Brian Cutter vs Graham Oppy: Does Mind-Brain Harmony Point to God? · 2025
Cutter argues psychophysical harmony favors divine goodness; Oppy counters that identity theory and unresolved probability measures undermine the proposed evidential comparison.
Brian Cutter: 85 · Graham Oppy: 85. Scores assess the reasoning in this debate.
Graham Oppy vs Kenny Pearce: Is There a God? · 2022
Pearce develops theistic grounding and experiential arguments, while Oppy presses symmetrical naturalistic alternatives, epistemic calibration, and religious diversity as stronger comparative explanations.
Kenny Pearce: 84 · Graham Oppy: 88. Scores assess the reasoning in this debate.
Michael Huemer vs Graham Oppy: Do Souls Exist? · 2022
Huemer argues that irreducible mentality requires a surviving soul, while Oppy offers multiscale naturalism, brain dependence, and cosmological objections to that inference.
Michael Huemer: 76 · Graham Oppy: 84. Scores assess the reasoning in this debate.
Does Analytic Idealism Better Explain Reality? Bernardo Kastrup vs. Graham Oppy · 2021
Kastrup makes consciousness and qualitative experience the central explanatory test; Oppy narrowly prevails by clarifying pluralistic naturalism, identity, underdetermination, and balanced theory choice.
Bernardo Kastrup: 81 · Graham Oppy: 82. Scores assess the reasoning in this debate.
Philip Goff vs Graham Oppy: Is Finite Theism Preferable to Naturalism? · 2026
Goff’s finite God unifies purposive value and suffering through limited power; Oppy’s naturalism counters with simplicity, modal uncertainty, and evolutionary explanation, producing a tie.
