本文从存在现象学、技术现象学、后人类理论出发，结合移动网络、虚拟现实、人 工智能等新媒体实践，回顾并探讨了身体议题在传播学研究中的基本状况，以及对传播 学创新发展的价值与意义。本文聚焦交流者的身体，在描述传播主体从意识主体、身 体-主体、智能主体的演变过程中，呈现并阐释了传播与多种身体形式、多重在场方式 的复杂关系。据此认为，所谓在场或缺席，即是主体现身或脱离于现实与虚拟杂糅的关 系网络，传播就是编织关系网络的身体实践，物理的、信息的、意义的多重网络通过传 播聚焦于智能身体这个节点主体。传播研究必得回归身体世界，将自身重新放置到当前 智能主体的世界中，才能重建传播与人类存在的根本性关联。

Starting from existential phenomenology, phenomenology of technology and theory of post-humanism, the essay traces and investigates the basic condition of the topic of “body” in communication studies as well as its value and meaning in the innovation of communication studies with the analysis of new media practices like mobile networks, vitural reality and antifcial intelligence. Focusing on the bodies of communicators, the author displays and elaborates the complex relationship between communication and multiple forms of bodies and multiple forms of presence by describing the evolution of communicating body from consciousness subject, body-subject to intelligent subject. It is pointed out that the so-called presence or absence is actually the fact that the subject is in or out of the combined relation networks made up of reality and virtuality. Communication should be seem as body practices weaving the relation networks and multiple networks of physical world, information and signifcance converge on the intelligent bodies as subjects of nodes. Communication studies must turn back to the world of bodies and reposit itself into the contemporary world of intelligent subjects to reestablish the fundamental relationship between communication and the human presence.
