In diesem Aufsatz wird dafür argumentiert, dass interne Relationen, die als ein Beispiel für Bedingungen des Sprachgebrauchs stehen, einer Naturalisierung unterliegen. Um dies zu zeigen, wird der Begriff der Naturgeschichte in der Verwendung von Wittgensteins späten Schriften herangezogen. Im Gegensatz zu dem weit überwiegenden Teil der Literatur, der sich allein auf Wittgensteins Äußerungen zur Naturgeschichte des Menschen bezieht und beschränkt, werden hier seine Äußerungen zur Naturgeschichte der Farben im Mittelpunkt der Überlegungen gestellt, um herauszuarbeiten wie sich das Verhältnis von Logik (...) oder Grammatik und Welt verstehen läßt.

Der Begriff ‘Naturalismus’ wird hier im Sinne eines „schwachen“ Naturalismus verwendet werden. Der Terminus ist ein Versuch zu verstehen, was es bedeutet, daß der Mensch und der menschliche Geist Teil der natürlichen Welt sind. Zum besseren Verständnis wird dafür in der Mehrzahl der hier veröffentlichten Arbeiten der Begriff der Naturgeschichte herangezogen, der auf die Entwicklungsgeschichte des Menschen verweist. Die hier abgeruckten Beiträge werden dabei zeigen, inwiefern diese Position eines schwachen Naturalismus in philosophischer Hinsicht interessant ist. Es sollen mit anderen Worten (...) die systematischen Leistungen eines schwachen Naturalismus, der an das Konzept der Naturgeschichte anschließt, deutlich gemacht werden. (shrink)

Analyzing the ancient Greek point of view concerning anger, shame and justice and a very modern one, one can see, that anger has a regulative function, but shame does as well. Anger puts the other in his place, thereby regulating hierarchies. Shame regulates the social relations of recognition. And both emotions also have an evaluative function, because anger evaluates a situation with regard to a humiliation; shame, with regard to a misdemeanor. In addition, attention has to be paid to the (...) correct molding of these emotions and the correct ways of using them in rearing to be good or just (i.e., in personality formation. (shrink)

Abstract:We analyzed co-citation patterns in 332,498 articles published in Anglophone psychology journals between 1946 and 1990 to estimate (1) when cognitive psychology first emerged as a clearly delineated subdiscipline, (2) how fast it grew, (3) to what extent it replaced other (e.g., behaviorist) approaches to psychology, (4) to what degree it was more appealing to scholars from a younger generation, and (5) whether it was more interdisciplinary than alternative traditions. We detected a major shift in the structure of co-citation networks (...) between approximately 1955 and 1975 and draw novel conclusions about the developments commonly referred to as "the cognitive turn.".

This paper works out which conceptual and theoretical preconditions have to be met, among others, in order for a living creature to be able to have a feeling of being alive beyond the mere capacity for sensation. For the emergence of such a feeling, which can be equated with a rudimentary phenomenal consciousness (1.), it is not enough for the organism to be alive (2. a.). Rather it has to be able to conceive its body as a unit and to (...) relate its sensations to this unit (2. b.). Moreover mobility (2. c.), a basic sense of possibility (2. d.) and a rudimentary sense of time (2. e.) are also necessary. The analysis of these preconditions relies primarily on Aristotelian theoretical approaches, encompassing both historical interpretation (3. a.), and systematic work, which includes a look at the current debates in the analytic philosophical tradition (3. b.).

Gefühl und Wissen wurden in der Philosophie meist als Gegensätze gesehen. So ist Wissen traditioneller Weise als begründete oder gerechtfertigte wahre Meinung definiert. Kann man, wenn man eine solche Definition zu Grunde legt, sagen, dass man weiß, dass man liebt? Was sollte als Begründung oder Rechtfertigung gelten können?

