In my thesis I explain why the common, pre-theoretical understanding of morality is an important part of Kant’s ethics, and I critically evaluate what the strengths and weaknesses are of doing ethics with the common perspective as a point of reference. In chapter 1, I discuss the significance of common rational capacities for the deduction in Groundwork III as well as for the Fact of Reason. Attention to the fundamental role of common rational capacities in (...) the Second Critique reveals that Kant intends to provide further warrant for the Fact than its introspective self-evidence. In chapter 2, I discuss what it means for a rational agent to be endowed with common rational capacities. The agent has everything she needs to reason on her own about what she ought to do and act from rational judgements. Furthermore, I critically evaluate Kant’s claim that his ethics spells out fundamental, pre-theoretical convictions. In chapter 3, I discuss Kant’s conception of rationalizing. I analyse rationalizing as a process of self-deception in which an agent tries to justify or excuse violations of the moral law. This can lead to loss of the reliable use of common rational capacities. I discuss what help critical practical philosophy and moral education can afford against rationalizing. In chapter 4, I argue that Kant saw dialogical engagement with ordinary agents as an important way of obtaining data concerning the correct starting point of practical philosophy. Kant demands that whatever we get from dialog and observation has to be isolated from its contingent elements. I conclude that the main problem for Kant’s method is how we can, on the one hand, exclude non-rational content, and, on the other hand, be open to what other agents actually have to say about morality.

As the eleventh volume in the New Directions in Cognitive Science series (formerly the Vancouver Studies in Cognitive Science series), this work promises superb scholarship and interdisciplinary appeal. It addresses three areas of current and varied interest: common sense, reasoning, and rationality. While common sense and rationality often have been viewed as two distinct features in a unified cognitive map, this volume offers novel, even paradoxical, views of the relationship. Comprised of outstanding essays from distinguished philosophers, it considers (...) what constitutes human rationality, behavior, and intelligence covering diverse areas of philosophy, psychology, cognitive science, and computer science. Indeed, it is at the forefront of cognitive research and promises to be of unprecedented influence across numerous disciplines. (shrink)

A great challenge of the twenty-first century is the danger of conflict between persons, peoples, and cultures, among and within societies. In _A Common Human Ground_, Claes Ryn explores the nature of this problem and sets forth a theory about what is necessary for peaceful relations to be possible. Many in the Western world trust in “democracy,” “capitalism,” “liberal tolerance,” “scientific progress,” or “general enlightenment” to handle this problem. Although each of these, properly defined, may contribute toward alleviating (...) disputes, Ryn argues that the problem is much more complex and demanding than is usually recognized. He reasons that, most fundamentally, good relations among individuals and nations have moral and cultural preconditions. What can predispose them to mutual respect and peace? One Western philosophical tradition, for which Plato set the pattern, maintains that the only way to genuine unity is for historical diversity to yield to universality. The implication of this view for a multicultural world would be a peace that requires that cultural distinctiveness be effaced as far as possible and replaced with a universal culture. A very different Western philosophical tradition denies the existence of universality altogether. It is represented today by postmodernist multiculturalism—a view that leaves unanswered the question as to how conflict between diverse groups might be averted. Ryn questions both of these traditions, arguing for the potential union of universality and particularity. He contends that the two need not be enemies, but in fact need each other. Cultivating individual and national particularities is potentially compatible with strengthening and enriching our common humanity. This volume embraces the notion of universality, while at the same time historicizing it. Using wide-ranging examples, Ryn presents a firmly sustained and systematic argument centering on this central issue. His approach is interdisciplinary, discussing not only political ideas, but also fiction, drama, and other arts. Scholarly and philosophical, but not specialized, this book will appeal to general readers as well as intellectuals. (shrink)

Nonmonotonic conditionals (A |∼ B) are formalizations of common sense expressions of the form “if A, normally B”. The nonmonotonic conditional is interpreted by a “high” coherent conditional probability, P(B|A) > .5. Two important properties are closely related to the nonmonotonic conditional: First, A |∼ B allows for exceptions. Second, the rules of the nonmonotonic system p guiding A |∼ B allow for withdrawing conclusions in the light of new premises. This study reports a series of three experiments on (...) reasoning with inference rules about nonmonotonic conditionals in the framework of coherence. We investigated the cut, and the right weakening rule of system p. As a critical condition, we investigated basic monotonic properties of classical (monotone) logic, namely monotonicity, transitivity, and contraposition. The results suggest that people reason nonmonotonically rather than monotonically. We propose nonmonotonic reasoning as a competence model of human reasoning. (shrink)

