Research notes of Mark Pettinelli about cognitive science, cognitive psychology.

Using path-breaking discoveries of cognitive science, Mark Johnson argues that humans are fundamentally imaginative moral animals, challenging the view that morality is simply a system of universal laws dictated by reason. According to the Western moral tradition, we make ethical decisions by applying universal laws to concrete situations. But Johnson shows how research in cognitive science undermines this view and reveals that imagination has an essential role in ethical deliberation. Expanding his innovative studies of human reason in Metaphors We (...) Live By and The Body in the Mind, Johnson provides the tools for more practical, realistic, and constructive moral reflection.

Many hold that aesthetic appreciation is sensitive to the authenticity or genuineness of an object. In a recent body of work, Carolyn Korsmeyer has defended the claim that genuineness itself is an aesthetic property. Korsmeyer’s aim is to explain our aesthetic appreciation of objects that afford a sense of being ‘in touch with the past’. In this paper, I argue that genuineness cannot explain our appreciation of these objects. There is no aesthetic experience of the genuine.

Some objects we value because they afford a felt connection with people, events, or places connected with their past. Visiting Canterbury cathedral, you encounter the place where, in 1170, Archbishop Thomas Becket was murdered by four knights of Henry II. Knowing that you are standing in the very place where Becket’s blood was spilled gives the past event a sense of tangible reality. One feels ‘in touch with’ the past; history seems to ‘come alive’. In this paper, I propose an (...) explanation for the phenomenology of such experiences in terms of an imaginative activity that represents what an object is historically connected with as part of the object in the present. One imagines of the site of Becket’s murder Becket being murdered. According to my account, objects that embody their histories are representations in Kendall Walton’s sense: they have the function of serving as props in games of make-believe. (shrink)

Recent increases in the rates of parental refusal of routine childhood vaccination have eroded many countries’ “herd immunity” to communicable diseases. Some parents who refuse routine childhood vaccines do so because they deny the mainstream medical consensus that vaccines are safe and effective. I argue that one reason these vaccine denialists disagree with vaccine proponents about the reasons in favor of vaccination is because they also disagree about the sorts of practices that are conducive to good reasoning about healthcare choices. (...) Vaccine denialists allocate epistemic authority more democratically than do mainstream medical professionals. They also sometimes make truth ascriptions for nonepistemic reasons, fail to recognize legitimate differences in expertiseand competence, and seek uncritical affirmation of their existing beliefs. By focusing on the different epistemic values and practices of vaccine denialists and mainstream medical professionals, I locate my discussion of vaccine denialism within broader debates about rationality. Furthermore, I argue that gender inequality and gendered conceptions of reason are important parts of the explanation of vaccine denialism. Accordingly, I draw upon feminist work—primarily feminist social epistemology—to help explain and evaluate this form of vaccine refusal. (shrink)

I propose a definition of the uncanny: an anxious uncertainty about what is real caused by an apparent impossibility. First, I outline the relevance of the uncanny to art and aesthetics. Second, I disambiguate theoretical uses of ‘uncanny’ and establish the sense of the term that I am interested in—namely, an emotional state directed towards particular objects in the world which are characteristically eerie, creepy, and weird. Third, I look at Edgar Allan Poe’s ‘The Fall of the House of Usher’ (...) as a means of drawing out the conditions that I claim are essential to uncanny experiences, and then elaborate the terms of my proposed definition. Finally, I show how the definition accounts for two paradigmatic kinds of uncanny phenomena: cases of ‘uncanny resemblances’, which include twins, doppelgangers, and very lifelike representations of the human body; and unlikely coincidences of events.

Mechanistic explanations satisfy widely held norms of explanation: the ability to manipulate and answer counterfactual questions about the explanandum phenomenon. A currently debated issue is whether any nonmechanistic explanations can satisfy these explanatory norms. Weiskopf argues that the models of object recognition and categorization, JIM, SUSTAIN, and ALCOVE, are not mechanistic yet satisfy these norms of explanation. In this article I argue that these models are mechanism sketches. My argument applies recent research using model-based functional magnetic resonance imaging, a novel (...) neuroimaging method whose significance for current debates on psychological models and mechanistic explanation has yet to be explored.

