Jack Burden's theory of the "Great Twitch," the idea that human behavior might be nothing more than involuntary nerve impulses rather than the product of genuine moral choice, introduces a genuinely philosophical dimension to All the King's Men that goes well beyond its political narrative. This theory offers Jack a convenient way to avoid moral responsibility for his own choices, including his role in gathering the information that leads to Judge Irwin's suicide, by framing all human action as essentially involuntary and therefore beyond meaningful judgment. An essay assignment built around this theory gives students the opportunity to engage with genuine philosophical questions about determinism and free will while remaining grounded in specific literary evidence. This kind of assignment works particularly well in classes that also touch on philosophy or that want to build cross-disciplinary connections between literature and other humanities subjects.

Before assigning this essay, it helps to give students some basic grounding in the philosophical concept of determinism, ideally through a brief, accessible explanation rather than a full academic treatment, so they understand the "Great Twitch" theory within its broader intellectual context rather than treating it as an isolated, novel-specific idea. Understanding that Jack's theory echoes real philosophical debates about whether human choices are truly free or simply the result of prior causes, whether biological, psychological, or social, helps students see the theory as engaging with genuine, serious questions rather than dismissing it as merely a character's excuse. This grounding also helps students recognize that the novel does not simply endorse or reject the theory outright, but rather dramatizes its consequences through Jack's own moral journey across the narrative.

The most important textual evidence for this essay comes from tracking whether and how Jack's relationship to the "Great Twitch" theory changes over the course of the novel, particularly in its final chapters where he appears to move toward a more engaged, responsibility-accepting worldview. Students should be encouraged to locate the specific moment or moments where this shift becomes apparent, whether through Jack's changed relationship with Anne Stanton, his decision to care for the elder Judge Irwin's memory, or his final reflections on entering "the awful responsibility of Time." This kind of before-and-after tracking gives the essay a clear analytical structure while requiring genuine close reading across the full length of the novel rather than a single isolated passage.

Framing a Strong Philosophical Prompt

A strong prompt for this assignment might ask students to argue whether the novel ultimately validates or rejects the "Great Twitch" theory as a genuine account of human behavior, using Jack's full character arc as evidence. This framing requires students to move beyond simply explaining what the theory is and toward making a genuine interpretive claim about the novel's overall philosophical position, which is a significantly more demanding and rewarding analytical task. An alternative version of the prompt might ask students to consider whether the novel suggests that believing in determinism, regardless of whether it is philosophically true, has harmful practical consequences for how a person treats others, using Jack's complicity in Judge Irwin's downfall as a central piece of evidence. Both versions push students toward genuine philosophical argumentation grounded in specific textual detail.

• Explains the "Great Twitch" theory accurately, connecting it to Jack Burden's specific psychological situation
• Tracks whether and how Jack's relationship to the theory changes across the novel
• Makes a clear claim about whether the novel validates, rejects, or complicates the theory
• Uses Jack's treatment of Judge Irwin, Anne Stanton, or his mother as specific supporting evidence
• Avoids treating the theory as simply a plot device separate from the novel's larger philosophical argument

Grading for Philosophical Rigor

When grading these essays, it is worth distinguishing between students who genuinely engage with the philosophical stakes of the "Great Twitch" theory and students who treat it more superficially as simply a character quirk or an excuse for Jack's passivity without exploring its deeper implications. Strong essays should demonstrate an understanding that the theory raises real questions about moral responsibility that extend beyond Jack's individual situation, connecting to broader debates about whether people can be held accountable for actions shaped by forces beyond their immediate control. Essays that engage with this broader philosophical weight, even briefly, tend to demonstrate a more sophisticated understanding of the novel's intellectual ambitions than essays that treat the theory purely as plot mechanics specific to one character's psychology.

It is also worth watching for essays that correctly identify Jack's eventual movement away from strict determinism but fail to explain what specifically causes that shift, missing an opportunity for genuinely rich causal analysis. The novel does not present Jack's change as sudden or fully explained by a single event; rather, it accumulates through his relationships and experiences, particularly his reconciliation with Anne Stanton and his confrontation with the consequences of his own actions regarding Judge Irwin. Essays that trace this gradual accumulation, rather than pointing to a single moment as a complete explanation, demonstrate a more careful and accurate reading of how the novel actually handles Jack's philosophical and moral development.

Connecting to Broader Curriculum Goals

This essay assignment offers a valuable opportunity to connect literary analysis with broader critical thinking skills around causation, responsibility, and the relationship between belief and action, skills that extend well beyond the immediate context of this single novel. Framing the assignment explicitly as an exercise in philosophical reasoning grounded in literary evidence, rather than purely as a literature assignment, can help students see connections to other coursework in philosophy, psychology, or ethics that they may be taking concurrently or will encounter later in their education. This kind of explicit interdisciplinary framing tends to increase student engagement, particularly among students who might otherwise see literary analysis as disconnected from more "practical" or "real-world" thinking skills.

Finally, teachers should be prepared for a wide range of genuinely thoughtful, well-supported positions on this essay, since the novel itself does not offer an unambiguous resolution to the philosophical question it raises through Jack's theory. Some students will argue convincingly that Jack's final embrace of responsibility fully rejects the "Great Twitch" theory, while others will argue equally convincingly that the novel remains more ambiguous, suggesting Jack has simply found it psychologically necessary to believe in free will regardless of whether it is philosophically true. Both positions, when well-supported with specific textual evidence, represent legitimate and sophisticated engagement with one of the novel's most intellectually demanding threads, and grading should reflect that genuine interpretive openness.
