metre-making argument

For it is not metres, but a metre-making argument, that makes a poem, — a thought so passionate and alive, that, like the spirit of a plant or an animal, it has an architecture of its own, and adorns nature with a new thing.

—Ralph Waldo Emerson, "The Poet"

duende

Where is the duende? Through the empty archway a wind of the spirit enters, blowing insistently over the heads of the dead, seeking new landscapes and unknown accents.

—Federico Garcia Lorca, "Play and Theory of the Duende," lecture in Buenos Aires, 1933
