Many have claimed that epistemic rationality sometimes requires us to have imprecise credal states (i.e. credal states representable only by sets of credence functions) rather than precise ones (i.e. credal states representable by single credence functions). Some writers have recently argued that this claim conflicts with accuracy-centered epistemology, i.e., the project of justifying epistemic norms by appealing solely to the overall accuracy of the doxastic states they recommend. But these arguments are far from decisive. In this essay, we prove some (...) new results, which show that there is little hope for reconciling the rationality of credal imprecision with accuracy-centered epistemology. (shrink)

This paper addresses the ongoing debate over the relation between belief and credence. A proposal is made to reverse the currently predominant order of analysis, by taking belief as conceptually basic and credence as the phenomenon to be clarified. In brief, the proposal is to explicate an agent’s credence in a proposition P as the agent’s tendency toward believing P. Platitudinous as this reduction may seem, it runs counter to all of the major positions in the debate, including the Threshold (...) View, the Certainty View as conventionally understood, Dualism, Eliminativism, as well as Credence Primitivism. Section 1 gives an overview on the current state of the debate. Section 2 considers unsuccessful predecessors of the proposed belief-first approach to credence. Section 3 motivates and lays out the basics of a conceptual framework for thinking about doxastic states that characterizes such states in terms of two formally independent dimensions, one pertaining to the agent’s tendency toward believing P, the other to the level of resilience with which the agent manifests that tendency. Against this backdrop, it is argued in Sect. 4 that the present reduction satisfies a set of standard, theoretically neutral criteria of adequacy for theories of credence, at least once they are purged of a quite common conflation of tendency and resilience. Section 5 argues against all of the above competing accounts. (shrink)

This volume analyses ancient and medieval theories of intentionality in various contexts: perception, imagination, and intellectual thinking.

Historians of philosophy often credit Descartes, Locke, and other seventeenth-century authors with having introduced one of the most vexing problems into epistemology: the problem of mental representations. For these authors claimed that our knowledge of the external world is always mediated by mental representations, so that we have immediate access only to these representations, the ideas in our mind. As is well known, this “veil-of-ideas epistemology” gave rise to a number of skeptical questions. How can we be certain that our (...) ideas are accurate representations of the external world? And how can we be sure that there is an external world at all if we never have immediate access to it? In his highly original and provocative study, Robert Pasnau argues that these questions are not distinctively modern. They were already asked and thoroughly discussed by medieval authors: “much of what is often taken to be novel in the seventeenth and eighteenth centuries was already old news by the fourteenth”. According to Pasnau, it was Thomas Aquinas who introduced some form of representationalism into epistemology by developing the species-theory, and it was first Peter John Olivi and later William Ockham who attacked this theory, insisting that we always have immediate cognitive access to the external world.

In this article, it will be argued that tolerance is not necessarily a political or ethical, but rather an abstract attitude that can be applied to many different dimensions of normative evaluation. More specifically, it will be argued that there are genuinely intellectual forms of tolerance that are epistemically motivated and that need to be assessed on purely epistemic grounds. To establish this claim, an abstract characterization of tolerance will be applied to the epistemic phenomenon of disagreement in order to (...) develop a specific conception of tolerance that picks out a genuinely intellectual attitude towards recognized disagreement. Since the attitude that is picked out by this conception is very popular and widespread, an epistemology of tolerance would be of great significance to our intellectual practice. (shrink)

