We are starting to do brain-imaging experiments in illiterates, and we find that this region, before it responds to words, has a preference for pictures of objects and faces.

Each instructs; its form and behavior embodies general messages if only we can learn to read them. Making the body work regardless of physical deficit is not a challenge I would wish on anyone, but getting good at being disabled is like discovering an alternative platform.
