In this essay I argue that Albert would reject the need for a separate fourth mode of common personal supposition, and that his view of merely confused supposition has not been fully explicated by modern scholars. I first examine the various examples of conjunct descent given by modern scholars from his Perutilis logica , and show that Albert clearly adopts it in resolving the sophistic examples involved. Second, I explicate the view of merely confused supposition that Albert defends in his (...) Sophismata , and then attempt to answer the question: which view of merely confused supposition was his final view, the view articulated in the Perutilis logica or the view in the Sophismata ? I conclude that based upon his Sophismata view of merely confused supposition, Albert came to realize the logical strength his revised theory of personal supposition afforded, and consequently, that he is one of the earliest 14th-century logicians to adopt conjunct terminal descent to resolve various sophisms, a move which gave his theory of personal supposition a logical symmetry having two sorts of propositional descents to singulars, and two sorts of terminal descents to singulars.

I argue in the essay that the fourteenth-century logicians William Heytesbury and Albert of Saxony developed an argument I call the Socrates-Minus Argument. Their analysis and rejection of it indicates a direction towards a pragmatic resolution to the contemporary Descartes-Minus Argument. Their resolution is similar to the view adopted today by Peter van Inwagen, namely, that “arbitrary undetached parts of physical objects,” like 'all of Socrates except his finger' simply do not exist. I conclude the fourteenth-century approach does not run (...) afoul of Leibniz's law of the Indiscernibility of Identicals, but utilizes a form of Leibniz's Identity of Indiscernibles that, when combined with a weak “anthropic principle,” yield a pragmatic resolution to the Descartes-Minus Argument.

The essay develops two major arguments. First, if John Buridan's 'first argument' for the reintroduction of natural supposition is only that the "eternal truth" of a scientific proposition is preserved because subject terms in scientific propositions supposit for all the term's past, present, and future significata indifferently; then Albert of Saxony thinks it is simply ineffective. Only the 'second argument', i.e. the argument for the existence of an 'atemporal copula', adequately performs this task; but is rejected by Albert. Second, later (...) fourteenth-century criticisms of Buridan's natural supposition, given in certain Notabilia from the anonymous author in, Paris, BnF, lat. 14.716, ff. 40va-41rb, are nothing but an interpolated hodge-podge of criticisms given earlier in the century against various views of Buridan's by Albert of Saxony. It is this fact that makes Albert the real source of late fourteenth-century criticisms of Buridan's view of natural supposition. (shrink)

All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

Albert of Saxony was one of the great logicians of the Middle Ages, on a par with William Ockham and John Buridan. The Twenty-Five Disputed Questions on Logic treat of central issues in logic, both then and now, such as the nature of meaning, of universals, of truth, and of tense and modality; and the quality and quantity of propositions, the role of negation, and the relations of contradiction and equivalence between them. Dr. Fitzgerald has studied Albert's work extensively, and (...) previously edited the Twenty-Five Disputed Questions from the original manuscripts. This translation makes available for the first time in English this careful and exemplary examination of logical notions by an outstanding medieval thinker.-Stephen Read, University of St. Andrews.

The essay first makes some observations on the general interrelationship between the logical writings of Albert and Buridan. Second, it gives an account of a ‘semantic logical model’ for analyzing complex subject terms in some basic categorical propositions which is defended by Albert of Saxony, and briefly recounts Buridan's criticisms of that model. Finally, the essay maintains that the Albertian model is typically compatible with, and a further development of, what is called by a late-fourteenth century anonymous scholar ‘the English-Rule’ (...) but the ‘determinable/determinate’ grammatical model defended by Buridan is not.

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 23 (2003) 147-148 [Access article in PDF] Buddhists and Christians: Praying for Peace in the World Archbishop Michael L. Fitzgerald Pontifical Council for Interreligious Dialogue Dear Buddhist Friends:As the new president of the Pontifical Council for Interreligious Dialogue, the office of His Holiness the Pope for relations with people of different religious traditions, I wish to greet you and send this congratulatory message on the occasion of (...) the feast of Vesakh. This gesture of friendship, initiated in 1995 by my predecessor Cardinal Francis Arinze, has almost become a tradition. I wish to continue this good tradition and express my hearty congratulations to each and every one of you.In this message, I would like to invite you, my dear Buddhist friends, to join in prayer for the cause of peace in the world. Observing the current international situation, we cannot but be aware of the acuteness of the question of peace in our world. Since the beginning of this new millennium, marked by the dramatic events of September 11, 2001, we witness every day fresh scenes of bloodshed, violence, confrontation, and crisis in almost all parts of the world. In the midst of this grave situation, we cannot lead our lives without committing ourselves to advancing the cause of peace in the world.We Christians and Buddhists are convinced that the origin of all conflict is ultimately located in human hearts characterized by selfish desire, specifically by desire for power, domination, and wealth, often at the expense of others. It is also our common conviction that peace must inhabit people's hearts before it can become a social reality. For us, therefore, the most fundamental and efficient way to advance peace is to do our best to see that the deep-rooted selfishness of human hearts is overcome, so that people may be transformed into true artisans of peace.Pope John Paul II has proclaimed the year from October 2002 to October 2003 the Year of the Rosary of the Virgin Mary. He has earnestly encouraged the frequent recitation of the Rosary in order to pray for peace in the world. His wish to revive the practice of the Rosary is closely connected with the present historical circumstances, which need more than ever-constant supplication for the great gift of peace.My Buddhist friends, is it not a wonderful coincidence that you also have a lengthy tradition of using the Mala for prayer? The Rosary for Catholics and the [End Page 147] Mala for Buddhists are simple yet profound and meaningful prayer, despite essential differences in their form and content, based on our distinct doctrines and practices. For Catholics, the Rosary represents a most effective means of fostering contemplation of Jesus Christ. For Buddhists, the Mala is used to overcome the 108 Sinful Desires in order to reach the state of Nirvana. By virtue of their meditative character, these two prayers have in common a calming effect on those who pray them; they lead them to experience and to work for peace, and they produce fruits of love. For Catholics, the repetition and meditation of the holy names of the Persons of the Blessed Trinity and the Virgin Mary in the recitation of the Rosary makes us more willing to assimilate their love and compassion for others, especially for the poor and afflicted. In your Buddhist tradition, praying the Mala helps one to become a peacemaker.Dear Buddhist friends, these are the thoughts I wish to share with you this year. I am convinced that by persevering in prayer we will contribute to advancing peace in the world both now and in the future. May this peace be with you and your families on the feast of Vesakh and at all times.Archbishop Michael L. Fitzgerald, President © by Michael L. Fitzgerald. Reprinted by permission.... (shrink)

