作為哲學思想的集大成之作，《呂氏春秋》廣泛且精要地體現秦漢之際的核心思潮，其中應感論更是《呂氏春秋》重要的思想要素，並進一步延伸、影響了漢代哲學的形塑。本文主要即在探討，《呂氏春秋》應感論論及的相互感知與回應有何重要性？其所蘊含的倫理意義為何？本文將指出，應感論的特質及重要性一方面在於嘗試以之彌補語言、符號溝通的不足及缺陷，並試圖跨越人我互動的空間限制；另方面則涉及統治成效的根本說明。至於其中含蘊的倫理意涵，則主要包括幾方面：一是凸顯精誠、專一的內在德性，以此作為倫理互動的內在依據。二是倫理關係的場域不限於人的範圍，而已擴及人與萬物的互動。其三、倫理關係不限於在場的面對面，其在強調超越語言的互動可能時，也同時強調跨越空間限制的人、我或人、物關係。

As the comprehensive writing of the pre-Qin philosophy, The Annals of Lu Buwei shows the deep philosophical meaning during the time of Qin-Han dynasty. Among the thought of this book, the idea about ＂perceiving and response＂ especially shows the main feature of its philosophical thought and affects the form of the metaphysical thought in Han dynasty. This essay focuses on exploring the features and the importance of the thought about ＂perceiving and response＂ in The Annals of Lu Buwei. And what's the ethical implication in this book. We will point out that the role and the features of the theory of ＂perceiving and response＂ are on the one hand as the supplement to the shortage and limitation of language, and as a way to overcome the limitation of the interaction for the space on the other hand. About the ethical implication of this book, we will point out that there are at least three dimensions. First, it highlights the value of the virtues of genuineness, purity, sincereness and concentration, and always regards them as the ground and conditions of good ethical relationship in the book. Second, the ethical field does not limit to human beings, but expends to all the things in the world no matter they're living beings or not. Third, the ethical relationship no more limits to face to face, here and now. It transcends the limitation of space, distance as well as the limitation of language in people's interaction.
