De Gustibus Non-Est Disputandum
A Latin maxim meaning "In matters of taste, there can be no disputes" — suggesting that personal preferences are subjective and cannot be argued as if one preference is "right" or "wrong".
Origin
A Latin maxim meaning "about tastes, it is not to be disputed," probably of Scholastic origin. One known early use appears in a 1628 legal text, Repetitio legis Imperialem de prohibita feudi alienat. per Fridericum, by Horatius Montanus (Naples). Although sometimes attributed to ancient Roman origins, no earlier attestations have been reliably documented, suggesting it emerged as a proverbial expression in early modern Latin scholarship. The phrase combines gustibus (ablative plural of "taste") with the gerundive disputandum ("to be disputed"), conveying "it is not to be disputed about tastes."
