I argue for the existence of imaginative beliefs: mental states that are imaginative in format and doxastic in attitude. I advance two arguments for this thesis. First, there are imaginings that play the functional roles of belief. Second, there are imaginings that play the epistemic roles of belief. These arguments supply both descriptive and normative grounds for positing imaginative beliefs. I also argue that this view fares better than alternatives that posit distinct imaginative and doxastic states to account for the same phenomena. Along the way, I demonstrate the theoretical significance of imaginative beliefs by showing how they pose a challenge for standard taxonomies of the mind, clarify the sense in which imagination is occurrent and voluntary, explain the justificatory role of the imagination, and point to a deep but underappreciated symmetry between imagistic and non-imagistic thought.

The vividness of mental imagery is epistemically relevant. Intuitively, vivid and intense memories are epistemically better than weak and hazy memories, and using a clear and precise mental image in the service of spatial reasoning is epistemically better than using a blurry and imprecise mental image. But how is vividness epistemically relevant? I argue that vividness is higher-order evidence about one’s epistemic state, rather than first-order evidence about the world. More specifically, the vividness of a mental image is higher-order evidence about the amount of first-order information one has about its subject matter. When vividness is sufficiently low, it can give one reason to doubt the epistemic basis of the mental image and thereby act as a defeater. This account has important implications for theorizing about the epistemic roles of memory, imagination, mental imagery, and phenomenal consciousness.

An influential objection to the epistemic power of the imagination holds that it is uninformative. You cannot get more out of the imagination than you put into it, and therefore learning from the imagination is impossible. This paper argues, against this view, that the imagination is robustly informative. Moreover, it defends a novel account of how the imagination informs, according to which the imagination is informative in virtue of its analog representational format. The core idea is that analog representations represent relations ‘for free,’ and this explains how the imagination can contain more information than is put into it. This account makes important contributions to both philosophy of mind, by showing how the imagination can generate new content that is not represented by a subject’s antecedent mental states, and epistemology, by showing how the imagination can generate new justification that is not conferred by a subject’s antecedent evidence.

The imagination is ubiquitous in our cognitive lives. You might imagine rotating a puzzle piece to determine whether it fits in an open space, or imagine what things are like from another person's perspective to figure out how they are feeling, or imagine a new rug in your living room to determine whether it matches the color of your sofa. These examples are mundane, but they point to a deep philosophical puzzle: how could merely imagining something give you any reason to believe that it is true? After all, you can imagine anything you want to, from the fictional to the fantastical. This has led many philosophers to be deeply skeptical of the epistemic value of the imagination. When imagination is accorded a justificatory role, it is typically limited to beliefs about what is metaphysically possible. More recently, some philosophers have begun to push back against this orthodoxy by arguing that the imagination can justify empirical beliefs about the actual world. But even then, most contemporary discussions focus on whether the imagination can justify empirical belief, rather than on how the imagination justifies empirical belief, thereby leaving many central questions about the epistemology of the imagination unanswered. This dissertation attempts to fill this lacuna by canvassing the theoretical landscape of this exciting new literature and developing an account of the epistemic structure of the imagination. The first chapter sets the stage for the rest of the dissertation by reviewing extant arguments for and against the view that the imagination can justify empirical belief before posing a new argument in its favor. The second chapter argues that imaginative justification is mediate but non-inferential; it depends on one’s prior justification without depending on an inference from one’s prior beliefs. The third chapter argues that the imagination is informative—it can represent new content and generate new justification—in virtue of its analog representational format. The fourth and final chapter argues that some imaginings just are beliefs, and that this grounds their justificatory force. Together, the arguments of this dissertation suggest that the imagination is a distinctive kind of ampliative reasoning, and that it plays this cognitive and epistemic role by combining the analog representational format of imagery with the evidence-sensitive function of belief.

This paper develops a theory of analog representation. We first argue that the mark of the analog is to be found in the nature of a representational system’s interpretation function, rather than in its vehicles or contents alone. We then develop the rulebound structure theory of analog representation, according to which analog systems are those that use interpretive rules to map syntactic structural features onto semantic structural features. The theory involves three degree-theoretic measures that capture three independent ways in which a system can be more or less analog. We explain how our theory improves upon prior accounts of analog representation, provides plausible diagnoses for novel challenge cases, extends to hybrid systems that are partially analog and partially symbolic, and accounts for some of the advantages and disadvantages of representing analogically versus symbolically.

Imagination plays a rich epistemic role in our cognitive lives. For example, if I want to learn whether my luggage will fit into the overhead compartment on a plane, I might imagine trying to fit it into the overhead compartment and form a justified belief on the basis of this imagining. But what explains the fact that imagination has the power to justify beliefs, and what is the structure of imaginative justification? In this paper, I answer these questions by arguing that imaginings manifest an epistemic status: they are epistemically evaluable as justified or unjustified. This epistemic status grounds their ability to justify beliefs, and they accrue this status in virtue of being based on evidence. Thus, imaginings are best understood as justified justifiers. I argue for this view by way of showing how it offers a satisfying explanation of certain key features of imaginative justification that would otherwise be puzzling. I also argue that imaginings exhibit a number of markers of the basing relation, which further motivates the view that imaginings can be based on evidence. The arguments in this paper have theoretically fruitful implications not only for the epistemology of imagination, but for accounts of reasoning and epistemic normativity more generally.

This chapter argues that epistemic uses of the imagination are a sui generis form of reasoning. The argument proceeds in two steps. First, there are imaginings which instantiate the epistemic structure of reasoning. Second, reasoning with imagination is not reducible to reasoning with doxastic states. Thus, the epistemic role of the imagination is that it is a distinctive way of reasoning out what follows from our prior evidence. This view has a number of important implications for the epistemology of the imagination. For one thing, it clarifies the epistemic role of widely invoked “constraints” on the imagination. For another, it highlights important and underappreciated disanalogies between how perceptual experiences and imaginings justify beliefs. Ultimately, the view that we can reason with imagination offers an illuminating and theoretically fruitful framework through which to understand the epistemic structure of the imagination.

The proposals gathered under the rubric of “Hilbert Problems” (HPs) demonstrate the progress, the disciplinary maturity, and the distinctive analytical potential of bio-cultural approaches to the study of religion. The HPs identify and investigate the ubiquitous evolutionary, cognitive, and neural processes that undergird the disparate array of religious phenomena. Many of the proposals offer fresh perspectives on conventional components of religion by connecting the study of religion to disciplines as diverse as psychiatry, semiotics, and statistics. In these ways, the HPs demonstrate the naturalness of religion in the evolution of the human species. This short commentary briefly explores the issues of the definition of religion, religion and morality, the naturalistic basis for religious hermeneutics, and tradition-centered research and suggests ways in which the humanities can inform and enrich bio-cultural approaches. It proposes that collaboration between science and the humanities can advance research and help illuminate religion’s relevance to humanity’s lived experience.

In the past two decades a number of arguments have been given in favor of the possibility of phenomenal consciousness without attentional access, otherwise known as phenomenal overflow. This paper will show that the empirical data commonly cited in support of this thesis is, at best, ambiguous between two equally plausible interpretations, one of which does not posit phenomenology beyond attention. Next, after citing evidence for the feature-integration theory of attention, this paper will give an account of the relationship between consciousness and attention that accounts for both the empirical data and our phenomenological intuitions without positing phenomenal consciousness beyond attention. Having undercut the motivations for accepting phenomenal overflow along with having given reasons to think that phenomenal overflow does not occur, I end with the tentative conclusion that attention is a necessary condition for phenomenal consciousness.
