I agree with Lowell’s analysis, which is that New England is not the same as the old one he used to know. I agree because in the poem he recites, “Mr. Frost’s is not the kindly New England of Whittier, not the humorous and sensible one of Lowell...where a civilization is decaying to give place to another and very different one.”
Ok he wanted to convey that in deference is worse then hate and anger weisels speaks from he experience of the holocaust by his worth and suffering his consideration
Twain uses irony and sarcasm to characterize the king and duke in such a way that communicates his belief that pretending to be something you are not (for the sake of appearances) is both ridiculous and embarrassing.
