This paper discusses comparison classes—sets that relativize the interpretation of gradable adjectives, often specified with for-clauses as in John is smart for a linguist. Such a discussion ultimately lends support to the thesis that scales, degrees, measure functions, and linear orders are grammatically derived from more basic relations between individuals. Three accounts of comparison classes are compared and evaluated. The first proposes that such classes serve as an argument to a function that determines a standard of comparison. The second (...) maintains that these classes restrict the domain of a measure function used to map entities to degrees. The third proposes that these classes limit the kind of individuals that participate in a binary relation; this relation is then used in the construction of a scale and a measure function. It is this third account that is most consistent with the empirical data. It can explain how comparison classes fix a standard of comparison, induce presuppositions concerning the comparative subjects, and induce incommensurability in comparative constructions. (shrink)

Near the homes of photographers John Willis and Tom Young is a paper mill that sits in the otherwise pristine and picturesque climes of western Massachusetts. For Willis and Young, this site is one of both aesthetic and philosophical contradictions: despite its verdant locale, the mill—with its ominous smoke stacks and countless bales of discarded paper—brings to mind the dreariness of industrialization and the impermanence of life itself. But the factory is actually one where such litter is reborn as (...) reusable paper. Willis and Young’s stunning black-and-white images, collected in this unforgettable volume, transform this mill and the innumerable mounds of recyclable waste it processes daily into an indelible and evocative landscape. Recycled Realities is not a jeremiad foretelling the consequences of excessive waste, rampant pollution, or unbridled consumption, but rather a profound meditation on the hidden meanings and connections that linger beneath the debris and detritus of everyday life. These astonishing and often surreal photos of discarded paper from the printed world trace the processes of emergence, revelation, and redemption that make the cycle of life possible. In their photographs, Willis and Young take that which we have discarded and create new forms of being in and of themselves: vibrant and ultimately life-affirming portraits of who we are as people and the realities that we constantly build—and rebuild—all around us.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Tolstoy’s Art and Thought, 1847–1880John GoodliffeTolstoy’s Art and Thought, 1847–1880, by Donna Tussing Orwin; viii & 296 pp. Princeton: Princeton University Press, 1993, $35.00.In the opening words of the introduction, “this book is an attempt to reconstruct the ideas that led Tolstoy to write the masterpieces of his youth and middle age” (p. 3). Covering the first three decades of Tolstoy’s creative life, it focuses first on his (...) “initial vision” in the 1850s, principally derived from Rousseau’s belief in the superiority of natural morality over the artificial values created by so-called civilization. Then, by way of an analysis of The Cossacks (1863), it seeks to show how Tolstoy came to see that “natural morality was not enough” (p. 96). So, in War and Peace, he tried to depict a world in which human beings were at one with nature, where everything, even war, was natural and part of God’s purpose, so that there was no dichotomy between what is natural and what is civilized. The key word for War and Peace is thus sopriaganie—“linkage.”By the 1870s, when Tolstoy was writing Anna Karenina, he no longer saw God as directly involved in human affairs. Now God was “farther away, but higher and more indubitable” (from a letter to the poet Fet). From this shift in thinking is derived the “drama” of Anna Karenina, as distinct from the “epic” oneness of War and Peace. Whereas in the latter work Tolstoy wanted to see all aspects of life, human or otherwise, in harmony, in Anna Karenina, partly under the baleful influence of Schopenhauer, he came to depict an essential disharmony in life, which he and Levin sought vainly to resolve. Having reached this impasse, Tolstoy abandoned fiction as a medium for his ideas and turned to direct expression of them in essays, tracts, and the like.In writing her book Orwin set herself the virtually impossible task of presenting Tolstoy’s work “as he may have understood it himself” (p. 5). She succeeds in this as well as may be reasonably expected, largely through a detailed analysis of the relevant works of fiction and by drawing on Tolstoy’s correspondence with, for example, N. N. Strakhov. This type of approach is a risky one, since it inevitably treats the fictional texts principally as vehicles for philosophy, when clearly they are much more than that. It is to her credit that, in spite of this, Orwin generally succeeds in her task, although her bias is evident in the bold statement that without “moral law,” Anna Karenina would be Dallas (p. 207)! The other risk is that of treating the fictional texts as though they are somehow separate from Tolstoy the human being, as opposed to Tolstoy the thinker. In her conclusion Orwin refers belatedly and almost incidentally to Tolstoy’s marriage, his family and his growing older. But these factors were surely more crucial for the development of his ideas than she seems to have allowed for; the optimism of War and Peace reflecting the harmony of the early years of his marriage and the darker notes of Anna [End Page 166] Karenina indicating growing disillusion as the relationship between him and his wife lost its early bloom and Tolstoy approached his fifties.Deserving of fuller treatment too were the currents of thought in Russian intellectual circles in the 1860s and 70s which formed an essential background for Tolstoy’s ideas. These too are accorded only quite brief mention. In fact, the commentary on the fictional works, impressive in its depth, tends to be almost too detailed, in places verging on the repetitious. The book could have been more satisfactory if the detailed textual commentary had been more concise and the broader considerations given more extensive analysis. But Orwin’s decision to use a comparatively narrow focus was clearly deliberate and, if we accept its limitations, we can still recognize the importance of her book for Tolstoy studies.John GoodliffeUniversity of Canterbury, New ZealandCopyright © 1995 The Johns Hopkins University Press...

