Step-by-step explanation:
The phrase "Is good would never be a man of letter" is grammatically incorrect and does not clearly indicate whether it is in the first person or third person. However, if the phrase is intended to be corrected to "A good man would never be a man of letters," it is in the third person. In this corrected version, it refers to a hypothetical good man who would not pursue a scholarly or literary career (a "man of letters").
