Content disjunctivism is the view that veridical experience involves contents and objects that differ from those of corresponding hallucinations. On one formulation of this view, we are aware of ordinary material things in our surroundings when we experience veridically, and we are aware of mere appearances when we hallucinate. This paper proposes a way of developing this view and offers some considerations in support. Central to the proposed regimentation will be a distinction between different notions of appearance. We distinguish between (...) the notion of something merely appearing to have a property and the notion of mere appearances, which are types of objects that we can refer to and be aware of. Mere appearances are not sense data or Meinongian non-existent objects but existing objects that do not have the properties that they appear to have. These notions of appearance will be elucidated, in particular by characterizing how they are involved in hallucination and illusion. I argue that the resulting view is supported by how our mental life seems to us when we experience our environment. (shrink)

Kant’s conception of the centrality of intellectual self-consciousness, or “pure apperception”, for scientific knowledge of nature is well known, if still obscure. Here I argue that, for Kant, at least one central role for such self-consciousness lies in the acquisition of the content of concepts central to metaphysical theorizing. I focus on one important concept, that of <substance>. I argue that, for Kant, the representational content of the concept <substance> depends not just on the capacity for apperception, but on the (...) actual intellectual awareness of oneself in such apperception. I then defend this interpretation from a variety of objections. (shrink)

The purpose of this thesis is to provide a metaphysic for moral realism and moral perception. This thesis is in two parts. The first is concerned with basic ontology. I begin in chapter 1 with an analysis of causation, demonstrating that substance theory is superior to Humeanism at accounting for our observations; thus I defend a substance ontology. In chapter 2, I address human agency, demonstrating that reasons internalism does not allow for incompatibilist freedom; hence, I affirm reasons are states (...) of affairs. I move on to qualia in chapter 3, demonstrating that arguments both for and against qualia realism involve question begging. In response, I argue that qualia realism is just as reasonable as anti-realism, and affirm realism. Given this, I address the mind-body problem in chapter 4, demonstrating the failure of physicalists to account for mental causation. I conclude that panpsychism, idealism, and substance dualism are equal reasonable alternatives: each allows for intrinsic properties, which are integral to substance ontology. The second part builds a moral ontology, along with an account of moral perceptual knowledge, compatible with the above basic ontology. In chapter 5, I reject moral properties as monadic since this would bar mapping moral concepts onto mind-independent reality. Instead, I argue that moral properties are relations. More specifically, in chapter 6, I make the case that they are features of relations, relations themselves being the total complex states of affairs between one or more substances. This allows moral properties to have their own nonreducible phenomenal quality. To account for moral normativity, I argue that moral features are actually a class of causal features, and briefly argue that final causes determine the normative causal trajectory of all substances. In chapter 7, I conclude this thesis with addressing possible objections to my theory of perception and perceptual knowledge. (shrink)

There are many important dimensions of epistemic evaluation, one of which is justification. We don’t just evaluate beliefs for truth, reliability, accuracy, and knowledge, but also for justification. However, in the epistemological literature, there is much disagreement about the nature of justification and how it should be understood. One of the controversies that has separated the contemporary epistemological discourse into two opposing camps has to do with the internalism-externalism distinction. Whereas internalists defend certain core assumptions about justification from the pre-Gettier (...) tradition, externalists generally think that the traditional conception is untenable and should be replaced. In this compilation thesis, I argue for, defend, and develop a particular brand of internalism, both in general and with respect to specific sources of justification. In papers 1 and 2, I defend a couple of well-known arguments for mentalism and accessibilism. Moreover, I also point out how prominent versions of these theses are vulnerable to serious problems (e.g., about over-intellectualization and vicious regresses). Part of my goal in the first couple of papers is to figure out what commitments the internalist should take on in order to avoid the externalist's objections, while at the same time receiving support from considerations that have motivated internalism in the past. In papers 3 and 4, I start from the assumption that mentalism is true and attempt to answer the following questions: 1) which non-factive mental states can play a justification-conferring role with respect to empirical belief? And 2) why does this set of states play the epistemic role it does? In response to question 1, I argue that all and only one's beliefs and perceptual experiences have justificatory relevance. In response to question 2, I argue that one's beliefs and perceptual experiences are one's strongly representational states, and that strongly representational states necessarily provide support to certain empirical propositions. Having done so, I then defend mentalism about scientific evidence from a couple of prominent objections in the recent literature. Lastly, in papers 5 and 6, I argue for a particular brand of internalism about testimonial and memorial justification and show how that position has a dialectical advantage over its main competitors.

