罗伯特·洛根，加拿大物理学家和媒介环境学家，与麦克卢汉合作著书立说，从物理学转向传播学和媒介理论；在捍卫、继承和发扬麦克卢汉媒介理论的过程中完成了自己的理论创新。在跨越诸多文科的过程中形成了人脑、语言、心灵、信息和文化的大一 统理论，提出“心灵=大脑+语言+文化”的心灵延伸模型，即人的认知模型；在综合诸多文理学科的过程中提出符号理论和泛信息论，成为著名的跨学科理论家。

Robert Logan, a Canadian physicist and media environmentalist, co-authored a book with McLuhan on the transition from physics to communication and media theory, and completed his theoretical innovation in defending, inheriting and developing McLuhan's media theory. In the process of crossing many liberal arts disciplines, a unifed theory of human brain, language, mind, information and culture has been formed, and a mental extension model of “mind = brain + language + culture” has been put forward, that is, a cognitive model of human being. In the process of synthesizing many liberal arts and sciences, he put forward symbolic theory and Paninformation theory and became a famous interdisciplinary theorist.
