I think I have it figured out. I’ve boiled life down to the most elemental action. As I see it now, life is basically an on-going series of moving objects around.
When you build a cob house, you move sand and clay and straw onto a tarp, or into a pit, and continue to move it around with your feet so that it’s mixed. Then you pick it up and move it onto the foundation (which may be a series of stones that you picked up and arranged on top of a drainage trench filled with gravel that you moved into place), and eventually, you get to a place where you might move wood around to form the shape of a roof. Of course the wood will need some work done to it, perhaps some joinery, which means you’ll be moving chunks of material out of the wood itself.