Expressivists have a problem with negation. The problem is that they have not, to date, been able to explain why ‘murdering is wrong’ and ‘murdering is not wrong’ are inconsistent sentences. In this paper, I explain the nature of the problem, and why the best efforts of Gibbard, Dreier, and Horgan and Timmons don’t solve it. Then I show how to diagnose where the problem comes from, and consequently how it is possible for expressivists to solve it. Expressivists should accept (...) this solution, I argue, because it is demonstrably the only way of avoiding the problem, and because it generalizes. Once we see how to solve the negation problem, I show, it becomes easy to state a constructive, compositional expressivist semantics for a purely normative language with the expressive power of propositional logic, in which we can for the first time give explanatory, formally adequate expressivist accounts of logical inconsistency, logical entailment, and logical validity. As a corollary, I give what I take to be the first real expressivist explanation of why Geach’s original moral modus ponens argument is genuinely logically valid. This proves that the problem with expressivism cannot be that it can’t account for the logical properties of complex normative sentences. But it does not show that the same solution can work for a language with both normative and descriptive predicates, let alone that expressivists are able to deal with more complex linguistic constructions like tense, modals, or even quantifiers. In the final section, I show what kind of constraints the solution offered here would place expressivists under, in answering these further questions. (shrink)

This chapter explores a case study in contemporary fanaticism. We adopt Katsafanas’s conceptualization of fanaticism to make possible an in-depth discussion of and evaluation of a diffuse but important social movement — the anglophone manosphere. According to Katsafanas, fanatics are fruitfully understood as members of a group that adopts sacred values which they hold unconditionally to preserve their own psychic unity, and who feel that those values are threatened by those who do not accept them. The manosphere includes several social (...) movements, including incels, men’s rights activists, and men-going-their-own-way. We show that many members of these groups are well-characterized by Katsafanas’s theory of fanaticism, and that they have forged their fanatical group identity using tools that philosophers have tended to associate with more benign social movements and the task of “conceptual engineering.” Indeed, we think that manosphere groups have in many cases been more successful than more palatable liberationist movements, and that this case study in the dark side of conceptual engineering may be both sobering and informative.

This paper is about whether shifts in attention can alter what it is like to think. I begin by taking up the hypothesis that attention structures consciousness into a centre and a periphery, following Watzl's (2014; 2017) understanding of the distinction between the centre and periphery of the field of consciousness. Then I show that introspection leads to divided results about whether attention structures conscious thought into a centre and a periphery -- remarks by Martin (1997) and Phillips (2012) suggest (...) a negative answer, whereas remarks by Maher (1923) and Chudnoff (2013) suggest a positive answer. Lastly, I argue that there is behavioural evidence that lends weight to the 'yes' side of the introspective dispute. My argument makes use of Garavan's (1998) study of forming and maintaining two mental counts at once. (shrink)

This paper presents five studies on the development and validation of a scale of intellectual humility. This scale captures cognitive, affective, behavioral, and motivational components of the construct that have been identified by various philosophers in their conceptual analyses of intellectual humility. We find that intellectual humility has four core dimensions: Open-mindedness (versus Arrogance), Intellectual Modesty (versus Vanity), Corrigibility (versus Fragility), and Engagement (versus Boredom). These dimensions display adequate self-informant agreement, and adequate convergent, divergent, and discriminant validity. In particular, Open-mindedness (...) adds predictive power beyond the Big Six for an objective behavioral measure of intellectual humility, and Intellectual Modesty is uniquely related to Narcissism. We find that a similar factor structure emerges in Germanophone participants, giving initial evidence for the model’s cross-cultural generalizability. (shrink)

Freud’s famous essay “The ‘Uncanny’” is often poorly understood. In this paper, I clear up the popular misconception that Freud identifies all uncanny phenomena with the return of repressed infantile complexes by showing that he offers not one but two theories of the uncanny: “return of the repressed,” and another explanation that has to do with the apparent confirmation of “surmounted primitive beliefs.” Of the two, I argue that it is the latter, more often overlooked theory that faces fewer serious (...) objections and carries greater explanatory power in respect of the uncanny.

