The Mental and The Physical
Summary: In this paper the author addresses physicalism and the problem of whether physicalism can account for consciousness and intentionality of our mental states. After providing a good survey of problems posed by this phenomenon as well as possible physicalist responses, she concludes that there still is no satisfying explanation of how the nature of our mental states fits into an “otherwise physical world”.
What can we know a priori?
Abstract: Michael Devitt has been developing an influential two-pronged attack on the a priori for over thirteen years. This attack does not attempt to undermine the coherence or significance of the distinction between the a priori and the a posteriori, but rather to answer the question: ‘What Can We Know A Priori?’ with: ‘Nothing’. In this paper I explain why I am dissatisfied with key extant responses to Devitt’s attack, and then take my own steps towards resisting the attack as it appears in two recent incarnations. Devitt aims firstly to undermine the motivation for believing in any a priori knowledge, and secondly to provide reasons directly against believing in any. I argue that he misidentifies the motivations available to the a priorist, and that his reasons against believing in the a priori do not take account of all the options. I also argue that his attempt to combine the two prongs of the attack into an abductive argument for his anti-a priorist position does not succeed.
Epistemic Value Monism
Introduction: Where does the state of knowledge get its value? Virtually everyone agrees that it comes partly from the value of the truth that is thereby acquired, but most philosophers also agree that knowledge is more valuable than mere true belief. If so, what is the source of the extra value that knowledge has? Curiously, several well-known contemporary epistemic theories have trouble answering this question. In particular, I have argued that reliabilism is unable to explain where knowledge gets its value. I call this the value problem. Sosa addresses the value problem in a recent paper, moving his theory in a more Aristotelian direction. In this chapter I will review the moves Sosa makes to solve the problem and will suggest a simpler approach that I believe does justice to all his desiderata.
Philosophical thought experiments, intuitions, and cognitive equilibrium
Summary: Drawing on literature from the dual-processing tradition in psychology, this paper tries to explain why contemplation of an imaginary particular may have cognitive and motivational effects that differ from those evoked by an abstract description of the same content, and hence, why thought experiments may be effective devices for conceptual reconfiguration. It suggests that by presenting content in a suitably concrete way, thought experiments recruit representational schemas that were otherwise inactive, thereby evoking responses that may run counter to those evoked by alternative presentations of relevantly similar content.
Testimony: Acquiring Knowledge from Others
Introduction: Virtually everything we know depends in some way or other on the testimony of others – what we eat, how things work, where we go, even who we are. We do not, after all, perceive firsthand the preparation of the ingredients in many of our meals, or the construction of the devices we use to get around the world, or the layout of our planet, or our own births and familial histories. These are all things we are told. Indeed, subtracting from our lives the information that we possess via testimony leaves them barely recognizable. Scientific discoveries, battles won and lost, geographical developments, customs and traditions of distant lands – all of these facts would be completely lost to us. It is, therefore, no surprise that the importance of testimony, both epistemological and practical, is nearly universally accepted. Less consensus, however, is found when questions about the nature and extent of our dependence on the word of others arise. Is our justified reliance on testimony fundamentally basic, for instance, or is it ultimately reducible to perception, memory, and reason? Is trust, or some related interpersonal feature of our social interaction with one another, essential to the acquisition of beliefs that are testimonially justified? Is testimonial knowledge necessarily acquired through transmission from speaker to hearer? Can testimony generate epistemic features in its own right? These are the questions that will be taken up in this paper and, as will become clear, their answers have far-reaching consequences for how we understand our place in the social world.
Knowledge and reliability
Internalists have criticised reliabilism for overlooking the importance of the subject’s point of view in the generation of knowledge. This paper argues that there is a troubling ambiguity in the intuitive examples that internalists have used to make their case, and on either way of resolving this ambiguity, reliabilism is untouched. However, the argument used to defend reliabilism against the internalist cases could also be used to defend a more radical form of externalism in epistemology.
Knowledge as a mental state
Abstract: In the philosophical literature on mental states, the paradigmatic examples of mental states are beliefs, desires, intentions, and phenomenal states such as being in pain. The corresponding list in the psychological literature on mental state attribution includes one further member: the state of knowledge. This article examines the reasons why developmental, comparative and social psychologists have classified knowledge as a mental state, while most recent philosophers – with the notable exception of Timothy Williamson – have not. The disagreement is traced back to a difference in how each side understands the relationship between the concepts of knowledge and belief, concepts which are understood in both disciplines to be closely linked. Psychologists and philosophers other than Williamson have generally have disagreed about which of the pair is prior and which is derivative. The rival claims of priority are examined both in the light of philosophical arguments by Williamson and others, and in the light of empirical work on mental state attribution.
Can Belief be Justified through Coherence Alone?
Summary: Elgin and Van Cleve both answer the question in the title negatively. But whereas Van Cleve advocates a moderate version of foundationalism, Elgin defends a broadly coherentist view. According to her, justification is primarily a matter of explanatory coherence. The justification an individual belief enjoys is derived from the coherence of the overall system. In his essay, Van Cleve argues that, although coherence is indeed a source of justification, it cannot by itself render a belief completely justified. According to Van Cleve, no belief could be justified unless it were possible for some beliefs to acquire complete justification without receiving support from any other beliefs. In their respective responses, Elgin and Van Cleve continue the dispute, focusing on issues such as conjunction closure, corroboration by independent witnesses, empirical generalization, revisability, and the skeptical threat of being deluded.
Against Gullibility
Summary: This paper refutes the PR thesis according to which the hearer has such a special presumptive right to trust the speaker’s assertion. The refutation consists of 1) arguing against that it is not possible for a hearer to obtain independent confirmation that a given speaker is trustworthy – that what she says will be true; 2) a full rejection to various positive arguments for a PR which may be made.
