<span>A theme Wallace Stevens goes back to over and over is that the defining factor of the world we live in isn't really the world itself, but the way we perceive it. We see the world the way we are, not the way it is.
This is the main theme in Anecdote of the Jar, and Thirteen Ways of Looking at a Blackbird; it is probably the main theme of The Blue Guitar. It is an important theme even in poems which have other main messages, including The Emperor of Ice Cream and Sunday Morning. </span>
• Blank verse
Explanation:
Blank verse is a type of verse (frequently written in measured rhyming) that has a standard measurement, yet unrhymed lines. This is the situation in this passage of Paradise Lost, as the lines don't pursue any rhyming example. Blank verse is the most well-known poetic structure in English, and it has been utilized in English verse since the sixteenth century.
