Are You Human? The Gom Jabbar Test Explained

You’ve heard of animals chewing off a leg to escape a trap? That’s an animal kind of trick. A human would remain in the trap, endure the pain, feigning death that he might kill the trapper and remove a threat to his kind.

What makes a human human? At first glance, this quote suggests a simple answer: unlike an animal, a human can master their own fear in a life-or-death moment. But this anecdote, used to introduce a Test of Humanity, hints at something far larger than an assessment of self-control… and the test itself—the Gom Jabbar Test, from Frank Herbert’s Dune—may not be aligned with the question it poses.

Let’s get this idea, undone.

---

Hello everyone, and welcome to Books Undone. I’m your host, Livia J. Elliot, and today we are analysing a single scene of Dune by Frank Herbert: the Gom Jabbar test, where Reverend Mother Gaius Helen Mohiam asks Paul Atreides to put his hand in a box that, arguably, contains nothing but pain. Were he to remove it, well… a poisoned needle will take his life on the spot. Extreme, isn’t it? But there was a reason for it.

This lethal test was administered to every candidate to Kwisatz Haderach—the almost messianic figure that the Bene Gesserit had attempted to breed for centuries. This man could usher in a new era for humanity, and so his capacities had to be well tested… except the test itself may be incomplete, and thus unable to evaluate both the necessary and the sufficient conditions for a leader’s character.

Before I can dive into this idea, allow me some housekeeping:

1. This episode focuses only, and exclusively, on the Gom Jabbar Test. If you are interested on the world of Dune, I have a podcast episode entirely dedicated to explaining the political structures and factions of this setting, and another one discussing the idea of scarcity through an economic lens. Likewise, I also hosted a conversation with other authors, which you may find interesting. You can find all of them at booksundone.com.
2. There are spoilers in this episode. I will stay focused on the Gom Jabbar test itself, but to explain some of my claims I will need to reveal the ending of Dune (the first book in the sextet) and imply long-term consequences.
3. That said, I am basing this analysis solely on the content of the novel. Do note that both adaptations do differ on their portrayal of the Gom Jabbar Test.
4. What follows is an interpretation, not a verdict. You may disagree, and that is another example of Dune’s philosophical richness.

With that said, allow me to begin by positing one question:

What is the Gom Jabbar Test?

To answer this deceptively simple question, we must first discuss the Bene Gesserit Order: a women-only organisation also known as the Sisterhood and, in my opinion, one of the most fascinating factions in the universe of Dune. Despite being led by a Reverend Mother, they are not a religious organisation. Internally, they function more like a school—inducting youngsters into their ranks and training them in a number of skills, including:

• Prana-Bindu (supreme control over every nerve and muscle in the body),
• the Voice (the ability to compel obedience in others by carefully calibrating the pitch and tone of one’s speech to a specific person), and
• the Weirding Way (a superior form of hand-to-hand combat built upon that same physical mastery)¹.

Why would they do this? Well, any organisation has goals, and so does the Sisterhood: in particular, to accrue power and influence in order to guide humanity towards insight and stability. To that end, and over the course of millennia, they have been conducting a meticulous breeding programme aimed at producing the Kwisatz Haderach: literally “the Shortening of the Way,” though later understood as “the one who can be in many places at once”—a male Bene Gesserit possessing all the so-called ‘right’ characteristics to lead humanity.

This programme led to Paul Atreides and, eventually, to his son Leto Atreides II… and whether that was a good outcome is a debate still raging among the readership.

The Gom Jabbar Test permitted Reverend Mothers to evaluate a specific set of attitudes on a candidate to Bene Gesserit—whether that was a woman joining the Sisterhood, or a possible Kwisatz Haderach. Yet to understand what those ‘specific attitudes’ it was testing for were, we need to first focus on…

The mechanics of the test.

