 Introspection is generally regarded as a process by means of which we learn about our own currently ongoing, or very recently past, mental states or processes. Not all such processes are introspective, however: Few would say that you have introspected if you learn that you’re angry by seeing your facial expression in the mirror. However, it’s unclear and contentious exactly what more is required for a process to qualify as introspective. A relatively restrictive account of introspection might require introspection to involve attention to and direct detection of one’s ongoing mental states; but many philosophers think attention to or direct detection of mental states is impossible or at least not present in many paradigmatic instances of introspection.