This paper addresses questions of universality related to ontological engineering, namely aims at substantiating (negative) answers to the following three basic questions: (i) Is there a ‘universal ontology’?, (ii) Is there a ‘universal formal ontology language’?, and (iii) Is there a universally applicable ‘mode of reasoning’ for formal ontologies? To support our answers in a principled way, we present a general framework for the design of formal ontologies resting on two main principles: firstly, we endorse Rudolf Carnap’s principle of logical (...) tolerance by giving central stage to the concept of logical heterogeneity, i.e. the use of a plurality of logical languages within one ontology design. Secondly, to structure and combine heterogeneous ontologies in a semantically well-founded way, we base our work on abstract model theory in the form of institutional semantics, as forcefully put forward by Joseph Goguen and Rod Burstall. In particular, we employ the structuring mechanisms of the heterogeneous algebraic specification language HetCasl for defining a general concept of heterogeneous, distributed, highly modular and structured ontologies, called hyperontologies. Moreover, we distinguish, on a structural and semantic level, several different kinds of combining and aligning heterogeneous ontologies, namely integration, connection, and refinement. We show how the notion of heterogeneous refinement can be used to provide both a general notion of sub-ontology as well as a notion of heterogeneous equivalence of ontologies, and finally sketch how different modes of reasoning over ontologies are related to these different structuring aspects.

Many late medieval Aristotelians assumed that a natural substance has several substantial forms in addition to matter as really distinct parts. This assumption gave rise to a unity problem: why is a substance more than a conglomeration of all these parts? This paper discusses Francisco Suárez’s answer. It first shows that he rejected the idea that there is a plurality of forms, emphasizing instead that each substance has a single form and hence a single structuring principle. It then examines his (...) account of the relationship between matter and form. While accepting the thesis that these two parts are really distinct entities, he claimed that there is a special “mode of union” that binds them together. With this account, he defended the essential unity of a natural substance, but he transformed the program of Aristotelian metaphysics: not substances, but entities and modes inside them, are now the basic building blocks of reality.

This study illuminates how a cross-sector social partnership legitimizes itself toward multiple internal and external stakeholders. Within a single-case study design, we collected retrospective and real time data on the partnership between Deutsche Post DHL and The United Nations Office for the Coordination of Humanitarian Affairs. Within this partnership, Deutsche Post DHL provides corporate volunteers that support disaster response after natural disasters on a pro bono basis. The main objects that needed legitimacy as well as the audiences from which legitimacy (...) was mainly sought changed over time. In addition, we identified legitimation work as occurring across objects, audiences, and time. Thus, we introduce legitimation work as the purposeful effort of the legitimacy seeker to avoid certain issues while ensuring other issues that are of importance to the conferrer of legitimacy. These findings contribute to micro-level considerations within institutional theory which view legitimacy as socially constructed between legitimacy seeker and conferrer. Hence, we add another perspective on legitimation to the previously existing conceptualizations of legitimacy as a deterministic consequence of institutionalization. (shrink)

Throughout its history, the renowned Kaṭha Upaniṣad has often been described as being both incoherent and contradictory. The aim of this paper is to show to what purpose the text was created. To this end, it discusses the connection of the three paths to salvation depicted in the text, viz. the Agnicayana, the Upaniṣadic method of self-knowledge, and yoga. The first part retraces how in the Upaniṣads, the Agnicayana was transformed into a non-material or mental ritual and linked with self-knowledge. (...) The second part analyses how the various salvation goals could be related to each other. First, the authors redefined the Agnicayana’s salvation goal, heaven, to make it identical with liberation. Secondly, they introduced self-knowledge and yoga as alternative and equally powerful means to the same end. In practice, however, the new and world-negating methods were implied to be superior to the costly ritual from which they had drawn their authority. Thus, the authors of the Upaniṣad were more concerned with showing continuity between different religious approaches than upholding consistency of content. (shrink)

It seems quite natural that we have cognitive access not only to things around us, but also to our own acts of perceiving and thinking. How is this access possible? How is it related to the access we have to external things? And how certain is it? This paper discusses these questions by focusing on Francisco Suárez’s theory, which gives an account of various forms of access to oneself and thereby presents an elaborate theory of consciousness. It argues that Suárez (...) clearly distinguishes between first-order sensory consciousness and second-order intellectual consciousness. Moreover, Suárez attempts to explain the unity of consciousness by referring to a single soul with hierarchically ordered faculties that is responsible both for first-order and for second-order consciousness.

