Lose ten, twenty, a hundred, it makes very little difference. Our relationship with the universe is of the nature of a language, as Guillermo put it. Language frees us from the tyranny of the senses. Our highly developed voluntary control, a somatic abstraction of sorts, is the flip-side of high level symbolic thought which characterizes human consciousness. We apprehend the world tactually, kinesthetically, through cross-modal transfer, by manipulating internal models of our environment.
Tools are materialized prehensilization.
Ultimately the entire environment is prehensilized by consciousness. It becomes pregnant with incipient tool options, potentiating a vast array of possibilities in the world. A human being can inhabit a machine. The somatic percept, one's kinesthetic self-representation, is extensile. It can flow, proprioceptively, like a phantom nervous system, into the fabric of a machine, be it tool or vehicle.
