This paper presents a decision problem called the holiday puzzle. The decision problem is one that involves incommensurable goods and sequences of choices. This puzzle points to a tension between three prima facie plausible, but jointly incompatible claims. I present a way out of the trilemma which demonstrates that it is possible for agents to have incomplete preferences and to be dynamically rational. The solution also suggests that the relationship between preference and rational permission is more subtle than standardly assumed.

There are different kinds of uncertainty. I outline some of the various ways that uncertainty enters science, focusing on uncertainty in climate science and weather prediction. I then show how we cope with some of these sources of error through sophisticated modelling techniques. I show how we maintain confidence in the face of error.

Standard theories in mereotopology focus on relations of parthood and connection among spatial or spatio-temporal regions. Objects or processes which might be located in such regions are not normally directly treated in such theories. At best, they are simulated via appeal to distributions of attributes across the regions occupied or by functions from times to regions. The present paper offers a richer framework, in which it is possible to represent directly the relations between entities of various types at different levels, (...) including both objects and the regions they occupy. What results is a layered mereotopology, a theory which can handle multiple layers (analogous to the layers of a lasagna) of spatially or spatiotemporally coincident but mereologically non-overlapping entities.

We propose an ontological theory that is powerful enough to describe both complex spatio-temporal processes and the enduring entities that participate therein. For this purpose we introduce the notion a directly depicting ontology. Directly depicting ontologies are based on relatively simple languages and fall into two major categories: ontologies of type SPAN and ontologies of type SNAP. These represent two complementary perspectives on reality and employ distinct though compatible systems of categories. A SNAP (snapshot) ontology comprehends enduring entities such as (...) organisms, geographic features, or qualities as they exist at some given moment of time. A SPAN ontology comprehends perduring entities such as processes and their parts and aggregates as they unfold themselves through some temporal interval. We give an axiomatic account of the theory of directly depicting ontologies and of the core parts of the metaontological fragment within which they are embedded. (shrink)

Rational credence should be coherent in the sense that your attitudes should not leave you open to a sure loss. Rational credence should be such that you can learn when confronted with relevant evidence. Rational credence should not be sensitive to irrelevant differences in the presentation of the epistemic situation. We explore the extent to which orthodox probabilistic approaches to rational credence can satisfy these three desiderata and find them wanting. We demonstrate that an imprecise probability approach does better. Along (...) the way we shall demonstrate that the problem of “belief inertia” is not an issue for a large class of IP credences, and provide a solution to van Fraassen’s box factory puzzle. (shrink)

From the time of Descartes a strong tendency emerged to exclude the consideration of metaphysical questions as a necessary step towards developing truly scientific disciplines. Within human geography, positivism had a significant influence in moulding the discipline as "spatial science", resulting in a reductionist vision of humanity. Since the 1970s, in reaction to the limitations of this narrow vision and also to the deterministic perspective of marxism, humanistic approaches became important, but have failed to adequately deal with the exclusion of (...) metaphysical issues. The more recent emergence of postmodern influences within human geography, while being critical of the rigidities associated with Enlightenment thinking, and suggesting a greater tolerance of "difference", appears reluctant to reconsider the exclusion of metaphysics. This paper suggest that such a reconsideration could contribute significantly towards increasing human geography's capacity to help policy makers deal more adequately with some of the major issues facing humanity.

A literary approach to scientific practice: Essay Review of R.I.G. Hughes' _The Theoretical Practices of Physics_.

This paper, as a response to Mark K. Spencer’s, “Perceiving the Image of God in the Whole Human Person” in the present volume, argues in defence of Aquinas’s position that the Imago Dei is limited in the human being to the rational, intellective soul alone. While the author agrees with Spencer that the hierarchical relation between body and soul in the human composite must be maintained while avoiding the various permeations of dualism, nevertheless, the Imago Dei cannot be located in (...) the human body or the principle of the body considered within the body/soul composite without betraying a number of fundamental Thomistic metaphysical principles. Essential to these includes Aquinas’s position that an image of God should image not only the Divine Nature, but also the Trinitarian relations between the Divine Persons. Further, the paper also argues that a phenomenology of sense experience could not, on principle, attain to an image of God in the whole human person within a Thomistic framework generally. (shrink)

