To date, little is known about when and to what degree science students begin to participate in authentic scientific graphing practices. This article presents the results of a series of studies on the production, transformation, and interpretation of graphical representation from Grade 8 to professional scientific practice both in formal testing situations and in the course of field/laboratory work. The results of these studies can be grouped into two major areas. First, there is a discontinuity in the graph-related practices that (...) marks a boundary between people who engage in work that requires them to transform data into graphical representations and people who do not have such experiences. Second, the didactic practices of high school textbooks and university lectures exhibit a marked discontinuity relative to graphing practices in scientific journals. Graphs used in didactic circumstances may be associated with students’ difficulties in interpreting “real data.” It appears that school teachers and university professors do little to put their students on trajectories of increasing participation in authentic scientific graphing practices.

Adolescence has been linked to an enhanced tolerance of uncertainty and risky behavior and is possibly connected to an increased response toward rewards. However, previous research has produced inconsistent findings. To investigate whether these findings are due to different reward probabilities used in the experimental design, we extended a monetary incentive delay task by including three different reward probabilities. Using functional magnetic resonance imaging, 25 healthy adolescents and 22 adults were studied during anticipation of rewards in the VS. Differently colored (...) cue stimuli indicated either a monetary or verbal trial and symbolized different reward probabilities, to which the participants were blinded. Results demonstrated faster reaction times for lower reward probabilities in both age groups. Adolescents were slower through all conditions and had less activation on a neural level. Imaging results showed a three-way interaction between age group x condition x reward probability with differences in percent signal change between adolescents and adults for the high reward probabilities while adolescents demonstrated differences for the lowest. Therefore, previous inconsistent findings could be due to different reward probabilities, which makes examining these crucial for a better understanding of adolescent and adult behavior. (shrink)

This study was designed to find out what scientists and science students actually do when they are reading familiar and unfamiliar graphs. This study provides rich details of the subtle changes in the ontologies of scientists and science students as they engage in the reading tasks assigned to them. In the course of the readers’ interpretation work, initially unspecified marks on paper are turned into objects with particular topologies that are said to correspond to specific features in the world. We (...) theorize this interpretive work as a transition of graphs from things to signs that come to stand for natural objects. Especially among physicists and theoretical ecologists, graphs enter new relations and become natural objects in their own right. (shrink)

Signs do not only “represent” something for somebody, as Peirce’s definition goes, but also “mediate” relations between us and our world, including ourselves, as has been elaborated by Vygotsky. We call the first the representational function of a sign and the second the epistemological function since in using signs we make distinctions, specify objects and relations, structure our observations, and organize societal and cognitive activity. The goal of this paper is, on the one hand, to develop a model in which (...) both these functions appear as complementary and, on the other, to show that this complementarity is essential for the dynamics of scientific activity, causing a dialectical process of generating new epistemological and representational means. This will be demonstrated with an example of how two scientists with different background knowledge analyze educational data collaboratively. (shrink)

Radical uncertainty is a concept currently debated, for example, in the economics literature to theorize the impossibility of foreseeing the outcomes of scientific and technological development work. The purpose of this study is to extend the concept to articulate and theorize the minute-to-minute transactions in scientific laboratories. Empirical materials resulting from five years of ethnographic work in one laboratory focusing on fish vision are used to show how scientists produce a material continuity between some natural phenomena and the way they (...) are represented in scientific discourse. Because the outcomes of scientists' actions sometimes turn out to be uncertain, the material actions that produce this continuity themselves retroactively become uncertain. Scientists may at any one point determine that what they had done is not what they thought and said to have done. Actions and the objects they produce therefore stand in a dialectical relationship: they produce, mutually presuppose, and in their respective materiality, stabilize one another. (shrink)

A central challenge for research on how we should prepare students to manage crossing boundaries between different knowledge settings in life long learning processes is to identify those forms of knowledge that are particularly relevant here. In this paper, we develop by philosophical means the concept of a dialectical system as a general framework to describe the de-velopment of knowledge networks that mark the starting point for learning processes, and we use semiotics to discuss the epistemological thesis that any cognitive (...) access to our world of objects is mediated by signs and diagrammatic reasoning and abduction as those forms of practical knowledge that are crucial for the development of knowledge networks. The rich-ness of this theoretical approach becomes evident by applying it to an example of learning in a biological research context. At the same time, we take a new look at the role of mathematical knowledge in this process. (shrink)

