Quintilian as a Literary Theorist: Early Life and Main Ideas

Marcus Fabius Quintilianus (c. 35 CE – c. 100 CE), commonly known as Quintilian, was a Roman rhetorician and educator whose enduring contribution to literary and rhetorical theory is embodied in his monumental twelve-volume treatise, Institutio Oratoria (“The Orator’s Education”).

Introduction

Marcus Fabius Quintilianus (c. 35 CE – c. 100 CE), commonly known as Quintilian, was a Roman rhetorician and educator whose enduring contribution to literary and rhetorical theory is embodied in his monumental twelve-volume treatise, Institutio Oratoria (“The Orator’s Education”). Born in Calagurris (modern Calahorra, Spain) and educated in Rome, Quintilian became one of the earliest scholars to systematize rhetoric as both an intellectual and moral discipline. His central theoretical premise—that the ideal orator must be “a good man skilled in speaking” (vir bonus dicendi peritus)—links eloquence with ethical integrity, thus merging linguistic artistry with civic virtue. Quintilian’s theory anticipates humanist thought by emphasizing moral character, pedagogical discipline, and the formative role of language in shaping reason and virtue. His literary criticism within Institutio Oratoria extends beyond technical rhetoric to encompass style, taste, and aesthetic judgment, influencing later theorists such as Erasmus and Milton. By combining Ciceronian eloquence with practical pedagogy, Quintilian established rhetoric as both an art of persuasion and a moral philosophy, shaping Western literary education for centuries.

Major Works and Rhetorical Contributions of Quintilian as a Literary Theorist

1. Institutio Oratoria (The Orator’s Education)

  • Main Work: Quintilian’s Institutio Oratoria (c. 95 CE) is his magnum opus, consisting of twelve books that collectively form the most comprehensive treatment of Roman rhetoric and education ever written.
  • Content Overview: It traces the ideal orator’s development from infancy through advanced rhetorical mastery, integrating moral, educational, and linguistic instruction (Quintilian, trans. Butler, 1920).
  • Key Idea: Quintilian insists that eloquence is inseparable from virtue—his famous dictum “vir bonus dicendi peritus” (“a good man skilled in speaking”) epitomizes this integration of ethics and eloquence (Quintilian, Book XII, Ch. 1).
  • Influence: The work profoundly shaped Renaissance and Enlightenment humanist education, inspiring figures such as Erasmus, Milton, and Locke to view rhetoric as both a moral and intellectual discipline (Murphy, 1987).

2. Ethical Foundation of Rhetoric

  • Moral Dimension: Quintilian diverged from the Sophistic tradition by grounding rhetoric in moral virtue rather than mere persuasion. For him, the orator must embody virtus, using speech for public good rather than manipulation (Kennedy, 1969).
  • Educational Implication: He proposed that moral character must precede rhetorical training—education should cultivate integrity and reason before stylistic flourish (Quintilian, trans. Butler, 1920).
  • Legacy: This ethical orientation redefined rhetoric as paideia—a formative discipline shaping both intellect and conscience—foreshadowing Christian and Renaissance pedagogical models (Murphy, 1987).

3. Theories of Style and Eloquence

  • Stylistic Hierarchies: Quintilian classified rhetorical style into three levels—plain (attenuata), middle (mediocris), and grand (gravis)—arguing for flexibility according to audience and purpose (Quintilian, Book XII).
  • Ideal Eloquence: He valued clarity (perspicuitas), propriety (decorum), and emotional resonance (movere) as hallmarks of great oratory (Kennedy, 1969).
  • Artistic Balance: His approach blended Ciceronian elegance with Aristotelian logic, balancing emotional appeal (pathos) with ethical credibility (ethos).

4. Pedagogical Model of Rhetoric

  • Progressive Education: Quintilian’s educational theory emphasizes gradual development—beginning with imitation and memory, advancing toward creative expression and critical reasoning (Murphy, 1987).
  • Teacher’s Role: He regarded teachers as moral exemplars who guide the student’s intellect and virtue alike (Quintilian, Book II).
  • Pedagogical Impact: His model influenced medieval trivium education (grammar, logic, rhetoric) and remains foundational in liberal arts pedagogy.