This work will argue that Mahāyāna philosophy need not result in endorsement of some cosmic Absolute in the vein of the Advaitin ātman-Brahman. Scholars such as Bhattacharya, Albahari and Murti argue that the Buddha at no point denied the existence of a cosmic ātman, and instead only denied a localised, individual ātman (what amounts to a jīva). The idea behind this, then, is that the Buddha was in effect an Advaitin, analysing experience and advocating liberation in an Advaitin sense: through (...) a rejection of the individual ātman and knowledge (jñāna) of and immersion into the universal ātman-Brahman. I will explore how different religious traditions define and shape the Absolute according to their own religious convictions, illustrating a divergence in conception from the very start, before exploring key differences between the Advaitin conception of the Absolute as put forth by Śaṅkara and as defended by Bhattacharya in The Ātman-Brahman in Ancient Buddhism. I then challenge Bhattacharya’s claims that prajñāpāramitā literature necessarily endorses the ātman-Brahman and that Mahāyāna philosophies reorientate Buddhists towards the truth of the ātman-Brahman. I do this by arguing that there are viable interpretations of Vasubandhu’s Yogācāra and Nāgārjuna’s Madhyamaka that do not advocate such a belief, that prajñāpāramitā literature can be viewed as a project in episteme rather than ontology, and that we need not find a ground of the same sort as the ātman-Brahman in the Buddhist flux of experience. I conclude by showing that whilst Absolutism is a theme in some schools of Buddhism, it need not be – contra Bhattacharya – the conclusion of two major Mahāyāna philosophies. (shrink)

Proclus and Aquinas envision a plurality of divine beings organized hierarchically under the aegis of a first principle: respectively, the One and the henads, and God and His angels. While the differences rule out a wholescale application of Procline henadology to Thomas’ angelology, Aquinas, nevertheless, incorporates Proclus’ henadology into his angelology in two ways. First, Aquinas borrows from Procline henadology when explaining the differences between angels: these can be known in an approximate way from their observable effects. Second, Aquinas incorporates (...) Proclus’ understanding of henadic hierarchy, which focuses on power and activity over ontology, into his conception of angelic hierarchy. (shrink)

In this paper, I first discuss Augustine’s description of time and relate this to Boethius’ explanation of the distinction between time and eternity. I then connect this distinction to Augustine’s understanding of memory as an image of eternity, showing that the analogy between God and the human with reference to time involves a comparison not between eternity and time, but rather, between eternity and a limited experience of eternity within the mind and its distension: time is not the image of (...) eternity, the human mind is, particularly its power of memory (memoria). The accounts of time and eternity of both thinkers provide further evidence for Augustine’s influence on and importance for the thought of Boethius. Both figures describe the past and future as united in the present under the divine purview of God. (shrink)

The theory of granular partitions is designed to capture in a formal framework important aspects of the selective character of common-sense views of reality. It comprehends not merely the ways in which we can view reality by conceiving its objects as gathered together not merely into sets, but also into wholes of various kinds, partitioned into parts at various levels of granularity. We here represent granular partitions as triples consisting of a rooted tree structure as first component, a domain satisfying (...) the axioms of Extensional Mereology as second component, and a mapping (called ’projection’) of the first into the second as a third component. We define ordering relations among granular partitions the resulting structures are called partition frames. We then introduce an axiomatic theory which sentences are interpreted in partition frames.

