This volume reaches beyond the controversy surrounding the teaching and learning of evolution in the United States, specifically in regard to the culture, politics, and beliefs found in the Southeast. The editors argue that despite a deep history of conflict in the region surrounding evolution, there is a wealth of evolution research taking place—from biodiversity in species to cultural evolution and human development. In fact, scientists, educators, and researchers from around the United States have found their niche in the South, (...) where biodiversity is high, culture runs deep, and the pace is just a little bit slower.

Neural cell adhesion molecules of the immunoglobulin superfamily are important components of the network of guidance cues and receptors that govern axon growth and guidance during development. For neural cell adhesion molecule L1, the combined application of human genetics, knockout mouse technology, and cell biology is providing fundamental insight into the role of L1 in mediating neuronal differentiation. Disease-causing mutations as well as mouse models of L1 disruption can now be used to examine the relevance of L1 binding specificities and (...) signal transduction pathways that have been observed in vitro.

All too often, the requirements for actionability and accountability of data infrastructures are conceptualised as incompatible and leading to a trade-off situation where increasing one will unavoidably decrease the other. Through a comparative analysis of two data infrastructures used to share genomic data about the SARS-COV-2 virus, we argue that making data actionable for knowledge development involves a commitment to ensuring that the data in question are representative of the phenomena being studied and accountable to data subjects and users. This (...) in turn presupposes that: (1) enough data are contributed by a wide and diverse set of relevant sources; (2) mechanisms of feedback and inclusion are set up to ensure that data contributors can participate data governance and interpretation, thereby helping to adequately contextualise data; and (3) accountability extends to the ways in which data infrastructures are run, financed and positioned vis-à-vis the communities they are meant to serve. Such a model of data sharing can only work on the understanding that data do not need to be easily accessible to be actionable; rather, actionability depends on the responsiveness and accountability of data infrastructures, and the efforts invested in ensuring open communication among contributors.

It is sometimes proposed that killing or harming abortion providers is the only logically consistent position available to opponents of abortion. Since lethal violence against morally responsible attackers is normally viewed as justified in order to defend innocent parties, pro-lifers should also think so in the case of the abortion doctor and so they should act to defend the unborn. In our paper, we defend the mainstream pro-life view against killing abortion doctors. We argue that the pro-life view can, in (...) various ways, reject the assumption that defensive violence to save innocent individuals is always permissible. Now even if that assumption is accepted, we contend that defensive violence against abortion doctors still is not justified. Drawing on Frances Kamm’s work, we contend that there are structural similarities between abortion and letting someone die who needs your help to stay alive; and we argue that it is impermissible to kill those who kill in order to avoid giving life-saving aid.

This volume, which is rooted in biogeophysical studies, addresses conceptions of political action in the Anthropocene and the tension between a desire to accomplish the Promethean project of modernity and a post-Promethean approach. This work explores the idea of ​​an anthropological mutation of political consolidation from a “post-Promethean togetherness”, to creating the capacity to act together. The political thinking of the human condition developed by Hannah Arendt is important here as a resource for thinking about humanity in terms of human (...) adventure. This has three dimensions: hubris, the world and coexistence referring respectively to the logic of profit of the homo oeconomicus, the logic of responsibility of the homo collectivus and the logic of the hospitality of the homo religatus. The intellectual and political attitude outlined in this book is an extension of critical theory: the work also puts forward a critique of what poses a problem in our relationship to the world and suggests how to overcome it, the ultimate goal being social transformation. The author propose an uprising and an anthropological consolidation of politics based on the revitalization that is brought about by the sharing of a conviviality both between humans and with what is non-human. The identification of conviviality as an educational paradigm to survive the Anthropocene gives us the much needed reason for hope despite this heritage of the Anthropocene. In addition to Arendtian thinking, this critical theory for the Anthropocene draws on the political thinking of several contemporary authors including Maurice Bellet, Hartmut Rosa, Andreas Weber, Dominique Bourg, and Christian Arnsperger. This volume is of interest to researchers in the Anthropocene. (shrink)

According to recent commentators like Paul Guyer, Kant agrees with Hume's Dialogues Concerning Natural Religion that physico-theology can never provide knowledge of God and that the concept of God, nevertheless, provides a useful heuristic principle for scientific enquiry. This paper argues that Kant, far from agreeing with Hume, criticizes Hume's Dialogues for failing to prove that physico-theology can never yield knowledge of God and that Kant correctly views Hume's Dialogues as a threat to, rather than an anticipation of, his own (...) view that the concept of God provides a useful heuristic principle for science. The paper concludes that Kant's critique of physico-theology reflects Kant's deep dissatisfaction with Hume's manner of argumentation and suggests that Kant's attempt to provide a more successful critique of physico-theology merits continued philosophical attention.