5. Contribution to Literary Criticism

  • Critical Evaluation: Quintilian analyzed classical authors (e.g., Cicero, Demosthenes, Homer, Virgil) not merely for style but for ethical and emotional integrity (Quintilian, Book X).
  • Canon Formation: He created one of the earliest systematic canons of literary excellence, linking critical judgment to moral education (Kennedy, 1969).
  • Enduring Legacy: His literary criticism established rhetorical criticism as a bridge between literature, philosophy, and ethics—laying groundwork for later humanist and neoclassical critics.

6. Influence on Humanist and Modern Rhetorical Theory

  • Humanism: Renaissance humanists revived Quintilian’s integration of eloquence and virtue, shaping the curricula of schools across Europe (Murphy, 1987).
  • Modern Communication Theory: His focus on audience psychology and moral responsibility continues to inform modern rhetorical studies and composition pedagogy (Kennedy, 1969).
  • Philosophical Relevance: Quintilian’s moral idealism anticipates Habermas’s notion of communicative ethics and discourse morality.

The Institutio Oratoria: Quintilian’s Masterpiece of Literary Theory

1. Overview of Institutio Oratoria

  • Full Title and Context: Institutio Oratoria (The Orator’s Education), written around 95 CE, is Quintilian’s twelve-volume magnum opus on rhetoric, education, and moral philosophy (Quintilian, trans. Butler, 1920).
  • Purpose: Designed as a complete guide to forming the ideal orator, it encompasses moral character, intellectual discipline, and artistic eloquence.
  • Scope: It is not merely a manual of oratory but a profound literary and pedagogical treatise—combining rhetorical technique, ethical instruction, and aesthetic judgment (Murphy, 1987).
  • Quotation: Quintilian declares, “It is the orator’s duty to speak well, and to form his style not merely with correctness but with beauty” (Quintilian, Inst. Orat., Book XII).

2. Moral Foundation of Rhetoric

  • Central Principle: Quintilian’s ideal orator must be “a good man skilled in speaking” (vir bonus dicendi peritus)—an ethical axiom that fuses virtue with eloquence (Quintilian, Book XII, Ch. 1).
  • Moral Education: He insists that education must first cultivate moral virtue before rhetorical skill: “Let the orator above all be a good man, for without goodness eloquence is dangerous” (Quintilian, Book XII).
  • Significance: This moral orientation distinguishes him from Sophists, positioning rhetoric as a tool for justice and civic duty rather than manipulation (Kennedy, 1969).

3. Educational Philosophy and Pedagogy

  • Developmental Model: Quintilian maps the learner’s growth from childhood to adulthood, integrating moral, linguistic, and aesthetic training.
  • Quotation: “From the very cradle, the education of the future orator must begin” (Quintilian, Book I, Ch. 1).
  • Pedagogical Vision: He champions early exposure to good models of speech and writing, advocating for patient, moral teachers who “love their pupils as sons” (Quintilian, Book II, Ch. 2).
  • Influence: His model shaped medieval and Renaissance education, establishing the rhetorical foundation of the liberal arts curriculum (Murphy, 1987).

4. The Art of Eloquence and Style

  • Three Levels of Style: Quintilian identifies plain (attenuata), middle (mediocris), and grand (gravis) styles, echoing Cicero’s stylistic hierarchy (Quintilian, Book XII).
  • Balanced Eloquence: He promotes decorum—the harmony between subject, style, and occasion—asserting, “The perfection of eloquence lies in adapting speech to circumstance” (Quintilian, Book XI).
  • Purpose of Eloquence: Eloquence, for Quintilian, is not ornamentation but ethical persuasion that enlightens and moves the audience (Kennedy, 1969).