How should emotions figure in scientific practice? I begin by distinguishing three broad answers to this question, ranging from pessimistic to optimistic. Confirmation bias and motivated numeracy lead us to cast a jaundiced eye on the role of emotions in scientific inquiry. However, reflection on the essential motivating role of emotions in geniuses makes it less clear that science should be evacuated of emotion. I then draw on Friedrich Nietzsche’s perspectivism to articulate a twenty-first century epistemology of science that recognizes (...) the necessity of emotion to inquiry but aims to manage the biases that emotions can introduce. Twenty-first century perspectivism is both social and (temporally) distal, helping it to overcome a paradox of self-critical inquiry. (shrink)

Beliefs are concrete particulars containing ideas of properties and notions of things, which also are concrete. The claim made in a belief report is that the agent has a belief (i) whose content is a specific singular proposition, and (ii) which involves certain of the agent's notions and ideas in a certain way. No words in the report stand for the notions and ideas, so they are unarticulated constituents of the report's content (like the relevant place in "it's raining"). The (...) belief puzzles (Hesperus, Cicero, Pierre) involve reports about two different notions. So the analysis gets the puzzling truth values right. (shrink)

Expressivism’s central idea is that normative sentences bear the same relation to non-cognitive attitudes that ordinary descriptive sentences bear to beliefs: the expression relation. Allan Gibbard teIls us that “that words express judgments will be accepted by almost everyone” - the distinctive contribution of expressivism, his claim goes, is only a view about what kind of judgments words express. But not every account of the expression relation is equally suitable for the expressivist’s purposes. In fact, what I argue in this (...) paper, considering four possible accounts of expression, is that how suitable each account is for the expressivist’s purpose varies in proportion to how controversial it is. So Gibbard is wrong - if expression is to get expressivism off the ground, then it will be enormously controversial whether words do express judgments. And thus expressivism is committed to strong claims about the semantics of non-normative language. (shrink)

In a recent article, Dawn Wilson (2021) has argued against single-stage accounts of photography by arguing against the latent photographic images upon which those accounts depend. Concomitantly, she argues that the only viable account of photography is multi-stage. Unlike single-stage accounts, multi-stage accounts do not postulate the existence of photographic images of any kind prior to development. Rather, according to multi-stage accounts, photographs are produced from “photographic registers.” In this Discussion Piece, I defend single-stage accounts by arguing that Wilson’s rejection (...) of latent photographic images is premised on an implausible view of what a latent photographic image is. Given a reasonable interpretation, the latent images described in single-stage accounts just are the photographic registers described in multi-stage accounts. (shrink)

This is a book about the metaphysics of perception and discusses touch, audition, and vision. Though primarily concerned with the nature of perception, it draws heavily from the history of philosophy of perception, and connects the concerns of analytical and continental philosophers.

Preregistration has been proposed as a useful method for making a publicly verifiable distinction between confirmatory hypothesis tests, which involve planned tests of ante hoc hypotheses, and exploratory hypothesis tests, which involve unplanned tests of post hoc hypotheses. This distinction is thought to be important because it has been proposed that confirmatory hypothesis tests provide more compelling results (less uncertain, less tentative, less open to bias) than exploratory hypothesis tests. In this article, we challenge this proposition and argue that there (...) are several advantages of exploratory hypothesis tests that can make their results more compelling than those of confirmatory hypothesis tests. We also consider some potential disadvantages of exploratory hypothesis tests and conclude that their advantages can outweigh the disadvantages. We conclude that exploratory hypothesis tests avoid researcher commitment and researcher prophecy biases, reduce the probability of data fraud, are more appropriate in the context of unplanned deviations, facilitate inference to the best explanation, and allow peer reviewers to make additional contributions at the data analysis stage. In contrast, confirmatory hypothesis tests may lead to an inappropriate level of confidence in research conclusions, less appropriate analyses in the context of unplanned deviations, and greater bias and errors in theoretical inferences.

According to Nietzsche, drives are the ultimate constituents of virtues and vices. I argue that Nietzsche identifies two blueprints for character construction: a slavish, interpersonal blueprint, and a masterly, reflexive blueprint. When the interpersonal blueprint is implemented, a person becomes what he is called: his drives are shaped by the traits ascribed to him so that he becomes more like the sort of person he’s taken to be. When the reflexive blueprint is implemented, a person becomes more like the sort (...) of person she calls herself: her drives are shaped by the traits she ascribes to herself in a community of peers. The reflexive blueprint shares some surprising similarities with the interpersonal blueprint. I conclude with an account of Nietzschean summoning, which occurs when one person praises a generic type to an audience, implicitly inviting them to identify with that type and thereby to become more like it.

