從尹灣漢墓簡牘看中國社會的擇日傳統

A Study of the Tradition of Selection of Auspicious Time and Space in Chinese Society through the Strips Excavated at Yinwan Han Tomb

選擇術或為中國社會所流傳各類術數當中內容最龐雜者，此術透過時空的制約曾影響及歷代億萬中國人的日常生活，但先前卻很少獲得學術界足夠的關注。本文即先理清尹灣漢墓簡牘中涉及選擇術的內容，以掌握該術早期的型態，並透過個案研究與後世的選擇術規則相比較，藉以析探中國術數的發展模式及其與社會之間的互動關係，並嘗試探討選擇術何以能在華人社會存留兩千餘年而不被時代所淘汰。透過類似的研究，不僅可以增進我們對術數史的了解，更有機會具體豐富我們對古代通俗文化和古人生活禮俗的認識。

Xuanze shu (method to select auspicious time and space) may be the most complicated branch and occupy the most abundant part of Chinese pseudo-science. Through the constraint of space and time, it affected the daily life of billions of Chinese during the last two thousand years; however, it has attracted little attention from scholars. This article tries to clarify the content of strips related to xuanze shu excavated at Yin wan Han tomb in order to gain a better understanding of the early form of this method. The author also investigates through detailed case studies the evolution pattern of xuanze shu through history and its interaction with society. The reason why xuanze shu has survived the dramatic changes of the modem society is analyzed. This paper provides an excellent example of how studies of pseudo-science can also enrich our knowledge of the popular culture and daily life of ancient Chinese.
