在禮學詮釋傳統中，類推思維具有重要作用。前人指出的重要詮釋、運用禮書之法，包括「以例釋禮」、「推致」、「約」等，皆屬類推思維。本文提出的「情理類推」，亦為類推詮釋法，並主要集中在《儀禮．喪服》及相關文獻的詮釋與運用上。本文首先界定「類推」一詞的意義，並探尋「情理類推」的禮學淵源。其次，略論「以例釋禮」等三種方法，一則以見類推思維在禮學中受到廣泛運用，二則彰明「情理類推」與三者相異處。第三部分由經典內容、實際運用及經典研究等方面，以實例討論「情理類推」在〈喪服〉詮釋與運用中的情況，顯示此法在喪服學發展中的重要地位。最後討論歷代學者運用「情理類推」產生的詮釋失誤。

In traditional interpretations of ritual, analogy plays a significant role. Analogical thinking is used in several important approaches to explaining, and making use of, the ritual classics, such as yili shili 以例釋禮, tuizhi 推致 and yue 約. This article introduces the concept of emotional and interpersonal analogy, which is a method of interpreting the ritual classics. The discussion found here focuses on the “Sangfu” 喪服 section of the Yili 儀禮 and related texts. The article begins by delimiting the meaning of “emotional and interpersonal analogy” and by exploring its origins in ritual. The article continues with an examination of emotional and interpersonal analogy in three different aspects: the content of the classics, the practical use of the classics, and research on the classics. These three aspects together demonstrate the importance of emotional and interpersonal analogy in the development of interpretations of the “Sangfu.” Finally, the article analyzes the mistakes scholars have made by misusing emotional and interpersonal analogy.