Nonmonotonic reasoning is often claimed to mimic human common sense reasoning. Only a few studies, though, have investigated this claim empirically. We report four experiments which investigate three rules of SYSTEMP, namely the AND, the LEFT LOGICAL EQUIVALENCE, and the OR rule. The actual inferences of the subjects are compared with the coherent normative upper and lower probability bounds derived from a non-infinitesimal probability semantics of SYSTEM P. We found a relatively good agreement of human reasoning and (...) principles of nonmonotonic reasoning. Contrary to the results reported in the ‘heuristics and biases’ tradition, the subjects committed relatively few upper bound violations (conjunction fallacies). (shrink)

Logic, considered as a technical discipline inaugurated by Aristotle and typically represented by the variety of the modern logical calculi, constitutes a clarification and refinement of a conviction and practice present in common sense, that is, the fact that humans believe that truth can be acquired not only by immediate evidence, but also by means of arguments. As a first step logic can be seen as a “descriptive” record of the main forms of the arguments present in common (...) sense, but the fact that some of these patterns can actually allow for the derivation of false consequences from true premises imposes the task of making explicit what patterns correspond to a “correct reasoning” and what not. At this point logic appears endowed with a “normative” characteristic. This amounts to saying that logical calculi are intended to adequately mirror the intuitive notion of “logical consequence” and in this sense they cannot be totally arbitrary or conventional, but must satisfy certain basic requirements such as the conditions of soundness and of semantic completeness. In such a way they are “judged” according to the fundamental requirements present at the level of common sense and appear as “idealizations” of the kinds of reasoning practiced in common sense. For this reason also several kinds of logical calculi are fully justified since they make explicit in an idealized form the concrete ways of reasoning that are imposed by the particular domain of reference of the discipline in which they are used and which are basically recognized in common sense.

This paper answers the philosophical contentions defended in Horsten and Welch . It contains a description of the standard format of adaptive logics, analyses the notion of dynamic proof required by those logics, discusses the means to turn such proofs into demonstrations, and argues that, notwithstanding their formal complexity, adaptive logics are important because they explicate an abundance of reasoning forms that occur frequently, both in scientific contexts and in common sense contexts.

In comparing humans and animals, we may use humans as the standard to measure animals, or conversely, animals as the standard to measure humans. While most philosophers have adopted the former approach, David Hume is among those few who use the comparison with animals as means to throw light on human nature. I focus on Hume’s treatment of human and animal reason. The cognitive processes and states that Hume holds to be common to humans and animals (...) may be called situated, that is, embedded in the process of guiding actions that is actually going on and consequently relative to the agent’s current position in space-time. Hume’s treatment of causal reasoning underlines the centrality of situated cognition in the workings of human, as well as animal minds. Taking situated reasoning and beliefs as the paradigm of human cognition enables us to look from an alternative point of view, at the features supposedly unique to human cognition, like the use of general words and concepts. Thus we can find a confirmation of the practical import of general words and concepts in Hume’s account of the obligation of promises, where words play an essential role in extending our control over objects and actions beyond what is present and particular into what is absent or not yet actualized. This is also a confirmation of how deeply our cognitive abilities in general are rooted in our practical needs. (shrink)

Santayana's Life of Reason, published in five books from 1905 to 1906, ranks as one of the greatest works in modern philosophical naturalism. Acknowledging the natural material bases of human life, Santayana traces the development of the human capacity for appreciating and cultivating the ideal. It is a capacity he exhibits as he articulates a continuity running through animal impulse, practical intelligence, and ideal harmony in reason, society, art, religion, and science. The work is an exquisitely (...) rendered vision of human life lived sanely. In this first book of the work, Santayana provides an account of how the human animal develops instinct, passion, and chaotic experience into rationality and ideal life. Inspired by Aristotle's De Anima, Darwin's evolutionary theory, and William James's The Principles of Psychology, Santayana contends that the requirements of action in a hazardous and uncertain environment are the sources of the development of mind. More specifically, instinct and imagination are crucial to the emergence of reason from chaos. Separating himself from the typical thought of the time by his recognition of the imagination, Santayana in this volume offers extensive critiques of various philosophies of mind, including those of Kant and the British empiricists. This Critical Edition, volume VII of The Works of George Santayana, includes a chronology, notes, bibliography, textual commentary, lists of variants, and other tools useful to Santayana scholars. The other four books of the volume include Reason in Society, Reason in Religion, Reason in Art, and Reason in Science. (shrink)

British psychologists have been at the forefront of research into human reasoning for 40 years. This article describes some past research milestones within this tradition before outlining the major theoretical positions developed in the UK.

