In the speaker's comment he is showing that the poet uses symbolism so that it would make sense for the poet to be using symbolism in the poem they are currently discussing. While the evidence from the "last poem" supports the Jared's opinion and that of the speaker, he is using multiple sources of information to draw his conclusion.
