We estimate that 208,000 deep brain stimulation (DBS) devices have been implanted to address neurological and neuropsychiatric disorders worldwide. DBS Think Tank presenters pooled data and determined that DBS expanded in its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. The DBS Think Tank was founded in 2012 providing a space where clinicians, engineers, researchers from industry and academia discuss current and emerging DBS technologies and logistical and ethical issues facing the field. (...) The emphasis is on cutting edge research and collaboration aimed to advance the DBS field. The Eighth Annual DBS Think Tank was held virtually on September 1 and 2, 2020 (Zoom Video Communications) due to restrictions related to the COVID-19 pandemic. The meeting focused on advances in: (1) optogenetics as a tool for comprehending neurobiology of diseases and on optogenetically-inspired DBS, (2) cutting edge of emerging DBS technologies, (3) ethical issues affecting DBS research and access to care, (4) neuromodulatory approaches for depression, (5) advancing novel hardware, software and imaging methodologies, (6) use of neurophysiological signals in adaptive neurostimulation, and (7) use of more advanced technologies to improve DBS clinical outcomes. There were 178 attendees who participated in a DBS Think Tank survey, which revealed the expansion of DBS into several indications such as obesity, post-traumatic stress disorder, addiction and Alzheimer’s disease. This proceedings summarizes the advances discussed at the Eighth Annual DBS Think Tank. (shrink)

Literary scholars are generally suspicious of the concept of universals: there are presently no candidates for literary universals that a high proportion of literary scholars would accept as valid. This paper reports results from a content analysis of patterns of characterization in folktales from 48 culture areas, aimed at identifying patterns of characterization that apply across regions of the world and levels of cultural complexity. The search for these patterns was guided by evolutionary theory and the findings are consistent with (...) previous research on patterns of altruism, sex differences in mate preferences, sex differences in reproductive strategy, and differing emphases on male and female physical attractiveness. World literature, especially originally oral literature, represents a vast and neglected repository of information that researchers can use to more precisely map the contours of human nature.

Import-Export says that a conditional 'If p, if q, r' is always equivalent to the conditional 'If p and q, r'. I argue that Import-Export does not sit well with a classical approach to conjunction: given some plausible and widely accepted principles about conditionals, Import-Export together with classical conjunction leads to absurd consequences. My main goal is to draw out these surprising connections. In concluding I argue that the right response is to reject Import-Export and adopt instead a limited version (...) which better fits natural language data; accounts for all the intuitions that motivate Import-Export in the first place; and fits better with a classical conjunction.