We describe an approach to textual inference that improves alignments at both the typed dependency level and at a deeper semantic level. We present a machine learning approach to alignment scoring, a stochastic search procedure, and a new tool that finds deeper semantic alignments, allowing rapid development of semantic features over the aligned graphs. Further, we describe a complementary semantic component based on natural logic, which shows an added gain of 3.13% accuracy on the RTE3 test set.

O genocídio indígena esteve presente na ditadura civil-militar brasileira (1964-1985), assim como em todos os períodos após as invasões portuguesas de 1500. A partir do uso dos ideais coloniais e da estrutura capitalista, as políticas de desenvolvimentismo com as invasões às terras indígenas culminaram no genocídio que foi protagonizado pelo Exército Brasileiro. Segundo a Comissão Nacional da Verdade, mais de 8.350 indígenas foram mortos durante o período de 1946 a 1988, número este que pode ser bem maior, dado que o (...) levantamento da CNV contabilizou apenas 10 povos –, dentre eles, 2.650 do povo Waimiri Atroari. O principal evento em que as mortes dos Waimiri Atroari ocorreram foi a construção da BR-174 que liga Manaus a Boa Vista. A Comissão Nacional da Verdade, estabelecida com a Lei 12.528/2011, teve o objetivo de examinar e esclarecer as graves violações de direitos humanos praticadas no período de 1946 a 1988. Por meio do campo teórico-metodológico da História do Tempo Presente foi possível analisar os temas elencados para apontar as feridas ainda abertas na história e memória nacional. (shrink)

The aim of this investigation is to explore the role of argumentation schemes in enthymeme reconstruction. This aim is pursued by studying selected cases of incomplete arguments in natural language discourse to see what the requirements are for filling in the unstated premises and conclusions in some systematic and useful way. Some of these cases are best handled using deductive tools, while others respond best to an analysis based on defeasible argumentations schemes. The approach is also shown to work reasonably (...) well for weak arguments, a class of arguments that has always been difficult to analyze without the principle of charity producing a straw man.

We develop conceptions of arguments and of argument types that will, by serving as the basis for developing a natural classification of arguments, benefit work in artificial intelligence. Focusing only on arguments construed as the semantic entities that are the outcome of processes of reasoning, we outline and clarify our view that an argument is a proposition that represents a fact as both conveying some other fact and as doing so wholly. Further, we outline our view that, with respect to (...) arguments that are propositions, (roughly) two arguments are of the same type if and only if they represent the same relation of conveyance and do so in the same way. We then argue for our conceptions of arguments and argument types, and compare them to alternative positions. We also illustrate the need for, and some of the strengths of, our approach to classifying arguments through an examination of aspects of two prominent and recent attempts to classify arguments using argumentation schemes, namely those of M. Kienpointner and D. Walton. Finally, we clarify how our conception of arguments and of argument types can assist in developing an exhaustive classification of arguments. (shrink)

This book aims to answer two main questions about Aristotle’s theory of causality and causal explanation, especially in relation to natural science: (1) How does he answer the main philosophical questions about causes to which he thinks his predecessors’ answers are flawed? (2) How do his answers bear on the main questions we confront in thinking about causality in general? The texts that deal with causality directly are analyzed against the background of his criticisms of his predecessors and his broader (...) views about explanation, highlighting their theoretically important commitments. This allows us to reveal the conceptual architecture of his theory. The basic theory is then applied to two questions about causality, one metaphysical and one epistemological. The metaphysical question is how to account for the relation between causes and what they cause, in light of a fundamental tension between different desiderata for causal explanations. Aristotle’s answer is pluralistic: he does not think that there is one metaphysical relationship between causes and what they cause even within a given mode of causality. The epistemological question asks how we grasp causes, and grasp them in a way that yields scientific understanding. Aristotle’s answer is again a pluralist one: metaphysically different phenomena demand different cognitive resources, and some are more accessible than others. Nevertheless, there is a discernible path from simpler to more sophisticated types of cognitive grasp on causality, in such a way that Aristotle can plausibly satisfy the epistemological constraints he thinks his predecessors cannot. Aristotle thus aims to provide a non-reductionist account of causality that still leaves room for a substantive conception of understanding in natural science. (shrink)