Many different approaches to describing the players’ knowledge and beliefs can be found in the literature on the epistemic foundations of game theory. We focus here on non-probabilistic approaches. The two most prominent are the so-called Kripkeor Aumann- structures and knowledge structures (non-probabilistic variants of Harsanyi type spaces). Much of the recent work on Kripke structures has focused on dynamic extensions and simple ways of incorporating these. We argue that many of these ideas can be applied to knowledge structures as (...) well. Our main result characterizes precisely when one type can be transformed into another type by a specific type of information update. Our work in this paper suggest that it would be interesting to pursue a theory of “information dynamics” for knowledge structures (and eventually Harsanyi type spaces). (shrink)

Toy models are highly idealized and extremely simple models. Although they are omnipresent across scientific disciplines, toy models are a surprisingly under-appreciated subject in the philosophy of science. The main philosophical puzzle regarding toy models concerns what the epistemic goal of toy modelling is. One promising proposal for answering this question is the claim that the epistemic goal of toy models is to provide individual scientists with understanding. The aim of this article is to precisely articulate and to defend this (...) claim. In particular, we will distinguish between autonomous and embedded toy models, and then argue that important examples of autonomous toy models are sometimes best interpreted to provide how-possibly understanding, while embedded toy models yield how-actually understanding, if certain conditions are satisfied. _1_ Introduction _2_ Embedded and Autonomous Toy Models _2.1_ Embedded toy models _2.2_ Autonomous toy models _2.3_ Qualification _3_ A Theory of Understanding for Toy Models _3.1_ Preliminaries and requirements _3.2_ The refined simple view _4_ Two Kinds of Understanding with Toy Models _4.1_ Embedded toy models and how-actually understanding _4.2_ Against a how-actually interpretation of all autonomous toy models _4.3_ The how-possibly interpretation of some autonomous toy models _5_ Conclusion.

We study two logics of knowledge and belief stemming from the work of Stalnaker, omitting positive introspection for knowledge. The two systems are equivalent with positive introspection, but not without. We show that while the logic of beliefs remains unaffected by omitting introspection for knowledge in one system, it brings significant changes to the other. The resulting logic of belief is non-normal, and its complete axiomatization uses an infinite hierarchy of coherence constraints. We conclude by returning to the philosophical interpretation (...) underlying both models of belief, showing that neither is strong enough to support a probabilistic interpretation, nor an interpretation in terms of certainty or the “mental component” of knowledge.

This paper provides the first systematic philosophical analysis of an increasingly important part of modern scientific practice: analogue quantum simulation. We introduce the distinction between `simulation' and `emulation' as applied in the context of two case studies. Based upon this distinction, and building upon ideas from the recent philosophical literature on scientific understanding, we provide a normative framework to isolate and support the goals of scientists undertaking analogue quantum simulation and emulation. We expect our framework to be useful to both (...) working scientists and philosophers of science interested in cutting-edge scientific practice. (shrink)

Toy models are highly idealized and extremely simple models. Although they are omnipresent across scientific disciplines, toy models are a surprisingly under-appreciated subject in the philosophy of science. The main philosophical puzzle regarding toy models is that it is an unsettled question what the epistemic goal of toy modeling is. One promising proposal for answering this question is the claim that the epistemic goal of toy models is to provide individual scientists with understanding. The aim of this paper is to (...) precisely articulate and to defend this claim. In particular, we will distinguish between autonomous and embedded toy models, and, then, argue that important examples of autonomous toy models are sometimes best interpreted to provide how-possibly understanding, while embedded toy models yield how-actually understanding, if certain conditions are satisfied.

