Scholars have debated the scope of rhetoric since ancient times. Although some have limited rhetoric to the specific realm of political discourse, many modern scholars liberate it to encompass every aspect of culture. 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 such as 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, digital media, fiction, history, cartography, and architecture, along with the more traditional domains of politics and the law.[9] Many contemporary approaches treat rhetoric as human communication that includes purposeful and strategic manipulation of symbols. Public relations, lobbying, law, marketing, professional and technical writing, and advertising are modern professions that employ rhetorical practitioners.
Because the ancient Greeks highly valued public political participation, rhetoric emerged as a crucial tool to influence politics. Consequently, rhetoric remains associated with its political origins. However, even the original instructors of Western speech—the Sophists—disputed this limited view of rhetoric. According to the Sophists, such as Gorgias, a successful rhetorician could speak convincingly on any topic, regardless of his experience in that field. This method suggested rhetoric could be a means of communicating any expertise, not just politics. In his Encomium to Helen, Gorgias even applied rhetoric to fiction by seeking for his own pleasure to prove the blamelessness of the mythical Helen of Troy in starting the Trojan War.[10]
Looking to another key rhetorical theorist, Plato defined the scope of rhetoric according to his negative opinions of the art. He criticized the Sophists for using rhetoric as a means of deceit instead of discovering truth. In "Gorgias," one of his Socratic Dialogues, Plato defines rhetoric as the persuasion of ignorant masses within the courts and assemblies.[11] Rhetoric, in Plato's opinion, is merely a form of flattery and functions similarly to cookery, which masks the undesirability of unhealthy food by making it taste good. Thus, Plato considered any speech of lengthy prose aimed at flattery as within the scope of rhetoric.
Aristotle both redeemed rhetoric from his teacher and narrowed its focus by defining three genres of rhetoric—deliberative, forensic or judicial, and epideictic.[12] Yet, even as he provided order to existing rhetorical theories, Aristotle extended the definition of rhetoric, calling it the ability to identify the appropriate means of persuasion in a given situation, thereby making rhetoric applicable to all fields, not just politics. When one considers that rhetoric included torture (in the sense that the practice of torture is a form of persuasion or coercion), it is clear that rhetoric cannot be viewed only in academic terms. However, the enthymeme based upon logic (especially, based upon the syllogism) was viewed as the basis of rhetoric.
However, since the time of Aristotle, logic has changed. For example, Modal logic has undergone a major development that also modifies rhetoric.[13] Yet, Aristotle also outlined generic constraints that focused the rhetorical art squarely within the domain of public political practice. He restricted rhetoric to the domain of the contingent or probable: those matters that admit multiple legitimate opinions or arguments.
The contemporary neo-Aristotelian and neo-Sophistic positions on rhetoric mirror the division between the Sophists and Aristotle. Neo-Aristotelians generally study rhetoric as political discourse, while the neo-Sophistic view contends that rhetoric cannot be so limited. Rhetorical scholar Michael Leff characterizes the conflict between these positions as viewing rhetoric as a "thing contained" versus a "container." The neo-Aristotelian view threatens the study of rhetoric by restraining it to such a limited field, ignoring many critical applications of rhetorical theory, criticism, and practice. Simultaneously, the neo-Sophists threaten to expand rhetoric beyond a point of coherent theoretical value.
Over the past century, people studying rhetoric have tended to enlarge its object domain beyond speech texts. Kenneth Burke asserted humans use rhetoric to resolve conflicts by identifying shared characteristics and interests in symbols. By nature, humans engage in identification, either to identify themselves or another individual with a group. This definition of rhetoric as identification broadened the scope from strategic and overt political persuasion to the more implicit tactics of identification found in an immense range of sources.[14]
Among the many scholars who have since pursued Burke's line of thought, James Boyd White sees rhetoric as a broader domain of social experience in his notion of constitutive rhetoric. Influenced by theories of social construction, White argues that culture is "reconstituted" through language. Just as language influences people, people influence language. Language is socially constructed, and depends on the meanings people attach to it. Because language is not rigid and changes depending on the situation, the very usage of language is rhetorical. An author, White would say, is always trying to construct a new world and persuading his or her readers to share that world within the text.[15]
Individuals engage in the rhetorical process anytime they speak or produce meaning. Even in the field of science, the practices of which were once viewed as being merely the objective testing and reporting of knowledge, scientists must persuade their audience to accept their findings by sufficiently demonstrating that their study or experiment was conducted reliably and resulted in sufficient evidence to support their conclusions.