This reply is a refutation of Santiago Vrech’s article “The End of the Case? A Metaphilosophical Critique of Thought Experiments” (2022) which argues that thought experiments used in argumentation cannot hold in All Possible Worlds (APW) modality, and thus should end. Cases are used to justify or refute a philosophical theory, but should not have the power to refute an entire theory, especially ad infinitum. Significant variations in intuitions, he argues, invalidate cases and are not proven. I argue some variation (...) is acceptable and expected, and his bar of criteria is too high—APW validity is unnecessary. Vrech’s three arguments are faulty and/ or too weak, and his thought experiment is of questionable value. Experimental and armchair philosophy (or philosophers) are misnomers, misleading and false dichotomy. (shrink)

This book investigates what change is, according to Aristotle, and how it affects his conception of being. Mark Sentesy argues that change leads Aristotle to develop first-order metaphysical concepts such as matter, potency, actuality, sources of being, and the teleology of emerging things. He shows that Aristotle’s distinctive ontological claim—that being is inescapably diverse in kind—is anchored in his argument for the existence of change. -/- Aristotle may be the only thinker to have given a noncircular definition of change. (...) When he gave this definition, arguing that change is real was a losing proposition. To show that it exists, he had to rework the way philosophers understood reality. His groundbreaking analysis of change has long been interpreted through a Platonist lens, however, in which being is conceived as unchanging. Offering a comprehensive reexamination of the relationship between change and being in Aristotle, Sentesy makes an important contribution to scholarship on Aristotle, ancient philosophy, the history and philosophy of science, and metaphysics.

This paper examines how professionals (N = 32) working on artificial intelligence (AI) view structural AI ethics challenges like injustices and inequalities beyond individual agents' direct intention and control. This paper answers the research question: What are professionals’ perceptions of the structural challenges of AI (in the agri-food sector)? This empirical paper shows that it is essential to broaden the scope of ethics of AI beyond micro- and meso-levels. While ethics guidelines and AI ethics often focus on the responsibility of (...) designers and the competencies and skills of designers to take this responsibility, our results show that many structural challenges are beyond their reach. This result means that while ethics guidelines and AI ethics frameworks are helpful, there is a risk that they overlook more complicated, nuanced, and intersected structural challenges. In addition, it highlights the need to include diverse stakeholders, such as quadruple helix (QH) participants, in discussions around AI ethics rather than solely focusing on the obligations of AI developers and companies. Overall, this paper demonstrates that addressing structural challenges in AI is challenging and requires an approach that considers four requirements: (1) multi-level, (2) multi-faceted, (3) interdisciplinary, and (4) polycentric governance.

The last two decades have stood witness to a quiet revolution in epistemology. We used to think of ethics and epistemology as quite distinct areas of inquiry – ethics concerned with action, and epistemology concerned with belief. While ethics is the domain of values, epistemology is the domain of facts – the facts that we must get right, and get right first, in order to know how to pursue our values in ethics. The only competing values in epistemology, we were (...) taught, were those of acquiring truth and avoiding error. But proponents of the revolution have pushed us to find values in the stronghold of truth. They have argued that rationality, justification, and even knowledge can depend on what is practically or even morally at stake, so that we can't do epistemology without thinking about values. And some have gone further, arguing that ethics is not just about action, after all, but also includes distinctively moral, and not just epistemological, questions about what to believe. The revolution in our understanding of the relationship between ethics and epistemology is well underway. -/- Yet as in all revolutionary movements, there comes a moment when the revolutionaries must decide amongst themselves whether what they seek is reform or annihilation of the received world order. The reformists seek calculated interventions in the order of things. But the radicals want to go farther. They believe that more of the old must be thrown out, before the new can be ushered in. This is a chaotic period, when the revolution can yet be lost, if and as the alternative begins to look like total anarchy. And many possible visions of the future remain in play. This paper is a contribution toward working through these issues amongst the revolutionaries in epistemology. Let there be no surprises in this paper: I am of a reformist mindset, and the aim of this paper is to hold the line on cautious, calculated intervention, even in the pursuit of bold results.