There is a growing trend among some physicians, psychiatrists, bioethicists, and other mental health professionals not to treat physician-assisted suicide (PAS) as suicide. The grounds for doing so are that PAS fundamentally differs from other suicides. Perhaps most notably, in 2017 the American Association of Suicidology argued that PAS is distinct from the behavior that their organization seeks to prevent. This paper compares and contrasts suicide and PAS in order to see how much overlap there is. Contrary to the emerging (...) view that emphasizes their differences, I argue that there is significant overlap such that we ought not to separate PAS into its own category, making it diverge from how we think about and address suicide more generally. I start by examining several prominent theories of suicide and argue that PAS fits squarely within them. I then examine several apparent differences between PAS and other kinds of suicide and argue that these differences are merely apparent or they do not justify treating PAS as a fundamentally different kind of thing from suicide.

How does Hume determine what qualities of the mind count as virtues and what qualities count as vices? By what standard, for example, does Hume dismiss the so-called “monkish virtues”? Hume’s commentators have proposed various possibilities for the standard of virtue, among them the general point of view and the usefulness/agreeableness of qualities. I consider the case for these standards and argue that Hume contends ultimately that consensus decides controversial questions about the status of virtues and vices. I try especially (...) to show that while the usefulness of any quality is not a means by which we can identify virtues or vices, it can be relevant to moral evaluations in so far as it influences what people tend to approve of.

Situationists contend that virtue ethics is empirically inadequate. However, it is my contention that there is much confusion over what “empirical adequacy” or “empirical inadequacy” actually means in this context. My aim in this paper is to clarify the meanings of empirical adequacy in order to see to what extent virtue ethics might fail to meet this standard. I argue that the situationists frequently misconstrue the empirical commitments of virtue ethics. More importantly, depending on what we mean by empirical adequacy, (...) either virtue ethics has no need to be empirically adequate or where it does have such a need, the psychological evidence fails to show that it is empirically inadequate. An additional contribution the paper intends to make is to provide a more detailed discussion of the explanatory nature of virtue ethics. (shrink)

In this article I argue that vanity, the desire for and delight in the favorable opinion of others, plays a fundamental role in Hume's account of moral motivation. Hume says that vanity and virtue are inseparable, though he does not explicitly say how or why this should be. I argue that Hume's account of sympathy can explain this alliance. In resting moral sentiment on sympathy, Hume gives a fundamental role to vanity as it becomes either a mediating motive to virtue (...) or else strengthens the otherwise weak motive of moral sentiment.

The debate about physician-assisted suicide has long been entwined with the nature of the doctor–patient relationship. Opponents of physician-assisted suicide insist that the traditional goals of medicine do not and should not include intentionally bringing about or hastening a patient’s death, whereas proponents of physician-assisted suicide argue that this practice is an appropriate tool for doctors to relieve a patient’s suffering. In this article, I discuss these issues in light of the relevance of a Christian account of the doctor–patient relationship. (...) I argue that Christians typically object to assist suicide independently of the doctor–patient relationship. I argue that a focus on the Christian virtues of charity, compassion, and humility helps to explain why doctors should not assist their patients in suicide. (shrink)

The relevance of double effect for end-of-life decision-making has been challenged recently by a number of scholars. The principal reason is that opioids such as morphine do not usually hasten death when administered to relieve pain at the end of life; therefore, no secondary “double” effect is brought about. In my article, I argue against this view, showing how the doctrine of double effect is relevant to the administration of opioids at the end of life. I contend that the prevailing (...) view suffers from a misunderstanding of the nature of double effect, which includes application to risking a grave harm. (shrink)

Recent models in quantum cosmology make use of the concept of imaginary time. These models all conjecture a join between regions of imaginary time and regions of real time. We examine the model of James Hartle and Stephen Hawking to argue that the various no-boundary attempts to interpret the transition from imaginary to real time in a logically consistent and physically significant way all fail. We believe this conclusion also applies to quantum tunneling models, such as that proposed by Alexander (...) Vilenkin. We conclude, therefore, that the notion of emerging from imaginary time is incoherent. A consequence of this conclusion seems to be that the whole class of cosmological models appealing to imaginary time is thereby refuted. (shrink)

