When David Lewis ( 1986 ) told us that possible worlds were a ‘paradise for philosophers’, he neglected to add that they are a minefield for decision theorists. Possibilities — be they nomological, metaphysical, or epistemic possibilities — have little to do with subjective probabilities, and it is these latter that matter most to decision theory. Bernard Katz and Doris Olin ( 2007 ) have tried to solve the two-envelope problem by appealing to possible worlds and counterfactual conditionals. In this (...) article, I explain why any such attempt is misguided, and why we, qua decision theorists, must focus on the probable rather than the possible. (shrink)

I am justified in believing that my lottery ticket—call it t1—will not win, on statistical grounds. Those grounds apply equally to any other ticket, so I am justified in believing of any other ticket ti (let i take values from 2 to 1000000) that it will not win. I am not, however, justified in believing the giant conjunctive proposition that t1 will not win & t2 will not win & . . . & t1,000,000 will not win. On the contrary, (...) I am justified in believing that some ticket will win, hence that one of those conjuncts is false. Suggested solution: justified belief is not closed under conjunction. It does not follow from the fact that I am justified in believing p and justified in believing q that I am justified in believing p & q. (shrink)

We have a striking ability to alter our psychological access to past experiences. Consider the following case. Andrew “Nicky” Barr, OBE, MC, DFC, (1915 – 2006) was one of Australia’s most decorated World War II fighter pilots. He was the top ace of the Western Desert’s 3 Squadron, the pre-eminent fighter squadron in the Middle East, flying P-40 Kittyhawks over Africa. From October 1941, when Nicky Barr’s war began, he flew 22 missions and shot down eight enemy planes in his (...) first 35 operational hours. He was shot down three times, once 25 miles behind enemy lines while trying to rescue a downed pilot. He escaped from prisoner of war camps four times, once jumping out of a train as it travelled from Italy into Austria. His wife Dot, who he married only weeks before the war, waited for him at home. She was told on at least three occasions that he was missing in action or dead. For 50 years, Nicky Barr never spoke publicly, and rarely privately, of his war-time experiences. He was very much a forgotten and forgetting hero (for further details, see Dornan, 2002). In his first public interview in 2002 on the Australian documentary program “Australian Story”, Nicky explained his 50 year silence by saying. (shrink)

1. The restless mind[1] Like us, early modern philosophers, both natural and moral, didn’t always understand the springs of their own actions. They didn’t want to feel everything they felt, and couldn’t trace the sources of all their thoughts and imaginings. Events from past experience come to mind again unwilled: abstract thought is interrupted by fantastical images, like the ‘winged horses, fiery dragons, and monstrous giants’ by which Hume exemplified ‘the liberty of the imagination’[2]. Then, as now, a failure to (...) keep a train of thought on track could be blamed for both personal and social ills, for wasted lives and erratic policies. The ongoing struggle to distinguish the deliverances of reason from what Hume called ‘the loose and indolent reveries of a castle-builder’ (1739/ 1978, p.624) thus required scrutiny of daydream and fancy as much as belief and knowledge (see also Tierney- Hynes 2007 on the ‘castle-builder’). The mind’s tendencies to float and to roam were of great interest to early modern philosophers as well as to others concerned with medicine, mental health, morals, education, and taste. This paper sketches one local line of thinking and theorizing about ‘mind-wandering’ and its bodily causes in British philosophy over the first decades of the 18th century, as a small exemplar of a form of cognitive history intended to illuminate independent historical and contemporary concerns about our understanding of mental life. The dual aim is to see problems in our historical material that we might otherwise miss, and to use history to explore phenomena more or less marginalized by modern psychology[3]. (shrink)

I will be arguing that a subject’s belief that p is justified if and only if he knows that p: justification is knowledge. I will start by describing two broad classes of allegedly justified beliefs that do not constitute knowledge and which, hence, cannot be what they are often taken to be if my view is correct. It is far from clear what my view is until I say a lot more about the relevant concept or concepts of justification that (...) concern me. The following section describes several concepts of justification that epistemologists have employed, and, in particular, identifies the two concepts of justification that I claim are coextensive with the concept of knowledge. One of those is the deontological conception of justification: I will be arguing that one ought not believe that p unless one knows that p. I imagine that the major opposition to my view will be that it is simply obvious that there are justified false beliefs, a feeling that I try to dispel in the lengthy section on concepts of justification before I finally get around to giving the main arguments in favor of my view. A view as unorthodox as mine demands more than a single argument: I offer four in the third section. Everyone allows that many people have many unjustified beliefs, and everyone has some unjustified beliefs, but such beliefs appear to be far more prevalent on my view than on more orthodox views. In the last section, I argue that unjustified beliefs, although widespread, are not quite as common as they might appear to be on my view. (shrink)