5. Literary Criticism within Institutio Oratoria

  • Book X as a Canon: Book X presents one of the earliest systematic canons of classical literature, recommending Greek and Roman authors for imitation.
  • Critical Observation: He praises Cicero as the model of perfect eloquence, claiming, “Cicero stands alone among the orators; he gathers into one the excellences of all others” (Quintilian, Book X, Ch. 1).
  • Function of Criticism: For Quintilian, literary criticism is inseparable from ethical and aesthetic training—it develops both taste and virtue (Murphy, 1987).
  • Legacy: This critical canon guided European humanists and shaped early modern literary education.

6. The Orator as Philosopher and Citizen

  • Moral Statesmanship: Quintilian views the orator as a moral philosopher devoted to truth and justice: “The true orator must also be a good man, for virtue is the soul of eloquence” (Quintilian, Book XII, Ch. 2).
  • Civic Engagement: Eloquence is a social act—a form of ethical leadership that contributes to civic harmony (Kennedy, 1969).
  • Humanistic Ideal: This notion of the virtuous orator profoundly influenced Renaissance civic humanism and the ethical basis of Western education.

7. Legacy and Enduring Influence

  • Influence on Education: Quintilian’s pedagogical model became the foundation of medieval scholastic rhetoric and Renaissance humanist curricula.
  • Rehabilitation in Humanism: Erasmus and later rhetoricians revived Institutio Oratoria as a moral and literary guide for civic education (Murphy, 1987).
  • Modern Relevance: His synthesis of ethics, aesthetics, and communication theory prefigures modern concepts of discourse ethics and communicative rationality.
  • Quotation: “Rhetoric is the art of speaking well, not merely of persuading” (Quintilian, Book II)—a timeless assertion of moral eloquence.

Theoretical Terms/Concepts and Rhetorical Principles of Quintilian as a Literary Theorist

Theoretical Term / ConceptExplanationRepresentative Quotation / IdeaReference (APA 7th Edition)
1. Vir Bonus Dicendi Peritus (“A good man skilled in speaking”)Quintilian’s most famous principle linking morality with eloquence; the orator must be both virtuous and skilled in speech. This merges ethics and rhetoric into one unified discipline.“The good man, skilled in speaking, is the true orator; eloquence without virtue is the ruin of nations.” (Institutio Oratoria, Book XII, Ch. 1)Quintilian (1920); Kennedy (1969)
2. Eloquentia cum Virtute (Eloquence with Virtue)Eloquence is not mere persuasion but moral expression. Rhetoric must serve truth and justice, not deception.“It is the orator’s duty to speak well, and to form his style not merely with correctness but with beauty.” (Inst. Orat., XII)Quintilian (1920); Murphy (1987)
3. Decorum (Appropriateness)The principle that style and tone must suit the subject, audience, and occasion. It balances expression and context.“The perfection of eloquence lies in adapting speech to circumstance.” (Inst. Orat., XI)Quintilian (1920); Kennedy (1969)
4. Officium Oratoris (The Duty of the Orator)The orator’s responsibility is civic and ethical: to use speech for moral and social good, not self-interest.“The office of the orator is to speak well, for the public good.” (Inst. Orat., II, Ch. 16)Murphy (1987)
5. Imitatio (Imitation)Students should study and imitate great authors—especially Cicero and Demosthenes—to develop eloquence and taste.“By reading and imitating the masters, the orator will learn both to think and to speak well.” (Inst. Orat., X, Ch. 2)Quintilian (1920); Kennedy (1969)
6. Inventio, Dispositio, Elocutio, Memoria, PronuntiatioThe five canons of rhetoric: invention (finding arguments), arrangement, style, memory, and delivery—forming the structural basis of rhetoric.“Every speech consists of invention, arrangement, expression, memory, and delivery.” (Inst. Orat., III)Quintilian (1920)
7. Ethos, Pathos, LogosQuintilian integrates Aristotle’s triad but stresses ethos (character) as central to persuasion and moral credibility.“Character is the strongest argument; the audience believes the good man.” (Inst. Orat., VI)Kennedy (1969)
8. Docere, Delectare, Movere (“To teach, to delight, to move”)Rhetoric’s three aims: to instruct (docere), please (delectare), and move (movere) the audience. Quintilian refined Cicero’s formulation.“Let the orator both instruct the mind, please the ear, and move the heart.” (Inst. Orat., III, Ch. 5)Quintilian (1920); Murphy (1987)
9. Stilus (Style)Divides style into three levels—plain (attenuata), middle (mediocris), and grand (gravis)—each suited to different purposes.“There are three styles of speech: the restrained, the temperate, and the sublime.” (Inst. Orat., XII)Quintilian (1920)
10. Paideia (Education and Moral Formation)Education for Quintilian is moral, intellectual, and aesthetic; rhetoric trains both reason and virtue.“From the very cradle, the education of the future orator must begin.” (Inst. Orat., I)Murphy (1987)
11. Criticus Rhetor (The Orator as Critic)The orator must be a literary critic capable of judging authors and styles; Book X exemplifies this critical function.“We must learn not only to speak well but to judge what is well spoken.” (Inst. Orat., X, Ch. 1)Kennedy (1969)
12. Cura et Natura (Training and Nature)Eloquence arises from both natural talent (natura) and careful training (cura). Neither alone suffices.“Neither nature without training, nor training without nature, can produce the perfect orator.” (Inst. Orat., II)Quintilian (1920); Murphy (1987)
13. Virtus et Sapientia (Virtue and Wisdom)Rhetoric, for Quintilian, is founded on moral virtue and philosophical wisdom—linking it to Stoic ethics.“The true orator must also be a wise man, for wisdom governs speech.” (Inst. Orat., XII)Kennedy (1969)
14. Copia Verborum et Rerum (Abundance of Words and Ideas)Effective rhetoric requires mastery of both language and content; style must rest upon knowledge.“No man can speak well who knows not what he speaks of.” (Inst. Orat., II, Ch. 12)Quintilian (1920)
15. Iudicium (Critical Judgment)The ultimate aim of rhetorical education is iudicium—sound critical judgment that governs eloquence and ethics alike.“Judgment is the light of all speaking; without it, eloquence is blind.” (Inst. Orat., X)Murphy (1987)
Contribution to Classical and Modern Literary Criticism of Quintilian as a Literary Theorist

