In the Lambek calculus of order 2 we allow only sequents in which the depth of nesting of implications is limited to 2. We prove that the decision problem of provability in the calculus can be solved in time polynomial in the length of the sequent. A normal form for proofs of second order sequents is defined. It is shown that for every proof there is a normal form proof with the same axioms. With this normal form we can give (...) an algorithm that decides provability of sequents in polynomial time.

We present a new axiomatization of the non-associative Lambek calculus. We prove that it takes polynomial time to reduce any non-associative Lambek categorial grammar to an equivalent context-free grammar. Since it is possible to recognize a sentence generated by a context-free grammar in polynomial time, this proves that a sentence generated by any non-associative Lambek categorial grammar can be recognized in polynomial time.
This is the first exhaustive investigation of gradience in syntax, conceived of as grammatical indeterminacy. It looks at gradience in English word classes, phrases, clauses and constructions, and examines how it may be defined and differentiated. Professor Aarts addresses the tension between linguistic concepts and the continuous phenomena they describe by testing and categorizing grammatical vagueness and indeterminacy. He considers to what extent gradience is a grammatical phenomenon or a by-product of imperfect linguistic description, and makes a series of (...) linked proposals for its theoretical formalization.Bas Aarts draws on, and reviews, work in psychology, philosophy and language from Aristotle to Chomsky., and writes clearly on a fascinating and important aspect of language and cognition. His book will appeal to scholars and graduate students of language and syntactic theory in departments of linguistics, philosophy and cognitive science. (shrink)
Three experiments examined whether the mere priming of potential action effects enhances people’s feeling of causing these effects when they occur. In a computer task, participants and the computer independently moved a rapidly moving square on a display. Participants had to press a key, thereby stopping the movement. However, the participant or the computer could have caused the square to stop on the observed position, and accordingly, the stopped position of the square could be conceived of as the potential effect (...) resulting from participants’ action of pressing the stop key. The location of this position was primed or not just before participants had to stop the movement. Results showed that priming of the position enhanced experienced authorship of stopping the square. Additional experimentation demonstrated that this priming of agency was not mediated by the goal or intention to produce the effect. (shrink)
The results of an empirical study intoperceptions of the treatment of farm animals inthe Netherlands are presented. A qualitativeapproach, based on in-depth interviews withmeat livestock farmers and consumers was chosenin order to assess motivations behindperceptions and to gain insight into the waypeople deal with possible discrepancies betweentheir perceptions and their daily practices.Perceptions are analyzed with the help of aframe of reference, which consists ofvalues, norms, convictions, interests, andknowledge.
The conscious awareness of voluntary action is associated with systematic changes in time perception: The interval between actions and outcomes is experienced as compressed in time. Although this temporal binding is thought to result from voluntary movement and provides a window to the sense of agency, recent studies challenge this idea by demonstrating binding in involuntary movement. We offer a potential account for these findings by proposing that binding between involuntary actions and effects can occur when self-causation is implied. Participants (...) made temporal judgements concerning a key press and a tone, while they learned to consider themselves as the cause of the effect or not. Results showed that implied self-causation increased temporal binding. Since intrinsic motor cues of movement were absent, these results suggest that sensory evidence about the key press caused binding in retrospect and in line with the participant’s sense of being an agent.

Bothgroups show ambivalence as a result ofdiscrepancies between perceptions and behavior.Although the consumers share the impressionthat the living conditions of livestock animalsare far from optimal, most of them still buyand eat meat from the meat industry. Thefarmers believe the welfare of their animals isgood, but, as frequent defensive utterancesshow, they feel uncomfortable with expressed orunexpressed accusations of mistreating animals.The ways the respondents deal with thisambivalence were analysed by drawing ontheories of dissonance reduction and distancing devices.

It is generally assumed that storing predictive relations between two events in memory as bi-directional associations does not require conscious awareness of this relation, whereas the formation of unidirectional associations that capture the direction of the relation does. This study reports a set of experiments demonstrating that unidirectional associations can be formed even when awareness of the relation is actively prevented, if attention is “tuned” to process predictive relations. When participants engaged in predicting targets based on cues in an unrelated (...) task before the actual acquisition phase, unidirectional associations were formed during this acquisition phase even though E1 was presented subliminally. This suggests that although processing the relation between events may often be accompanied by awareness of this relation, awareness is not a prerequisite for the formation of unidirectional associations.