We identify a common theme that is emerging in all these approaches, that is, the problem of explaining how prior general knowledge affects reasoning. In our concluding comments we outline the (...) challenges for future research posed by this problem. (shrink)

The subject of human acts has been one of the controversial topics of kalām since the first centuries of Islam. A lot of concerning human acts –from divine attributes to divine decree and destiny, from the issue of good and evil (ḥusn and Qubḥ) to the boundaries of the reasoning, from the accountability with impossible things to the rational accountability, from the topics of substance and accident to causality- has been said and written in the history of Islamic (...) tought. In this study, the subject was discussed especially within the scope of man’s on his own action in connection with the divine knowledge, will, and power. On this issue, the Muʻtazila argues that human beings are independent in doing their good and evil acts with the power that God has given to them because of His will and wisdom, and that the evil actions that they have done cannot be associated with the divine attributes in any way. Sunnī theologians assert that God creates human actions through man’s orginated power. They also arguethat evil acts are not independent of the Divine Creation although human beings are the reason of evil in terms of thier acquisition (kasb) and will (irāda). Nevertheless, the representetives of the Sunnī kalām (Asharites and Māturīdis) differ on their account of acquisition, which expresses man’s agency in his acts. In contrary to the Mātūrīdiya, the Ashʻariya holds that acquisition is a created act of God. On the other hand, the Mashshai (peripatetic) philosophers, who are opposed by teologians on some issues such as divine attributes and the working of activity/acts in nature, consider human’s actions part of the eternal chain of cause-effect that emanate (al fayḍ) from the First Principle. However, according to them, every link of this chain is formed by the divine providence (al-ināyah). They also attribute morally evil acts not to the First Principle which is complete (tām) and full good (hayr), but to agents in the cause-effect chain. In summary, according to both teologians and philosophers, the ultimate source of human acts is the divine will and power. The acts that are morally or religiously evil, are not independent of man’s will. Thus, human beings are accountable for their actions. Philosophers and teologians, who agree on these issues, have explained their views and build their opinions on different concepts and principles. They have shown a very different attitude in their discourse and secondary principles, while all of them basically try to express the same idea. This difference has revealed within the frame of the following questions: Is man’s accountability for his actions because of his created power or will? Can evil actions, which are willed by human beings and therefore created by God, attributed to Him? Does the fact that the world emanates from God, the First Principle, due to His knowledge and essence, necessitate Him to be a willless and ineffective agent, and therefore to be a cause cause that has no effect on man's actions?Although teologians and philosophers have put forward different views in the context of the answers to these questions, they agree on the issues we have mentioned above. As this study shows, there is actually a common purpose in this subject, man’s actions, which causes deep divisions between theologians and philosophers in Islamic history. Primary sources of the study are the basic texts of the schools mentioned above. Additionally, the study were limited to the subject the effect of human on acts. It consists of two parts: the main part and the conclusion part. In the main section, the approaches of schools were examined from two aspects, in in terms of divine attribute and human effectiveness, and in the conclusion section, the common purposes behind the discussions were determined.

In his defense of innateness in New Essays on Human Understanding (1704), Leibniz attributes innateness to concepts and principles which do not originate from the senses rather than to the ideas that we are born with. He argues that the innate concepts and principles can be known in two ways: through reason or natural light (necessary truths), and through instincts (other innate truths and principles). In this paper I will show how theoretical and moral reasoning differ from each (...) other in Leibniz, and compare moral reasoning and instincts as sources of knowledge in his practical philosophy. As the practical instincts are closely related to pleasure and passions, which are by nature cognitive, my emphasis will be on the affective character of instinctive moral action and especially deliberation which leads to moral action. I will argue that inclinations arising from moral instinct, which lead us to pleasure while avoiding sorrow, can direct our moral action and sometimes anticipate reasoning when conclusions are not readily available. Acting by will, which is related to moral reasoning, and acting by instincts can lead us to the same moral knowledge independently, but they can also complement each other. To illustrate the two alternative ways to reach moral knowledge, I will discuss the case of happiness, which is the goal of all human moral action for Leibniz. (shrink)