In lieu of an abstract, here is a brief excerpt of the content:Ius Gentium as Publicly Articulated Moral ScienceMatthew K. MinerdAmong the various types of law discussed in St. Thomas's theological "treatise on law"—questions 90–108 of Summa theologia [ST] I-II—the classification known as the "law of nations" (ius gentium) holds an ambiguous epistemological position. Marking a kind of halfway point between the natural law and civil law, it seems to straddle both domains. In fact, in a particularly important text dedicated (...) to this topic in the ST (I-II, q. 95, a. 4), Aquinas classes the ius gentium as being closely connected to the natural law, though in a way that is somewhat derivative, not as immediately flowing from human nature (especially in its animality) as does the natural law, but also not as marked by human contingency as is human civil law.As was recently discussed in a well-documented and insightful article by Barrett H. Turner in The Thomist, there have historically been two main lines of Thomist interpretation concerning the exact character of the "law of nations." Very broadly stated, what he refers to as the "Salamancan" line, indebted to Francisco de Vitoria, "interprets Thomas's doctrine of the ius gentium as a body of universal positive institutions (that is, specifications, determinationes) added to the natural law by agreement of the human race."1 [End Page 1043] This position, which would be common for several centuries among members of the Thomist school, would locate the law of nations essentially in the domain of nearly universally adopted customs and institutions, not strictly deduced from the natural law, but rather grounded on "the quasi-political authority of the entire human race, which promulgates the ius gentium by customs whose utility for attaining the ends of the natural law under a certain set of social conditions is easily recognized by rational creatures."2Turner calls the other line of thought "Maritain's Neo-Thomist Line,"3 an outlook that would be shared with various nuances by thinkers like Jean-Marie Aubert, Yves Simon, Marie-Michel Labourdette, John Finnis, and others. Setting aside my qualms about his appellation "neo-Thomist," which does more to obscure than to illumine (for it covers a host of Thomistic figures who have significantly different views on what constitutes "Thomism"), Turner does fairly lay out the major lines of Jacques Maritain's position, which is most directly articulated in Man and the State and La loi naturelle ou loi non-écrite.4 Basing himself on his particular view of knowledge of the natural law through connaturality,5 Maritain contrasted this sort of moral cognition with that which develops in the line of conceptual articulation, thus having a different "gnoseological" character from our knowledge of the natural law, while nonetheless still sharing the same "ontological" foundation. Such conceptually articulated law would be the ius gentium.Rather than add my voice to the dialectic of the various thinkers arrayed by Turner into the two aforementioned camps, I would like to propose a slightly different approach to the "moral epistemology of the law of nations," though one that I believe lies in line with the best aspects of Maritain's approach. Continuing a series of reflections that I have undertaken [End Page 1044] concerning moral epistemology during the past few years,6 I propose that it is most helpful to consider the "law of nations" as being a form of reasoning pertaining to what Scholastic vocabulary would refer to as "moral science,"7 namely discursive philosophical reasoning concerning the essences, properties, effects, and various other essential relationships that belong to a human acts, morally considered (the principal subject of moral philosophy), along with other subjects that are studied in relation to this principal subject (e.g., the principles of human acts, most particularly, the structure of human acts and the moral virtues). Moral science is the activity of reasoning that can be undertaken by knowing agents living together in community, seeking to discursively articulate and explain the moral truth that forms the essential basis for the contingent determinations that will then be codified in particular civil laws, the latter of which are not concerned with questions like "what are the ultimate foundations for property...

In this paper, the author spells out St. Bonaventure's magisterial teaching on the possibility of an eternal world, found in his 'Commentaria in II Sententiarum', d. 1, p. 1, a. 1, q. 2. The entirety of this 'quaestio' is treated at length in order to delineate its structure and indicate its reliance on both theological and philosophical premises. Hence, the twofold dependency of St. Bonaventure's position on Scripture and on arguments against an actual infinity is made clear. The author concludes (...) with a Thomistic response to the Seraphic Doctor's position, based solely on the Angelic Doctor's late treatise 'De aeternitate mundi', in which St. Thomas endeavors to place the eternal world question on purely philosophical grounds and also doubts the plausibility of arguments against the possiblity of an actual infinity.