The Psychological Study of Social Memory Phenomena Very often our memories of the past are of experiences or events we shared with others. And “in many circumstances in society, remembering is a social event” (Roediger, Bergman, & Meade, 2000, p.129): parents and children reminisce about significant family events, friends discuss a movie they just saw together, students study for exams with their roommates, colleagues remind one another of information relevant to an important group decision, and complete strangers discuss a crime (...) they happened to witness together. Psychology is at the heart of recent interdisciplinary efforts to understand the relationships between an individual remembering alone, an individual remembering in a group, and the group itself remembering.

This rich book, the best I’ve read in consciousness studies, offers more at each encounter. It was a brilliant idea to evaluate Hurlburt’s Descriptive Experience Sampling (DES) method through concrete sceptical enquiry by Schwitzgebel, whose role as open-minded but hard-nosed interlocutor makes the debate an intriguing, even gripping read. The radically different views about introspective reports held by the two authors (hereafter Russ and Eric, following the book’s informality) are put to the test in the concrete context of ‘an examination, (...) in unprecedented detail, of random moments of one person’s experience’ (p. 11).1 In addition to the ongoing central pursuit of the general question ‘Can we believe people’s reports about their inner experience?’, a raft of more specific issues (from the speed of an ‘inner voice’, through theories of emotion, to the indeterminacy of images) are addressed as they arise in the sampling interviews. The book’s excellent organization, using in-text boxes linked by detailed crossreferencing into indexed threads, reinforces the thrilling sense that our access to the inner life of one person, ‘Melanie’, is bringing real progress on a number of fronts at once. Eric’s robust scepticism remains, but is tempered somewhat by being forced to confront the real constraints and opportunities of gathering information from a live subject. By the end of the project, he accepts that Russ’s ‘beep-andinterview methods’ deserve a central role in introspective science (p. (shrink)

In Without Justification,[1] Jonathan Sutton undermines the orthodox view that a justified belief needn’t constitute knowledge; develops a battery of arguments for the unorthodox thesis that you justifiedly believe P iff you know P; and explores the topics of testimony and inference in light of his equation of justification and knowledge (J=K). This book is essential reading at epistemology’s cutting edge. In §I, we’ll take an extended tour of the book, raising various questions and objections along the way. In (...) §II, we’ll assess Sutton’s three main arguments for J=K, which form the heart of his project. (shrink)

Analytic epistemologists agree that, whatever else is true of epistemic justification, it is distinct from knowledge. However, if recent work by Jonathan Sutton is correct, this view is deeply mistaken, for according to Sutton justification is knowledge. That is, a subject is justified in believing that p iff he knows that p. Sutton further claims that there is no concept of epistemic justification distinct from knowledge. Since knowledge is factive, a consequence of Sutton’s view is that (...) there are no false justified beliefs. <br> Following Sutton, I will begin by outlining kinds of beliefs that do not constitute knowledge but that seem to be justified. I will then be in a position to critically evaluate Sutton’s arguments for his position that justification is knowledge, concluding that he fails to establish his bold thesis. In the course of so doing, I will defend the following rule of assertion: (The JBK-rule) One must: assert p only if one has justification to believe that one knows that p.<br>. (shrink)

Grounded theory is examined as a means of undertaking economics research that aims at theoretical development and generalization rather than testing established theories. Grounded theory encompasses a set of procedures for undertaking and analysing case studies--qualitative and quantitative--in a systematic and comparative manner. These procedures are set out, and illustrations of theory developed in close connection with business decision-making and industry competition are drawn from P.W.S. Andrews' post-Marshallian industry studies, Cyert and March's Behavioral Theory of the Firm , and (...) class='Hi'>Sutton's analysis of market structures. Conclusions are drawn out regarding the nature of the relationship between testing established theory and making novel knowledge claims, the nature of knowledge held by those involved in economic phenomena, the nature of contexts of discovery and verification, and processes involved in making inferences.
