Using Neville's framing of ultimacies & ontology, the most coherent, while at the same time sweeping, accounts of the relationships between non/& in/determinacies have for me been those of Hegel, Peirce & Neville.
When taken on BYONihil terms, they can leave one knife's edge-poised between a nihilism vs panentheism, presenting them as nearly nonadjudicable equiplausibilities derived merely from competing descriptions of "nothing."
By nearly nonadjudicable I mean to acknowledge that they indeed are decidable, pragmatically so, which is to say using normative justifications like existential actionability.
That's why theism's been the default stance for humankind, preventing atheists from sallying forth w/stances defined on their own terms, requiring them to proceed over against theism. But, bring your own "nothing," & the coherence of Hegel & CSP will serve either stance well.