The vast scope of rhetoric is difficult to define; however, political discourse remains, in many ways, the paradigmatic example for studying and theorizing specific techniques and conceptions of persuasion, considered by many a synonym for "rhetoric."[16]
Rhetoric as a civic art
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. Those who classify rhetoric as a civic art believe that rhetoric has the power to shape communities, form the character of citizens and greatly impact civic life.
Rhetoric was viewed as a civic art by several of the ancient philosophers. Aristotle and Isocrates were two of the first to see rhetoric in this light. In his work, Antidosis, Isocrates states, "We have come together and founded cities and made laws and invented arts; and, generally speaking, there is no institution devised by man which the power of speech has not helped us to establish." With this statement he argues that rhetoric is a fundamental part of civic life in every society and that it has been necessary in the foundation of all aspects of society. He further argues in his piece Against the Sophists that rhetoric, although it cannot be taught to just anyone, is capable of shaping the character of man. He writes, "I do think that the study of political discourse can help more than any other thing to stimulate and form such qualities of character." Aristotle, writing several years after Isocrates, supported many of his arguments and continued to make arguments for rhetoric as a civic art.
In the words of Aristotle, in his essay Rhetoric, rhetoric is "... the faculty of observing in any given case the available means of persuasion." According to Aristotle, this art of persuasion could be used in public settings in three different ways. He writes in Book I, Chapter III, "A member of the assembly decides about future events, a juryman about past events: while those who merely decide on the orator's skill are observers. From this it follows that there are three divisions of oratory- (1) political, (2) forensic, and (3) the ceremonial oratory of display". Eugene Garver, in his critique of "Aristotle's Rhetoric", confirms that Aristotle viewed rhetoric as a civic art. Garver writes, "Rhetoric articulates a civic art of rhetoric, combining the almost incompatible properties of techne and appropriateness to citizens."[17] Each of Aristotle's divisions plays a role in civic life and can be used in a different way to impact cities.
Because rhetoric is a public art capable of shaping opinion, some of the ancients including Plato found fault in it. They claimed that while it could be used to improve civic life, it could be used equally easily to deceive or manipulate with negative effects on the city. The masses were incapable of analyzing or deciding anything on their own and would therefore be swayed by the most persuasive speeches. Thus, civic life could be controlled by the one who could deliver the best speech. Plato's explores the problematic moral status of rhetoric twice: in Gorgias, a dialogue named for the famed Sophist, and in The Phaedrus, a dialogue best known for its commentary on love.
More trusting in the power of rhetoric to support a republic, the Roman orator Cicero argued that art required something more than eloquence. A good orator needed also to be a good man, a person enlightened on a variety of civic topics. He describes the proper training of the orator in his major text on rhetoric, De Oratore, modeled on Plato's dialogues.
Modern day works continue to support the claims of the ancients that rhetoric is an art capable of influencing civic life. In his work Political Style, Robert Hariman claims, "Furthermore, questions of freedom, equality, and justice often are raised and addressed through performances ranging from debates to demonstrations without loss of moral content".[18] James Boyd White argues further that rhetoric is capable not only of addressing issues of political interest but that it can influence culture as a whole. In his book, When Words Lose Their Meaning, he argues that words of persuasion and identification define community and civic life. He states that words produce "... the methods by which culture is maintained, criticized, and transformed."[19] Both White and Hariman agree that words and rhetoric have the power to shape culture and civic life.
In modern times, rhetoric has consistently remained relevant as a civic art. In speeches, as well as in non-verbal forms, rhetoric continues to be used as a tool to influence communities from local to national levels.
Rhetoric as a course of study
Rhetoric as a course of study has evolved significantly since its ancient beginnings. Through the ages, the study and teaching of rhetoric has adapted to the particular exigencies of the time and venue.[20] The study of rhetoric has conformed to a multitude of different applications, ranging from architecture to literature.[21] Although the curriculum has transformed in a number of ways, it has generally emphasized the study of principles and rules of composition as a means for moving audiences. Generally speaking, the study of rhetoric trains students to speak and/or write effectively, as well as critically understand and analyze discourse.
Rhetoric began as a civic art in Ancient Greece where students were trained to develop tactics of oratorical persuasion, especially in legal disputes. Rhetoric originated in a school of pre-Socratic philosophers known as the Sophists circa 600 BC. Demosthenes and Lysias emerged as major orators during this period, and Isocrates and Gorgias as prominent teachers. Rhetorical education focused on five particular canons: inventio (invention), dispositio (arrangement), elocutio (style), memoria (memory), and actio (delivery). Modern teachings continue to reference these rhetorical leaders and their work in discussions of classical rhetoric and persuasion.
