One of Dylan's poems based on the theme of isolationism. The poison and grapes being used as symbols/metaphors of good and evil. Always skeptical of the good and bad in people of the outside society. Will this isolationist leave or stay that is for the reader to decide. For Dylan leaves his magnificent poem magnificently unresolved.
Keats John as we all know ushered romantic era with myriad lyrics like these. Hats to the poet
I think the poem is about isolation. The white house and the island are literally the speaker's body. The thin sea of flesh is literally, his skin, the bone coast, his skull, with his mind inside. The flesh and skull create a physical barrier from the outside world that represents the figurative barriers between him and society. The poison or grapes represent bad things or good things that are in the outside world. The way the speaker is questioning is really quite immature, he is assuming that the hands and holds contain only poison or grapes, or that society contains only good or evil. However this is not the case, but since the speaker has been living in this mental isolation, he does not realize this. By wondering whether he should let in the stranger or welcome the sailor, the speaker is wondering whether or not he should try to end his isolation.
