In solving judgment aggregation problems, groups often face constraints. Many decision problems can be modelled in terms the acceptance or rejection of certain propositions in a language, and constraints as propositions that the decisions should be consistent with. For example, court judgments in breach-of-contract cases should be consistent with the constraint that action and obligation are necessary and sufficient for liability; judgments on how to rank several options in an order of preference with the constraint of transitivity; and judgments on (...) budget items with budgetary constraints. Often more or less demanding constraints on decisions are imaginable. For instance, in preference ranking problems, the transitivity constraint is often contrasted with the weaker acyclicity constraint. In this paper, we make constraints explicit in judgment aggregation by relativizing the rationality conditions of consistency and deductive closure to a constraint set, whose variation yields more or less strong notions of rationality. We review several general results on judgment aggregation in light of such constraints. (shrink)

Agents are often assumed to have degrees of belief (“credences”) and also binary beliefs (“beliefs simpliciter”). How are these related to each other? A much-discussed answer asserts that it is rational to believe a proposition if and only if one has a high enough degree of belief in it. But this answer runs into the “lottery paradox”: the set of believed propositions may violate the key rationality conditions of consistency and deductive closure. In earlier work, we showed that this problem (...) generalizes: there exists no local function from degrees of belief to binary beliefs that satisfies some minimal conditions of rationality and non-triviality. “Locality” means that the binary belief in each proposition depends only on the degree of belief in that proposition, not on the degrees of belief in others. One might think that the impossibility can be avoided by dropping the assumption that binary beliefs are a function of degrees of belief. We prove that, even if we drop the “functionality” restriction, there still exists no local relation between degrees of belief and binary beliefs that satisfies some minimal conditions. Thus functionality is not the source of the impossibility; its source is the condition of locality. If there is any non-trivial relation between degrees of belief and binary beliefs at all, it must be a “holistic” one. We explore several concrete forms this “holistic” relation could take. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy of Music Education Review 13.2 (2005) 142-145 [Access article in PDF] The Doing of Philosophy in the Music Class: Some Practical Considerations. Response to Bennett Reimer Mary J. Reichling University of Louisiana at Lafayette How I respond to Bennett Reimer's challenge depends in part on how we define philosophy in this context. We might think of philosophy as a subject of study, that is, philosophy in itself (...) such as epistemology, metaphysics, and so on. Or we may conceive it as philosophy of music, better designated as aesthetics. Or we may consider philosophy as a verb in the sense of "doing" philosophy where our goal is to assist students in developing their thinking skills. It seems that Reimer is placing focus on the last, the doing of philosophy, not that these other views of philosophy are mutually exclusive; they are not.Yet even this distinction is not sufficient for discussion. I am reminded of a little book edited by Eunice Boardman, titled Dimensions of Musical Thinking and published by MENC in 1989. It is a real gem with many fine ideas. In particular it stresses the relationship of content-area knowledge to thinking, and that is what I want to do. Developing thinking skills does not take place in a vacuum: "Now I am going to think." It occurs with respect to a subject area. We have philosophy of science, philosophy of history, philosophy of art, and so on, and philosophy of music.Further, our thinking about music occurs in at least two different ways. I suggest that music possesses both instrumental and intrinsic value with respect to philosophical analysis, as well as instances where the two values are combined. In pondering these values we bring together several so-called philosophical 'methodologies': the search for meaning or understanding, analysis, criticism, [End Page 142] and synthesis. In the process we build arguments that are consistent, coherent, and correspond with the musical evidence.1And further, in our field, students, whether it be through course content itself or through performance classes, have the advantage of gaining both propositional knowledge, learning that, for example, the rhythmic value of eighth notes, and procedural knowledge or learning how, for example, performing eighth notes vocally or instrumentally.2Both of which challenge the students' thinking skills.It is also important to articulate several assumptions if we aspire to "doing" philosophy within the teaching of music. These include a belief that it is worthwhile to develop such thinking skills as I have outlined; that we are willing to take the time for dialogue within the music class or rehearsal hour; and that we as teachers are willing to be facilitators of questions rather than experts with answers.I shall attempt with a few examples to show how these thinking processes might be integrated into the music curriculum following Jerome Brunner's view that children can be taught anything if done so at their level of understanding.The first example relates to the instrumental value of music as it supports text or programmatic conceptions. Let us consider the text of a particular song such as "Blowing in the Wind" or the "Kookaburra" song, the subject of an opera such as Berg's Wozzeck, or the topic of war as exemplified in Britten's War Requiem or some of the protest songs. We ask students how the extra musical subjects are established musically, how the music communicates the ideas, why one musical setting is preferred or better than another, and so forth. In dialoging about these examples, students must first of all be perceptive listeners or participants, then analyze at their level of ability. For an elementary child such analysis might be as simple as pointing out the tempo, mood, rhythms, dynamics, or other expressive elements. Advanced students will have a more extensive musical background to draw upon. Through the analysis students come to a synthesis of these factors that leads to greater understanding of the meaning of the music as they approach questions of value and beauty. If the teacher...