Different situations — like school and workplace — demand different forms of knowledge. Even more important, in particular for lifelong learning, are forms of knowledge we need for managing movements between those situations. To develop a better understanding of how to ‘navigate’ knowledge boundaries, this paper analyzes, firstly, interviews with scientists interpreting familiar and unfamiliar graphs. Our goal is to identify those forms of knowledge that should receive special attention in education. Secondly, the article elaborates — based on Peirce’s semiotics (...) — an epistemologically reflected semiotic model to describe the role and conditions of knowledge necessary for crossing knowledge boundaries.

Over 60 years ago, the influential language philosopher L. Wittgenstein suggested that there is no need to use "understanding" and "meaning" to understand how language works and, in fact, that the two theoretical terms are part of a primitive idea. Today, both remain two of the most frequently used terms in education. The purpose of this paper is to stimulate a discussion about abandoning these terms from the theoretical discourse of education in the way these are commonly used. Case materials (...) from the research literature chosen from a large database on knowing and learning in science are used to exemplify the approach that does not require either concept. Implications are drawn for education research and practice. (shrink)

In this article, we propose that gestures play an important role in the connection between sensorimotor experience and language. Gestures may be the link between bodily experience and verbal expression that advocates of embodied cognition have postulated. In a developmental sequence of communicative action, gestures, which are initially similar to action sequences, substantially shorten and represent actions in metonymic form. In another process, action sequences are based on kinesthetic schemata that themselves find their metaphoric expression in language. Again, gestures enact (...) kinesthetic schemata that are correlated with verbal expressions. Examples from a large database are used to illustrate the various processes by means of which language arises when students conduct school science investigations. (shrink)

A science that does not critically interrogate its theoretical concepts literally does not know what it is doing. The attempt to clarify a widely used concept in psychological research—the concept of concept—therefore constitutes an important effort in clarifying what role it plays in the discursive work of the field. In this commentary, I take a cultural-historical approach to suggest that the clarification of concepts requires both a genuine rupture and a historical study of the movement of a concept. Moreover, our (...) study of concepts has to be reflexive because they are simultaneously objects of inquiry and means by which such inquiry unfolds. Rather than doing mere analysis of concept use, I propose a categorical, historical reconstruction of the concepts psychologists use. 2012 APA, all rights reserved). (shrink)

In this study, I describe a potential challenge to semiotics, which exists in the fact that no interpretation of an instruction can get us closer to doing what the instructional text describes.

I discuss the gap between instructions and the behavior they describe and the moral (...) order of praxis that is not inscribed in instructions. (shrink)

Toward the end of his life, the Russian psychologist L.S. Vygotsky turned away from his earlier work that he has become famous for only to sow the seeds for a new theory. In this theory, affect was to play a central role, there was to be a primacy of social relations, and anything mental (mind, thought, self, other, knowledge) was an event rather than a thing. This is essentially a transactional perspective. In this book, the author articulates a transactional psychology (...) of education drawing on the works of G.H. Mead, J. Dewey, G. Bateson, F. Mikhailov, and E. Il'enkov. All theoretical positions are developed out of videotaped exchanges, thereby giving concrete character to every psychological concept articulated. (shrink)

The role of gestures in communication is still debated: Some claim that gestures are merely ancillary forms of expressions, whereas others suggest a central role of gestures in the development of language. In this article, I provide data in support of the overarching hypothesis that gestures have a transitional function between ergotic/epistemic movements of hands and symbolic expressions. The context for the study of these transitions is constituted by school science laboratory activities conducted by students who are also asked to (...) describe and explain while still within proximity of the materials of their investigations. It is hypothesized that communication is distributed across the context (verbal, gestural, material) and shifts increasingly into a verbal modality as students become familiar with the phenomena they are to learn about. Furthermore, it is hypothesized that initial temporal delays between gestures and the corresponding words decrease and finally disappear so that gestural and verbal modalities coincide. It is suggested that engaging in communication in the presence of material has an important cognitive function in that it affords a distribution of cognition across different modalities until individuals have developed the competence to express themselves effectively in the verbal modality.