Rhetoric was later taught in universities during the Middle Ages as one of the three original liberal arts or trivium (along with logic and grammar).[22] During the medieval period, political rhetoric declined as republican oratory died out and the emperors of Rome garnered increasing authority. With the rise of European monarchs in following centuries, rhetoric shifted into the courtly and religious applications. Augustine exerted strong influence on Christian rhetoric in the Middle Ages, advocating the use of rhetoric to lead audiences to truth and understanding, especially in the church. The study of liberal arts, he believed, contributed to rhetorical study: "In the case of a keen and ardent nature, fine words will come more readily through reading and hearing the eloquent than by pursuing the rules of rhetoric."[23] Poetry and letter writing, for instance, became a central component of rhetorical study during the Middle Ages.[24] After the fall of the Republic in Rome, poetry became a tool for rhetorical training since there were fewer opportunities for political speech.[25] Letter writing was the primary form through which business was conducted both in state and church, so it became an important aspect of rhetorical education.[26]
Rhetorical education became more restrained as style and substance separated in 16th-century France with Peter Ramus, and attention turned to the scientific method. That is, influential scholars like Ramus argued that the processes of invention and arrangement should be elevated to the domain of philosophy, while rhetorical instruction should be chiefly concerned with the use of figures and other forms of the ornamentation of language. Scholars such as Francis Bacon developed the study of "scientific rhetoric."[27] This concentration rejected the elaborate style characteristic of the classical oration. This plain language carried over to John Locke's teaching, which emphasized concrete knowledge and steered away from ornamentation in speech, further alienating rhetorical instruction, which was identified wholly with this ornamentation, from the pursuit of knowledge.
In the 18th century, rhetoric assumed a more social role, initiating the creation of new education systems. "Elocution schools" arose (predominantly in England) in which females analyzed classic literature, most notably the works of William Shakespeare, and discussed pronunciation tactics.[28]
The study of rhetoric underwent a revival with the rise of democratic institutions during the late 18th and early 19th centuries. Scotland's author and theorist Hugh Blair served as a key leader of this movement during the late 18th century. In his most famous work "Lectures on Rhetoric and Belles Lettres", he advocates rhetorical study for common citizens as a resource for social success. Many American colleges and secondary schools used Blair's text throughout the 19th century to train students of rhetoric.[29]
Political rhetoric also underwent renewal in the wake of the US and French revolutions. The rhetorical studies of ancient Greece and Rome were resurrected in the studies of the era as speakers and teachers looked to Cicero and others to inspire defense of the new republic. Leading rhetorical theorists included John Quincy Adams of Harvard who advocated the democratic advancement of rhetorical art. Harvard's founding of the Boylston Professorship of Rhetoric and Oratory sparked the growth of rhetorical study in colleges across the United States.[26] Harvard's rhetoric program drew inspiration from literary sources to guide organization and style.
Debate clubs and lyceums also developed as forums in which common citizens could hear speakers and sharpen debate skills. The American lyceum in particular was seen as both an educational and social institution, featuring group discussions and guest lecturers.[30] These programs cultivated democratic values and promoted active participation in political analysis.
Throughout the 20th century, rhetoric developed as a concentrated field of study with the establishment of rhetorical courses in high schools and universities. Courses such as public speaking and speech analysis apply fundamental Greek theories (such as the modes of persuasion: ethos, pathos, and logos) as well as trace rhetorical development throughout the course of history. Rhetoric has earned a more esteemed reputation as a field of study with the emergence of Communication Studies departments in university programs and in conjunction with the linguistic turn. Rhetorical study has broadened in scope, and is especially utilized by the fields of marketing, politics, and literature.
Rhetoric, as an area of study, is concerned with how humans use symbols, especially language, to reach agreement that permits coordinated effort of some sort.[31] Harvard University, the first university in the United States, based on the European model, taught a basic curriculum, including rhetoric. Rhetoric, in this sense, how to properly give speeches, played an important role in their training. Rhetoric was soon taught in departments of English as well.[32]
Rhetoric and knowledge
Main article: Epistemology
The relationship between rhetoric and knowledge is characteristic for the nature of human understanding, and reflects two closely related but adversarial traditions. Rhetoric is concerned with the influence on our beliefs or behaviors with the available means, usually in order to achieve certain effects, such as consensus on some issue. Knowledge, on the other hand, is concerned with the justification of our beliefs with the available evidence or good reasons.