In lieu of an abstract, here is a brief excerpt of the content:Philosophy of Music Education Review 12.1 (2004) 17-29 [Access article in PDF] Intersections Form, Feeling, and Isomorphism Mary J. Reichling University of Louisiana at Lafayette These three concepts hold meanings that differ among musicians and aestheticians. In this essay I shall explore them in the writings of Susanne Langer. Contemporary musicians and aestheticians continue today to engage Langer albeit some favorably and others with disdain. Whatever their reasons, (...) she remains a dominant force in the philosophy of music.1 My purpose is not to defend her against her detractors, but rather to examine and to elucidate various aspects of these three concepts in her writing, as they are fundamental to an understanding of her aesthetic theory and to the construction of a philosophy of music and music education.First, I consider the broad and complex notion of form and the various ways Langer employs it in her aesthetic theory. Next, the rather all-encompassing idea of feeling as Langer conceives it is studied in relation to the form of the musical work. The intersection of form and feeling in the concept of isomorphism concludes the discussion. [End Page 17] Form In her various writings Langer uses several adjectives associated with the word "form" which seem to organize well into three groups. The first concerns the dynamic, living, organic, and vital qualities of form; the second speaks to its logical and abstract nature; and the last relates to the emotional or feeling aspect of form including expressive and significant characteristics.2 These groupings overlap and intertwine, but focusing on each specifically rather than all as a totality offers important insights.Form as dynamic, living, organic, and vital suggests metaphorical reference. Obviously the form is not physically, biologically, alive; reference is to the apparent movement, growth, and aliveness of the musical form as it is heard or performed. Thus this idea of form implies an actual performance to be realized or perceived. Langer is sometimes criticized for giving little attention to the actual making of music, that is, performance, yet her theory assumes music as heard. Essential to perceiving a dynamic form or hearing a feeling is a processual event, namely, performance or listening to a performance. Rarely a professional musician or gifted amateur might be able to engage this concept of form by reading through a score and hearing the music in imagination.Dynamic form parallels Eduard Hanslick's notion of tonend bewegte Formen. One might object that Hanslick and Langer are in conflict as Hanslick opposes while Langer supports the conviction that form is expressive of feeling, but that is moving beyond the matter at hand and suggests a superficial reading of both Hanslick and Langer. Hanslick asserts emphatically that music's meaning is not the arousal of emotion but does not deny feeling in music; Langer holds the same view. But Hanslick allows that "the words content and form are used not in the purely logical, but in an artistic sense." To me this suggests that he recognizes a nonliteral or metaphorical interpretation. He writes about the relationship of musical tones as "fraught with significance... congruity and opposition, their separating and combining, their soaring and subsiding-this is what comes in spontaneous forms before our inner contemplation and pleases us as beautiful." Certainly this parallels Langer's description of dynamic form.3 What is significant is that both philosophers are addressing the fluid, processual, active, movement-of-notes-through-time nature of musical form.The premise that forms are created by motion, are dynamic, is easily grasped by offering some examples. Fast cameras are able to take a series of photos of the movements of a pianist's hands giving still pictures of the moving forms created while performing a given passage.4 Alternately, forms are created by the movements of clouds or fog through the mist and early light; they are, in effect, quite literally moving forms. Cartoon characters generate moving forms through the [End Page 18] use of many drawings or more recently by means of computer animation. Time is a dynamic or moving form which we divide into hours...

