從詮釋學向度而言，欲理解黑格爾辯證法，應先從其生成史中該思想之種子及其開展乃至轉折開始。本文從黑格爾辦證性哲思之緣起，亦即法蘭克福時期之啟始，發現無限性生命存有與有限性反思之張力關係底萬有在神論及其動態之為愛之辯證。接著進入著名的耶拿時期：首先在耶拿前期其哲思呈現出獨一實體與人性主體關係之絕對形上學與其否性辯證法，然後在耶拿中期出現重大的轉折，亦即從實體轉向精神之體系性哲思典範轉移，本文主要探討該從實體典範至精神典範轉向之關鍵，亦即其從蘭克福時期至耶拿時期之前中期轉向精神辯證法生成之前史。

From the perspective of hermeneutics-dimension, to understand Hegel’s dialectics, we should begin with the embryo of the prehistory of his thinking and then its development and even turning in its generative history. This article starts from the origin of Hegel’s dialectical philosophizing, i.e., the beginning of the Frankfurt period, to discover the relationship between the infinite life-Being and finite reflection in the panentheism and its dynamics as dialectics of love. Then it will treat the famous Jena period: First, in the early stage of Jena, his philosophizing showed the absolute metaphysics as the relationship between the monistic substance and the human subject and its negative dialectics. Hereafter there was a crutial turn in the middle Jena period, that is, a paradigm shift from the substance metaphysics to the systemic philosophizing of spirit. This article mainly explores and presents the key to this shift, i.e., its history from the Frankfurt period to the early middle Jena period as prehistory of the transforming to the dialectics of spirit.
