A well-known objection to divine simplicity holds that the doctrine is incompatible with God’s contingent knowledge. I set out the objection and reject two problematic solutions. I then argue that the objection is best answered by adopting an “extrinsic model of divine knowing” according to which God’s contingent knowledge, which varies across worlds, does not involve any intrinsic variation in God. Solutions along these lines have been suggested by others. This paper advances the discussion by developing and offering partial defenses (...) of three such models. (shrink)

Are all God’s activities identical to God? If not, which are identical to God and which not? Although it is seldom noticed, the texts of Aquinas (at least on the surface) suggest conflicting answers to these questions, giving rise to a diversity of opinion among interpreters of Aquinas. In this paper, we draw attention to this conflict and offer what we believe to be the strongest textual and speculative support for and against each of the main answers to these questions.

The privation account of moral evil holds that the badness of morally bad acts consists not in the positive act itself or in any positive feature of the act but rather in the act’s lack of conformity to the moral standard. Traditionally recognized for its theological usefulness, the account has been the target of at least five recent objections. In this paper I offer a positive philosophical argument for the account and then show that the objections fail.

According to prevailing opinion, if a creaturely act is caused by God, then it cannot be free in the libertarian sense. I argue to the contrary. I distinguish intrinsic and extrinsic models of divine causal agency. I then show that, given the extrinsic model, there is no reason one holding that our free acts are caused by God could not also hold a libertarian account of human freedom. It follows that a libertarian account of human freedom is consistent with God’s (...) being the source and cause of all being apart from himself, including the being of free human actions. (shrink)

Peter Furlong has recently raised an objection to my defense of Aquinas’s approach to explaining how God could cause all creaturely actions without causing sin. In this short paper, I argue that the objection fails.

Aquinas maintains that, although God created the universe, he could have created another or simply refrained from creating altogether. That Aquinas believesin divine free choice is uncontroversial. Yet doubts have been raised as to whether Thomas is entitled to this belief, given his claims concerning divine simplicity.According to simplicity, there is no potentiality in God, nor is there a distinction in God between God’s willing, His essence, and His necessary being. On the surface, it appears that these claims leave no (...) room for divine free choice. I argue that attempts by Aquinas and a pair of his contemporary defenders to reconcile God’s freedom with God’s simplicity fail to resolve the problem. Nevertheless, I maintain that Aquinas provides the key to a resolution in his claim that while creatures are really related to God, God is not really related to creatures. (shrink)

Aquinas teaches that human acts are caused by God. Assuming that such causation entails theological determinism, philosophers with libertarian intuitions tend either to read around Aquinas’s teaching on the relation of divine causality and human action, or to reject that teaching altogether. Unfortunately, the arguments most often used by Aquinas and his contemporary defenders to show that his teaching is compatible with human freedom fail to address thelibertarian’s main concerns. In part one of this essay, I consider these arguments and (...) show why they fail. In part two, I attempt to address the libertarian’s concerns more directly by arguing that Aquinas should not be thought of as a theological determinist. I will show that theological determinism presupposes acertain logic or explanatory scheme, which Aquinas’s understanding of God, and in particular of divine simplicity, will not accommodate. Hence, the kinds ofinferences needed to make theological determinism intelligible do not apply in Aquinas’s case. (shrink)

According to a classical teaching, God is not really related to creatures even by virtue of creating them. Some have objected that this teaching makes unintelligible the claim that God causally accounts for the universe, since God would be the same whether the universe existed or not. I defend the classical teaching, showing how the doctrine is implied by a popular cosmological argument, showing that the objection to it would also rule out libertarian agent causality, and showing that the objection (...) rests on an account of causality and sufficient reason that we have good reason to reject.

Peter Furlong has recently raised an objection to my defense of Aquinas’s approach to explaining how God could cause all creaturely actions without causing sin. In this short paper, I argue that the objection fails.

On a traditional account, God causes sinful acts and their properties, insofar as they are real, but God does not cause sin, since only the sinner causes the privations in virtue of which such acts are sinful. After explicating this privation solution, I defend it against two objections: (1) that God would cause the sinful act’s privation simply by causing the act and its positive features; and (2) that there is no principled way to deny that God causes the privation (...) yet still affirm that the sinner causes it. I close by considering a limitation of the privation solution. (shrink)

It is human nature to try to recognize patterns and to make sense of that which we observe. Unfortunately, our intuition is often wrong, and so there is a need to impose some objectivity on the methods by which observations are converted into knowledge. One definition of biostatistics could be precisely this, the rigorous and objective conversion of medical and/or biological observations into knowledge. Both consumers of biostatistical principles and biostatisticians themselves vary in the extent to which they recognize the (...) need to continue the improvement. Some may not recognize the need for (some or all of) the methods that have already been developed; others may accept these as they find them completely sufficient; still others recognize both the value and the shortcomings of these methods, and seek to develop even better methods to ensure that future medical conclusions are less subject to biases than current ones are.

