Book: A Grammar of Motives

Overview

Kenneth Burke's A Grammar of Motives reimagines human action as fundamentally rhetorical and dramatistic, proposing a vocabulary for analyzing how people attribute motives. Burke argues that the ways people describe actions, situations, agents, means, and ends are not neutral reports of inner states but symbolic constructions that shape understanding and responsibility. The book offers a systematic toolkit for tracing how motive is framed, contested, and transformed across discourse.

The Dramatistic Pentad

Central to Burke's scheme is the dramatistic pentad: act, scene, agent, agency, and purpose. Each term functions as a dimension through which motive can be described: "act" names what was done, "scene" situates where and when, "agent" identifies who acted, "agency" specifies how the act was accomplished, and "purpose" gives the intended end. Burke shows how different emphases among these terms lead observers to locate cause differently, whether in character, context, instrumentality, or intention.

Ratios and Shifts of Emphasis

Burke introduces the idea of "ratios" to analyze the interplay between pentadic terms, demonstrating how coupling one term with another alters causal ascriptions. A scene-act ratio, for example, emphasizes environmental determinism, while an agent-act ratio foregrounds will or character. By examining which ratio a speaker or text privileges, the analyst can reveal underlying worldviews, rhetorical aims, and shifts in blame or credit as discourse moves between explanations.

Motives as Symbolic Constructions

For Burke, motives are not mere psychic causes but symbolic frameworks that make action intelligible and socially consequential. Language selects and deflects realities; the metaphors and syntactic choices available to speakers function as "terminology" that directs attention and shapes identity. Motives thus emerge through symbolic arrangements that can both liberate and constrain, enabling identification, persuasion, and the denial or acceptance of responsibility.

Method for Criticism

A Grammar of Motives offers a practical method for rhetorical criticism: map the pentadic terms within a text or situation, note dominant ratios and recurring clusters of terms, and observe what has been foregrounded or silenced as motive. This method helps expose equivocations, strategic framing, and implicit moral hierarchies. Burke encourages flexible application of the pentad to political speeches, literary works, everyday explanations, and institutional narratives in order to uncover how audiences are led to interpret actions.

Significance and Influence

Burke's dramatistic approach reframed rhetorical studies by treating human behavior as language-mediated drama rather than as raw psychological data. The pentad became a durable heuristic for scholars interested in ideology, responsibility, and persuasion, influencing criticism, communication theory, and cultural analysis. By focusing attention on how motives are articulated and contested, the book opens pathways to understanding not only why people act but how language mobilizes motives to shape social life.
