本研究擬從宗教現象學的角度探討先秦儒家的宗教性。本研究以維根斯坦的「家族相似性」作為描述「宗教」的理據，運用海德格的「形式指引」（“formal indication”）與呂格爾的「象徵主義」（symbolism）作為探討「宗教性」時的現象學方法，並以尼尼安‧斯馬特（Ninian Smart）的「宗教向度論」作為展開論證的參考架構。本研究透過討儒家之道、經典與傳統的內涵，而將《詩》、《書》、《易》、《論語》、《孟子》、《荀子》等典籍當作研究範圍與主要分析文本。 　　本研究指出：《詩》、《書》、《易》裡所反映的殷周初民思想為先秦儒家之宗教性的根源，於其中我們可窺見其宗教性的敘事與神話、經驗與情感向度、儀式與實踐以及社會與制度等向度。孔子則承繼了《詩》《書》《易》的宗教內涵，而予以哲理形塑與倫理轉化。孔子之後，作為代表著先秦儒家的內聖與外王之內部的分化發展的孟子與荀子，他們皆自詡為道統的接班人與宣揚者，並分別使得先秦儒家之宗教性的情感經驗向度得以深化、儀式制度向度得以開展。 / This study aims at investigating the religiosity of classical Confucianism from the perspective of phenomenology of religion. It takes Wittgenstein’s concept of “family resemblance” as the methodological guide for characterizing “religion” in general, and Martin Heidegger’s concept of “formal indication” as well as Paul Ricœur’s symbolism as the phenomenological tools in describing “religiosity” in particular. It also adopts Ninian Smart’s theory of dimensions of religion as the framework for unfolding its argument. Meanwhile, by way of discussing the Confucian ideas of “dao,” “classics” and “tradition,” this study delimits its intellectual journey and choses the Classic of Poetry, the Book of Documents, the Book of Changes, the Confucius’ Analects, the Mencius and the Xunzi as the main texts for its inquiry. This study indicates that the thoughts contained in the Classic of Poetry, the Book of Documents and the Book of Changes are the roots of the religiosity of classical Confucianism. They reflect the narrative and mythic, experiential and emotional, social and institutional dimensions of that religiosity. Then this study shows that it is later philosophically reshaped and ethically transformed by Confucius. Finally, this study argues that Mencius and Xunzi, who regard themselves as the apologists and propagandists of orthodox Confucianism, have explored the experiential and emotional dimension and developed the social and institutional dimension of classical Confucianism’s religiosity respectively.