Recent research suggests that one can have the feeling of being the cause of an action’s outcome, even in the absence of a prior intention to act. That is, experienced self-agency over behavior increases when outcome representations are primed outside of awareness, prior to executing the action and observing the resulting outcome. Based on the notion that behavior can be represented at different levels, we propose that priming outcome representations is more likely to augment self-agency experiences when the primed representation (...) corresponds with a person’s behavior representation level. Three experiments, using different priming and self-agency tasks, both measuring and manipulating the level of behavior representation, confirmed this idea. Priming high level outcome representations enhanced experienced self-agency over behavior more strongly when behavior was represented at a higher level, rather than a lower level. Thus, priming effects on self-agency experiences critically depend on behavior representation level. (shrink)
Two experiments examined similarities and differences in the effects of consciously and unconsciously perceived rewards on the active maintenance of goal-relevant information. Participants could gain high and low monetary rewards for performance on a word span task. The reward value was presented supraliminally or subliminally at different stages during the task. In Experiment 1, rewards were presented before participants processed the target words. Enhanced performance was found in response to higher rewards, regardless whether they were presented supraliminally or subliminally. In (...) Experiment 2, rewards were presented after participants processed the target words, i.e., during maintenance. Performance increased in response to relatively high rewards when they were presented subliminally, but decreased when they were presented supraliminally. We conclude that both consciously and unconsciously perceived rewards boost resources supporting the maintenance of task-relevant information. Conscious processing of rewards can, however, heavily interfere with an ongoing maintenance process and impair performance. (shrink)
In a recent paper on realism and pragmatism published in this journal, Osmo Kivinen and Tero Piiroinen have been pleading for more methodological work in the philosophy of the social sciences—refining the conceptual tools of social scientists—and less philosophically ontological theories. Following this de-ontologizing approach, we scrutinize the debates on social explanation and contribute to the development of a pragmatic social science methodology. Analyzing four classic debates concerning explanation in the social sciences, we propose to shift the debate away from (...) (a) the ontologizing defenses of forms of social explanation, and (b) a winner-takes-all-approach. Instead, we advocate (c) a pragmatic approach towards social explanation, elaborating a rigorous framework for explanatory pluralism detached from the debates on social ontology. (shrink)
An agent may abandon an initiated action plan, although he doesnot acquire new information or encounter unforeseen obstacles.Such dynamic inconsistency can be to the agent'';s guaranteeddisadvantage, and there is a debate on how it should rationallybe avoided. The main contenders are the sophisticated andthe resolute approaches. I argue that this debate is misconceived,since both approaches rely on false assumptions about theperformability of action plans. The debate can be reformulated,so as to avoid these mistaken assumptions. I try to show that sucha (...) reformulation must rely on certain implausible claims. (shrink)
The present study investigated whether individual differences between psychologists in thinking styles are associated with accuracy in diagnostic classification. We asked novice and experienced clinicians to classify two clinical cases of clients with two co-occurring psychological disorders. No significant difference in diagnostic accuracy was found between the two groups, but when combining the data from novices and experienced psychologists accuracy was found to be negatively associated with certain decision making strategies and with a higher self-assessed ability and preference for a (...) rational thinking style. Our results underscore the idea that it might be fruitful to look for explanations of differences in the accuracy of diagnostic judgments in individual differences between psychologists (such as in thinking styles or decision making strategies used), rather than in experience level.

This paper describes a study of the effects of two acts of social intelligence, namely mimicry and social praise, when used by an artificial social agent. An experiment ( N = 50) is described which shows that social praise—positive feedback about the ongoing conversation—increases the perceived friendliness of a chat-robot. Mimicry—displaying matching behavior—enhances the perceived intelligence of the robot. We advice designers to incorporate both mimicry and social praise when their system needs to function as a social actor. Different ways (...) of implementing mimicry and praise by artificial social actors in an ambient persuasive scenario are discussed. (shrink)
The results of an empirical study into the perceptions of “hands-on” experts concerning the welfare of (non-human) animals in traveling circuses in the Netherlands are presented. A qualitative approach, based on in-depth conversations with trainers/performers, former trainers/performers, veterinarians, and an owner of an animal shelter, conveyed several patterns in the contextual construction of perceptions and the use of dissonance reduction strategies. Perceptions were analyzed with the help of the Symbolic Convergence Theory and the model of the frame of reference, consisting (...) of knowledge, convictions, values, norms, and interests. The study shows that the debate regarding animals in circuses in the Netherlands is centered on the level of welfare that is required; the importance of animal welfare is not disputed. Arguments that were used differed according to the respondents’ specific backgrounds and can be placed on a gradient ranging from the conviction that the welfare of animals in circuses is sufficiently warranted and both human and animal enjoy the performance (right end), to the conviction that animal welfare in circuses is negative, combined with the idea that the goal of entertaining people does not outweigh that (left end). The study confirms that perceptions reflect people’s contexts, though the variety in scopes suggests that the (inter)relations between people and their context are complex in nature. Evidence of cognitive dissonance was abundant. Coping strategies were found to be used more by respondents towards the right end of the gradient, suggesting that those respondents experience more ambivalence. This encountered pattern of association between position on the gradient and frequency of dissonance reduction strategies calls for further research on the type of ambivalent feelings experienced. The authors argue that, to come to an agreement about the welfare of animals in circuses, including the way this welfare should be guaranteed, stakeholders from different contexts need to engage in a dialogue in which a distance is taken from right/wrong-schemes and that starts from acceptance of dilemmas and ambiguity.

