The subject matter of the article is the concept of “the real use of reason” alluded to by Kant in Critique of Pure Reason A299/b355 and in A305/b362. After comparing it with the “real use of understanding” examined in De mundi sensibilis and in the Critique of Pure Reason, the real use of reason is presented as a legitimate and useful performance that should be distinguished from the deceiving illusion induced by an appearance (...) generated by reason itself. The real use of reason proves itself as an unavoidable condition for the regulative use of ideas as well as a condition for the production of a critical metaphysics. (shrink)

In this contribution, I respond to articles published in a Topical Issue of Open Philosophy on Kant’s Transcendental Dialectic by Mario Caimi, Gabriele Gava, and Michael Lewin, who criticize some of the views I put forward in my book Kant on the Sources of Metaphysics: The Dialectic of Pure Reason. In particular, I discuss the “real use” of reason, the “regulative use” of principles and ideas of reason, and Kant’s conception of reason.

This article demonstrates the ‘patterning’ of the ways discourse markers such as okay, right and yeah are used in academic lectures by native speaker lecturers. It presents an analysis of a) what the lecturers thought they would say and b) what they actually say in comparison to what the lecturers actually do say. In other words, it focuses on the differences between expectations of what would be said and speech, that is, what is actually said.The data comprise verbatim lecture transcriptions (...) of four native speaker lecturers of different disciplines, analysed using a discourse analytical approach. The findings and discussions exhibit the reasons for the differences between the ‘anticipated’ and ‘real’ meanings of the use of these discourse markers.They also reflect upon the significance of non-verbal features in determining the actual functions of these markers. In short, this article highlights the reality use of okay, right and yeah as interactive conversational markers in academic lectures. (shrink)

According to the traditional account Mendel's paper on pea hybrids reported a study of inheritance and its laws. Hence, Mendel came to be known as The Father of Genetics. This paper demonstrates that, in fact, Mendel's objective in his research was finding the empirical laws which describe the formation of hybrids and the development of their offspring over several generations. Having found these laws (and not the laws of inheritance that he is generally credited with) he proposed a theoretical scheme (...) involving the formation of germinal and pollen cells in hybrids and their combination in fertilization competent to explain why his laws took the form that they did. Mendel's research shows a pattern of development closely paralleling the stages of empirical investigation beginning at the level of qualitative description in common language rising through four levels of increasing abstraction and culminating in a fifth level, his simple mechanical theory. This mechanism met all the tests that a theory of this type must pass. In that respect Mendel was highly successful and this success might be the reason why he did not push his theory to a higher level, a sixth level involving the use of particulate determiners; despite this fact, Mendel was credited with having taken exactly that step.

Translating ethical theories into clinical practice presents a perennial challenge to educators. While many suggestions have been put forth to bridge the theory-practice gap, none have sufficiently remedied the problem. We believe the ascendance of hospital medicine, as a dominant new force in medical education and patient care, presents a unique opportunity that could redefine the way clinical ethics is taught. The field of hospital medicine in the United States is comprised of more than 50,000 hospitalists—specialists in inpatient medicine—representing the (...) fastest growing subspecialty in the history of medicine, and its members have emerged as a dominant new force around which medical education and patient care pivot. This evolution in medical education presents a unique opportunity for the clinical ethics community. Through their proximity to patients and trainees, hospitalists have the potential to teach medical ethics in real time on the wards, but most hospitalists have not received formal training in clinical ethics. We believe it is time to strengthen the ties between hospital medicine and medical ethics, and in this article we outline how clinical ethicists might collaborate with hospitalists to identify routine issues that do not rise to the level of an “ethics consult,” but nonetheless require an intellectual grounding in normative reasoning. We use a clinical vignette to explore how this approach might enhance and broaden the scope of medical education that occurs in the inpatient setting: A patient with an intra-abdominal abscess is admitted to the academic hospitalist teaching service for drainage of the fluid, hemodynamic support, and antimicrobial therapy. During the initial encounter with the hospitalist and his team of medical students and residents, the patient reports night sweats and asks if this symptom could be due to the abscess. How should the hospitalist approach this question? (shrink)

I argue that judgments of what is ‘true in a fiction’ presuppose the Reality Assumption: the assumption that everything that is true is fictionally the case, unless excluded by the work. By contrast with the more familiar Reality Principle, the Reality Assumption is not a rule for inferring implied content from what is explicit. Instead, it provides an array of real-world truths that can be used in such inferences. I claim that the Reality Assumption is essential to our ability (...) to understand stories, drawing on a range of empirical evidence that demonstrates our reliance on it in narrative comprehension. However, the Reality Assumption has several unintuitive consequences, not least that what is fictionally the case includes countless facts that neither authors nor readers could ever consider. I argue that such consequences provide no reason to reject the Reality Assumption. I conclude that we should take fictions, like non-fictions, to be about the real world. (shrink)

Jonathan Singer's witty, erudite book is a celebration of rationality and an urgent call to make use of intelligence and reason to better cope with human problems. Emphasizing the importance of rationality's greatest achievement, modern science, Singer—one of the foremost biologists of our era—argues that for the first time in several million years humanity has at its disposal the tools for an objective understanding of the external world. Singer demonstrates that, today more than ever, the fullest exercise of rationality (...) is essential if humanity is to rein in a runaway technology and control an explosion of the human population that together threaten to devastate life on this planet within only a few more generations. The intrusion of reason and rationality into our largely irrational world has been painfully slow, uneven, and often unwelcome. Singer explains that for rationalists the founding of modern science—which took place only a few hundred years ago—has overthrown many of the myths of conventional wisdom and dogmas of traditional religions. Yet these beliefs still hold sway over the irrational world, obstructing efforts to deal sensibly with the problematic future of mankind. The core of _The Splendid Feast of Reason _is an engaging and accessible account of the knowledge that modern science provides. Singer offers an absorbing discussion of how life works, of the nature of reproduction, aging, and death, and of the necessary fragility of the individual life compared to the resilience of life itself. He emphasizes the primary role of the genes in determining the structural organization and the behaviors of living things, including humans. He also stresses the nature and mechanisms of biological evolution, mechanisms that have now been placed in jeopardy because of human ignorance and irrational appetites. Finally, Singer delves into the enigma of the real world with its irrational and chaotic operations and offers suggestions of how a rationalist can not only survive, but thrive in it. (shrink)

