 Thus for Thomasson, human intentions and concepts are actually constitutive of artifact kinds. Thomasson (2014) also objects to the common assumption that concepts of artifact kinds revolve exclusively around intended function. While it is true that in English we often label artifact kinds in accordance with function—flashlight, bedspread, pincushion, frying pan, and so on—artifacts actually have an array of features that figure in their concepts. These include structural or perceptible features, for example, that are also often reflected in our terms—armchair, tripod, zebra crossing (definitely not a function designation!), fork, and so on. Most importantly for Thomasson, they also include normative features concerned with how that kind of artifact is to be treated or regarded. Although sponges and paper towels can both be used to wipe up spills, it is normal to dispose of the paper towel, but to clean the sponge and reuse it.
