The 'whether?' question: does perception provide us with reasons for belief about the external world? The 'how?' question: how does perception provide us with reasons for belief about the external world? The 'when?' question: when does perception provide us with reasons for belief about the external world? The 'what?' question: what are the reasons that perception provides us with for belief about the external world