The First World War was supposed to end all wars, though soon followed WWII. Since 1945 wars continued to abound; now we confront a real prospect of a third world war. Many armed struggles and wars arise in attempts to end repressive government; still more are fomented by repressive governments, few of which acknowledge their repressive character. It is historically and culturally naive to suppose that peace is normal, and war an aberration; war, preparations for war and threats of (...) war belong to ‘normal’ human life. Our tolerance, acceptance or fostering of such repeated injustices and atrocities indicate pervasive failures to understand fundamentals of justice, and what we owe morally to ourselves and to all others, together with our responsibilities to preserve the biosphere, not merely our own store(s) of reserves. As matters both of justice and prudence we must re-orient ourselves, individually and collectively, to promote justice, peace and ecological responsibilities by identifying and instituting just forms of social cooperation, domestically and internationally. All of these are our problems, whether we recognize them or continue our pervasive negligence. We urgently require cogent understanding of the social dimensions of human judgment, rational assessment, right action, and public reason. This requires understanding (inter alia) how Kant’s explication of rational judgment and justification is fundamentally social, how these features of rational judgment and justification are constitutive of Kant’s account of individual autonomy, and how they are central to Kant’s account of proper public use of reason. Reasoning publically remains precarious, not because – as often alleged – the ‘Enlightenment project’ has failed. It has not failed, it has been thwarted, and in our public responsibilities we have too often failed it. (shrink)

Kant (Grounding for the Metaphysics of Morals. Hackett, Indianapolis, 1797) described honesty as ‘a sacred command of reason’ which should be obeyed at all times and at any cost. This study inquires into the practice of dishonesty, deception, and deceit by universities in the UK in the pursuit of quality indicators such as league table positions, Research Excellence Framework (REF) scores, and student satisfaction survey results. Deception occurs when the metrics which inform these tables and surveys are manipulated to (...) suggest an improvement in quality when, in fact, the raised scores are merely the result of clever strategic planning. Deceit occurs when these manipulated scores are deliberately and knowingly presented as real improvements in research and educational quality. It might be argued that, within the context of the artificial ivory tower world of academe, this is a game played by almost every academic in every higher education institution with no real losers and little wider consequence. However, this study suggests that some of the strategies employed by institutions to improve their scores without directly addressing the issue of quality can, in certain practice‐based disciplines such as nursing, result in dire consequences for practitioners and service users. It concludes with a number of suggestions taken from personal experience to resolve the tension between the contractual demands placed on nurse academics by their employers and the moral and practical obligations of their professional body, most notably the use of subversion. The conclusion, contra Kant, is that the most effective strategy against dishonesty and deception is often more dishonesty and deception. (shrink)

Reason, we are told, is what makes us human, the source of our knowledge and wisdom. If reason is so useful, why didn't it also evolve in other animals? If reason is that reliable, why do we produce so much thoroughly reasoned nonsense? In their groundbreaking account of the evolution and workings of reason, Hugo Mercier and Dan Sperber set out to solve this double enigma. Reason, they argue with a compelling mix of real-life (...) and experimental evidence, is not geared to solitary use, to arriving at better beliefs and decisions on our own. What reason does, rather, is help us justify our beliefs and actions to others, convince them through argumentation, and evaluate the justifications and arguments that others address to us. In other words, reason helps humans better exploit their uniquely rich social environment. This interactionist interpretation explains why reason may have evolved and how it fits with other cognitive mechanisms. It makes sense of strengths and weaknesses that have long puzzled philosophers and psychologists--why reason is biased in favor of what we already believe, why it may lead to terrible ideas and yet is indispensable to spreading good ones.--.

The present paper looks at one of the most thorough articles on the intelligence of GPT, research conducted by engineers at Microsoft. Although there is a great deal of value in their work, I will argue that, for familiar philosophical reasons, their methodology, ‘Black-box Interpretability’ is wrongheaded. But there is a better way. There is an exciting and emerging discipline of ‘Inner Interpretability’ (also sometimes called ‘White-box Interpretability’) that aims to uncover the internal activations and weights of models in order (...) to understand what they represent and the algorithms they implement. In my view, a crucial mistake in Black-box Interpretability is the failure to appreciate that how processes are carried out matters when it comes to intelligence and understanding. I can’t pretend to have a full story that provides both necessary and sufficient conditions for being intelligent, but I do think that Inner Interpretability dovetails nicely with plausible philosophical views of what intelligence requires. So the conclusion is modest, but the important point in my view is seeing how to get the research on the right track. Towards the end of the paper, I will show how some of the philosophical concepts can be used to further refine how Inner Interpretability is approached, so the paper helps draw out a profitable, future two-way exchange between Philosophers and Computer Scientists.

