John Baconthorpe (c.1290-1345/8) was the best-known of the Carmelite scholastics in the Middle Ages. This article is a brief study of his solution to the philosophical problem of how the soul may be wholly present in the human body and present whole and undivided in each part. Baconthorpe’s account is of great interest for a number of reasons. He takes issue with one of his fellow Carmelite masters, alerting us to diversity of opinion within that ‘school’. Furthermore, (...) in using terminology and illustrative analogies drawn from terminist logic and the mathematical sciences, Baconthorpe is an important witness to what has been described as the ‘mathematization’ of philosophy and theology in late medieval England. Finally, study of Baconthorpe’s texts provides further evidence of the emergence of the theme of extension in fourteenth-century thought in which we can discern the roots of modern philosophical debate.

When I think that I am now thinking about a rose, are there two mental acts present in the intellect at once, the one direct (about the rose) and the other reflex (about the thought about the rose)? According to a generally accepted principle in medieval psychology, a given mental power cannot have or elicit multiple mental acts at the same time. Hence, many medieval thinkers were unwilling to admit that during such a case of mental reflection there are two (...) acts present in the mind. In this paper, I will look at two theories about mental reflection. According to John Pouilly (1312), during a case of mental reflection there is just one act present in the mind. However, this one act is somehow identical with the direct mental act about the rose that immediately preceded it. If it were not identical with this act, then the sentence "I am thinking that I am thinking about a rose" would be false, since in order for this sentence to be true the direct mental act of thinking about the rose must be present with the reflex mental act of thinking about that act, either as a distinct act, or as somehow identical with it. According to John Baconthorpe (ca. 1325), such a view fails, for even if the reflex mental act were somehow identical with the direct mental act that immediately preceded it, still we would have to admit that it does not coexist with it. On his view, what is sufficient here is that the direct mental· act exist merely as a kind of represented object. Hence, for Baconthorpe, when I think that I am thinking about a rose, there is just one act present in the mind, and this one act has as its content another distinct act (the direct act). However, the direct act does not really exist at the same time as it, although it is represented as if it did. (shrink)

John Baconthorpe canvasses a number of views on the question of the identity of the feature of a divine person that enables that person to become incarnate. The possible features are: the divine essence, the personal property, or the union of both. The views considered are those of Duns Scotus, Durandus of Saint-Pourcain, Peter Auriol, and an Oxonian theologian Walter Burdon, none of whose writing otherwise survive. Baconthorpe's own view is that the union of essence and person (...) is the relevant incarnation-permitting feature. (shrink)

In a seminal article, Simo Knuuttila and Anja Inkeri Lehtinen drew attention to a “curious doctrine” holding that contradictories can be true at the same temporal instant, and identified the major defenders of the doctrine as John Baconthorpe, Landolfo Caracciolo, and Hugh of Novocastro. Normann Kretzmann later asserted as fact the suggestion by Knuuttila and Inkeri Lehtinen that the doctrine comes from a misreading of a passage from Aristotle’s Physics. In fact, a study of the relevant texts reveals (...) that Hugh of Novocastro first elaborated the doctrine by building on the Scotist doctrines of synchronic contingency and simultaneous causation. As these doctrines require at the same instant of time an order of priority and posteriority between possibility and actuality, cause and effect, so, Hugh says, there must be prior and posterior different states of affairs. Landolfo Caracciolo made this doctrine notorious outside the Franciscan convent by using it in his principia debates, directly engaging the circle of Cardinal Iacopo Stefaneschi. John Baconthorpe, the first to cite the Physics passage, did not have any noticeable effect on the development of the doctrine. (shrink)

