Dickens wrote the line in chapter 12 of Dombey and Son (serialised 1846–48), but in the plural and with a parenthesis: “Ideas, like ghosts (according to the common notion of ghosts), must be spoken to a little before they will explain themselves.” The tidy singular version quoted today is first recorded in a Victorian quotation compilation of 1862 and has circulated ever since.

Popular wording
First recorded in the singular in Henry Southgate’s Many Thoughts of Many Minds, 1862
Unless young Toots had some idea on the subject, to the expression of which he was wholly unequal. Ideas, like ghosts (according to the common notion of ghosts), must be spoken to a little before they will explain themselves; and Toots had long left off asking any questions of his own mind.
Chapter 12
Dickens’s wording, verbatim from the 1848 text. The version that circulates today drops the plural, drops the parenthesis, and drops Toots — without whom the sentence is no longer a joke.
The sentence is in Dickens: chapter 12 of Dombey and Son (1848) at Wikisource ↗ reads “Ideas, like ghosts (according to the common notion of ghosts), must be spoken to a little before they will explain themselves” — plural, in a paragraph about Mr Toots.
Quote Investigator ↗ credits Dickens with the figure of speech and dates the altered singular version to Henry Southgate’s 1862 compilation, tracking its reappearance in 1867, 1872 and 1916 reference works.
Publication dates confirmed against the novel’s publication history ↗: monthly parts from 1 October 1846 to 1 April 1848, one volume from Bradbury & Evans on 12 April 1848.
✓Public domain
Dombey and Son was published in London between October 1846 and April 1848, and Henry Southgate’s Many Thoughts of Many Minds in 1862 — both far earlier than 1931, so the original sentence and the altered singular version are alike in the public domain in the United States. Dickens wrote in English, so no translation copyright arises.

Right author, rewritten words
Nobody stole this line from Dickens — but almost nobody quotes it as he wrote it. Two changes separate the popular version from the novel: the plural became singular, and Dickens’s parenthesis vanished.

Goodreads, AZQuotes and their imitators print the sixteen-word singular version with the parenthesis removed and no work named at all ↗ — which is why the line is so often quoted as a free-floating maxim about creativity rather than as a joke about a slow-witted schoolboy.

Context
A line about unexamined ideas, itself never examined
Dickens is not writing an aphorism here — he is making a joke at the expense of Mr Toots, a wealthy, amiable young man at Doctor Blimber’s school whose brain Dickens likens to a leaden casket giving off a mist that never takes shape. Toots feels something about little Paul Dombey that he cannot say, and the narrator explains why: ideas, like ghosts, have to be questioned before they will account for themselves, “and Toots had long left off asking any questions of his own mind.”
Lifted out of that paragraph the sentence became a maxim about creativity, and it has been quoted that way for more than a century and a half — in the singular, with Dickens’s hedging parenthesis quietly removed. The irony is hard to miss: a line about how ideas must be interrogated before they explain themselves has itself gone uninterrogated by nearly everyone who has repeated it.
Ideas, like ghosts, have to be spoken to — and so, it turns out, do quotations.
How the wording changed
Dickens, 1846–48. “Ideas, like ghosts (according to the common notion of ghosts), must be spoken to a little before they will explain themselves” — plural subject, plural verb, parenthesis intact.
Southgate, 1862. The earliest instance of the singular form located by Quote Investigator ↗ — filed under the topic heading “Evoking an Idea” in a quotation treasury that still credits Dickens.
Today. The parenthesis has gone too, leaving the sixteen-word version that circulates on quote sites with no work named at all.

Charles Dickens (7 February 1812 – 9 June 1870) was an English writer and journalist, and the defining novelist of the Victorian era. Dombey and Son — published in nineteen monthly parts from October 1846 to April 1848 and in one volume that April — came at the height of his powers, and its portrait of the wealthy, emotionally frozen Mr Dombey is one of his sharpest studies of pride. The ghost simile belongs to a comic aside about Mr Toots, a good-natured young man whose head Dickens describes as a leaden casket that never quite gives up its contents.
