The Communication Tradition
What Do YOU Think?
- How many times and in how many ways have you communicated today? How would your life be different if you werenât able to communicate for an entire day?
- Think of a public figure you admire. Which of his or her characteristics attract you? How are these characteristics communicated?
- Who is the best communicator you know personally? What does that person do that makes him or her such a good communicator? Does his or her success lie in the originality of what is said, how ideas are arranged, language style, delivery, or some other factor?
- When you want to persuade others to agree with you, what kinds of appeals do you use? How often do you use rational argument? How often do you stress your own credibility or character? How often do you use emotional appeals? What kind of persuasive strategies work best for you?
- If you could change one thing about the way politicians communicate, what would it be?
- In what ways do you think modern communication technologies affect communication norms? In an age when a lot of communication occurs on social media platforms, what qualities do you think make someone a successful communicator?
- Think of three professions that donât call for skill in communication. How hard was it to think of three? (And are you sure that the three you thought of donât require communication, either with colleagues or the public?)

- What would you most like to learn about in this course?

Chapter 1 The Communication Tradition
A Brief History of Communication Study

Cave paintings attest to the universal human need to record and communicate experience. Written records in all ancient civilizations (Egypt, Babylon, India, China) show that communication has long been an object of study. |
Classical Period (500 B.C.E.-400) |
With the rise of Greek democracy, public communication became an important tool for problem solving. Rhetoric, the study of âthe available means of persuasion,â was a respected discipline taught by the great philosophers. The first known communication model, the canons of rhetoric, divided rhetoric into five parts: invention, arrangement, style, memory, and delivery. Classical rhetoric emphasized credibility, ways to ground arguments, and audience analysis. Major figures included Plato, Socrates, Aristotle, Cicero, and Quintilian. |
Medieval Period and the Renaissance (400-1600) |
In response to the rise of monolithic Christianity, rhetoric became secondary to theology. Major rhetorical acts were letter writing and preaching. Parts of the classical paradigm were kept alive, but the focus was prescriptive, not theoretical. Rhetoricians emphasized methods of embellishing and amplifying rhetorical style. Major figures included Augustine, Cassiodorus, John of Salisbury, and Erasmus. |
Modern Period (1600-1900) |
Once again, public rhetoric was a major force in determining public policy. The written word became an important medium as books and newspapers became more available. Rhetoric followed four paths: classical rhetoric revived the work of the ancients; psychological/ epistemological rhetoric investigated receiversâ psychological responses to persuasive messages; belletristic rhetoric saw written and spoken communication as art and developed theories of rhetorical criticism; elocutionists focused on developing elaborate rules for delivery. Major figures were Francis Bacon, RenĂ© Descartes, John Locke, FĂ©nelon, Lord Kames, George Campbell, Joseph Priestley, and Thomas De Quincey. |
Contemporary Period (1900-present) |
Modern departments of communication were formed. Communication study took two paths: rhetoricians used humanistic methods to analyze rhetorical effects of public discourse; communication theorists used scientific methods to analyze communication behavior as a social science. Communication study expanded to include interpersonal and group, as well as public, communication. The rise of electronic media signaled additional changes in communication study. |