Hugh of Novocastro, Landolfo Caracciolo, John Baconthorpe, and some other medieval authors argued that there are real contradictions in nature. The background of this early fourteenth-century theory was the Aristotelian question of how to determine the instant of change between p and ~p. The argument was that these are simultaneously true at the temporal instant of change if it is an instant of changing. The author’s aim is to discuss the background of this view in Henry of Ghent’s (...) theory of instantaneous change from potentiality to actuality at that very instant. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Relationship between Theology and Canon Law: Another Context of Political Thought in the Early Fourteenth CenturyTakashi ShogimenPolitical thought and ecclesiology in the early fourteenth century have often been assessed as a series of responses to the question of the relationship between church and state. The conflict between Pope Boniface VIII and Philippe IV at the turn of the thirteenth and fourteenth centuries acutely demonstrated the conflict between the (...) spiritual and temporal powers. The conflict between Pope John XXII and the claimant to the imperial throne, Ludwig of Bavaria, also seems to have formed the historical background against which contemporary intellectuals expounded their political and ecclesiological thought. Two recent excellent textbooks on medieval political thought discussed the early fourteenth century from such a perspective and situated Marsilius of Padua and William of Ockham, along with their papalist adversaries, in this context. 1It is indeed a fair treatment of the period; however, it is not the only legitimate perspective. For instance, an alternative perspective can be developed through an examination of the Poverty Controversy between Pope John XXII and the Franciscans. This dogmatic dispute over the question of whether Christ and the apostles did not own anything individually or communally had a political dimension: it involved discussions on the nature of papal power over the church and resulted in the refinement of the idea of natural rights. 2 The dichotomy [End Page 417] between the papal and imperial camps can also mislead historical interpretation if the fact that each camp was not monolithic is overlooked. Just as Marsilius and Ockham embraced different political views in the alleged imperial camp, so the alleged papal ideologists did not always share the same views. It has even been argued that the doctrines propounded by “papalists” and “anti-papalists” were not irreconcilable but differed only in emphasis. 3 It is easy to see that the problem of Church and State is not the all-embracing concern of the period.What, then, are the possible benchmarks against which we can evaluate the political views of contemporary thinkers? This paper is intended to suggest that there is another context against which political thought and ecclesiology in the early fourteenth century may be assessed: that is, the relationship between theology and canon law. The contemporary polemicists’ view on the role that theology and canon law should play in an ecclesiastical dispute such as the Poverty Controversy largely determined their political or ecclesiological perspectives. To show this, I should like to compare, in the context of the poverty dispute, the ecclesiological views of two theologians in the so-called “papalist” and “anti-papalist” camps respectively: Guido Terreni and John Baconthorpe on the one hand, and William of Ockham and Michael of Cesena on the other. The comparison between Terreni and Baconthorpe will elucidate clearly that their contrasting attitude toward the role of canon law in contemporary ecclesiastical disputes determined the paradigms of their ecclesiologies, resulting in two entirely different ecclesiologies, save the fact that they were both aimed at defending the position of Pope John XXII on Franciscan poverty. The comparison between Ockham and Michael of Cesena will reveal how their contrasting views on the nature of the Poverty Controversy—theological or canonistic—determined not only the pattern of their defense of the Franciscan doctrine of poverty but also the development of their polemics.The relationship between theology and canon law had been a perennial problem ever since the latter had grown into an independent discipline. Scholastic theologians in the thirteenth century were critical of canon law studies. Bonaventure, for example, affirmed theology’s superiority over canon law: he wrote that theology questioned propter quid, whereas canon law enquired into [End Page 418] quia. Bonaventure, following Aristotle, asserted that there are higher and lower sciences, and what for the higher science, theology, is the conclusion of its enquiry is for the lower science, canon law, its starting point. 4 Thomas Aquinas considered that the intrusion of the decretalists into theological matters was disagreeable and ridiculous, 5 as did Roger Bacon. 6 These theologians’ comments testify to the antagonism between theologians and canonists in the thirteenth century. Lawyers, too, were fully aware of this situation, as seen... (shrink)