One interpretation of the conditional If P then Q is as saying that the probability of Q given P is high. This is an interpretation suggested by Adams (1966) and pursued more recently by Edgington (1995). Of course, this probabilistic conditional is nonmonotonic, that is, if the probability of Q given P is high, and R implies P, it need not follow that the probability of Q given R is high. If we were confident of concluding Q from the fact (...) that we knew P, and we have stronger information R, we can no longer be confident of Q. We show nonetheless that usually we would still be justified in concluding Q from R. In other words, probabilistic conditionals are mostly monotonic. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 10.2 (2003) 161-167 [Access article in PDF] Social, Cognitive, and Neural Constraints on Subjectivity and Agency:Implications for Dissociative Identity Disorder Peter Q. Deeley In this commentary, I consider Matthew's argument after making some general observations about dissociative identity disorder (DID). In contrast to Matthew's statement that "cases of DID, although not science fiction, are extraordinary" (p. 148), I believe that there are natural (...) analogs of the disorder that, when considered, make it seem less puzzling and exotic. After discussing these examples, I examine the relations between social, cognitive, and neural processes supporting subjectivity and agency, to identify sources of personal identity in cases of DID that can be used as a basis for assessing Matthew's points against Behnke and Sinnott-Armstrong. I am not proposing a comprehensive theory, but rather identifying what I believe are components of such a theory. I then outline an approach to determining criminal responsibility in DID, drawing on analogies with other psychiatric disorders. Dissociative Identity Disorder DID is a disorder described in DSM-IV, which "is characterised by the presence of two or more distinct identities or personality states that recurrently take control of the individual's behaviour accompanied by an inability to recall important personal information that is too extensive to be explained by ordinary forgetfulness" (American Psychiatric Association, p. 519). Recognizing Personal Identity How is personal identity recognized in normal cognition? If we take personhood to involve recognition of continuity of social, psychological, and physical identity for a given individual, then such judgments are routinely made rapidly and automatically as an aspect of what has come to be termed social cognition (Adolphs 2003). There is likely to be considerable redundancy in [End Page 161] the types of information used to make judgments about whether a person is the same as one who was previously encountered, or perhaps heard about—for example, facial features, movement patterns, speech prosody, dress, speech content, gender, ethnicity, social role, among other features, all provide information about individual identity, and hence personhood. When uncertainty exists, it is likely to reflect a loss or alteration of cues that would ordinarily be used in a rapid, automatic, unexamined way (Adolphs 2003). In such extreme cases (for example, severe mental illness or disfigurement), the problem of identification becomes the subject of explicit reasoning (and hence of potential disagreement, because we then engage in post hoc rationalizations to establish criteria for determining personhood, whereas normally we rely on essentially automatic, implicit abilities that work in most circumstances, some of which make little use of linguistic representations and formal reasoning—for example, individual facial identity recognition, which may occur as quickly as 170 ms after stimulus onset [Adolphs 2003]). Nevertheless, examining our judgments and intuitions in cases that force us to explicitly consider whether personal identity is preserved may provide analogies and clues for how we should proceed with DID. Let us consider, then, some natural analogs of DID. Natural Analogs of DID Method Acting I suggest that method acting is an analog of DID (Manderino 1985). Method acting refers to an approach to acting training and performance in which emphasis is placed on intensely imagining and identifying with the mental life of the character being portrayed. Training courses and manuals list many techniques and practices that can be used to facilitate absorption in a role, drawing on different kinds of memory—for example, experiential memories, memories of others, general knowledge (semantic memory), and memories of sensations and feelings, to creative a vivid sense of the subjective experience and actions of the character. Manderino, a method acting teacher, comments: "it is important to investigate the way in which your own mental makeup can improperly influence a character. Insecurities, self-consciousness, shyness or self-doubts can maintain a strong hold, and permitting any of these feelings to enter a performance is to remain the actor and not enter into the mental life of the character. For some, acting allows personal problems to be left behind, and they are thankful for the complete escape that... (shrink)

Conditional information can be equally asserted in the forms if p, then q (e.g., ?if I am ill, I will miss work tomorrow?) and q, if p (e.g., ?I will miss work tomorrow, if I am ill?). While this type of clause order manipulation has previously been found to have no influence on the ultimate conclusions participants draw from conditional rules, we used self-paced reading to examine how it affects the real time incremental processing of everyday conditional statements. Experiment 1 (...) revealed that clause order interacts with presuppositional congruency as readers hypothetically represent counterfactual statements. When if p, then q counterfactuals contained a presupposition that was incongruent with prior context, these statements took longer to read than when the presupposition was congruent, but for q, if p conditionals there was no such congruency effect. Experiment 2 revealed that reading times were influenced by the subjective probability of an indicative conditional regardless of clause order, with a penalty observed for low-probability statements relative to high-probability statements in both conditional clause orders. These data reveal a dissociation whereby clause order mediates the effect of suppositional congruency on reading times, but does not mediate the effect of subjective probability. (shrink)

