We humans and other animals continuously construct and main- tain our grasp of the world by using astonishingly small snippets of sensory information. Recent studies in nonlinear brain dynamics have shown how this occurs: brains imagine possible futures and seek and use sensory stimulation to select among them as guides for chosen actions. On the one hand the scientific explanation of the dynamics is inaccessible to most of us. On the other hand the philosophical foundation from which the sciences grew (...) is accessible through the work of one of its originators, Thomas Aquinas. The core concept of intention in Aquinas is the inviolable unity of mind, brain and body. All that we know we have constructed within ourselves from the unintelligible fragments of energy impacting our senses as we move our bodies through the world. This process of intention is transi- tive in the outward thrust of the body in search of desired future states; it is intransitive in the dynamic construction of predictions of the states in the sensory cortices by which we recognize suc- cess or failure in achievement. The process is phenomenologically experienced in the action-perception cycle. Enactment is through the serial creation of neurodynamic activity patterns in brains, by which the self of mind-brain-body comes to know the world first by shaping the self to an approximation of the sought-for input, and then by assimilating those shapes into knowledge and meaning. This conception of the self as closed, autonomous, and self- organizing, devised over 700 years ago and shelved by Descartes, Leibniz and Spinoza 300 years ago, is now re-emerging in philos- ophy and re-establishes the meaning of intention in its original sense. The core Aquinian concept of the unity of brain, body and soul/mind, which had been abandoned by mechanists and replaced by Brentano and Husserl using the duality inherent in representa- tionalism, has been revived by Heidegger and Merleau-Ponty, but in phenomenological terms that are opaque to neurscientists. In my experience there is no extant philosophical system than that of Aquinas that better fits with the new _ndings in nonlinear brain dynamics. Therefore, a detailed reading and transcription of basic terms is warranted, comparing in both directions the significance of key words across 700 years from medieval metaphysics to 21st century brain dynamics.

Many philosophical discussions hinge on the concept of knowability. For example, there is a blooming literature on the so-called paradox of knowability. How to understand this notion, however? In this paper, we examine several approaches to the notion: the naive approach to take knowability as the possibility to know, the counterfactual approach endorsed by Edgington (1985) and Schlöder (2019) , approaches based on the notion of a capacity or ability to know (Fara 2010, Humphreys 2011), and finally, (...) approaches that make use of the resources of dynamic epistemic logic (van Benthem 2004, Holliday 2017).

Non-invasive prenatal testing is at the forefront of prenatal screening. Current uses for NIPT include fetal sex determination and screening for chromosomal disorders such as trisomy 21. However, NIPT may be expanded to many different future applications. There are a potential host of ethical concerns around the expanding use of NIPT, as examined by the recent Nuffield Council report on the topic. It is important to examine what NIPT might be used for before these possibilities become consumer reality. There is (...) limited research exploring views of women on possible future uses of NIPT, particularly those of women who have undergone NIPT. In this study, we examined the views of women who undertook NIPT previously on the acceptability of and interest levels in using NIPT for a number of current and possible future applications. These included several medical conditions encompassing psychiatric, neurodevelopmental and adult-onset conditions as well as non-medical traits such as intelligence. One thousand women were invited to participate and 235 eligible surveys were received. Women generally reported an interest in using NIPT for medical conditions that severely impacted quality of life and with an onset earlier in life and stressed the importance of the accuracy of the test. Concerns were raised about the use of NIPT for non-medical traits. Respondents indicated that termination of pregnancy was not their only reason for testing, particularly in the case of sex. These results can further inform the ethical debate around the increasing integration of NIPT into healthcare systems. (shrink)

Epistemic logics based on the possible worlds semantics suffer from the problem of logical omniscience, whereby agents are described as knowing all logical consequences of what they know, including all tautologies. This problem is doubly challenging: on the one hand, agents should be treated as logically non-omniscient, and on the other hand, as moderately logically competent. Many responses to logical omniscience fail to meet this double challenge because the concepts of knowledge and reasoning are not properly separated. In this (...) paper, I present a dynamic logic of knowledge that models an agent’s epistemic state as it evolves over the course of reasoning. I show that the logic does not sacrifice logical competence on the altar of logical non- omniscience. (shrink)

The term “corporate transparency” is frequently used in scholarly discussions of business ethics and corporate social responsibility (CSR); however, it remains a volatile and imprecise term, often defined incompletely as “information disclosure” accomplished through standardized reporting. Based on the results of empirical studies of organizational behaviors, this paper identifies a new set of managerial practices based on the use of information and communication technologies (ICT) and particularly Internet-based tools. These practices are resulting in what can be termed “dynamic transparency.” (...) ICT allows for an informational environment characterized by two-way exchange between corporations and their stakeholders, which fosters a more collaborative marketplace. It is proposed that such dynamic information sharing, conducted by means of ICT, drives organizations to display greater openness and accountability, and more transparent operations, which benefit both the corporations and their constituents. One of the most important outcomes that will accrue to consumers and other individuals is the “right to know,” especially about corporate strategies and activities that might directly affect their quality of life. This paper demonstrates that dynamic transparency is more desirable and more effective than the more common “static transparency” where firms’ information disclosure is one-way, usually in response to government regulation. We present three ethical arguments to justify the implementation by business firms of dynamic transparency and demonstrate that their doing so is related to CSR and to augment and complement stakeholder engagement and dialogue. The paper concludes with a summary of the possible limits to and the problems involved in the implementation of dynamic transparency for corporations, and suggests some strategies to counter them.

