Abstract

According to the dual nature thesis, technical artifacts have a dual nature: they are material objects that have a material base, but also functions that depend on their intentional history, in particular their intended and actual use. In an influential paper, Houkes and Meijers argue that the dual nature thesis does not square well with the seemingly plausible idea that the function of a technological artifact supervenes on its material base. They correctly point out that many versions of the supervenience thesis are unable to account for the following two-way underdetermination condition: “an artefact type, as a functional type, is multiply realizable in material structures or systems, while a given material basis can realize a variety of functions” (Houkes and Meijers 2006, 120). In this paper, I articulate a supervenience thesis that is compatible with the two-way underdetermination condition.