This paper provides an axiomatic formalization of a theory of foundational relations between three categories of entities: individuals, universals, and collections. We deal with a variety of relations between entities in these categories, including the is-a relation among universals and the part-of relation among individuals as well as cross-category relations such as instance-of, member-of, and partition-of. We show that an adequate understanding of the formal properties of such relations – in particular their behavior with respect to time – is critical (...) for formal ontology. We provide examples to support this thesis from the domain of biomedicine. (shrink)

Although recent scholarship has begun to clarify Porphyry’s position on the first principle in its distinction from that of Plotinus we must be careful not to gloss over the crucial ramifications of Porphyry’s developments. The Plotinian One is beyond Being, and thus beyond all relation and difference. In his attempt to understand how such a principle can be productive of all else that follows from it, Porphyry considers the Plotinian One in both its transcendent and creative aspects, introducing the notions (...) of difference and self-relation within the One itself. Porphyry’s modifications of Plotinus’s doctrine, however, result in a first principle having a character utterly distinct from what Plotinus envisioned, and from what I believe Plotinus would have accepted. Because Porphyry’s first principle is relational, it loses its decisive Plotinian character as absolutely transcendent. This distinction between the first principles of Porphyry and Plotinus has important ramifications for each of their philosophical itineraria, and further strengthens the status of Plotinus within the Neoplatonic tradition. Plotinus is a unique thinker within the Neoplatonic tradition, and we must be careful not to equate Neoplatonism with Plotinus, when in fact, it is Plotinus who against both his own predecessors and successors often stands alone.

This paper examines demonic agency and epistemology in the thought of Augustine. When Augustine claims that demons can “work miracles,” he means this in a specific sense: the actions and intelligence of demons are only miraculous from the standpoint of humans, whose powers of perception and action are limited in relation to those of demons. The character of demons’ bodies and the length of their lives provide abilities beyond what humans possess, but, as natural, created beings, demons adhere to the (...) physical rules of nature. Demons possess neither supernatural powers, nor perfect knowledge. Just as our wonder ceases when we are shown how a magic trick is executed, human astonishment makes way for rational understanding once we comprehend demonic nature. (shrink)

Bryant’s paper, "A Logic of Multiplicities: Deleuze, Immanence, and Onticology," is useful for showing how the historical legacy of hierarchy in its many philosophical forms is still present, important, and, in fact, required even by those such as Bryant who would seek to deconstruct or ignore it. The following response will discuss Bryant’s presentation of his alternative position and throughout point out: a) the straw-man versions of hierarchy that Bryant employs; b) why what Bryant claims to be inherent negatively in (...) hierarchy is not the case; c) how Bryant’s position actually relies upon hierarchy for its own explication, and finally; d) the various principles of hierarchical metaphysics that are required in order to make sense of experience and reality. These latter include the notions that i) there are many kinds of hierarchy; ii) Being and Unity are prior to Multiplicity; iii) relation without substance is incoherent; iv) hierarchy is not inherently tyrannical; v) the distinction between essentially and accidentally ordered causal series is a real and useful one; and vi) the existence of hierarchy is more self evident than is flat ontology.

The future state of the redeemed human being in heaven is difficult, if not impossible, to pin down in this life. Nevertheless, Augustine and Anselm speculate on the heavenly life of the human being, proceeding from certain theological premises gathered from Scripture, and their arguments often both mirror and complement one another. Because Anselm and Augustine hold the premise that human beings in heaven are “equal to the angels” (Luke 20:36), our understanding of the heavenly condition of the human can (...) be illuminated by angelology, and vice-versa; each reveals the nature of the other. The paper examines aspects of the positions of Augustine and Anselm on the original state of the angels, their fall, and their confirmation, and then explores the condition of prelapsarian Adam and the transformation of the elect in order to illuminate how these figures conceive the afterlife. The angelologies (and demonologies) of Augustine and Anselm help one to understand the heavenly goal of human life, how the redeemed state of human beings differs from their original condition in Eden, and why there is no redemption for the fallen angels.