1. Classical Rhetorical Humanism

  • Modern Continuity: Contemporary stylistics continues his concern with language, tone, and audience adaptation (Kennedy, 1969).
  • Quotation: “The perfection of eloquence lies in adapting speech to circumstance” (Inst. Orat., XI).

7. Influence on Renaissance Humanism

  • Rebirth of Classical Education: Rediscovered in the 15th century, Institutio Oratoria became a foundational text for Renaissance pedagogy and literary criticism.
  • Humanist Application: Erasmus, Vives, and Melanchthon used Quintilian’s moral rhetoric to shape humanist curricula emphasizing eloquence, virtue, and civic responsibility (Murphy, 1987).
  • Quotation: “Rhetoric is not to deceive, but to instruct the mind and move the heart” (Inst. Orat., II.15).

8. Contribution to Modern Literary Criticism

  • Reference: (Murphy, 1987; Kennedy, 1969).

Criticism and Reassessment of Quintilian as a Literary Theorist

1. Overemphasis on Moralism

  • Critique: Many modern critics argue that Quintilian’s rhetorical theory is overly moralistic, subordinating artistic creativity to ethical restraint.
  • Issue: His insistence on vir bonus dicendi peritus (“a good man skilled in speaking”) limits rhetorical freedom by confining eloquence within moral virtue (Quintilian, Inst. Orat., XII.1).
  • Scholarly View: George A. Kennedy (1969) notes that Quintilian’s moral idealism, though noble, reduces rhetoric’s aesthetic autonomy and artistic experimentation.
  • Reassessment: Later critics reinterpret this moralism as a humanist attempt to reconcile art with civic responsibility rather than as a restriction on creativity.

2. Rhetoric as Pedagogy Rather Than Theory

  • Critique: Some scholars see Institutio Oratoria as primarily a pedagogical manual rather than a systematic literary theory.
  • Observation: Its step-by-step treatment of education, imitation, and style tends to emphasize instruction over critical philosophy (Murphy, 1987).
  • Reassessment: Modern rhetorical theorists, however, recognize Quintilian’s pedagogical model as a sophisticated fusion of philosophy, ethics, and literary theory—an early form of applied criticism.