Research into expertise is relatively common in cognitive science concerning expertise existing across many domains. However, much less research has examined how experts within the same domain assess the performance of their peer experts. We report the results of a modified think-aloud study conducted with 18 pilots . Pairs of same-ranked pilots were asked to rate the performance of a captain flying in a critical pre-recorded simulator scenario. Findings reveal considerable variance within performance categories, differences in the process used as (...) evidence in support of a performance rating, different numbers and types of facts identified, and differences in how specific performance events affect choice of performance category and gravity of performance assessment. Such variance is consistent with low inter-rater reliability. Because raters exhibited good, albeit imprecise, reasons and facts, a fuzzy mathematical model of performance rating was developed. The model provides good agreement with observed variations. (shrink)

Science literacy is frequently touted as a key to good citizenship. Based on a two-year ethnographic study examining science in the community, the authors suggest that when considering the contribution of scientific activity to the greater good, science must be seen as forming a unique hybrid practice, mixed in with other mediating practices, which together constitute “scientifically literate, good citizenship.” This case study, an analysis of an open house event organized by a grassroots environmentalist group, presents some examples of activities (...) that embed science in “good citizenship.” Through a series of vignettes, the authors focus on four central aspects: the activists' use of landscape and spatial arrangements, the importance of multiple representations of the same entity, the relational aspect of knowing and becoming part of a community, and the insertion of scientific into moral discourse, resulting in what they call a “stewardship triad.”.

The theory of knowledge objectification, initially presented and developed by Luis Radford, has gained some traction in the field of mathematics education. As with any developing theory, its presentation contains statements that may contradict its stated intents; and these problems are exacerbated in its uptake into the work of other scholars. The purpose of this study is to articulate a Spinozist-Marxian approach, in which the objectification exists not in things—semiotic means that mediate interactions—but as real relation between people. As a (...) consequence, the concept of mediation is unnecessary and can be abandoned. A concrete classroom example from Radford’s own studies is used to exemplify and develop pertinent issues. In particular, the societal nature of the ideal—a synecdoche of relations between objects that reflect relations between people—should be added and the notion of mediation no longer is required.

Despite its advanced age of about 375 years, the mind–body problem is alive and well, in part because it is anchored so well institutionally in schools and in research. This continued presence is astonishing in the light of the fact that the seed for its solution, sown in Spinoza’s Ethics, is almost as old. The solution rests on the position that there is only one substance, which, invisible, manifests itself in two attributes, thought and extension. By thinking with Spinoza, especially (...) by following the ways in which Vygotsky and Marx think with Spinoza, we arrive at an approach suitable for a social psychological theory of learning that does not separate knowing from doing and emoting. A classroom fragment from a 10th-grade physics curriculum is used as the starting point for overcoming the body–mind problem by thinking with Spinoza. (shrink)

Wolff's book defends the Kantian idea of a "general logic" whose principles underlie special systems of deductive logic. It thus undermines "logical pluralism," which tolerates the co-existence of divergent systems of modern logic without asking for consistent common principles. Part I of Wolff’s book identifies the formal language in which the most general principles of logic must be expressed. This language turns out to be a version of syllogistic language already used by Aristotle. The universal validity of logical (...) principles, as well as the translatability of other logical languages into this language, are shown to depend only on the meanings of its logical vocabulary. Part II of the book answers the metalogical question concerning the deductive relation between general logic and special logical systems, which also have their own (less general) principles. This part identifies the rules according to which logical rules can be derived from principles. The main result of the book is that the highest principles of logic and metalogics are provided by the syllogistic, when properly understood. (shrink)

