Communicology is Vilem Flusser's first thesis on his concepts of technical images and technical imagination. In this foundational text he lays the groundwork for later work, offering a philosophical approach to communication as a phenomenon that permeates every aspect of human existence. Clearly organized around questions such as "What is Communication?," "What are Codes?," and "What is Technical Imagination?," the work touches on theater, photography, film, television, and more. Originally written in 1978, but only posthumously published in German, the book is one of the clearest statements of Flusser's theory of communication as involving a variably mediated relation between humans and the world. Although Flusser was writing in the 1970s, his work demonstrates a prescience that makes it of significant contemporary interest to scholars in visual culture, art history, media studies, and philosophy.