Nonmonotonic logics allow—contrary to classical (monotone) logics— for withdrawing conclusions in the light of new evidence. Nonmonotonic reasoning is often claimed to mimic human common sense reasoning. Only a few studies, though, have investigated this claim empirically. system p is a central, broadly accepted nonmonotonic reasoning system that proposes basic rationality postulates. We previously investigated empirically a probabilistic interpretation of three selected rules of system p. We found a relatively good agreement of human reasoning and principles of (...) nonmonotonic reasoning according to the coherence interpretation of system p. This study reports an experiment on the cautious monotonicity Rule and its “incautious” counterpart that is not contained in system p, namely the monotonicity Rule. In accordance with our previous results, the data suggest that people reason nonmonotonically: the subjects in the cautious monotonicity condition infer significantly tighter intervals close to the coherence interpretation of system p compared with the subjects in the incautious monotonicity condition where rather wide (and hence non-informative) intervals are inferred.

The aim of this dissertation is to create a naturalistic philosophical picture of creative capacities that are specific to our species, focusing on artistic ability, religious reflection, and scientific study. By integrating data from diverse domains within a philosophical anthropological framework, I have presented a cognitive and evolutionary approach to the question of why humans, but not other animals engage in such activities. Through an application of cognitive and evolutionary perspectives to the study of these behaviors, I have sought to (...) provide a more solid footing for philosophical anthropological discussions of uniquely human behavior. In particular, I have argued that art, religion and science, which are usually seen as achievements that are quite remote from ordinary modes of reasoning, are subserved by evolved cognitive processes that serve functions in everyday cognitive tasks, that arise early and spontaneously in cognitive development, that are shared cross-culturally, and that have evolved in response to selective pressures in our ancestral past. These mundane cognitive processes provide a measuring rod with which we can assess a diversity of cultural phenomena; they form a unified explanatory framework to approach human culture. I have argued that we can explain uncommon thoughts in terms of interactions between common minds. This dissertation is subdivided into four parts. Part I outlines the problem of human uniqueness, examining theories on how humans conceptualize the world, and what their mental tool box looks like. Part II discusses the evolutionary and cognitive origins of human artistic behavior. Part III focuses on the cognitive science of religion, especially on how it can be applied to the reasoning of theologians and philosophers of religion. Part IV considers the cognitive basis of scientific practice. (shrink)

Charles Hodge engaged the leading thinkers of his day to defend the human ability to know God. This involved him in affirming the importance of both orthodoxy and piety in the life of a Christian. His work involved expanding on the insights of the Westminster Confession of Faith as it applied to the theory of salvation and the role of Christ.

It is now commonplace in many jurisdictions for judges to refer to the decisions of the courts of foreign jurisdictions when interpreting domestic human rights guarantees. But there has also been a persistent undercurrent of scepticism about this trend, and the emergence of a growing debate about its appropriateness. This issue is of particular relevance in jurisdictions that have relatively recently incorporated human rights provisions that are significantly judicially enforced. In the UK, a reconsideration of the use of (...) comparative judicial decisions in human rights cases is therefore particularly timely. The interpretation of the Human Rights Act 1998 will bring with it the issue of how far British courts will (and/or should) use jurisprudence from other countries in order to help in arriving at decisions on the interpretation of the Act. This article raises for debate, therefore, the meaning and significance of national judges» citation of judgments from other jurisdictions as part of their reasoning in cases with a significant human (or constitutional) rights aspect. Several questions are identified and explored in an attempt to consider various aspects of the general phenomenon. These include empirical questions (how far does it happen, and where?), jurisprudential questions (can we identify criteria that help explain why it does or does not happen?), and normative questions (is it legitimate?). A review of the existing literature is undertaken with a view to determining how far scholars have succeeded in answering these questions. The article concludes that significant gaps exist in our understanding of the phenomenon and raises for discussion the methodologies that may be appropriate for addressing the phenomenon in the future.

