Johnson said this to Sir Joshua Reynolds; James Boswell recorded it in his ‘Life of Samuel Johnson’ (1791), within the section covering the year 1755. The popular wording matches the primary text verbatim — it is a genuine Johnson remark, not a paraphrase.

Author / recorder
James Boswell (from Johnson’s spoken words)
First published
1791
Spoken to
Sir Joshua Reynolds
The proposition which I have now endeavoured to illustrate was, at a subsequent period of his life, the opinion of Johnson himself. He said to Sir Joshua Reynolds, ‘If a man does not make new acquaintance as he advances through life, he will soon find himself left alone. A man, Sir, should keep his friendship in constant repair.’
Boswell places the remark within his narrative for the year 1755, but notes Johnson made it “at a subsequent period of his life” — so the exact date of the conversation with Reynolds is not fixed.
Quote Investigator has not published a dedicated inquiry, but Wikiquote’s sourced section lists the line as genuine, crediting Boswell’s ‘Life of Johnson.’
We confirmed the exact wording against a scholarly transcription of the 1755 section of Boswell’s text at Jack Lynch’s Rutgers edition, which reads “in constant repair” verbatim.
The remark is Boswell reporting Johnson’s spoken words to Sir Joshua Reynolds — it is not from Johnson’s own essays or letters, and Boswell inserts it to illustrate the value of keeping up acquaintance.
✓Public domain
The line comes from James Boswell’s ‘Life of Samuel Johnson’, first published in 1791 — long before the 1931 cutoff — so both Johnson’s reported words and Boswell’s text are in the public domain in the United States.
Fact-check
A genuine quote — but watch the wording
Unusually for a “Samuel Johnson” quote, this one is real. The confusion here is not who said it but how it is quoted and credited.
✕
Wording variant“in a constant repair” variant
Some references, including Wikiquote, print “in a constant repair.” The scholarly transcription of Boswell’s text reads “in constant repair” without the article, which matches the most common popular form.
✕
Source typeJohnson’s own writing misframed
The line is often quoted as though from an essay or letter Johnson wrote. It is actually his reported speech, recorded by James Boswell — we owe the sentence to Boswell’s biography, not to Johnson’s pen.
✕
Dating“the year 1755” context
Boswell records the remark in his 1755 chapter, so it is sometimes dated to 1755; but Boswell himself says Johnson made it “at a subsequent period of his life,” so the precise date of the conversation is unknown.
✓The quotation is authentic: Johnson said it to Sir Joshua Reynolds, and Boswell preserved it in the Life of Johnson (1791).
Context
Why it endures
Johnson’s point is that friendship is not a possession but a practice. Left untended, even close bonds decay; new acquaintance must be made as life advances, or “a man … will soon find himself left alone.” The metaphor of “repair” casts a friendship as a structure needing continual upkeep — a strikingly modern idea about the work relationships require.
The saying carries extra weight because of who preserved it. Johnson and Boswell’s own friendship, and Johnson’s decades-long bond with the painter Sir Joshua Reynolds to whom the remark was addressed, were themselves models of the kind of maintained affection the line describes.
“A man, Sir, should keep his friendship in constant repair.”

1709–1784 · English author, lexicographer & critic
Samuel Johnson was one of the towering figures of 18th-century English letters — poet, essayist, critic, and compiler of the landmark A Dictionary of the English Language (1755). Renowned for his aphoristic conversation, he is among the most-quoted figures in the language, largely because his friend James Boswell recorded his talk in extraordinary detail. This remark on friendship is one such recorded saying, addressed to the painter Sir Joshua Reynolds.