The present article deals with the not very common opinion among medieval philosophers according to which the identity principle is the true first principle, undermining the primacy of the principle of non-contradiction. Following a refutation of this position in the logical work of the Franciscan Geraldus Odonis, we intend to investigate its target as well as other cases of the same dispute in 14th century authors: Antoine Andre, John of Buridan, John of Baconthorpe and Nicolas of Autrecourt. (...) We defend that Odonis presents a successful response to this position. (shrink)

In his recent book Against Liberalism, philosopher John Kekes argued that liberalism as a political system is doomed to failure by its internal inconsistencies. In this companion volume, he makes a compelling case for conservatism as the best alternative. His is the first systematic description and defense of the basic assumptions underlying conservative thought. Conservatism, Kekes maintains, is concerned with the political arrangements that enable members of a society to live good lives. These political arrangements are based on skepticism (...) about ideologies, pluralism about values, traditionalism about institutions, and pessimism about human perfectibility. The political morality of conservatism requires the protection of universal conditions of all good lives, social conditions that vary with societies, and individual conditions that reflect differences in character and circumstance. Good lives, according to Kekes, depend equally on pursuing possibilities that these conditions establish and on setting limits to their violations. Attempts to make political arrangements reflect these basic tenets of conservatism are unavoidably imperfect. Kekes concludes, however, that they represent a better hope for the future than any other possibility. (shrink)

This paper criticizes the traditional philosophical account of the quantization of gauge theories and offers an alternative. On the received view, gauge theories resist quantization because they feature distinct mathematical representatives of the same physical state of affairs. This resistance is overcome by a sequence of ad hoc modifications, justified in part by reference to semiclassical electrodynamics. Among other things, these modifications introduce "ghosts": particles with unphysical properties which do not appear in asymptotic states and which are said to be (...) purely a notational convenience. I argue that this sequence of modifications is unjustified and inadequate, making it a poor basis for the interpretation of ghosts. I then argue that gauge theories can be quantized by the same method as any other theory. On this account, ghosts are not purely notation: they are coordinates on the classical configuration space of the theory—specifically, on its gauge structure. This interpretation does not fall prey to the standard philosophical arguments against the significance of ghosts, due to Weingard. Weingard’s argumentative strategy, properly applied, in fact tells in favor of ghosts’ physical significance. (shrink)

This Element is an exposition of second- and higher-order logic and type theory. It begins with a presentation of the syntax and semantics of classical second-order logic, pointing up the contrasts with first-order logic. This leads to a discussion of higher-order logic based on the concept of a type. The second Section contains an account of the origins and nature of type theory, and its relationship to set theory. Section 3 introduces Local Set Theory, an important form of type theory (...) based on intuitionistic logic. In Section 4 number of contemporary forms of type theory are described, all of which are based on the so-called 'doctrine of propositions as types'. We conclude with an Appendix in which the semantics for Local Set Theory - based on category theory - is outlined. (shrink)

Educational Research is commonly regarded as a rational pursuit aimed at the production of objective knowledge. Researchers are expected to avoid value bias by detaching themselves from the normative conceptions of education that shape practice in schools and classrooms, and by casting themselves in the role of the impartial spectator. It is assumed that, as a rational pursuit, educational research is not directly concerned with changing practice but simply with discovering facts about it.This paper claims that it is possible to (...) construct a view of educational research as a form of rational and disciplined inquiry that does not depend on any underpinning spectator theory of knowledge. Nor, the paper claims, does it imply any underpinning foundational principles of rational action and choice. Rather it implies a form of disciplined conversation in which reasons for action are scrutinised, critiqued and modified without resort to foundational principles of rationality. Drawing particularly on the work of John Dewey, Richard Rorty and Amartya Sen, the paper casts educational research as a practical science—a form of action research—that is underpinned by a democratic conception of rationality. In doing so, it contrasts educational research, shaped by a pragmatic theory of knowledge, with research on education that is shaped by a spectator theory. (shrink)

In Empiricism and the Philosophy of Mind Sellars introduces the image of the space of reasons, and delineates a non-traditional empiricism, uncontaminated by the Myth of the Given. Brandom takes Sellars’s drift to be against empiricism as such, against the very idea that something deserving to be called “experience” could be relevant to the acquisition of empirical knowledge in any way except merely causally. In this paper I attack Brandom’s idea that we anyway need a concession to externalism for non-inferential (...) knowledge and suggest that in the space of reasons Sellars’s, the experience play a more than merely causal role in a fully internalist epistemology of observation.