Many philosophers hold there are genuine cases of culpable ignorance. This paper argues that there are conditions that can render knowledge epistemically culpable too. First, we contrast culpable ignorance with morally culpable knowledge. Second, we examine the nature of epistemically culpable knowledge using a key example. We then highlight empirical support for the claim that there are real-world conditions that make epistemically culpable knowledge possible. Next, we survey three kinds of epistemic culpability fostered by culpable knowledge. Finally, we address the (...) benefits objection and argue that it fails. (shrink)

We take a logical approach to threshold models, used to study the diffusion of e.g. new technologies or behaviors in social net-works. In short, threshold models consist of a network graph of agents connected by a social relationship and a threshold to adopt a possibly cascading behavior. Agents adopt new behavior when the proportion of their neighbors who have already adopted it meets the threshold. Under this adoption policy, threshold models develop dynamically with a guaranteed fixed point. We construct a (...) minimal dynamic propositional logic to describe the threshold dynamics and show that the logic is sound and complete. We then extend this framework with an epistemic dimension and investigate how information about more distant neighbors’ behaviors allows agents to anticipate changes in behavior of their closer neighbors. It is shown that this epistemic prediction dynamics is equivalent to the non-epistemic threshold model dynamics if and only if agents know exactly their neighbors’ behavior. We further show results regarding fixed points and convergence speed,and provide a partial set of reduction laws, venues for further research, and graphical representations of the dynamics. (shrink)

Though we have access to a wealth of information, the main issue is always how to process the available information. How to make sense of all we observe and know. Just like the English alphabet: we know there are 26 letters but unless we put these letters together in a meaningful way, they convey no information. There are infinitely many ways of putting these letters together. Only a small number of those make sense. Only some of those convey (...) exactly what we wish to convey though the message may be interpreted differently by different individuals. That same issue comes up with information: how can we process the information we have? How can we infer and reason under conditions of incomplete observed information? In his seminal book on the philosophy of information, Floridi (2011a) raises a number of open questions. I discuss here one of these questions. That question is how to process information. To do so, I take the more realistic view that information is always limited, incomplete and possibly noisy. I define types of information, relate it to Floridi’s definitions and discuss a basic formulation for processing information under a unified framework. I relate it to some of the basic concepts discussed in the book. (shrink)

According to the Relevant Alternatives (RA) Theory of knowledge, knowing that something is the case involves ruling out (only) the relevant alternatives. The conception of knowledge in epistemic logic also involves the elimination of possibilities, but without an explicit distinction, among the possibilities consistent with an agent’s information, between those relevant possibilities that an agent must rule out in order to know and those remote, far-fetched or otherwise irrelevant possibilities. In this article, I propose formalizations of two versions of (...) the RA theory. Doing so clarifies a famous debate in epistemology, pitting Fred Dretske against David Lewis, about whether the RA theorist should accept the principle that knowledge is closed under known implication, familiar as the K axiom in epistemic logic. Dretske’s case against closure under known implication leads to a study of other closure principles, while Lewis’s defense of closure by appeal to the claimed context sensitivity of knowledge attributions leads to a study of the dynamics of context. Having followed the first lead at length in other work, here I focus more on the second, especially on logical issues associated with developing a dynamic epistemic logic of context change over models for the RA theory.

The major part of this paper is devoted to the task of showing that Husserl's account of knowledge and truth in terms of a synthesis of fulfilment falls prey neither to a form of “metaphysics of presence” nor to a “myth of interiority” or mentalism. Husserl's presentation of the desire to know, his awareness of irreducible forms of absence at the heart of the intuitive presence of the object of knowledge and his formulation of general rules concerning the possible (...) accomplishment of a synthesis of fulfilment are therefore carefully examined. Special attention is also given to the fact that the determination of knowledge and truth provided by the Sixth Logical Investigation rests on an account of an original interweaving between the thing, consciousness, and language. Unlike in Husserl's earlier and later works, no attempt is thereby made to subordinate any of these three elements involved in all knowledge to one of the others. (shrink)

The focus of this article is the question whether the notion of being in a position to know is closed under modus ponens. The question is answered negatively.

Time is a fundamental dimension of consciousness. Many studies of the “sense of agency” have investigated whether we attribute actions to ourselves based on a conscious experience of intention occurring prior to action, or based on a reconstruction after the action itself has occurred. Here, we ask the same question about a lower level aspect of action experience, namely awareness of the detailed spatial form of a simple movement. Subjects reached for a target, which unpredictably jumped to the side on (...) some trials. Participants expressed their expectancy of a target shift during the upcoming movement, pointed at the target as quickly and accurately as possible before returning to the start posiment to the target shift if required and reproduced the spatial path of the movement they had just made, as accurately as possible, to give an indication of their awareness of the pointing movement. We analysed the spatial disparity between the initial and the reproduced movements on those with a target shift. A negative disparity value, or undershoot, suggests that motor awareness merely reflects a sluggish record of coordinated motor performance, while a positive value, or overshoot, suggests that participants’ intention to point to the shifting target contributes more to their awareness of action than their actual pointing movement. Undershoot and overshoot thus measure the reconstructive and the preconstuctive aspects of action awareness, respectively. We found that trials on which subjects strongly expected a target shift showed greater overshoot and less undershoot than trials with lower expectancy. Conscious expectancy therefore strongly influences the experience of the detailed motor parameters of our actions. Further, a delay inserted either between the expectancy judgement and the pointing movement, or between the pointing movement and the reproduction of the movement, had no effect on visuomotor adjustment but strongly influenced action awareness. Delays during either interval boosted undershoots, suggesting increased reliance on a time-limited sensory memory for action. The experience of action is thus strongly influenced by prior thoughts and expectations, but only over a short time period. Thus, awareness of our actions is a dynamic and relatively flexible mixture of what we intend to do, and what our motor system actually does. (shrink)

