Two methods have been used in the investigation of the stakes-sensitivity of knowledge as it occurs in ordinary language: (a) asking participants about the truth or acceptability of knowledge ascriptions and (b) asking participants how much evidence someone needs to gather before they know that something is the case. This second, “evidence-seeking”, method has reliably found effects of stakes-sensitivity while the method of asking about knowledge ascriptions has not. Consistent with this pattern, in Francis et al. (Ergo, 2019), we found (...) evidence of scalar stakes effects using an evidence-seeking approach. Whilst we found this evidence across several cases using both negative (“don’t know”) and positive (“know”) polarities, there remain questions about the directness of the relationship between stakes and knowledge ascriptions; it is possible that stakes are affecting knowledge by affecting the confidence of the attributor. For example, Bach (in: Peter & Preyer, 2005) has argued that knowledge attributions do not track truth attributions but rather thresholds for doxastic confidence. To investigate the role of confidence in knowledge ascriptions, we use our existing paradigm (Francis et al., 2019) but include measures of both participant and protagonist confidence. As far as we are aware, this is the first empirical investigation of the role of confidence in stakes effects on knowledge that incorporates an evidence-seeking approach using several scenarios. Overall, across both positive (“know”) and negative (“don’t know”) polarity conditions, we find further evidence of a stakes effect on knowledge using an evidence-seeking paradigm. However, and importantly, we do not find evidence that changes in participant confidence partially or fully mediate the stakes effect on knowledge. (shrink)

The data presented in the target article make a persuasive case for the notion that there is a fundamental limit on short term memory (STM) of about four items. Two possible means of further testing this claim are suggested and data regarding scene coherence and memory capacity for ordered information are reviewed.

Page's target article presents an argument for the use of localist, connectionist models in future psychological theorising. The “manifesto” marshalls a set of arguments in favour of localist connectionism and against distributed connectionism, but in doing so misses a larger argument concerning the level of psychological explanation that is appropriate to a given domain.

There is conflicting experimental evidence about whether the “stakes” or importance of being wrong affect judgments about whether a subject knows a proposition. To date, judgments about stakes effects on knowledge have been investigated using binary paradigms: responses to “low” stakes cases are compared with responses to “high stakes” cases. However, stakes or importance are not binary properties—they are scalar: whether a situation is “high” or “low” stakes is a matter of degree. So far, no experimental work has investigated the (...) scalar nature of stakes effects on knowledge: do stakes effects increase as the stakes get higher? Do stakes effects only appear once a certain threshold of stakes has been crossed? Does the effect plateau at a certain point? To address these questions, we conducted experiments that probe for the scalarity of stakes effects using several experimental approaches. We found evidence of scalar stakes effects using an “evidence seeking” experimental design, but no evidence of scalar effects using a traditional “evidence-fixed” experimental design. In addition, using the evidence-seeking design, we uncovered a large, but previously unnoticed framing effect on whether participants are skeptical about whether someone can know something, no matter how much evidence they have. The rate of skeptical responses and the rate at which participants were willing to attribute “lazy knowledge”—that someone can know something without having to check—were themselves subject to a stakes effect: participants were more skeptical when the stakes were higher, and more prone to attribute lazy knowledge when the stakes were lower. We argue that the novel skeptical stakes effect provides resources to respond to criticisms of the evidence-seeking approach that argue that it does not target knowledge. (shrink)

The tendency to neglect base-rates in judgment under uncertainty may be as Barbey & Sloman (B&S) suggest, but it is neither inevitable (as they document; see also Koehler 1996) nor unique. Here we would like to point out another line of evidence connecting ecological rationality to dual processes, the failure of individuals to appropriately judge cumulative probability.

The utility of an “ecologically rational” recognition‐based decision rule in multichoice decision problems is analyzed, varying the type of judgment required (greater or lesser). The maximum size and range of a counterintuitive advantage associated with recognition‐based judgment (the “less‐is‐more effect”) is identified for a range of cue validity values. Greater ranges of the less‐is‐more effect occur when participants are asked which is the greatest of m choices (m > 2) than which is the least. Less‐is‐more effects also have greater range (...) for larger values of m. This implies that the classic two‐alternative forced choice task, as studied by, may not be the most appropriate test case for less‐is‐more effects. (shrink)

Hilbert's program attempts to show that our mathematical knowledge can be certain because we are able to know for certain the truths of elementary arithmetic. I argue that, in the absence of a theory of mathematical truth, Hilbert does not have a complete theory of our arithmetical knowledge. Further, while his deployment of a Kantian notion of intuition seems to promise an answer to scepticism, there is no way to complete Hilbert's epistemology which would answer to his avowed aims.

In this paper, we define some consequence relations based on supervaluation semantics for partial models, and we investigate their properties. For our main consequence relation, we show that natural versions of the following fail: upwards and downwards Lowenheim-Skolem, axiomatizability, and compactness. We also consider an alternate version for supervaluation semantics, and show both axiomatizability and compactness for the resulting consequence relation.

We begin to fill a lacuna in the relevance logic enterprise by providing a foundational analysis of identity in relevance logic. We consider rival interpretations of identity in this context, settling on the relevant indiscernibility interpretation, an interpretation related to Dunn's relevant predication project. We propose a general test for the stability of an axiomatisation of identity, relative to this interpretation, and we put various axiomatisations to this test. We fill our discussion out with both formal and philosophical remarks on (...) identity in relevance logic. (shrink)

There is a growing trend among some physicians, psychiatrists, bioethicists, and other mental health professionals not to treat physician-assisted suicide (PAS) as suicide. The grounds for doing so are that PAS fundamentally differs from other suicides. Perhaps most notably, in 2017 the American Association of Suicidology argued that PAS is distinct from the behavior that their organization seeks to prevent. This paper compares and contrasts suicide and PAS in order to see how much overlap there is. Contrary to the emerging (...) view that emphasizes their differences, I argue that there is significant overlap such that we ought not to separate PAS into its own category, making it diverge from how we think about and address suicide more generally. I start by examining several prominent theories of suicide and argue that PAS fits squarely within them. I then examine several apparent differences between PAS and other kinds of suicide and argue that these differences are merely apparent or they do not justify treating PAS as a fundamentally different kind of thing from suicide.

