01·Who they are
Who is IT (the Black Brain)?
IT is the supreme intelligence of Camazotz, introduced in Chapter 8 ("The Transparent Column") and confronted directly in Chapter 9 ("IT"). Physically, IT is a disembodied brain of monstrous scale — grey, pulsating, repulsive — housed in a column in the CENTRAL Central Intelligence building. Yet IT's body is almost beside the point: its real existence is the rhythmic heartbeat that radiates outward across an entire planet, synchronizing every thought, every action, every will into a single mechanical pulse. IT does not merely command Camazotz; IT is Camazotz. The inhabitants do not obey IT so much as they have been dissolved into it. L'Engle presents IT not as a tyrant who seizes power through violence but as a philosophical endpoint — what happens when the desire for order, comfort, and freedom from pain is taken to its absolute, annihilating conclusion. IT is the novel's most disturbing creation precisely because it offers something genuinely tempting: the end of suffering, uncertainty, and loneliness. The cost is everything that makes a person a person.
02·Arc & motivation
What is IT (the Black Brain)'s arc and motivation?
IT does not change — and that is the point. Where protagonists grow through doubt and love, IT is static perfection, a closed loop. Its motivation is total absorption: IT cannot tolerate the existence of a mind that thinks differently, because difference represents a kind of chaos IT is constitutionally incapable of understanding. IT's "arc" is therefore the arc of its victims' resistance. It begins as an ambient, invisible force expressed through eerie communal uniformity — children bouncing balls in unison, mothers opening doors at exactly the same moment in Chapter 6 ("The Happy Medium"). It escalates through the Man with Red Eyes, then reaches its apex when it possesses Charles Wallace, turning the most gifted mind among the children into its most eloquent instrument. IT's only movement is toward greater totality. The defeat it suffers at the novel's end is not a transformation but an exposure: Meg's love does not destroy IT so much as reveal the absolute limit of what pure intellect without feeling can comprehend.
03·Key moments
What are IT (the Black Brain)'s key moments?
- The bouncing balls (Chapter 6): The children's first visceral encounter with IT's influence — not IT itself, but the eerie mechanical sameness of Camazotz's suburban streets. One child who bounces out of rhythm is dragged indoors, foreshadowing the violence beneath the compliance.
- The Man with Red Eyes (Chapter 8): IT's puppet attempts hypnotic persuasion, speaking in a smooth, reasonable voice about happiness and freedom from pain. This scene establishes IT's central ideological seduction: conformity as mercy.
- Possession of Charles Wallace (Chapter 9): IT exploits Charles Wallace's extraordinary mental openness to subsume him completely. The moment is the emotional turning point of the novel — Charles Wallace's eyes go "opaque," his voice becomes a cold, mocking instrument, and Meg loses her brother to a force that now wears his face.
- The direct confrontation (Chapter 9): Meg, Calvin, and Mr. Murry face IT and nearly succumb. The pulsating rhythm is almost irresistible; Meg saves herself only by reciting mathematical tables, a fragile intellectual counter-rhythm that barely holds.
- Meg's return and IT's defeat (Chapter 12): Sent back alone, Meg finds the one weapon IT cannot process — unconditional love for Charles Wallace. She floods her brother with it, and IT, unable to replicate or counter an emotional force outside its rational framework, loses its grip.

04·Relationships
What are IT (the Black Brain)'s most important relationships?
IT's relationship with Charles Wallace is the novel's emotional core. Charles Wallace's gifts — his telepathy, his radical openness to other minds — are precisely what make him IT's most valuable and most vulnerable target. IT turns his extraordinary empathy into a weapon against the people he loves most, and L'Engle makes the horror intimate: Meg must fight for her brother through his own face and voice. Meg functions as IT's antithesis. Her faults — stubbornness, fierce emotional attachment, impatience with cold logic — are precisely the qualities IT cannot absorb or understand. The Man with Red Eyes reveals IT's preferred method of conquest: gradual persuasion, the language of reason and comfort, before outright compulsion. Mr. Murry's inability to free Charles Wallace even after his own rescue is crucial — it demonstrates that intelligence and love of family are insufficient alone against IT; something beyond rational resistance is required. The three celestial guides (Mrs. Whatsit, Mrs. Who, Mrs. Which) function as IT's cosmic counterweights, their very nature — joyful, individuated, strange — the opposite of IT's flattening uniformity.