It is a commonplace that imagination is heterogeneous: we need to draw a series of cross-cutting distinctions even to begin any serious general discussion of the range of activities we take to be typical instances. The nature of the heterogeneity being exhibited is usually left unclear, however, and thus so are its consequences both for our understanding of imagination and for assessing certain challenges such as reductionism. Here it is argued that we can accept heterogeneity while recognizing important forms of (...) unity among the various kinds of imaginative activity. Four distinct but compatible strategies are considered, three of which have historical precedents in Aristotle’s and Hegel’s work. These proposals yield an interesting and plausible answer to the problem raised by heterogeneity, and have consequences for how we should respond to it. They share a plausible framework for thinking about the relationships among the various activities contemporary thinkers take to involve imagination. However, there are some ways in which deploying them is not straightforward, given some differences between modern approaches and older ones, and they conflict with a common thought about the epistemic status of imagination.

Aristotle opens his discussion of time in Physics 4.10-14 with a puzzle, an argument which purports to show that time does not exist, since its only parts – the past and future – do not exist. He does not discuss the puzzle again, and so we are left with the question of how he would or could solve it. A full solution would involve not only a justification of realism about time, but also an account of why the puzzle arises, (...) what must be corrected to prevent it from arising, and how much of our pre-theoretical picture of time survives these adjustments. This paper argues that we can provide such a solution by (i) distinguishing between two ways of being committed to the reality of past, present, and future, and (ii) examining Aristotle’s remarks in Physics 4.12 on the notions of being in time and being surrounded by time.

In lieu of an abstract, here is a brief excerpt of the content:arrêt sur visagefrom Hatred of Translation1Nathanaël (bio)or else isolated in silence—Danielle Collobert, Ça des motsIn the language of film there are often extraordinary divergences between English and French, which prove at times to be irreconcilable.2 If this tendency toward discrepancy is true of translation as a rule, it reveals itself to be particularly true in the case of this work in translation. Danielle Collobert's Recherche,3 rendered as Research, in (...) which the search of re-search must be read as detachable, with emphasis on its repetitive motion—but also in its slide from substantive to predicate (search>searches)—makes salient such divergences, through the implied camera movement panning over the evacuated faces of A and B and the marked distances especially that define the space of their bodies, in proximity and in remove, as though the text were annotating a form of recusal that is implicit in the spaces of desire to which their mortiferous movements owe everything; an intimacy of anticipated death, and seizure, from which the camera extracts movements of degradation through violent stillness.Indeed the term still here is adopted to render the French arrêt, proposing a false equivalency between the (film) still and its seemingly concordant locution, the arrêt (sur image). These are "attested" terms that reveal something of the contexts in which each seeks to function. In Recherche Collobert limits herself [End Page 138] to the use of arrêt sur, designating in each instance a specific detail on which the camera is to stop. "Stop" of course is one of the translations of the lone substantive "arrêt," which also implies "arrest" (from the verb arrêter), replete with its juridical (enforceable/enforcible) intent.4One might just as readily translate "arrêt sur" as "stop at," stopping at nothing to achieve the irresistible demands of such a transitive language that subverts its own objectivity through a persistent preference for passive forms, abdicating one's responsibility to the law in abject deference to its capital aims. Regimens of grammar are coincident with regimens of power now as always.5More than one frontier has now been crossed, and reading the three works6 gathered by Françoise Morvan under the title Expériences (experiments and/ or experiences) in this so-called America is a serious transposition indeed in which the sands of north-western France adjoining the virulent Atlantic, may readily allow themselves to be supplanted by an imagined far-ouest of burnt deserts shimmering with radioactive particulate, under some gun. These are voided investigations that succeed only in subtracting the body from its criminality—a condemnation of ages pressed into moments, a crime committed to each and every one.Meurtre (Murder), the title of Collobert's first acknowledged work,7 is just as operative in these cinematic and radiophonic works; indeed, it can be read as a mot d'ordre for her entire oeuvre,8 and with which its entire topography is suffused. The stills of Recherche and "Polyphonie" attest to this, as does the recurrence of the isolate arrêt, whether in its designation of a bus stop or a pause in action (breaks in the fight, for example, between B and the man on the dock), toppling into the near untranslatable arrêts in the plural, stops, which invites, again, a transitive reading rather than the congealment of the plural substantive, and this, in keeping with the stares that transfix and bore into the faces verging on the dunes. The polysemic displacement of arrêt is such that the cumulative effect of its multiply transposed sense is that of a filmstrip caught in a projector, and it isn't clear whether the image is held or whether it is caught in the mechanism; in either case, the reader is among those held captive by a language that forbids release, burrowing instead, more deeply, into a thickeningly menacing interiority with its inscription of fear similar to that elicited by the perceived approach of the beast in Kafka's "The Burrow." The time of exposure holds the permanent promise of such a threat. [End Page 139]Nathanaël Nathanaël... (shrink)