Presents a contemporary version of the natural law tradition as a valid approach to ethical problems.

We show that assuming modest large cardinals, there is a definable class of ordinals, closed and unbounded beneath every uncountable cardinal, so that for any closed and unbounded subclasses $P, Q, {\langle L[P],\in,P \rangle }$ and ${\langle L[Q],\in,Q \rangle }$ possess the same reals, satisfy the Generalised Continuum Hypothesis, and moreover are elementarily equivalent. Examples of such P are Card, the class of uncountable cardinals, I the uniform indiscernibles, or for any n the class $C^{n}{=_{{\operatorname {df}}}}\{ \lambda \, | \, (...) V_{\lambda } \prec _{{\Sigma }_{n}}V\}$ ; moreover the theory of such models is invariant under ZFC-preserving extensions. They also all have a rich structure satisfying many of the usual combinatorial principles and a definable wellorder of the reals. The inner model constructed using definability in the language augmented by the Härtig quantifier is thus also characterized. (shrink)

From recent writings of Brent Mundy and Michael Friedman we reconstruct two different representation-theoretic or embedding accounts of space-time relationalism, involving two different conditions on embeddings: respectively, uniqueness up to symmetry and uniqueness up to indistinguishability. We discuss the properties of these two accounts, and, with respect specifically to Friedman's projects, assess their merits and demerits.

: Philosophers in the analytic and phenomenological traditions have interpreted Brentano's intentionality thesis, and his empirical psychology more generally, in significantly different ways. Disregarding Brentano's distinctive psychological method, analytic philosophers have typically read him as a philosopher of mind, and his intentionality thesis as a contribution to the Cartesian project of clarifying the distinction between the mental and the physical. Phenomenologists, while more attentive to his method, tended to read Brentano as merely Òon the wayÓ to a truly phenomenological approach. (...) I offer a third reading of Brentano thesis, one that attends to both the motivating concerns and the distinctive methodological features of his psychological project. (shrink)

Nativists about syntactic processing have argued that linguisticprocessing, understood as the implementation of a rule-basedcomputational architecture, is spared in Williams syndrome, (WMS)subjects – and hence that it provides evidence for a geneticallyspecified language module. This argument is bolstered by treatingSpecific Language Impairments (SLI) and WMS as a developmental doubledissociation which identifies a syntax module. Neuroconstructivists haveargued that the cognitive deficits of a developmental disorder cannot beadequately distinguished using the standard gross behavioural tests ofneuropsychology and that the linguistic abilities of the (...) WMS subject canbe equally well explained by a constructivist strategy of neurallearning in the individual, with linguisitic functions implemented in anassociationist architecture. The neuroconstructivist interpretation ofWMS undermines the hypothesis of a double dissociation between SLI andWMS, leaving unresolved the question of nativism about syntax. Theapparent linguistic virtuosity of WMS subjects is an artefact ofenhanced phonological processing, a fact which is easier to demonstratevia the associationist computational model embraced byneuroconstructivism.

A cohesive overview of the philosophy of Heraclitus.

Introspection admits of several varieties, depending on which types of mental events are introspected. I distinguish three kinds of introspection (primary, secondary, and tertiary) and three explanations of the general capacity: the inside access view, the outside access view, and the hybrid view. Drawing on recent evidence from clinical and developmental psychology, I argue that the inside view offers the most promising account of primary and secondary introspection.

Opponents of Humean skepticism about practical reason do not normally exploit his idea that beliefs can only serve the aims we have. Many have used that idea to argue in favour of Humean skepticism. Others have denied that it supports Humean skepticism. I argue that we need to use this idea. It is only by embracing the so-called Humean Theory of Motivation that we can truly see where Hume went wrong.

This provocative study argues that the 'believers' church' should draw on Catholic, Reformed, and Lutheran thought to find a solid basis for Christian political action. The book believes that a 'believers' church' ethic has points of continuity with the quest for social justice in the larger society. Rather than separating discipleship from political life or uncritically baptizing political projects, the believers' church may appeal to natural law as a basis for cooperation with others toward the end of a more just (...) society. The volume draws upon various historical theologians and a variety of contemporary figures to affirm a God-given moral capacity in humans that makes a tolerably just political order possible.

The Nature of Concepts examines a central issue for all the main disciplines in cognitive science: how the human mind creates and passes on to other human minds a concept. An excellent cross-disciplinary collection with contributors including Steven Pinker, Andy Clarke and Henry Plotkin.

Grace and Freedom in a Secular Age offers a concise exposition of key ideas - contingency, otherness, freedom, vulnerability and mutuality - that inform the work of the Canadian philosopher Charles Taylor, especially concerning the dynamics of religious belief and religious denial in what he calls a "a secular age." The book integrates discussion of Immanuel Kant and Susan Neiman in particular and seeks to show how Taylor's work can be fruitfully engaged by theologians.

This book examines the U.S economy from 1967 to 2011 and utilizes a new method to predict the future of the economy as far ahead as 2030. Projections using estimates from the U.S. Bureau of Census are used to further project personal income, personal income annual change, and disposable personal income to 2030.
