A defining characteristic of Alzheimer’s disease is difficulty in retrieving semantic memories, or memories encoding facts and knowledge. While it has been suggested that this impairment is caused by a degradation of the semantic store, the precise ways in which the semantic store is degraded are not well understood. Using a longitudinal corpus of semantic fluency data, we derive semantic network representations of patients with Alzheimer’s disease and of healthy controls. We contrast our network-based approach with analyzing fluency data with (...) the standard method of counting the total number of items and perseverations in fluency data. We find that the networks of Alzheimer’s patients are more connected and that those connections are more randomly distributed than the connections in networks of healthy individuals. These results suggest that the semantic memory impairment of Alzheimer’s patients can be modeled through the inclusion of spurious associations between unrelated concepts in the semantic store. We also find that information from our network analysis of fluency data improves prediction of patient diagnosis compared to traditional measures of the semantic fluency task. (shrink)

ABSTRACT:In this address, I distinguish and explore three conceptions of wages. A wage is a reward, given in recognition of the performance of a valued task. It is also an incentive: a way to entice workers to take and keep jobs, and to motivate them to work hard. Finally, a wage is a price of labor, and like all prices, conveys valuable information about relative scarcity. I show that each conception of wages has its own normative logic, or appropriate justification, (...) and these logics can come apart. This explains some of the debate about wages and makes the project of justifying a wagesimpliciterdifficult. I identify which logic we should choose, since we must choose, and say what this means for how we should think about the justification of pay. (shrink)

Husserl is well known for his critique of the “mathematizing tendencies” of modern science, and is particularly emphatic that mathematics and phenomenology are distinct and in some sense incompatible. But Husserl himself uses mathematical methods in phenomenology. In the first half of the paper I give a detailed analysis of this tension, showing how those Husserlian doctrines which seem to speak against application of mathematics to phenomenology do not in fact do so. In the second half of the paper I (...) focus on a particular example of Husserl’s “mathematized phenomenology”: his use of concepts from what is today called dynamical systems theory. (shrink)

Famous results by David Lewis show that plausible-sounding constraints on the probabilities of conditionals or evaluative claims lead to unacceptable results, by standard probabilistic reasoning. Existing presentations of these results rely on stronger assumptions than they really need. When we strip these arguments down to a minimal core, we can see both how certain replies miss the mark, and also how to devise parallel arguments for other domains, including epistemic “might,” probability claims, claims about comparative value, and so on. A (...) popular reply to Lewis's results is to claim that conditional claims, or claims about subjective value, lack truth conditions. For this strategy to have a chance of success, it needs to give up basic structural principles about how epistemic states can be updated—in a way that is strikingly parallel to the commitments of the project of dynamic semantics.

In this introduction to part 3 of the Common Knowledge symposium “Antipolitics,” the journal's editor argues that, apart from sortition, the best guarantees of safety in a democracy are, first, to augment judicial oversight of all political processes and, second, to exclude politicians from the process of selecting judges. “There can never be too much judicial interference,” he writes, “in what politicians regard as their domain.” The author reached this conclusion during attempts by the newly elected Israeli government, in the (...) spring of 2023, to make itself absolute by eliminating checks on its conduct that the Supreme Court had been developing and applying since the 1950s. Traditional Jewry and Judaism being notoriously hypernomian, the resistance to legality on the part of the ruling coalition has conveyed an aura of antinomian heresy. The choice in Israel appears to be between antipolitics and antinomianism, rather than between Left and Right politically—and the antipolitical model in Israel of a superintendent judiciary and an autonomous attorney general is arguably superior to the American prototype, even from the perspective (“all men are created equal..., endowed by their Creator with certain unalienable Rights”) that we have come to regard as quintessentially American.

I examine three ‘anti-object’ metaphysical views: nihilism, generalism, and anti-quantificationalism. After setting aside nihilism, I argue that generalists should be anti-quantificationalists. Along the way, I attempt to articulate what a ‘metaphysically perspicuous’ language might even be.

I show how existing concepts of supervenience relate to two more fundamental ontological relations: determination and dependence. Determination says that the supervenient properties of a thing are a function of its base properties, while dependence says that having a supervenient property implies having a base property. I show that most varieties of supervenience are either determination relations or determination relations conjoined with dependence relations. In the process of unpacking these connections I identify limitations of existing concepts of supervenience and provide (...) ways of overcoming them. What results is a more precise, flexible, and powerful set of tools for relating sets of properties than current concepts of supervenience provide. I apply these tools to a recalcitrant problem in the physicalism literature – the problem of extras. (shrink)

Informed consent is the single most important concept for understanding decision-making capacity. There is a steady pull in the clinical world to transform capacity into a technical concept that can be tested objectively, usually by calling for a psychiatric consult. This is a classic example of medicalization. In this article I argue that is a mistake, not just unnecessary but wrong, and explain how to normalize capacity assessment.Returning the locus of capacity assessment to the attending, the primary care doctor, and (...) even to ethics consultation in today's environment will require a substantial effort to undo a strong but illusory impression of capacity assessment. Hospital attorneys as well as clinical ethicists with a sophisticated understanding of health law can be in the vanguard of this reorientation. (shrink)

The aim of this paper is to examine the usefulness of the Machamer, Darden, and Craver (2000) mechanism approach to gaining an understanding of explanation in cognitive neuroscience. We argue that although the mechanism approach can capture many aspects of explanation in cognitive neuroscience, it cannot capture everything. In particular, it cannot completely capture all aspects of the content and significance of mental representations or the evaluative features constitutive of psychopathology.