In truth, we encounter the Gom Jabbar quite early in the novel, having almost no context as to whom the Bene Gesserit are nor what they are pursuing. It all begins when Paul Atreides overhears his mother—Lady Jessica, also a member of the Sisterhood—talking to Reverend Mother Gaius Helen Mohiam:

“He’s awake and listening to us,” said the old woman. “Sly little rascal.” She chuckled. “But royalty has need of slyness. And if he’s really the Kwisatz Haderach… well…"
Within the shadows of his bed, Paul held his eyes open to mere slits. Two bird-bright ovals—the eyes of the old woman—seemed to expand and glow as they stared into his.
“Sleep well, you sly little rascal,” said the old woman. “Tomorrow you’ll need all your faculties to meet my gom jabbar."

As foreshadowed, the actual test comes in the morning, when Lady Jessica leads Paul towards the library room where the Reverend Mother awaits. There, she uses the Voice to bring him closer and force him to his knees—then introduces the test like this:

“See this?” she asked. From the folds of her gown, she lifted a green metal cube about fifteen centimeters on a side. She turned it and Paul saw that one side was open—black and oddly frightening. No light penetrated that open blackness.
“Put your right hand in the box,” she said.
Fear shot through Paul. […] Slowly, feeling the compulsions and unable to inhibit them, Paul put his hand into the box. He felt first a sense of cold as the blackness closed around his hand, then slick metal against his fingers and a prickling as though his hand were asleep.
A predatory look filled the old woman’s features. She lifted her right hand away from the box and poised it close to the side of Paul’s neck. He saw a glint of metal there and started to turn toward it.
[…] “I hold at your neck the gom jabbar,” she said. “The gom jabbar, the high-handed enemy. It’s a needle with a drop of poison on its tip. Ah-ah! Don’t pull away or you’ll feel that poison."

At face value, the test is this: the Reverend Mother offers a box for the candidate to put their hand into, then holds a poisoned needle to their neck. This needle is the physical gom jabbar from which the test takes its name.

By now, you are probably wondering the same thing Paul asks: “What is in the box?” This is what the Reverend Mother tells him:

She bent close, lowered her voice almost to a whisper. “You will feel pain in this hand within the box. Pain. But! Withdraw the hand and I’ll touch your neck with my gom jabbar—the death so swift it’s like the fall of the headsman’s axe. Withdraw your hand and the gom jabbar takes you. Understand?"

The pain within the box begins as a tingling, but then it becomes an “itch” before progressing to “the faintest burning.” From there it grows and grows until it becomes mind-numbing.

Again, taking this at face value gives us a quick answer about the purpose of the Gom Jabbar Test: it could be assessing a candidate’s endurance of pain—except that, in Dune, there is always more than meets the eye, especially when it comes to the Bene Gesserit. To glimpse the truth behind this test, and why I claimed it to be incomplete, we must consider…

…the conversation that unfolds between Paul and the Reverend Mother as he endures it:

[Paul] felt increased tingling in his hand, pressed his lips tightly together. How could this be a test? he wondered. The tingling became an itch.
The [Reverend Mother] said: “You’ve heard of animals chewing off a leg to escape a trap? That’s an animal kind of trick. A human would remain in the trap, endure the pain, feigning death that he might kill the trapper and remove a threat to his kind."
The itch became the faintest burning. “Why are you doing this?” he demanded.
“To determine if you’re human. Be silent."

That response is why this is also referred to as The Test of Humanity: it is assessing whether the candidate to Bene Gesserit (or Kwisatz Haderach) is, well, human. Given that there are no alien species in the universe of Dune, we must assume that this ‘humanity’ is not a literal (or physical) trait, but a psychological one. This understanding could help us paraphrase the question I posited in the episode’s outset—what makes a human human?—into something perhaps more aligned to the test’s intentions: what psychological traits make a human worthy of being a Bene Gesserit and having a chance at leadership?

We can find the answer in the Reverend Mother’s comparison between an “animal” and a “human” reaction. There are three layers to her explanation. Evaluating them will help us discover what the test is missing.

The first layer is about suppressing the immediate reflex.

