Even technology makes the mistake of considering tools in isolation: tools exist only in relation to the inteminglings they make possible or that makes them possible. The stirrup entails a new man-horse symbiosis that at the same time entails new weapons and new instruments. Tools are inseperable from symbioses or amalgamations defining a Nature-Society machinic assemblage.