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 42.2 (2004) 219-220 [Access article in PDF] Jack Zupko. John Buridan: Portrait of a Fourteenth-Century Arts Master. Notre Dame: University of Notre Dame Press, 2003. Pp. xix + 446. Cloth, $70.00. Paper, $40.00. What does the name "John Buridan" call to mind? For many, including medievalists, not much at all—at best, perhaps, a set of apparently unrelated ideas: nominalism; an impetus (...) theory of projectile motion; and a peculiar account of the will (although "Buridan's ass," the indecisive donkey caught between two equally appetizing bales of hay, is not found in Buridan's writing). In correcting this ignorance—an injustice to arguably the most famous and influential philosopher of the early-to-mid-fourteenth century—the temptation might have been to articulate Buridan's "positions" on "the big questions," allowing readers to fit Buridan into received categories. Thankfully, the present work, the first book-length study of Buridan in any language, resists this temptation. The John Buridan that emerges from Jack Zupko's skillful "exercise in philosophical portraiture" doesn't serve to simply fill gaps in our awareness of the historical record, but to enlighten and challenge our understanding of the practice of philosophy and the study of its history.Zupko emphasizes throughout that Buridan was a teacher, a master of arts in Paris. Buridan's pedagogical concerns help make sense of his central work in logic. As the basis for his arts lectures, Buridan chose Peter of Spain's Summulae Logicales, but in commenting on Peter, Buridan moves beyond creative exegisis to comprehensive renovation. Buridan (c. 1300-c. 1361) naturally wanted to accommodate terminist or via moderna supposition theory; but more importantly, he wanted a logic text that would set out a general plan of philosophical inquiry, "a compendium of methods, a 'how-to' book for the philosopher" (135). Buridan thus designed his own Summulae de Dialectica as a new authoritative logic text, and Zupko persuasively argues that its "nominalism" should be understood as less a set of doctrines in theoretical logic, than a program of logical practice, an education in logic as the ars artium, the universal intellectual tool.Zupko's portrait of "Buridan's vision of the philosophical enterprise" is thus appropriately divided into two parts. The first summarizes Buridan's method as described in the individual treatises of his Summulae. The second displays the method in practice, rehearsing and evaluating some of Buridan's arguments on various subjects. Many scholars will gravitate first to the latter part, where Zupko offers important interpretations and clarifications of Buridan's views. In these chapters, Zupko helps us to appreciate, among other things: how the problem of universals served to help Buridan define the scope of philosophy (ch. 10); the philosophical modesty of Buridan's account of the intellectual soul's presence in the body (ch. 11); the relationship between Buridan's epistemology and the skepticism of his Parisian contemporary Nicholas of Autrecourt (ch. 12); the sense in which Buridan is an "empiricist," viz an epistemic naturalist and reliabilist (ch. 13); how Buridan regarded moral psychology as applied physics, treating virtue as a kind of impetus (ch. 14); how Buridan's account of freedom can be regarded as a "perfection" of Thomistic intellectualism (ch. 15).Throughout these discussions, Zupko always keeps in sight his larger purpose of illustrating Buridan's conception of philosophical inquiry. Zupko makes much of the fact that [End Page 219] Buridan never wrote as a theologian, remaining his entire career in the arts faculty, where he wanted logic to organize secular inquiry. As Zupko notes, in this way Buridan's scholastic project seems to prefigure the "modern." But Buridan seems modern in another way as well. As Zupko points out in his "Introduction," though a cleric, Buridan never joined a religious order, so that his ideas developed independently of the Franciscan and Dominican traditions. He was, then, a teacher without a tradition—at least without deliberate allegiance to tradition, although he was in many ways the product of traditional scholastic intellectual discipline.Perhaps this...