This essay examines the role that circumstances play in determining the morality of moral acts as presented in ST I-II, q. 18 and argues that q. 18 uses two different sets of principles that are left unreconciled in the text. The paper argues that consequently the text is not coherent but is radically divided; specifically, q. 18 holds both that a circumstance—by virtue of being a true circumstance and accident of the act—can make a good act evil but also that (...) whenever a circumstance renders a good act evil it must cease to be a circumstance and an accident. This paper then shows that in De Malo, q. 2 Aquinas provides a distinct and heretofore unappreciated account of circumstances and that he explicitly used the unique features of this account to reconcile the propositions that were left unreconciled in q. 18.

A quasi-order Q induces two natural quasi-orders on $${\mathcal{P}(Q)}$$, but if Q is a well-quasi-order, then these quasi-orders need not necessarily be well-quasi-orders. Nevertheless, Goubault-Larrecq (Proceedings of the 22nd Annual IEEE Symposium 4 on Logic in Computer Science (LICS’07), pp. 453–462, 2007) showed that moving from a well-quasi-order Q to the quasi-orders on $${\mathcal{P}(Q)}$$ preserves well-quasi-orderedness in a topological sense. Specifically, Goubault-Larrecq proved that the upper topologies of the induced quasi-orders on $${\mathcal{P}(Q)}$$ are Noetherian, which means that they contain no (...) infinite strictly descending sequences of closed sets. We analyze various theorems of the form “if Q is a well-quasi-order then a certain topology on (a subset of) $${\mathcal{P}(Q)}$$ is Noetherian” in the style of reverse mathematics, proving that these theorems are equivalent to ACA 0 over RCA 0. To state these theorems in RCA 0 we introduce a new framework for dealing with second-countable topological spaces. (shrink)

Sustainable and ethical leadership in the financial industry expand in importance since the financial crisis of 2007–2009. This research examined the level of sustainable and ethical leadership of leaders in mortgage loan originator (MLO) organizations, as perceived by loan originators.

The survey results yielded (...) high levels of both ethical and sustainable leadership. Employees also felt their leadership was encouraging ethical and sustainable behavior. However, correlations between the PLIS and SLQ did not prove to be dependent or closely correlated. (shrink)

Bayesians take “definite” or “single-case” probabilities to be basic. Definite probabilities attach to closed formulas or propositions. We write them here using small caps: PROB(P) and PROB(P/Q). Most objective probability theories begin instead with “indefinite” or “general” probabilities (sometimes called “statistical probabilities”). Indefinite probabilities attach to open formulas or propositions. We write indefinite probabilities using lower case “prob” and free variables: prob(Bx/Ax). The indefinite probability of an A being a B is not about any particular A, but rather about the (...) property of being an A. In this respect, its logical form is the same as that of relative frequencies. For instance, we might talk about the probability of a human baby being female. That probability is about human babies in general — not about individuals. If we examine a baby and determine conclusively that she is female, then the definite probability of her being female is 1, but that does not alter the indefinite probability of human babies in general being female. Most objective approaches to probability tie probabilities to relative frequencies in some way, and the resulting probabilities have the same logical form as the relative frequencies. That is, they are indefinite probabilities. The simplest theories identify indefinite probabilities with relative frequencies.3 It is often objected that such “finite frequency theories” are inadequate because our probability judgments often diverge from relative frequencies. For example, we can talk about a coin being fair (and so the indefinite probability of a flip landing heads is 0.5) even when it is flipped only once and then destroyed (in which case the relative frequency is either 1 or 0). For understanding such indefinite probabilities, it has been suggested that we need a notion of probability that talks about possible instances of properties as well as actual instances.. (shrink)