Mark Eli Kalderon presents an original study of perception, taking as its starting point a puzzle in Empedocles' theory of vision: if perception is a mode of material assimilation, how can we perceive colors at a distance? Kalderon argues that the theory of perception offered by Aristotle in answer to the puzzle is both attractive and defensible.

This book is the first comprehensive study of the meaning and measure of enforceability. While we have long debated what restraints should govern the conduct of our social life, we have paid relatively little attention to the question of what it means to make a restraint enforceable. Focusing on the enforceability of legal rights but also addressing the enforceability of moral rights and social conventions, Mark Reiff explains how we use punishment and compensation to make restraints operative in the (...) world. After describing the various means by which restraints may be enforced, Reiff explains how the sufficiency of enforcement can be measured, and he presents a unified theory of deterrence, retribution, and compensation that shows how these aspects of enforceability are interconnected. Reiff then applies his theory of enforceability to illuminate a variety of real-world problem situations. (shrink)

In Beyond Good and Evil, Nietzsche demands that “psychology shall be<br>recognized again as the queen of the sciences.” While one might cast a dubious glance at the “again,” many of Nietzsche’s insights were indeed psychological, and many of his arguments invoke psychological premises. In Genealogy, he criticizes the “English psychologists” for the “inherent psychological absurdity” of their theory of the origin of good and bad, pointing out the implausibility of the claim that the utility of unegoistic<br>actions would be forgotten. Tabling (...) whether this criticism is valid, we see Nietzsche’s methodological naturalism here: moral claims should be grounded in empirical psychological claims. Later in Genealogy, Nietzsche advances his own naturalistic account of the origins of good, bad, and evil.<br>Three cheers for methodological naturalism, but it was not Nietzsche’s innovation, and he did not pioneer its application to morality. The list of moral naturalists who appealed to psychology arguably includes Aristotle, Descartes, Spinoza, Bentham, and Mill, among many others. If Nietzsche’s naturalism is to be worth the candle of contemporary scholarship, it must involve more than the methodological naturalism that predated him by centuries and to which he made no serious contribution. Nietzsche’s key contribution to naturalism is not his adherence to its methodology, but his discovery of certain psychological facts. In particular, he realized that mental states are not ordinary dyadic relations between a subject and an intentional content. Nietzsche discovered the tenacity of intentional states: when an intentional state loses its object (because the subject realizes the object does not exist, because the object is forbidden, or because of something else), a new object replaces the original; the state does not disappear entirely. As Nietzsche puts it Genealogy, “Man would rather will the void than be void of will.” Nietzsche relies on the tenacity thesis in his explanation of the origin of bad conscience: “All instincts that do not discharge themselves outwardly turn inward […. They turn] against [their] possessors.” When hostility towards others becomes impossible, hostility does not disappear; instead, its object is replaced. (shrink)

Negative facts get a bad press. One reason for this is that it is not clear what negative facts are. We provide a theory of negative facts on which they are no stranger than positive atomic facts. We show that none of the usual arguments hold water against this account. Negative facts exist in the usual sense of existence and conform to an acceptable Eleatic principle. Furthermore, there are good reasons to want them around, including their roles in causation, chance-making (...) and truth-making, and in constituting holes and edges. (shrink)

Philosophers have come to distinguish between ‘right’ and ‘wrong’ kinds of reasons for belief, intention, and other attitudes. Several theories about the nature of this distinction have been offered, by far the most prevalent of which is the idea that it is, at bottom, the distinction between what are known as ‘object-given’ and ‘state-given’ reasons. This paper argues that the object-given/state-given theory vastly overgeneralizes on a small set of data points, and in particular that any adequate account of the distinction (...) between the ‘right’ and ‘wrong’ kinds of reason must allow state-given reasons to be of the right kind. The paper has three main goals, corresponding to its three main parts. In part 1 I set up the problem by introducing the right-kind/wrong-kind distinction, the object-given/state-given distinction, and the object-given/state-given theory, according to which the former distinction simply amounts to the latter. Part 2 presents the main argument of the paper: I argue against the object-given/state-given theory by showing that all of the earmarks of the ‘right’ and ‘wrong’ kinds of reason apply to reasons not to intend and not to believe, but that these cases can’t be captured by the object-given/state-given theory. Finally, in part 3 I use these arguments to motivate and explore a more general hypothesis about the rightkind/wrong-kind distinction, and explore some of the consequences of rejecting the object-given/stategiven theory.

