It is a damn poor mind that can think of only one way to spell a word.

The line is usually invoked to defend nonstandard spelling and to mock pedantry: it suggests that linguistic flexibility is a sign of intelligence, while insisting on a single “correct” spelling is narrow-minded. In popular retellings it also functions as a wry, self-protective joke—turning a potential embarrassment (misspelling) into a claim of mental agility. As a piece of folk wisdom, it reflects an older, more fluid period in English orthography, before mass schooling and standardized dictionaries fully fixed spelling norms. However, because the attribution is shaky, the quote’s significance today is largely cultural: it illustrates how famous figures are used to legitimize attitudes about education, class, and “correctness.”