The concept of being in a position to know is an increasingly popular member of the epistemologist’s toolkit. Some have used it as a basis for an account of propositional justification. Others, following Timothy Williamson, have used it as a vehicle for articulating interesting luminosity and anti-luminosity theses. It is tempting to think that while knowledge itself does not obey any closure principles, being in a position to know does. For example, if one knows both p and ‘If (...) p then q’, but one dies or gets distracted before being able to perform a modus ponens on these items of knowledge and for that reason one does not know q, one is still plausibly in a position to know q. It is also tempting to suppose that, while one does not know all logical truths, one is nevertheless in a position to know every logical truth. Putting these temptations together, we get the view that being in a position to know has a normal modal logic. A recent literature has begun to investigate whether it is a good idea to give in to these twin temptations—in particular the first one. That literature assumes very naturally that one is in a position to know everything one knows and that one is not in a position to know things that one cannot know. It has succeeded in showing that, given the modest closure condition that knowledge is closed under conjunction elimination, being a position to know cannot satisfy the so-called K axiom of normal modal logics. In this paper, we explore the question of the normality of the logic of being in a position to know in a more far-reaching and systematic way. Assuming that being in a position to know entails the possibility of knowing and that knowing entails being in a position to know, we can demonstrate radical failures of normality without assuming any closure principles at all for knowledge. Moreover, the failure of normality cannot be laid at the door of the K axiom for knowledge, since the standard principle NEC of necessitation also fails for being in a position to know. After laying out and explaining our results, we briefly survey the coherent options that remain. (shrink)

We found that trials on which subjects strongly expected a target shift showed greater overshoot and less undershoot than trials with lower expectancy. Conscious expectancy therefore strongly influences the experience of the detailed motor parameters of our actions.

Preference formation and choice are dynamic cognitive processes arising from interactions between decision-makers and their immediate choice environment. This thesis examines how preferences and decisions are played out in visual attention, captured by eye-movements, as well as in group contexts. Papers I-II make use of the Choice Blindness paradigm. Paper I compares participants’ eye movements and pupil dilation over the course of a trial when participants detect and fail to detect the false feedback concerning their choices. Results indicate objective (...) markers of detection with important implications for questions concerning possible demand effect or cognitive dissonance explanations of choice blindness. Paper II examines another aspect of the choice environment, namely, the social context. Choice blindness is demonstrated in small groups for the first time. It is shown that preferential change can be induced in dyads by manipulating the group’s beliefs about their choices, thus extending the preference change through choice effects beyond individuals for the first time. Paper III examines how visual attention differentially supports both decision and memory processes depending on the amount of task-relevant information available to participants. Participants’ performance and visual attention dynamics was found to vary depending on the amount of information available to them, and the results indicate that decision outcomes are heavily influenced by encoding prior to traditional choice phases used in decision research. Papers IV-VII concern decision-making in the moral domain. Paper IV investigates visual attention when participants choose between difficult moral dilemmas, showing asymmetries in how participants distribute their attention depending on making utilitarian or deontological choices. Paper V introduces a novel paradigm for influencing decision based manipulating the timing of decision by measuring the direction of gaze while the participant deliberates. Using this method participants’ moral decisions were biased without their knowledge to a randomly chosen alternative. This shows that moral decision and visual attention are highly coupled and that by simply knowing where someone is looking it is possible to influence their decision process. Papers VI&VII build on the links between gaze direction and moral choice and present the first computational decision models based on eye gaze applicable to the moral domain. Paper VI for choices between abstract principles and Paper VII for donations to charitable organizations. Together the papers advance novel methodological solutions to understanding preferences and decisions across a number of domains, both highlighting the important contributions of social and sensorimotor interactions to the content of our decisions as they develop over time, as well as demonstrating how decisions can be influenced by leveraging those interactions.

Well before the current age of discourse, deconstruction, and multiculturalism, Richard McKeon propounded a philosophy of pluralism showing how "facts" and "values" are dependent on diverse ways of reading texts. This book is a transcription of an entire course, including both lectures and student discussions, taught by McKeon. As such, it provides an exciting introduction to McKeon's conception of pluralism, a central aspect of neo-Pragmatism, while demonstrating how pluralism works in a classroom setting. In his lectures, McKeon outlines the entire (...) history of Western thinking on the sciences. Treating the central concepts of motion, space, time, and cause, he traces modern intellectual debates back to the ancient Greeks, notably Plato, Aristotle, Democritus, and the Sophists. As he brings the story of Western science up to the twentieth century, he uses his fabled semantic schema (reproduced here for the first time) to uncover new ideas and observations about cosmology, mechanics, dynamics, and other aspects of physical science. Illustrating the broad historical sweep of the lectures are a series of discussions which give detail to the course's intellectual framework. These discussions of Plato, Aristotle, Galileo, Newton, and Maxwell are perhaps the first published rendition of a philosopher in literal dialogue with his students. Led by McKeon's pointed questioning, the discussions reveal the difficulties and possibilities of learning to engage in serious intellectual communication. (shrink)

This undergraduate textbook introduces some fundamental issues in philosophy of science for students of philosophy and science students. The book is divided into two parts. Part 1 deals with knowledge and values. Chap. 1 presents the classical conception of knowledge as initiated by the ancient Greeks and elaborated during the development of science, introducing the central concepts of truth, belief and justification. Aspects of the quest for objectivity are taken up in the following two chapters. Moral issues are broached in (...) Chap. 4, which discusses some aspects of the use and abuse of science, taking up the responsibilities of scientists in properly conducting their business and decision-makers in their concerns with the import of science for society. Part 2 contrasts the view of scientific progress as the rejecting of old hypotheses and theories and replacing them with new ones, represented by Karl Popper, with the conception of progress as accumulating knowledge, saving as much as possible from older theories, represented by Pierre Duhem. A concluding chapter defends the natural attitude of taking the theories of modern science to be literally true, i.e. realism, in the face of arguments drawn partly from the history of scientific progress in criticism of this stance.