1 Adaptationism is a research strategy that seeks to identify adaptations and the specific selective forces that drove their evolution in past environments. Since the mid-1970s, paleontologist Stephen J. Gould and geneticist Richard Lewontin have been critical of adaptationism, especially as applied toward understanding human behavior and cognition. Perhaps the most prominent criticism they made was that adaptationist explanations were analogous to Rudyard Kipling's Just So Stories. Since storytelling is an inherent part of science, the criticism refers to the acceptance (...) of stories without sufficient empirical evidence. In particular, Gould, Lewontin, and their colleagues argue that adaptationists often use inappropriate evidentiary standards for identifying adaptations and their functions, and that they often fail to consider alternative hypotheses to adaptation. Playing prominently in both of these criticisms are the concepts of constraint, spandrel, and exaptation. In this article we discuss the standards of evidence that could be used to identify adaptations and when and how they may be appropriately used. Moreover, building an empirical case that certain features of a trait are best explained by exaptation, spandrel, or constraint requires demonstrating that the trait's features cannot be better accounted for by adaptationist hypotheses. Thus, we argue that the testing of alternatives requires the consideration, testing, and systematic rejection of adaptationist hypotheses. Where possible, we illustrate our points with examples taken from human behavior and cognition. Key Words: adaptation; ADHD; brain allometry; constraint; epistemology; evolutionary psychology; exaptation; female orgasm ; optimization; special design; waist-hip ratio.

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.

In our target article, we discussed the standards of evidence that could be used to identify adaptations, and argued that building an empirical case that certain features of a trait are best explained by exaptation, spandrel, or constraint requires the consideration, testing, and rejection of adaptationist hypotheses. We are grateful to the 31 commentators for their thoughtful insights. They raised important issues, including the meaning of “exaptation”; whether Gould and Lewontin's critique of adaptationism was primarily epistemological or ontological; the necessity, (...) sufficiency, or utility of design evidence, phylogenetic analyses, homology, and molecular genetics in distinguishing exaptations from adaptations; whether adaptationists accept adaptationist hypotheses too quickly; and the real utility of adaptationism to human behavioral science. We organize our response along the major points of the target article, in some situations defending our original claims and in others modifying them. While debate on these issues will undoubtedly continue, we are cautiously optimistic that the main points of the target article (as modified by our response) will help move the debate in a positive direction.

Recent work has defended “Euclidean” theories of set size, in which Cantor’s Principle (two sets have equally many elements if and only if there is a one-to-one correspondence between them) is abandoned in favor of the Part-Whole Principle (if A is a proper subset of B then A is smaller than B). It has also been suggested that Gödel’s argument for the unique correctness of Cantor’s Principle is inadequate. Here we see from simple examples, not that Euclidean theories of set (...) size are wrong, but that they must be either very weak and narrow or largely arbitrary and misleading. (shrink)

Blair articulates a concept of argument that suggests, as he puts it, that argument is a normative concept (Blair, Informal Logic 24:137–151, 2004, p. 190). Put roughly, the idea is that a collection of propositions doesn’t constitute an argument unless some taken together constitute a reason for the remaining proposition and thereby support it enough to provide at least prima facie justification for it (Blair, in: Blair, Johnson, Hansen, Tindale (eds) Informal Logic at 25, Proceedings of the 25th anniversary conference, (...) Ontario Society for the Study of Argumentation, 2003, p.173). My primary task in this paper is to advance an understanding of the illative unit of argument and the reasons associated with it that provides an intuition pump for a normative concept of argument. My aim is to advance a positive consideration in favor of a normative concept of argument that motivates its further development. I take the normative concept of argument I defend here to be in the same ballpark as the one Blair characterizes. (shrink)

A good therapeutic relationship in mental health services is a predictor of positive clinical outcomes for people who seek help for distressing experiences, such as voice hearing and paranoia. One factor that may affect the quality of the therapeutic relationship and raises further ethical issues is the impact of the clinical encounter on users’ sense of self, and in particular on their sense of agency. In the paper, we discuss some of the reasons why the sense of epistemic agency may (...) be especially fragile in young people with unusual experiences and beliefs. We argue that it is important to identify and avoid behaviours that can undermine young people’s contributions as epistemic agents in the clinical encounter. (shrink)

