“[Re: playground of the possible:] Conventional teaching and instruction hold always already within themselves the purpose of their object or tool and thus also the limits of its use, value and context. Smith's treatment of tools and things goes beyond those narrow definitions inscribed in use-value, professionalism and a certain identity. It goes beyond those dimensions of an object that ground it within a rational and purposeful world view, and that anchor it in the discourse of the domestic or the professional respectively.”
