In Chiang Hsun's words: "Laozi deeply probes both sensory perception and states of mind." By way of example, Chiang cites the "white space" deliberately left in Chinese traditional landscape paintings: art is a sensory activity, but unmoderated sensual indulgence numbs the senses.
「老子對感官與心境做了深入探討」，蔣勳以山水畫中的「留白」為例，藝術是通過感官的活動，未經節制的感官泛濫，結果是感官的麻痺。
