関係性の改善の哲学

Abstract This paper proposes the Philosophy of Relational Improvement as a meta-ethical framework that governs the conditions under which ethical judgments remain practically effective. Rather than presenting a new normative ethical theory intended to replace existing approaches, this study conceptualizes relational improvement as a highest-order ethical frame that structures the application of normative ethics themselves. Traditional ethical theories—such as utilitarianism, deontology, and virtue ethics—provide powerful tools for evaluating actions, outcomes, and character. However, in certain contexts, their application can rigidify or irreversibly sever human relationships, thereby undermining the continued practical relevance of ethical judgment itself. This paper reframes this problem not as a competition among ethical theories, but as an issue concerning the order and hierarchy in which ethical frameworks are applied. The Philosophy of Relational Improvement prioritizes the preservation and reactivation of relational contexts in which mutual deliberation remains possible. Within this framework, existing normative ethical theories function as subordinate structures responsible for concrete moral evaluation. The proposed framework neither negates nor relativizes justice, duty, or moral norms; rather, it identifies relational continuity as a precondition for their sustained practical efficacy. Furthermore, this paper argues that relational improvement can be understood as an integrative higher-order concept that accommodates the modern political values of liberty, equality, and fraternity without subordinating one to another. By focusing on the conditions of ethical applicability, the Philosophy of Relational Improvement offers a systematic approach to maintaining ethics as a living, functional practice within social relations.