The conference was organized and sponsored by the HYELE Institute for Comparative Studies, Parmenides Publishing, and Starcom AG, with endorsements from the International Plato Society, and the Dean of the School of Arts and Sciences, University of Pennsylvania. While Kahn's work reaches far beyond the Presocratics and (...) Plato, it is in these subject areas that the distinction of his scholarship has come to be regarded as virtually unrivaled. The articles contributed to this volume are by some of the most renowned scholars working on these topics today, their breadth and depth bearing witness to his profound impact and influence on the discipline of Ancient Greek Philosophy._ Charles Kahn taught Classics and Philosophy at Columbia University from 1957 to 1965, and has since been teaching in the Philosophy Department of the University of Pennsylvania. He spent a year as Visiting Professor at the American School of Classical Studies in Athens, and had additional Visiting Fellowships at Balliol College, Oxford and Clare Hall, Cambridge, and a term as Visiting Professor at Harvard. He is the recipient of several prestigious research grants, from the American Council of Learned Societies, the National Endowment for the Humanities, and the Guggenheim Foundation. In 2000 he was elected Fellow of the National Academy of Arts and Sciences.

Contrary to Vaesen's argument that humans are unique with respect to nine cognitive capacities essential for tool use, we suggest that although such cognitive processes contribute to variation in tool use, it does not follow that these capacities arenecessaryfor tool use, nor that tool use shaped cognition per se, given the available data in cognitive neuroscience and behavioral biology.

Aristotle founds his modal syllogistic, like his plain syllogistic, on a small set of ?perfect? or obviously valid sylligisms. The rest he reduces to those, usually by means of modal conversion principles. These principles are open to more than one reading, however, and they are in fact invalid on one traditional reading (de re), valid on the other (de dicto). It is argued here that this way of framing the contrast is not Aristotelian, and that an interpretation involving modal copulae (...) allows us to see how these principles, and the modal system as a whole, are to be understood in light of close and precise connections to Aristotle's essentialist metaphysics.

This study considers the verisimilitude of the harvest saying in Matthew 9.37–38 and Luke (Q) 10.2, specifically the opening statement that the harvest is plentiful but the workers few. By ‘verisimilitude’ is meant the tradition’s tendency to be viewed as realistic in its original socio-historical context. In other words, would the first listeners have nodded their heads in agreement at the claim that the harvest is plentiful but the workers few? The focus here is not on the logion’s possible (...) metaphorical application, but on the literal saying, which involves ancient agriculture. To address the verisimilitude question, the study will consider some individual features of the logion itself, as well as the socio-historical context of farming and harvesting in 1st-century Palestine and the Roman Empire. Contribution: This study attempts to determine the verisimilitude of the literal claim that the harvest is plentiful but the workers few. The author is not aware of any other study that attempts to answer this verisimilitude question about Matthew 9.37–38 and Luke (Q) 10.2. Answering this question is sure to contribute to the understanding and interpretation of the chosen logion in the future. (shrink)

MacIntyre argues that management embodies emotivism, and thus is inherently amoral and manipulative. His claim that management is necessarily Weberian is, at best, outdated, and the notion that management aims to be neutral and value free is incorrect. However, new forms of management, and in particular the increased emphasis on leadership which emerged after MacIntyre’s critique was published, tend to support his central charge. Indeed, charismatic and transformational forms of leadership seem to embody emotivism to a greater degree than do (...) more Weberian, bureaucratic forms of management; hence, MacIntyre’s central contention about our emotivistic culture seems to be well founded. Having criticised the details but defended the essence of MacIntyre’s critique of management, this paper sketches a MacIntyrean approach to management and leadership by highlighting the affinities between MacIntyre’s political philosophy and Greenleaf’s concept of servant leadership.

The first edition of The Scientific Background to Modern Philosophy took the dialogue of science and philosophy from Aristotle through to Newton.

This paper initiates analytic inquiry into the metaphysics of masculinity.

