Dance and music are infectious and non-purposive. Their utility is not clearly manifest.
"When language began to shift hemispheres, and separate itself from music, to become the referential, verbal medium that we now recognise by the term, it aligned itself with a different sort of gesture, that of grasp, which is, by contrast, individualistic and purposive, and became limited to one modality.