The Christian does not live in a vacuum, says the author, but in a world of government, politics, labor, and marriage. Hence, Christian ethics cannot exist in a vacuum what the Christian needs, claims Dietrich Bonhoeffer, is concrete instruction in a concrete situation. Although the author died before completing his work, this book is recognized as a major contribution to Christian ethics. The root and ground of Christian ethics, the author says, is the reality of God as revealed in (...) Jesus Christ. This reality is not manifest in the Church as distinct from the secular world such a juxtaposition of two separate spheres, Bonhoeffer insists, is a denial of God's having reconciled the whole world to himself in Christ. On the contrary, God's commandment is to be found and known in the Church, the family, labor, and government. His commandment permits man to live as man before God, in a world God made, with responsibility for the institutions of that world. (shrink)

The E-Z Reader model (Reichle et al. 1998; 1999) provides a theoretical framework for understanding how word identification, visual processing, attention, and oculomotor control jointly determine when and where the eyes move during reading. In this article, we first review what is known about eye movements during reading. Then we provide an updated version of the model (E-Z Reader 7) and describe how it accounts for basic findings about eye movement control in reading. We then review several alternative models of (...) eye movement control in reading, discussing both their core assumptions and their theoretical scope. On the basis of this discussion, we conclude that E-Z Reader provides the most comprehensive account of eye movement control during reading. Finally, we provide a brief overview of what is known about the neural systems that support the various components of reading, and suggest how the cognitive constructs of our model might map onto this neural architecture. Key Words: attention; eye-movement control; E-Z Reader; fixations; lexical access; models; reading; regressions; saccades. (shrink)

There is a prevalent notion among cognitive scientists and philosophers of mind that computers are merely formal symbol manipulators, performing the actions they do solely on the basis of the syntactic properties of the symbols they manipulate. This view of computers has allowed some philosophers to divorce semantics from computational explanations. Semantic content, then, becomes something one adds to computational explanations to get psychological explanations. Other philosophers, such as Stephen Stich, have taken a stronger view, advocating doing away with semantics (...) entirely. This paper argues that a correct account of computation requires us to attribute content to computational processes in order to explain which functions are being computed. This entails that computational psychology must countenance mental representations. Since anti-semantic positions are incompatible with computational psychology thus construed, they ought to be rejected. Lastly, I argue that in an important sense, computers are not formal symbol manipulators. (shrink)

The widely discussed "discursive dilemma" shows that majority voting in a group of individuals on logically connected propositions may produce irrational collective judgments. We generalize majority voting by considering quota rules, which accept each proposition if and only if the number of individuals accepting it exceeds a given threshold, where different thresholds may be used for different propositions. After characterizing quota rules, we prove necessary and sufficient conditions on the required thresholds for various collective rationality requirements. We also consider sequential (...) quota rules, which ensure collective rationality by adjudicating propositions sequentially and letting earlier judgments constrain later ones. Sequential rules may be path-dependent and strategically manipulable. We characterize path-independence and prove its essential equivalence to strategy-proofness. Our results shed light on the rationality of simple-, super-, and sub-majoritarian decision-making. (shrink)

Behaviourism is the view that preferences, beliefs, and other mental states in social-scientific theories are nothing but constructs re-describing people's behaviour. Mentalism is the view that they capture real phenomena, on a par with the unobservables in science, such as electrons and electromagnetic fields. While behaviourism has gone out of fashion in psychology, it remains influential in economics, especially in ‘revealed preference’ theory. We defend mentalism in economics, construed as a positive science, and show that it fits best scientific practice. (...) We distinguish mentalism from, and reject, the radical neuroeconomic view that behaviour should be explained in terms of brain processes, as distinct from mental states. (shrink)