In this book, Jeanine Grenberg argues that everything important about Kant's moral philosophy emerges from careful reflection upon the common human moral experience of the conflict between happiness and morality. Through careful readings of both the Groundwork and the Critique of Practical Reason, Grenberg shows that Kant, typically thought to be an overly technical moral philosopher, in fact is a vigorous defender of the common person's first-personal encounter with moral demands. Grenberg uncovers a notion of phenomenological (...) experience in Kant's account of the Fact of Reason, develops a new a reading of the Fact, and grants a moral epistemic role for feeling in grounding Kant's a priori morality. The book thus challenges readings which attribute only a motivational role to feeling; and Fichtean readings which violate Kant's commitments to the limits of reason. This study will be valuable to students and scholars engaged in Kant studies. (shrink)

In the first ever commentary on the Groundwork, one of Kant’s earliest critics, Gottlob August Tittel, argues that the categorical imperative is not a new principle of morality, but merely a new formula. This objection has been unjustly neglected in the secondary literature, despite the fact that Kant explicitly responds to it in a footnote in the second Critique. In this paper I seek to offer a thorough explanation of both Tittel’s ‘new formula’ objection and Kant’s response to it, as (...) well as illustrate its significance. I argue that the objection is in fact the third step in a line of argument that Tittel presents in his commentary, and that the objection is best understood within this context. I analyze Kant’s response in the second Critique footnote line-by-line so as to show that Kant both clarifies that it was never his aim to offer a new principle, but only ‘establish’ the principle that common human reason already implicitly employs. Furthermore, I show that Kant uses the opportunity to clarify the sense in which the categorical imperative is a ‘formula [Formel]’, namely as a representation of a complicated and abstract principle, like the moral law, in a way that is easier to understand and apply. I conclude by illustrating the fourth step in Tittel’s line of argument, which makes the overall significance of the ‘new formula’ objection clear: for Tittel, the problem is not that Kant seems to be offering merely a new formula, but that the categorical imperative lacks a foundation.

Should a Christian ethic endorse an individual’s right against torture? If so, how should its reasoning take into account considerations of common security? To answer these questions, this article first compares the early Christian ‘just war’ tradition’s pre-liberal reasoning about the ethics of harming with that of the liberal philosopher, David Rodin. It then deploys the fruits of this comparison—especially the contingency of a right against harm (partly upon social obligation), and the distinction between natural moral rights and positive (...) legal ones—in an examination of what makes torture wrong and when. Dissenting from the views of Jeremy Waldron and Jean Porter, the article concludes that a positive legal right against torture and aggressive interrogation should be granted—even though morally right cases of the latter might occur.

I shall be dealing, throughout this book, with a set of related problems: the relationship between morality and reasoning in general, the way in which moral reasoning is properly to be carried on, and why morality is not arbitrary. The solutions to these problems come out of the same train of argument. Morality is not arbitrary, I shall argue, because the acceptance of certain qualities of character as virtues and the rejection of others as vices is forced on us by (...) the co-operative basis of human life. The co-operation in human life is unavoidable; the alternative is a literal Hobbesian state of nature, and that is impossible. It is not that co-operation between people is a good thing or even a very good thing; it is simply unavoidable in human life, and it is impossible unless the qualities of character counted as virtues are encouraged and are at least fairly common. The possibility of human life presupposes a theory of human nature, and working out that theory of human nature is the main job of moral philosophy. These virtues or qualities of character or attitudes lead us towards a theory of reasons. A person with a sense of justice is a person inclined to accept certain sorts of facts as reasons for acting, and if the virtues are presupposed by human life then the acceptance of those sorts of facts as reasons for acting is presupposed by human life. A condition of the life of reasoning beings (a more accurate term here than 'human beings') is that moral reasons are reasons for acting and are at the very basis of reasoning. And from this it follows that properly conducted moral reasoning is ultimately guided by the virtues rather than ultimately guided by a set of rules. (shrink)

The author poses a question: which of the two fundamental, constitutional values – common good or human dignity – can be considered to be the cornerstone, the unifying value in the Constitution of the Republic of Poland from 1997. The paper shows the crucial reasons for accepting each of these values as primary and also presents the underlying relationships between these values . The prominence of a given value for defining the aim of the constitution and the legal (...) order based on it was accepted as the most important aspect for determining the order of primacy. In respect of the direct aims of activities of public authorities and more broadly – of the aims of subjects whose activities are defined by the constitution – the primary value should be common good understood as certain social conditions of life which support human development. It defines the space in which other constitutional values, also human dignity, are integrated. Human dignity, however, the primary value defining human being, gives the reason why human development is a first and autonomous aim of the constitutional order. In this respect dignity has priority before common good. -/- Autor stawia pytanie o to, którą z fundamentalnych wartości konstytucyjnych – dobro wspólne czy godność człowieka – można uznać za wartość pierwszą i stanowiącą podstawę spójności aksjologicznej Konstytucji RP z 2 kwietnia 1997 roku.