Hence both are concerned with beliefs, but treat them differently. While a justified true belief is an end in itself for knowledge, it is a possible means among many for rhetoric depending on its influence on people. Plato famously criticized the sophists for their attempts to influence people's beliefs without good reasons: it was rhetoric and slander which had persuaded people to sentence his friend Socrates to death. Indifference to truth or rightness may arbitrarily or randomly destroy anyone or entire societies.
Philosophers seldom ascribe rhetoric epistemic value. Yet one might argue that some writers (primarily in the tradition of Nietzsche, continental philo., postmodern "theory") appreciate rhetoric more, often with the underlying assumption that knowledge is not based on truth but on social or pragmatic agreements. In that case rhetoric might have a major influence on knowledge. Nevertheless, also agreements have properties or relations open for discovery which enables us to identify some of them as 'social' or 'pragmatic' rather than, say, 'random' or 'mechanical'. In that case knowledge is not primarily based on agreements but discovery.
Since rhetoric includes the use of argument in order to achieve justified and true conclusions, or the effect of enlightenment, then it is closely related to knowledge (see, for example, Rhetorical reason).
History
Rhetoric has its origins in Mesopotamia.[33] Some of the earliest examples of rhetoric can be found in the Akkadian writings of the princess and priestess Enheduanna (ca. 2285–2250 BC),[34] while later examples can be found in the Neo-Assyrian Empire during the time of Sennacherib (704–681 BC).[35] In ancient Egypt, rhetoric had existed since at least the Middle Kingdom period (ca. 2080–1640 BC). The Egyptians held eloquent speaking in high esteem, and it was a skill that had a very high value in their society. The "Egyptian rules of rhetoric" also clearly specified that "knowing when not to speak is essential, and very respected, rhetorical knowledge." Their "approach to rhetoric" was thus a "balance between eloquence and wise silence." Their rules of speech also strongly emphasized "adherence to social behaviors that support a conservative status quo" and they held that "skilled speech should support, not question, society."[36] In ancient China, rhetoric dates back to the Chinese philosopher, Confucius (551-479 BC), and continued with later followers. The tradition of Confucianism emphasized the use of eloquence in speaking.[37] The use of rhetoric can also be found in the ancient Biblical tradition.[38]
In ancient Greece, 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."[39]
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.
Sophists
Main article: Sophists
In Europe, organized thought about public speaking began in ancient Greece.[40] 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
Main article: Isocrates
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 city. In fact, Isocrates was an outspoken champion of rhetoric as a mode of civic engagement.[41] He thus wrote his speeches as "models" for his students to imitate in the same way that poets might imitate Homer or Hesiod, seeking to inspire in them a desire to attain fame through civic leadership. 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 keys to his entire educational program. He had a marked influence on Cicero and Quintilian, and through them, on the entire educational system of the west.
Plato
Main articles: Plato and Platonism
Plato (427-347 BC) famously outlined the differences between true and false rhetoric in a number of dialogues; particularly the Gorgias and Phaedrus dialogues wherein Plato disputes the sophistic notion that the art of persuasion (the sophists' art, which he calls "rhetoric"), can exist independent of the art of dialectic. Plato claims that since sophists appeal only to what seems probable, they are not advancing their students and audiences, but simply flattering them with what they want to hear. While Plato's condemnation of rhetoric is clear in the Gorgias, in the Phaedrus he suggests the possibility of a true art wherein rhetoric is based upon the knowledge produced by dialectic, and relies on a dialectically informed rhetoric to appeal to the main character, Phaedrus, to take up philosophy. Thus Plato's rhetoric is actually dialectic (or philosophy) "turned" toward those who are not yet philosophers and are thus unready to pursue dialectic directly. Plato's animosity against rhetoric, and against the sophists, derives not only from their inflated claims to teach virtue and their reliance on appearances, but from the fact that his teacher, Socrates, was sentenced to death after sophists' efforts.

