人们对客观世界的认识,离不开眼、耳、口、鼻等感觉器官。正如苏轼所言“惟江上之清风,与山间之明月,耳得之而为声,目遇之而成色。”又老子言“五色使人之目盲,五味使人之口爽,五音使人之耳聋。”都说的是人们的感官对外界的认知或外界对人们的影响。那当我们“观古今于须臾”“抚四海于一方”,“情动于中而辞发”时就必然会对外在世界的声、光、色、形、态、味有所感悟, People’s understanding of the objective world cannot be separated from the sense organs of the eyes, ears, mouth and nose. As Su Shi said, “Only the breeze on the river, and the bright moon between the mountains, and the sound of the ear, the result of the encounter.” And Laozi remarked, “The five colors make people blind, and the five flavors make people happy. People are deaf.” What people say is the perception of the outside world by people’s senses or the influence of the outside world on people. When we “viewed ancient times and modern times” and “always care about the ancient world,” “promoting the whole world on the one hand,” and “being affectionate in China and resigning,” we are bound to feel sentiment about the sound, light, color, shape, state, and taste of the outside world.