PurposeSince the 1980s we have witnessed a soaring “extra-therapeutic” use of psycho-pharmacology. But there is also an increasing interest in invasive methods of neuroenhancement that can be subsumed under the term “brain engineering”. The present article aims to identify key issues raised by those forms of neuro-technical enhancement (e.g., deep brain stimulation, brain-computer interfaces, memory chips, neurobionic interventions). First it distinguishes different forms of neuroenhancement, then describes features of those methods and finally discusses their ethical implications.MethodsThe article is based on (...) an in-depth literature study and an ethical assessment of the current and emerging forms of neuroenhancement.ResultsFrom a medical and normative perspective, psycho-pharmacological enhancement and nonpharmacological enhancement by brain engineering demonstrate considerable differences. Many arguments in favour of nonpharmacological enhancement fall short, for they fail to sufficiently consider the medical, anthropological and socio-cultural context. In many respects unsecured use is confronted with considerable risks.ConclusionsResearch on invasive forms of neuroenhancement partly takes place in the fields of (nano-)technology and military, to which health care experts and medical ethicists do not have easy access. This raises the danger of misjudging trends and developmental tendencies. Thus medicine and medical ethics must a priori thematize the goals and risks linked to these questions as well as participate discursively right from the beginning. (shrink)

Definition of the problem: In Germany, the dissection rate of the deceased is distinctly lower than in many other European countries. Although critics of autopsies use to put forward ethical objections and religious scruples, neither the Christian church nor piety stand opposite to the practise of autopsies.Arguments: From an ethical point of view, there are numerous arguments for an increase in the number of autopsies. It can be shown that not only the deceased, his relations and the physicians but also (...) the population as a whole could take advantage of a higher percentage of dissections. In Germany, law authorities put much more emphasis on the regulation of birth and origin of life than on problems concerning dying and death of human beings. Legal obstacles and tendentious reporting by the mass media are serious reasons for the poor popularity of dissections of the corpse.Conclusion: For many reasons, comprehensive and unbiassed information about autopsies, fundamental legislative reforms and an increase of the dissection rate have to be claimed.

When we are asked what the term ‘Socrates’ signifies, we answer spontaneously, I suppose: “the man Socrates.” And when we are asked what the term ‘white’ signifies, we tend to answer: “the color white” or “whiteness.” Although our second answer may be less spontaneous than the first, either because we may have some difficulty in explaining what a color is, ontologically speaking, or because we may be reluctant to commit ourselves to such a controversial thing as whiteness, we may nevertheless (...) be willing to grant that ‘white’ signifies something, however this thing is to be explained in detail. But when we are asked what ‘Socrates is white’ signifies, we might hesitate in giving an answer. Some may say: “Well, this sentence signifies nothing other than Socrates and the color white.” Others may respond: “It signifies Socrates insofar as he is white” or “the fact that Socrates is white.” Still others may reply that there is no answer because only terms signify something; a sentence, on the other hand, does not signify but expresses something or brings something to the understanding.

In response to criticism of empirical or “positive” approaches to corporate social responsibility, we defend the importance of these approaches for any CSR theory that seeks to have practical impact. Although we acknowledge limitations to positive approaches, we unpack the neglected but crucial relationships between positive knowledge on the one hand and normative knowledge on the other in the implementation of CSR principles. Using the structure of a practical syllogism, we construct a model that displays the key role of empirical (...) knowledge in fulfilling a firm’s responsibility to society, paying special attention to the implications of the “ought implies can” dictum. We also defend the importance of one particular class of empirical claims; namely, claims from the field of economics. Even positive economic theory, which is often criticized for endorsing profits rather than values, can cooperate in intriguing ways with non-economic concepts in the implementation of CSR goals.

Spinoza's metaphysical thesis that there is only one substance in the universe but a plurality of modes, each of them falling under an attribute, raises a crucial question. How are modes of thinking, i.e. ideas, related to modes of extension? This paper intends to show that there are at least two answers, depending on an understanding of the equivocal term ‘idea’. If ideas are taken to be mental acts, they are identical with modes of extension. If, however, they are understood (...) in the “objective” way, namely as the conceptual content of mental acts, they correspond to modes of extension. It is argued that this method of disambiguating the term ‘idea’ not only helps to understand Spinoza's famous doctrine of parallelism but that it also provides a solution to two puzzling problems: the possibility of “active affects” and the existence of an eternal mind.

