in order entirely to enjoy the Poetry which I am recommending, it would be necessary to give up much of what is ordinarily enjoyed. But, would my limits have permitted me to point out how this pleasure is produced, I might have removed many obstacles, and assisted my Reader in perceiving that the powers of language are not so limited as he may suppose; and that it is possible that poetry may give other enjoyments, of a purer, more lasting, and more exquisite nature.
Why does the author specifically say poetry requires giving up other enjoyments? Is this a clear opinion or is there some truth in it?
