Rhetoric is the art of using language to communicate effectively. It involves three audience appeals: logos, pathos, and ethos, as well as the five canons of rhetoric: invention or discovery, arrangement, style, memory, and delivery. Along with grammar and logic or dialectic, rhetoric is one of the three ancient arts of discourse. From ancient Greece to the late 19th Century, it was a central part of Western education, filling the need to train public speakers and writers to move audiences to action with arguments.[1] The very act of defining has itself been a central part of rhetoric, appearing among Aristotle's Topics.[2] The word is derived from the Greek ῥητορικός (rhētorikós), "oratorical",[3] from ῥήτωρ (rhḗtōr), "public speaker",[4] related to ῥημα (rhêma), "that which is said or spoken, word, saying",[5] and ultimately derived from the verb ἐρῶ (erô), "to speak, say".[6] In its broadest sense, rhetoric concerns human discourse.[7][8]
Contemporary studies of rhetoric address a more diverse range of domains than was the case in ancient times. While classical rhetoric trained speakers to be effective persuaders in public forums and institutions like courtrooms and assemblies, contemporary rhetoric investigates human discourse writ large. Rhetoricians have studied the discourses of a wide variety of domains, including the natural and social sciences, fine art, religion, journalism, fiction, history, cartography, and architecture, along with the more traditional domains of politics and the law.[9] Public relations, lobbying, law, marketing, professional and technical writing, and advertising are modern professions that employ rhetorical practitioners.
Throughout European history, rhetoric has concerned itself with persuasion in public and political settings such as assemblies and courts. Because of its associations with democratic institutions, rhetoric is commonly said to flourish in open and democratic societies with rights of free speech, free assembly, and political enfranchisement for some portion of the population.[10]
As a course of study, rhetoric trains students to speak and/or write effectively. The rhetorical curriculum is nearly as old as the rhetorical tradition itself. Over its many centuries, the curriculum has been transformed in a number of ways, but, in general, it has emphasized the study of principles and rules of composition as a means for moving audiences. In Greece, rhetoric originated in a school of pre-Socratic philosophers known as Sophists circa 600 BC. It was later taught in the Roman Empire and during the Middle Ages as one of the three original liberal arts or trivium (along with logic and grammar).[11]
From the late 19th century, rhetoric, particularly the oral skills, has been a much lesser part of education, a trend opposed by proponents of "oracy". In the 20th century the field of communication theory has been a primary rubric under which rhetoric is studied at the tertiary education level.
The relationship between rhetoric and knowledge is one of its oldest and most interesting problems. The contemporary stereotype of rhetoric as "empty speech" or "empty words" reflects a radical division of rhetoric from knowledge, a division that has had influential adherents within the rhetorical tradition, most notably Plato in ancient Athens, and Peter Ramus in 16C Renaissance Europe.[12] It is a division that has been strongly associated with Enlightenment thinking about language.
Researchers in the rhetoric of science, however, have shown how the two are difficult to separate, and how discourse helps to create knowledge.[13] This perspective is often called "epistemic rhetoric," where communication among interlocutors is fundamental to the creation of knowledge in communities.
Emphasizing this close relationship between discourse and knowledge, contemporary rhetoricians have been associated with a number of philosophical and social scientific theories that see language and discourse as central to, rather than in conflict with, knowledge-making (See Critical Theory, Post-structuralism, Hermeneutics, Dramatism, Reflexivity).
The earliest mention of oratorical skill occurs in Homer's Iliad, where heroes like Achilles, Hektor, and Odysseus were honored for their ability to advise and exhort their peers and followers (the Laos or army) in wise and appropriate action. With the rise of the democratic polis, speaking skill was adapted to the needs of the public and political life of cities in Ancient Greece, much of which revolved around the use of oratory as the medium through which political and judicial decisions were made, and through which philosophical ideas were developed and disseminated. For modern students today, it can be difficult to remember that the wide use and availability of written texts is a phenomenon that was just coming into vogue in Classical Greece. In Classical times, many of the great thinkers and political leaders performed their works before an audience, usually in the context of a competition or contest for fame, political influence, and cultural capital; in fact, many of them are known only through the texts that their students, followers, or detractors wrote down. As has already been noted, rhetor was the Greek term for orator: A rhetor was a citizen who regularly addressed juries and political assemblies and who was thus understood to have gained some knowledge about public speaking in the process, though in general facility with language was often referred to as logôn techne, "skill with arguments" or "verbal artistry." [14]
Rhetoric thus evolved as an important art, one that provided the orator with the forms, means, and strategies for persuading an audience of the correctness of the orator's arguments. Today the term rhetoric can be used at times to refer only to the form of argumentation, often with the pejorative connotation that rhetoric is a means of obscuring the truth. Classical philosophers believed quite the contrary: the skilled use of rhetoric was essential to the discovery of truths, because it provided the means of ordering and clarifying arguments.
