To what extent is an immediate relationship with our non-human surroundings a language? — Joshs

Language is communication. Without the narrative the video would not have communicated much to me. With the narrative, what was communicated was something profoundly different! But I think what you are getting at is that a relationship entails communication, so it is a language. Which would mean the way we live our lives is a language. Yes I suppose that is true. The way an artist paints in art has long been understood as a language; their style is their language, regardless of their intention, regardless of what they achieve.