Ziel dieses systematischen Ansatz ist es eine Antwort auf die Frage der Wahrheitswertzuschreibung für irreale Konditionalsätze zu geben. Die große philosophische Fragestellung, die damit verfolgt wird, betrifft das Verhältnis von Sprache und Welt, Wirklichkeit und Möglichkeit. Am Ende wird geklärt inwiefern logische Strukturen einen Weltbezug haben. Damit ist ein Vorschlag der Naturalisierung der Normativität der Semantik verbunden.

All spaces are assumed to be separable and metrizable. We show that, assuming the Axiom of Determinacy, every zero-dimensional homogeneous space is strongly homogeneous (i.e. all its non-empty clopen subspaces are homeomorphic), with the trivial exception of locally compact spaces. In fact, we obtain a more general result on the uniqueness of zero-dimensional homogeneous spaces which generate a given Wadge class. This extends work of van Engelen (who obtained the corresponding results for Borel spaces), complements a result of van (...) Douwen, and gives partial answers to questions of Terada and Medvedev.

The feeling of being alive still constitutes a major blind spot of contemporary affective sciences research. The mainstream view accepts it as an ‘umbrella notion’ comprising different states, such as M. Ratcliffe’s «feelings of being», T. Fuchs’s «feeling of being alive», E.M. Engelen’s «Gefühl des Lebendigseins», etc. In contrast, I argue for an account of the feeling of being alive as a unique feeling that can be described in several ways. Empirical support for this view comes mainly from Carvalho (...) and Damasio’s hypothesis of the distinctiveness of the interoceptive system as the physiological underpinning of this feeling. This account is also in line with many other approaches recognizing the role of interoception proper in mind and subjectivity grounding, collected by Tsakiris and De Presteer. Over recent decades, Damasio’s organic descriptions have been widely acknowledged as neurophysiological counterparts of philosophical/psychological concepts. However, in my view they have been often misinterpreted, especially due to the mainstream Ratcliffian interpretation mediating his ideas amongst philosophers. Throughout the paper, a critical inquiry into Damasio’s conceptualization is provided, by means of conceptual analysis and an overall taxonomy of the several affective states he has proposed over the past few decades. Ultimately, a critical discussion of his own account of the feeling of being alive is offered from a philosophical viewpoint. (shrink)

The responses to the questions of why? when?, how?, where?, and in what ways? business ethics should be taught in the BusinessEthics classroom inundate the scholarly literature. Yet, to date, despite some very interesting ideas, with respect to the answers givento the above question, not only has nothing even close to consensus been reached, but this particular area of pedagogy is instagnation—authors still challenge both the very idea of teaching business ethics as well as the practical value of such courses (...) for ourstudents once they graduate to the corporate world.In this paper I will suggest that the reason for this lack of pedagogical progress is that there has been a serious oversight regarding the most important teaching question of all: Who? I will show that the pedagogical issue of whom should be teaching Business Ethics has been largely ignored, skirted or answered incorrectly. I will then boldly argue that the only necessary condition for successful courses inBusiness Ethics is that they be taught by experts in ethics, i.e., Ph.D.s in philosophy. (shrink)

I. Introduction Two kinds of remedies have traditionally been employed for breach of contract: legal relief and equitable relief. Legal relief normally takes the form of money damages. Equitable relief normally consists either of specific performance or an injunction – that is, the party in breach may be ordered to perform an act or to refrain from performing an act. In this article I will use a “consent theory of contract” to assess the choice between money damages and specific performance. (...) According to such a theory, contractual obligation is dependent on more fundamental entitlements of the parties and arises as a result of the parties' consent to transfer alienable rights. My thesis will be that the normal rule favoring money damages should be replaced with one that presumptively favors specific performance unless the parties have consented to money damages instead. The principal obstacle to such an approach is the reluctance of courts to specifically enforce contracts for personal services. The philosophical distinction between alienable and inalienable rights bolsters this historical reticence, since a right to personal services may be seen as inalienable. I will then explain why, if the subject matter of a contract for personal services is properly confined to an alienable right to money damages for failure to perform, specific enforcement of such contracts is no longer problematic. Finally, I shall consider whether the subject matter of contracts for corporate services is properly confined to money damages like contracts for personal services, or whether performance of corporate services can be made the subject of a valid rights transfer and judicially compelled in the same manner as contracts for external resources.