Diagrams figure prominently in human reasoning, especially in science. Cognitive science research has provided important insights into the inferences afforded by diagrams and revealed differences in the reasoning made possible by physically instantiated diagrams and merely imagined ones. In scientific practice, diagrams figures prominently both in the way scientists reason about data and in how they conceptualize explanatory mechanisms. To identify patterns in data, scientists often graph it. While some graph formats, such as line graphs, are used widely, (...) scientists often develop specialized formats designed to reveal specific types of patterns and not infrequently employ multiple formats to present the same data, a practice illustrated with graph formats developed in circadian biology. Cognitive scientists have revealed the spatial reasoning and iterative search processes scientists deploy in understanding graphs. In developing explanations, scientists commonly diagram mechanisms they take to be responsible for a phenomenon, a practice again illustrated with diagrams of circadian mechanisms. Cognitive science research has revealed how reasoners mentally animate such diagrams to understand how a mechanism generates a phenomenon. (shrink)

This paper describes the topological aspect of a logic-based, artificial intelligence approach to formalising the qualitative description of spatial properties and relations, and reasoning about those properties and relations. This approach, known as RCC theory, has been under development for several years at the University of Leeds. The main rationale for this project is that qualitative descriptions of spatial properties and relationships, and qualitative spatial reasoning, are of fundamental importance in human thinking about the world: even where quantitative spatial (...) data are most important, they must be attached to the components of a perceived spatial structure if we are to make use of them. RCC theory covers other qualitative aspects of spatial description and reasoning, but the topological properties and relations of spatially extended entities are fundamental to our work. The topological formalisms used by mathematicians are, in general, not well suited to the task of formalising the kinds of ‘common-sense’ or ‘everyday’ qualitative spatial description and reasoning which are our primary interest. Nevertheless, we must come to grips with the concepts of topology as practised by mathematicians if we are not to risk constantly ‘reinventing wheels’. (shrink)

This volume centers on debates about how far moral judgments bind across traditions and epochs. Nowadays such debates appear especially volatile, both in popular culture and intellectual discourse: although there is increasing agreement that the moral and political criteria invoked in human rights documents possess cross-cultural force, many modern and postmodern developments erode confidence in moral appeals that go beyond a local consensus or apply outside a particular community. Often the point of departure for discussion is the Enlightenment paradigm (...) of a common morality, in which it is assumed that certain unchanging beliefs inhere in the structure of human reason. Whereas some thinkers continue to defend this paradigm, others modify it in diverse ways without abandoning entirely the attempt to address a universal audience, and still others jettison virtually all of its distinguishing features. Exhibiting a range of positions Western participants take in these debates, this volume seeks to advance the substance of the debates themselves without prejudging the outcome. Rival assessments of the Enlightenment paradigm are offered from various philosophical and theological points of view. In addition to the editors, the contributors include Robert Merrihew Adams, Annette C. Baier, Alan Donagan, Margaret A. Farley, Alan Gewirth, David Little, Richard Rorty, Jeffrey Stout, and Lee H.

Abstract:Humans often comply with social norms, but the reasons why are disputed. Here, we unify a variety of influential explanations in a common decision framework, and identify the precise cognitive variables that norms might alter to induce compliance. Specifically, we situate current theories of norm compliance within the reinforcement learning framework, which is widely used to study value-guided learning and decision-making. This framework offers an appealingly precise language to distinguish between theories, highlights the various points of convergence and divergence, (...) and suggests novel ways in which norms might penetrate our psychology.

The notions of “rational” and “reasonable” have much in common but are not synonymous. Conducting a review of the literature points to (at least) two distinct but related ideas as well as a middle “grey” area. This paper investigates and compares some characterizations of these notions and defends the view that focusing on reasonableness is best for those interested in human instances of reasoning and argumentation.

