Joke Origin: A Clear Conscience Is Usually a Sign of a Bad Memory
Mark Twain? Steven Wright? Senator Sorghum? Philander Chase Johnson? Neal O’Hara? Felix Nieto del Rio? Anonymous?
Question for Quote Investigator: A morally upright individual strives to maintain a clear conscience. Yet, satisfying this goal is not always praiseworthy:
Often a person with a clear conscience merely has a poor memory.
This quip has been credited to famous humorist Mark Twain and popular comedian Steven Wright. I am skeptical of these attributions because I have not seen convincing citations. Would you please help?
Reply from Quote Investigator: The earliest strong match for this joke located by QI appeared in 1902 within “The Evening Star” newspaper of Washington, D.C. The punchline was spoken by the fictitious Senator Sorghum. Boldface added to excerpts by QI:¹
A Delicate Distinction.
“That friend of yours seems to have a clear conscience.”
“No,” answered Senator Sorghum, “not a clear conscience; merely a bad memory — which with some people answers the purpose much better.”
QI hypothesizes that U.S. journalist and humorist Philander Chase Johnson crafted the above instance of the joke. He worked at the “The Evening Star”, and he created the character Senator Sorghum. Also, in 1906 he published a collection of barbs and quips under the title “Senator Sorghum’s Primer of Politics”.² However, Johnson did not place this particular remark into his book.
This jest is difficult to trace because it can be expressed in many ways. Here is an overview listing the key vocabulary employed in different versions over time:
1902 Jul: bad memory
1911 Oct: poor memory
1915 Dec: convenient memory
1917 Apr: short memory
1923 Jan: forgetful
1933 May: dumb
Mark Twain implausibly received credit by 2008. Steven Wright received credit by 1998 several decades after the joke entered circulation.
Below are two precursors and additional selected citations in chronological order.
In 1896 a precursor passage appeared in a short story titled “Sister Sencilla” by Arthur Griffiths published in “The Pall Mall Magazine” of London. An individual described having a clear conscience while admitting an imperfect memory. The statement was not presented as an adage or general principle:³
He implied that I was recovering from a debauch; and although my conscience was clear, so far as my poor memory, my dazed and dumfounded faculties served, I felt all the torments of the awakened drunkard: the parched throat, the swollen tongue, the racking pains across the brow, the leaden heaviness, the utter prostration and helplessness of body and mind.
Another precursor statement appeared in “The Kansas City Star” of Missouri which acknowledged the humor magazine “Puck”. An article titled “Feminettes” contained several statements about women:⁴
Women never play in a game unless there is another game under it.
Ladies fight with pretty words that are full of fists.
Gospel will be a pretty word in a woman’s mouth when women can distinguish between a poor memory and a clear conscience.
In 1902 the remark ascribed to Senator Sorghum appeared in “The Evening Star” of Washington, D.C. as mentioned previously. It was reprinted in other newspapers such as “The Camden Chronicle” of Tennessee which acknowledged the “Washington Star”. This was another name for “The Evening Star”:⁵
“That friend of yours seems to have a clear conscience.”
“No,” answered Senator Sorghum, “not a clear conscience; merely a bad memory — which with some people answers the purpose much better.” — Washington Star.
In 1911 William Jay Schieffelin, retiring President of the National Wholesale Druggists’ Association, addressed the annual convention and presented a version using “poor memory” which he attributed to an old Black philosopher:⁶
“A man often thinks he has a clear conscience, but what he has is nothing but a poor memory.”
In 1915 “The Topeka State Journal” of Kansas printed a set of miscellaneous statements under the title “Journal Entries” including a version of the quip with the phrase “convenient memory”:⁷
The man with a clear conscience must have a convenient memory.
In 1917 the widely reprinted column “Bits Of Byplay” by Luke McLuke published the following version:⁸
Our Daily Special.
A Lot Of People Mistake A Short Memory For A Clear Conscience.
In 1922 Thomas L. Masson published “Our American Humorists” which included a chapter about Johnson:⁹
PHILANDER CHASE JOHNSON, who for more than thirty years past has contributed verse, dialogue, editorial paragraphs, and dramatic criticism to the Washington (D.C.) Star, was born in Wheeling, W. Va. . . .
Philander Johnson established a connection with the Washington Star, and developed the characters “Senator Sorghum,” “Farmer Corntossel,” “Uncle Eben,” “Mr. and Mrs. Torkins” and a number of others that have long been prominently identified with current newspaper humor.
In 1923 “The Evening Star” of Washington, D.C. printed another version attributed to Johnson’s character Uncle Eben:¹⁰
“A man is liable,” said Uncle Eben, “to think he has a clear conscience, when he’s only forgetful.”
In 1933 “The Birmingham News” of Alabama printed the following filler item using “dumb”:¹¹
Yet many a person thinks he has a clear conscience when he just has a dumb one.
In 1939 “The Reader’s Digest” printed this item:¹²
Sometimes a man with a clear conscience only has a poor memory.
— A country editor, quoted by Neal O’Hara
Also, in 1939 columnist by Frederick C. Russell of “The Sunday Star” in Washington, D.C. aimed the barb at automobile drivers:¹³
Many a driver who thinks he has a clear conscience merely has a very bad memory.
In 1947 “The Reader’s Digest” attributed the remark to a diplomat:¹⁴
All too often a clear conscience is merely the result of a bad memory.
— Proverb quoted by Nieto Del Rio, Chilean delegate to U.N.
The important reference work “The Dictionary of Modern Proverbs” contained an entry on this topic with the following interesting citation:¹⁵
1953 Joseph Nuttin, Psychoanalysis and Personality, translated from the German (of 1949) by George Lamb (New York: Sheed & Ward) 69:
“Perhaps the saying ‘All too often a clear conscience is merely the result of a bad memory’ is applicable to the father of the [Freudian] theory that absent-mindedness comes from repression?”
In 1998 a message titled “Steven Wright says: (HUMOR)” appeared in the Usenet newsgroup alt.med.fibromyalgia. Wright received dubious credit for numerous statements including this one:¹⁶
A clear conscience is usually the sign of a bad memory.
In 2001 a columnist in the “Philadelphia Daily News” of Pennsylvania also credited Wright:¹⁷
“A clear conscience is usually the sign of a bad memory.” — Steven Wright.
In 2008 a webpage on the “Goodreads” website credited Mark Twain:¹⁸
“A clear conscience is the sure sign of a bad memory.”
― Mark Twain
In conclusion, Philander Chase Johnson is currently the leading candidate for creator of this joke based on the 1902 citation. There were precursors in the 19th century, but they were distinct. The attribution to Mark Twain is unsupported, and the joke was circulating before Steven Wright was born.