This article examines Kant′s use of the expression “fact of reason” by giving an analysis of the pseudo-mathematical method which Kant employs in the first part of the Critique of Practical Reason. It turns out that Kant′s use of this expression has nothing to do with appealing to a certain fact as being an obvious, self-evident truth. There is no need for such an appeal since the “Fundamental Law of Pure Practical Reason” is a “practical postulate” which, like a postulate (...) in geometry, is unquestionably certain. In order to realize its validity it is sufficient to know what a practical law is and on what its validity depends. The fundamental law of pure practical reason needs, in Kant′s view, a “deduction” since it is a synthetic principle a priori. But its deduction cannot be a proof since postulates neither can nor need be proved. It has to be a justification which guarantees that the use of pure reason in giving practical laws is not “transcendent”, but “immanent”. This justification has, unlike Kant′s deduction of the “Postulates of Empirical Thinking”, the systematic form of a “defence” which invalidates possible objections by showing that they themselves necessarily rest on a transcendent use of reason.

Using the behavioral agency model, we analyze how two compensation design characteristics, pay-performance sensitivity and duration of CEO compensation, affect corporate social performance. We find that the performance sensitivity of CEO pay is negatively associated with poor social performance but also negatively affects strong social performance. These results suggest that pay-performance sensitivity increases the relevance of potential negative consequences of poor social performance. However, the ‘insurance’ benefits of strong social performance may also become less relevant. With respect to the duration (...) of CEO compensation, we find that it reduces poor social performance. This finding confirms arguments that a long-term compensation time horizon increases the perceived threat that the negative effects of poor social performance will become visible. With our findings, we integrate behavioral agency theory with the traditional stakeholder views. (shrink)

Here I attempt to clarify the general sense of the question that forms the background of Hegel's section on contradiction: What is the essence of contradiction?

Kant's theory of space includes the idea that straight lines and planes can be defined in Euclidean geometry by a concept which nowadays has been revived in the field of fractal geometry: the concept of self-similarity. Absolute self-similarity of straight lines and planes distinguishes Euclidean space from any other geometrical space. Einstein missed this fact in his attempt to refute Kant's theory of space in his article ‘Geometrie und Erfahrung’. Following Hilbert and Schlick he took it for granted, mistakenly, that (...) purely geometrical definitions of the concepts of straight line and plane are not feasible, except as “implicit definitions”. Therefore Einstein's criticism is not persuasive. (shrink)

Although there are many points of continuity, there are also a number of changes in the pedagogical form of the anatomy lecture over the longue durée, over centuries of epistemic change, rather than over years or decades. The article begins with an analysis of the physical and technical arrangements of the early modern anatomy lecture, showing how these present a general underlying similarity compared to those in place today. It then goes on to consider examples of elements of speech and (...) presentation, description and illustration that are used in the biology lecture from the early modern (sixteenth to seventeenth centuries) and late modern (or contemporary) eras. The anatomy lecture thus demonstrates a basic physical and technical continuity in the classroom or theater, whereas the larger epistemic functions in which it is embedded have changed: from a descriptive, discursive function, focusing on individual organs and their physicality, to one that is more integrative, systemic and also performative in both form and content.

The ArgumentOne of the earliest arguments for Copernicanism was a widely accepted fact: that on a horizontal plane a body subject to no external resistance can be set in motion by the smallest of all possible forces. This fact was contrary to Aristotelian physics; but it was a physical argument (by abduction) for the possibility of the Copernican world system. For it would be explained if that system was true or at least possible.Galileo argued: only nonviolent motions can be caused (...) by the smallest of all possible forces; hence resistance-free horizontal motions are nonviolent; this confirms Copernicanism insofar as it designates the rotations of celestial spheres (being resistance-free horizontal motions) as nonviolent.Galileo's argument was compatible with (and supportive of) the specific Copernican version of impetus mechanics; but it was also compatible with a (somewhat qualified) principle of inertia. Thus it promoted decisively the transition from impetus mechanics to classical inertial mechanics. (shrink)

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

The aim of this article is to explain the proofs Aristotle calls proofs "by exposition" and to find out the rules and principles these proofs rest on. The first part shows why previous attempts to explain Aristotle's method of "exposition" have failed. The second part develops a new explanation and reconstructs all of Aristotle's expository proofs on the basis of a few simple rules. The last part shows that the new interpretation of Aristotle's method has very important consequences regarding, firstly, (...) the extent to which Aristotle's logic is valid, secondly, the relationship between syllogistic and geometric exposition and, last but not least, the correct understanding of the principles underlying Aristotle's logical system and the correct understanding of what a "complete" syllogism is. Thus, the article solves a number of fundamental problems concerning the interpretation of Aristotle's syllogistic. (shrink)