The article shows how, by changing the formulations of habitual premises and critical questions for pre­sumptive argumentation schemes, one can evaluate an argument even before its type has become known. The argument from position to know is used to justify the possibility of detecting types of classical pre­sumptive schemes when we take into account the type of speech act used to implement them, and the speaker and listener’s awareness of each other’s propositional attitudes. The types of argument from (...) posi­tion to know are distinguished with respect to their epistemic and illocutionary variety. Following Austin one of these types can be considered a performative argument from position to know. The article describes the principles of its usage and outlines the evaluation procedure. (shrink)

Security properties naturally combine temporal aspects of protocols with aspects of knowledge of the agents. Since BAN-logic, there have been several initiatives and attempts to incorpórate epistemics into the analysis of security protocols. In this paper, we give an overview of work in the field and present it in a unified perspective, with comparisons on technical subtleties that have been employed in different approaches. Also, we study to which degree the use of epistemics is essential for the analysis of security (...) protocols. We look for formal conditions under which knowledge modalities can bring extra expressive power to pure temporal languages. On the other hand, we discuss the cost of the epistemic operators in terms of model checking complexity. (shrink)

Coordination problems, problems in which each agent's expected utility depends upon what other agents do, pose a problem for act utilitarianism. When the agents are act utilitarians and know of each other that they are so, they seem unable to achieve optimal outcomes in certain coordination problems. I examine various ways the act utilitarian might attempt to solve this problem, where act utilitarianism is interpreted within the framework of subjective expected utility theory. In particular, a new method for computing (...) expected utility,dynamic deliberation, deserves examination as a possible act utilitarian solution to coordination problems. I argue that even dynamic deliberation fails to give the act utilitarian what he needs in coordination problems, and that the failure of act utilitarianism for such problems suggests the need for an alternative theory of moral choice along rule utilitarian lines.

This chapter argues that it is possible to identify, in the coming to be of knowledge, the three elements that Aristotle says are involved in any kind of coming to be whatsoever (viz., matter, form, and the generated composite object). Specifically, it is argued that in this schema the passive intellect (pathetikos nous) corresponds to the matter, the active intellect (poetikos nous) corresponds to the form, and the composite object corresponds to the mind as actually knowing.

I endorse five central themes of Charlotte Witt's Social Goodness: the pervasiveness and irreducibility of social roles and norms; normative externalism; the artisanal model; a richer social ontology; and the possible critical transformation of social norms from within. I reframe these themes within the biological account of the evolution and development of human ways of life in Joseph Rouse's Social Practices as Biological Niche Construction. Witt's social analysis attends to human bodies as loci of artisanal skills and social salience as (...) gendered, sexed, and raced, but not to bodies as vulnerable, dependent organisms in social environments. A broader, biological conception of normativity shifts from Witt's focus on social roles and norms to the dynamics of social practices as shaping people's developmental environments. This more complex account of social dynamics enriches Witt's conservative account of how practices are transmitted and sustained. It thereby surpasses limitations in her account of how hierarchical social norms can be both obligating and open to critical challenge from within. It does so in three ways: by emphasizing normative conflicts within practices, by shifting from individual know-how to discursive practices as loci of artisanal authority, and by an account of power relations as intertwined with biosocial normativity.

Reasoning about what other people know is an important cognitive ability, known as epistemic reasoning, which has fascinated psychologists, economists, and logicians. In this paper, we propose a computational model of humans’ epistemic reasoning, including higher-order epistemic reasoning—reasoning about what one person knows about another person’s knowledge—that we test in an experiment using a deductive card game called “Aces and Eights”. Our starting point is the model of perfect higher-order epistemic reasoners given by the framework of dynamic epistemic (...) logic. We modify this idealized model with bounds on the level of feasible epistemic reasoning and stochastic update of a player’s space of possibilities in response to new information. These modifications are crucial for explaining the variation in human performance across different participants and different games in the experiment. Our results demonstrate how research on epistemic logic and cognitive models can inform each other. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Roger A. Shiner GETTING TO KNOW YOU IN pursuits OF happiness, Stanley Cavell attempts to establish the existence of a previously unrecognized genre of film — "comedies of remarriage " — which both includes and is defined by such movies as Adam's Rib, Bringing Up Baby, and TL· Philadelphia Story. l By "marriage" and "remarriage " is meant a certain kind of enduring emotional intimacy with which we (...) as adult men and women will be involved, an intimacy which is an integral part of the human form of life and whose relationship to an institutionally supported legal status in our culture is not one of identity. The same is true for the concept of "divorce" in this context. Using some of Cavell's interpretive ideas as a starting point, I shall seek to present the genre of remarriage as a figure for the profoundest relationships of epistemology and metaphysics — the relationship of the knower to the world which is known and the relationship of the individual to die other individuals widi whom society is shared. Specifically, divorce and remarriage as part of human life are to be seen as figures for separation and kinship, avoidance and acknowledgement in the philosophical sense of those terms.2 My discussion proceeds on several levels. There is film criticism, which attempts to find significance in certain movies. There is an examination of values, which presents a certain view ofmarriage as a human relationship. There is some metaphysics, which addresses certain traditional philosophical problems in a nontraditional way. And finally there is metaphilosophy, which attempts to present a different way ofhow to ask, and how to acknowledge as being answered, the great questions of philosophy. Only the latter two projects could be described as "philosophical" in a conventional sense. Yet, as Arthur Danto has rightly remarked,3 Cavell in Pursuits ofHappiness seems to be trying to suggest that to blur deliberately the distinction between criticism and philosophy is to show something 80 Roger A. Shiner81 important about philosophy (and thus criticism as well). If this essay in some small way is thought to show something similar, I shall be pleased. Cavell begins his chapter on It Happened One Night with some ruminations on Locke, Hume, Kant, and the idea of the limitations of human reason. Kant undertakes to show, Cavell claims (PH, pp. 75-76), that our position as human knowers is both better and worse than the Empiricists suggest. It is worse, because even if we pressed human knowledge to its Kantian limits, we would know more but not enough to fulfill the philosopher 's dream. It is better, because the very facts that are limitations of human knowledge are also the necessary conditions ofknowledge as such and to know those conditions clearly is enormously to increase human knowledge. The link between the limitations ofhuman knowledge and the comedies of remarriage is forged by the thought (CR, p. 74) that the capacity to relate oneself to the world by knowledge and the capacity to relate oneselfto others by marriage are both constitutive ofhuman society. Human community is based in part on the fact that there are limitations as to what each of us as individual knowers can know. We need each other's knowledge. If one of us were per impossibile to transcend the limitations of human knowledge, he would know, as it were, what God knows and thus have the power that God has. But the existence of these limitations reveals something deep about human knowledge, something which traditional theory of knowledge rejects, namely that it is human. Human knowledge is limited, but it is genuine. It rests on no surer a foundation than human community, but human beings are a community. We need each other, but we are there for each other. Community, and therefore knowledge, does not need to be achieved: it exists.4 Similarly, the conventions in society limiting the capacity to relate oneselfto others by marriage (one at a time, and only under protest not one forever) reveal something deep about the nature of marriage. The mutuality of the intimacy ofmarriage is possible only in conjunction with the exclusiveness of marriage. Only by turning away from all others can the taking into... (shrink)