Decision-making capacity in children and adolescents in healthcare requires thorough assessment: the minor's maturity, understanding of the decision, risk of the situation and contextual factors needs to be explored. The intention was to design and validate a test—the Maturtest—to assess the maturity of minors in decision-making processes in healthcare. A reasoning test on moral conflicts for adolescents was designed to infer the degree of maturity of minors applied to decision-making regarding their own health. The test was completed by a sample (...) of 441 adolescents aged from twelve to sixteen, with a corresponding analysis of their psychometric skills to measure feasibility, viability, reliability, validity, and sensitivity to change. Psychometric test results showed viability, reliability, validity, and sensitivity to change. High correlation between the test score and the reference method were notable. A high stability was obtained with an intraclass correlation coefficient. The average response time of the test was twenty-three minutes. This test measures the moral maturity of adolescents. It is presented as an objective, useful, valid, reliable tool, easy to fill out, edit and apply in a healthcare context. It helps to assess the maturity of minors faced with a decision. (shrink)

In this article, we provide a detailed discussion of Hasok Chang’s analysis of the Chemical Revolution. Our focus lies on his use of the framework of systems of practice and his claim that the abandonment of the phlogiston theory was irrational. We argue that his framework runs into problems when applied to the chemical revolution because of its static view on the aims of the historical actors and we suggest using Nicholas Jardine’s concept of the reality of questions instead as (...) a more flexible historiographical tool. We show how Chang’s claim regarding the irrational aspects of the chemical revolution follows from his strictly individualistic epistemology, leading him to see institutional and social aspects that impact the determination of aims as external to scientific rationality. We argue that a viable pragmatist and pluralist philosophy of science needs to embrace ‘academic politics’ as an explicit part of its view of rationality. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 33.2 (2000) 101-115 [Access article in PDF] Case Study of the Use of a Circumstantial Ad Hominem in Political Argumentation Douglas Walton In the 1860s, Northern newspapers attacked Lincoln's policies by attacking his character, using the terms drunk, baboon, too slow, foolish, and dishonest. Steadily on the increase in political argumentation since then, the argumentum ad hominem has been carefully refined as an instrument of "oppo (...) tactics" and "going negative" by the public relations experts who now craft political campaigns at the national level. It has been so prominently used in the major political campaigns, debates, and advertisements of the past few years that there has even been a reaction against it--a feeling that we have gone too far in this direction and that some kind of restraint is needed. 1 But there has been no evidence of such restraint in the argumentation used in recent campaigns. Perhaps what might be helpful is a better understanding on the part of voters and campaigners of how to evaluate ad hominem arguments critically.How does the ad hominem argument really work as a way of molding public opinion, why is it so often so effective, and how can it be defended against? How can it be evaluated as a clearly identifiable type of argument, by some kind of objective standards, in a way that can be applied to particular cases? These appear to be tough questions, but recent research has made some not inconsiderable progress toward answering them.The purpose of this article is to present a new case study of a type of argument commonly used in political discourse, a case study that makes use of the dialectical normative framework for identifying and evaluating personal attack (ad hominem) arguments that is developed in a series of works by Henry W. Johnstone Jr. (1952); Alan Brinton (1985, 1995); Frans H. van Eemeren and Rob Grootendorst (1984, 1995); Erik C. W. Krabbe and Douglas N. Walton (1993), Walton (1989, chap. 6; 1998); and van Eemeren, Grootendorst, Francisca Snoeck Henkemans et al. (1996). This particular case, although typical of so many ad hominem arguments currently [End Page 101] in use in political discourse, has some special features that turn out to be quite interesting not only in showing how the dialectical framework applies to cases, but also in advancing our knowledge of how the ad hominem type of argument works in political argumentation in a democratic system for which the media reportage of events is a big factor in influencing voting. 1. Framework for analysis and evaluation Although the argumentum ad hominem, or personal attack argument, has been traditionally treated as a fallacy in logic, recent research in argumentation (as cited above) shows that, in many cases,--including cases in political argumentation--ad hominem arguments, as used in conversational arguments, are not fallacious. Research has shown that, while some personal attack arguments can definitely be judged fallacious, many others are quite reasonable (when evaluated in the appropriate context), while still others should be evaluated as weak (insufficiently supported) but not fallacious. As shown in this case study, the real function of an ad hominem argument (when properly used) is to attack an arguer's credibility in order to criticize the argument she advocates.Before going any further, it is necessary to define some terminology brought to use in the research cited above. An ad hominem argument is the use of personal attack in a dialogue exchange between two parties, where the one party attacks the character of the other party as bad, in some respect, and then uses this attack as a basis for criticizing the other party's argument. An argument is fallacious if it is a special baptizable (Johnson 1987) type of argument that is used by one party in a dialogue exchange in such a way that it blocks or interferes with the collaborative realization of the goal of the type of dialogue in which the two participants are supposed to be engaged (Walton 1995). Thus, there is a difference between a weak... (shrink)

Introduction There is a paramount need for moral development for pharmacists and pharmacy students to practice the patient-centered profession. We aimed to explore the current situational judgment utilizing ethical reasoning among undergraduate pharmacy students. Methods A set of ten ethical dilemmas, representing potential real-life situations that the students come across in the university and may face in the future as a pharmacist were developed by a team of students, academic staff, and stakeholders. These ethical dilemmas were validated, checked for (...) accuracy, and piloted. An online questionnaire was created consisting of these ten scenarios as open-ended questions and administered to fourth year and fifth year PharmD students in a public university located at the city of Mecca, Saudi Arabia, asking them how they would react in that situation. Responses of the participants were analyzed using thematic analysis independently by four researchers and inter-rater agreement were achieved through consensus. Results Out of 205, 186 students completed the questionnaire with a response rate of 90.7%. Analysis and resulted in the generation of 32 codes, which were then categorized into seven overarching themes: student engagement, social and professional responsibility, academic integrity, legal obligation, moral obligation, signposting, and moral engagement and patient safety. Conclusions Undergraduate pharmacy students experience complex state of mind in connection with ethical reasoning. The participants’ situational judgment were driven by cultural norm, authority, and responsibility. Student engagement is also affected by the state of mind and feelings of mutual trust, perceived cultural influence and peer pressure. The students were prone to seek help from university administrators or teachers when faced with situations in which they were helpless. (shrink)

