“Why should I not wander over the pastures in search of the wind?” (Gilgamesh lamenting the passing of Enkidu from ‘The Epic of Gilgamesh’)

Who needs rain when the wind is blowing so hard you can taste salt spray within a block of the sea? Pampas grass thrashes, pigeons huddle and runners do a 3-minute mile with ease (as long as they are travelling in the right direction). How do you define something you can’t see, but can feel all around you, something so solid it can knock you off your feet and mould the shapes of trees with its fingers? You can only see what it does, not what it is.

So many questions.