The traditional possible-worlds model of belief describes agents as ‘logically omniscient’ in the sense that they believe all logical consequences of what they believe, including all logical truths. This is widely considered a problem if we want to reason about the epistemic lives of non-ideal agents who—much like ordinary human beings—are logically competent, but not logically omniscient. A popular strategy for avoiding logical omniscience centers around the use of impossible worlds: worlds that, in one way or another, violate the laws (...) of logic. In this paper, we argue that existing impossible-worlds models of belief fail to describe agents who are both logically non-omniscient and logically competent. To model such agents, we argue, we need to ‘dynamize’ the impossible-worlds framework in a way that allows us to capture not only what agents believe, but also what they are able to infer from what they believe. In light of this diagnosis, we go on to develop the formal details of a dynamic impossible-worlds framework, and show that it successfully models agents who are both logically non-omniscient and logically competent.

Though the authors of this commentary have deep felt doubts about the fruitfulness of Björkman and Hansson’s analysis of bodily rights, they do not doubt their capacity to develop both creative and provocative thoughtsIt is always welcoming to be confronted with thoughts that, even though one wholeheartedly disagrees with them, have the effect of stimulating one’s own reflections on matters, which without such confrontations, would have been less distinct, less critical—and we would gladly admit, less polemical. Thus it is thanks (...) to Barbro Björkman and Sven Ove Hansson’s article, “Bodily rights and property rights”, that we have been able to set our present course into these murky waters. The issue they want to address is by no means of a kind that lends itself easily to theoretical speculation. This has, perhaps, as much to do with the inherent intricacy of the issue itself as with the controversy it has managed to arouse. The issue is: is it possible to have ownership over one’s own body—that is, is it appropriate to treat the body and its components as property? What are the implications of conceptualising the body and its parts in terms of property? Should one, as a general rule, be able to sell and buy human biological material? If so, who should be allowed to buy and sell it? Does the sale or donation of one’s own bodily parts imply a transfer of ownership rights to the buyer or receiver, or is it rather that ownership of human bodily parts can only be acquired after the material has been, say, manipulated in a laboratory?Contrary to Björkman and Hansson, who see “the primary normative issue” to be “what combination of rights a person should have to a particular item of biological material”, we believe that their decision to construe ….

Tense operators in effect algebras play a key role for the representation of the dynamics of formally described physical systems. For this, it is important to know how to construct them on a given effect algebra \( E\) and how to compute all possible pairs of tense operators on \( E\) . However, we firstly need to derive a time frame which enables these constructions and computations. Hence, we usually apply a suitable set of states of the effect algebra (...) \( E\) in question. To approximate physical reality in quantum mechanics, we use only the so-called Jauch–Piron states on \( E\) in our paper. To realize our constructions, we are restricted on lattice effect algebras only. (shrink)

In Alzheimer's disease (AD), pathological processes start in the brain long before clinical dementia. Biomarkers reflecting brain alterations may therefore indicate disease at an early stage, enabling early diagnosis. This raises several ethical questions and the potential benefits of early diagnosis must be weighted against possible disadvantages. Currently, there are few strong arguments favouring early diagnosis, due to the lack of disease modifying therapy. Also, available diagnostic methods risk erroneous classifications, with potentially grave consequences. However, a possible benefit of early (...) diagnosis even without disease modifying therapy is that it may enable early decision making when patients still have full decision competence, avoiding problems of hypothetical consents. It may also help identifying patients with cognitive dysfunction secondary to other diseases that may be responsive to treatment already today. (shrink)

The paper explores the intricate interplay of two parallel developments: on the one hand, the Socratic turn in epistemology with its shifting focus on information retrieval, evidence-based reasoning, and the cognitive relevance of questions; and the advance of dynamic epistemic logic with its accent on knowledge-acquisition. Both are relevant for any realistic model of knowledge which pays due attention to learning. It is argued that the formal models are still wanting in some key respects, but the development of alternative (...) and mutually complementing logical systems marks a promising trend for re-establishing the close links between epistemology and epistemic logic.

l. THE GENERAL PROBLEM OF EPISTEMOLOGY There is a philosophical issue that surely precedes all other possible questions. It concerns the very possibility of our thinking about some thing to some purpose. Short of this no philosophy, theory or research would be possible. But it is not immediately clear that we are assured that what purports to be effective thought, and cognition is such in reality. What guarantee is there for instance that when one is under the impression that (...) one is thinking that "the cat is on the mat" it is in fact the case that one is thinking this? One could not be thinking at all, only having a misleading mystic experience. And then even if one was thinking, one might not be really thinking of the cat being on the mat, but only that one wishes there was a cat, and wonders whether if there was it would be on the mat, and yet the subjective impression was that one was thinking: "The cat is on the mat". Then one might in some way try to think 'the cat is on the mat. ' yet be mistaken in that there aren't any material objects at all, and all one does is to inventory god's perceptions. And so on, and so on! These are of course the kind of problem that the layman habitually views with disdainful alarm. (shrink)