In an earlier article (see J Gen Philos Sei (2010) 41: 341-355) I have compared Aristotle's syllogistic with Kant's theory of "pure ratiocination". "Ratiocinia pura" („reine Vernunftschlüsse") is Kant's designation for assertoric syllogisms Aristotle has called 'perfect'. In Kant's view they differ from non-pure ratiocinia precisely in that their validity rests only on the validity of the Dictum de omni et nullo (which, however, in Kant's view can be further reduced to more fundamental principles) whereas the validity of non-pure ratiocinia (...) additionally presupposes the validity of inferences which Kant calls consequentiae immediatae. I have argued that Kant's view is in some (not in all) essential features in accordance with Aristotle's view concerning perfect syllogisms and certainly leading to a tenable and interesting logical theory. As a result I have rejected not only the interpretation of Aristotle adopted by Theodor Ebert, but also the objections he has raised against Kant's logical theory. As far as Aristotle is concerned, Ebert has attempted to defend his position in the first part of his reply to my article published in J Gen Philos Sei (2009) 40: 357-365, and I have argued against this defence in issue 1 of the J Gen Philos Sei (2010) 41: 199-213 (cf. Ebert's answer in the same issue pp. 215-231). In the following discussion I deal with Eberts defence of his criticism of Kant published in the second part of his reply to my article (see J Gen Philos Sei (2009) 40: 365-372). I shall argue, that Kant's principle 'nota notae est nota rei ipsius' and his use of technical vocabulary stand up to the objections raised by Ebert. His attempts to prove that Kant's logical theory is defective are based on several misinterpretations. (shrink)

To be successful, collaboration at work requires its participants to have a common sense about what is happening and where things are heading. But how can collaborators have such a sense in common if what is going on continuously changes? This study investigates the joint communicative work participants in collaborative activity do to remain aligned on how things are going and where things are at for the purpose of maintaining a ground in common. Our test case for illustrating this joint (...) work is the fluid and constantly changing world of software development. Our study uses a transactional approach to show how software developers working together continuously make available what they are attuned to, which constitutes their common ground that allows actions and talk to make sense. The common ground enables a common, inherently shared sense of what is happening and how things are going. Rather than having “meaning” in themselves, signifiers (words, gestures, body movements, cursor movements) create and are part of the common ground against which they make sense. Signifiers are motivated by and produce an accented visible that is available to all group members; and this accented visible (including the signs) makes for the common ground. (shrink)

This study is about the interaction of scientific expertise and local knowledge in the context of a contested issue: the quality and quantity of safe drinking water available to some residents in one Canadian community. The authors articulate the boundary work in which scientific and technological expertise and discourse are played out against local knowledge and water needs to prevent the construction of a water main extension that would provide a group of residents with the same water that others in (...) the community already access. The authors draw on an extensive database constructed during a three-year ethnographic study of one community; the data base includes the transcript of a public meeting, newspaper clippings, interviews, and communications between residents and town council. The authors show not only that scientists and residents differ in their assessment of water quality and quantity but also that there is a penchant for undercutting residents in their attempts to make themselves heard in the political process.

In this chapter I offer an account of the nature, scope, and significance of Wolff’s claim that human beings have a duty to cognize moral good and evil. I illustrate that Wolff conceives of this duty as requiring that human beings both acquire distinct cognition of good and evil as well as avoid ignorance and error. Although Wolff intends for the duty to be quite demanding, he restricts its scope by, among other things, claiming it primarily concerns (...) those who have the skills, circumstances, and opportunity to acquire such cognition. Wolff calls these individuals the ‘inventors’ of the truths of morality and he considers himself to be such an inventor. I argue that part of the significance of this duty lies in the fact that Wolff conceives of himself as living up to it by writing the German Ethics, thereby sharing the knowledge he has ‘invented’ with others.

