To be acquainted with something (in the philosophical sense of “acquainted” discussed here) is to be directly aware of it. The idea that we are acquainted with certain things we experience has been discussed throughout the history of Western Philosophy, but in the early 20th century it gained especially focused attention among analytic philosophers who drew their inspiration from Bertrand Russell's work on acquaintance. Since then, many philosophers—particularly those working on self‐knowledge or perception—have used the notion of acquaintance to explain (...) various facts about human experience and knowledge. In this paper, I offer an overview of this work, with particular focus on the resurgent literature on acquaintance in contemporary analytic philosophy. After more fully explaining what acquaintance is (or is supposed to be), I describe some reasons for thinking that we are indeed acquainted with certain things we experience, and then I survey some of the facts about experience and knowledge that acquaintance may help explain.

This article is on a precise kind of color primitivism, ‘ostensivism.’ This is the view that it is in the nature of the colors that they are phenomenal, non-reductive, structural, categorical properties. First, I differentiate ostensivism from other precise forms of primitivism. Next, I examine the core belief ‘Revelation,’ and propose a revised version, which, unlike standard statements, is compatible with a yet unstated but plausible core belief: roughly, that there are interesting things to be discovered about the nature of (...) the colors. Finally, I show that ostensivism is the only view on color that can accommodate both proposed core beliefs. (shrink)

The “problem of memory” in epistemology is concerned with whether and how we could have knowledge, or at least justification, for trusting our apparent memories. I defend an inductive solution—more precisely, an abductive solution—to the problem. A natural worry is that any such solution would be circular, for it would have to depend on memory. I argue that belief in the reliability of memory can be justified from the armchair, without relying on memory. The justification is, roughly, that my having (...) the sort of experience that my apparent memory should lead me to expect is best explained by the hypothesis that my memories are reliable. My solution is inspired by Harrod’s (1942) inductive solution. Coburn (1960) argued that Harrod’s solution contains a fatal flaw. I show that my solution is not vulnerable to Coburn’s objection, and respond to a number of other, recent and likely objections. (shrink)

Can a belief source confer justification when we lack antecedent justification for believing that it’s reliable? A negative answer quickly leads to skepticism. A positive answer, however, seems to commit one to allowing pernicious reasoning known as “epistemic bootstrapping.” Puzzles surrounding bootstrapping arise because we illicitly assume either that justification requires doxastic awareness of a source’s epistemic credentials or that there is no requirement that a subject be aware of these credentials. We can resolve the puzzle by splitting the horns (...) and requiring a non-conceptual awareness of, or direct acquaintance with, a source’s legitimacy. Requiring non-conceptual as opposed to doxastic awareness halts the regress and avoids the skeptical results. On the other hand, requiring non-conceptual awareness also guarantees that we are aware of evidence for a source’s reliability prior to using that source to form justified beliefs; we thereby avoid the problem of allowing epistemic bootstrapping to generate the illicit gains in justification.

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.

This paper will be concerned with the role acquaintance plays in contemporary theories of introspection. Traditionally, the relation of acquaintance has been conceived in analytic epistemology and philosophy of mind as being only epistemically relevant inasmuch as it causes, or enables, or justifies a peculiar kind of propositional knowledge, i.e., knowledge by acquaintance. However, in recent years a novel account of the role of acquaintance in our introspective knowledge has been offered. According to this novel constitutive approach, acquaintance is, in (...) itself, a sui generis—i.e., non-propositional—kind of knowledge. As we will suggest, a stalemate between David Chalmers’ account of direct phenomenal concepts—as a prototypical example of a causal view—and Anna Giustina’s account of primitive introspection—as a prototypical example of a constitutive view—is looming in the current controversy between the two families of theories. Towards the end of the essay, we will point to some possible ways for a constitutive theorist to break the stalemate. (shrink)

In this chapter, we examine different views of the structure of justification, including foundationalism, infinitism, and coherentism. We investigate how well or poorly they seem to do in responding to the regress problem, accommodating a robust connection between justification and truth, and getting the contours of justification right—i.e., making justification neither too easy nor too hard to get. We end by briefly discussing some challenges to finding a single sense of “foundational belief” defining the debate.

Experiential acquaintance is an alleged relation between ourselves and our experiences that has sometimes been hypothesised as necessary for knowledge of our experiences. This paper begins with a clarification of ‘acquaintance’ and an explanation of ‘experience’ that focuses attention on a famous, but flawed, argument by G. E. Moore. It goes on to critically examine several recent arguments concerning experiential acquaintance and to show how internalist foundationalism can respond to a famous Sellarsian dilemma without appeal to a relation of acquaintance (...) with our experiences. It concludes that we can dispense with experiential acquaintance. (shrink)

The role of emergence in the creation of consciousness has been debated for over a century, but it remains unresolved. In particular there is controversy over the claim that a “strong” or radical form of emergence is required to explain phenomenal consciousness. In this paper we use some ideas of complex system theory to trace the emergent features of life and then of complex brains through three progressive stages or levels: Level 1 (life), Level 2 (nervous systems), and Level 3 (...) (special neurobiological features), each representing increasing biological and neurobiological complexity and ultimately leading to the emergence of phenomenal consciousness, all in physical systems. Along the way we show that consciousness fits the criteria of an emergent property—albeit one with extreme complexity. The formulation Life + Special neurobiological features → Phenomenal consciousness expresses these relationships. Then we consider the implications of our findings for some of the philosophical conundrums entailed by the apparent “explanatory gap” between the brain and phenomenal consciousness. We conclude that consciousness stems from the personal life of an organism with the addition of a complex nervous system that is ideally suited to maximize emergent neurobiological features and that it is an example of standard (“weak”) emergence without a scientific explanatory gap. An “experiential” or epistemic gap remains, although this is ontologically untroubling. (shrink)

There are two kinds of epistemic theories about self-knowledge: the traditional account, and the inferentialist account. According to the traditional view of self-knowledge, we have privileged access to our propositional attitudes. “Privileged access” means that one can gain knowledge of one’s own propositional attitudes directly via an exclusive, first-personal method called introspection. On the other hand, the inferentialist view of self-knowledge postulates that we don’t have privileged access to our propositional attitudes and must infer or self-attribute them instead. In this (...) thesis I argue that the traditional view of self-knowledge, which postulates that we have privileged access to our propositional attitudes, ought to be abandoned in favor of an infernetialist picture of self-knowledge I argue that recent experimental results in social psychology strongly imply that we don’t have privileged access to our propositional attitudes. In the choice blindness paradigm, the majority of participants can be manipulated into becoming oblivious to choices that they made just moments previously. Not only do participants utterly fail to notice that they did not receive what they wanted, but they also provide confabulated reasons as to why they made their “decision.” I maintain that the phenomena of choice blindness and confabulation are very difficult for the traditional theory of self- knowledge to accommodate and explain; whereas, on the other hand, the inferentialist account actually predicts and anticipates these experimental findings. The traditional theorist cannot avoid the threat that choice blindness and confabulation pose by restricting the scope of privileged access even further, to exclude propositional attitudes, because privileged access to propositional attitudes is the very property which distinguishes the traditional view of self-knowledge from an inferentialist account. The traditional theorist might attempt to argue that privileged access to propositional attitudes is conceptually necessary, but I maintain that this argument fails. The traditional theorist’s only option, then, is to adopt a dual-method account whereby we sometimes gain self-knowledge via introspection and sometimes via inference. However, I maintain that the dual-method approach is a much weaker theory in terms of explanatory power when compared to the inferentialist account. On balance, then, the traditional view of self-knowledge should be rejected in favor of the inferentialist account. (shrink)
