of entanglement we turn our
attention to two recent approaches which might offer an interesting way out of
this metaphysical conundrum. Both approaches concentrate their efforts in going
beyond the notion of 'system'. While the first, called device-independent
approach, proposes an operational anti-metaphysical scheme in which language
plays an essential role; the second approach, takes an essentially metaphysical
path which attempts to present a new non-classical representation grounded on
intensive relations which, in turn, imposes the need to reconsider the
definition and meaning of quantum entanglement.