In lieu of an abstract, here is a brief excerpt of the content:FROM CAIN AND ABEL TO ESAU AND JACOB Angel Barahona UniversidadComplutense, Madrid The theme of twins or of enemy brothers is one which fascinates anthropologists owing to its frequency, the beauty of its mythopoetic settings, and its social significance. The theme always appears in relation to fratricidal violence, and is always linked to myths offoundation or origin. Clyde Kluckhohn in his book about brothers "born in immediate sequence" reminds (...) us that the death of one of them brings with it a momentary peace, the foundation ofa new social order. Thus it is not the fact ofbeing twins, or antagonistic brotherhood per se which is the key to the stories, but violence: Twins are impure in the same way that a warrior steeped in carnage is impure, or an incestuous couple, or a menstruating woman. All forms of violence lead back to violence. We overlook this fact because the primitive concept of a link between the loss ofdistinctions and violence is strange to us; butwe need only consider the calamities primitive people associate with twins to perceive the logic of this concept. Deadly epidemics can result from contact with twins, as can mysterious illnesses mat cause sterility in women and animals. Even more significant to us is the role oftwins in provoking discord among neighbors, a fatal collapse of ritual, the transgression of interdictions—in sort, their part in instigating asacrificial crisis....Behindthe image oftwins lurks the baleful aspectofthesacred, perceived as a disparate but formidableunified force. (Girard 1977, 58) All the mythological, literaryand historical accounts oftwinswhichwe have involve bloody conflict: Eteocles and Polyneices, Romulus and Remus, Richard the Lion Heart and John Lackland, and so on. To a 2 Angel Barahona surprising extent even the development of the different stories is similar. When Polynices departs from Thebes leaving his sister there, hoping to reign through her, he takes with him his fraternal conflict as if it were an attribute of his being. Wherever he goes his brother appears to him, and will oppose him to the death. When an oracle announced to Adrastrus that his two daughters would marry, respectively, a lion and a wild boar, animals which are different in their appearance but identical in their violence, it was presaging fraternal conflict. In Euripides' The Suppliant Women, the king tells how he came upon his sons-in-law. At his door, one night, Polynices and Tideus, both reduced to poverty, were quarreling furiously over possession ofa camp bed. Their brotherhood by virtue ofmarriage with two sisters brings them within the fraternalcategory, likeOedipus and Creon, orDionysus and Pentheus, rival cousins. A plot of land or a kingdom, a woman or an object, the status of firstborn or an unjust inheritance, all give pretexts for conflict. We cannot avoid conflict when desires converge on the same object. It is difficult for the brothers to be aware of their symmetry, their reciprocity, the intense violence which is hidden behind their brotherhood,—an awareness which might spare them their confrontations—because they never occupy the same positions atthe same time. The reciprocity is real, but it is the sum of non-reciprocal moments. The antagonists occupy the same positions in time, but successively, not simultaneously. The same acts and the same sentiments appear in cyclical alternation, but the brothers cannot directly observe their own reciprocity, and thus their identical nature, because they seem to be differentiated by the role which each one plays. Cain and Abel There are many stories ofconfrontations between brothers in Scripture, including those related to the rights of the first born. From Genesis 4,5 onwards we see how these are an interminable source ofconflicts. The first example, Cain and Abel: "And the LORD had regard for Abel and his offering, but for Cain and his offering he had no regard. So Cain was very angry, and his countenance fell" anticipates the themes ofthe blessing and the looking at the face. And we can observe the games of symmetry with the language: "the LORD had regard for Abel and his offering, but forCain and his offering he had no regard." Cain and Abel are presented as an agriculturalist and as a shepherd respectively, two forms ofsocial life. In this quarrel... (shrink)

