title: The faux, fake, forged, false, fabricated, and phony: problems for the independence of similarity-based theories of concepts.
abstract: Some things in our environment are not what they seem, and they provide a challenge to theories of concepts that emphasize similarity. Section 1 of my commentary explores a dilemma this situation creates for Machery. Section 2 describes a more general problem for prototype and exemplar theories. Section 3 locates a place for similarity-based concepts, and indicates an alternative to Machery's thesis.
