俞琰的丹道易學思想研究

Research on Yu Yen's Ideology on 'the Book of Changes'

往昔道教學者對俞琰《易》學研究，主要侷限在「義理易學」與「象數易學」兩部分（義理為主，象數為次）。究其原因，應該是受傳統儒家《易》學學術正統思想的影響。相較之下，對於「丹道易學」（結合《易》學與內丹學，又稱道教易學）部分的關注與研究成果是較少的！因此，本論文將以俞琰兩本代表「丹道易學」的著作：《周易參同契發揮》（包括《周易參同契釋疑》）與《易外別傳》，來論述其「丹道易學」思想。

The purpose of this thesis is originated from the fact that traditional research on Yu Yen's ideology of the Book of Changes has been confined to two parts, 'Doctrine of Changes' and 'Phenomenon Science of Changes', while the former comprises the most part. The reason may be due to the effect of classic Confucianism towards the science of the Book of Changes, which results in comparatively less attention and results to and of 'Changes in Taoism of Dan.' (a combination of Changes and Nei Dan, also refer to Taoism in Changes) This paper; therefore, will discuss Yu Yen's 'Changes in Taoism of Dan' through his representative writing, Elaboration on Zhouyi can tong qi (Elaboration on the Agreement of the Three in Accordance with the Book of Changes), including The Exegesis of Zhouyi cantong qi (The Exegesis of the Agreement of the Three in Accordance with the Book of Changes) and The Anecdotal Biography of the Changes.
