Eliminating the “concept” concept [PDF]

Behavioral and Brain Sciences, 2010
AbstractMachery suggests that the concept of “concept” is too heterogeneous to serve as a “natural kind” for scientific explanation, so cognitive science should do without concepts. I second the suggestion and propose substituting, in place of concepts, inborn and acquired sensorimotor category-detectors and category-names combined into propositions ...
