We are here in the perception and the expression of the beautiful. There is something unspeakably lovely said in those lines. We are beyond the philosophical notion of metaphor. We are all but beyond what is even expressible by language. Yet it is expressed by language.
Home is the sailor, home from the sea, and the hunter home from the hill.
In those, I think, my friend would say that in a high degree, we have what he would call Metaphor. The perception of the beautiful is intuitive and not precisely conceptual. However, poetry is indubitably done with words, whose business is to manifest concepts. That is, poetry, as with all speech, uses concepts. Yet what it expresses is beauty, and that is not expressed in concepts.