The notion that business organizations are akin to Aristotelian political communities has been a central feature of research into virtue ethics in business. In this article, I begin by outlining this “community thesis” and go on to argue that psychological research into the “just world fallacy” presents it with a significant challenge. The just world fallacy undermines our ability to implement an Aristotelian conception of justice, to each as he or she is due, and imperils the relational equality required for (...) shared participation in communities. In the final section, I offer a description of what Aristotelian community might look like within organizations, and some suggestions about how it may be possible to resist the challenge posed by the just world fallacy.

This article approaches the issue of Matthew’s theological context by examining Matthew’s use of Mark, including through redaction and supplementation, in Matthew 1–4. This is undertaken in two parts: Matthew 1–2, which is largely additional material, and Matthew 3–4, followed by a concluding assessment. Issues addressed or alluded to in these chapters frequently find resonance in the remainder of Matthew’s gospel and so give important clues about Matthew’s concerns and their relevance for understanding (...) its context. Such issues include the importance of messiahship; continuity with Israel, but also with John the Baptist and the Church; defence against slander; heightened christological claims; soteriology; Gentile mission; the status of Torah; and Jesus as judge to come. The article suggests a location within a Jewish religious context with a Jewish self-understanding, separate from the synagogue, but claiming to belong where its opponents would claim it did not; and a Christian tradition where the approach of ‘Q’ to Torah is upheld in contrast to Mark’s, while embracing and expanding Mark’s Christology and restoring the common understanding of Gentile mission as a post- Easter phenomenon.

A probability distribution is regular if it does not assign probability zero to any possible event. While some hold that probabilities should always be regular, three counter-arguments have been posed based on examples where, if regularity holds, then perfectly similar events must have different probabilities. Howson and Benci et al. have raised technical objections to these symmetry arguments, but we see here that their objections fail. Howson says that Williamson’s “isomorphic” events are not in fact isomorphic, but Howson is speaking (...) of set-theoretic representations of events in a probability model. While those sets are not isomorphic, Williamson’s physical events are, in the relevant sense. Benci et al. claim that all three arguments rest on a conflation of different models, but they do not. They are founded on the premise that similar events should have the same probability in the same model, or in one case, on the assumption that a single rotation-invariant distribution is possible. Having failed to refute the symmetry arguments on such technical grounds, one could deny their implicit premises, which is a heavy cost, or adopt varying degrees of instrumentalism or pluralism about regularity, but that would not serve the project of accurately modelling chances.

Christian realism is undergoing a renaissance in both American Christianity and around the world. Caught between globalist liberalism, on the one hand, and pragmatic realism on the other, Christians are in search of international ethics, a standard and tradition in foreign policy, that takes the two great books of life, the Christian Scriptures and the world we live in, seriously. This book is an extended, edited collection that mines the tradition of Christian realism in international relations and finds in it (...) voices and mentors urgently fresh for a new age.

What a concept does for us is a matter of what we can do with it, and what we do with concepts is deploy them in thought and language.

Recent research on the evolution of religion has focused on whether religion is an unselected by-product of evolutionary processes or if it is instead an adaptation by natural selection. Adaptive hypotheses for religion include direct fitness benefits from improved health and indirect fitness benefits mediated by costly signals and/or cultural group selection. Herein, I propose that religious denominations achieve indirect fitness gains for members through the use of ecologically arbitrary beliefs, rituals, and moral rules that function as recognition markers of (...) cultural inheritance analogous to kin and species recognition of genetic inheritance in biology. This recognition signal hypotheses could act in concert with either costly signaling or cultural group selection to produce evolutionarily altruistic behaviors within denominations. Using a cultural phylogenetic analysis, I show that a large set of religious behaviors among extant Christian denominations supports the prediction of the recognition signal hypothesis that characters change more frequently near historical schisms. By incorporating demographic data into the model, I show that more-distinctive denominations, as measured through dissimilar characteristics, appear to be protected from intrusion by nonmembers in mixed-denomination households, and that they may be experiencing greater biological growth of their populations even in the present day.