What is the difference between knowing someone and acknowledging them? Is it possible to want to be acknowledged while remaining unknown? And if one’s desire to know another person is too consuming, can this foreclose the possibility of acknowledgment? Cavell argues that we sometimes avoid the ethical problem of acknowledgment by (mis)conceiving our relations with others in terms of knowledge and that this epistemic misconception can actually amount to a form of ethical harm. I show that Polanski’s Chinatown (...) helps us understand the difference between knowing and acknowledging and that Cavell’s concepts help us better appreciate Chinatown. (shrink)

Context: Philosophical and - more recently - empirical approaches to the study of mind have recognized the research of lived experience as crucial for the understanding of their subject matter. Such research is faced with self-referentiality: every attempt at examining the experience seems to change the experience in question. This so-called “excavation fallacy” has been taken by many to undermine the possibility of first-person inquiry as a form of scientific practice. Problem: What is the epistemic character and value of (...) reflectively acquired phenomenological data? Can the study of experience, despite the excavation fallacy, rely on the act of reflection on lived experience and make sense and use of its results? Method: Through a philosophical discourse, informed by empirical first-person inquiry, we explore the experiential structure of the act of reflection and the formation of the corresponding belief about past experience. Results: We present a provisional first-person model of the experiential dynamics of retrospective reflection, in which the reflective act is characterized as enaction of belief about past experience that co-determines - rather than distorts - its results. From a constructivist perspective on the inevitable interdependence between the act of observing and the observed, the excavation “fallacy” is recognized as an intrinsic characteristic of reflection. Reflection is described as an iterative, self-referential process, guided by a context- and subject-specific horizon of expectations. Implications: Knowing the characteristics of the formation of beliefs about experience is essential for understanding first-person data and for the possibility of their acquisition and use in scientific practice, particularly in the context of second-person approaches to the study of experience. Constructivist content: We relate the proposed understanding of reflection to constructivist epistemology and argue that constructivism provides an epistemological foundation for the empirical study of experience more suitable than the traditional epistemological objectivism of cognitive science. We suggest that the constructive nature of the process of reflection calls for a collaboration between the fields of constructivism, phenomenology, and first-person research, and points towards the potential for their mutual enrichment.

Darwin's theory of evolution brought to an end the static view of nature. It was no longer possible to think of species as immortal, with secure places in nature. Fluctuation of population could no longer be thought of as occurring within definite limits which had been set at the time of creation. Nor was it any longer possible to generalize from the differential reproductive potentials, or from a few cases of mutualism between species, that everything in nature was “fitted to (...) produce general ends, and reciprocal uses.” 134 The appeal to “design” could no longer be substituted for answers to questions concerning animal demography. Instead, the dynamics of a population had to be viewed as the outcome of species' struggle against animate and inanimate factors in the environment. Both the members of a species and the environmental factors tend to vary randomly, and therefore neither evolution nor population dynamics could be fully understood alone. For this reason Darwin's linking of the two subjects was inevitable and not merely an historical accident. Since Darwin had shown that no automatic equilibrium existed, he demonstrated the importance of closer study of the causes of population dynamics and extinction. He also indicated that an understanding of population depends upon the development of a broad knowledge in ecology.Viewed from another direction, Darwin's work ended the early modern era of population studies by clarifying three interrelated problems which were important for understanding population: extinction, distribution, and the nature of species. The components of his answer had been discussed in the eighteenth century, but there had not existed enough evidence for the completion of the revolution in thought which had then begun. At the beginning of the nineteenth century, Playfair found the evidence for extinction conclusive, and, in spite of Lamarck, Curvier convinced the scientific world that there could no longer be any doubt about it. This was a step the importance of which, with his limited knowledge of biogeography and population, Cuvier could not have fully realized. Lamarck attempted, with his evolutionary theory, to circumvent the necessity for admitting extinction, but he overestimated the adaptability of organisms and in doing so he underestimated the importance of competition and the whole field of ecology. On the other hand, he was not willing to let questions such as the origin of species remain taboo to science. The origin of species was a biogeographical as well as a paleontological question. Humboldt correlated environment with the distribution of species and conveyed the impression that plant communities are subject to change. De Candolle, following the lead of Linnaeus and Humboldt, emphasized the ecological aspects of biogeography, not only the importance of habitat and range, clearly showing the ecological effects of competition. The entomologists Kirby and Spence took a faltering step toward understanding the relationship between population and ecological role, but they fell short of any significant new conclusions. Neither they nor Swainson could fully comprehend the new perspective of De Candolle.Lyell was able to bring together the evidence from these three lines of investigation and weave them into an important synthesis that almost accomplished that Darwin later did. Although opposing Lamarck's theory of evolution, Lyell had a dynamic view of ecology. He realized that population dynamics offered an important key to the understanding of biogeography. Since he knew that species become extinct, he investigated closely the factors which could either preserve or extinguish species. While explaining these factors, he described the interrelationships of species in greater detail than had ever been done before. Forbes continued to develop Lyell's ecological concepts, and his first-hand field experience enabled him to describe biotic communities more concretely than Lyell had.Having the advantages of Lyell's understanding and his own experience from a global voyage, Darwin could take the final step from the static to the dynamic concept of life. He had seen populations fluctuating and also fossil species in South America, and on the Galapagos Islands he had encountered a biogeographical problem that could not be credibly solved without the idea of evolution. However, the bare idea of evolution did not fully answer his questions. He sought physiological causes of extinction before he read Malthus and realized that De Candolle and Lyell had correctly emphasized the importance of competition. Darwin found that, in order to understand evolution, he needed to improve his understanding of ecology. He wanted to know when populations were most easily decimated, how extensive were competition and cooperation, what effects parasites have upon populations, and what changes occur in biotic communities when a species is either added or subtracted. He contributed to some extent to answering these questions. Though there remained much for others to do, there was now a new and more secure theoretical framework within which later studies could be interpreted. As Ernst Mayr has observed, Darwin's “consistent thinking in terms of population has had an impact on biological theory and practice which is second only to his sponsorship of natural selection as the mechanism of evolution.” 135.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 11.4 (2004) 299-301 [Access article in PDF] The Right Not to Know: A Challenge for Accurate Self-Assessment Ruth F. Chadwick Anderson and Lux present a very interesting and thought-provoking argument for the view that accurate self-assessment is a requirement for personal autonomy. What I want to suggest is that although this may be helpful in the context with which these authors are primarily concerned, (...) namely psychiatry and brain dysfunction, it is of less value to an account of autonomy more widely construed. I want to look at a possible counterexample, taken from another area of medicine, namely genetics.Toward the end of their article Anderson and Lux consider three objections to their position. I shall not discuss them all. My concern is with the third, that inaccurate self-assessment sometimes promotes autonomy, because knowing the truth about one's weaknesses is sometimes very debilitating. It is commonly argued that "you can if you think you can" and vice versa. As they point out, there are some complex issues involved here, in that if the result of the positive thinking is the ability to do the thing in question, then how can the self-assessment be deemed to have been inaccurate in the first place? They go on, however, to say that "it is unclear that inflated self-assessments yield benefits in contexts where what is required is not just effort but competence" (290).Now it has been argued, by some, in the context of genetics, that the proper understanding of autonomy may imply a "right not to know" facts about oneself. In other words, this is not just a matter of accurate or inaccurate assessment of the relevant facts about oneself; rather, what may be involved is a deliberate decision not to have access to facts that may be relevant to that assessment. There are clearly cases in which genetic information appears to be pertinent to an accurate self-assessment, as the following example suggests. Suppose there is information "available", through genetic testing, that would affect one's chances of having children, or of having children without a particular genetic disorder, and, knowing that such information is available, a couple decides not to avail themselves of this. This is clearly an inaccurate self-assessment, but is their autonomy compromised?It might be thought that the reasons for this decision not to know could be relevant. If they have no family history of any particular genetic disorder, it could be regarded as subjectively reasonable to decline such testing as might be offered. Anderson and Lux, however, argue that whether or not a self-assessment is accurate depends on externalities. In other words, A's self-assessment is not to be assessed as accurate, or [End Page 299] not, according to what it is subjectively reasonable to believe; it has to be measured against the facts. The more that the possibilities of genetic testing increase, the more that "facts" of this nature will be available, including in the context of psychiatry.It might be objected that genetic information is not the type of information that is relevant in this context. In so far as it is predictive and probabilistic it is, arguably, different from the type of diagnostic information involved in the cases discussed by Anderson and Lux. It is not the place here, however, to discuss in general terms the thesis of "genetic exceptionalism" with regard to medical information. The important point is refusal of access to information that may be relevant to an accurate self-assessment. Historically, people have been mistaken in their self-assessment because of lack of information—for example, lack of understanding of facts about the reproduction process has led individuals automatically to blame the woman partner of a couple for infertility. And, as Anderson and Lux rightly point out, being autonomous is compatible with making mistakes, and indeed requires the freedom to make mistakes, it would look rather different if a person continued to hold this without any attempt to avail himself of the relevant—and now available—information...

