This paper explores the concept of an infrastructure of human understanding and a new approach to communication research using a logic of positions. Communication is not, as is sometimes supposed, an instrument for conveying information from one point to another nor are the forms, languages, or capacity for understanding uniformly distributed throughout society. The infrastructure of understanding is an extraordinarily complex phenomenon which cannot be explored with traditional methods. Before taking investigations further in this new area it is necessary to redefine the nature of knowledge.
