Undoubting Thomas

In one of Dylan Thomas's letters (to 'Miss Hanford Johnson') he says: 'it is part of a poet's job to take a debauched and prostituted word, like the beautiful word "blond" and to smooth away the lines of its dissipation, and to put it on the market again, fresh and virgin.' As you know (what do you mean, you don't know anything of the sort?) I take science fiction to be a poetry. Dylan's instruction works for the tropes of genre, too.
