Moral And Ethical Nature In Confucian Liang-Zhi And Islamic Fitra: Comparative Perspectives On Innate Morality, Yanrong Shi Aug 2025

Moral And Ethical Nature In Confucian Liang-Zhi And Islamic Fitra: Comparative Perspectives On Innate Morality, Yanrong Shi

Comparative Philosophy

This article offers a comparative philosophical analysis of Confucian liang-zhi (innate moral knowledge) and Islamic fitra(primordial nature), focusing on their accounts of innate morality and moral epistemology. Drawing on classical Confucian sources—especially the praxis-oriented interpretation of Wang Yangming—and foundational Islamic texts and commentary, the study demonstrates that both traditions posit an inborn moral faculty grounding ethical universality and responsibility. Wang Yangming’s liang-zhi is conceived as an innate moral principle that, under the imperative of zhi (to actualize or extend), is continually activated through moral practice. In parallel, fitra is understood as a God-given orientation to truth, cultivated and safeguarded through …


How Theravāda Buddhism Enriches The Language Of Thought Hypothesis: Beyond Syntax, Juanjuan Cheng, Sumanasara Sandamadulle Aug 2025

How Theravāda Buddhism Enriches The Language Of Thought Hypothesis: Beyond Syntax, Juanjuan Cheng, Sumanasara Sandamadulle

Comparative Philosophy

The Language of Thought Hypothesis (LOTH) posits that mental states operate through a language-like representational system physically implemented in the brain. However, this purely symbolic approach faces a significant limitation: certain mental phenomena—such as intuitions, emotions, and intentions—lack the syntactically compositional structure required by LOTH and therefore cannot be adequately explained within its symbolic framework. To address this theoretical challenge, we turn to Theravāda Buddhism (TB), an early Buddhist tradition that integrates rigorous philosophical inquiry with meditative practice. Remarkably, TB began to prefigure a solution to LOTH’s limitations over 2,300 years ago. Although LOTH and TB differ …
