It was not right of Coleridge in fact it was wrong
(But often we all do wrong)
As the truth is I think he was already stuck
With Kubla Khan.
He was weeping and wailing: I am finished, finished,
I shall never write another word of it,
When along comes the Person from Porlock
And takes the blame for it.
Coleridge’s Person from Porlock had a good few outings in the mid-twentieth-century.
“…Lady Brandon treats her guests exactly as an auctioneer treats his goods. She either explains them entirely away, or tells one everything about them except what one wants to know.”
“Poor Lady Brandon! You are hard on her, Harry!” said Hallward listlessly. (The Picture of Dorian Gray)
What discussion of aphorism would be complete without Wilde?