To what use can causal claims established in good studies be put? We give examples of studies from which inaccurate inferences were made about target policy situations. The usual diagnosis is that the studies in question lack external validity, which means that the same results do not hold in the target as in study. That’s a label that just repeats what we already knew. We offer a deeper analysis. Our analysis points to the need for interdisciplinarity and to the demand (...) to focus not on the study – as the expression ‘external validity’ invites you to do – but on the target. The call for interdisciplinary approaches to real life problems is common since it is widely acknowledged that what happens in the real world seldom falls under the auspices of any single research domain. Our focus is on one specific real life problem: how to use causal claims from good studies to help predict whether the policies tested will work in a new situation. Our analysis of what it takes to back up these predictions points up very specific stages in the process of prediction where we are bound to get it wrong if we do not diversify our concepts, our knowledge and our methods. We isolate two reasons inferences from study to target fail. First, policy variables do not produce results on their own; they need helping factors. The distribution of helping factors is likely to be unique or local for each study, so one cannot expect external validity to be all that common. Second, researchers often give too concrete a description of the cause in the study for it to carry over to the target.ion is necessary to get causes that travel. There is no sure-fire way to guard against these problems. But the unavailability of one perfect tool does not imply there are no second best contrivances. Two general pointers for Good Practice in policy advice follow from our diagnosis: focus on the concrete details in the target and use cross discipline heuristics that diversify background knowledge.

BackgroundUse of modified texture diets—thickening of liquids and modifying the texture of foods—in the hope of preventing aspiration, pneumonia and choking, has become central to the current management of dysphagia. The effectiveness of this intervention has been questioned. We examine requirements for a valid informed consent process for this approach and whether the need for informed consent for this treatment is always understood or applied by practitioners.Main textValid informed consent requires provision of accurate and balanced information, and that agreement is (...) given freely by someone who knows they have a choice. Current evidence, including surveys of practitioners and patients in different settings, suggests that practice in this area is often inadequate. This may be due to patients’ communication difficulties but also poor communication—and no real attempt to obtain consent—by practitioners before people are ‘put on’ modified texture diets. Even where discussion occurs, recommendations may be influenced by professional misconceptions about the efficacy of this treatment, which in turn may poison the well for the informed consent process. Patients cannot make appropriate decisions for themselves if the information provided is flawed and unbalanced. The voluntariness of patients’ decisions is also questionable if they are told ‘you must’, when ‘you might consider’ is more appropriate. Where the decision-making capacity of patients is in question, inappropriate judgements and recommendations may be made by substitute decision makers and courts unless based on accurate information.ConclusionResearch is required to examine the informed consent processes in different settings, but there is ample reason to suggest that current practice in this area is suboptimal. Staff need to reflect on their current practice regarding use of modified texture diets with an awareness of the current evidence and through the ‘lens’ of informed consent. Education is required for staff to clarify the importance of, and requirements for, valid informed consent and for decision making that reflects people’s preferences and values. (shrink)

In this study, Knauff and Johnson-Laird's visual impedance hypothesis is applied to the domain of external representations and diagrammatic reasoning. We show that the use of real objects and augmented real objects can control human interpretation and reasoning about conditionals. As participants made inferences, they also moved objects corresponding to premises. Participants who moved real objects made more invalid inferences than those who moved AR objects and those who did not manipulate objects. Our results showed that (...) class='Hi'>real objects impeded conditional reasoning, but AR objects did not. These findings are explained by the fact that real objects may over-specify a single state that exists, while AR objects suggest multiple possibilities. (shrink)

Going back to Jacobi, commentators have often considered Kant’s notion of the transcendental object (thing in itself, monad, or object = X) to be concerned merely with empirical affection. Although most agree that this argument of Kant’s forbids the understanding from making illegitimate claims regarding the transcendental object, it is often assumed that no positive function can be ascribed to metaphysical illusions produced by reason. I will show in this paper, in contrast to most commentators, that a positive notion (...) of transcendental illusion is brought about by the cooperation of the imagination and reason in the latter’s pursuit of positing transcendental objects––in the same way that the imagination aids the understanding in determining objects of empirical cognition. When describing reason’s pursuit of systematicity, Kant writes that the transcendent ideas serve as a focus imaginarius that unifies cognition as such (A644/B672). It is not merely the case that metaphysical illusions regarding the soul, the world as such, and God are entirely useless, just because the understanding is prohibited from claiming having knowledge of such concepts.I take it that the transcendental object so considered in Kant’s Dialectic refers only to a representation of the imagination. I show that all three transcendental ideas––namely, God, the World as such, and the soul––are imaginary projections of unity carried out by the power of reason. Drawing on Kant’s notion of the focus imaginarius, I claim that reason regards transcendental illusions as being real objects. This holds as much for the schema of scientific knowledge, which is merely regulative, as it does for the three transcendental ideas. Unlike most commentators, I do not take Kant’s consideration of the transcendental object to concern empirical affection. Rather, reason posits this object in order to transcend the limits of the understanding, and to thereby use its own inner illusions for systematic purposes (cf. A250–53 and A393). To my mind, reason necessarily posits ideas, but the imagination often leads reason into holding that the focus imaginarius of the idea is an actual object. The critical use of reason must then put limits on the imagination (cf. A770/B798). But the imagination nonetheless serves reason’s interest by allowing it to put otherwise negative illusions to work for the sake of systematicity. (shrink)

Background: Priority setting is necessary in current healthcare services. Discussion of fair process has highlighted the value of developing reasons for allocation decisions on the basis of experience gained from real cases.Aim: To identify the reasons that those with experience of real decision-making concerning resource allocation think relevant in deciding on the priority of a new but expensive drug treatment.Methods: Semistructured interviews with members of committees with responsibility for making resource allocation decisions at a local level in the (...) British National Health Service, analysed using modified grounded theory.Results: 22 interviews were carried out. 14 reasons were identified. Four reasons were almost universally considered most important: cost effectiveness; clinical effectiveness; equality and gross cost. No one reason was considered dominant. Some considerations, such as political directives and fear of litigation, were thought by many participants to distort decision-making. There was a substantial lack of agreement over the relevance of some reasons, such as the absence of alternative treatment for the condition.Conclusions: There is a clear consensus on the importance and role of a limited number of reasons in allocation decisions among participants. A focus on the process of decision-making, however, does not obviate the need for those involved in the process to engage with problematical ethical issues, nor for the importance of further ethical analysis.