“You’ve heard of animals chewing off a leg to escape a trap? That’s an animal kind of trick” because “a human would remain in the trap.” Her choice of words implies a behavioural adaptation: an action or thing an animal does to survive and thrive.

If you think of it, the Gom Jabbar Test is, effectively, a life-or-death situation: Paul is trapped between the pain in the box (which continues to escalate into crippling levels) and the threat of a poisoned needle held at his neck. Situations such as this trigger an automatic reaction known as fight-or-flight—a behavioural adaptation we acquired in order to survive. But how does it work?

When we encounter a stressful or frightening situation, the amygdala—our brain’s fear centre—alerts the hypothalamus which, in turn, activates the sympathetic nervous system and initiates a chain reaction of physiological changes to give us the best chance of survival: adrenaline is released, our heart rate and blood pressure increase, the lungs dilate, our senses sharpen and digestion slows because it is not an essential function when you need to either kill your attacker or escape². This reaction has proven fundamental for animals to survive in the wild³—and because it is purely instinctive, it cannot be controlled: one cannot simply order the hypothalamus to stop releasing adrenaline; that’s not how it works.

But this is not a mere check to see whether a person’s behavioural adaptation still works or not; this links back to our ability to reason. While we cannot prevent the bodily reaction, we can somewhat control whether we act on it or not. This is why the Reverend Mother argues that “a human would remain in the trap”; because she’s asking Paul to go against his fight-or-flight response and keep his hand in the box while ignoring the poisoned needle at his neck.

This is not an easy task.

When our brain triggers a fight-or-flight response and the sympathetic nervous system takes control, it also diverts resources away from the prefrontal cortex… which is the part of the brain in charge of rational deliberation². Why? Because evolutionarily speaking, thinking does not help one survive situations where a split-second delay—such as a minor hesitation—could very well mean death.

The Reverend Mother’s comment demonstrates this lack of thinking. Remember she says:

You’ve heard of animals chewing off a leg to escape a trap? That’s an animal kind of trick.

If you imagine a common bear trap, the ragged circle that closes on a limb, chewing off a leg may be an animal’s only way of removing the trap and fleeing to safety. And yet… this impulsive reaction prevents this hypothetical animal from recognising that it may escape the immediate danger, but it may bleed to death soon after.

The problem is the animal’s reaction was driven by fear… which brings us, at last, to the Litany Against Fear—that chant to restore inner peace that the Bene Gesserit resort to in moments of stress. Given that Lady Jessica, Paul’s mother, was part of the Sisterhood, we can assume that she taught him the chant. Therefore, just after he places his hand inside the box and the pain creeps in, he begins to recite it:

[…] whatever it was, he knew himself caught in it, trapped by that hand at his neck: the gom jabbar. He recalled the response from the Litany Against Fear as his mother had taught him out of the Bene Gesserit rite.
I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain.
He felt calmness return, said: “Get on with it, old woman."
“Old woman!” she snapped. “You’ve courage, and that can’t be denied. Well, we shall see, sirra."

Many interpret the Litany as if it were saying that fear itself is deadly… but that may be too literal a reading of fear as the “mind-killer.” Instead, if we consider the “mind” as the faculty of judgement, choice, or awareness, we’d be surprisingly close to what the prefrontal cortex actually does—and, as we just discussed, that part of our brain is effectively shut down during a fight-or-flight response.

The next sentence of the Litany—“Fear is the little-death that brings total obliteration”—could very well refer to a physical death if we consider that “total obliteration” is the simultaneous demise of both mind and body. And how can fear kill the body? By driving someone towards simplistic decisions that ensure survival in the short-term (chew the leg off or pull the hand off the box) but kill in the long-term (bleed out later or be killed by the poisoned needle).

This is precisely why the first layer is about suppressing a fear-driven reaction: to not worsen the immediate situation, and thus have a chance to assess it. Such assessment would help the trapped victim to derive a better plan of action—something that perhaps has better mid- or long-term outcomes. If we look at the Reverend Mother’s example, what else can that animal do to remove the trap, that won’t make it bleed to death soon after?