Augustin est bien connu comme défenseur d’une « théorie privative » du mal. On peut lire, par exemple, dans les Confessions que « le mal n’est que la privation du bien, à la limite du pur néant ». Le problème, cependant, avec les théories privatives du mal est qu’elles ne nous offrent pas, généralement, une explication robuste ni de l’activité du mal, ni de son pouvoir à causer des effets bien réels ; effets desquels l’expérience demande, malgré tout, une explication (...) rationnelle. Or, selon Augustin, la privation seule ne permet pas de rendre compte de toutes les manifestations du mal. L’explication privative du mal est, certes, la plus étudiée par la littérature ; mais elle ne constitue qu’une partie du tableau. Cet article veut souligner quatre moments de l’explication du mal qu’Augustin propose : le mal comme privation ; le mal comme parasite par rapport à l’être ; le mal comme perversion de la volonté ; et finalement, le mal comme conflit d’intérêts. Chacun de ces moments éclaire un type de mal, mais aucun ne permet à lui seul de rendre compte du problème. Pris ensemble, cependant, et gardant leurs différences respectives à l’esprit, la réponse d’Augustin à la question du mal se révèle beaucoup plus sophistiquée et exhaustive qu’on ne voudrait souvent l’admettre lorsqu’on se limite uniquement à la théorie de la privation. | : Augustine is well-known for advocating a ‘privation theory’ of evil. In Confessions, he writes that “evil has no existence except as a privation of good, down to that level which is altogether without being.” The problem with privation theories of evil generally is that they do not provide a robust enough account of the activity and power of evil to cause the very real effects for which experience demands a rational explanation. For Augustine, however, privation alone does not fully account for evil in all of its manifestations. The privation account of evil receives much scholarly treatment, but it is only part of the complete Augustinian picture. This paper outlines four accounts of evil in Augustine : evil as privation, as parasitic on being, as perversion of the will, and as conflict of interest. Each deals with a kind of evil, but none alone provides a complete account. Taken together, however, with their differences in mind, Augustine’s explanation of evil is shown to be much more sophisticated and comprehensive than is often recognised when one limits one’s understanding of Augustine’s conception of evil to the privation theory alone.

When do probability distribution functions (PDFs) about future climate misrepresent uncertainty? How can we recognise when such misrepresentation occurs and thus avoid it in reasoning about or communicating our uncertainty? And when we should not use a PDF, what should we do instead? In this paper we address these three questions. We start by providing a classification of types of uncertainty and using this classification to illustrate when PDFs misrepresent our uncertainty in a way that may adversely affect decisions. We (...) then discuss when it is reasonable and appropriate to use a PDF to reason about or communicate uncertainty about climate. We consider two perspectives on this issue. On one, which we argue is preferable, available theory and evidence in climate science basically excludes using PDFs to represent our uncertainty. On the other, PDFs can legitimately be provided when resting on appropriate expert judgement and recognition of associated risks. Once we have specified the border between appropriate and inappropriate uses of PDFs, we explore alternatives to their use. We briefly describe two formal alternatives, namely imprecise probabilities and possibilistic distribution functions, as well as informal possibilistic alternatives. We suggest that the possibilistic alternatives are preferable. -/- . (shrink)

On the origins of British chemical engineering,.

Maureen Donnelly has recently argued that directionalism, the view that relations have a direction, applying to their relata in an order, is unable to properly treat certain symmetric relations. She alleges that it must count the application of such a relation to an appropriate number of objects in a given order as distinct from its application to those objects in any other ordering of them. I reply by showing how the directionalist can link the application conditions of any fixed (...) arity relation, no matter its arity or symmetry, and its converse(s) in such a way that directionalism will yield the correct ways in which it can apply. I thus establish that directionalism possesses the same advantage Donnelly's own account of relations, relative positionalism, has over traditional positionalist accounts of relations, which do not properly treat symmetric relations. I then note some advantages that directionalism has over its closest competitors. This includes Donnelly's relative positionalism, since directionalism is not, like relative positionalism, committed to the involvement of relative properties in every irreducibly relational claim. I close by conceding that, as Donnelly notes, directionalism is committed to the primitive relation of order-sensitive relational application. But I don't find this notion as mysterious as Donnelly does. I conclude that, even if one construes this feature of directionalism as a drawback, the two views are at worst at a draw, other things being equal, since this drawback is mitigated by the advantage directionalism has over relative positionalism.

