This study investigated the extent to which people interpret real-life moral dilemmas in terms of an internal moral orientation, as Gilligan (1982, 1988) has suggested, or in terms of the content of the dilemma, as Wark and Krebs (1996, 1997) have reported. Thirty women and 30 men listed the issues they saw in descriptions of real-life prosocial, antisocial and social pressure types of moral dilemma. Results revealed that Gilligan's model underestimates the influence of dilemma content. Moral dilemmas differed in (...) the extent to which they were viewed in terms of the same issues by different participants. There was relatively little within-person consistency in moral orientation. There were four gender differences. Compared to men, women rated social pressure dilemmas as involving more care-orientated issues, and prosocial dilemmas as more significant. Compared to women, men viewed all dilemmas as involving more justice-based issues, and reported experiencing more antisocial dilemmas. (shrink)
Rorty has a particular picture of what goes into this split, of what specific features of Wittgenstein's own philosophical development determine the distance that separates his later work from what goes on in the professionalized field of philosophy. In particular, he fully assumes the official account of the relation between the early and later work as itself providing an explanation of Wittgenstein's split..
We contribute to the empirical debate on whether we understand and predict mental states by using simulation (simulation theory) or by relying on a folk psychological theory (theory theory). To decide between these two fundamental positions, it has been argued that failure to predict other people's choices would be challenging evidence against the simulation view. We test the specific claim that people prefer the rightmost position in choosing among equally valued objects, and whether or not this position bias can be (...) correctly predicted. A series of experiments shows that the bias appears only in a specific spatial arrangement and that it can be correctly predicted given adequate imaginative input. In concert with other recent findings on the correct prediction of choices these findings do actually strengthen, rather than challenge, the simulation account on the prediction of mental states.

Those who invoke the word self-deception to represent one phenomenon often argue that those who use it to represent another are misusing the construct. Better to recognize that self-deception is a fuzzy concept that may be used to represent a variety of mental processes and states, and to direct our energy toward distinguishing empirically among its forms and functions.
Abstract Forty male and female adults responded to two forms of Kohlberg's test??one in the standard third?person form, and the other imagining themselves as the protagonists in Kohlberg's dilemmas. Females obtained slightly lower moral maturity scores than males across both forms, but there were no sex differences in moral orientation. There were no significant effects for the perspective from which Kohlberg's test was taken, on either moral maturity or moral orientation. Care?oriented moral judgements were more prevalent in dilemmas involving life (...) vs. law conflicts than in dilemmas involving conscience vs. punishment conflicts. Subjects did not consistently make either care? or justice?oriented moral judgements. There was a significant negative correlation between the frequency of care?oriented judgements and moral maturity for males, but not for females. Although these results are partially consistent with the possibility that Kohlberg's test and scoring system are biased against females, they do not support the assumption that females make more care?oriented moral judgements than males on Kohlberg's test, or, indeed, that members of either sex display enough consistency in care?and justice?based moral judgements on Kohlberg's test for such judgements to serve as the basis of moral orientations.

Abstract People rarely make the types of moral judgement evoked by Kohlberg's test when they make moral decisions in their everyday lives. The anticipated consequences of real?life moral decisions, to self and to others, may influence moral choices and the structure of moral reasoning. To understand real?life moral judgement we must attend to its functions, which, although they occasionally involve resolving hypothetical moral dilemmas like those on Kohlberg's test, more often involve promoting good social relations, upholding favourable self?concepts and justifying (...) self?interested behaviour. We argue that a functional model of moral judgement and moral behaviour derived from evolutionary theory may supply a better account of real?life morality than the Kohlbergian model. (shrink)
Abstract Twenty?four second? and third?grade children were given two cognitively?based role?taking tests developed by Flavell et al. (1968). The children's social behaviour was observed over a two?month period. It was coded according to a scheme introduced by the anthropologists Whiting and Whiting (1975) which produces composite scores of egoism and altruism. Teachers rated the children's social behaviour and role?taking ability. IQ scores were obtained from school records. Tests of the reliability and validity of the measures of role?taking and altruism were (...) positive. Role?taking ability was positively correlated with naturally?occurring altruistic behaviour and teacher's ratings of altruism. IQ was positively correlated with role?taking ability, and tended to be positively correlated with altruism. The correlation between role?taking and altruism was marginally significant with IQ partialled out. The results were consistent with the conclusion that role?taking ability increases the disposition to behave altruistically in third?grade children. (shrink)
Biological, cognitive, and learning explanations of altruism, selfishness, and self-control can be integrated in terms of adaptive strategies. The key to understanding why humans and other animals sometimes resist temptation and sacrifice their immediate interests for the sake of others lies in mapping the design of the evolved mental mechanisms that give rise to the decisions in question.