An introductory logic textbook. The Art of Reasoning, 5e, shows students how logic can be applied to everyday life in each chapter, uses real-world examples to explain core concepts, and includes a new chapter on the cognitive biases and errors students are most likely to encounter in their own thinking.

Artificial intelligence (AI) has attracted an increasing amount of attention, both positive and negative. Its potential applications in healthcare are indeed manifold and revolutionary, and within the realm of medical imaging and radiology (which will be the focus of this paper), significant increases in accuracy and speed, as well as significant savings in cost, stand to be gained through the adoption of this technology. Because of its novelty, a norm of keeping humans “in the loop” wherever AI mechanisms are deployed (...) has become synonymous with good ethical practice in some circles. It has been argued that keeping humans “in the loop” is important for reasons of safety, accountability, and the maintenance of institutional trust. However, as the application of machine learning for the detection of lumbar spinal stenosis (LSS) in this paper’s case study reveals, there are some scenarios where an insistence on keeping humans in the loop (or in other words, the resistance to automation) seems unwarranted and could possibly lead us to miss out on very real and important opportunities in healthcare—particularly in low-resource settings. It is important to acknowledge these opportunity costs of resisting automation in such contexts, where better options may be unavailable. Using an AI model based on convolutional neural networks developed by a team of researchers at NUH/NUS medical school in Singapore for automated detection and classification of the lumbar spinal canal, lateral recess, and neural foraminal narrowing in an MRI scan of the spine to diagnose LSS, we will aim to demonstrate that where certain criteria hold (e.g., the AI is as accurate or better than human experts, risks are low in the event of an error, the gain in wellbeing is significant, and the task being automated is not essentially or importantly human), it is both morally permissible and even desirable to kick the humans out of the loop.

This paper investigates the following question: when can one reliably infer the existence of an intersection point from a diagram presenting crossing curves or lines? Two cases are considered, one from Euclid's geometry and the other from basic real analysis. I argue for the acceptability of such an inference in the geometric case but against in the analytic case. Though this question is somewhat specific, the investigation is intended to contribute to the more general question of the extent and (...) limits of reliable diagrammatic reasoning in mathematics.

And the aesthetic-political rationality in Foucault’s ethics is compared with Wellner’s suggestions of holding on to the notion of code but with a new (...) meaning.

The current paper details a restricted semantics for active logic, a time-sensitive, contradictiontolerant logical reasoning formalism. Central to active logic are special rules controlling the inheritance of beliefs in general, and beliefs about the current time in particular, very tight controls on what can be derived from direct contradictions (P &¬P ), and mechanisms allowing an agent to represent and reason about its own beliefs and past reasoning. Using these ideas, we introduce a new definition of model and of (...) logical consequence, as well as a new definition of soundness such that, when reasoning with consistent premises, all classically sound rules are sound for active logic. However, not everything that is classically sound remains sound in our sense, for by classical definitions, all rules with contradictory premises are vacuously sound, whereas in active logic not everything follows from a contradiction.

Diagnostic errors are more frequently a result of the clinician's failure to combine medical knowledge adequately than of data inaccuracy. Diagnostic reasoning studies are valuable to understand and improve diagnostic reasoning. However, most diagnostic reasoning studies are characterized by some limitations which make these studies seem more simple than diagnostic reasoning in real life situations actually is. These limitations are connected both to the failure to acknowledge components of knowledge used in clinical practice as well as to acknowledge the (...) physician-patient relationship's influence on clinical knowledge and on the reasoning process itself. In addition the modes of reasoning described in these studies frequently is oversimplified. In this paper three simplistic and competing models of diagnostic reasoning are analyzed and criticized, followed by an evaluation of two alternative models proposing a combined view. (shrink)

Interpretation is the process whereby a hearer reasons to an interpretation of a speaker's discourse. The hearer normally adopts a credulous attitude to the discourse, at least for the purposes of interpreting it. That is to say the hearer tries to accommodate the truth of all the speaker's utterances in deriving an intended model. We present a nonmonotonic logical model of this process which defines unique minimal preferred models and efficiently simulates a kind of closed-world reasoning of particular interest for (...) human cognition. Byrne's “suppression” data (Byrne, 1989) are used to illustrate how variants on this logic can capture and motivate subtly different interpretative stances which different subjects adopt, thus indicating where more fine-grained empirical data are required to understand what subjects are doing in this task. We then show that this logical competence model can be implemented in spreading activation network models. A one pass process interprets the textual input by constructing a network which then computes minimal preferred models for (3-valued) valuations of the set of propositions of the text. The neural implementation distinguishes easy forward reasoning from more complex backward reasoning in a way that may be useful in explaining directionality in human reasoning. (shrink)

This research ethics article focuses on an unexpected finding from my Master’s thesis examining bereaved participants’ experiences of taking part in sensitive qualitative research: some participants wanted their real names used in my written dissertation and any subsequent empirical publications. While conducting interviews for my thesis and explaining the consent process, early responses highlighted the problematic notion of anonymity for participants engaged in qualitative research. Several participants asserted the significance of immortalizing their deceased loved ones in the pages of (...) my thesis, retaining ownership over their words and maintaining a public attachment to their personal identity. The preliminary responses also resonate with concerns regarding the ethics of assigning pseudonyms and anonymity to participants in qualitative research. Themes in the extant literature tend to centre on issues of researchers’ accountability and transparency towards participants or respect. The present article contributes to the debates surrounding anonymity and confidentiality within qualitative research, and also expands on specific issues pertaining to bereavement research ethics.