The Victorian age was a period in which Christian Orthodoxy was undermined by new and emerging forms of reasoned inquiry. The commonly-held view amongst historians is that the intellectual life in the era was composed of two hostile camps; those who defended Christian Orthodoxy and those who championed the new sciences. The received view is that, when faced by the new fields of reasoned inquiry, Christianity’s prominence within British intellectual life and discourse went into terminal decline. The intention of this (...) article is to demonstrate that there was a middle ground between the two camps. In particular, this article aims to demonstrate that attempts were made to reconcile Christianity with the findings of the emerging forms of reasoned inquiry. This will be achieved through providing an examination of T. H. Green’s theory of Human Agency. Green he was one of the most prominent philosophers of the Victorian age. Through his theory of human agency, Green consciously engaged in the debate that existed between theistic Christianity and the emerging forms of reason inquiry of the time. (shrink)

This paper describes the topological aspect of a logic-based, artificial intelligence approach to formalising the qualitative description of spatial properties and relations, and reasoning about those properties and relations. This approach, known as RCC theory, has been under development for several years at the University of Leeds. The main rationale for this project is that qualitative descriptions of spatial properties and relationships, and qualitative spatial reasoning, are of fundamental importance in human thinking about the world: even where quantitative spatial (...) data are most important, they must be attached to the components of a perceived spatial structure if we are to make use of them. RCC theory covers other qualitative aspects of spatial description and reasoning, but the topological properties and relations of spatially extended entities are fundamental to our work. The topological formalisms used by mathematicians are, in general, not well suited to the task of formalising the kinds of ‘common-sense’ or ‘everyday’ qualitative spatial description and reasoning which are our primary interest. Nevertheless, we must come to grips with the concepts of topology as practised by mathematicians if we are not to risk constantly ‘reinventing wheels’. (shrink)

The 2-c debate between the Greek Apologists and the pagan Graeco-Roman tradition is multifaceted and complex. Common ground can be found in the mutual commitment to reason as a reflection of the Logos: Reason, or the rationality embedded in things. Logos, in this picture, is participated in through a performance of reasoning whose reliability is presupposed in the discourses of both debating parties—contextualized here as the presupposition that the deliverances and activity of reason are reliable for (...) uncovering reality. Presuppositions are starting points and driving principles of inquiry, here designated as first principles. One presuppositional conflict between 2-c Greek Apologists, taking the apologetic works of Justin, Theophilus, Athenagoras, and the author of the Epistle to Diognetus as a sample, and the pagan tradition, taking Celsus as its 2-c culmination, is over how to justify the commitment to reason’s reliability in the above sense. My claim in this paper is twofold: first, that the pagan position is unable in principle to demonstrate the reliability of its own reasoning and that all such inquiry is circular: it is always a further question for the pagan why reasoning reveals reality. I propose that what would count as an answer to this challenge is a metaphysical ‘fit’ between human embodiment and reality. And second, that the Apologists avoid this unhappy conclusion by committing themselves to the embodiment of Reason in Jesus—that the embodied act of human reasoning reveals reality because Reason itself is embodied in the same way. The upshot is that unless the pagan abandons his position, he is trapped in a circular epistemology and cannot encounter the Christian witness on its own terms. (shrink)

The unfinished nature of Beauchamp and Childress’s account of the common morality after 34 years and seven editions raises questions about what is lacking, specifically in the way they carry out their project, more generally in the presuppositions of the classical liberal tradition on which they rely. Their wide-ranging review of ethical theories has not provided a method by which to move beyond a hypothetical approach to justification or, on a practical level regarding values conflict, beyond a questionable appeal (...) to consensus. My major purpose in this paper is to introduce the thought of Bernard Lonergan as offering a way toward such a methodological breakthrough. In the first section, I consider Beauchamp and Childress’s defense of their theory of the common morality. In the second, I relate a persisting vacillation in their argument regarding the relative importance of reason and experience to a similar tension in classical liberal theory. In the third, I consider aspects of Lonergan’s generalized empirical method as a way to address problems that surface in the first two sections of the paper: (1) the structural relation of reason and experience in human action; and (2) the importance of theory for practice in terms of what Lonergan calls “common sense” and “general bias.”.