The answer is:

The second layer in the Reverend Mother’s explanation: the reaction, and the reasons to act, should consider a different timescale.

Consider how her example continues:

A human would remain in the trap, endure the pain, feigning death that he might kill the trapper […]

While an animal reacts and chews its leg off merely to escape the trap—thus bleeding to death, or allowing whoever trapped it to attempt it again later—a human endures in order to act, consciously and willingly, later on: feign death, set a trap to the trapper, and kill them to remove the root of the threat. It is a logical sequence with clear steps and a clear goal (namely, safety in the long-term)… but it forces the ‘human’ to stay in that life-or-death situation for just a little longer.

This is what psychologists call delayed gratification: “the ability to resist the temptation of an immediate reward in favor of a more valuable and long-lasting reward later”⁴. It is not a capacity reserved for life-or-death situations—in fact, it is something we exercise daily. Consider someone who chooses to live well below their means for a year or two in order to save for a deposit on a property: they are resisting the temptation to spend freely, enduring a leaner life now, for the delayed reward of owning their own home.

Just like suppressing the reaction to fear in a life-or-death situation was no easy feat, delaying gratification is not easy either because it requires mastering self-regulation. To further complicate things, psychologist Albert Bandura⁵ argued that self-regulation is not a one-off act, but a continuously active process in which a person:

• (a) monitors their behaviour and what is influencing it, to
• (b) judge that behaviour according to personal and contextual standards, and then
• (c) reacts logically to one’s own behaviour—namely, the feelings and thoughts derived from it.

This overlaps almost perfectly with the Reverend Mother’s expectations during the Gom Jabbar Test: Paul had to monitor his behaviour (namely, recognise that fear of pain and death could influence his actions), judge his actions (because pulling the hand off the box is a delayed death sentence that doesn’t remove the actual threat), and then react according to the standards—namely, choosing to act in a way that removes the root of the threat. Never did she ask Paul not to fear; on the contrary, her expectation was to act rationally in spite of the fear.

In fact, the second half of the Litany Against Fear seems to circle the same idea. In particular, this part:

I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone, there will be nothing. Only I will remain.

Here, “I will permit [fear] to pass over me and through me” is about the monitoring stage of self-regulation: remaining aware of fear’s action in our body. Then, the next line—“And when it has gone past I will turn the inner eye to see its path”—is the second step Bandura proposed: judging the emotion-driven behaviour and its effects on us (poetically referred to as fear’s “path”). Finally, “Where the fear has gone, there will be nothing” implies a reaction… or better yet, the lack of an impulsive reaction, according to Bandura’s third step.

In this light, it is possible to argue that the Litany’s ending—“Only I will remain”—is not talking about heroic (yet meaningless) endurance, but about the supremacy of the self: what psychologists understand as “the cognitive, conative or affective representation of one’s identity”⁶, and philosophers argue pertains to an individual’s own being, knowledge, and values. Therefore, if fear is the “mind-killer” in the sense of shutting down rational deliberation, then what “remains” after fear passes through is exactly that faculty restored—the capacity for judgement, choice, awareness. In other words, the third step of self-regulation: choosing to act in a way supported by the values conforming our identity.

This is why, according to the Reverend Mother Helen Mohiam, the second layer of intention in the Gom Jabbar Test is about whether the person being tested can reason logically, in spite of the fear, to discover a long-term gain, then craft and implement a strategy to secure it. For the case example she mentions, that gain would not be to just merely escape the trap, but to kill the trapper.

