Words act in the world. They do work. Never merely word-thoughts nor despairingly inadequate translations of wordless thoughts.
Words are infrastructure of social body that stands outside us, skeleton calcified through collective usage. To speak words is to exercise ligaments & tendons that exist outside our intentions.
Posture is habit. Fallen into without meaning to. Repetitive strain injuries are postural habits as injury. Words, always, are muscle twitches of a body that is not ours alone.