In the target article, Crespi & Badcock (C&B) propose a novel hypothesis based on observations that a large set of phenotypic traits exhibit diametrically opposite phenotypes in autism-spectrum versus psychotic-spectrum conditions.

The question can be put whether Nostra Aetate is addressing dialogue between religions,as its title would suggest, or encounter among the followers of different religions. Attention is paid first to the way the Council, in its other documents, speaks of religions. When the text of Nostra Aetate is examined, it is seen that its approach to religions is by no means exhaustive. Only a few religions are mentioned, and only positive aspects of them referred to. As regards dialogue or encounter, (...) it is shown that this really takes place between individual followers of religions, but abstraction cannot be made of the religious systems to which they belong.

In the essay I first argue that Albert ofSaxony's defense of perceptual ``directrealism'' is in fact a forerunner of contemporaryforms of ``process reliabilist''epistemologies. Second, I argue that Albert's defenseof perceptual direct realism has aninteresting consequence for his philosophy oflanguage. His semantic notion of `naturalsignification' does not require any semanticintermediary entity called a `concept' or`description', to function as the directsignificatum of written or spoken termsfor them to designate perceptual objects. AlthoughAlbert is inspired by Ockham's mentalact theory, I conclude that Albert seemsto (...) be striking out in a very new direction. (shrink)

The essay casts doubt upon the view that Albert was criticizing or was dependent upon Thomas Manlevelt's logico-philosophical views, and counter argues that it is in fact Manlevelt who knows and cites Albert's views in his recently edited Porphyrian Questions, rather than vice versa. The argument for this conclusion proceeds in two stages. First, it is argued that the brief comment Albert makes about ‘conjunct descent’ in treating the definition of merely confused supposition his Perutilis Logica does not conclusively show (...) that Albert is criticizing the logico-philosophical view of Thomas Manlevelt, as the notion of ‘conjunct descent’ is already present in the work of Heytesbury. Hence, Albert may have been referring to him, since the unique contribution of Thomas Manlevelt to the definition of merely confused personal supposition appears completely unknown to Albert. Second, it is argued that the views in the Porphyrian Questions on the nature of the continuum, quantity, and disposi.. (shrink)

The questions of violence, justice and judgment define one of the most resonant and constant concerns of contemporary thought. In part, this is only a reflection of what are often called the ‘realities on the ground’ . In the few years of this century the logic of violence, and even its aestheticisation – whether as terror or as ‘shock and awe,’ or in the citizen’s daily vocation to be ‘alert but not alarmed’ – have become the familiar data of current (...) experience. They are a kind of weather, felt through the colour-coded threat scale of the Homeland Security Advisory System, or in the casual references to the ‘current climate.’ In view of these realities, and of an acclimatisation to them that informs general popular support for extensions of executive power and legislative activity, the urgency of the turn or return to questions of force and law is to be expected. In the fabric of recent debate, they are seams at which confrontations are staged and positions defined; but also, where the thought that remains closest to the ‘realities on the ground’ is forced into juxtaposition with the mythological and theological schemes that violence, justice and judgment inevitably conjure. Thus, contributors to this issue of Colloquy were invited to consider whether it was possible to account for a difference between violence, terror and revolution, without simplification or banalisation of the relationship between law and force. On the one hand, the editors envisaged that this question would be a provocation to reexamine contemporary representations of sovereignty, jurisdiction and the ‘state of exception,’ in a global context dominated by issues of security and the justification of extra-legal and extra-judicial force – occupation, detention, torture. On the other hand, the reference to the mythological and the theological was inevitable, inasmuch as contributors were invited to organise their reflections around two of the most significant interventions in twentieth-century jurisprudence and political theory, Walter Benjamin’s “Critique of Violence” and Jacques Derrida’s “Force of Law.” For as is well-known, Benjamin and Derrida pursue their distinctive lines of questioning in the direction of a ‘divine violence’ or of a ‘mystical foundation of authority.’ The reception of the two texts suggests that these concepts remain, for many, difficult to the point of being indigestible; at least in the ‘current climate.’.

This book will be of interest to advanced students in philosophy, historians of logic and medieval philosophy, as well as logicians who wish to understand the significant contribution that Robert Kilwardby's thirteenth-century commentary on Aristotle's Prior Analytics made to those fields. Paul Thom's analysis treats Kilwardby's views on propositions, syllogisms, reduction, necessity, and contingency with depth and finesse, revealing what he takes to be the Aristotelian ontology underlying them. Helpful summaries remind the reader of the important formal and ontological results (...) of each chapter. The book is a genuine logical treat, despite a misleading typo of '' for '' at page 108, l.26, and the fact that most readers will need a good, strong magnifying glass for some of Brill's printed type and superscripts. I found only a couple of drawbacks. (shrink)
