I'll also add that, if we can agree that a tool's external telos is defined by a Organic System (an 'agent' within Complexity, from single cells to ecosystems and organizations), what does that imply about us? Sure, our telos to a degree is internally defined, but we still exist within larger systems, and the behavior of those larger systems can be described by what orients that larger system - without even describing us as individual components just as we can talk to each other at levels higher than the individual cells or proteins that make us up. So think about the ever expanding larger systems we belong to, from intimate partnerships to society and beyond. The very fact that we are subsystems of the Natural World means we inherit some form of orientation from it.
Really. Take a few moments to ponder that - what might be the 'thing' we inherit from the largest all encompassing system that could orient us?
