A critical examination of Descartes’s Passions of the Soul and Discourse on Method reveals that indeterminate judgments (judgments that do not involve certainty) play a fundamental role in the Cartesian corpus. The following paper establishes this claim and argues that such an analysis provides an avenue for understanding the relationship that Descartes envisions between his Discourse and its readers as well as for understanding his attempts to establish his new science. Finally, it argues that Descartes’s provocative claim in the Passions (...) that generous souls are “naturally led to do great deeds” reveals an heroic and Aristotelian element not only in the Passions but also in Descartes’s own actions.

Thomas Lennon’s book is an important contribution to Descartes scholarship in that it systematically challenges the standard interpretation of the Meditations, i.e., that Descartes sought to refute skepticism and failed, arguing instead that a notion of intellectual integrity rests at the root of Descartes’s thought. All the while, these aims are accomplished through an analysis of the Censura philosophiae cartesianae by Pierre-Daniel Huet, a skeptic and fierce critic of Descartes.Beyond introducing Huet and his relationship to Cartesians like Pierre-Sylvain Regis and (...) Nicolas Malebranche, chapter one argues that Descartes’s apparent pride, arrogance, and vanity precipitated Huet’s conversion from supporter to avid critic of Descartes. Chapters two though seven further establish Huet’s concern with Descartes’s pride. But Lennon’s deeper aim, after arguing that the standard interpretation is a relatively late invention solidified by Richard Popkin’s The History of Scepticism, is systematically to unravel the standard interpretation by addressing the cogito, doubt, the criterion of truth, circularity, God, etc. In each.

The Metaphysics of Knowledge presents the thesis that knowledge is an absolutely fundamental relation, with an indispensable role to play in metaphysics, philosophical logic, and philosophy of mind and language. Knowledge has been generally assumed to be a propositional attitude like belief. But Keith Hossack argues that knowledge is not a relation to a content; rather, it a relation to a fact. This point of view allows us to explain many of the concepts of philosophical logic in terms of (...) knowledge. Hossack provides a theory of facts as structured combinations of particulars and universals, and presents a theory of content as the property of a mental act that determines its value for getting knowledge. He also defends a theory of representation in which the conceptual structure of a content is taken to picture the fact it represents. This permits definitions to be given of reference, truth, and necessity in terms of knowledge. Turning to the metaphysics of mind and language, Hossack argues that a conscious state is one that is identical with knowledge of its own occurrence. This allows us to characterize subjectivity, and, by illuminating the "I"-concept, allows us to gain a better understanding of the concept of a person. Language is then explained in terms of knowledge, as a device used by a community of persons for exchanging knowledge by testimony. The Metaphysics of Knowledge concludes that knowledge is too fundamental to be constituted by something else, such as one's functional or physical state; other things may cause knowledge, but do not constitute it.

Variations in colour perception have featured prominently in recent attempts to argue against the view that colours are objective mind-independent properties of the perceptual environment. My aim in this paper is to defend the view that colours are mind-independent properties in response to worries arising from one type of empirically documented case of perceptual variation: variation in the perception of the «unique hues». §1 sets out the challenge raised by variation in the perception of the unique hues. I argue in (...) §2 that the empirical findings are less dramatic than they might initially appear, and in §3 that accounting for the inter-personal differences is consistent with the view that colours are mind-independent properties that normal subjects veridically perceive, at least roughly speaking.

This book examines the politics of diversity, and explores potential sources of support for an inclusive solidarity, in particular political sources of solidarity.

We discuss external and internal graphical and linguistic representational systems. We argue that a cognitive theory of peoples' reasoning performance must account for (a) the logical equivalence of inferences expressed in graphical and linguistic form, and (b) the implementational differences that affect facility of inference. Our theory proposes that graphical representation limit abstraction and thereby aid “processibility”. We discuss the ideas of specificity and abstraction, and their cognitive relevance. Empirical support both comes from tasks which involve the manipulation of external (...) graphics and tasks that do not. For the former, we take Euler's (1772) circles, provide a novel computational reconstruction, show how it captures abstractions, and contrast it with earlier construals and with Johnson‐Laird's (1983) mental models representations. We demonstrate equivalence of the graphical Euler system, and the nongraphical mental models system. For tasks not involving manipulation of external graphics, we discuss text comprehension, and the mental performance of syllogisms. By positing an internal system with the same specificity as Euler's circles, we cover the mental models data, and generate new empirical predictions. Finally, we consider how the architecture of working memory explains why such specific representations are relatively easy to store. (shrink)