At the same time that social justice concerns are on the rise on college campuses, empathy levels among US college students are falling. Social injustice resulting from organizational decisions and actions causes profound and unnecessary human suffering, and research to understand antecedents to these decisions and actions lacks attention. Empathy represents a potential tool and critical skill for organizational decision-makers, with empirical evidence linking empathy to moral recognition of ethical situations and greater breadth of understanding of stakeholder impact and improved (...) financial success. This study explores the potential relationship between empathy and social justice, using a multifaceted operationalization of social justice, which includes management actions and social sympathies. Results broadly support the positive empathy and social justice relationship and suggest higher education interventions to develop empathy in college business students. (shrink)

This book is a collection of edited interviews from The Free Will Show-a podcast that provides a beginner-friendly introduction to free will while also highlighting recent developments on the topic. The book includes original material as well, including an introduction to the interviews and an afterward with reflections on the podcast by the authors (who are cohosts of The Free Will Show). The book also includes a bibliography and suggestions for further reading after each interview and a glossary of terms (...) at the end of the book. The book will serve well either as a textbook or as an accessible entry-point to the free will debate, whether for an interested non-specialist or a philosopher who works in another area. The first half of this book introduces the main issues and arguments in philosophical debates about free will, including various apparent threats to free will (fatalism, foreknowledge, and determinism), the Consequence Argument, and the problem of luck, among others. The second half of this book introduces the main positions in the debate about free will and determinism, including several varieties of libertarianism and compatibilism, a version of free will skepticism, and some other positions that do not fit neatly into these categories.

There is no uniquely standard concept of an effectively decidable set of real numbers or real n-tuples. Here we consider three notions: decidability up to measure zero [M.W. Parker, Undecidability in Rn: Riddled basins, the KAM tori, and the stability of the solar system, Phil. Sci. 70(2) (2003) 359–382], which we abbreviate d.m.z.; recursive approximability [or r.a.; K.-I. Ko, Complexity Theory of Real Functions, Birkhäuser, Boston, 1991]; and decidability ignoring boundaries [d.i.b.; W.C. Myrvold, The decision problem for entanglement, in: R.S. (...) Cohen et al. (Eds.), Potentiality, Entanglement, and Passion-at-a-Distance: Quantum Mechanical Studies fo Abner Shimony, Vol. 2, Kluwer Academic Publishers, Great Britain, 1997, pp. 177–190]. Unlike some others in the literature, these notions apply not only to certain nice sets, but to general sets in Rn and other appropriate spaces. We consider some motivations for these concepts and the logical relations between them. It has been argued that d.m.z. is especially appropriate for physical applications, and on Rn with the standard measure, it is strictly stronger than r.a. [M.W. Parker, Undecidability in Rn: Riddled basins, the KAM tori, and the stability of the solar system, Phil. Sci. 70(2) (2003) 359–382]. Here we show that this is the only implication that holds among our three decidabilities in that setting. Under arbitrary measures, even this implication fails. Yet for intervals of non-zero length, and more generally, convex sets of non-zero measure, the three concepts are equivalent. (shrink)

This article stages a new encounter between rhetoric and the philosophy of Karl Marx. We argue that the configuration of two major tropes in Marx’s 1852 pamphlet The Eighteenth Brumaire of Louis Bonaparte renders explicit the operative but implicit logics of Marxian historical materialism. Our reading therefore makes available a novel and untimely dimension of Marx’s conceptual labor where we least expect to find it: in a text that has been largely, but not exclusively, understood as a history of counterrevolution (...) that was meant to intervene within its own context in particular ways. While we do not wish to lose sight of that context, our aim is to demonstrate that The Eighteenth Brumaire is suggestive of the.. (shrink)