Online retailers are using advances in data collection and computing technologies to “personalize” prices, i.e., offer goods for sale to shoppers at their reservation prices, or the highest price they are willing to pay. In this paper, I offer a criticism of this practice. I begin by putting online personalized pricing in context. It is not something entirely new, but rather a kind of price discrimination, a familiar pricing practice. I then offer a fairness-based argument against it. When an online (...) retailer personalizes prices, it competes unfairly for the social surplus created by a transaction. I defend this argument against objections, and offer a simple remedy: online retailers should either disclose that they are personalizing prices, or stop doing so. (shrink)

“There are no gaps in logical space,” David Lewis writes, giving voice to sentiment shared by many philosophers. But different natural ways of trying to make this sentiment precise turn out to conflict with one another. One is a *pattern* idea: “Any pattern of instantiation is metaphysically possible.” Another is a *cut and paste* idea: “For any objects in any worlds, there exists a world that contains any number of duplicates of all of those objects.” We use resources from model (...) theory to show the inconsistency of certain packages of combinatorial principles and the consistency of others.

Suppose that all non-qualitative facts are grounded in qualitative facts. I argue that this view naturally comes with a picture in which trans-world identity is indeterminate. But this in turn leads to either pervasive indeterminacy in the non-qualitative, or else contingency in what facts about modality and possible worlds are determinate.

Based on evidence from press articles covering 39 corporate fraud cases that went public during the period 1992-2005, the objective of this article is to examine the role of managers' behavior in the commitment of the fraud. This study integrates the fraud triangle (FT) and the theory of planned behavior (TPB) to gain a better understanding of fraud cases. The results of the analysis suggest that personality traits appear to be a major fraud-risk factor. The analysis was further validated through (...) a quantitative analysis of keywords which confirmed that keywords associated with the attitudes/rationalizations component of the integrated theory were predominately found in fraud firms as opposed to a sample of control firms. The results of the study suggest that auditors should evaluate the ethics of management through the components of the TPB: the assessment of attitude, subjective norms, perceived behavioral control and moral obligation. Therefore, it is potentially important that the professional standards that are related to fraud detection strengthen the emphasis on managers' behavior that may be associated with unethical behavior.

Though responses to Stout's book, "Democracy and Tradition," have touched on his discussion of rights, none has comprehensively examined his position on the subject. Having endorsed several objections Stout raises against some influential views on democracy and rights, this article proceeds to criticize Stout's description and theoretical account of the natural and human rights traditions. The central argument is that Stout cannot successfully both affirm the traditions and adhere to his account.

The existence of mereological sums can be derived from an abstraction principle in a way analogous to numbers. I draw lessons for the thesis that “composition is innocent” from neo-Fregeanism in the philosophy of mathematics.

What designers do and how we all, as users of designed things, live with their products raises fundamental philosophical questions about how we should live, and how the nature of design work and good design relates to our lives. Jeffrey Petts presents a holistic and pragmatist approach to the philosophy of design. Acknowledging the importance of function in design without downplaying the aesthetic dimension, Petts relates the manner of evaluating design to the designing process itself as demonstrated in the (...) work of, for example, William Morris, Walter Gropius and Bauhaus, Charles and Ray Eames, and Dieter Rams. This metacritical and everyday approach to the philosophy of design expresses a commitment to real aesthetics, connecting concrete issues in both practice and experience to philosophical ideas, and reveals the role aesthetics plays in considerations about the good life.

The presentation of these two projects the metaLAB (at) Harvard complements Jeffrey Schnapp's interview published in the section Perspectives of this issue of Humanist Studies and the Digital Age. The first project, A Flitting Atlas of the Human Gaze, performs an art historical experiment. The second project, Their Names, is an online Denkmal or monument that visualizes the names of 28,000+ fatal encounters with American police dating from the year 2000 up until the death of George Floyd on May (...) 25, 2020.