One of the goals of medicine is to improve well-being, in line with the principle of beneficence. Likewise, scientists claim that the goal of human embryonic stem cell research is to find treatments for diseases. In hESC research, stem cells are harvested from a 5-day-old embryo. Surplus embryos from infertility treatments or embryos created for the sole purpose of harvesting stem cells are used in the research, and in the process the embryos get destroyed. The use of human (...) embryos for research purpose raises ethical concern. In this context, the religious leaders play the role to be the moral compass and “reality check” to engage with the public. In Malaysia, the Ministry of Health has outlined the Guidelines for Stem Cell Research and Therapy, reflecting on Islamic principles. Since there has not been much focus on the viewpoints of other faiths in Malaysia, this study attempts to explore the ethical guiding principles deliberated by religious leaders from the Buddhist, Hindu and Catholic traditions and identify if there is a common ground between the mainstream religious views and principles of medical ethics, in relation to hESC research. Eleven religious leaders representing the Buddhist, Hindu and Catholic traditions were interviewed. Interestingly, though reasoning of religious leaders came from different angles, their underlying concerns revolve around the values of “do no harm” and “intention to save lives”. These values are also the key principles in medical ethics. The findings are applied to answer the question as to whether religious and medical guiding principles can co-exist and complement in ethical decision-making, without compromising the values.

The common-sense view that reasons guide us in thought and action and that humans are essentially reason-responsive animals is increasingly under attack by defenders of what one can call the Rationalisation View, which emphasises that we typically rationalise actions and judgements that are based on intuition rather than reasoning. This article defends the former view of human Reason, partly by replying to prominent advocates of the latter, partly by proposing accounts of reflective reasoning and rationalisation that (...) bring to light a common, underappreciated feature: they both involve the capacity to see considerations as reasons. This capacity, the author conjectures, should be the starting point for investigating the faculty we call ‘Reason’, its evolutionary origin, and the (ir)rationality of different kinds of thought associated with it.

Defined and formalized several decades ago, widely used in philosophy and game theory, the concept of common knowledge is still considered as problematic, although not always for the right reasons. I suggest that the epistemic status of a group of human agents in a state of common knowledge has not been thoroughly analyzed. In particular, every existing account of common knowledge, whether formal or not, is either too strong to fit cognitively limited individuals, or too weak (...) to adequately describe their state. I provide a realistic definition of common knowledge, based on a formalization of David Lewis’ seminal account and show that it is formally equivalent to probabilistic common belief. This leads to a philosophical analysis of common knowledge which answers several common criticisms and sheds light on its nature. (shrink)

Tarski’s conceptual analysis of the notion of logical consequence is one of the pinnacles of the process of defining the metamathematical foundations of mathematics in the tradition of his predecessors Euclid, Frege, Russell and Hilbert, and his contemporaries Carnap, Gödel, Gentzen and Turing. However, he also notes that in defining the concept of consequence “efforts were made to adhere to the common usage of the language of every day life.” This paper addresses the issue of what relationship Tarski’s analysis, (...) and Béziau’s further generalization of it in universal logic, have to reasoning in the everyday lives of ordinary people from the cognitive processes of children through to those of specialists in the empirical and deductive sciences. It surveys a selection of relevant research in a range of disciplines providing theoretical and empirical studies of human reasoning, discusses the value of adopting a universal logic perspective, answers the questions posed in the call for this special issue, and suggests some specific research challenges.

Humans have used arguments for defending or refuting statements long before the creation of logic as a specialized discipline. This can be interpreted as the fact that an intuitive notion of “logical consequence” or a psychic disposition to articulate reasoning according to this pattern is present in common sense, and logic simply aims at describing and codifying the features of this spontaneous capacity of human reason. It is well known, however, that several arguments easily accepted by (...) class='Hi'>common sense are actually “logical fallacies”, and this indicates that logic is not just a descriptive, but also a prescriptive or normative enterprise, in which the notion of logical consequence is defined in a precise way and then certain rules are established in order to maintain the discourse in keeping with this notion. Yet in the justification of the correctness and adequacy of these rules commonsense reasoning must necessarily be used, and in such a way its foundational role is recognized. Moreover, it remains also true that several branches and forms of logic have been elaborated precisely in order to reflect the structural features of correct argument used in different fields of human reasoning and yet insufficiently mirrored by the most familiar logical formalisms.