Refinements in Darwin’s theory of the origin of a moral sense create a framework equipped to organize and integrate contemporary theory and research on morality. Morality originated in deferential, cooperative, and altruistic ‘‘social instincts,’’ or decision-making strategies, that enabled early humans to maximize their gains from social living and resolve their conflicts of interest in adaptive ways. Moral judgments, moral norms, and conscience originated from strategic interactions among members of groups who experienced confluences and conflicts of interest. Moral argumentation buttressed (...) by moral reasoning is equipped to generate universal and impartial moral standards. Moral beliefs and standards are products of automatic and controlled information-processing and decision making mechanisms. To understand how people make moral decisions, we must understand how early evolved mechanisms in the old brain and recently evolved mechanisms in the new brain are activated and how they interact. Understanding what a sense of morality is for helps us understand what it is. (shrink)
Evolutionary theory supplies a framework for integrative models of social behavior. In addition to those that include conditioning, evolutionary theory is equipped to explain the acquisition of structures designed to enable individuals to learn by observing others, create mental models of the environment, and coordinate social interactions by taking the perspectives of others.
The personal computer has become the primary research tool in many scientific and engineering disciplines. The role of the computer has been extended to be an experimental and modelling tool both for convenience and sometimes necessity. In this paper some of the relationships between real models and virtual models, i.e. models that exist only as programs and data structures, areexplored. It is argued that the shift from experimenting with real objects to experimentation with computer models and simulations may also require (...) a new approach for evaluating scientific theories derived from these models. Accepting the additional sets of assumptions that are associated with computer models and simulations requires ‘leaps of faith’, which we may not want to make in order to preserve scientific rigor. There are problems in providing acceptable arguments and explanations as to why a particular computer model or simulation should be judged scientifically sound, plausible, or even probable. These problems not only emerge from models that are particularly complex, but also in models that suffer from being too simplistic. (shrink)
Seeing Wittgenstein Anew is the first collection to examine Ludwig Wittgenstein's remarks on the concept of aspect-seeing, showing that it was not simply one more topic of investigation in Wittgenstein's later writings but rather a pervasive and guiding concept in his efforts to turn philosophy's attention to the actual conditions of our common life in language. The essays in this volume open up novel paths across familiar fields of thought: the objectivity of interpretation, the fixity of the past, the acquisition (...) of language, and the nature of human consciousness. Significantly, they exemplify how continuing consideration of the interrelated phenomena of aspect-seeing might produce a fruitful way of doing philosophy in a new century. (shrink)
In this paper I offer an account of the meaning of must and can within the framework of possible worlds semantics. The paper consists of two parts: the first argues for a relative concept of modality underlying modal words like must and can in natural language. I give preliminary definitions of the meaning of these words which are formulated in terms of logical consequence and compatibility, respectively. The second part discusses one kind of insufficiency in the meaning definitions given in (...) the first part, which arise from the ex falso quodlibet paradox of logical consequence. In stepwise fashion, I make an attempt to avoid most of the consequences of this paradox for the meaning definitions of must and can. (shrink)
Situation semantics was developed as an alternative to possible worlds semantics. In situation semantics, linguistic expressions are evaluated with respect to partial, rather than complete, worlds. There is no consensus about what situations are, just as there is no consensus about what possible worlds or events are. According to some, situations are structured entities consisting of relations and individuals standing in those relations. According to others, situations are particulars. In spite of unresolved foundational issues, the partiality provided by situation semantics (...) has led to some genuinely new approaches to a variety of phenomena in natural language semantics. In the way of illustration, this article includes relatively detailed overviews of a few selected areas where situation semantics has been successful: implicit quantifier domain restrictions, donkey pronouns, and exhaustive interpretations. It moreover addresses the question of how Davidsonian event semantics can be embedded in a semantics based on situations. Other areas where a situation semantics perspective has led to progress include attitude ascriptions, questions, tense, aspect, nominalizations, implicit arguments, point of view, counterfactual conditionals, and discourse relations.