In lieu of an abstract, here is a brief excerpt of the content:242 HISTORY OF PHILOSOPHY his political and religious predispositions prodded him to demonstrate that the roots of modern science were in the Christian Middle Ages. Sarton's particular foibles are best understood by referring them to his pacifist commitments and the moralistic assumption that the values of science are transferable to other human endeavors. Categories such as inductivism, conventionalism and Popperianism are of little help in gaining historical understanding. For (...) this, they are in fact Platonic ideals which have little heuristic value. I would venture that a truly historical historiography of science would aid us in spotting errors in the past and help us in the future. My guess is that a good analysis would reveal a major source of trouble to have stemmed from preconceived notions which the history of science was meant to illustrate. Surely some of them have been philosophical in character, and even Baconian or conventionalist. But until recent times, most of these preconceptions have stemmed from religious, nationalistic, or personal motivations, or from scientists who wanted support for a particular concept. I agree with Agassi only in the suggestion that a parti pris was at the root of our troubles. Why, then, substitute a Popperian preconception for a conventionalist one? Why not, on the contrary, combat their distorting influence and reduce their impact? This is in fact what has happened in recent times. As the history of science has fallen into the hands of a gradually organized profession, the blatant motivations --of any type--which colored past historical writings have slowly receded. By a constant and critical confrontation of opposing views among specialists, the purpose for examining the history of science has slowly been transformed. The older external motivations have given way to an interest in the subject for its own sake and a gradual transformation has been in the making for the last few decades. As happens in other human endeavors, professionalization has already raised the standards in the discipline and there is every reason to think it will continue to do so in the future. We need not really be as pessimistic as Agassi, nor embrace his particular salvation. ROGEa HAm~ University o] Cali]ornia, Berkeley A MEDIEVAL ANALYSIS OF INFINITY IN THE COURSEof arguing that time must have had a beginning, St. Bonaventure (1221-74) put forward a demonstration which in some ways seems to anticipate Cantor's definition of infinity.1 Bonaventure pointed out that, if the world were infinitely old, then there would have been an infinite number of annual revolutions of the sun around the ecliptic. But during each such period there occur (roughly) twelve revolutions of the moon, i.e. lunar months or lunations. Thus there would be one infinity which was twelve times another--which, says Bonaventure, is impossible. This attempted proof might be formulated as the following For other adumbrationsof this definition,see I. Thomas,"A TwelfthCentury Paradoxof the Infinite,"Journal o] Symbolic Logic, XXIII (1958), 133-134, and W. & M. Kneale, The Development of Logic (Oxford,1962),p. 440.

If there could be an infinite set of past lunations, then clearly it could be put in a one-to-one correspondence with a proper sub-set of itself--viz., with the set of past lunar months during which vernal equinoxes occurred. But this consequence is preposterous; no set could be so correlated with its own sub-set. Therefore the set of past lunar months cannot be infinite, and the world must have had a beginning. The passage, which is found in Bonaventure's commentary on the Sentences of Peter Lombard, reads as follows :2 Si mundus est aeternus, revolutiones solis in orbe suo sunt infmitae ; rursus, pro una revolutions solis necesse est fuisse duodecim ipsius lunae: ergo plus revoluta est luna quam sol; et sol infinities: ergo infinitorum ex ea parle, qua infinita sunt, est reperire excessum.

Shared agency is a distinctive kind of sociality that involves interdependent planning, practical reasoning, and action between participants. Philosophical reflection suggests that agents engage in this form of sociality when a special structure of interrelated psychological attitudes exists between them, a set of attitudes that constitutes a collective intention. I defend a new way to understand collective intention as a combination of individual conditional intentions. Revising an initial statement of the conditional intention account in response to several challenges leads to (...) a specification of the properties these intentions need to have in order to be genuine commitments.