Defends an account of mathematical knowledge in which mathematical knowledge is a kind of modal knowledge. Leng argues that nominalists should take mathematical knowledge to consist in knowledge of the consistency of mathematical axiomatic systems, and knowledge of what necessarily follows from those axioms. She defends this view against objections that modal knowledge requires knowledge of abstract objects, and argues that we should understand possibility and necessity in a primative way.

The goal of this article is to suggest that in early modern discussions of agency and causal efficacy it is possible to detect an attempt at pushing to its extreme consequences a specific account of agency and causality that was developed in late scholastic thought. More specifically, the article examines Francisco Suárez's (1548–1617) account of freedom and how this relates to his views on efficient causality. Despite Suárez's careful way of differentiating between natural (necessary) and human (free) agents, his view (...) can be exploited to drive home occasionalist positions that deny causal efficacy for natural agents lacking reason. The family resemblance that might be noted between early modern positions could be traced back to the reception of a common late scholastic background and to the tensions and potential nestled there.

The frequency and severity of natural disasters and extreme weather events are increasing, taking a dramatic economic and relational toll on the communities they strike. Given the critical role that entrepreneurship plays in a community’s viability, it is necessary to understand how small business owners respond to these events and move forward over time. This study explores the long-term dynamics and trajectory of individuals within the broader business community following a natural disaster, paying particular attention to the influence of social (...) identity. Results suggest that the community identity changes over the course of recovery and rebuilding, underscoring the need for a holistic approach so that intervening agencies can achieve the sustainable economic recovery desired.

How can one knowingly choose against one's best judgment? This is both a traditional philosophical puzzle and a realistic problem in our everyday life. This dissertation is an exposition and examination of a recent work, by George Ainslie, with regard to its innovative explanation as well as rational solution of such a problem. With the help of the new Ainsliean model, I have also sought to offer some analysis of a number of issues that I believe are important to the (...) understanding of the nature of practical rationality. ;The central question for Ainslie's approach to the dynamic problem of preference change is how to justify the "bundling" idea underlying his solution of the problem by adopting a "personal rule." The bundling idea is a belief in the relation between a series of similar choices as each predicting the direction of all the later choices. Being able to think in terms of this bundling idea is a powerful means of abstaining from defection, though it requires considerable cognitive effort. I try to defend the plausibility of such a personal-rule approach. But Ainslie's own account falls short of showing the ultimate necessity of the bundling idea, viz., why the collapse of the whole sequence of choices would necessarily follow from one defection. My argument hinges on demonstrating that neither a causal consideration about the links between similar choices, nor a prudential consideration about the possible risk involved in certain actions is sufficient for understanding the necessity: we need a normative perspective instead. ;This leads to my analysis of the conditions under which a normative solution can be justified. The analysis also delineates the type of dynamic choice situations Ainslie's approach may adequately fit, or have the greatest advantage. Some underlying hypothesis about the status and role of cognition in desire and higher-level motivation is carefully discussed; and the cognitive, deliberative, and affective aspects of the adoption of a rule is explored. During my discussions, I also compare Ainslie's approach with other theories in the domain of practical reasoning, such as that of Donald Davidson's, Jon Elster's, Michael Bratman's, Edward McClennen's, and David Gauthier's, in terms of their explanatory power, or their scope of application, limits, and complementarity. ;Ainslie's motivational model of mind has apparent as well as potential implications for a group of interesting philosophical issues. They include the nature of willpower, the nature of practical rationality as well as moral rules, personal identity, autonomy, and the existentialist theme on self-creation. My conclusion is that the clarification of the metaphysical underpinnings of the Ainsliean model can help to shed some light on these issues. (shrink)