Concern about high-profile ethical lapses by business managers has led to an increasing emphasis on ethics instruction in business schools. Various pedagogical methods are used to expose business students to real-world ethical dilemmas, yet students may not readily grasp the linkages between ethical theories and dilemmas to identify possible ethical solutions. Venn diagrams are a valuable instructional tool in business ethics classes when used with other teaching methodologies such as case studies. We describe how the use of Venn diagrams (...) assists students in visualizing the key points of and the connections between ethical theories and dilemmas to shed light on possible ethical solutions. Examples of teaching exercises are provided along with ideas for future research in the use of Venn diagrams in activating moral imagination and improving ethical reasoning. Overall, positive student reactions to the introduction of Venn diagrams in business ethics classrooms support the use of this methodology. (shrink)

Many formalisms for reasoning about knowing commit an agent to be logically omniscient. Logical omniscience is an unrealistic principle for us to use to build a real-world agent, since it commits the agent to knowing infinitely many things. A number of formalizations of knowledge have been developed that do not ascribe logical omniscience to agents. With few exceptions, these approaches are modifications of the possible-worlds semantics. In this paper we use a combination of several general techniques for building non-omniscient (...) reasoners. First we provide for the explicit representation of notions such as problems, solutions, and problem solving activities, notions which are usually left implicit in the discussions of autonomous agents. A second technique is to take explicitly into account the notion of resource when we formalize reasoning principles. We use the notion of resource to describe interesting principles of reasoning that are used for ascribing knowledge to agents. For us, resources are abstract objects. We make extensive use of ordering and inaccessibility relations on resources, but we do not find it necessary to define a metric. Using principles about resources without using a metric is one of the strengths of our approach.We describe the architecture of a reasoner, built from a finite number of components, who solves a puzzle, involving reasoning about knowing, by explicitly using the notion of resource. Our approach allows the use of axioms about belief ordinarily used in problem solving – such as axiom K of modal logic – without being forced to attribute logical omniscience to any agent. In particular we address the issue of how we can use resource-unbounded (e.g., logically omniscient) reasoning to attribute knowledge to others without introducing contradictions. We do this by showing how omniscient reasoning can be introduced as a conservative extension over resource-bounded reasoning. (shrink)

Here I defend my solution to the wrong-kind-of-reason problem against Mark Schroeder’s criticisms. In doing so, I highlight an important difference between other accounts of reasons and my own. While others understand reasons as considerations that count in favor of attitudes, I understand reasons as considerations that bear (or are taken to bear) on questions. Thus, to relate reasons to attitudes, on my account, we must consider the relation between attitudes and questions. By considering that relation, we not only (...) solve the wrong-kind-of-reason problem, but we also bring into view rational agency—the use of reasons in thought. (shrink)

Reasoning is a goal-oriented activity. The logical steps are at best the median part of a full reasoning: before them, a language has to be defined, and a model of the goal in this language has to be developed; after them, their result has to be checked in the real world with respect to the goal. Both the prior and the subsequent steps can be conducted rationally; none of them has a logical counterpart. Furthermore, Logic aims at prescribing what (...) a correct reasoning is. But correct with respect to what? If the answer is: with respect to truth, the next question is whether the truth in everyday life, physics, economy, is the same as the truth that logicians have in mind. Resorting to Logic is justified only if an idealization in terms of true propositions in the logical sense is compatible with the goal. If such an idealization is legitimate, so is the use of classical Logic. If not, there is no authority forbidding to skew Logic in order to better reflect the nature of the reasoning required for the task. (shrink)

This article attempts to read the Transcendental Dialectic through Meillassoux’s model of the absolute contingency of being in order to rethink some of its central difficulties. Specifically, this concerns better understanding the role played by the categories of relation and modality in the empirical use of the ideas of reason, which underlies their regulative use that is directed at an absolute unity of reason. It will be discussed which questions are implied in the central claim of Meillassoux’s ontology, (...) i.e., that it is possible to derive from the necessity of contingency the existence and noncontradictory being of the thing in itself. First, I will retrace basic points of Meillassoux’s critique of “correlationism”, by means of which he reconfigures the divisions between metaphysics, physics, and ontology. Second, against the background of the Kantian concept of hope, I will examine a relation between the Transcendental Dialectic and ethics, as, respectively, conceived of in Kant and in Meillassoux’s reinterpretation. Third, I will critically ask in how far absolute contingency can be understood as grounding a concept of experience and in which sense the idea of the antinomy chapter in the Transcendental Dialectic contains an argument more complex than Meillassoux’s model suggests.

In this paper I begin by examining Fogelin’s account of deep disagreement. My contention is that this account is so deeply flawed as to cast doubt on the possibility that such deep disagreements actually happen. Nevertheless, I contend that the notion of deep disagreement itself is a useful theoretical foil for thinking about argumentation. The second part of this paper makes this case by showing how thinking about deep disagreements from the perspective of rhetoric, Walton-style argumentation theory, computation, and normative (...) pragmatics can all yield insights that are useful no matter what one’s orientation within the study of argument. Thus, I conclude that deep disagreement –even if it were to turn out that there are no real-world occurrences of it to which we can point–is useful for theorists of argumentation. In this wise, deep disagreement poses a theoretical challenge for argumentation theory not unlike that posed by radical skepticism for traditional epistemology. (shrink)

One of the most unsettling problems in the history of philosophy examines how mathematics can be used to adequately represent the world. An influential thesis, stated by Eugene Wigner in his paper entitled "The Unreasonable Effectiveness of Mathematics in the Natural Sciences," claims that "the miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve." Contrary to this view, this thesis delineates and implements (...) a strategy to show that the applicability of mathematics is very reasonable indeed. I distinguish three forms of the problem of the applicability of mathematics, and focus on one I call the problem of uncanny accuracy: Given that the construction and manipulation of mathematical representations is pervaded by uncertainty, error, approximation, and idealization, how can their apparently uncanny accuracy be explained? I argue that this question has found no satisfactory answer because our rational reconstruction of scientific practice has not involved tools rich enough to capture the logic of mathematical modelling. Thus, I characterize a general schema of mathematical analysis of real systems, focusing on the selection of modelling assumptions, on the construction of model equations, and on the extraction of information, in order to address contextually determinate questions on some behaviour of interest. A concept of selective accuracy is developed to explain the way in which qualitative and quantitative solutions should be utilized to understand systems. The qualitative methods rely on asymptotic methods and on sensitivity analysis, whereas the quantitative methods are best understood using backward error analysis. The basic underpinning of this perspective is readily understandable across scientific fields, and it thereby provides a view of mathematical tractability readily interpretable in the broader context of mathematical modelling. In addition, this perspective is used to discuss the nature of theories, the role of scaling, and the epistemological and semantic aspects of experimentation. In conclusion, we argue for a method of local and global conceptual analysis that goes beyond the reach of the tools standardly used to capture the logic of science; on their basis, the applicability of mathematics finds itself demystified.