We consider an approach to some philosophical problems that I call the Method of Conceptual Articulation: to recognize that a question may lack any determinate answer, and to re-engineer concepts so that the question acquires a definite answer in such a way as to serve the epistemic motivations behind the question. As a case study we examine “Galileo’s Paradox”, that the perfect square numbers seem to be at once as numerous as the whole numbers, by one-to-one correspondence, and yet less (...) numerous, being a proper subset. I argue that Cantor resolved this paradox by a method at least close to that proposed—not by discovering the true nature of cardinal number, but by articulating several useful and appealing extensions of number to the infinite. Galileo was right to suggest that the concept of relative size did not apply to the infinite, for the concept he possessed did not. Nor was Bolzano simply wrong to reject Hume’s Principle (that one-to-one correspondence implies equal number) in the infinitary case, in favor of Euclid’s Common Notion 5 (that the whole is greater than the part), for the concept of cardinal number (in the sense of “number of elements”) was not clearly defined for infinite collections. Order extension theorems now suggest that a theory of cardinality upholding Euclid’s principle instead of Hume’s is possible. Cantor’s refinements of number are not the only ones possible, and they appear to have been shaped by motivations and fruitfulness, for they evolved in discernible stages correlated with emerging applications and results. Galileo, Bolzano, and Cantor shared interests in the particulate analysis of the continuum and in physical applications. Cantor’s concepts proved fruitful for those pursuits. Finally, Gödel was mistaken to claim that Cantor’s concept of cardinality is forced on us; though Gödel gives an intuitively compelling argument, he ignores the fact that Euclid’s Common Notion is also intuitively compelling, and we are therefore forced to make a choice. The success of Cantor’s concept of cardinality lies not in its truth (for concepts are not true or false), nor its uniqueness (for it is not the only extension of number possible), but in its intuitive appeal, and most of all, its usefulness to the understanding.

As an application of his Material Theory of Induction, Norton (2018; manuscript) argues that the correct inductive logic for a fair infinite lottery, and also for evaluating eternal inflation multiverse models, is radically different from standard probability theory. This is due to a requirement of label independence. It follows, Norton argues, that finite additivity fails, and any two sets of outcomes with the same cardinality and co-cardinality have the same chance. This makes the logic useless for evaluating multiverse models based (...) on self-locating chances, so Norton claims that we should despair of such attempts. However, his negative results depend on a certain reification of chance, consisting in the treatment of inductive support as the value of a function, a value not itself affected by relabeling. Here we define a purely comparative infinite lottery logic, where there are no primitive chances but only a relation of ‘at most as likely’ and its derivatives. This logic satisfies both label independence and a comparative version of additivity as well as several other desirable properties, and it draws finer distinctions between events than Norton's. Consequently, it yields better advice about choosing between sets of lottery tickets than Norton's, but it does not appear to be any more helpful for evaluating multiverse models. Hence, the limitations of Norton's logic are not entirely due to the failure of additivity, nor to the fact that all infinite, co-infinite sets of outcomes have the same chance, but to a more fundamental problem: We have no well-motivated way of comparing disjoint countably infinite sets.

Recent research in ethics education shows a potentially problematic variation in content, curricular materials, and instruction. While ethics instruction is now widespread, studies have identified significant variation in both the goals and methods of ethics education, leaving researchers to conclude that many approaches may be inappropriately paired with goals that are unachievable. This paper speaks to these concerns by demonstrating the importance of aligning classroom-based assessments to clear ethical learning objectives in order to help students and instructors track their progress (...) toward meeting those objectives. Two studies at two different universities demonstrate the usefulness of classroom-based, formative assessments for improving the quality of students’ case responses in computational modeling and research ethics.

ABSTRACTJohn Campbell’s Present State of Europe has been viewed, particularly by Guido Abbattista, as a change in Campbell’s view on British intervention on the continent. Campbell certainly alters his position from a conventional ‘Country’ and ‘Tory’ critique of British interventionism to acceptance, but this shift aligns him more closely with the Bolingbrokean political philosophy that undergirds much of his early thought as he accommodates this political philosophy to the dominant theory of foreign policy of his day, ‘balance of power’. Campbell (...) articulates a moderate, Tory view of balance of power by drawing upon Samuel Pufendorf’s idea of states-system, which allows Campbell to extend his ‘Country’-Bolingbrokean philosophy from inside to outside the state. By extending his views outside the state, Campbell indicates how continental intervention not only may be required based upon a nation’s fluctuating, indeterminate circumstances but also may be needed to protect far-flung subjects within an expanding British Empire.