They are expressives, too. There is a phonology. There is a syntax. There is a compositional semantics. There are interesting interactions to investigate. German, Greek, and Papago are known examples of discourse particle languages. Intonation has been said to have similar uses in other languages.
This means that, to know which conditionals are true, was considered to be just as important as to know what happens after our death. It was the conditionals which divided DIODOROS KRONOS and his pupil PHILO. Later, CHRYSIPPOS joined the quarrel and they all died without reconcilement.
What are facts, situations, or events? When Situation Semantics was born in the eighties, I objected because I could not swallow the idea that situations might be chunks of information. For me, they had to be particulars like sticks or bricks. I could not imagine otherwise. The first manuscript of “An Investigation of the Lumps of Thought” that I submitted to Linguistics and Philosophy had a footnote where I distanced myself from all those who took possible situations to be units (...) of information. In that context and at that time, this meant Jon Barwise and John Perry. (shrink)
Kratzer 1998 proposes that certain indefinite determiners (at least in some of their uses) might be variables for (Skolemized) choice functions that receive a value from the utterance context. What does it mean for a choice function variable to receive a value from the context of utterance? How can a context provide such a function? To sharpen intuitions, here is an example describing a custom from my home town Mindelheim. After every funeral, all the mourners gathered around the still open (...) grave say a prayer that starts with the words: “And now let us pray for the person among us who will die next.” Suppose an anthropologist attended one or more funerals in Mindelheim, and reports on what she found out in a lecture using (1), or the more general (2).

The deontic modal must has two surprising properties: an assertion of must p does not permit a denial of p, and must does not take past tense complements. I first consider an explanation of these phenomena that stays within Angelika Kratzer’s semantic framework for modals, and then offer some reasons for rejecting that explanation. I then propose an alternative account, according to which simple must sentences have the force of an imperative.
This article discusses some of the ways in which natural language can express modal information – information which is, to a first approximation, about what could be or must be the case, as opposed to being about what actually is the case. It motivates, explains, and raises problems for Angelika Kratzer's influential theory of modal auxiliaries, and introduces a new approach to one important debate about the relationships between modality, evidentiality, context change, and imperative force.
This paper is about the semantic analysis of referentially opaque verbs like seek and owe that give rise to nonspecific readings. It is argued that Montague's categorization (based on earlier work by Quine) of opaque verbs as properties of quantifiers runs into two serious difficulties: the first problem is that it does not work with opaque verbs like resemble that resist any lexical decomposition of the seek ap try to find kind; the second one is that it wrongly predicts de (...) dicto (i.e. narrow scope) readings due to quantified noun phrases in the object positions of such verbs. It is shown that both difficulties can be overcome by an analysis of opaque verbs as operating on properties. This is a strongly modified version of a paper entitled lsquoDo We Bear Attitudes towards Quantifiers?rsquo that I have presented at conferences in Gosen (Gesellschaft für Sprachwissenschaft), Ithaca (SALT I), and Konstanz (Lexikon). I owe a special debt to Hans Kamp and Arnim von Stechow for shaping my views on the subject of this paper during the past ten years or so. Comments from and discussions with the following friends and colleagues have also led to considerable improvements: Heinrich Beck, Steve Berman, David Dowty, Veerle van Geenhoven, Fritz Hamm, Irene Heim, Wolfgang Klein, Angelika Kratzer, Michael Morreau, Barbara Partee, Mats Rooth, Roger Schwarzschild, Wolfgang Sternefeld, Emil Weydert, Henk Zeevat, and three referees.