In his new book "The Importance of Being Rational", Errol Lord aims to give a real definition of the property of rationality in terms of normative reasons. If he can do so, his work is an important step towards a defense of ‘reasons fundamentalism’ – the thesis that all complex normative properties can be analyzed in terms of normative reasons. I focus on his analysis of epistemic rationality, which says that your doxastic attitudes are rational just in case they (...) are correct responses to the objective normative reasons you possess. For some fact to be an objective normative reason to do something that you possess, you have to be in a position to know this fact and be able to competently use it as a reason to do that thing. Lord’s view is thus a knowledge-first view about possessing normative reasons. Throughout the book, Lord conceptualizes belief in the traditional tripartite way – if you take any attitude at all towards a proposition, then you either believe it, or disbelieve it, or you suspend judgment about it. Lord doesn’t discuss cases in which we’re uncertain. Yet, those cases are ubiquitous. I explore how his view can be extended to them. I first discuss whether his strategy for vindicating coherence requirements in terms of normative reasons can be applied to credences. I then ask how Lord can conceive of the doxastic attitudes that encode uncertainty . (shrink)

Interpretation is the process whereby a hearer reasons to an interpretation of a speaker's discourse. The hearer normally adopts a credulous attitude to the discourse, at least for the purposes of interpreting it. That is to say the hearer tries to accommodate the truth of all the speaker's utterances in deriving an intended model. We present a nonmonotonic logical model of this process which defines unique minimal preferred models and efficiently simulates a kind of closed‐world reasoning of particular interest for (...) human cognition. Byrne's “suppression” data (Byrne, 1989) are used to illustrate how variants on this logic can capture and motivate subtly different interpretative stances which different subjects adopt, thus indicating where more fine‐grained empirical data are required to understand what subjects are doing in this task. We then show that this logical competence model can be implemented in spreading activation network models. A one pass process interprets the textual input by constructing a network which then computes minimal preferred models for (3‐valued) valuations of the set of propositions of the text. The neural implementation distinguishes easy forward reasoning from more complex backward reasoning in a way that may be useful in explaining directionality in human reasoning. (shrink)

Withdrawal is an act by which a member state of an international organization willingly terminates its membership. The right to withdraw from international organizations is explicitly mentioned in the constitutions of most of them and the circumstances regarding to the right of withdrawal vary depending on the organization. The purpose of this paper is to explain the right and procedures of withdrawal, and the reasons that result with the will of states to withdraw from international organizations. For the realization of (...) this research are used qualitative methods, based on the bibliography that is related to international organizations, with special emphasis with the right and procedures of the withdrawal of states from international organizations. Furthermore, some informations are also collected from the credible internet sources, which have valuable data about the withdrawals of states from international organizations and the reasons that result with such decisions. The results of the research have shown that since the appearance of international organizations until today, there were and there are decisions of states to withdraw from international organizations, coming from the reluctance of states to hand over to international organizations parts of their sovereignty. The conclusions of this paper aim to increase knowledge about the real meaning of the processes of withdrawals of states from international organizations. (shrink)

On Kant’s account, “public use of reason” is the use that a truth-seeking scholar makes of his reason when he communicates his thoughts in writing to a world of readers. Commentators tend to treat this account as expressing an egalitarian ideal, without taking seriously the limiting conditions—especially the scholarship condition—built into it. In this paper, I interrogate Kant’s original account of public reason in connection with his construction of the “Oriental” as a linguistically and therefore epistemically and (...) culturally inferior Other. I thereby give reasons to worry that Kant’s account is substantively inegalitarian (even if it is nominally egalitarian). I also draw attention to the fact that Kant constructed a linguistic Other against the backdrop of colonialism and from a position of power. This positionality gave what he said about the Other an ideology-forming and world-making effect. In this way, his exclusionary discursive practices—such as depicting the Oriental as an inferior linguistic Other—could have a lasting impact on knowledge production and on the real-world exercise of public reason.

For Kant one of the goals of any critique of pure reason is to answer the question, how are a priori synthetic propositions possible? Because rationalists such as Eberhard and Wolff took the principle of sufficient reason (hereafter, the PSR) as the principle of all a priori synthetic judgments, understanding both the various formulations of this principle and arguments in favor of its use as an axiom in metaphysical reasoning provides an interesting back door to understanding The Critique (...) of Pure Reason. Despite his statements in the First Critique rejecting the PSR as a principle of judgment1, I argue that Kant was actually more sympathetic to the PSR than these passages alone would suggest. The Kant-Eberhard Controversy suggests that, even though Kant explicitly denies that the PSR can guide metaphysical reasoning, he actually presupposes its truth. I show that Kant’s position is tenable because, like the rationalists, Kant accepts the assumption that real essences exist and that they ground real possibility2; this leads him to accept the truth of all clear statements of the PSR. Unlike the rationalists, however, he does not accept the assumption that human understanding is isomorphic with real essences. As a result, Kant rejects only the use of the PSR to determine a priori the existence or properties of a thing. In this paper I hope to illuminate this position. I will begin with a survey of the various formulations of the PSR that have been put forward by Kant and his predecessors: Leibniz, Eberhard, and Wolff. Then I will examine Wolff and Eberhard’s arguments in favor of the PSR along with Kant’s criticisms of these arguments. Lastly, I will show why Kant rejected the very possibility of justifying this use of the PSR while presupposing its truth. (shrink)

