I tend to think of a gorge as a place – a stone valley, really. And so it is funny to imagine a place like that within a person. But in fact, the place, the natural formation, is named for the body. That is, gorge is from the French for the throat, and the sense of gorge as a passage, a narrow passage, is actually evoking the body, the narrow passage of the throat.
And, of course, the body is how any human being experiences and understands the world – so it makes so much sense that the natural world is named for us rather than the other way round.
