How Fullmetal Alchemist's Equivalent Exchange Narration Changes

The 2003 anime and Brotherhood both have a narration on the law of Equivalent Exchange, worded differently, and both finales amend it. A comparison from episode-labeled transcriptions, and why the VIZ manga is not quoted.

Spoilers throughout. This page assumes you have finished the series.

In Wikiquote's transcription, the 2003 Fullmetal Alchemist anime introduces episodes 2 to 41 with Alphonse stating "alchemy's first law of Equivalent Exchange" and admitting the brothers once believed it was the world's only truth; Brotherhood's narration, transcribed under its fourth episode, has an unnamed narrator state the same law and then the taboo on human transmutation. Both finales come back to the law and amend it. The wording quoted below comes from Wikiquote's episode-labeled English transcriptions, which do not say whether they follow a subtitle or dub track; VIZ's English manga is described but not quoted, for reasons given at the end.

The 2003 series: a law stated in hindsight

The 2003 anime ran for 51 episodes, from October 4, 2003 to October 2, 2004, according to Anime News Network's encyclopedia. Wikiquote records Alphonse's introduction for episodes 2 to 41, beginning "Humankind cannot gain anything without first giving something in return," and ending "In those days, we really believed that to be the world's one, and only truth."

The last sentence is the important one. "In those days" puts the narrator after the story, looking back; one reading is that it tells the audience from the second episode that the law is going to fail somewhere. Wikiquote also records a different introduction for episodes 43 to 51, credited to Edward, about the Philosopher's Stone letting its holder "gain without sacrifice", and adds a note that the line is Alphonse's in the original and given to Edward only in the dub.

Brotherhood: a rule and a taboo

Brotherhood ran for 64 episodes, from April 5, 2009 to July 4, 2010, per the same encyclopedia. Wikiquote transcribes its narration under episode 4, "An Alchemist's Anguish", with the speaker labeled only "Narrator". It begins "Alchemy. The science of understanding, deconstructing and reconstructing matter." It goes on to the law (if one wishes to obtain something, "something of equal value must be given") and ends on the taboo: "For what could equal the value of a human soul?" Wikiquote does not say in which other episodes the narration is used, so this page does not claim it opens every episode.

The difference, as we read it, is one of stance. The 2003 version is a confession by a character who has already learned better. The Brotherhood version is a statement of the rules, with no narrator's doubt attached; the doubt is left for the story to supply.

How each finale revisits it

In the 2003 series, Wikiquote's transcription of episode 51, "Laws and Promises (Munich 1921)", has Alphonse repeat the opening almost word for word and then continue past it: "But the world isn't perfect, and the law is incomplete." He goes on to say he no longer thinks of Equivalent Exchange as a law of the world but as "a promise, between my brother and me."

Brotherhood answers its narration in episode 64, "Journey's End". In Wikiquote's transcription, Gracia Hughes asks whether repaying kindness is what alchemists call Equivalent Exchange, and Alphonse replies that taking ten and giving ten back is equivalent, but adding something of yourself returns eleven. Edward then proposes to Winry in the law's own terms, offering half his life for half of hers; Winry calls the idea "nonsense" and offers more. The transcription closes with Edward's final lines, which begin "There’s no such thing as a painless lesson."

So the two series end in different places. The 2003 finale keeps the principle and changes its status, from law to promise. Brotherhood keeps the arithmetic and breaks the balance on purpose: ten in, eleven out. One reading is that the 2003 ending is about faith and Brotherhood's is about generosity; the transcriptions support either.

The manga, and what we could not read

VIZ Media publishes Hiromu Arakawa's manga in English, and this page does not quote it, because we could not read the relevant pages of a VIZ volume from an official source. Wikiquote's manga page records narration at the failed transmutation, in its section headed "The Two Alchemists", about a lesson without pain having no meaning and nothing being gained without sacrifice. That page does not say whose translation it uses, so we do not treat its wording as VIZ's, and we do not quote it here.

The echo is still visible in outline: Brotherhood's closing line about a painless lesson answers that early narration, and the same Wikiquote manga page carries Edward's half-a-life proposal in its section headed "The Journey's End". Which English words VIZ prints for either moment is a question for a reading of the licensed volumes. Whether Edward ever said the popular "a lesson without pain is meaningless" wording is checked separately in did Edward really say "A lesson without pain is meaningless"?
