Consider this brain puzzle, as presented by philosopher/cognitive scientist/neuroscientist Alva Noë:
"On the traditional conception of the mind, if you want to study experience, you shut your eyes and you introspect. You look inward and reflect on what is going on inside of you, on the inner show. But if experience, if seeing, hearing, thinking, and feeling, isn't something going on inside of you, but is something you do, then you need a different paradigm of what phenomenology would be, that is, of what a reflection on experience itself would be.
"To reflect on experience is not to look inward, it is to pay attention to what you are doing, and to the way in which what you are doing is world and situation and environment involving...To study experience, to think about the nature of experience, is to look at this two-way dynamic exchange between world and the active perceiver."
