Commentary on Meditations: B1.10

10. From Alexander the grammarian: not to leap on mistakes, or captiously interrupt when anyone makes an error of vocabulary, syntax, or pronunciation, but neatly to introduce the correct form of that particular expression by way of answer, confirmation, or discussion of the matter itself rather than its phrasing - or by some other such felicitous prompting.

this passage is all one thought; and it is about giving feedback - or coaching.

in a word, this passage is about tact.

definition of tact is: sensitivity in dealing with others or with difficult issues.

if someone makes a mistake (in this case a grammatical mistake), don't be that "know-it-all" and immediately jump all over the person.

think of Hermione and how she somewhat arrogantly corrects Ron: https://www.youtube.com/watch?v=fx2zLgdkJpk
