A comprehensive theory of the structure and cognitive function of the human imagination, and its relationship to perceptual experience, is developed, largely through a critique of the account propounded in Colin McGinn's Mindsight. McGinn eschews the highly deflationary (and unilluminating) views of imagination common amongst analytical philosophers, but fails to develop his own account satisfactorily because (owing to a scientifically outmoded understanding of visual perception) he draws an excessively sharp, qualitative distinction between imagination and perception (following Wittgenstein, Sartre, and others), and because of his fatally flawed, empirically ungrounded conception of hallucination. In fact, however, an understanding of perception informed by modern visual science will enable us to unify our accounts of perception, mental imagery, dreaming, hallucination, creativity, and other aspects of imagination within a single coherent theoretical framework.

The aim of this article is to expand the diet of examples considered in philosophical discussions of imagination and pretense, and to offer some preliminary observations about what we might learn about the nature of imagination as a result. The article presents a number of cases involving imaginative contagion: cases where merely imagining or pretending that P has effects that we would expect only perceiving or believing that P to have. Examples are offered that involve visual imagery, motor imagery, fictional emotions, and social priming. It is suggested that imaginative contagion is a more prevalent phenomenon than has typically been recognized.

This article defends tradition and common sense against a widespread and rarely questioned contemporary philosophical orthodoxy that underpins the entrenched and exorbitant "lingualism" of so much 20th century thought, and leads the way to extreme doctrines like cognitive relativism and eliminative materialism. It also plugs what might otherwise have seemed to be a significant hole in the argument of my Are Theories of Imagery Theories of Imagination? (which I regard as my main positive contribution so far to the understanding of the mind). For a relatively brief overview of the situation in cognitive theory and consciousness studies, as I see it, see A Stimulus to the Imagination.

"Imagination", says Aristotle, "is the process by which we say that an image is presented to us."1 While the OED accepts at least five other entries for the word -- including, for instance, poetic genius -- its first entry refers to the production of mental images. So in this paper, the one and only way I will use the term imagination is in reference to images.

The question of the imagination is rather like the question Augustine raised with regard to the nature of time. We all seem to know what it involves, yet find it difficult to define. For Descartes, the imagination was simply our faculty for producing a mental image. He distinguished it from the understanding by noting that while the notion of a thousand sided figure was comprehensible—that is, was sufficiently clear and distinct to be differentiated from a thousand and one sided figure—the figure could not be clearly pictured in our mind. The representation of its sides exceeded our powers of imagination.[i] This view of the imagination as our ability to produce a mental image fails, however, to distinguish it from remembering. Let us say that I see an object and then I close my eyes, maintaining the image of the object. Is this imagining or short term memory? What about the case when I recall this image an hour later? Am I imagining or remembering it? Such examples make it clear that imagination, as distinct from memory, implies something more than the ability to produce a mental image. It involves, as Sartre pointed out, a certain attitude towards this image. Engaging in it, we deny its reality. In Sartre’s words, imagination “carries within it a double negation; first, it is the nihilation of the world (since the world is not offering the imagined object as an actual object of perception), secondly, the nihilation of the object of the image (it is posited as not actual) ...” (BN, p. 62). Imagination, then, represents the imagined as nonactual.

This paper explores the question whether an adequate account of the facts about imagination and mental imagery must construe mental images as objects. Much of the paper is a study of Alastair Hannay's defense of an affirmative answer in his wide?ranging study, Mental Images ? A Defence. The paper first sets out and evaluates Hannay's case. The second part develops an alternative account of mental images, including non?visual images, which Hannay does not treat in detail. The alternative account is analogous to the adverbial theory of perception; and it is suggested how this account, without construing mental images as objects, might accommodate the data from which Hannay argues for their objecthood.

Both imagery and imagination play an important part in our mental lives. This article, which has three main sections, discusses both of these phenomena, and the connection between them. The first part discusses mental images and, in particular, the dispute about their representational nature that has become known as the _imagery debate_ . The second part turns to the faculty of the imagination, discussing the long philosophical tradition linking mental imagery and the imagination—a tradition that came under attack in the early part of the twentieth century with the rise of behaviorism. Finally, the third part of this article examines modal epistemology, where the imagination has been thought to serve an important philosophical function, namely, as a guide to possibility.
