I don't know either. To me (an orthodox christian) the filioque seems like a post hoc justification for a schism that was already well underway if not inevitable. By 1054 what became the two churches had already clearly differentiated religious traditions, local saints, and liturgical practices with very little interchange between them, not to mention language, governance, and secular culture.

I have heard some fairly convincing (to a lay person) discussion between orthodox and catholic scholars that the filioque is potentially resolvable as a linguistic problem yes. But it's not worth really pursuing without a solution for the bigger issue of papal primacy. I don't know anyone who claims to have a viable path to reconciliation there. Plus, you know, the thousand years of mutual distrust and enmity.
