No, not the CIA thing where people imagined themselves drawing pictures of enemy infrastructure. It would be a very different world if we could imagine what our friends and loved ones were doing throughout the day…. accurately. Maybe it would even be a better one, though I suspect most of us would consider it a markedly creepier instead. In this case, I’m referring to a lovely article demonstrating that we handle tools as if they really were “extensions of ourselves,” in spite of the face that said tools don’t have any nerves with which to help us sense with them. We can tell how things make contact with inanimate objects we’re holding. How cool and weird is that? As a fencer, it’s common to say “the sword is an extension of your arm.” And that’s more or less accurate. (It would be more accurate, and also more confusing, to say that the sword is an extension of your feet!) Turns out, it’s super cool….but not at all weird. You see, your bones don’t have nerves, either. So all our sensing of what happens with our bones is indirect and “through a mirror darkly.” That’s why descriptions of bones cooperating in traditional cultures frequently fall back on ideas like “chi flow” (e.g., if you’re a Tai Chi player, peng, ji, lu, an). If you’re well-organized, you can feel something moving around and providing support out to your head or hands, but… “what is that darned thing I’m feeling?” And if you’re sore as heck and not sure why you’re sore as heck, figuring out what it is you’re feeling gives you better access to those bones, as well as whatever tools you happen to be holding at the time, and how to use all of them better. It’s a win win. sneaky clever nervous system…!