In standard probability theory, probability zero is not the same as impossibility. But many have suggested that only impossible events should have probability zero. This can be arranged if we allow infinitesimal probabilities, but infinitesimals do not solve all of the problems. We will see that regular probabilities are not invariant over rigid transformations, even for simple, bounded, countable, constructive, and disjoint sets. Hence, regular chances cannot be determined by space-time invariant physical laws, and regular credences cannot satisfy seemingly reasonable (...) symmetry principles. Moreover, the examples here are immune to the objections against Williamson’s infinite coin flips. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Painting Outside the Lines: Patterns of Creativity in Modern ArtMatthew ZiffPainting Outside the Lines: Patterns of Creativity in Modern Art, by David W. Galenson. Cambridge: Harvard University Press, 2001, 272 pp., $29.95.The relationship between the market value of paintings and the chronological point in an artist's working life when the paintings were produced is the driving mechanism for exploring creativity and innovation in David W. Galenson's book "Painting (...) Outside the Lines: Patterns of Creativity in Modern Art. The working thesis of this book is that Modern artists have worked creatively and innovatively in one of two distinctly different manners. The terminology Galenson uses to describe these distinct ways of working are "finders" and "seekers." Finders are artists like Pablo Picasso, who at age 26, make startling and important innovations with little advance indication that such a burst is about to take place. Seekers are artists like Paul Cezanne, whospend their entire working lives engaged in the pursuit of a singular approach or achievement. The differences between these methodologies are carefully presented through the details of the working lives of a variety of Modern artists. French nineteenth century and early twentieth-century artists and mid-twentieth-century American artists are used as the source data for these comparisons.Early in the book Galenson presents lists of chronological events within the lives of artists and market valuation of their work within this chronology. The dramatic clarity of the relationships presented in this data sets the stage for the detailed information that follows. Factors that in some cases only partly, and in others nearly completely, explain an artist's way of working are offered through biographic information, information about the aesthetic and cultural milieu, and about the economic and educational structures that are predominant during the relevant time in the life of the artist.The relationship between the aesthetic and cultural milieu surrounding an artist and the capacity or inclination of an artist to be innovative is an important aspect of the book's analysis. The scope of the book is limited to Modern artists because of the shift that took place at the outset of Modern art, during the mid 1860s, that brought a strong emphasis on innovation and change for their own sake as an important characteristic within a work of art. This emphasis "created incentives for painters to produce new approaches to art" (p. 111). Prior to the time of Modern art, innovation and change were often unnecessary for an artist to be successful. Modern art introduced the demand that innovation and change be necessary ingredients in art, and therefore the search for innovation became a significant element within the work of many artists. The manner in which this search took place, as presented through the data at hand, reveals how individual artists viewed the need for innovation and change within their own [End Page 123] work. Paul Cezanne, for example, was aware of the impact that his painting was having on the art world, but he insisted that he was not yet finished with discoveries that would reveal the truest expression of his beliefs about aesthetic expression.In the American movement, "Abstract Expressionism," Galenson finds a useful counter example to the art scene in Paris. In the United States, especially during the 1940s and 1950s — the peak years of creative output by Abstract Expressionist artists — the demand for their work was quite low. There were few economically viable outlets for the work of de Kooning, Pollack, Rothko, and the others of this group. Consequently there is a shift in the chronological point at which these artists achieve market value success. Nearly all of these artists receivedrecognition at an older age than the French artists of the late nineteenth and early twentieth centuries.The thesis of the book, that there are two fundamentally different ways of working to produce works of art, is directly applicable to, and useful in, exploring issues of teaching and learning in design education. As a teacher of interior architecture I was interested to follow the details that Galenson presented in support of his analysis of the careers of numerous Modern artists.

Counterfactual thinking involves imagining hypothetical alternatives to reality. Philosopher David Lewis argued that people estimate the subjective plausibility that a counterfactual event might have occurred by comparing an imagined possible world in which the counterfactual statement is true against the current, actual world in which the counterfactual statement is false. Accordingly, counterfactuals considered to be true in possible worlds comparatively more similar to ours are judged as more plausible than counterfactuals deemed true in possible worlds comparatively less similar. Although Lewis (...) did not originally develop his notion of comparative similarity to be investigated as a psychological construct, this study builds upon his idea to empirically investigate comparative similarity as a possible psychological strategy for evaluating the perceived plausibility of counterfactual events. More specifically, we evaluate judgments of comparative similarity between episodic memories and episodic counterfactual events as a factor influencing people's judgments of plausibility in counterfactual simulations, and we also compare it against other factors thought to influence judgments of counterfactual plausibility, such as ease of simulation and prior simulation. Our results suggest that the greater the perceived similarity between the original memory and the episodic counterfactual event, the greater the perceived plausibility that the counterfactual event might have occurred. While similarity between actual and counterfactual events, ease of imagining, and prior simulation of the counterfactual event were all significantly related to counterfactual plausibility, comparative similarity best captured the variance in ratings of counterfactual plausibility. Implications for existing theories on the determinants of counterfactual plausibility are discussed. (shrink)
