What is this thing called ‘Commonsense Psychology’? The first matter to settle is what the issue is here. By ‘commonsense psychology,’ I mean primarily the systems of describing, explaining and predicting human thought and action in terms of beliefs, desires, hopes, fears, expectations, intentions and other so-called propositional attitudes. Although commonsense psychology encompasses more than propositional attitudes--e.g., emotions, traits and abilities are also within its purview--belief-desire reasoning forms the core of commonsense psychology. Commonsense psychology is what we use to explain (...) intentional action as ordinarily described--e.g., Jack went to the store because he wanted some ice cream. Commonsense psychology also is used to explain mental states--e.g., Jill feared that she would be late because she thought that the meeting began at 4:00. Commonsense psychology is the province of everyone; we all use it all the time. (shrink)
