Summary
The quadrant is the navigational instrument that measures the sun's angle to determine latitude—where you are on the globe. Ahab, increasingly consumed by his obsession, performs his daily noon measurement on deck. But today, something snaps. As he peers through the device at the sun, he suddenly hurls it to the deck and tramples it to pieces, declaring he'll no longer be guided by the heavens. He rejects the sun itself, calling it a 'high and mighty pilot' that mocks him. From now on, he'll navigate by compass and log-line alone—dead reckoning, the old way, without celestial guidance. The crew watches in horror as their captain literally destroys the tool that tells them where they are in the vast Pacific. Starbuck sees this as the final proof of Ahab's madness—destroying the very instrument that could guide them home. But Ahab sees it differently. The sun, the stars, the heavens themselves—they're all part of the natural order that created the white whale. By rejecting celestial navigation, Ahab declares independence from God's universe itself. He'll chart his own course now, guided only by his iron will and the compass needle pointing toward his revenge. It's a moment of supreme defiance that leaves the crew understanding they're now sailing with a captain who has declared war not just on a whale, but on the very order of creation. The Pequod is now truly unmoored—not just from land, but from the heavens that guide all ships home.
Coming Up in Chapter 119
With the quadrant destroyed and celestial navigation rejected, how will Ahab guide the Pequod through the vast Pacific? The answer involves an almost supernatural connection between hunter and hunted.

An excerpt from the original text.(~500 words)
The Quadrant. The season for the Line at length drew near; and every day when Ahab, coming from his cabin, cast his eyes aloft, the vigilant helmsman would ostentatiously handle his spokes, and the eager mariners quickly run to the braces, and would stand there with all their eyes centrally fixed on the nailed doubloon; impatient for the order to point the ship’s prow for the equator. In good time the order came. It was hard upon high noon; and Ahab, seated in the bows of his high-hoisted boat, was about taking his wonted daily observation of the sun to determine his latitude. Now, in that Japanese sea, the days in summer are as freshets of effulgences. That unblinkingly vivid Japanese sun seems the blazing focus of the glassy ocean’s immeasurable burning-glass. The sky looks lacquered; clouds there are none; the horizon floats; and this nakedness of unrelieved radiance is as the insufferable splendors of God’s throne. Well that Ahab’s quadrant was furnished with coloured glasses, through which to take sight of that solar fire. So, swinging his seated form to the roll of the ship, and with his astrological-looking instrument placed to his eye, he remained in that posture for some moments to catch the precise instant when the sun should gain its precise meridian. Meantime while his whole attention was absorbed, the Parsee was kneeling beneath him on the ship’s deck, and with face thrown up like Ahab’s, was eyeing the same sun with him; only the lids of his eyes half hooded their orbs, and his wild face was subdued to an earthly passionlessness. At length the desired observation was taken; and with his pencil upon his ivory leg, Ahab soon calculated what his latitude must be at that precise instant. Then falling into a moment’s revery, he again looked up towards the sun and murmured to himself: “Thou sea-mark! thou high and mighty Pilot! thou tellest me truly where I _am_—but canst thou cast the least hint where I _shall_ be? Or canst thou tell where some other thing besides me is this moment living? Where is Moby Dick? This instant thou must be eyeing him. These eyes of mine look into the very eye that is even now beholding him; aye, and into the eye that is even now equally beholding the objects on the unknown, thither side of thee, thou sun!” Then gazing at his quadrant, and handling, one after the other, its numerous cabalistical contrivances, he pondered again, and muttered: “Foolish toy! babies’ plaything of haughty Admirals, and Commodores, and Captains; the world brags of thee, of thy cunning and might; but what after all canst thou do, but tell the poor, pitiful point, where thou thyself happenest to be on this wide planet, and the hand that holds thee: no! not one jot more! Thou canst not tell where one drop of water or one grain of sand will be to-morrow noon; and yet with thy impotence thou insultest the sun! Science!...