Clinical diagnostic medicine is an experimental science based on observation, hypothesis making, and testing. It is an use dynamic process that involves observation and summary, diagnostic conjectures, testing, review, observation and summary, new or revised conjectures, i.e. it is an iterative process. It can then be said that diagnostic hypotheses are also ‘observation-laden’. My aim is to enlarge on the strategies of medical diagnosis as these are meshed in training and clinical experience—that is, to describe the patterns of reasoning used (...) by experienced clinicians under different diagnostic circumstances and how these patterns of inquiry allow further insight into the evaluation and treatment of patients. I do not aim to present a theory and illustrate it with examples; I wish rather am to let a realistic example, similar to actual clinical scenarios, direct the exposition. To this end, I introduce an account of medical diagnosis—briefly comparing and contrasting it to other accounts—in order to focus on discussing the process of diagnosis through a detailed clinical case.

Four models of forgiveness are identified; the health model, the philosophical model, the Christian model and the prosocial model. All define the term ‘forgiveness’ in a way which is consistent with their particular perspective. The authors offer a definition of forgiveness and propose an integrated model of forgiveness which seeks to incorporate contributions from all four areas, but is not biased towards any one model. Four levels of transgression are identified and categorized according to the degree of perceived damage. Apology-automatic (...) and apology-dependent responses are distinguished from a forgiveness response which is restricted to Levels 3 and 4. The advantages of adopting a forgiveness strategy for both the forgiver and forgiven as opposed to other responses, i.e., revenge, denial, and condoning are discussed. The authors provide a definition and model which integrates the important contributions from each of the areas discussed. (shrink)

It is a thankless task to have to reply to Professor Murray Krieger’s “Retrospective.” Qui s’excuse, s’accuse, and since I cannot ask my readers to embark on their own retrospective of my writings and test them for consistency, I have little chance of restoring my reputation in their eyes. Hence I would have been happier to leave Professor Krieger to his agonizing, if he did not present himself the “spokesman” for a significant body of theorists who appear to have acclaimed (...) my book on Art and Illusion without ever having read it. The followers of this school of criticism—of which Professor Krieger is a prominent member—had apparently convinced themselves that the book lent support to an aesthetics in which the notions of reality and of nature had no place. They thought that I had subverted the old idea of mimesis and that all that remained were different systems of conventional signs which were made to stand for an unknowable reality. True, professor Krieger admits that I never endorsed such an interpretation of my views, and he even concedes that there are passages in Art and Illusion which contradict such an out-and-out relativism, but he wants to convince his readers that these contradictions lead precisely to the ambiguities he now proposes to analyse.If he were right that the book encourages such a misreading, all I could do would be to express my regrets for having failed to make myself sufficiently clear. Luckily I can draw comfort from the fact that unlike these literary critics, the leading archaeologist of this country, Professor Stuart Piggott, had no difficulty at all in discerning my meaning and profiting from my arguments. In his Walter Neurath Memorial Lecture of 1978, entitled Antiquity Depicted: Aspects of Archaeological Illustration, the author did me the honour of taking a statement from my book as his starting point. It is the passage at the end of part I in which I recapitulate the content of the first two chapters:What matters to us is that the correct portrait, like the useful map, is an end product on a long road through schema and correction. It is not a faithful record of a visual experience but the faithful construction of a relational mode.Neither the subjectivity of vision nor the sway of conventions need lead us to deny that such a model can be constructed to any required degree of accuracy. What is decisive here is clearly the word “required.” The form of a representation cannot be divorced from its purpose and the requirements of the society in which the given visual language gains currency.1 1. E. H. Gombrich, Art and Illusion: A Study in the Psychology of Pictorial Representation, A. W. Mellon Lectures in the Fine Arts, 1956 , p. 90. E. H. Gombrich was director of the Warburg Institute and Professor of the History of the Classical Tradition at the University of London from 1959 to 1976. His many influential works include The Story of Art, Art and Illusion, Meditations on a Hobby Horse, The Sense of Order, Ideals and Idols, The Image and the Eye, and, most recently, Tributes. His previous contributions to Critical Inquiry include “The Museum: Past, Present and Future and “Standards of Truth: The Arrested Image and the Moving Eye”. (shrink)