Several philosophers have recently challenged cognitivism, i.e., the view that moral judgments are beliefs, by arguing that moral judgments are evidence non-responsive in a way that beliefs are not. If you believe that P, but acquire (sufficiently strong) evidence against P, you will give up your belief that P. This does not seem true for moral judgments. Some subjects maintain their moral judgments despite believing that there is (sufficiently strong) evidence against the moral judgments. This suggests that there is a (...) mismatch between moral judgments and beliefs. This is an interesting argument. In particular, it forces the cognitivist to be more explicit about the nature of belief and the sense in which moral judgments are responsive to evidence. This paper has two aims. First, it aims to systematically examine different versions of the argument from evidence non-responsiveness. Second, it aims to outline a more nuanced understanding of the sense in which beliefs are evidence responsive that explains why the extant versions of the argument do not constitute a challenge to cognitivism.

Background: A growing literature has raised—skeptically—the question of whether cutting-edge scientific research can identify and address broader ethical and policy considerations in real time. In genomics, the question is: Can ELSI contribute to genomics in real time, or will it be relegated to its historical role of after-the-fact outsider critique? We address this question against the background of a genomic screening project where we participated as embedded, real-time ELSI researchers and observers, from its initial design through its conclusion.Methods: As part (...) of the ELSI study design, the project included an ongoing reflexive ethnography in which the authors studied the process of its design and implementation. The authors were true participant observers, serving as members of various task-oriented groups while recording meetings and other events for ongoing qualitative analysis. We also conducted and analyzed interviews of multiple participants at the conclusion of the project.Results: Our real-time ELSI initiative had a mixed record of successes and challenges. If we define success as ELSI researchers having had an opportunity to participate fully in the project and to make the ELSI perspective heard, then our assessment is largely positive. If, however, we define successes as instances where real-time ELSI contributions changed the direction of the genomic or public health aspects of the GeneScreen project or, after careful deliberation, confirmed the appropriateness of the status quo, then we can identify only a few examples. While we had a seat at the table, we were, for the most part, tolerated guests.Conclusions: We conclude that there are significant barriers to real-time ELSI influence. The difficulty does not reside in any intended exclusion of an ELSI perspective, but in factors endemic to genomic research, including knowledge disparities, epistemological biases, and the pressures of time and money.

Why does democracy—as a word and as an idea—loom so large in the political imagination, though it has so often been misused and misunderstood? Setting the People Free starts by tracing the roots of democracy from an improvised remedy for a local Greek difficulty 2,500 years ago, through its near extinction, to its rebirth amid the struggles of the French Revolution. Celebrated political theorist John Dunn then charts the slow but insistent metamorphosis of democracy over the next 150 years (...) and its apparently overwhelming triumph since 1945. He examines the differences and the extraordinary continuities that modern democratic states share with their Greek antecedents and explains why democracy evokes intellectual and moral scorn for some, and vital allegiance from others. Now with a new preface and conclusion that ground this landmark work firmly in the present, Setting the People Free is a unique and brilliant account of an extraordinary idea. (shrink)

This special issue grew out of a small conference The Known & the Unknown: Exploring Twelfth-Century Philosophy, which was funded by the Carlsberg Foundation, hosted by the Saxo Institute, and held at the University of Copenhagen in April 2018. Its central topic was the many, mostly unexplored, commentaries on Aristotle, Boethius, and Porphyry that constitute the key textual evidence for a fascinating phenomenon that, although it played a pivotal role in the philosophical revival of Western Europe, remains frustratingly underexplored to (...) this day: the logical schools of the twelfth century. The present introduction has two parts. In the first part, John Marenbon lays out the background to this special issue of Vivarium as a whole, explaining both what the philosophical project pursued by twelfth-century logicians was and how, and how far, the historical project of understanding it has progressed over the last two hundred years. In the second part, Heine Hansen briefly presents the issue and its contents. (shrink)

