 The function acquisition story proposes that during development, an organism is trained to discriminate real flesh and blood dogs from questions, foxes, stuffed dogs, paper mâché dogs under conditions of good lighting, without occlusions, or distractions. A teacher ensures that training proceeds according to plan. Once “X” has acquired the function to respond to dogs, the training is over. Thereafter, any instances in which “X” is triggered by foxes, stuffed dogs, paper mâché dogs, LSD, microelectrodes, etc., are false tokenings and figure into false beliefs.
