「章法」所凸顯的，是篇章內容的邏輯結構。由於這種邏輯結構，乃對應於自然，由「陰陽二元」為基礎，經橫向之「移位」、「轉位」與縱向之「包孕」過程，使陰陽產生多種變化，形成細緻、複雜、多層的結構系統。單以「包孕」而言，就涉及「陽／『陰、陽』」與「陰／『陰、陽』」兩類的陰陽變化，比「移位」與「轉位」更趨複雜。本文即著眼於此，探求章法包孕結構之陰陽變化類型，以見它在章法結構系統中的重要性。

The organization of writing is the way to present the logical structure of subject matters in literary works. Such a structure corresponds to the dualism between masculine (Yang) and feminine (Yin) attributes of the universe. By means of horizontal ＂shift＂ and ＂transfer＂ as well as vertical ＂conceiveness＂, variation occurs in Yin and Yang that contributes to a delicate, complicated, and multi-layer structure. In point of the conceiving structure, there are two kinds of variations that involve ＂Yang/Yin-Yang＂ and ＂Yang/Yin-Yang＂. In consideration of such a complicated variation, this article explores the categories of Yin-Yang variation in the conceiving structure and discusses its significance in the structural system of the organization of writing.
