What is communication? The question is deceptively simple, not because there is no straightforward answer but because there are so many answers, many of which may seem perfectly straightforward in themselves. Communication is human interaction . . . the transfer of information . . . effect or influence . . . mutual understanding . . . community . . . culture . . . and so on. Any effort to reconcile these straightforward definitions quickly runs into contradictions and puzzles. Human interaction involves the transfer of information, but machines also exchange information, and so do animals, so do chemical molecules. Is human communication essentially different in some way? Effect or influence is not the same as mutual understanding and is sometimes quite the opposite. Is mutual understanding ever really possible? Is communication an intentional act or a process that goes on regardless of our intentions? If communication is culture, is it necessarily also community? Doesn’t the concept of communication vary, depending on how it is understood and practiced in each particular culture? Is it all relative, then, or are there good reasons to be critical of particular cultural concepts? Obviously, communication can be defined in many different ways, and at least some of those differences seem potentially consequential. Whether we think of communication as essentially information transfer, or mutual understanding, or culture can make a difference, not only for how we understand the process intellectually but also for how we communicate in practice. Of course, we needn’t all agree on a single definition or choose a single definition for ourselves, but we can learn a lot by contemplating and debating the theoretical and practical implications of different concepts and theories of communication. This is what communication theorists do, and the academic subject of communication theory is a rich and varied resource for learning how to think about communication. The field of communication theory encompasses a number of distinct intellectual traditions, some thousands of years old, others very new. Some theories lend themselves to scientific empirical studies of communication, others to philosophical reflection or cultural criticism. This article is intended to represent the diversity of communication theory, hopefully in ways that are useful and inviting of further study rather than merely confusing. Included are introductory overview essays, textbooks, and other general sources such as encyclopedias, anthologies, and journals. Other sections cover historical studies on the idea of communication, ethnographic studies on culturally based concepts of communication, and theoretical models of the communication process. The heading entitled Conceptual Issues is divided into eleven subsections, each focusing on a key conceptual issue or controversy in communication theory.
