This Cartesian instrumentalism I think has vast overlay on our experiences, not only conditioning how the art and skill is learned/practiced, but also how it is experienced, what it means to us, and how we relate to ourselves through it. If our bodies are only instruments that obey or fail us this is a very different world to live in, and likely holds a very different set of capacities or ceiling. But the concept of instrumentation also runs out into the very way that Muay Thai is disseminated (or even appropriated) outside of Thailand. It involves our mechanization of its parts (moves, strikes, techniques) the broken way one might Frankenstein parts together (for instance in MMA), and also the way it goes out across the Internet in "breakdowns", which literally "break" "down" the living experiences, often rationalizing it into constituent components and "reasons". The instrumentation of our own bodies, experiencing our bodies as tools or mechanized actions holds its parallel in the commercialization of the art, and a pedagogy of mechanization as well. It all seems to flow from a Cartesian World, one ultimately balanced on the knife-edge of a mythologization of "freedom of choice".
