They talked with their bodies. It wasn't all hands, as I'd thought. Any part of the body in contact with any other was communication, sometimes a very simple and basic sort—think of McLuhan's light bulb as the basic medium of information—perhaps saying no more than “I am here.” But talk was talk, and if conversation evolved to the point where you needed to talk to another with your genitals, it was still a part of the conversation. What I wanted to know was what were they saying? I knew, even at that dim moment of realization, that it was much more than I could grasp. Sure, you're saying. You know about talking to your lover with your body as you make love. That's not such a new idea. Of course it isn't, but think how wonderful that talk is even when you're not primarily tactile-oriented. Can you carry the thought from there, or are you doomed to be an earthworm thinking about sunsets?
