After observing a play, Samuel Johnson was spending some time with two of the actors in a tavern and remarked that players had “a kind of rant, which which they run on, without any regard either to accent or emphasis.” In the ensuing debate Johnson challenged them to repeat the ninth commandment with proper emphasis and to his delight, both failed.
Dr. Taylor, another chap present, reported it to Boswell who did not agree that Johnson can have argued that the emphasis should be on not and false witnesses because he puts in a footnote that the emphasis should be on shall and not and false witnesses should only be distinctly enunciated.
Johnson apparently was able to convince these actors upon reasoning they must have found sound that there was an absolutely proper way to say the ninth commandment, and by implication anything. I heartily wish more of that conversation had survived.