Recent progress in artificial intelligence (AI) has drawn attention to the technology’s transformative potential, including what some see as its prospects for causing large-scale harm. We review two influential arguments purporting to show how AI could pose catastrophic risks. The first argument — the Problem of Power-Seeking — claims that, under certain assumptions, advanced AI systems are likely to engage in dangerous power-seeking behavior in pursuit of their goals. We review reasons for thinking that AI systems might seek power, that (...) they might obtain it, that this could lead to catastrophe, and that we might build and deploy such systems anyway. The second argument claims that the development of human-level AI will unlock rapid further progress, culminating in AI systems far more capable than any human — this is the Singularity Hypothesis. Power-seeking behavior on the part of such systems might be particularly dangerous. We discuss a variety of objections to both arguments and conclude by assessing the state of the debate. (shrink)

Orthodox decision theory gives no advice to agents who hold two goods to be incommensurate in value because such agents will have incomplete preferences. According to standard treatments, rationality requires complete preferences, so such agents are irrational. Experience shows, however, that incomplete preferences are ubiquitous in ordinary life. In this paper, we aim to do two things: (1) show that there is a good case for revising decision theory so as to allow it to apply non-vacuously to agents with incomplete (...) preferences, and (2) to identify one substantive criterion that any such non-standard decision theory must obey. Our criterion, Competitiveness, is a weaker version of a dominance principle. Despite its modesty, Competitiveness is incompatible with prospectism, a recently developed decision theory for agents with incomplete preferences. We spend the final part of the paper showing why Competitiveness should be retained, and prospectism rejected. (shrink)

A simple argument suggests that we can fruitfully model advanced AI systems using expected utility theory. According to this argument, an agent will need to act as if maximising expected utility if they’re to avoid exploitation. Insofar as we should expect advanced AI to avoid exploitation, it follows that we should expected advanced AI to act as if maximising expected utility. I spell out this argument more carefully and demonstrate that it fails, but show that the manner of its failure (...) is instructive: in exploring the argument, we gain insight into how to model advanced AI systems.

Comparative constructions form two classes, those that permit direct comparisons (comparisons of measurements as in Seymour is taller than he is wide) and those that only allow indirect comparisons (comparisons of relative positions on separate scales as in Esme is more beautiful than Einstein is intelligent). In contrast with other semantic theories, this paper proposes that the interpretation of the comparative morpheme remains the same whether it appears in sentences that compare individuals directly or indirectly. To develop a unified account, (...) I suggest that all comparisons (whether in terms of height, intelligence or beauty) involve a scale of universal degrees that are isomorphic to the rational (fractional) numbers between 0 and 1. Crucial to a unified treatment, the connection between the individuals being compared and universal degrees involves two steps. First individuals are mapped to a value on a primary scale that ranks individuals with respect to the gradable property (whether it be height, beauty or intelligence). Second, the value on the primary scale is mapped to a universal degree that encodes the value’s relative position on the primary scale. Direct comparison results if measurements such as seven feet participate in the primary scale (as in Seven feet is tall). Otherwise the result is an indirect comparison. (shrink)

