 Finally, varieties of imagination might be classified in terms of their structure and content. Consider the following three types of imaginings, each illustrated with an example. When one imagines propositionally, one represents to oneself that something is the case. So, for example, Juliet might imagine that Romeo is by her side. To imagine in this sense is to stand in some mental relation to a particular proposition (see the entry on  propositional attitude reports).  When one imagines objectually, one represents to oneself a real or make-believe entity or situation (Yablo 1993; see also Martin 2002; Noordhof 2002; O’Shaughnessy 2000). So, for example, Prospero might imagine an acorn or a nymph or the city of Naples or a wedding feast. To imagine in this sense is to stand in some mental relation to a representation of an (imaginary or real) entity or state of affairs. When one imagines X-ing, one simulatively represents to oneself some sort of activity or experience (Walton 1990). So, for example, Ophelia might imagine seeing Hamlet or getting herself to a nunnery. To imagine in this sense is to stand in a first-personal mental relation to some (imaginary or real) behavior or perception.