There is an ongoing debate in medicine about whether patients have a ‘right not to know’ pertinent medical information, such as diagnoses of life-altering diseases. While this debate has employed various ethical concepts, probably the most widely-used by both defenders and detractors of the right is autonomy. Whereas defenders of the right not to know typically employ a ‘liberty’ conception of autonomy, according to which to be autonomous involves doing what one wants to do, opponents of the right (...) not to know often employ a ‘duty’ understanding, viewing autonomy as involving an obligation to be self-governing. The central contribution of this paper is in showing that neither view of autonomy can reasonably be said to support the extreme stances on the right not to know that they are sometimes taken to. That is, neither can a liberty view properly defend a right not to know without limits, nor can a duty view form the basis of an absolute rejection of the right not to know. While there is still theoretical distance between these two approaches, we conclude that the views are considerably closer on this issue than they first appear, opening the way for a possible compromise.

In this thesis, I propose and defend a theory according to which committing oneself to knowing the proposition expressed counts as an assertion of that proposition. A consequence of this view is the knowledge account of assertion, according to which one asserts that p correctly only if one knows that p. In support of this approach, I offer a strategy of identifying an assertion’s “normative consequences”, types of act that normally take place as a result of one’s making an assertion (...) incorrectly. I outline two such phenomena: retraction and disavowal of knowledge. In continuation, I put the theory to test and critically examine four sets of objections against it, arguing that it can convincingly defuse them. Finally, I discuss two related issues: I maintain that by performing “aesthetic assertions” one also normally performs a non-assertoric speech act of recommendation, and argue for the possibility of “non-linguistic assertions”, whose content is expressed by gestures in appropriate contexts.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 33.1 (2000) 96-99 [Access article in PDF] Book Review The Long Path to Nearness: A Contribution to a Corporeal Philosophy of Communication and the Groundwork for an Ethics of Relief The Long Path to Nearness: A Contribution to a Corporeal Philosophy of Communication and the Groundwork for an Ethics of Relief. Ramsey Eric Ramsey. Atlantic Highlands, NJ: Humanities Press, 1998. Pp. xiv + 145. $49.95, cloth. (...) The cryptic title of Ramsey Eric Ramsey's new text creates a very useful metaphor that runs, as a long, sometimes winding, path through the wooded grounds of philosophy, communication, and ethics. The distance of the journey to corporeal communication and an ethics of relief is long in the sense that the journey requires most readers to shed some perceptual baggage as payment for passage. An example of such baggage shedding is Ramsey's effort to "re-call" communication. A valuable section of his work, it elicits an interesting new metaphorical perception of that which we take for granted.The premise that Ramsey works under is an acknowledged one of a critical existential Marxist who is influenced by Martin Heidegger. The additional [End Page 96] frame of this project is Calvin O. Schrag's 1987 book Communication Praxis and the Space of Subjectivity; indeed, Ramsey posits this work as a "building upon" Schrag's contribution. Certainly, in the use and understanding of communicative praxis, Ramsey does extend the work of Schrag. But there is more to Ramsey than new chapters in a story told earlier.Ramsey presents two arguments, along with well-sculpted, carefully detailed supporting premises that make the unfolding an enjoyable process. The issues of The Long Path to Nearness are (1) the neglected body in communication theory, which represents the inescapable contact point with the natural world, and (2) liberation ethics, explicated from an understanding of the absoluteness of uncertainty and the implications of responsibility. The arguments are fashioned around a Heideggerian "being-in-the-world" consciousness, one that, in its essence would presuppose both the body and the other as pretheoretical. Ramsey takes another approach, however, and avoids the transcendental while arguing, in a later context, for the transcendent.The long path begins with a phenomenological explication of the corporeal body, with a frequent and consistent implication of praxis as a sort of journey signpost (50 miles to Dallas... then 40 miles to Dallas, etc.) reminding the reader that practice is essential to the understanding of communication corporeality. In "re-calling" communication, Ramsey defines communication as a dynamic practice that offers possibility, possibility shaped by the binary of active and passive moments. For Ramsey's project, the passive moment is that which represents the material world and the inescapable Dasein that implies the body. Ramsey does not argue for an intercorporeality, choosing instead to imply the concept with a "being-in-the-world-with-other" perspective in the context of the corporeality argument. The active moment is the moment of subjectivity, which represents the consciousness of intentionality. Given Heidegger's definition of logos as "speaking" and Ramsey's professed phenomenological perspective (a study of being as opposed to knowing), possibility for Ramsey represents communication as "being-in-the-world-speaking" through a consciousness of intentionality and a material body presence. This presence in the world is practiced, negotiated, and experienced through communication.Ramsey's argument of possibility is an intricate exploration of the potentiality of horizons that are open-ended, endlessly challenging, and inviting potentiality for an ethics of liberation. Ramsey's explication of possibilities is one of the significant offerings of this effort, and is worth examination on the basis of its nuances and constructions.The overall argument for corporeality will be largely familiar to a European audience immersed in the body politic. This is not to say that the [End Page 97] effort does not offer new and inviting understandings, but rather to suggest that the premises of Ramsey's work best relate to those of continental thought regarding body presence. For those who... (shrink)
