干宝对京房八宫易学的重建

Gan Bao's Reconstruction of Jing Fang's Eight Palaces-Oriented Tradition of the Changes

东晋易学家干宝在王弼玄学化义理易学兴起后,粹集汉易诸家象数体例,整合京房八宫纳甲与夏侯胜尚书学、翼奉诗经学中的阴阳五行思想,重建了京房八宫易学,借以诠释《周易》一经,延续了汉代易学与汉代经学一脉。干宝接纳京房八宫易学,以汉代易学的视域,夯实了它的卦气阴阳消息的基本语境,进而针对京房八宫六十四卦的世次、世爻之阴阳及各卦六爻所纳之辰与辰所对应的五行,从阴阳消息下五行的流转出发,开显了造化性情场与生命性情,令八宫易学得到全方位重建,为易学术向道的转化提供了范例。

After the rise of Wang Bi's(226-249)Yi scholarship of meanings and principles with the feature of metaphysics,Gan Bao(d.336),a scholar of the Eastern Jin Dynasty(317-420),compiled the image-numerological interpretations of the Yijing popular in the Han dynasty(206 BCE-220 CE)and integrated Jing Fang's(37-77 BCE)tradition attaching the heavenly stems and earthly branches to the sixty-four hexagrams permutated in eight palaces,Xia Housheng's(fl.70 BCE)study of the Classic of History,and the theory of yin-yang and five elements in Yi Feng's(fl.40 BCE)study of the Classic of Poetry,by which he reconstructed Jing Fang's tradition of the Eight Palaces to interpret the Yijing and succeed the lineage of Changes scholarship and Confucian classics studies formed in the Han dynasty.Gan Bao accepted Jing Fang's theory based on the Eight Palaces and,from the perspective of the Yi scholarship in the Han dynasty,solidified its basic theoretical context of guaqi(correlating trigrams and hexagrams with the seasonal points),the waxing and waning of yin and yang.Then he focused on the order of the 64 hexagrams in Jing Fang's eight palaces,yin and yang of the generation line世爻shi yao,the earthly branches corresponding to the six lines and their attributes of five agents.Starting from the circulation of the five elements under the waxing and waning of yin and yang,he revealed the circumstances of creation and life,and reconstructed the theory of the Eight Palaces in all aspects,providing a paradigm for the transformation of the Changes from divinatory method to the Dao.