This note is a reply to "On the Lumping Semantics of Counterfactuals" by Makoto Kanazawa, Stefan Kaufmann, and Stanley Peters. It shows first that the first triviality result obtained by Kanazawa, Kaufmann, and Peters is already ruled out by the constraints on admissible premise sets listed in Kratzer (1989). Second, and more importantly, it points out that the results obtained by Kanazawa, Kaufmann, and Peters are obsolete in view of the revised analysis of counterfactuals in Kratzer..
The BPR assumes that we already know how sentences are partitioned into focused and backgrounded material, and this is quite legitimate, given the literature on the topic (see e.g. Krifka (1991), von Stechow (1991)). If the BPR was true, no more would have to be said about the meaning of focus. The behavior of whatever inferences are generated by backgrounding could be taken care of by theories dealing with the projection of presuppositions of the familiar kind, the presuppositions of definite (...) descriptions, clefts, or factives, for example. This is a non-trivial and interesting claim. (shrink)
The adjectival passive construction that is traditionally called ‘Zustandspassiv’ (‘state passive’) in German seems to have the same syntactic and semantic properties as its English cousin, except that it is easier to identify. German state or adjectival passives select the auxiliary sein (‘be’), and are therefore clearly distinguished from verbal or ‘Vorgangs’- passives (‘process passives’), which use the auxiliary werden (‘get’, ‘become’). In spite of their appearance, German state passives do not form a homogenious class, however. There are two important (...) subclasses that behave differently with respect to the adverbial immer noch (‘still’), for example2. (shrink)
In his original semantics for counterfactuals, David Lewis presupposed that the ordering of worlds relevant to the evaluation of a counterfactual admitted no incomparability between worlds. He later came to abandon this assumption. But the approach to incomparability he endorsed makes counterintuitive predictions about a class of examples circumscribed in this paper. The same underlying problem is present in the theories of modals and conditionals developed by Bas van Fraassen, Frank Veltman, and Angelika Kratzer. I show how to reformulate (...) all these theories in terms of lower bounds on partial preorders, conceived of as maximal antichains, and I show that treating lower bounds as cutsets does strictly better at capturing our intuitions about the semantics of modals, counterfactuals, and deontic conditionals.

Resultatives raise important questions for the syntax-semantics interface, and this is why they have occupied a prominent place in recent linguistic theorizing. What is it that makes this construction so interesting? Resultatives are submitted to a cluster of not obviously related constraints, and this fact calls out for explanation. There are tough constraints for the verb, for example.
I will assume (without explicitly argue for it here) that the verb’s external argument is not an argument of the verb root itself, but is introduced by a separate head in a neo-Davidsonian way. The content argument can be saturated by DPs denoting the kinds of things that can be believed or reported.
Both Kratzer 1981 (“Partition and Revision”) and Kratzer 1989 (“Lumps of Thought”) assume that the truth of counterfactuals depends on a parameter. The parameter provides a set of propositions that uniquely characterizes the actual world in Kratzer 1981, and a so-called “set of propositions relevant for the truth of counterfactuals” in Kratzer 1989. Both papers try to find empirical constraints for the relevant sets, but - crucially - without characterizing them uniquely. The vagueness and context-dependency of counterfactuals is assumed to (...) be in part due to the fact that the set of propositions that the truth of counterfactuals depends on is underdetermined.

