Jack. … in order to get up to town I have always pretended to have a younger brother of the name of Ernest, who lives in the Albany, and gets into the most dreadful scrapes. That, my dear Algy, is the whole truth pure and simple.

Algernon. The truth is rarely pure and never simple. Modern life would be very tedious if it were either, and modern literature a complete impossibility!

Jack. That wouldn’t be at all a bad thing. Jack’s speech trimmed at the start

The epigram is a reply, not a standalone maxim: it lands on Jack’s stock phrase “the whole truth pure and simple.” Strip the setup away and the joke’s hinge disappears — which is very likely why the line so often gets reassembled into “the pure and simple truth…”

How we verified it

  • The line is Algernon’s, in Act I. Project Gutenberg’s text of the play ↗ prints Jack’s speech ending “That, my dear Algy, is the whole truth pure and simple,” followed immediately by Algernon: “The truth is rarely pure and never simple. Modern life would be very tedious if it were either, and modern literature a complete impossibility!”
  • The same exchange appears in the Wikisource transcription of Act I ↗, and Wikiquote ↗ lists it in its sourced section for The Importance of Being Earnest (1895), marked Act I.
  • Provenance of the text itself: the play opened at the St James’s Theatre on 14 February 1895 (stated in the front matter of the Gutenberg edition and in Wikipedia’s article on the play ↗), and only reached print in February 1899 from Leonard Smithers.
  • The 1899 first edition is catalogued at the Internet Archive ↗ as “London: L. Smithers, 1899”; Wake Forest’s ZSR Library ↗ records the print run — 1,000 numbered copies, 100 signed oversize copies on handmade paper, twelve on Japanese vellum.
Public domain

The Importance of Being Earnest was first performed in 1895 and first published in 1899, and Wilde died in 1900 — far earlier than any live US copyright term, so the text is public domain. Complete editions circulate freely, including Project Gutenberg’s ↗.

Fact-check

What goes wrong with this one

The author is right; the wording usually isn’t. This is one of the rare famous Wilde lines that really is Wilde — but it travels in a rewritten form, and almost always stripped of the setup that makes it funny.

Oscar Wilde (mis-worded) Misquote

The most-shared form is “The pure and simple truth is rarely pure and never simple.” Wikiquote ↗ flags exactly that: the line is “often quoted as” the ‘pure and simple truth’ version. Goodreads ↗ carries the rewritten wording under Wilde’s name with no source work attached at all.

Wilde speaking in his own person Context

It is dialogue, not an essay aphorism. Algernon Moncrieff throws it back at Jack, who has just called an elaborate cover story “the whole truth pure and simple” — see the exchange in the text of Act I ↗. Quote sites print the punchline and drop the feed line, which is where the joke actually lives.

Wilde wrote it, and the reliable form is short: “The truth is rarely pure and never simple” — Algernon, Act I of The Importance of Being Earnest, first performed 14 February 1895, first published 1899 (full text ↗).

Context

Why it mattered

Jack has just spent a paragraph explaining that he invented a disreputable younger brother so he could escape to town whenever the moral tone of guardianship got too much — and then calls this “the whole truth pure and simple.” Algernon doesn’t argue with the story; he dismantles the phrase. Truth, he says, is rarely pure and never simple, and it is the whole play’s thesis compressed into one sentence.

Timing gave the line an afterlife nobody planned. Earnest opened on 14 February 1895 and played to full houses for six weeks, by the account of Wake Forest’s ZSR Library ↗. Later that same year Wilde himself was in court, convicted of gross indecency and sentenced to two years’ hard labour (Wikipedia ↗) — and a joke about the impossibility of a pure, simple truth stopped reading as only a joke.

Modern life would be very tedious if it were either.

The text behind the line

Wilde first wrote Earnest in four acts; the actor-manager George Alexander asked him to cut it to three before rehearsals, and Wilde combined material from the second and third acts — the largest casualty being a solicitor named Mr Gribsby. The three-act version is the one that opened and the one still performed (Wikipedia ↗).

The play reached print only in February 1899, from Leonard Smithers in London, with sheets printed by the Chiswick Press that January: 1,000 numbered copies, 100 signed and numbered oversize copies on handmade paper, and twelve presentation copies on Japanese vellum (ZSR Library ↗). Wilde, by then in exile, revised the theatre’s working script for the book.

About the author

Who was Oscar Wilde?

Oscar Wilde

1854–1900 · Irish playwright, poet and critic

Oscar Wilde was born in Dublin on 16 October 1854 and died in Paris on 30 November 1900 — an Irish poet, critic and playwright widely regarded as the finest dramatist of the Victorian era. He built whole scenes out of paradox, which is why so many of his lines survive as detached epigrams: the wit is portable even when the plot is not. The Importance of Being Earnest opened in February 1895 at the peak of his fame; later that year he was convicted of gross indecency, was imprisoned from 1895 to 1897, and died in Paris three years after his release.