Andy Egan has recently presented a prominent objection to causal decision theory. However, in this paper, I argue that this objection fails if CDT’s proponent accepts the plausible view that decision-theoretic options are intentions. This result both provides a defence of CDT against a prominent objection and highlights the importance of resolving the nature of decision-theoretic options.

In a letter to Wlodek Rabinowicz, David Lewis introduced a decision scenario that he described as “much more problematic for decision theory than the Newcomb Problems”. This scenario, which involves an agent with foreknowledge of the outcome of some chance process, has received little subsequent attention. However, in one of the small number of discussions of such cases, Huw Price's Causation, Chance and the Rational Significance of Supernatural Evidence it has been argued that cases of this sort pose serious problems (...) for causal decision theory. In this paper, I will argue that these problems can be overcome: scenarios of this sort do not pose fatal problems for this theory as there are versions of CDT that reason appropriately in these cases. However, I will also argue that such cases push us toward a particular version of CDT developed by Wlodek Rabinowicz. (shrink)

A prominent philosophical debate concerns whether we should accept causal decision theory or evidential decision theory as our best theory of rational choice. However, instead of accepting one of these theories at the expense of the other, an alternative would be to accept that both theories play a partial role in the true account of rational choice. In this paper, I defend a pluralist account of this sort. In particular, I argue that rational permissibility is an indeterminate notion, with EDT (...) and CDT each corresponding to one sharpening of this notion. (shrink)

Causal decision theory is one of our most prominent theories of rational choice and the “why ain’cha rich?” argument is one of the most prominent objections to this theory. According to WAR, CDT is not an adequate theory of rational choice because it leads agents to make decisions that foreseeably leave them less well off than agents that decide in some other manner. Some philosophers take WAR to decisively undermine CDT. On the other hand, others take WAR to fail to (...) resolve the debate over CDT’s adequacy. In this paper, I will defend this second view: WAR does not resolve the debate at hand but instead leads to deadlock. Then, in the second half of this paper, I will show that this deadlock is not broken by a recent variant on WAR due to Caspar Hare and Brian Hedden. Not only does this result have implications for the debate over CDT’s adequacy but this discussion also casts light on the broader success/rationality link. (shrink)

Various people have claimed that some cases involve indeterminate permissibility. However, it’s unclear what guidance one can take away from this fact: are indeterminately permissible options choiceworthy and if so when? In this paper, I present a counterexample that undermines two existing responses to this question and I then present two alternative solutions that avoid this counterexample.

Expressions like "two novels" are traditionally taken to convey information about cardinality and are analyzed using a cardinality function. Salmon (Philosop Perspect 11:1–15, 1997), Liebesman (Australasian J Philos 93:21–42, 2015; Philos’ Impr 16:1–25, 2016; In D. W. Zimmerman (ed.), Oxford studies in metaphysics, Oxford University Press, Oxford, forthcoming), and Haida and Trinh (in: Dočekal, Wagiel (eds) Formal approaches to number in Slavic and beyond, Language Science Press, Berlin, 2001) argue against this traditional account, claiming that it can’t explain our use (...) of expressions like "two and a half novels". According to them, the proper analysis of such expressions requires a partiality measure, which maps entities to rational numbers such as 2.5. In this paper, we set out to defend the traditional account. To do so, we demonstrate that an analysis based on a partiality measure is inconsistent with the truth conditions of plural comparatives and equatives. We also show that such an account doesn’t provide an adequate analysis for expressions like "two novels and a half", nor for their French counterparts (e.g., "deux romans et demi"). Critically, such expressions contain no constituent that could refer to the number 2.5. We provide an alternative analysis for all these expressions, based on cardinality and an operation of non-overlapping summation. (shrink)