This paper develops a notion of mechanistic information that can be used to explain the continuities of such processes. We compare them to processes (including the Krebs cycle) that do not involve information. We compare our conception of mechanistic information to some familiar notions including (...)

This paper provides an update semantics for counterfactual conditionals. It does so by giving a dynamic twist to the ‘Premise Semantics’ for counterfactuals developed in Veltman (1976) and Kratzer (1981). It also offers an alternative solution to the problems with naive Premise Semantics discussed by Angelika Kratzer in ‘Lumps of Thought’ (Kratzer, 1989). Such an alternative is called for given the triviality results presented in Kanazawa et al. (2005, this issue).
This paper pursues some of the consequences of the idea that there are (at least) two sources for distributive/cumulative interpretations in English. One source is lexical pluralization: All predicative stems are born as plurals, as Manfred Krifka and Fred Landman have argued. Lexical pluralization should be available in any language and should not depend on the particular make-up of its DPs. I suggest that the other source of cumulative/distributive interpretations in English is directly provided by plural DPs. DPs with plural (...) agreement features can ‘release’ those features to pluralize adjacent verbal projections. If there is a lexical source for distributive/cumulative interpretations, there should be instances of such interpretations with singular DPs. But there should also be cases of distributive/cumulative interpretations that require the presence of DPs with plural agreement morphology. (shrink)
In this article we will explore the consequences of adopting recent proposals by Chomsky, according to which the syntactic derivation proceeds in terms of phases. The notion of phase – through the associated notion of spellout – allows for an insightful theory of the fact that syntactic constituents receive default phrase stress not across the board, but as a function of yet-to-be-explicated conditions on their syntactic context. We will see that the phonological evi- dence requires us to modify somewhat the (...) theory of which functional categories actually define a phase. Patterns of default, syntax-determined, phrase stress are argued to result from a prosodic spellout requiring the highest phrase in the spellout domain to correspond to a major prosodic phrase in phonological representation, and carry major phrase stress.

Standard accounts of semantics for counterfactuals confront the true–true problem: when the antecedent and consequent of a counterfactual are both actually true, the counterfactual is automatically true. This problem presents a challenge to safety-based accounts of knowledge. In this paper, drawing on work by Angelika Kratzer, Alan Penczek, and Duncan Pritchard, we propose a revised understanding of semantics for counterfactuals utilizing machinery from generalized quantifier theory which enables safety theorists to meet the challenge of the true–true problem.
Empirical research on counterfactual thinking has found a closeness effect: people report higher negative affect if an actual outcome is close to a better counterfactual outcome. However, it remains unclear what actually is a ?close? miss. In three experiments that manipulate close counterfactuals, closeness effects were found only when closeness was unambiguously defined either with respect to a contrasted alternative, or with respect to a categorical boundary. In a real task people failed to report greater negative affect when encountering a (...) close numerical miss, while they predicted greater negative affect hypothetically. These results show that counterfactual closeness effects on affect depend on closeness being accessible and unambiguously defined. (shrink)
In a series of recent articles Angelika Kratzer has argued that the standard account of modality along Kripkean lines is inadequate in order to represent context-dependent modals. In particular she argues that the standard account is unable to deliver a non-trivial account of modality capable of overcoming inconsistencies of the underlying conversational background.
Since Krebs and Davies’s (1978) landmark publication, it is acknowledged that behavioural ecology owes much to the ethological tradition in the study of animal behaviour. Although this assumption seems to be right—many of the first behavioural ecologists were trained in departments where ethology developed and matured—it still to be properly assessed. In this paper, I undertake to identify the approaches used by ethologists that contributed to behavioural ecology’s constitution as a field of inquiry. It is my contention that the (...) current practices in behavioural biology owe ethology something much subtler than the simple transposition of Tinbergen’s Four Problems for heuristic purposes. Demonstrating what ethology inherited from the long naturalist tradition shows the tensions that strained the field and that later led to the loss of both its unity and its specificity. It also allows for a precise delineating of what behavioural ecology picked up from the ethological practice, and it helps to cast some light on the introduction of economical thinking in behavioural sciences.