In the theory of judgment aggregation, it is known for which agendas of propositions it is possible to aggregate individual judgments into collective ones in accordance with the Arrow-inspired requirements of universal domain, collective rationality, unanimity preservation, non-dictatorship and propositionwise independence. But it is only partially known (e.g., only in the monotonic case) for which agendas it is possible to respect additional requirements, notably non-oligarchy, anonymity, no individual veto power, or implication preservation. We fully characterize the agendas for which there (...) are such possibilities, thereby answering the most salient open questions about propositionwise judgment aggregation. Our results build on earlier results by Nehring and Puppe (2002), Nehring (2006), Dietrich and List (2007a) and Dokow and Holzman (2010a). (shrink)

There are many possible ways to approach the topic of educational theory and critique. One could inquire into the meaning of critical phenomena and subject-matter in practical education and instruction, investigate the various forms of critique with the goal of determining the extent to which they assist in clarifying pedagogical action, or one could ask: ‘What is meant by critical educational research?’ and ‘How do the various approaches to this topic relate to one another?’. This article inquires into the relationship (...) between critique and negativity. Such a distinction is relevant for the practical, theoretical and research-oriented use of the various forms and subject matters of critique. This analysis of their relationship aims to clarify how the structure of human learning connects to that of pedagogical action; and, additionally, how the theoretical guidelines and orientation for pedagogical action relate to scientific analyses and research in education in a way that is productive. Distinctions made in thought, judgement and action are not simply delimiting positive characteristics. Such distinctions are at once mediated by the relations of knowledge and ignorance, ability and inability. Although ignorance and inability can be transformed into positive knowledge and ability, they are not superseded in the process. Ignorance and inability are, on the contrary, constitutive elements of learning. The possibility for transitions from ignorance and inability to knowledge and ability—a possibility that itself presupposes knowledge and ability—point to a form of negativity within the process of education (Bildung). This form of negativity relates to the human ability to learn (Bildsamkeit) and provides the definitive basis of human learning. A form of negativity constitutive of learning processes leads to one that grounds pedagogical processes. Pedagogical efficacy is mediated by a double negativity, comprised of both a universal and a particular form of negativity. The relation of negativity to learning and pedagogical efficacy, with specific reference to educational research studies on teaching and learning processes, is considered. A form of educational research that operates beyond fundamentalist criticisms—that is to say, criticisms based on unshakeable beliefs—and utilises issues arising from a pluralisation of critique to confront the pluralism of critical positions, is considered. The article closes with reflections on the relation between the Critical and the Uncritical. (shrink)

An important question about eye-movement behavior is when the decision is made to terminate a fixation and program the following saccade. Different approaches have found converging evidence in favor of a mixed-control account, in which there is some overlap between processing information at fixation and planning the following saccade. We examined one interesting instance of mixed control in visual search: lag-2 revisits, during which observers fixate a stimulus, move to a different stimulus, and then revisit the first stimulus on the (...) next fixation. Results show that the probability of lag-2 revisits occurring increased with the number of target-similar stimuli, and revisits were preceded by a brief fixation on the intervening distractor stimulus. We developed the Efficient Visual Sampling computational model to simulate our findings and to provide insight into mixed control of fixations and the perceptual, cognitive, and motor processes that produce lag-2 revisits.

We introduce a “reason-based” framework for explaining and predicting individual choices. It captures the idea that a decision-maker focuses on some but not all properties of the options and chooses an option whose motivationally salient properties he/she most prefers. Reason-based explanations allow us to distinguish between two kinds of context-dependent choice: the motivationally salient properties may (i) vary across choice contexts, and (ii) include not only “intrinsic” properties of the options, but also “context-related” properties. Our framework can accommodate boundedly rational (...) and sophisticatedly rational choice. Since properties can be recombined in new ways, it also offers resources for predicting choices in unobserved contexts. (shrink)

All existing impossibility theorems on judgment aggregation require individual and collective judgment sets to be consistent and complete, arguably a demanding rationality requirement. They do not carry over to aggregation functions mapping profiles of consistent individual judgment sets to consistent collective ones. We prove that, whenever the agenda of propositions under consideration exhibits mild interconnections, any such aggregation function that is "neutral" between the acceptance and rejection of each proposition is dictatorial. We relate this theorem to the literature.

