“This idea of the interface as a material region in which two substances can mix together to produce a completely new hybrid body, can serve as the starting point for rethinking more generally our relationship to the matter around us. If all the bodies we enter into relations with are modified and modify us in turn, then we can no longer delude ourselves that matter is simply a passive object onto which we project our knowledge. But neither can we take refuge in the convenient idea that we can never have any knowledge of that which is not human—that the matter around us is, ultimately, completely alien and unknowable, and that it really has nothing to do with us. Inhabiting the interface affords us the opportunity to redefine our knowledge of matter as a creative and collaborative process in which every material actively participates. Every time we enter into a relationship with a new material, we construct a physical space of mutual interaction which modifies the world around us and opens us to the possibility of modifying ourselves in turn.”
