Morteza Niami

This philosophy presents the Niami Model of Sufficiency-Oriented Responsible Suspension, a multi-level normative framework for ethical decision-making under conditions of value conflict and epistemic uncertainty. Grounded in the concept of the limited moral subject—an agent embedded in psychological, epistemic, and social constraints—the model introduces responsible suspension as a purposive and bounded deferral mechanism that enables morally sufficient action where perfectionist ideals prove unattainable. The framework operates across five interconnected levels: subjective, intersubjective, institutional, epistemic, and normative. At the intersubjective level, it integrates contractarian ethics' criterion of "reasonable rejectability" with Habermasian discourse theory, ensuring decisions emerge from free, non-coercive dialogue with stakeholders. Institutionally, suspension is embedded within professional ethics committees and participatory procedures, linking individual judgment to collective accountability. Epistemically, the model demands transparency, criticizability, and active reduction of ignorance through assessable reason-giving. Responsible suspension is strictly defined by three conditions: necessity of reflection, provision of assessable reasons, and placement within a revisable process. Its initiation requires genuine value conflict, substantive epistemic uncertainty, and stakeholder asymmetry. Termination occurs upon information sufficiency, exhaustion of reasonable reflection, or stakeholder convergence. Post-suspension action must satisfy three thresholds: public non-rejectability, minimization of unjustified harm, and accountable sustainability. The Niami Model thus transforms ethics from an abstract, idealized system into a practical, revisable architecture that distributes moral difficulty across transparent, accountable structures. It offers a coherent framework for ethical crisis assessment, policy design, and governance of complex uncertainty without claiming final solutions, but rather demonstrating the possibility of legitimate, defensible, and sustainable ethical action when certainty and coherence are exceptions rather than rules.
