写时毫无察觉，之后回过头，才见自己走过的路。本来艺术史中，也是最喜欢野兽派和表现主义那一部分。这或许是性格的倾向，《七夜》中亦是天然的流露。
以下摘自维基百科：
“尼采在《悲剧的诞生》中将艺术分为两类，阿波罗式的艺术是理智、秩序、规则和文雅的艺术；狄俄尼索斯式的艺术是恶毒、混乱和疯狂的艺术。阿波罗式的艺术代表著理智的理想，而狄俄尼索斯式的艺术则来自於人的潜意识。这两种艺术形式与代表它们的神一样：两者都是神的儿子，互不相容，又无法区分。尼采认为任何艺术作品都包含这两种形式。表现主义的基本特徵是狄俄尼索斯式的：鲜艳的颜色、扭曲的形式、绘画技巧上漫不经心、平面、缺乏透视、基於感觉，而不基於理智。
广义地说表现主义是指任何表现内心感情的艺术。当然所有的艺术品都表现艺术家的感情，但是有些作品尤其强调和表达艺术家的内心感情。
In The Birth of Tragedy Nietzsche presented his theory of the ancient dualism between two types of aesthetic experience, namely the Apollonian and the Dionysian; a dualism between the plastic "art of sculpture", of lyrical dream-inspiration, identity (the principium individuationis), order, regularity, and calm repose, and, on the other hand, the non-plastic "art of music", of intoxication, forgetfulness, chaos, and the ecstatic dissolution of identity in the collective. The analogy with the world of the Greek gods typifies the relationship between these extremes: two godsons, incompatible and yet inseparable. According to Nietzsche, both elements are present in any work of art. The basic characteristics of expressionism are Dionysian: bold colors, distorted forms-in-dissolution, two-dimensional, without perspective.
More generally the term refers to art that expresses intense emotion.”