Interpretation is the process whereby a hearer reasons to an interpretation of a speaker's discourse. The hearer normally adopts a credulous attitude to the discourse, at least for the purposes of interpreting it. That is to say the hearer tries to accommodate the truth of all the speaker's utterances in deriving an intended model. We present a nonmonotonic logical model of this process which defines unique minimal preferred models and efficiently simulates a kind of closed-world reasoning of particular interest for (...) human cognition. Byrne's “suppression” data (Byrne, 1989) are used to illustrate how variants on this logic can capture and motivate subtly different interpretative stances which different subjects adopt, thus indicating where more fine-grained empirical data are required to understand what subjects are doing in this task. We then show that this logical competence model can be implemented in spreading activation network models. A one pass process interprets the textual input by constructing a network which then computes minimal preferred models for (3-valued) valuations of the set of propositions of the text. The neural implementation distinguishes easy forward reasoning from more complex backward reasoning in a way that may be useful in explaining directionality in human reasoning. (shrink)

Memory sometimes yields knowledge and sometimes does not. It is, however, natural to suppose that i f a man remembers that p, then he knows that p and formerly knew that p. Remembering something is plausibly construed as a f o rm of knowing something which one has not forgotten and which one knew previously. We argue, to the contrary, that this thesis is false. We present four counterexamples to the thesis that support a different analysis of remembering. We propose (...) that a person remembers that p (at t) if and only if the thought or conviction that p comes from memory (at t) when, in fact, it is true that p. (shrink)

Rubin and Pearl offered approaches to causal effect estimation and Lewis and Pearl offered theories of counterfactual conditionals. Arguments offered by Pearl and his collaborators support a weak form of equivalence such that notation from the rival theory can be re-purposed to express Pearl’s theory in a way that is equivalent to Pearl’s theory expressed in its native notation. Nonetheless, the many fundamental differences between the theories rule out any stronger form of equivalence. A renewed emphasis on comparative research can (...) help to guide applications, further develop each theory, and better understand their relative strengths and weaknesses. (shrink)

Externalism holds, and internalism denies, that the individuation of many of an individual's mental states (e.g., thoughts about the physical world) depends necessarily on relations that individual bears to the physical and/or social environment. Many philosophers, externalists and internalists alike, believe that introspection yields knowledge of the contents of our thoughts that is direct and authoritative. It is not obvious, however, that the metaphysical claims of externalism are compatible with this epistemological thesis. Some (e.g., Burge, 1988; Falvey and Owens (F&O), (...) 1994) have sought to dispel the worry that there is a conflict, though they admit that if such a conflict exists, it spells trouble for externalism (see, e.g., F&O, 1994, p. 108). Boghossian has argued that there is indeed a conflict between externalism and introspective knowledge of content. Surprisingly, however, he also argues that there is a conflict between internalism and introspective knowledge of content. I will defend Boghossian's claim that there is a conflict between externalism and knowledge of content, but criticize his claim that there is a conflict between internalism and knowledge of content.

Executive function has become an important concept in explanations of psychiatric disorders, but we currently lack comprehensive models of normal executive function and of its malfunctions. Here we illustrate how defeasible logical analysis can aid progress in this area. We illustrate using autism and attention deficit hyperactivity disorder (ADHD) as example disorders, and show how logical analysis reveals commonalities between linguistic and non-linguistic behaviours within each disorder, and how contrasting sub-components of executive function are involved across disorders. This analysis reveals (...) how logical analysis is as applicable to fast, automatic and unconscious reasoning as it is to slow deliberate cogitation. (shrink)

A successful lexicographic semantic description characterizes the concepts that occur in establishing the meaning of a listeme by modelling what the competent native-like speaker of the language knows. Because concepts can only be identified to another human through the medium of a natural language, the metalanguage used in the semantic definition of a natural language expression in the object language will always be equivalent to the natural language expression through which that metalanguage is interpreted. The metalanguage of a semantic theory (...) is a demonstrably rational abstract model developed by applying the analyst’s experience and intuitions to inferences drawn from occurrences of actual speech events. Each sense of a listeme is characterized by a description of the salient properties of its typical denotatum. To most effectively implement this project in conceptual engineering is to capture every possible sense of the listeme using metalanguage that is at the same time precise, comprehensive, and succinct. A review of several proposed lexicon/dictionary entries for the listeme cup reveals lacunae that are rectified in a decision procedure whose output characterizes the relevant sense of the input listeme using natural language and the procedural constructs/commands &, XOR, IF, ELSE, ELIF, GOTO, OUTPUT, TENABLE, NEXT ITEM. The resulting lexicographic semantic description satisfies the specified success condition. Establishing the characteristics of metalanguage is crucial to the proper investigation of conceptual engineering. (shrink)