Main article: Rhetoric (Aristotle)


A marble bust of Aristotle
Aristotle (384-322 BC) was a student of Plato who famously set forth an extended treatise on rhetoric that still repays careful study today. In the first sentence of The Art of Rhetoric, Aristotle says that "rhetoric is the counterpart [literally, the antistrophe] of dialectic." As the "antistrophe" of a Greek ode responds to and is patterned after the structure of the "strophe" (they form two sections of the whole and are sung by two parts of the chorus), so the art of rhetoric follows and is structurally patterned after the art of dialectic because both are arts of discourse production. Thus, while dialectical methods are necessary to find truth in theoretical matters, rhetorical methods are required in practical matters such as adjudicating somebody's guilt or innocence when charged in a court of law, or adjudicating a prudent course of action to be taken in a deliberative assembly. The core features dialectic include the absence of determined subject matter, its elaboration on earlier empirical practice, the explication of its aims, the type of utility and the definition of the proper function.
For Plato and Aristotle, dialectic involves persuasion, so when Aristotle says that rhetoric is the antistrophe of dialectic, he means that rhetoric as he uses the term has a domain or scope of application that is parallel to, but different from, the domain or scope of application of dialectic. In Nietzsche Humanist (1998: 129), Claude Pavur explains that "[t]he Greek prefix 'anti' does not merely designate opposition, but it can also mean 'in place of.'" When Aristotle characterizes rhetoric as the antistrophe of dialectic, he no doubt means that rhetoric is used in place of dialectic when we are discussing civic issues in a court of law or in a legislative assembly. The domain of rhetoric is civic affairs and practical decision making in civic affairs, not theoretical considerations of operational definitions of terms and clarification of thought. These, for him, are in the domain of dialectic.
Aristotle's treatise on rhetoric is an attempt to systematically describe civic rhetoric as a human art or skill (techne). It is more of an objective theory than it is an interpretive theory with a rhetorical tradition. Aristotle's "art" of rhetoric emphasizes on persuasion to be the purpose of rhetoric. His definition of rhetoric as "the faculty of observing in any given case the available means of persuasion," essentially a mode of discovery, seems to limit the art to the inventional process, and Aristotle heavily emphasizes the logical aspect of this process. In his world, rhetoric is the art of discovering all available means of persuasion. A speaker supports the probability of a message by logical, ethical, and emotional proofs. Some form of logos, ethos, and pathos is present in every possible public presentation that exists. But the treatise in fact also discusses not only elements of style and (briefly) delivery, but also emotional appeals (pathos) and characterological appeals (ethos).
Aristotle identifies three steps or "offices" of rhetoric—invention, arrangement, and style—and three different types of rhetorical proof: ethos (Aristotle's theory of character and how the character and credibility of a speaker can influence an audience to consider him/her to be believable—there being three qualities that contribute to a credible ethos: perceived intelligence, virtuous character, and goodwill);[42] pathos (the use of emotional appeals to alter the audience's judgment through metaphor, amplification, storytelling, or presenting the topic in a way that evokes strong emotions in the audience.); and, logos (the use of reasoning, either inductive or deductive, to construct an argument).
Aristotle emphasized enthymematic reasoning as central to the process of rhetorical invention, though later rhetorical theorists placed much less emphasis on it. An "enthymeme" would follow today's form of a syllogism; however it would exclude either the major or minor premise. An enthymeme is persuasive because the audience is providing the missing premise. Because the audience is able to provide the missing premise, they are more likely to be persuaded by the message.
Aristotle identified three different types or genres of civic rhetoric. Forensic (also known as judicial, was concerned with determining the truth or falseness of events that took place in the past and issues of guilt. An example of forensic rhetoric would be in a courtroom. Deliberative (also known as political), was concerned with determining whether or not particular actions should or should not be taken in the future. Making laws would be an example of deliberative rhetoric. Epideictic (also known as ceremonial), was concerned with praise and blame, values, right and wrong, demonstrating beauty and skill in the present. Examples of epideictic rhetoric would include a eulogy or a wedding toast.
Canons
The Five Canons of Rhetoric serve as a guide to creating persuasive messages and arguments. These are invention (the process of developing arguments); style (determining how to present the arguments); arrangement (organizing the arguments for extreme effect); delivery (the gestures, pronunciation, tone and pace used when presenting the persuasive arguments); and memory (the process of learning and memorizing the speech and persuasive messages.)[43]
In the rhetoric field, there is an intellectual debate about Aristotle's definition of rhetoric. Some believe that Aristotle defines rhetoric in On Rhetoric as the art of persuasion, while others think he defines it as the art of judgment. Rhetoric as the art of judgment would mean the rhetor discerns the available means of persuasion with a choice. Aristotle also says rhetoric is concerned with judgment because the audience judges the rhetor's ethos.
