五井蘭洲《易》學及其意義

The Meaning of Goi Ranshu’s Works about I-Ching

本文以日本江戶時代大阪地區懷德堂學派早期的重要儒者五井蘭洲（1697－1762）為探討對象，根據其《易》類講義作品與其他文稿，觀察箇中的《易》學相關表現及意義。本文首先指出，蘭洲的《易》學基本立場重視日用教化，以朱子學為主，但亦有不採朱熹之說的表現。接著本文說明《周易》是蘭洲論性時的主要理論資源之一，特別受到他的重視，在他對其他學派的批判中也扮演重要角色。最後本文認為，蘭洲《易》學相關表現的意義，其一在於呈現日本朱子學者在江戶時代中期面對學派競爭時，利用《周易》奪回話語權的作法，有助於使人了解《周易》在日本朱子學發展中的作用；其二在於顯現積極的教育意義，提供超越地域與國籍的東亞精神共同基礎。