Which rules for aggregating judgments on logically connected propositions are manipulable and which not? In this paper, we introduce a preference-free concept of non-manipulability and contrast it with a preference-theoretic concept of strategy-proofness. We characterize all non-manipulable and all strategy-proof judgment aggregation rules and prove an impossibility theorem similar to the Gibbard--Satterthwaite theorem. We also discuss weaker forms of non-manipulability and strategy-proofness. Comparing two frequently discussed aggregation rules, we show that “conclusion-based voting” is less vulnerable to manipulation than “premise-based voting”, (...) which is strategy-proof only for “reason-oriented” individuals. Surprisingly, for “outcome-oriented” individuals, the two rules are strategically equivalent, generating identical judgments in equilibrium. Our results introduce game-theoretic considerations into judgment aggregation and have implications for debates on deliberative democracy. (shrink)

Recently, a number of philosophers of biology have endorsed views about random drift that, we will argue, rest on an implicit assumption that the meaning of concepts such as drift can be understood through an examination of the mathematical models in which drift appears. They also seem to implicitly assume that ontological questions about the causality of terms appearing in the models can be gleaned from the models alone. We will question these general assumptions by showing how the same equation (...) — the simple 2 = p2 + 2pq + q2 — can be given radically different interpretations, one of which is a physical, causal process and one of which is not. This shows that mathematical models on their own yield neither interpretations nor ontological conclusions. Instead, we argue that these issues can only be resolved by considering the phenomena that the models were originally designed to represent and the phenomena to which the models are currently applied. When one does take those factors into account, starting with the motivation for Sewall Wright’s and R.A. Fisher’s early drift models and ending with contemporary applications, a very different picture of the concept of drift emerges. On this view, drift is a term for a set of physical processes, namely, indiscriminate sampling processes. (shrink)

In 2006, mountaineer David Sharp died on the slopes of Mount Everest. Sharp’s death led to public outrage after allegedly 40 climbers passed by the dying Sharp on their way to the peak, without stopping to help. But, since the slopes of Everest are a high-risk environment and rescuing Sharp would have entailed great risks for the rescuers, it is not clear whether the other mountaineers had a moral duty to rescue him. In a recent article, Patrick Findler introduces a (...) principle to analyse such cases which states that we have a duty to rescue under dangerous circumstances, if the involved risks are not higher than the risks we are already taking in the pursuit of our own, morally less worthy ends. However, Findler then rejects this principle as too demanding. In this paper I will defend the principle against its inventor and argue in favour of such a duty. And while it may be true that the other mountaineers were justified in passing Sharp for different reasons, the principle shows that not only climbers, but adventure-sport athletes in general and people who engage in high-risk endeavours, may have a duty to rescue that doesn’t apply to others.

I argue that while Fichte is able to resolve the tension between Herder’s pluralism and Kant’s chiliasm in an (...) innovative manner, the deployment of his first principle is ultimately unsuccessful in establishing historiography on a firmer scientific foundation.

Musica Poetica provides an unprecedented examination of the development of Baroque musical thought. The initial chapters, which serve as an introduction to the concept and teachings of musical-rhetorical figures, explore Martin Luther's theology of music, the development of the Baroque concept of musica poetica, the idea of the affections in German Baroque music, and that music's use of the principles and devices of rhetoric. Dietrich Bartel then turns to more detailed considerations of the musical-rhetorical figures that were developed in (...) Baroque treatises and publications. After brief biographical sketches of the major theorists, Bartel examines those theorists' interpretation and classification of the figures. The book concludes with a detailed presentation of the musical-rhetorical figures, in which each theorist's definitions are presented in the original language and in parallel English translations. Bartel's clear, detailed analysis of German Baroque musical-rhetorical figures, combined with his careful translations of interpretations of those figures from a wide range of sources, make this book an indispensable introduction and resource for all students of Baroque music. Dietrich Bartel is an associate professor in the Department of Music at Canadian Mennonite Bible College (affiliated with University of Manitoba). (shrink)

Despite relative neglect in the literature, Kant’s published and unpublished writings in theoretical philosophy reveal a sustained and at times ambivalent effort to come to terms with the problem of miracles.

I explore in detail Kant’s account of miracles in conjunction with the relevant aspects of his metaphysics of nature in order to establish in what (...) sense miracles are possible, and how they fit into Kant’s architectonic more generally.