Depuis plusieurs décennies, s’est instaurée « une nouvelle ère » pour le corps, caractérisée par une évolution des pratiques médicales, mais aussi et surtout par le développement de nouvelles utopies.

The third author has shown that Shelah's eventual categoricity conjecture holds in universal classes: class of structures closed under isomorphisms, substructures, and unions of chains. We extend this result to the framework of multiuniversal classes. Roughly speaking, these are classes with a closure operator that is essentially algebraic closure (instead of, in the universal case, being essentially definable closure). Along the way, we prove in particular that Galois (orbital) types in multiuniversal classes are determined by their finite restrictions, generalizing a (...) result of the second author. (shrink)

Though not often discussed as such, Gore Vidal's Myra Breckinridge is a work of queer utopianism. Myra herself is an entrancing figure—a self-created goddess who is determined to save humanity by abolishing gender itself. That her efforts ultimately fail is a testament to the queerness of her utopianism. Using Lee Edelman's discussion of “reproductive futurism” and José Esteban Muñoz's insights into the queerness of utopianism, this article analyzes the ways in which Myra Breckinridge channels both hopeful and destructive urges as (...) a way of imagining a counter-narrative to the human catastrophe represented by the atomic bomb and the threat of overpopulation.

Recent work at the intersection of moral philosophy and the philosophy of psychology has dealt mostly with Aristotelian virtue ethics. The dearth of scholarship that engages with Hume’s moral philosophy, however, is both noticeable and peculiar. Hume's Moral Philosophy and Contemporary Psychology demonstrates how Hume’s moral philosophy comports with recent work from the empirical sciences and moral psychology. It shows how contemporary work in virtue ethics has much stronger similarities to the metaphysically thin conception of human nature that Hume developed, (...) rather than the metaphysically thick conception of human nature that Aristotle espoused. It also reveals how contemporary work in moral motivation and moral epistemology has strong affinities with themes in Hume’s sympathetic sentimentalism. (shrink)

Next SectionIt is commonly proposed that artifacts cannot be understood without reference to human intentions. This fact, I contend, has relevance to the use of artifacts in intentional action. I argue that because artifacts have intentions embedded into them antecedently, when we use artifacts we are sometimes compelled to intend descriptions of our actions that we might, for various reasons, be inclined to believe that we do not intend. I focus this argument to a specific set of artifacts, namely, medical (...) devices, before considering an extended application to emergency contraceptive devices. Although there is some debate about whether emergency contraception has an abortifacient effect, I argue that if there is an abortifacient effect, then the effect cannot normally be a side effect of one’s action.

Aristotle thinks that we understand something when we know its causes. According to Aristotle but contrary to most recent approaches, causation and explanation cannot be understood separately. Aristotle complicates matters by claiming that there are four causes, which have come to be known as the formal, material, final, and efficient causes. To understand Aristotelian causation and its relationship to explanation, then, we must come to a precise understanding of the four causes, and how they are supposed to be explanatory. Aristotle’s (...) discussion of the causes, however, is compact, and he typically presents them without arguing for them. He thus leaves us with a number of questions, ranging from the highly specific to the highly general. One question in particular has captured the attention of scholars and philosophers over the last century, and it has had a strong influence on recent treatments of the four causes – namely, whether we are right to understand Aristotle as committed to a plurality of kinds of causation, or rather a plurality of kinds of explanation. Sometimes the question is raised as one of whether it would be more accurate to speak of the four ‘becauses’ rather than the four ‘causes’. This worry is highly general, and there are in fact several ways in which it might be formulated; nonetheless, it is important to clarify the precise nature of the problem, and the possible ways of responding to it. At issue is not just whether Aristotle’s notions are sufficiently like the modern notion of causation to be relevant to our concerns, but, more importantly, whether the distinctions he draws are ultimately metaphysical or epistemological in character.