Ancient moral philosophers, especially Aristotle and his followers, typically shared the assumption that ethics is primarily concerned with how to achieve the final end for human beings, a life of “happiness” or “human flourishing.” This final end was not a subjective condition, such as contentment or the satisfaction of our preferences, but a life that could be objectively determined to be appropriate to our nature as human beings. Character traits were treated as moral virtues because they contributed well toward this (...) ideal life, either as means to it or as constitutive aspects of it. Traits that tended to prevent a “happy” life were considered vices, even if they contributed to a life that was pleasant and what a person most wanted. The idea of “happiness” was central, then, in philosophical efforts to specify what we ought to do, what sort of persons we should try to become, and what sort of life a wise person would hope for.

Philosophers have debated for millennia about whether moral requirements are always rational to follow. The background for these debates is often what I shall call “the self-interest model.” The guiding assumption here is that the basic demand of reason, to each person, is that one must, above all, advance one's self-interest. Alternatively, debate may be framed by a related, but significantly different, assumption: the idea that the basic rational requirement is to develop and pursue a set of personal ends in (...) an informed, efficient, and coherent way, whether one's choice of ends is based on self-interested desires or not. For brevity I refer to this as “the coherence-and-efficiency model.” Advocates of both models tend to think that, while it is sufficiently clear in principle what the rational thing to do is, what remains in doubt is whether it is always rational to be moral. They typically assume that morality is concerned, entirely or primarily, with our relations to others, especially with obligations that appear to require some sacrifice or compromise with the pursuit of self-interest.

Climate science denial results from ignorance and perpetuates ignorance about scientific facts and methods of inquiry. In this paper, I explore climate science denial as a type of active ignorance...

In this paper I shall venture into an area with which I am not very familiar and in which I feel far from confident; namely into phenomenology. My main motive is not to get away from standard, boring, methodological questions like those of induction and demarcation; but the conviction that a phenomenological account of the empirical basis forms a necessary complement to Popper's falsificationism. According to the latter, a scientific theory is a synthetic and universal, hence unverifiable proposition. In fact, (...) in order to be technologically useful, a scientific hypothesis must refer to future states-of-affairs; it ought therefore to remain unverified. But in order to be empirical, a theory must bear some kind of relation to factual statements. According to Popper, such a relation can only be one of potential conflict. Thus a theory T will be termed scientific if and only if T is logically incompatible with a so-called basic statement b, where b is both empirically verifiable and empirically falsifiable. In other words: T is scientific if it entails ¬b; where b, hence also ¬b, is an empirically decidable proposition. (shrink)

When I agreed to lecture to-night I stipulated that I might be allowed to interpret the subject announced so as to let my treatment relate less to the subject in general than to some particular aspects which happen to have been interesting me lately. Professor Whitehead, Sir Arthur Eddington, and Sir James Jeans have given to the world brilliant accounts of the present position of physics in relation to mathematics and philosophy. What I have to say bears to their writings, (...) the humble relation of an example to a piece of book-work, or of an application of a theorem to the theorem itself. (shrink)