Hypoxia hampers ATP production and threatens cell survival. Since cellular energetics tightly controls cell responses and fate, ATP levels and dynamics are of utmost importance. An integrated mathematical model of ATP synthesis by the mitochondrial oxidative phosphorylation/electron transfer chain system has been recently published (Beard, PLoS Comput Biol 1(4):e36, 2005). This model was validated under static conditions. To evaluate its performance under dynamical situations, we implemented and simulated it (Simulink®, The Mathworks). Inner membrane potential (ΔΨ) and [NADH] (feeding the electron (...) transfer chain) were used as indicators of mitochondrial function. Root mean squared error (rmse) was used to compare simulations and experiments (isolated cardiac mitochondria, Bose et al. J Biol Chem 278(40):39155–39165, 2003). Steady-state experimental data were reproduced within 2–6%. Model dynamics were evaluated under: (i) baseline, (ii) activation of NADH production, (iii) addition of ADP, (iv) addition of inorganic phosphate, (v) oxygen exhaustion. In all phases, except the last one, ΔΨ and [NADH] as well as oxygen consumption, were reproduced (within 10, 7 and 12%, respectively). Under anoxia, simulated ΔΨ markedly depolarized (no change in experiments). In conclusion, the model reproduces dynamic data as long as oxygen is present. Anticipated improvement by the inclusion of ATP consumption and explicit Krebs cycle are under evaluation. (shrink)
Substrate cycles are ubiquitous structures of the cellular metabolism (e.g. Krebs cycle, fatty acids -oxydation cycles, etc... ). Moiety-conserved cycles (e.g. adenine nucleotides and NADH/NAD, etc...) are also important.The role played by such cycles in the metabolism and its regulation is not clearly understood so far. However, it was shown that these cycles can generate multistationarity (bistability), irreversible transitions, enhancement of sensitivity, temporal oscillations and chaotic motions (Hervagault & Canu, 1987; Hervagault & Cimino, 1989; Reich & Sel'kov, 1981; Ricard (...) & Soulié, 1982). Fig. 1: Scheme of the open binary substrate cycle under study. The substrate S is converted into P with a net rate v2. Substrate P is converted in turn into S with a net rate v3. Step v2 is inhibited by excess of the substrate, S. In addition, the cycle operates under open conditions, that is zero-order input of S at rates \ga0(v1) and first order outputs of S and P at rates \gaS and \gaP(v4), respectively. (shrink)
We present diverse evidence for the claim of Pullum and Rawlins (2007) that expressives behave differently from descriptives in constructions that enforce a particular kind of semantic identity between elements. Our data are drawn from a wide variety of languages and construction types, and they point uniformly to a basic linguistic distinction between descriptive content and expressive content (Kaplan 1999; Potts 2007).
The Origin of Species by Charles Darwin is a landmark in the history of Biology. It laid down the foundations for the modern theory of evolution and influenced several areas of the Natural History as well as other fields of inquiry. The Origin of Species brings in the theory according to which Natural Selection has been the most important means, although not the only one, of modification and production of new species in Nature. The novelty of Darwin's way of arguing (...) in exposing and defending his theory can be seen in the methods, and explanatory patterns and strategies he creates and makes use of in the Origin of Species. These topics bear on those that have been fundamental to the Philosophy and History of Science, like the ones related to the role of theory and method, the ways of generating and applying concepts, and the patterns of explanaton in science. These questions, in turn, lead us te, think about the concept that is in the background of all discussions on science — the concept of scientific rationality. Usually, it is understood in terms of a cognitive faculty, an attitude, or a value. This way of understanding rattonality receives a richer treatment in Darwin's work, pointing to a network of multiple and interactive meanings. (shrink)