3. Dependence on Classical Predecessors

  • Critique: Quintilian has been accused of derivative thinking, heavily reliant on Cicero and Aristotle for his theoretical framework.
  • Example: His divisions of style and five canons of rhetoric mirror earlier Greek formulations without substantial innovation (Kennedy, 1969).
  • Reassessment: Contemporary reassessment views this continuity as deliberate synthesis—Quintilian’s genius lay not in originality but in systematization, interpretation, and moral refinement of rhetorical tradition.

4. Limited Scope of Literary Canon

  • Critique: In Book X of Institutio Oratoria, Quintilian’s literary evaluations focus predominantly on Greco-Roman male authors, excluding women and non-classical traditions.
  • Modern View: Feminist and postcolonial critics see this as symptomatic of cultural exclusivity and rhetorical elitism.
  • Reassessment: Yet, within his Roman context, Quintilian’s canonization of moral and stylistic criteria helped preserve classical literature as a model for humanist education (Murphy, 1987).

5. Neglect of Emotional and Psychological Complexity

  • Critique: While Quintilian acknowledged pathos as part of persuasion, his moral rationalism often subdues the emotional and psychological dimensions of rhetoric.
  • Scholarly Note: Critics argue that his Stoic leanings led him to view emotion as something to control rather than explore (Kennedy, 1969).
  • Reassessment: Modern rhetorical psychology reinterprets this as proto-cognitive rhetoric—an early recognition of emotional discipline in effective discourse.

6. Ambiguity Between Philosophy and Practice

  • Critique: Quintilian’s fusion of ethics and eloquence produces tension between moral philosophy and pragmatic persuasion.
  • Issue: His orator must simultaneously be philosopher and public advocate—a dual role that may compromise practical effectiveness in politics or law.
  • Reassessment: Contemporary theorists like Wayne Booth and Kenneth Burke value this duality as an enduring model for ethical communication in modern criticism.

7. Underestimation in Modern Literary Studies

  • Critique: Despite his foundational role in rhetoric, Quintilian has been overshadowed in modern literary criticism by Aristotle’s Poetics and Cicero’s De Oratore.
  • Reason: Twentieth-century literary theory shifted toward structuralism and poststructuralism, leaving little room for moral-rhetorical traditions.
  • Reassessment: Recent scholarship in rhetorical studies and composition theory reclaims Quintilian as a precursor to ethical criticism and communicative rationality (Murphy, 1987).

8. Relevance to Modern Ethical Criticism

  • Reassessment: Modern critics reinterpret Quintilian’s work through the lens of ethical criticism, reader-response theory, and rhetorical humanism.
  • Contemporary Application: His idea that “eloquence must serve truth” aligns with Wayne Booth’s The Rhetoric of Fiction and Martha Nussbaum’s defense of moral imagination in literature.
  • Quotation: “Speech without moral purpose is an empty sound” (Inst. Orat., XII.5).
  • Scholarly Consensus: Quintilian’s ethical rhetoric anticipates modern debates about the social responsibility of critics and writers.

9. Postmodern Reinterpretation

  • Critique: Postmodern theorists challenge Quintilian’s universal moral standards as culturally constructed and exclusionary.
  • Reassessment: Yet scholars like James Murphy (1987) argue that Quintilian’s emphasis on ethical persuasion and interpretive judgment (iudicium) provides a stable framework in an age of relativism.
  • Modern Value: His moral universalism offers an enduring counterbalance to postmodern skepticism and linguistic nihilism.

10. Quintilian’s Lasting Relevance

  • Critical Reappraisal: Far from being obsolete, Quintilian’s integration of ethics, rhetoric, and education anticipates current interdisciplinary scholarship.
  • Legacy: His theories underpin contemporary discussions in moral criticism, civic discourse, and rhetorical pedagogy.
  • Conclusion: Quintilian’s literary theory, when reassessed through modern lenses, emerges not as static classicism but as a living dialogue between virtue, language, and human understanding.