Ockham affirms that a human being consists of three really distinct forms that exist in matter, thus defending a «pluralist» position in the debate about the soul. However, he takes a «unitarist» position with regard to the rational soul, claiming that intellect and will are not really distinct. Why does he not admit a plurality of forms in the rational soul as well? And why does he think that the rational soul as a whole is really distinct from the sensory (...) soul? This paper examines these questions, thus analyzing Ockham’s metaphysics of the soul. It pays close attention to his arguments both for a plurality of forms and for the unity of the rational soul. It argues that Ockham carefully distinguishes between forms that are metaphysical parts of a human being, and faculties that are ways of acting of a specific form. This distinction enables him to reject both a radical unitarism that accepts one single form in a human being, and an excessive pluralism that posits as many forms as there are faculties. (shrink)

In his Tractatus de secundi intentionibus Hervaeus Natalis claims that an intention, taken in the strict sense, is not a mental entity but a thing qua cognized thing having « objective existence ». Peter Aureol agrees with this thesis, but he denies that one needs to introduce, in addition to this « concrete intention », an « abstract intention ». This article gives a preliminary edition of Aureol’s critique, along with a brief analysis of the controversial issues in the Aureol-Hervaeus (...) debate. (shrink)

This paper presents a calculus for mereotopological reasoning in which two-dimensional spatial regions are treated as primitive entities. A first order predicate language ℒ with a distinguished unary predicate c(x), function-symbols +, · and - and constants 0 and 1 is defined. An interpretation ℜ for ℒ is provided in which polygonal open subsets of the real plane serve as elements of the domain. Under this interpretation the predicate c(x) is read as 'region x is connected' and the function-symbols and (...) constants are given their meaning in terms of a Boolean algebra of polygons. We give an alternative interpretation ������ base on the real closed plane which turns out to be isomorphic to ℜ. A set of axioms and a rule of inference are introduced. We prove the soundness and completeness of the calculus with respect to the given interpretation. (shrink)

In recent years, there has been renewed interest in the development of formal languages for describing mereological (part-whole) and topological relationships between objects in space. Typically, the non-logical primitives of these languages are properties and relations such as `x is connected' or `x is a part of y', and the entities over which their variables range are, accordingly, not points, but regions: spatial entities other than regions are admitted, if at all, only as logical constructs of regions. This paper considers (...) two first-order mereotopological languages, and investigates their expressive power. It turns out that these languages, notwithstanding the simplicity of their primitives, are surprisingly expressive. In particular, it is shown that infinitary versions of these languages are adequate to express (in a sense made precise below) all topological relations over the domain of polygons in the closed plane.

This article examines the ethnographic case study in education in the context of policy making with particular emphasis on the practice of research and policy making. The central claim of the article is that it is impossible to establish a transcendental epistemology of the case study on instrumental rationality. Instead it argues for the notion of situated judgement that needs to be made by practitioners in context, practitioners being both researchers and policy makers. In other words, questions about the level (...) of confidence or warrant that can be placed in different sorts of research evidence and findings cannot be answered independently of forming a view about the appropriateness of the policy culture that shapes political decision-making. The article draws a distinction between the general, which is internal to the data as construed by a particular discipline, and the universal, which is the result of embedded human deliberation. This applies to all research findings and not only to case study, although since case study has long had to defend itself against accusations of the lack of generality, it can be a useful starting point for the discussion. This article is not meant to be yet another defence of the case study research genre, although a summary of other defences is offered. Rather it focuses on how use of the case study points to the limits of epistemology as rationality and offers a view of epistemology as ethics. (shrink)