The contribution deals with the sources of Kant's criticism of the historical knowledge of philosophy. This criticism is an important motif in Kant's thought. Its contents are directed against Wolffianism. Nevertheless it was Christian Wolff who gave Kant the concept of the historical knowledge of philosophy. This concept is of great importance for Wolff, too. It can be traced back to the fight against Aristotelian scholastic philosophy. The reading of the traditional handbooks was criticized early, and the individual's (...) own meditation was challenged. Wolff formulated these intentions in his term: the historical knowledge of philosophy. Christian Thomasius and his followers, on the other hand, continued to criticize learning with the help of the memory, and they demanded the individual's own meditation. From this the slogan 'Selbstdenken' originated. Because of the opposition between the Wolffians and their opponents, for a long time 'self-thinking' and 'historical knowledge of philosophy' were treated side by side and independently of each other. Kant was the first to connect them definitively. He acknowledges the clarity of Wolff's terminology, but fills it up with the old content. (shrink)

In Chapter 8 of Kant’s Critique of Pure Reason and the Method of Metaphysics, one of Gabriele Gava’s aims is to argue that Kant’s critique of Wolff’s dogmatic method has two levels: one directed against Wolff’s metaphilosophical views and one attacking his actual procedures of argument. After providing a brief summary of the main claims Gava makes in Chapter 8 of his book, in this paper I argue two things. First, I argue against Gava’s claim that the two (...) forms of dogmatism he distinguishes between are incompatible. Second, I suggest, contrary to Gava, that Kant’s critique of these two forms of dogmatism both operate on the metaphilosophical level in the sense that they both target the dogmatist’s beliefs or theory about the method they take themselves to be following.

ABSTRACT Avner de-Shalit has devised a methodology for coming closer to a settled view in political philosophy which he calls ‘public reflective equilibrium’, extending ideas of John Rawls and Michael Walzer. De-Shalit proposes that the philosopher should come to an understanding of views outside the academy through extended interaction with members of the public. These discussions can and do lead to changes in the philosophical theory, from the introduction of new concepts, to new framings of issues or even novel (...) research questions. De-Shalit and I used this approach in our work Disadvantage. Reflecting on our work, I raise five questions: Who speaks for the public? How do you know you are asking the right questions? How should the theorist respond to judgements based on false empirical beliefs? What should be done when the public do not speak with one voice? Is equilibrium a reasonable aspiration? (shrink)

Unlocking the Second Antinomy: Kant and Wolff MICHAEL RADNER But how in this business can metaphysics be reconciled with geometry, when it seems easier to mate griffins with horses than to unite transcendental philosophy with geometry?' Kant, x756 THE SECOND ANTINOMY, treating the proof and refutation of bodies as composed of simple substances, is one of the more puzzling sections of the Critique of Pure Reason. The thesis argument especially baffles commentators. Edward Caird in t 889 said: "Kant's (...) statement of this argument is very obscure."Among commen- tators of our era, T. E. Wilkerson complains: "This argument is very muddy." Jonathan Bennett remarks: "The text, however, is not clear enough for us to be sure exactly what Kant is relying on in his argument for the Thesis. "~ Nor have commentators spared the antithesis argument. No one, to my knowledge, has interpreted the text so that the thesis and antithesis arguments come out valid and constitute a genuine antinomy. Yet Kant stated on more than one occasion that all the antinomy arguments are valid. The proofs "are not deceptions, but are well-founded, under the supposition that appearances or a sensible world which comprehends them all are things in themselves" .3 In the Prolego- "Physical Monadology," in Kant's Latin Writings: Translations, Commentaries, and Notes, trans. and ed.

This is a collection of sixteen essays by a diverse group of international scholars that offers a wide-ranging and contemporary perspective on the major aspects of Christian Wolff’s ethics. The volume focuses on Wolff’s German Ethics, arguably his most important and influential text on moral philosophy, but many of the chapters also consider the development of the basic tenets of Wolff’s moral theory in his later Latin writings. The contributions cover a range of topics, including the systematic (...) structure of the text itself and the relation between Wolff’s ethics and the preceding natural law tradition. Many chapters pay special attention to the core concepts of Wolff’s moral philosophy, such as obligation, perfection, the highest good, and happiness. Other notable topics include Wolff’s conception of moral judgment and moral education, as well as the role of psychology and anthropology in his ethical thought. The volume also contains discussion of the influence of Wolff’s ethics on subsequent figures such as C.A. Crusius, G.F. Meier, and Kant. As a whole, the volume seeks to establish the importance of Wolff’s German Ethics within the history of ethics as well as inspire others to engage with his thought. (shrink)

