ネガティブ・ケイパビリティの認知科学的再構成：量子ゼノン効果の構造的メタファーに基づく理論的展望

抄録

This article offers a theoretical reconceptualization of negative capability (NC), understood as the capacity to remain with indeterminacy and suspend premature closure, within a cognitive scientific framework. While NC has traditionally been discussed in poetic and clinical contexts, the argument situates it in relation to indeterminacy and introduces the Quantum Zeno effect (QZE) as a structural model for describing the interplay between observation and state transitions. NC is characterized here as a metacognitive capacity that modulates transitions between cognitive states through the frequency and timing of observation or evaluation. By articulating the theoretical intersections among NC, indeterminacy, and QZE, the article recasts NC as a form of cognitive tolerance of, and regulatory control over, undecided states under indeterminacy, shaped by temporal and attentional dynamics. This framework illuminates how the mind can sustain ambiguity, delay commitment, and reorganize meaning over time, and it points toward future directions for modeling, operationalization, and empirical investigation of NC within cognitive science.
