Looking into one’s own mind, to find what one thinks and feels. The idea that this process is rather like that of perception, only turned inwards, is rejected by most current philosophers of mind. Instead of perceiving what one thinks and feels, the process is probably better thought of in terms of wondering what to say, or rehearsing a narrative that could be made public: ‘How do I know what I think until I hear what I say?’ Introspection was a particular target of behaviourism in psychology, but the opposition may have been misconceived, since making reports of one’s mental life is itself a piece of behaviour, and one that can be studied as objectively as any other. See heterophenomenology.