But… is the Gom Jabbar Test actually evaluating this? Here is where its incompleteness begin to appear:

• The first layer is measured directly through the mechanics of the test: Paul must control his instinct to not pull the hand off the box (done to avoid the pain), or the poisoned needle would kill him. This matches the Reverend Mother’s example perfectly. However…

• The second layer is measured indirectly. We know that the Gom Jabbar Test was administered to Bene Gesserit candidates—young ladies who, where they to surpass this hurdle, would gain access to education, training, and political placements that would not be available to them otherwise. These were the long-term gains the Reverend Mother’s speech implied, and it is not far-fetched to assume anyone passing this test would want access to those benefits.

• But what about the third layer? What is it and how is it evaluated? In truth…

The third layer—who and why to act for—is not being assessed, neither directly nor indirectly.

This is why I claimed the Gom Jabbar Test to be incomplete. Consider how the Reverend Mother’s example ends:

A human would remain in the trap, endure the pain, feigning death that he might kill the trapper and remove a threat to his kind.

The Reverend Mother is telling Paul that the long-term strategy that a “human” must aim for—that delayed gratification they must seek—should be beneficial to “his kind”, such as family, soldiers, or even those he leads… but not necessarily to himself, for she never implies Paul should survive. Her choice of words is, of course, deliberate: she’s making the calculus of long-term gains social and evolutionary rather than merely personal.

If you recall, we established that the Bene Gesserit Order has one specific goal: to accrue power and influence to guide humanity towards insight and stability. Regardless of the moral or ethical assessment of their means to achieve such a goal, it becomes clear that they are trying to produce people—either women to join the Sisterhood, o men as candidates for Kwisatz Haderach—that are capable of subordinating the strongest biological imperative (self-preservation) to a larger, consciously chosen objective that will favour others.

And isn’t that what a good leader should do? Place the well-being of those they lead above their own?

However, the Gom Jabbar Test does not cover this layer of intent. While the Reverend Mother’s anecdote implies the test is evaluating it, the mechanics simply do not. One may assume that she may have attempted to condition Paul (given the conversation in the aftermath of the test), or that a Sisterhood acolyte will be tested further on, while being educated by the Order… but this cannot be thought of Paul’s case.

This is why, at the start of the episode, I dared to posit that the Gom Jabbar Test was incomplete:

• because it can only ever assess whether someone has the necessary condition for leadership (the raw executive capacity to subordinate the instinctive reactions of self-preservation to a chosen goal), but
• cannot test for the sufficient condition (that this someone will actually aim his capacity towards the benefit of “his kind” rather than of himself).

To me this is not a weakness of the scene, and neither a so-called ‘plot-hole’. In fact, I’ll argue that Frank Herbert deliberately planned for the Test of Humanity to be incomplete because the Sisterhood is betting that centuries of selective breeding and doctrine will have pointed this human capacity toward achieving insight and stability for all of humanity.

But that expectation… is nothing more than an assumption.

Let us consider the aftermath, then. What happens after Paul passes the Gom Jabbar Test.

There is a brief exchange between the Reverend Mother Gaius Helen Mohiam and Paul Atreides:

He lifted his right hand, willing the memory of the pain. “And that’s all there is to it—pain?"
“I observed you in pain, lad. Pain’s merely the axis of the test. Your mother’s told you about our ways of observing. I see the signs of her teaching in you. Our test is crisis and observation."
He heard the confirmation in her voice, said: “It’s truth!"
She stared at him. He senses truth! Could he be the one? Could he truly be the one? She extinguished the excitement, reminding herself: Hope clouds observation.
“You know when people believe what they say,” she said.
“I know it."
The harmonics of ability confirmed by repeated test were in his voice. She heard them, said: “Perhaps you are the Kwisatz Haderach. Sit down, little brother, here at my feet."

There is much to unpack in this exchange, so let us begin with the Reverend Mother’s latest disclosure about the test:

Pain’s merely the axis of the test. Your mother’s told you about our ways of observing. I see the signs of her teaching in you.

What we gather from her words seems straightforward: the test had two components. Namely:

1. What the person being tested did (namely, his actions), and
2. What the one administering the test observed in the former during the test.