The essay is a study of phenomenal specificity. By ‘phenomenal’ here we mean conscious awareness, which needs to be cashed out in detail throughout the study. Intuitively, one dimension of phenomenology is along with specificity. For example it seems appropriate to say that one’s conscious awareness in the middle of the visual field is in some sense more specific than the awareness in the periphery under normal circumstances. However, it is difficult to characterise the nature of phenomenal specificity in an (...) accurate way. This essay seeks to do just that. In the introduction, I set up the discussion by invoking a threefold Campbellian framework. Chapter 1 introduces a key notion of the analogue, its roots in sciences, and its applications in philosophy. Chapter 2 focuses on the major case study – the Sperling iconic memory paradigm – and explains how the relevant notion of the analogue can be used to explain phenomenal specificity involved in the Sperling case. Chapter 3 discusses functions of attention, as it is a crucial element in the Sperling case. Chapter 4 extends the project by explaining how visual demonstratives fit into the present picture. Finally chapter 5 discusses several directions for future researches. This essay is not an attempt to discuss all the issues concerning the Sperling case, but to provide a new angle in seeing the issue: most people agree that visual phenomenology is in some sense specific, but there are not enough attempts to model phenomenal specificity explicitly. On this occasion we use a notion of the analogue and related ideas to understand phenomenal specificity and how it applies to certain empirical cases. (shrink)

Naïve realism, often overlooked among philosophical theories of perception, has in recent years attracted a surge of interest. Broadly speaking, the central commitment of naïve realism is that mind-independent objects are essential to the fundamental analysis of perceptual experience. Since the claims of naïve realism concern the essential metaphysical structure of conscious perception, its truth or falsity is of central importance to a wide range of topics, including the explanation of semantic reference and representational content, the nature of phenomenal consciousness, (...) and the basis of perceptual justification and knowledge. One of the greatest difficulties surrounding discussions of naïve realism, however, has been lack of clarity concerning exactly what affirming or denying it entails. In particular, it is sometimes unclear how naïve realism is related to the claim that perceptual experience is in some sense direct or unmediated, and also to what extent the view is compatible with another widely discussed thesis in the philosophy of perception, the claim that perceptual experiences are states with representational content. In this essay, I discuss how recent work on these issues helps to clarify both the central commitments of naïve realism, as well as its relation to representationalist theories of perception. Along the way, I will attempt to shed light on the different ways in which each approach tries to address the various theoretical challenges facing a philosophical theory of perception, and also to assess the prospects for views that attempts to combine features of each approach.

A defense of the idea that knowledge is first in the sense that there is nothing prior to knowledge that puts reasons or evidence in your possession. Includes a critical discussion of the idea that perception or perceptual experience might provide reasons and a defense of a knowledge-first approach to justified belief.

When we perceive we are under the impression of being directly aware of concrete, mindindependent objects. We also consider perception as a basic, reliable source for acquiring beliefs and an effective means for coping with the environment. In the philosophical literature, this direct and basic character of perception is sometimes captured by saying that perception is openness to the world. Articulating, refining and vindicating as far as possible this commonsensical view of perception as openness to the world is the main (...) objective of this work. In order to make the metaphor of openness tractable in theoretical terms, I set up the dialectic in terms of a contrast between representationalism, which holds that perception represents things as being a certain way, and pure relationalism, which holds that perception can be openness to the world only by being a non-representational relation between a subject and objects in the world. The main thesis that I defend with several arguments in this work is that perception is both representational and relational. Indeed, it intelligibly relates us to the world in virtue of its representational content. In chapter one, I place perception in the broader context of intentional states. I articulate a view on which intentional states are directed toward their objects in virtue of having representational content, and show that prima facie the arguments for thinking that paradigmatic intentional states such as belief have content apply to perception too. I also explain why pure relationalists would reject the application of the content-model to perception. Chapter two is devoted to Charles Travis’s argument that perceptual experience does not have content. I counter his argument by offering a phenomenological account of perceptual constancy, and I show that content is necessary for capturing constancy in theoretical terms. Further, I argue that content helps us to better explain how the mind-independent nature of concrete objects is manifest in the phenomenology of perceptual experience. Chapter three concerns the question of how we should elucidate perceptual experience as openness to the world in the face of illusion and hallucination. I consider three possible approaches, and I argue that a view on which perceptual experience is both representational and relational can best make sense of the relevant phenomena. In the fourth chapter, I consider the debate on phenomenal character between representationalist and purely relationalist views in light of a distinction between particularity and generality. I show how representationalists are committed to there being an element of generality in perception, and how pure relationalists construe perception as wholly particular instead. I defend the representationalist view on the grounds that generality is necessary to make sense of the phenomenal and epistemic determinacy of perception. In the concluding remarks, I consider the question of whether my view can make room for the relationality of perception, and I argue again that only a distorted view of the metaphor of openness to the world could lead one to think that content and relationality are incompatible.

I argue that an analogy between pains and sounds suggests a way to give an objective account of pain which fits well with a naïve perceptualist account of feeling pain. According to the proposed metaphysical account, pains are relational physical events with shared qualitative nature, each of which is constituted by tissue damage and the activation of nociceptors. I proceed to show that the metaphysical proposal is compatible with platitudes about pains being animate, private, and self-intimating states.
