Running seems a useful metaphor for many things I believe about the nature of the physical world and our relationship to it.
First existence is wrapped up with movement, of planets, of air, of atoms etc. With this movement also comes the exchange of molecules; for example, from our skin and when we breathe. This exchange interweaves us with our surroundings, our element.
Every simple or complex collection of molecules shares and is affected by movement through time. The phrase "slipping glimpser ", coined from painter William de Kooning, comes to mind. As observers slipping and glimpsing, seeing as we move and moving as we see, sliding through time and space as everything else slips and slides past and through our semi-permeable membranes and minds.