06·Questions
Questions readers ask about IT (the Black Brain)
What is IT in A Wrinkle in Time?
IT is a disembodied, pulsating brain that acts as the supreme malevolent intelligence of the dark planet Camazotz. Housed in the CENTRAL Central Intelligence building, IT rules not through violence but via a rhythmic heartbeat that synchronizes every thought and action of the inhabitants into a single mechanical uniformity, obliterating all free will and individuality.
How does IT control Camazotz and its inhabitants?
IT controls Camazotz through a hypnotic, pulsating rhythm that dissolves individual thought into collective synchronization. Inhabitants are absorbed into IT — children bounce balls in perfect unison, mothers open doors at the same moment, and any deviation is swiftly punished. IT also operates through human puppets, most notably the Man with Red Eyes, who uses persuasion before outright compulsion takes hold.
Why does IT target Charles Wallace specifically?
IT targets Charles Wallace because his extraordinary telepathic openness — the very gift that makes him exceptional — leaves him uniquely vulnerable to possession. By exploiting his receptivity to other minds, IT fully subsumes him in Chapter 9, turning his intelligence and voice into a cold, mocking instrument used to taunt Meg and draw the group deeper into IT's control. His gifts become the precise mechanism of his capture.
What is IT's relationship with Meg Murry?
Meg is IT's ultimate nemesis, and the qualities that make her seem flawed — stubborn emotionality, fierce attachment, impatience with cold logic — are precisely what IT cannot absorb or understand. When Meg returns to Camazotz alone in Chapter 12 and floods Charles Wallace with unconditional love, IT is powerless to replicate or counter it, revealing that IT's purely rational dominion has a critical blind spot: genuine human feeling.
How is IT defeated at the end of A Wrinkle in Time?
IT is defeated in Chapter 12 when Meg returns to Camazotz alone and overwhelms Charles Wallace with fierce, unconditional love. Because IT's intelligence is entirely rational and conformist, it literally cannot process or counter an emotional force outside its framework. IT does not transform or die — it simply loses its grip on Charles Wallace, exposing the absolute limit of what pure intellect without feeling can comprehend or control.
Does IT have any famous quoted lines in the novel?
No direct lines are attributed to IT in the novel's text — IT does not speak independently. Instead, IT communicates through possessed vessels, most chillingly through Charles Wallace, whose voice becomes a cold, mocking instrument after his possession in Chapter 9. This ventriloquism is part of IT's horror: it has no authentic voice of its own, only stolen ones.
Is IT purely evil, or does L'Engle suggest it has any appeal?
L'Engle deliberately makes IT appealing as well as terrifying. Through the Man with Red Eyes, IT argues in smooth, reasonable language that it offers freedom from pain, uncertainty, and loneliness — and that conformity is a form of mercy. IT represents the philosophical endpoint of sacrificing individual freedom for collective comfort, making it disturbing precisely because the trade it offers is genuinely tempting before one reckons with what is lost.
Why can't Mr. Murry free Charles Wallace from IT's control?
Mr. Murry cannot free Charles Wallace because intelligence and love of family alone are insufficient against IT. His rescue by Meg triggers the group's desperate tessering escape, but IT's hold on Charles Wallace remains intact, demonstrating L'Engle's argument that rational resistance — however well-intentioned — cannot match IT. Something beyond intellect, specifically Meg's unconditional love, is needed to break IT's possession.