Hermann Weyl, one of the twentieth century's greatest mathematicians, was unusual in possessing acute literary and philosophical sensibilities—sensibilities to which he gave full expression in his writings. In this paper I use quotations from these writings to provide a sketch of Weyl's philosophical orientation, following which I attempt to elucidate his views on the mathematical continuum, bringing out the central role he assigned to intuition.

This essay criticizes John Norton's 2010 defense of the thesis that “all induction is local.” Norton's local inductions are bound, if cogent, to involve general principles, and the need to accredit these general principles threatens to lead to all the usual problems associated with the ‘problem of induction’. Norton, in fact, recognizes this threat, but his responses are inadequate. The right response involves not induction but a sophisticated version of hypothetico-deduction. Norton's secondary thesis—that if there is a general account (...) of cogent scientific reasoning, then it is certainly not the one supported by personalist Bayesians—is also criticized. (shrink)

An article by John Dillon ardues that the Platonism that Plotinus inherits – setting aside Ammonius Saccas, of whom we know all too little – is by the later second century distinctly dualist in tendency, and is able, especially in the case of Plutarch, to quote Plato to its purpose. Plato himself, though, as the author maintains, is, despite appearances to the contrary, what one might term a ‘modified monist’. That is to say, he fully recognizes the degree of (...) imperfection and evil in the world, and holds it to be ineradicable, but he does not in the last resort believe in a positive countervailing force to the Good or the One. What we have is simply a negative force, whether Indefinite Dyad, disorderly World-Soul, or Receptacle, which is an inevitable condition of their being a world at all, but which, as a side-effect of introducing diversity, generates various sorts of imperfection. It is this scenario that justifies his follower Hermodorus in declaring that Plato recognizes only a single first principle, and it to this sort of monism – if anything, in a more pronounced form – that Plotinus returns.

The increasingly pervasive practice of veiling among Muslim women has stimulated a great deal of scholarly investigation and debate. This study brings empirical evidence to bear on current debates about the meaning of the veil in Islam. This article first examines the conflicting meanings of the veil among Muslim religious elites and Islamic feminists. Although the dominant gender discourse among Muslim elites strongly favors this cultural practice, an antiveiling discourse promulgated by Islamic feminists has gained ground within recent years. This (...) study then examines how these discursive disputes affect gender identity negotiation among veiled and unveiled Muslim women living in Austin, Texas. Interviews with these women highlight how their gender identities reproduce and reformulate existing Muslim gender discourses. Special attention is paid to the subjective disparities and points of congruence between both groups of respondents. This study concludes by suggesting avenues for future research on the intersection of gender, religion, and cultural difference. (shrink)

Clear focus on its application of formal logic to ordinary English is the most distinctive feature of this textbook for the introductory course in deductive logic. Great care is taken with the appropriate translation into logical languages of ordinary English sentences. Evaluation of these translations promotes a more effective use of ordinary language. The Principles of Deductive Logic presents symbolic logic in a fuller and more leisurely fashion than other introductory textbooks. Early chapters cover informal material, including definition and informal (...) fallacies. The remainder of the text is devoted to the treatment of four distinct artificial languages. The Categorical language is the language of syllogistic logic. The Extended Categorical language enriches this first language with the symbolic connectives for conjunction and negation. The Propositional Connective language and the First-Order language are the two basic languages of modern logic. Each language is accompanied by a deductive system, and is used as an instrument for exploring ordinary language, including ordinary arguments The book contains a large number of exercises whose answers are supplied in the back of the book, and many more that can be assigned as homework. A solution’s manual is available to instructors upon their request. The request must be written on college or university letterhead. (shrink)