Organized thought about public speaking began in Ancient Greece.[15] Possibly, the first study about the power of language may be attributed to the philosopher Empedocles (d. ca. 444 BC), whose theories on human knowledge would provide a basis for many future rhetoricians. The first written manual is attributed to Corax and his pupil Tisias. Their work, as well as that of many of the early rhetoricians, grew out of the courts of law; Tisias, for example, is believed to have written judicial speeches that others delivered in the courts. Teaching in oratory was popularized in the 5th century BC by itinerant teachers known as sophists, the best known of whom were Protagoras (c.481-420 BC), Gorgias (c.483-376 BC), and Isocrates (436-338 BC). The Sophists were a disparate group who travelled from city to city, teaching in public places to attract students and offer them an education. Their central focus was on logos or what we might broadly refer to as discourse, its functions and powers. They defined parts of speech, analyzed poetry, parsed close synonyms, invented argumentation strategies, and debated the nature of reality. They claimed to make their students "better," or, in other words, to teach virtue. They thus claimed that human "excellence" was not an accident of fate or a prerogative of noble birth, but an art or "techne" that could be taught and learned. They were thus among the first humanists. Several sophists also questioned received wisdom about the gods and the Greek culture, which they believed was taken for granted by Greeks of their time, making them among the first agnostics. For example, they argued that cultural practices were a function of convention or nomos rather than blood or birth or phusis. They argued even further that morality or immorality of any action could not be judged outside of the cultural context within which it occurred. The well-known phrase, "Man is the measure of all things" arises from this belief. One of their most famous, and infamous, doctrines has to do with probability and counter arguments. They taught that every argument could be countered with an opposing argument, that an argument's effectiveness derived from how "likely" it appeared to the audience (its probability of seeming true), and that any probability argument could be countered with an inverted probability argument. Thus, if it seemed likely that a strong, poor man were guilty of robbing a rich, weak man, the strong poor man could argue, on the contrary, that this very likelihood (that he would be a suspect) makes it unlikely that he committed the crime, since he would most likely be apprehended for the crime. They also taught and were known for their ability to make the weaker (or worse) argument the stronger (or better). Aristophanes famously parodies the clever inversions that sophists were known for in his play The Clouds.
The word "sophistry" developed strong negative connotations in ancient Greece that continue today, but in ancient Greece sophists were nevertheless popular and well-paid professionals, widely respected for their abilities but also widely criticized for their excesses.
Isocrates (436-338 BC), like the sophists, taught public speaking as a means of human improvement, but he worked to distinguish himself from the Sophists, whom he saw as claiming far more than they could deliver. He suggested that while an art of virtue or excellence did exist, it was only one piece, and the least, in a process of self-improvement that relied much more heavily on native talent and desire, constant practice, and the imitation of good models. Isocrates believed that practice in speaking publicly about noble themes and important questions would function to improve the character of both speaker and audience while also offering the best service to a state.[16] He thus wrote his speeches as "models" for his students to imitate in the same way that poets might imitate Homer or Hesiod. His was the first permanent school in Athens and it is likely that Plato's Academy and Aristotle's Lyceum were founded in part as a response to Isocrates. Though he left no handbooks, his speeches ("Antidosis" and "Against the Sophists" are most relevant to students of rhetoric) became models of oratory (he was one of the canonical "Ten Attic Orators") and he had a marked influence on Cicero and Quintilian, and through them, on the entire educational system of the west.
