Hohne Horst notes that the poet's utopia "is the picture of a community of lovers after the model of Plato's dialogues. In unison with enlivening nature, the poet endeavors to enchant her: they would live on a lonely island cultivating their ideal goals." Horst then quotes lines 560-72:
Our breath shall intermix, our bosoms bound,
And our veins beat together; and our lips
With other eloquence than words, eclipse
The soul that burns between them, and the wells
Which boil under our being’s inmost cells,
The fountains of our deepest life, shall be
Confused in passion’s golden purity,
As mountain-springs under the morning Sun.
We shall become the same, we shall be one
Sprit within two frames, oh! wherefore two?
Why "two frames"? For Shelley, it seems as if Platonism allows for subjectivity to have form, and part of him wants to annihilate form, to allow his sympathy to completely transcend the boundaries of his own sensibility. How can it be two frames if "our breath shall intermix, our bosoms bound" ? The answer must be this: he is conscious of the dream, but he cannot forget the irrationality of it. Rationally, he realizes that such an intermixture is impossible for his imagination and his language to fathom; but, he continually attempts to sustain this perfect picture.