Crisis and observation; set the trap, and watch the prey solve it. But what if the scene—and that conversation in the aftermath—was deliberately presented to hint at the Test’s flaws? What if the scene shows two characters who passed the Gom Jabbar Test and had the necessary conditions for leadership, but not the sufficient ones? Worse off, what if I tell you those two characters are Paul Atreides… and the Reverend Mother herself?

How could they both have failed?

The key to answer this question lies in the second component of the test: the observation. The Reverend Mother confirms this—besides plunging the poisoned needle into Paul’s neck, where he to fail—that observing was her key task during the assessment:

“I observed you in pain, lad. […] I see the signs of [you mother’s] teachings in you."

At a first glance, this seems… a simple task. However, we know very well that the Reverend Mother is not a common woman:

1. First, she is a Bene Gesserit, and therefore proficient on all their skills—including petit perception, which allowed a Sister to monitor minutiae in others to detect concealed emotions, motivations, and agendas.
2. Second, within Dune, Reverend Mothers have access to the other memories—the literal memories of her previous female ancestors now alive and accessible within her.

Therefore, when the Reverend Mother disclosed to have been “observing”, we can confidently assume it was far beyond what a regular person could gather. She was likely appealing to petit perception while possibly hearing the other memories to draw conclusions about Paul’s character. Does this mean her thorough observation compensated for what the Gom Jabbar did not test, neither directly nor indirectly—the third layer we discussed? Could everything have depended on her ability to detect whether Paul could act for the benefit of others?

The novel does not give us an answer, but we know she did made some thorough observations that even caught some of Paul’s thoughts, for she caught the moment Paul thought about the Litany Against Fear:

”[…] Your mother’s told you about our ways of observing. I see the signs of her teaching in you. […]"

But she doesn’t merely think of this—she says the words to Paul… and this seemingly innocent slip, enables a very interesting response from him:

[Paul] heard the confirmation in her voice, said: “It’s truth!"

This is not clunky phrasing and neither a stylistic choice of prose. In reality, Herbert was pointedly indicating that Paul has truthsense: the in-universe ability to unequivocally detect the truth in someone’s spoken words. Truthsense was a skill developed and used by the Bene Gesserit, though some individuals outside the Sisterhood were naturally born with it… and to further complicate the situation, the Bene Gesserit believed the Kwisatz Haderach would have truthsense.

I f you recall, Paul is undertaking the Gom Jabbar Test because his mother, Lady Jessica, believed he could be the one.

The Reverend Mother seemed to be healthily suspicious of Jessica’s beliefs, so when Paul demonstrated his truthsense she… was caught off guard. Her surprise, unfortunately, derailed her in-depth observation of his reaction (and thus leaving the Test incomplete) towards considering the very real possibility that the Sisterhood’s ambitions may finally be achieved:

She stared at him. He senses truth! Could he be the one? Could he truly be the one? She extinguished the excitement, reminding herself: Hope clouds observation.

This is the moment when the Reverend Mother shows that she, herself, had the necessary conditions for leadership, but not the sufficient one—even though she’d passed both her own Gom Jabbar and the more complex test that allowed her to achieve the position of Reverend Mother. Consider her reactions and behaviours in light of the three layers of the Test of Humanity:

1. First, she showed self-mastery and remained focused on observing Paul even when her instinct could have compelled her to stop his suffering. This was the first layer: suppress the instinct.
2. Second, she enabled Paul’s suffering for the possible long-term benefit of actually finding the Kwisatz Haderach—exactly what the second layer means. But…
3. Third, she became distracted by power instead of virtue allowing her own automatic reactions to distract her from the task at hand; in her own words, “Hope clouds observation”. A task that served the broader Bene Gesserit goals of preventing someone without the sufficient condition from accessing all the abilities associated to the Kwizatz Haderach—after all, this Test was administered on the eve of the Atreides departure to Arrakis, the day after Paul had been made aware of the dangers of the desert planet home to the spice.

