  Martin (2002) compares and contrasts the intentionalist and naïve realist accounts of these phenomenological aspects of perceptual experience and argues that introspective reflection on the nature of sensory imagination—in particular, visualising— gives us reason to support the naïve realist account over the intentionalist one. Martin’s argument for this claim has the following structure: (i) He compares and contrasts the naïve realist and intentionalist accounts of certain aspects of the phenomenology of perceptual experience—their transparency and immediacy. (ii) He argues for a thesis about visualising—the ‘dependency thesis’, which states that to visualise an F is to imagine a visual experience of an F. (For an influential discussion of this idea, see Williams 1973. For an endorsement of the view, see Peacocke 1985 and Vendler 1984.) (iii) He argues that the truth of the dependency thesis should lead the intentionalist and the naïve realist to make different predictions about the phenomenology of visualising, given their different accounts of the transparency and immediacy of perceptual experience. So, he claims, the phenomenology of visualising can be regarded as a test of these competing views. (iv) He argues that the phenomenology of our episodes of visualising favours the naïve realist account.
