Integration by Constraints: A Method for Disciplined Inquiry Across Divergent Frameworks

Abstract: Divergent frameworks rarely agree about what is true. They can agree about what any adequate account must explain. Once that agreement is secured, disciplined comparison becomes possible — exposing hidden commitments, distinguishing regularities from interpretations, and letting the force of what any framework must handle do its work. Integration by Constraints articulates this method, the epistemic foundation of the Return to Consciousness project. Constraint-based reasoning asks not which worldview is correct? but what conditions must any explanation satisfy, regardless of its ontological commitments? The essay defines what constraints are, distinguishes them from commitments, draws the critical difference between phenomenological regularities (constraint candidates) and metaphysical interpretations (not constraints), and names four criteria for constraint-candidacy: robustness across methods, recurrence across contexts, resistance to eliminative explanation, and cost of exclusion. The criteria require judgment in application, and the essay is explicit about this. The result is a method applicable across quantum foundations, consciousness studies, developmental biology, AI alignment, and contemplative investigation — disciplined comparison rather than verdicts, whose ambition is the discipline, not the outcome.