This article describes a left-corner parser implemented within a cognitively and neurologically motivated distributed model of memory. This parser's approach to syntactic ambiguity points toward a tidy account both of surprisal effects and of locality effects, such as the parsing breakdowns caused by center embedding. The model provides an algorithmic-level account of these breakdowns: The structure of the parser's memory and the nature of incremental parsing produce a smooth degradation of processing accuracy for longer center embeddings, and a steeper degradation (...) when they are nested, in line with recall observations by Miller and Isard and speed-accuracy trade-off observations by McElree et al.. Modeling results show that this effect is distinct from the effects of ambiguity and exceeds the effect of mere sentence length. (shrink)

Examining the ways in which philosophers from Plato onwards have used the concept of power, this work develops a field theory of power that rejects many of the reigning assumptions made about power. Incorporating the insights of feminist theorists, it argues that power has a positive as well as a negative role to play in social relations.

The present study investigated children's understanding that an object's history may increase its significance, an appreciation that underpins the concept of historical authenticity (i.e., the idea that an item's history determines its true identity, beyond its functional or material qualities, leading people to value real items over copies or fakes). We examined the development of historical significance through the lens of parent–child conversations, and children's performance on an authenticity assessment. The final sample was American, 79.2% monoracial White, and mid-high socio-economic (...) status (SES) and included 48 parent–child pairs: 24 with younger children (R = 3.5 to 4.5 years) and 24 with older children (R = 5.5 to 6.5 years). Parent–child pairs discussed three books we created, with three storylines: a museum (culturally authentic) storyline, a clean-up (personally authentic) storyline, and a control storyline. Across measures, conversations suggested that authenticity may begin as a “placeholder concept” that is initially rooted in a broad appreciation for the significance of old objects and only later filled in with specifics. This placeholder initially directs children's learning about authenticity by linking, in an unspecified way, the value and significance of objects to their past. For example, we found that young children appropriately appealed to history (vs. perceptual or functional features of objects) in contexts regarding authentic objects but struggled in determining which objects were more significant on the post-test assessment, suggesting that they attend to object history but are not yet sure how histories matter for making authenticity judgments. We also found some evidence that directing children's attention toward conceptual information related to object history may in turn direct them away from material or perceptual considerations, as seen in trade-offs in parents’ and children's conversations. Together, this exploratory report offers many new avenues for work on the development of authenticity concepts in childhood. (shrink)

Imagine a society of fisherfolk, who, in the state of nature, fish on a lake of finite size. Fishing on the lake is characterized by decreasing returns to scale in labor, because the lake's finite size imply that each successive hour of fishing labor is less effective than the previous one, as the remaining fish become less dense in the lake. In the state of nature, the lake is commonly owned: each fishes as much as he pleases, and, we might (...) suppose, calculates his fishing plan by taking the labor of the others as given, as he sees it. Each knows that the distribution of fish will be proportional to labor expended among the fisherfolk: if I fish twice as long as you, I will end up with twice as much fish as you. This is not due to some kind of concern with equity among the fisherfolk; it is a technological fact, implied by the assumption that fishing labor is homogeneous, and all are equally likely to catch a fish in a unit of time. An equilibrium under common ownership can be thought of as a Nash equilibrium of the game where each computes his optimal fishing plan, given the labor of the others and knowing what the consequent distribution of fish would be.

« Mais pourquoi diable les humains, sur leur petite planète bleue, s’intéressent-ils à ce point à moi, qui ne suis qu’un extraterrestre? » : telle est la question que pose un E.

The questions of observational error and ambiguity of interpretation that have been raised in connection with the reported observation of a magnetic monopole have precipitated a situation calling for some further insight into the pairing principles of nature. A basic distinction relates to whether or not a pair is “ordered” (e.g., sexual pair) or without a priori order (e.g., mirror pair). It is shown that the polarity of electric charge is to be regarded as an example of pairing without an (...) intrinsic a priori order. It then follows that “action” also exhibits a pairing without a priori order. The relation ofPC andTC to unordered and ordered pairing is discussed, with neutral kaon pairing as a striking example of ordered pairing. The pairing of magnetic charge, if it exists, becomes an ordered pairing! (shrink)