Some take seriously the possibility of artificial intelligence (AI) takeover, where AI systems seize power in a way that leads to human disempowerment. Assessing the likelihood of takeover requires answering empirical questions about the future of AI technologies and the context in which AI will operate. In many cases, philosophers are poorly placed to answer these questions. However, some prior questions are more amenable to philosophical techniques. What does it mean to speak of AI empowerment and human disempowerment? And what (...) empirical claims must hold for the former to lead to the latter? In this paper, I address these questions, providing foundations for further evaluation of the likelihood of takeover. (shrink)

Why should we typically act in accordance with our resolutions when faced with the temptation to do otherwise? A much-maligned view suggests that we should do so because resolutions themselves provide us with reasons for action. We defend a version of this view, on which resolutions provide second-order reasons. This account avoids the objections typically taken to be fatal for the view that resolutions are reasons, including the prominent bootstrapping objections.

In the so-called reverse proportional reading :53, 1997), the truth conditions of statements of the form many/few \\ appear to make reference to the ratio of the individuals that are in the extensions of both \ and \ to the individuals that are in the extension of \. The analysis of such readings is controversial. One prominent approach assumes they are a symptom of many and few making reference to a context dependent standard of comparison. We observe that this initially (...) attractive approach systematically undergenerates, failing to capture pervasive reverse proportionality in environments that remove context dependency of the standard. Instead, we propose that reverse proportionality in such cases can arise from the underspecification of the measure function underlying the meanings of many and few. (shrink)

Morally supererogatory acts are those that go above and beyond the call of duty. More specifically: they are acts that, on any individual occasion, are good to do and also both permissible to do and permissible to refrain from doing. We challenge the way in which discussions of supererogation typically consider our choices and actions in isolation. Instead we consider sequences of supererogatory acts and omissions and show that some such sequences are themselves problematic. This gives rise to the following (...) puzzle: what problem can we have with a sequences of actions if each individual act or omission is itself permissible? In this paper, we develop a response to this question, by exploring whether solutions analogous to those proposed in the rational choice literature are available in the case of supererogatory sequences. Our investigation leads us to the view that making sense of the supererogatory requires accepting that there are global moral norms that apply to sequences of acts alongside the local moral norms that apply to individual acts.

ABSTRACT While pragmatic arguments are traditionally seen as supporting decision theory, recent discussions suggest the possibility of pragmatic arguments against this theory. I respond to two such arguments, and clarify what it would take for arguments of this sort to succeed.

In this examination of the practical and ethical implications of slave redemption the authors deal with questions such as: Does redeeming slaves actually increase the demand for -and so the number of- slaves? And what about cases where it is far from clear that redemption will improve the material condition or increase the real freedom, of a slave?

In recent years, act-utilitarianism has been distinguished from rule-utilitarianism. We may say that act-utilitarianism is the thesis that a particular act is right if and only if its utility – that is contribution towards intrinsically good states of affairs – is no less than that of some alternative act. Rule-utilitarianism is the thesis that an act is right if and only if it conforms to a rule somehow grounded in utility. The present paper concerns one type of argument sometimes used (...) as an attempt to show that act-utilitarianism cannot be an adequate ethical theory. Arguments of this type are characterized by an emphasis on practical difficulties involved in, or paradoxes arising out of, the attempt to apply act-utilitarianism theory to concrete moral situations.

Dual labor market theory, developed as an explanation of underemployment and poverty within the economy, may also be applied to the illicit economy of crime. Criminal careers are differentiated into a primary sector, with occupational stability, low failure rate, and high chances of advancement; and a secondary sector, with instability, high failure rate, and lack of "market" control. The attraction of criminal careers, the likelihood of incarceration, and the effects of law enforcement are best understood in these contexts.