The Road of Rejecting Your Instruments
The tendency to destroy or abandon tools that show us realities we don't want to face, mistaking the messenger for the message.
Why This Matters
Connect literature to life
This chapter teaches how to identify when someone starts destroying or ignoring the very tools that show them where they actually are.
Practice This Today
This week, notice when someone dismisses bad news by attacking the source—whether it's a scale, a bank statement, or performance review—rather than addressing what it reveals.
Now let's explore the literary elements.
Terms to Know
Quadrant
A navigational tool sailors used to measure the sun's angle and figure out their latitude—basically their north-south position on Earth. Before GPS, this was how ships knew where they were in the middle of the ocean.
Modern Usage:
Like using your phone's GPS to navigate—except imagine smashing your phone and deciding to drive cross-country using only your gut instinct.
Dead reckoning
Navigation by estimating your position based on speed, time, and direction from your last known location—no stars or sun to guide you. It's basically educated guessing that gets less accurate the longer you do it.
Modern Usage:
Like trying to find your way through a new city after your phone dies—you remember you turned left twice and walked for ten minutes, but good luck finding your hotel.
Celestial navigation
Using the sun, stars, and planets to figure out where you are. For centuries, this connected sailors to the heavens and, symbolically, to God's order. Rejecting it means rejecting that divine guidance.
Modern Usage:
We still look to higher powers for guidance—whether that's God, the universe, or expert advice—and rejecting all of it is seen as dangerously arrogant.
Log-line
A rope with knots at regular intervals, thrown overboard to measure a ship's speed. Combined with a compass, it's the most basic way to track where you're going—but errors compound fast.
Modern Usage:
Like tracking your steps with a basic pedometer instead of GPS—it'll give you distance, but won't tell you if you're walking in circles.
Noon observation
The daily ritual where the captain uses the sun at its highest point to determine the ship's position. It's both practical navigation and a moment of connection with the natural order of things.
Modern Usage:
Like checking in with your boss or family every day—it keeps you oriented and connected, and refusing to do it signals you're going rogue.
The white whale as symbol
Moby Dick represents whatever has wounded us that we can't let go of—the thing that hurt us that becomes our obsession. For Ahab, it's literal; for readers, it's whatever we're chasing to our own destruction.
Modern Usage:
Everyone has their white whale—that ex who did you wrong, the job that fired you unfairly, the family member who betrayed you—the wound that becomes your whole identity.
Characters in This Chapter
Captain Ahab
protagonist/tragic hero
Destroys his quadrant in a fit of rage, rejecting celestial navigation and declaring he'll guide the ship by will alone. This act shows his complete break from reason and divine order—he's now at war with the universe itself.
Modern Equivalent:
The boss who deletes all the company protocols and says he'll run things his way
Starbuck
voice of reason/moral compass
Watches in horror as Ahab destroys their navigational tool, seeing it as final proof of the captain's madness. He understands this act dooms them all but feels powerless to stop it.
Modern Equivalent:
The only sane manager watching the CEO drive the company off a cliff
The crew
witnesses/victims
Stand frozen as their captain destroys the instrument that could guide them home. They realize they're now completely at the mercy of a madman's obsession, but are too deep in to turn back.
Modern Equivalent:
Employees watching their leader burn bridges with every client while they worry about their paychecks
The sun
symbolic antagonist
Ahab addresses the sun as a 'high and mighty pilot' that mocks him. By rejecting the sun's guidance, he's rejecting God, nature, and the entire cosmic order that created both him and the whale.
Modern Equivalent:
Whatever higher power or system you blame for your problems—the government, the universe, 'the man'
Key Quotes & Analysis
"Curse thee, thou quadrant! No longer will I guide my earthly way by thee!"
Context: Ahab shouts this while destroying the navigational instrument on deck
This is Ahab's declaration of independence from divine guidance and natural law. By cursing and destroying the tool that connects him to the heavens, he's choosing his obsession over safety, reason, and the lives of his crew.
In Today's Words:
Screw this GPS! I don't need some satellite telling me where to go!
"Science! Curse thee, thou vain toy; and cursed be all the things that cast man's eyes aloft to that heaven, whose live vividness but scorches him!"
Context: Ahab's rejection of scientific navigation and heavenly guidance
Ahab rejects both science and spirituality—anything that would lift his eyes from his obsession. The 'scorching' heaven represents the painful truth he refuses to face: that his quest is meaningless in the cosmic order.
In Today's Words:
Science, religion, therapy—it's all BS that distracts you from what really matters: getting even!
"I'll traverse the world by dead reckoning, and not by observation of the heavens!"
Context: Ahab declares he'll navigate without celestial guidance
Dead reckoning becomes a metaphor for living by pure will and hatred rather than wisdom or guidance. Ahab chooses the most primitive, error-prone navigation method because it depends only on his own calculations.
In Today's Words:
I don't need anyone's advice or help—I'll figure it out myself, my way!
"The old man's demented, I tell ye!"
Context: Starbuck's reaction to Ahab destroying the quadrant
Starbuck's blunt assessment cuts through any romantic notions about Ahab's defiance. This isn't heroic rebellion—it's dangerous madness that will kill them all. Sometimes the truth is simple and terrible.
In Today's Words:
The boss has completely lost it—we're all screwed!

Critical Thinking Exercise
Track Your Own Instrument Rejection
List three 'instruments' in your life that tell you truths you sometimes don't want to hear (scale, bank app, screen time tracker, work reviews, etc.). For each one, write down: (1) What truth it tells you, (2) When you're tempted to ignore it, and (3) What happens when you do. Then identify one instrument you've been avoiding and commit to checking it this week.
Consider:
- •Which instruments trigger the strongest urge to 'look away'? Why?
- •What's the difference between taking a healthy break from monitoring and full rejection?
- •How could you make peace with instruments that show uncomfortable truths?
