Mark Twain? Steven Wright? Senator Sorghum? Philander Chase Johnson? Neal O’Hara? Felix Nieto del Rio? Anonymous?
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: 1902 July 21, The Evening Star, Shooting Stars: A Delicate Distinction, Quote Page 4, Column 3, Washington, D.C. (Chronicling America)
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”.1906, Senator Sorghum’s Primer of Politics: Or, Helpful Hints on the Science of Not Getting the Worst of it by Philander Chase Johnson, (The phrase “clear conscience” is not present in … Continue reading 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.