One of the most famous of Aristotelian doctrines was the idea of topics (also referred to as common topics or commonplaces). Though the term had a wide range of application (as a memory technique or compositional exercise, for example) it most often referred to the "seats of argument"—the list of categories of thought or modes of reasoning—that a speaker could use to generate arguments or proofs. The topics were thus a heuristic or inventional tool designed to help speakers categorize and thus better retain and apply frequently used types of argument. For example, since we often see effects as "like" their causes, one way to invent an argument (about a future effect) is by discussing the cause (which it will be "like"). This and other rhetorical topics derive from Aristotle's belief that there are certain predictable ways in which humans (particularly non-specialists) draw conclusions from premises. Based upon and adapted from his dialectical Topics, the rhetorical topics became a central feature of later rhetorical theorizing, most famously in Cicero's work of that name.
Cicero
Main articles: Cicero, De Inventione, De Oratore, Brutus (Cicero), De Optimo Genere Oratorum and De Partitionibus Oratoriae


Bust of Marcus Tullius Cicero
For the Romans, oration became an important part of public life. Cicero (106-43 BC) was chief among Roman rhetoricians and remains the best known ancient orator and the only orator who both spoke in public and produced treatises on the subject. Rhetorica ad Herennium, formerly attributed to Cicero but now considered to be of unknown authorship, is one of the most significant works on rhetoric and is still widely used as a reference today. It is an extensive reference on the use of rhetoric, and in the Middle Ages and Renaissance, it achieved wide publication as an advanced school text on rhetoric.
Cicero is considered one of the most significant rhetoricians of all time. His works include the early and very influential De Inventione (On Invention, often read alongside the Ad Herennium as the two basic texts of rhetorical theory throughout the Middle Ages and into the Renaissance), De Oratore (a fuller statement of rhetorical principles in dialogue form), Topics (a rhetorical treatment of common topics, highly influential through the Renaissance), Brutus (Cicero) (a discussion of famous orators) and Orator (a defense of Cicero's style). Cicero also left a large body of speeches and letters which would establish the outlines of Latin eloquence and style for generations to come. It was the rediscovery of Cicero's speeches (such as the defense of Archias) and letters (to Atticus) by Italians like Petrarch that, in part, ignited the cultural innovations that we know as the Renaissance. He championed the learning of Greek (and Greek rhetoric), contributed to Roman ethics, linguistics, philosophy, and politics, and emphasized the importance of all forms of appeal (emotion, humor, stylistic range, irony and digression in addition to pure reasoning) in oratory. But perhaps his most significant contribution to subsequent rhetoric, and education in general, was his argument that orators learn not only about the specifics of their case (the hypothesis) but also about the general questions from which they derived (the theses). Thus, in giving a speech in defense of a poet whose Roman citizenship had been questioned, the orator should examine not only the specifics of that poet's civic status, he should also examine the role and value of poetry and of literature more generally in Roman culture and political life. The orator, said Cicero, needed to be knowledgeable about all areas of human life and culture, including law, politics, history, literature, ethics, warfare, medicine, even arithmetic and geometry. Cicero gave rise to the idea that the "ideal orator" be well-versed in all branches of learning: an idea that was rendered as "liberal humanism," and that lives on today in liberal arts or general education requirements in colleges and universities around the world.

Rhetoric is the art of discourse, an art that aims to improve the capability of writers or speakers to inform, persuade, or motivate particular audiences in specific situations.[1] As a subject of formal study and a productive civic practice, rhetoric has played a central role in the Western tradition.[2] Its best known definition comes from Aristotle, who considers it a counterpart of both logic and politics, and calls it "the faculty of observing in any given case the available means of persuasion."[3] Rhetorics typically provide heuristics for understanding, discovering, and developing arguments for particular situations, such as Aristotle's three persuasive audience appeals, logos, pathos, and ethos. The five canons of rhetoric, which trace the traditional tasks in designing a persuasive speech, were first codified in classical Rome: invention, arrangement, style, memory, and delivery. Along with grammar and logic (or dialectic—see Martianus Capella), 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.[4] The word is derived from the Greek ῥητορικός rhētorikós, "oratorical",[5] from ῥήτωρ rhḗtōr, "public speaker",[6] related to ῥῆμα rhêma, "that which is said or spoken, word, saying",[7] and ultimately derived from the verb ἐρῶ erō, "I say, I speak".[8]
