One of the interesting things about the history of poetry in the 16th, 17th, and 18th centuries is that people who read liked getting their information in rhyme just as much as in prose. The genre that we would think of as nonfiction often was written in verse in forms like the Georgic when people thought that one of the tasks of poetry was conveying arguments and information in a pleasant way.
Robert HassNot to make too much of a claim for poetry, but this is a question that goes to the moral heart of the business of any art: How do you see the world, and what right do you have to see the world in the way that you do?
Robert HassI think that poets can say, "What we want is for everybody on earth to wake up free from fear and with access to medicine and clean water and education." But I don't think poets have any special insight on how to get there. And the 20th century is a pretty good record of that because so many of the great poets were Stalinists: Vallejo, Neruda, Eluard, Aragon, etc. They wrote their odes to Lenin and Stalin. They glorified some of the most violent and grotesque dictatorships of the 20th century. And a lot of the ones who were not Stalinists were fascists or fascist sympathizers.