We consider how cue-reading, sensory-manipulation, and signaling games may initially evolve from ritualized decisions and how more complex games may evolve from simpler games by polymerization, template transfer, and modular composition. Modular composition is a process that combines simpler games into more complex games. Template transfer, a process by which a game is appropriated to a context other than the one in which it initially evolved, is one mechanism for modular composition. And polymerization is a particularly salient example of modular (...) composition where simpler games evolve to form more complex chains. We also consider how the evolution of new capacities by modular composition may be more efficient than evolving those capacities from basic decisions. (shrink)

Capitalizing on a unique setting in China where auditors disclose their prosocial activities, we examine the role that auditor social responsibility plays in shaping their performance. In one direction, behavior consistency theory implies that individual auditors exhibiting more social commitment in their off-the-job activities behave similarly during engagements, enhancing the quality of their audits. In the other direction, accounting firms’ internal structures along with external disciplinary forces mute the impact of heterogeneous auditor characteristics on their performance. In a staggered difference-in-differences (...) design, we report a significant fall in the magnitude of companies’ discretionary accruals and the incidence of financial reporting irregularities after their auditors begin contributing to social welfare, relative to companies whose auditors refrain from contributing during the same timeframe. Additional evidence implies that the higher audit quality stems from auditors better protecting their independence and improving their competence in the post-contribution period. Collectively, our results provide insights into the importance of auditors’ prosocial attitudes to their external monitoring. (shrink)

“Pragmatic encroachers” about knowledge generally advocate two ideas: (1) you can rationally act on what you know; (2) knowledge is harder to achieve when more is at stake. Charity Anderson and John Hawthorne have recently argued that these two ideas may not fit together so well. I extend their argument by working out what “high stakes” would have to mean for the two ideas to line up, using decision theory.

Two distinguished social and political philosophers take opposing positions in this highly engaging work. Louis P. Pojman justifies the practice of execution by appealing to the principle of retribution while Jeffrey Reiman argues that although the death penalty is a just punishment for murder, we are not morally obliged to execute murderers.

In order to judge whether a theory is empirically adequate one must have epistemic access to reliable records of past measurement results that can be compared against the predictions of the theory. Some formulations of quantum mechanics fail to satisfy this condition. The standard theory without the collapse postulate is an example. Bell's reading of Everett's relative-state formulation is another. Furthermore, there are formulations of quantum mechanics that only satisfy this condition for a special class of observers, formulations whose empirical (...) adequacy could only be judged by an observer who records her measurement results in a special way. Bohm's theory is an example. It is possible to formulate hidden-variable theories that do not suffer from such a restriction, but these encounter other problems. (shrink)

Insofar as empirical inquiry involves the coevolution of descriptive language and theoretical commitments, a satisfactory model of empirical knowledge should describe the coordinated evolution of both language and theory. But since we do not know what conceptual resources we might need to express our future theories or to provide our best future faithful descriptions of the world, we do not now know even what the space of future descriptive options might be. One strategy for addressing this shifting-resource problem is to (...) track the predictive and linguistic dispositions of inquirers rather than to track their theories and conceptual resources directly. Sender-predictor games, a variant of Skyrms–Lewis sender-receiver games, provide very simple models for the coordinated coevolution of predictive and linguistic dispositions. Such models explain how it is possible for predictive and descriptive dispositions of inquirers to coevolve, term-wise incommensurable, but nevertheless descriptively faithful languages, to sequentially evolve, and a sort of underdetermination to occur where inquirers might satisfy their descriptive and predictive aims by revising their linguistic dispositions, their theoretical dispositions, or both. Such models also provide an elementary characterization of what it might mean for descriptions of the world to be faithful and hence for empirical inquiry to be successful. In doing so they provide a relatively weak, but perfectly clear, endogenous account of epistemic norms. (shrink)

Proper functionalism claims that a belief has epistemic warrant only if it’s formed according to the subject’s truth-aimed cognitive design plan. The most popular putative counter-examples to proper functionalism all involve agents who form beliefs in seemingly warrant-enabling ways that don’t appear to proceed according to any sort of design. The Swampman case is arguably the most famous scenario of this sort. However, some proper functionalists accept that subjects like Swampman have warrant, opting instead to adopt a non-standard account of (...) design. But critics of proper functionalism hold that this strategy comes at a high cost: the design-plan condition now seems explanatorily superfluous. James Taylor construes cases like Swampman as posing a dilemma for the proper functionalist: either deny warrant in these cases and concede that proper functionalism doesn’t capture our intuitions, or affirm warrant and undermine the explanatory power of the design-plan condition. Proper functionalists have replied to both horns of this dilemma. Recently, Kenny Boyce and Andrew Moon have argued that warrant-affirming intuitions on cases like Swampman are motivated by a principle that has a clear counter-example. Also, Alvin Plantinga presents a set of cases that supposedly cause problems for any analysis of warrant that lacks a design-plan condition. In this essay, I present a counter-argument to Boyce and Moon’s argument, and show that a more robust reliability condition can accommodate Plantinga’s problem cases. I conclude that we’re left with no good reason to doubt that cases like Swampman raise a troubling dilemma for the proper functionalist. (shrink)
