If Pope was unjust to Addison the man, he at least made amends to Addison the moralist. The second passage that may have had an independent existence before the 'Epistle' was conceived is the portrait of Bufo, ll. 229-247. There is reason to believe that this attack was first aimed at Bubb Doddington, a courtier of Hervey's class, though hardly of so finished a type, to whom Pope alludes as Bubo in l. 278. When Pope was working on the 'Epistle', however, he saw an opportunity to vindicate his own independence of patronage by a satiric portrait of the great Maecenas of his younger days, Lord Halifax, who had ventured some foolish criticisms on Pope's translation of the 'Iliad', and seems to have expected that the poet should dedicate the great work to him in return for an offer of a pension which he made and Pope declined. There is no reason to believe that Pope cherished any very bitter resentment toward Halifax. On the contrary, in a poem published some years after the 'Epistle' he boasted of his friendship with Halifax, naming him outright, and adding in a note that the noble lord was no less distinguished by his love of letters than his abilities in Parliament. The third passage, a tender reference to his mother's age and weakness, was written at least as early as 1731,--Mrs. Pope died in 1733,--and was incorporated in the 'Epistle' to round it off with a picture of the poet absorbed in his filial duties at the very time that Hervey and Lady Mary were heaping abuse upon him, as a monster devoid of all good qualities. And now having discussed the various insertions in the 'Epistle', let us look for a moment at the poem as a whole, and see what is the nature of Pope's defense of himself and of his reply to his enemies. It is cast in the form of a dialogue between the poet himself and Arbuthnot. Pope begins by complaining of the misfortunes which his reputation as a successful man of letters has brought upon him. He is a mark for all the starving scribblers of the town who besiege him for advice, recommendations, and hard cash. Is it not enough to make a man write 'Dunciads?' Arbuthnot warns him against the danger of making foes (ll. 101- 104), but Pope replies that his flatterers are even more intolerable than his open enemies. And with a little outburst of impatience, such as we may well imagine him to have indulged in during his later years, he cries: Why did I write? What sin to me unknown Dipt me in ink, my parents' or my own?