This paper attempts to give a complete and coherent account of how Hume’s moral psychology can explain the cultivation of moral character. I argue that the outcome of a fully formed moral character is an agent who strengthens her calm moral sentiments into settled principles of action. I then take up the question of how the process of strengthening moral sentiments might occur, rejecting the possibilities of sympathy, “reflection,” and “resolution” because either they are too weak or else they make (...) the passion violent, preventing the essential calm nature of moral sentiments. I next argue that custom and the non-moral motives of pride and the love of fame play the critical roles in character formation. Custom can be considered as both the process of education, whereby certain impressions are habitually and formally inculcated into us by educators, and the process of experience in society and conversation, whereby we learn to associate pleasure with the virtues and pain with the vices. In both these processes, Hume implicitly appeals to certain non-moral motives, especially pride and the love of fame, in order to launch the effects of custom. (shrink)

This book provides a systematic analysis of many common argumentation schemes and a compendium of 96 schemes. The study of these schemes, or forms of argument that capture stereotypical patterns of human reasoning, is at the core of argumentation research. Surveying all aspects of argumentation schemes from the ground up, the book takes the reader from the elementary exposition in the first chapter to the latest state of the art in the research efforts to formalize and classify the schemes, outlined (...) in the last chapter. It provides a systematic and comprehensive account, with notation suitable for computational applications that increasingly make use of argumentation schemes. (shrink)

One finds in the systems of natural languages some explicit means of elaborating not only upon the directness of the causal relationship believed to exist between two events X and Y (i.e. some means of specifying just how inevitably event X gives or gave rise to event Y), but also some manner of indicating just who or what is understood to be the primary instigator of the caused event. The goal of the present paper is to explore these notions in (...) detail and arrive at a formal, logic-based means of capturing them. (shrink)

Hume says that sympathy is the source of our moral feeling of approval for useful qualities. But does Hume give the same psychological explanation of our approval of immediately agreeable qualities as he does to our approval of useful qualities? Does he trace our moral approbation of immediately agreeable qualities to sympathy? Some commentators, including Rachel Cohon and Don Garrett, argue that he does not. Let us call this view the ‘narrow view’ of sympathy in contrast to the ‘wide view’ (...) of sympathy, which holds that sympathy is required for every moral sentiment. There is indeed some apparent textual evidence in Hume’s work that seems to support the narrow view. My aim in this paper is to examine that evidence and show how it is merely apparent, in particular by showing how a number of passages can be and are misread. I thus want to argue indirectly for the wide view. (shrink)

We have reason to think that a fundamental goal of natural science, on Aristotle’s view, is to discover the essence-specifying definitions of natural kinds—with biological species as perhaps the most obvious case. However, we have in the end precious little evidence regarding what an Aristotelian definition of the form of a natural kind would look like, and so Aristotle’s view remains especially obscure precisely where it seems to be most applicable. I argue that if we can get a better understanding (...) of how the forms of natural kinds are or come to be known, and how they make things intelligible, we can get a better appreciation of the nature of form in general, as well as solve certain puzzles about form and definition.

Central to Aristotle's metaphysics and epistemology is the claim that ‘aitia’ – ‘cause’ – is “said in many ways”, i.e., multivocal. Though the importance of the four causes in Aristotle's system cannot be overstated, the nature of his pluralism about aitiai has not been addressed. It is not at all obvious how these modes of causation are related to one another, or why they all deserve a common term. Nor is it clear, in particular, whether the causes are related to (...) one another as species under a single genus, such that there is a univocal definition of ‘aitia’ which applies to all of them, or whether Aristotle means to assert that the four causes are homonyms. It is argued here that although there are strong reasons to group the four causes together, there are also powerful considerations on the side of homonymy. It is further argued that the four causes are more closely tied to the ontological theory of categories and predication than is often recognized. As a result, we can reconcile the competing demands of unity and plurality by taking one mode of causation, the formal cause, as basic, and accounting for the other modes with reference to it, in the manner of so-called pros hen homonyms.
