Who really said it

We are what we pretend to be, so we must be careful about what we pretend to be

Written by Kurt Vonnegut 1922–2007 · American novelist and essayist
Verified In copyright

Vonnegut wrote it himself. It is the moral he states outright in the introduction he added to the 1966 edition of Mother Night — his 1962 novel about an American playwright in Berlin who broadcasts Nazi propaganda while passing coded intelligence to the Allies. Wikiquote files the line in its sourced section for the novel, and Wikipedia’s article on the posthumous collection We Are What We Pretend To Be, which is named after this sentence, quotes the same wording from the same introduction.

We quote the sentence and nothing around it. Mother Night is still in copyright, so we have not reproduced the rest of Vonnegut’s introduction.

Wikiquote — Kurt Vonnegut, Mother Night

How we verified this

  • Wikiquote lists the line in its sourced section for Mother Night, locating it in the Introduction (1966) and recording the variant that circulates in its place Wikiquote — Kurt Vonnegut ↗.
  • Independently, Wikipedia’s article on the 2013 posthumous collection We Are What We Pretend To Be: The First and Last Works states that its title comes from the preface of the 1966 edition of Mother Night, and quotes this exact wording Wikipedia — We Are What We Pretend To Be ↗.
  • The dates behind that are both documented: Mother Night was first published in February 1962 by Fawcett/Gold Medal, and the introduction is dated four years later Wikipedia — Mother Night ↗.
  • What we could not do is read the printed introduction ourselves. The book is in copyright and the Internet Archive’s scans are lending-restricted Mother Night at the Internet Archive ↗, so this rests on two separate Wikimedia projects agreeing on the wording, its placement and its date — not on our own sight of the page.
In copyright

Mother Night was first published in 1962 and this sentence comes from an introduction added in 1966, so both the novel and the introduction sit well inside US copyright. Quoting the single sentence with attribution is ordinary critical use; reproducing the surrounding passage is not. This is not legal advice.

Rights status is our research, not legal advice — and copyright varies by country and edition. For commercial or published use, confirm with the rightsholder. See terms.

Fact-check

Right author, drifting words

Nobody else is credited with this line — the problem is the wording. It is repeated in several forms, and the one Vonnegut actually wrote is not always the one that travels.

Same author, rearranged wording drift

Wikiquote records the line as “sometimes misquoted” in the inverted form ‘Be careful what you pretend to be because you are what you pretend to be’ Wikiquote ↗. It carries the same idea and is not Vonnegut’s sentence.

Kurt Vonnegut sourced

The form printed in the 1966 introduction is ‘We are what we pretend to be, so we must be careful about what we pretend to be’ — the wording both Wikiquote and Wikipedia reproduce Wikipedia ↗.

The attribution is right and the sentence is real; if you are quoting it, quote the version Vonnegut printed Wikiquote — Kurt Vonnegut ↗.

Context

Why it mattered

Mother Night is narrated by Howard W. Campbell Jr., an American playwright who spends the war in Berlin as the English-language voice of Nazi propaganda. The idiosyncrasies of his broadcasts — the deliberate pauses, the coughing — are coded intelligence he is passing to the American Office of Strategic Services, and he never learns what any of it says.

So the moral is not a slogan about self-improvement. Campbell’s excuse is that underneath the performance he was on the right side; the book’s answer is that the performance was the part that reached people. Vonnegut put that in the introduction rather than the novel, four years after the novel came out.

The pretence was the part that reached people.

Where the book came from

Vonnegut told Charlie Rose in 1996 that he was paid $3,000 for the novel, at a time when he “needed the money”.

He said the idea came from a cocktail party on Cape Cod, where he met a former wartime spymaster who complained that spy films made no sense: “Any time you have an agent inside an enemy country, this is a very sick person you are dealing with.”

The starting point for Campbell was the British broadcaster Lord Haw-Haw, hanged for treason after the war. Vonnegut’s move was to ask what would happen if an American did the same thing.

The line later gave its title to We Are What We Pretend To Be: The First and Last Works, a collection of two previously unpublished novellas issued after his death.

About Kurt Vonnegut

Kurt Vonnegut

1922–2007 · American novelist and essayist

Kurt Vonnegut survived the firebombing of Dresden as an American prisoner of war and spent the next fifty years writing books that refuse to separate comedy from atrocity. Mother Night (1962) was his third novel and the one he gave an explicit moral, in an introduction added four years after publication.