This chapter examines the debates concerning the theory of ideas in Great Britain during the seventeenth century, focusing on the concept, origin, and types of ideas. It explains that the so-called way of ideas that are primarily associated with Rene Descartes and John Locke represent attempts to replace scholastic Aristotelian theories of the nature of the mind and its relation to the world. The chapter also discusses the relevant works of Thomas Hobbes and the Cambridge Platonists, and considers the relevance (...) of skepticism and idealism to the notion of ideas. (shrink)

Why History? is a compelling introduction to the issue of history and ethics. Designed to provoke discussion, the book asks whether and why a good knowledge and understanding of the past is desirable. In the context of current postmodern thinking, Keith Jenkins suggests that the goal of "learning lessons from the past" actually means learning lessons from stories written by historians and others. If the past as history has no foundation, can anything ethical be gained from history? Daring and (...) controversial, Why History? presents liberating challenges to history and ethics, proposing that we have reached an emancipatory moment which is well beyond the "end of history.".

According to regulatory fit theory (Higgins, 2000), when people make decisions with strategies that sustain their regulatory focus orientation, they “feel right” about what they are doing, and this “feeling-right” experience then transfers to subsequent choices, decisions, and evaluations. The present research was designed to link the concept of regulatory fit to functional accounts of counterfactual thinking. In the present study, participants generated counterfactuals about their anagram performance, after which persistence on a second set of anagrams was measured. Under promotion (...) framing (i.e., find 90% or more of all the possible words) upward counterfactual thinking in general elicited larger increases in persistence than did downward counterfactual thinking in general, but under prevention framing (i.e., avoid failing to find 90% or more of all the possible words) upward evaluation (comparing reality to a better reality) elicited larger increases in persistence than did upward reflection (focusing on a better reality), whereas downward reflection (focusing on a worse reality) elicited larger increases in persistence than did downward evaluation (comparing reality to a worse reality). In all, the present findings suggest that the generation of counterfactuals enhances the likelihood that individuals will engage in courses of action that fit with their regulatory focus orientation.

Review of Larry Arnhart, ‘Darwinian Natural Right: The Biological Ethics of Human Nature’, plus response from Larry Arnhart.

This reply to Oaksford and Chater’s ’s critical discussion of our use of logic programming to model and predict patterns of conditional reasoning will frame the dispute in terms of the semantics of the conditional. We begin by outlining some common features of LP and probabilistic conditionals in knowledge-rich reasoning over long-term memory knowledge bases. For both, context determines causal strength; there are inferences from the absence of certain evidence; and both have analogues of the Ramsey test. Some current work (...) shows how a combination of counting defeaters and statistics from network monitoring can provide the information for graded responses from LP reasoning. With this much introduction, we then respond to O&C’s specific criticisms and misunderstandings. (shrink)

In this chapter, we explore how themes of existential philosophy have been used to develop a formal orientation of psychotherapy, and we discuss the main principles of existential psychotherapy and their application in practice. We also draw upon case examples to specifically illustrate how the approach of existential psychotherapy is utilized in clinical practice. In the case examples, each patient's identify has been disguised to maintain confidentiality. The new science of meaning, represented by the chapters in this volume, not only (...) offers therapists a deep conceptual framework within which to practice older, more established techniques but should also suggest new approaches. By recognizing the centrality of meaning as sense making and acknowledging the distinction between the what and the why of sense making, therapists should be armed with a variety of epistemic and teleological tools with which to fashion therapy strategies that are unique for each individual.

The vision of global health with justice which Larry Gostin articulates in his book Global Health Law envisages a switch to ‘upstream’ priority-setting for expenditure on health, with a focus upon social determinants and a goal of redressing health inequalities. This article explores what is meant by this proposal and offers a critical evaluation of it. It is argued that difficulties arise in respect of the ethical and evidential bases for such an approach to the setting of priorities, while significant (...) challenges may also arise in the necessary modification of structures of governance.