Material kept in the National Library of Finland shows that from 1963 until 1969 Erik Stenius (1911–1990) worked on a book on antinomies , having been invited by the Dutch logician Evert Beth (1908–1964) to contribute a monograph to the North-Holland series Studies in Logic and the Foundations of Mathematics . The book was never published, but the manuscript has been found, and it is the purpose of this note to report on this finding.
In this paper I develop a novel challenge for sceptical theists. I present a line of reasoning that appeals to sceptical theism to support scepticism about divine assertions. I claim that this reasoning is at least as plausible as one popular sceptical theistic strategy for responding to evidential arguments from evil. Thus, I seek to impale sceptical theists on the horns of a dilemma: concede that either sceptical theism implies scepticism about divine assertions, or the sceptical theistic strategy for responding (...) to evidential arguments from evil fails. An implication of is that sceptical theism is at odds with any religious tradition according to which there are certain claims that we can know to be true solely in virtue of the fact that God has told us that they are true. This result will render conceding unattractive to many sceptical theists. (shrink)
Jan Albert van Laar and Erik Krabbe’s paper “Splitting a difference of opinion” studies an important type of dialogue shift, namely that from a deliberation dialogue over action or policy options where critical and persuasive argumentation is exchanged about the rational acceptability of the policy options proposed by various parties, to a negotiation dialogue where agreement is reached by a series of compromises, or trade-offs, on the part of each side in the disagreement.
Erik Banks does several things in this slender yet substantial book on realistic empiricism (aka neutral monism). First, he encapsulates the main ideas of this tradition. While he goes into greater depth on some of these ideas than other introductions do, these pages are still accessible to nonspecialists. Second, he traces the the history of this tradition through the Austrian scientist, Ernst Mach, the American psychologist, William James, the British philosopher, Bertrand Russell, and others. These four chapters are a (...) valuable source for readers seeking to understand neutral monism in depth. Third, he develops his own version of neutral monism to deal with problems in the philosophies of mind and science. Most of my commentary will pertain to his own theory, which has some similar roots to my own. (shrink)
Erik Wielenberg’s new book Robust Ethics: The Metaphysics and Epistemology of Godless Normative Realism aims at defending a non-theistic of ‘robust normative realism’: the metaethical view that normative properties exist, and have four features: (1) objectivity, (2) non-naturalness, (3) irreducibility, and (4) causal inertness. In my review I criticize that Wielenberg does not address semantic issues which are crucial both to defending robust normative realism, and to assessing the empirical claims he makes. Moreover, and relatedly, I suggest that Wielenberg’s (...) main psychological and evolutionary claims may be less well-founded than suggested. Despite these worries, however, Robust Ethics is a highly valuable contribution to metaethics. Wielenberg’s writing is extremely accessible, engaging, witty, and clear, he develops various fascinating novel arguments, and skilfully links analytic reflections with the consideration of empirical data.

In their paper: “Learning of Predictive Relations Between Events Depends on Attention, Not on Awareness” Custers & Aarts demonstrate that when one is first exposed to a clear predictive relationship – a consequent predictive relationship will be represented as a unidirectional association in the percievers’ minds regardless of their awareness of that relationship. Furthermore, a conscious intention to learn the relationship leads to the formation of a bidirectional association. While these findings may prove to be a significant step in (...) understanding other forms of implicit learning such as implicit artificial grammar learning and implicit sequence learning and why they are affected by intentional learning; Custers & Aarts’ postulation that “top-down” regulation is at work here is debatable as their experimental manipulation can be understood as “bottom-up” activation of implicit learning processes.

In my response to Kevin Carnahan, I explain the concept of religion that I have been working with in my writings on the place of religious reasons in public political discourse. While acknowledging that religion is often privatized, my concern has been with religion as a way of life. It is religion so understood that raises the most serious issues concerning the role of religion in public discourse. In my response to Erik A. Anderson, I go beyond what I (...) have previously said about the role of religious reasons in public discourse. As an alternative to Rawlsian public reason, I argue that the essence of liberal democracy is that every citizen is to have equal political voice. I go on to consider what it is to exercise one’s equal political voice as a moral engagement. (shrink)
This comment on Erik Claes values his treatment of in-depth interviews to gain a better understanding of how volunteers make sense of their activities, but it questions the representativeness, meaningfulness and civicness of what is found. Meaning as deep personal commitment to an objective value is probably quite exceptional. The values and goals of Claes’s volunteers are deeply human and wide-ranging, but too ignorant of disagreement, power and politics to be called civic.