This paper is concerned with selecting an appropriate perspective from which to understand and evaluate social-decision procedures. Distinguishing between "agent rationality" and "option-rationality", the author argues that a rational agent may choose a social-decision procedure that is not itself agent-rational (but merely option-rational). The argument puts the voter's paradox in a context allowing evaluation of (a) its general import and (b) practical proposals for avoiding it in particular cases. Arrow's four conditions for a social-decision procedure are shown to have little (...) relevance to the understanding or evaluation of constitutions. The author concludes that the more fruitful perspective for discussing social-decision procedures is that of option-rationality rather than (as Arrow, Wolff, and others have supposed) that of agent-rationality.

Thorough comparison of Immanuel Kant’s and Christian Wolff’s divergent appraisals of the science of psychology reveals various ways in which Kant fundamentally altered the Wolffian philosophical apparatus that he inherited. Wolff conceived of a thoroughgoing interplay between empirical and rational psychology, of combining different sorts of cognition in psychology, and of a mathematical science of the soul, or psychometrics. Kant however rejected each of these particular theses and deemed psychology to be no natural science, “properly so-called.” This chapter (...) details these departures from Wolff, explains their basis, and concretizes an underlying contrast in Kant’s and Wolff’s respective philosophical approaches. Namely, whereas Wolff’s philosophical system is malleable, allowing for the combination of various kinds of cognition and methods, in Kant’s Critical philosophy, everything has its proper, preordained niche. At bottom, it is the unyielding rigor of Kant’s system that results in his pessimistic evaluation of the prospects for psychology. (shrink)

Karl Leonhard Reinhold publizierte Ende der 1780er-Jahre eine Reihe von Schriften, mit denen er beanspruchte, Immanuel Kants geschmackstheoretische Ausführungen der Kritik der Urteilskraft zu antizipieren. Ziel dieser Studie ist eine bis dato nicht vorgenommene umfassende kontextualisierende Analyse dieser frühen ästhetischen Ansätze, die u. a. auf das Schöne und die Kunst appliziert werden. Reinhold diskutiert die seiner Ansicht nach einseitigen Lustkonzeptionen von Dubos, Pouilly, Wolff, Mendelssohn, Sulzer und Helvétius, welche er mit seiner eigenen Theorie des Vergnügens ergänzt. Die Empfindungstheorie Ernst (...) Platners wird als ein holistischer Zugang gewürdigt. Reinholds Ausführungen nehmen Kants Geschmackskritik zwar nicht vorweg, doch sind sie mit dieser vereinbar und können als ihr vergnügens- und triebtheoretisches Fundament angesehen werden. Platners Einfluss ist dabei nur einer von vielen und verblasst neben dem von Kants Epistemologie und Ethik. Die Originalität von Reinholds Reflexionen liegt v. a. in einer transzendentalphilosophischen Aufwertung der Sinnlichkeit in ästhetischen Belangen und einem Vorläufermodell des freien Spiels der Erkenntniskräfte als einer starken und leichten Beschäftigung der Vorstellungskraft.

In this book, Michael Arbib, a researcher in artificial intelligence and brain theory, joins forces with Mary Hesse, a philosopher of science, to present an integrated account of how humans 'construct' reality through interaction with the social and physical world around them. The book is a major expansion of the Gifford Lectures delivered by the authors at the University of Edinburgh in the autumn of 1983. The authors reconcile a theory of the individual's construction of reality as a network (...) of schemas 'in the head' with an account of the social construction of language, science, ideology and religion to provide an integrated schema-theoretic view of human knowledge. The authors still find scope for lively debate, particularly in their discussion of free will and of the reality of God. The book integrates an accessible exposition of background information with a cumulative marshalling of evidence to address fundamental questions concerning human action in the world and the nature of ultimate reality.
