Self-knowledge and imagination

How do we know when we have imagined something? How do we distinguish our imaginings from other kinds of mental states we might have? These questions present serious, if often overlooked, challenges for theories of introspection and self-knowledge. This paper looks specifically at the difficulties imagination creates for Neo-Expressivist, outward-looking, and inner sense theories of self-knowledge. A path forward is then charted, by considering the connection between the kinds of situations in which we can reliably say that another person is imagining, and those in which we can say the same about ourselves. This view is a variation on the outward-looking approach, and preserves much of the spirit of Neo-Expressivism