In Shaping Our Selves, Erik Parens offers both a personal history of bioethics and a cleverly clarifying lens to train on disputes in bioethics about emerging technologies. The question for readers is whether this lens, as useful as it is, leaves too much outside our field of vision. Parens, born in 1957, comes from the first wave of bioethics scholars—those of us who still mostly happened into bioethics as a field, before it was sufficiently well-established to be identified as (...) a career pathway. Bioethics enjoys a fascinating diversity of origin stories, and Parens’s is no exception. He began his studies at the University of Chicago’s pan-disciplinary Committee on Social Thought, one of a handful.. (shrink)
Erik Erikson's work in psychosocial developmental theory has made valuable contributions to the field of religious ethics on some very basic issues. This paper makes scattered elements of Erikson's explicit ethical perspective available in concise fashion for critical ethical reflection. It does this in such a way as to highlight the centrally important fact for religious ethics that implicitly operative in Erikson's view is a criterion of "self-transcendence" as definitive of mature personal (fully human, ethical) development.
The Dutch Roman Catholic theologian Erik Borgman, who developed a cultural theology, was appointed as a visiting professor at the liberal Protestant theological Mennonite Seminary in Amsterdam. In this article, his progressive Roman Catholic theology is compared to a liberal Protestant approach. The historical backgrounds of these different types of theology are expounded, all the way back to Aquinas and Scotus, in order to clarify their specific character for the sake of a better mutual understanding. Next, the convergence of (...) these two types of theology in the twentieth century is explained with reference to the philosophy of Heidegger. Finally, the difficulties posed by postmodern philosophies to both a progressive Roman Catholic theology and a liberal Protestant theology are shown. It is asserted that both types of theology claim that the insights of their particular tradition can be relevant beyond this tradition to modern and postmodern humans. (shrink)
Erik Schokkaert's note presents a very good summary of the theory of macrojustice and a very good list of the directions of research it points to. This is quite fitting since a research programme defines a paradigm, and he sees this proposal as a paradigm shift. This is also very appropriate since his own qualifications are the best for advancing fast in these research topics. I have only a very small number of qualifications to add to his presentation, but (...) I prefer to begin with emphasizing the most important issues. Two aspects can be seen as the most important: the de facto axiomatic derivation of the solution ELIE and its application on the one hand, and the present state of scholarly studies of the optimum or just distribution of income on the other hand. Let us enter by the second door (as opposed to what is done in the book Macrojustice). This will lead us to conclude with a more synthetic and broader view of the basic logic of the paradigms of justice and of the surprising recent history of their interpretations. (shrink)
The twentieth century has been described as the time of man’s discovery of himself; few have contributed more to this cause than Erik Erikson. _The Clinical Erik Erikson: A psychoanalytic method of engagement and activation_ highlights Erikson’s transforming contributions to the field of psychoanalysis and honors his legacy by providing unpublished clinical case illustrations of his actual psychotherapeutic work. The publication of case material—simple memorable fragments and clinical vignettes— brings the reader into Erikson’s consultation room, providing a portrait (...) of his clinical technique and demonstrating how he actually worked. Stephen Schlein, an authority on Erikson, presents an illuminating account of Erikson’s pioneering work through an exhaustive search of his early monographs on child psychoanalysis, clinical writings, psychotherapeutic case studies, and participation at case conferences at The Austen Riggs Center. Erikson’s writings reveal a psychoanalytic method of extraordinary richness that emphasizes essential ingredients of an interpersonal-relational clinical method and articulates interactional dimensions that have restorative potential. His vision focuses on the relationship, its powerful affects, and a belief that human beings have a potent capacity for real change. This book will be essential reading for psychoanalysts and psychoanalytic psychotherapists. (shrink)

In Radicalizing Enactivism, D. D. Hutto and E. Myin develop a theory of mind they call ‘Radical Enactive (or Embodied) Cognition’ (REC). They argue that extant enactivist and embodied theories of mind are, although pretty radical, not radical enough, because such theories buy into the representationalist doctrine that perceptual experience (along with other forms of ‘basic’ mentality) possesses representational content. REC denies this doctrine. It implies that perceptual experience lacks reference, truth conditions, accuracy conditions, or conditions of satisfaction. In this (...) review I summarise their anti-representationalist argument and show that it has at least three major weaknesses. (shrink)