This is the irony of the Gom Jabbar’s incompleteness: the rite of passage that is supposed to certify Paul’s capacity to subordinate his self-interest to a larger goal in benefit of others is immediately followed by Mohiam failing to do exactly that herself. The test asks Paul to override reflex in service of a purpose beyond himself while, in the same scene, Mohiam is asked—by her own Order’s discipline—to override her hope and ambition in service of clear-eyed observation… and she only half-manages it. The very woman certifying the third layer was present was caught failing it.

Which brings me to a last question:

What can confirm the sufficient condition for leadership? That one would always act in the benefit of others?

The honest answer, textually, is that nothing does.

Throughout Dune, Herbert repeatedly complicates the idea that acting for “humanity” is morally straightforward. On the one hand you could argue that Paul was attempting to help the Fremen be rid of the Harkonnen oppression, to even assist the Landsraad—the organisation grouping all Noble Houses—to rid itself of the Spacing Guild’s unilateral control of spice… but on the other hand, one can argue his own reasons are quite selfish. This is what Paul claims while trying to rouse the Fremen to follow him;

“Who rules here?” Paul asked. He raised his fist. “I rule here! I rule on every square inch of Arrakis! This is my ducal fief whether the Emperor says yea or nay! He gave it to my father and it comes to me through my father!"
Paul lifted himself onto his toes, settled back to his heels. He studied the crowd, feeling their temper.
Almost, he thought.
“There are men here who will hold positions of importance on Arrakis when I claim those Imperial rights which are mine,” Paul said. “Stilgar is one of those men. Not because I wish to bribe him! Not out of gratitude, though I’m one of many here who owe him life for life. No! But because he’s wise and strong. Because he governs this troop by his own intelligence and not just by rules. Do you think me stupid? Do you think I’ll cut off my right arm and leave it bloody on the floor of this cavern just to provide you with a circus?"

He corrected his reasons half-way through the speech because he noticed that—in modern terms—his words were not landing fully with his audience. This is not what one thinks when imagining a leader that ‘acts in the benefit of those he leads’. On the contrary it reads as someone who knows what to tell an audience in order to convince them to follow.

Furthermore, the ending of Dune—the first book—is damning, showing that Pual never had the sufficient condition. In short, Paul forces Princess Irulan (the Emperor’s daughter) to marry him in order to become Emperor, exiles his now father-in-law to a distant planet, then threatens to destroy the spice in order to subdue the Spacing Guild’s immediate rejection… and, because he was aware of the forceful way he became Emperor, begins a Jihad across the universe so that his position would be acknowledged by the other Houses of the Landsraad. This Jihad uses, as the main military force, the Fremen—the very same people who believed him to be a messianic saviour.

What we see here is that the Gom Jabbar test corroborates that a human has one necessary capacity—placing long-term interests above immediate instinct—but… it deliberately leaves open the question of whether those goals are pursued for the benefit of others, and whether they are ultimately wise and just.

This is one of Herbert’s recurring themes. Self-mastery is necessary, but it isn’t enough to be a leader. Someone—a human—can possess extraordinary control over instinct and still direct that control toward catastrophic ends.

Dune, what a complex book; so much more than science fiction. If you liked this episode, you may want to check my other episodes discussing Herbert’s work:

• I have a very thorough analysis of the underlying political theory in the first book, which also covers the different factions, the tensions between them, and the causes for war within this universe. This also dives into how engineered religion can be used to legitimise political power.
• In another episode, I discussed Arrakis’ water scarcity through an economic lens… and contrasted that to the scarcity of Do Androids Dream of Electric Sheep?, the book upon which Blade Runner was based.
• Finally, I also have a conversation with other authors discussing Dune, where we touched on religion as technology, Irulan’s role in storytelling Paul’s actions, and more.

You can find all the episodes in booksundone.com. And if highly thematic books with complex political settings interest you, please check the first book in my own series, The Omens of War; it is available wide in ebook and paperback, so I’ll leave all links in the episode’s description.

Thanks for listening, and happy reading.