Maureen Donnelly’s (2016) relative positionalism correctly handles any fixed arity relation with any symmetry such a relation can have, yielding the intuitively correct way(s) in which that relation can apply. And it supplies an explanation of what is going on in the world that makes this the case. But it has at least one potential shortcoming — one that its opponents are likely to seize upon: it can only handle relations with fixed arities. It is unable to handle relations (...) with variable arities. I argue that, all else being equal, relative positionalism ought nonetheless to be preferred to its closest competitors — at least to the extent that the explanation it supplies of relational application is plausible — even though those competitors can handle variable arity relations in addition to fixed arity relations.

It is now well-known that Newton–Cartan theory is the correct geometrical setting for modelling the quantum Hall effect. In addition, in recent years edge modes for the Newton–Cartan quantum Hall effect have been derived. However, the existence of these edge modes has, as of yet, been derived using only orthodox methodologies involving the breaking of gauge-invariance; it would be preferable to derive the existence of such edge modes in a gauge-invariant manner. In this article, we employ recent work by (...) class='Hi'>Donnelly and Freidel in order to accomplish exactly this task. Our results agree with known physics, but afford greater conceptual insight into the existence of these edge modes: in particular, they connect them to subtle aspects of Newton–Cartan geometry and pave the way for further applications of Newton–Cartan theory in condensed matter physics.

It is generally unquestioned that human subjects research review boards should assess the ethical acceptability of protocols. It says so right on the tin, after all: they are explicitly called research ethics committees in the UK. But it is precisely those sorts of unchallenged assumptions that should, from time to time, be assessed and critiqued, in case they are in fact unfounded. John Stuart Mill's objection to suppressers of dissent is instructive here: “If the opinion is right, they are deprived (...) of the opportunity of exchanging error for truth: if wrong, they lose, what is almost as great a benefit, the clearer perception and livelier impression of truth, produced by its collision with error”.1 Andrew Moore and Andrew Donnelly's compelling article, “The job of ‘ethics committees’”, is just this sort of challenge to conventional wisdom, a rejection of the notion that review boards should be considering ethical matters at all.2 If true, we should be substantially reforming our research ethics policies. And if false, rebuttals would help strengthen and ground the otherwise unquestioned assumption of the role of ethics committees. As it happens, I will argue that their critiques fall into the second category. While mistaken, they present a valuable opportunity to clarify the role of ethics committees and their relationship to relevant codes. In particular, I will defend a hybrid account where codes have strict primacy, but leave significant room for review boards …. (shrink)

The concept of bribery is important to our thinking about ethics, especially in professional contexts. This is in no small part due to the thought that, as Seamus Miller has put it, bribery is “a paradigm of corruption”. Business persons and corporate entities are often evaluated by how well they remain free from, root out, and punish corruption – especially in democratic societies. It is a common thought, for example, that a democratic institution ought to be free from corruption. (...) Since bribery is often thought a form – perhaps the paradigmatic form – of corruption, bribery, too, serves as a central concept in our evaluations of business persons and corporate entities. This article will lay out three common elements which together are characteristics of bribery (payment, intention, and wrongdoing), and then briefly illustrate how this conjunction of elements allows for distinguishing between bribery and two other questionable acts often examined in the context of business (grease payment and extortion).

Relatively few authors attempt to assess individuals’ moral responsibility for collective action within organizations. I draw on fairly technical recent work by Seamus Miller, Christopher Kutz, and Tracy Isaacs in the field of collective responsibility to see what normative lessons can be prepared for people considering entry into large hierarchical, compartmentalized organizations like businesses or the military. I will defend a view shared by Isaacs that group members’ responsibility for collective action depends on intentions to contribute to particular collective (...) actions, against Miller and Kutz’s more inculpating standards. Miller and Kutz fail to achieve their goal of articulating a variable standard for measuring individual responsibility within organizations, for reasons suggesting we might not be able to do better with their theoretical commitments than a threshold warning for all potential entrants to be wary of the groups they enter. Isaacs sketches an approach that is more successful at creating a variable standard for assessing high echelon actors; I build on and refine her theory to argue that organization members can be held responsible for their unique interpretations of the organization mission and unique contributions to their role duties. High echelon actors may share personal responsibility for their subordinates’ behavior when they have created the conditions for those actions through their unique orders. (shrink)
