1Some say the world will end in fire,
2Some say in ice.
3From what I’ve tasted of desire

9And would suffice.
The poem in 60 seconds

The poem has nine lines and about fifty words, and it takes on the end of the world. Its speaker talks about the apocalypse in the tone of someone settling a dinner-table argument. Under the casual voice is a dark idea: the feelings that could destroy everything are ones the speaker already knows from the inside.

The speaker opens by reporting a debate. Some people expect the world to burn, and others expect it to freeze. Judging from personal experience of desire, the speaker sides with fire. Then the speaker imagines a second ending. If the world could be destroyed a second time, the speaker says, experience of hate is enough to show that ice would be just as destructive, and would do the job. The poem takes two old images of the end of the world and quietly turns them into images of human feeling. Fire goes with desire, a hot and consuming passion. Ice goes with hate, which is cold and hardening. The speaker never claims to know which ending will come and offers only a personal opinion on each. The poem closes on a dry understatement: ice “would suffice.”

Speaker & situation

SpeakerAn unnamed “I” who speaks casually and with some wit. The speaker’s authority comes not from science or scripture but from personal experience of desire and hate.
Addressed toNo one in particular. The poem sounds like one voice joining a conversation that “Some” people are already having.
OccasionAn old question, how the world will end. The astronomer Harlow Shapley later recalled that Frost once asked him that question, and some readers link the conversation to the poem; the poem itself names no source.
ToneWry, understated and darkly ironic. The speaker treats the end of the world as a matter of mild opinion, which makes the claim underneath it more unsettling.

Form & sound

FormLyric poem; nine lines in a single stanza, built on only three rhyme sounds.
MeterMostly iambic tetrameter, eight syllables and four beats to the line, as in line 1. Lines 2, 8 and 9 are cut to four syllables and two beats, so the poem keeps pulling up short.
Rhyme schemeABAABCBCB. Fire and desire rhyme (lines 1, 3 and 4), ice rhymes with twice and suffice (lines 2, 5, 7 and 9), and hate rhymes with great (lines 6 and 8). The ice sound returns most often and has the last word.
SoundThe s sounds of “Some say” (lines 1 and 2) return in “suffice” at the very end. The short final lines slow the poem and give its closing words a clipped, final ring.
StructureThree sentences. The first (lines 1 and 2) sets out the debate, and the second (lines 3 and 4) chooses fire. The third (lines 5 to 9) imagines a second ending and makes the case for ice, finishing in the two shortest lines.

Line by line what each part says and does

  1. 1

    Lines 1–2

    Two predictions

    The speaker reports an old disagreement: some expect the world to end by burning, others by freezing.

    How it worksThe balanced, almost offhand opening makes the end of the world sound like a topic of casual debate. The second line is half as long as the first, a pattern the poem returns to at its close.

  2. 2

    Lines 3–4

    The case for fire

    Based on what the speaker has “tasted” of desire, the speaker agrees with those who say fire.

    How it worksHere the poem turns from the world to the self. Fire becomes a figure for desire, and the speaker’s evidence is private experience, not prophecy or science.

  3. 3

    Lines 5–9

    The case for ice

    If the world could be destroyed a second time, the speaker says, knowing hate as well as the speaker does is enough to show that ice would do the job just as well.

    How it worksThe second half is longer than the first and ends in two clipped lines. Calling ice “great” and saying it “would suffice” describes total destruction in the mildest possible words.

The turn

Lines 5

Lines 1 to 4 settle the question in favor of fire. Line 5 begins with “But” and imagines the world perishing a second time, which opens the case for ice. The shift moves the poem from desire to hate, and from a quick opinion to a slower, colder conclusion.

Literary devices with line numbers

Symbolism

Fire and ice are the two possible ends of the world in lines 1 and 2, but lines 3 and 6 tie them to human feeling: fire to desire and ice to hate. The physical apocalypse becomes a picture of what passion and hatred can do.

Antithesis

Lines 1 and 2 set fire and ice against each other in parallel phrases beginning “Some say.” The whole poem is built on that opposition of hot and cold.

Understatement

In lines 8 and 9 the speaker says only that ice is “also great” and “would suffice” for destroying the world. The flat, modest words for a total catastrophe create the poem’s dark humor.

