In a letter (to Goethe I think) Schiller writes of a “poetic mood”. I think I know what he means, I believe I am familiar with it myself. It is a mood of receptivity to nature in which one’s thoughts seem as vivid as nature itself. But it is strange that Schiller did not produce anything better (or so it seems to me) and so I am not entirely convinced that what I produce in such a mood is really worth anything.
