In "Forgetfulness", by Billy Collins, the possible theme of the poem is<em> D. Retiring, packing a bag, and floating down a river are similar to losing one's memory</em>. First, Collins writes that we first forget the author of a novel and then we completely forget of its existence at all. Lost memories are compared to someone retiring to a fishing place without phones, so we cannot reach them. There is a personification when he writes that the memory of the quadratic equation "pack its bag". He then writes about floating down the Lehte river, it is a Greek mythological river and if you floated down its waters you forgot what you knew.
The use of the refrain does not contribute to the meaning of the poem.
In this case, the purpose of the authors with this passage is to emphasize the rivalry between Jack and Ralph, this is shown as the author explains the differences between Jack and Ralph ideas about survival. This passage shows Ralph would us commonsense, logic and civilized principles to survive through "the world of longing" (what is real) and the "baffled common sense". On the other hand, Jack would use more barbaric strategies such as "hunting" or "fierce exhilaration".
These opposite points of view are confronted during the story as Jack becomes the antagonist and a barbaric leader. While Ralph attempts to be the civilized leader of the group.
