According to the Geach-Chishold objection theory, different kinds of mental states must be connected to different types of behaviours (70). For instance, when an individual is in a mental state of happiness, according to behaviourism, they must be smiling, however according to the Geach-Chishold objection theory, it is not necessary for all minds to think alike, and thus in a mental state of happiness all minds are not always smiling.