Shift in scale

The speaker judges the fate of the whole world by personal feelings: what the speaker has “tasted” of desire (line 3) and knows “enough of” hate (line 6). The jump from the private to the global suggests that the forces that could end the world are already inside ordinary people.

Line length

Lines 2, 8 and 9 are only four syllables long, half the length of the others. The short lines at the close make the ending sound curt and final, as if nothing more needs saying.

Themes in Fire and Ice

Desire as destructionThe power of hateThe end of the world

Desire as destruction

The speaker links fire with desire (lines 3 and 4). Passion, greed or appetite can burn through everything, and the speaker has felt enough of it to believe it.

The power of hate

Ice stands for hate (line 6), slower and colder than fire but, the speaker says, just as able to destroy. The poem suggests that cold feeling is as dangerous as hot feeling.

The end of the world

The poem takes up an old question about how the world will end. Its answer is less about physics or scripture than about human nature.

Images and symbols

Fire

One of the two traditional ends of the world. In the poem it stands for desire, a hot, fast, consuming force.

Ice

The other end of the world. In the poem it stands for hate, cold, hardening and slow, and it gets the last rhyme.

Tensions

Fire vs. ice. The poem sets two kinds of destruction against each other, passion and hatred. It never chooses between them for good: fire wins the first round, but ice is judged equal to the task.

The ending

How Fire and Ice ends, explained

The poem ends in its second, colder half. After choosing fire, the speaker imagines the world having to perish twice and concludes that ice, which stands for hate, would be “great” for destruction too and “would suffice” (lines 8 and 9). Those last two lines are the shortest in the poem, and they describe total destruction in the most modest words available. That understatement is the key to the ending. Many readers hear dry humor, a speaker shrugging at the apocalypse. Others hear a harder claim underneath: that the cold, slow force of hatred is as deadly as the quick burn of desire, and perhaps more frightening because it is quieter. The speaker’s authority adds to the unease. Everything rests on what the speaker has tasted of desire and knows of hate, so the forces that could end the world are ones an ordinary person already carries. Some critics connect the poem with Dante’s Inferno, where the lowest circle of Hell is a frozen lake that holds traitors, while sinners of passion are punished in higher circles. On that reading, ice would be the worse fate. The poem never mentions Dante, and it leaves the two endings in balance.

“Some say the world will end in fire, / Some say in ice.”
Lines 1–2. The poem opens as a report of other people’s opinions, in a casual tone that makes the end of the world sound like small talk.
“From what I’ve tasted of desire”
Line 3. The turn inward. The speaker’s evidence is personal, and “tasted” makes desire something known through the senses.
“And would suffice.”
Line 9. The final understatement. Destroying the world with ice would simply be enough, and the poem ends on the cold rhyme.

Common misreadings

MythThe poem is a scientific prediction about how the world will end.

ActuallyThe speaker’s evidence is personal, not scientific: what the speaker has tasted of desire (line 3) and knows of hate (line 6). Fire and ice work as images of human feeling.

MythThe speaker says ice would be worse than fire.

ActuallyThe speaker sides with fire (line 4) and says only that ice is “also great” and would suffice (lines 8 and 9). The poem treats them as equal; the idea that ice is worse is a reading, not a statement.

MythThe speaker claims to know how the world will end.

ActuallyThe poem is full of hedges: “Some say,” “I hold with,” “I think.” The speaker offers an opinion, and the poem’s calm tone depends on that modesty.

Answer

Explain it like I’m 12

People have long argued about whether the world will end in fire or in ice. The speaker of this poem says that, from feeling strong wants and desires, fire seems likely. But the speaker has also felt hate, and hate is cold like ice. So ice could destroy the world just as well. The poem is really saying that strong feelings like desire and hate can be very dangerous.

Compare & connect

The Second Coming

W. B. Yeats

Published in 1920, the same year as Frost’s poem, it also imagines the world coming apart. Yeats uses prophecy and a terrifying vision, while Frost uses a quiet, wry voice.

Ozymandias

Percy Bysshe Shelley

A short poem about destruction and what human passions come to in the end. Both poems use a calm, compact form to make a large claim.

Nothing Gold Can Stay

Robert Frost

Another very short Frost poem collected in New Hampshire, which also moves from a simple statement to a rule about endings and loss.