In climate science, observational gridded climate datasets that are based on in situ measurements serve as evidence for scientific claims and they are used to both calibrate and evaluate models. However, datasets only represent selected aspects of the real world, so when they are used for a specific purpose they can be a source of uncertainty. Here, we present a framework for understanding this uncertainty of observational datasets which distinguishes three general sources of uncertainty: (1) uncertainty that arises during (...) the generation of the dataset; (2) uncertainty due to biased samples; and (3) uncertainty that arises due to the choice of abstract properties, such as resolution and metric. Based on this framework, we identify four different types of dataset ensembles — parametric, structural, resampling, and property ensembles—as tools to understand and assess uncertainties arising from the use of datasets for a specific purpose. We advocate for a more systematic generation of dataset ensembles by using these sorts of tools. Finally, we discuss the use of dataset ensembles in climate model evaluation. We argue that a more systematic understanding and assessment of dataset uncertainty is needed to allow for a more reliable uncertainty assessment in the context of model evaluation. The more systematic use of such a framework would be beneficial for both scientific reasoning and scientific policy advice based on climate datasets. (shrink)

Modelling human reasoning characterizes the fundamental human cognitive capacity to describe our past experience and use it to form expectations as well as plan and direct our future actions. Natural language semantics analyzes dynamic forms of reasoning in which the real-time order determines the temporal relations between the described events, when reported with telic simple past-tense clauses. It provides models of human reasoning that could supplement ACT-R models.

In lieu of an abstract, here is a brief excerpt of the content:Perceptions of Exile in Cicero: The Philosophical Interpretation of a Real ExperienceEmanuele Narducci1Dolor is a keyword in Ciceronian oratory: a direct and explicit token of deep emotional involvement, the term underlines the display, through the performance of the orator, of the psychological and moral suffering which lends credibility to the passion in his words, to his outbursts of indignation and to his appeals to pity. 1 Antonius insists (...) on this point when recalling the tones of dramatic pathos to which he had recourse in his defence of Aquilius: non fuit haec sine meis lacrumis, non sine dolore magno miseratio omniumque deorum et hominum et civium [...]. Si dolor afuisset meus, non modo miserabilis, sed etiam inridenda fuisset oratio mea (De oratore 2.196). Not unlike Antonius, Cicero himself explains his own surpassing skill in delivering moving perorationes: ut viderer excellere non ingenio sed dolore assequebar (Orator 130).From such statements it is quite clear that in the law courts the rhetorical manoeuvre is not unusual whereby the orator, in the most emotionally charged passages, displays to the judges the dolor which inspires his words. 2 In this show of emotions Cicero saw something both [End Page 55] akin to that staged by actors in the theatre and at the same time something very different. The difference, as Antonius once again stresses in De oratore 2.194, lies in the fact that the orator does not play another’s role, but enacts his own part (neque actor sum alienae personae, sed auctor meae). 3The definition of the orator as an auctor personae suae perhaps fits none of Cicero’s speeches better than De domo sua. In this address he speaks not as a patronus to defend another, but to claim his own property and the right to take his place once again and fully at the heights of Roman society after the humiliation of his exile. 4 We can therefore believe what, shortly after delivering the speech, he writes to Atticus about the genuineness of the feelings which dictated his words: secuta est summa contentio de domo. Diximus apud pontifices pridie K. Octobres. Acta res est accurate a nobis, et, si umquam in dicendo fuimus aliquid, aut etiam si numquam alias fuimus, tum profecto dolor reique magnitudo vim quandam nobis dicendi dedit (Ad Atticum 4.2.2).Throughout De domo sua, Cicero makes a show of still bearing in his heart the marks of that same suffering with which in 58 he had faced parting from Rome and his dear ones, and confronted his later wanderings before the long-awaited recall. But what he actually provides us with in this speech is a reinterpretation of his personal experience of exile ably aimed at restoring his auctoritas, his prestige and his overall political image. 5 For this reason the low spirits, dejection, and discouragement which had distinguished the period of his exile (and which are attested in much of his correspondence) undergo a profound transformation. In De domo sua and even earlier in the Post reditum speeches, the decision to abandon Rome without facing the struggle with Clodius is presented not as being determined by anguish and an awareness of his [End Page 56] own political isolation, but as the result of a rationally considered choice, and one based on the certainty that resorting to armed defence would have quickly thrown the city into a state of chaos. Cicero describes his departure in the terms of a sacrifice, of an out and out devotio on behalf of the res publica and all the boni. He drives home the utter untimeliness of a conflict which would have ranged Gabinius and Piso on the side of the improbi and probably given rise to a social upheaval, with the Roman state being handed over to the slaves. This argument, which plays upon an atavistic fear felt by the ruling classes, is often used by Cicero in his attacks on Clodius. 6As we shall see more clearly later, Cicero’s philosophical studies have had a considerable influence on the formation of this rhetoric of the struggle’s abandonment and on its general coloring. But what is the philosophy that can be glimpsed... (shrink)

The aim of this paper is to discuss a parallel in the thinking of STS scholar Sheila Jasanoff and philosopher Adam Elga. Although both subscribe to the norms of their respective discipline—Elga using a priori conceptual analysis and Jasanoff conducting empirical case studies—they both reason in similar ways regarding epistemic hierarchy in political controversy. They argue that controversial questions are enmeshed in such a way with political framework that there can be no purely epistemic evaluation of expertise. This conclusion (...) is unexpected for a parallel between STS and philosophy of science since it is not based on a normative theory of expertise. While there has been collaboration between the two fields in the wake of the so-called “third wave” movement in science studies, the parallel discussed in this paper opens up the potential for collaborative research based on a skeptical view of expertise and epistemic authority.