Fitting Attitudes accounts of value analogize or equate being good with being desirable, on the premise that ‘desirable’ means not, ‘able to be desired’, as Mill has been accused of mistakenly assuming, but ‘ought to be desired’, or something similar. The appeal of this idea is visible in the critical reaction to Mill, which generally goes along with his equation of ‘good’ with ‘desirable’ and only balks at the second step, and it crosses broad boundaries in terms of philosophers’ other (...) commitments. For example, Fitting Attitudes accounts play a central role both in T.M. Scanlon’s [1998] case against teleology, and in Michael Smith [2003], [unpublished] and Doug Portmore’s [2007] cases for it. And of course they have a long and distinguished history. (shrink)

Remembering that there’s a difference between intellectual and perceptual attention can help us avoid miscommunication due to meaning different things by the same terms, which has been a particular problem during the last hundred years or so of the study of attention. I demonstrate this through analyzing in depth one such miscommunication that occurred in a philosophical criticism of the influential psychological text, Inattentional Blindness. But after making the distinction between perceptual attention and intellectual attention, and after making an effort (...) to keep this distinction in mind, we are still faced with the problem of specifying what makes intellectual attention distinct from perceptual attention. In the second half of this article, I discuss the range of proposals about how to understand intellectual attention that are present in the literature, and the problems with them. I do this with the aim of stimulating further discussion about how best to conceptualize intellectual attention, although I do not settle that further question within this paper. (shrink)

Most philosophers find it puzzling how beliefs could wrong, and this leads them to conclude that they do not. So there is much philosophical work to be done in sorting out whether I am right to say that they do, as well as how this could be so. But in this paper I will take for granted that beliefs can wrong, and ask instead when beliefs wrong. My answer will be that beliefs wrong when they falsely diminish. This answer has (...) three parts: that beliefs wrong only when they are false, that beliefs wrong only when they diminish, and that false diminishment is sufficient for wronging. I will seek to elaborate on and defend all three of these claims, but it is the first to which I will give the most attention. (shrink)

Interpreters have noticed that Nietzsche, in addition to sometimes being uproariously funny, reflects more on laughter and having a sense of humor than almost any other philosopher. Several scholars have further noticed that Nietzschean laughter sometimes seems to have an epistemic function. In this chapter, I assume that Nietzsche is a pluralist about the functions of humor and laughter, and seek to establish the uses he finds for them. I offer an interpretation according to which he tactically uses humor and (...) laughter for epistemic purposes. His epistemic aims include enabling inquiry (when faith and reverence might have forbidden it), achieving knowledge (for himself or for his reader), and abandoning error (again for himself or for his reader). Humor supports these goals by inducing contempt and the laughter that expresses (and sometimes also conjures) it. (shrink)

Several authors have recently endorsed the thesis that there is what has been called pragmatic encroachment on knowledge—in other words, that two people who are in the same situation with respect to truth-related factors may differ in whether they know something, due to a difference in their practical circumstances. This paper aims not to defend this thesis, but to explore how it could be true. What I aim to do, is to show how practical factors could play a role in (...) defeating knowledge by defeating epistemic rationality—the very kind of rationality that is entailed by knowledge, and in which Pascalian considerations do not play any role—even though epistemic rationality consists in having adequate evidence.

Real-world agents do not know all consequences of what they know. But we are reluctant to say that a rational agent can fail to know some trivial consequence of what she knows. Since every consequence of what she knows can be reached via chains of trivial cot be dismissed easily, as some have attempted to do. Rather, a solution must give adequate weight to the normative requirements on rational agents’ epistemic states, without treating those agents as mathematically ideal reasoners. I’ll (...) argue that agents can fail to know trivial consequences of what they know, but never determinately. Such cases are epistemic oversights on behalf of the agent in question, and the facts about epistemic oversights are always indeterminate facts. As a result, we are never in a position to assert that such-and-such constitutes an epistemic oversight for agent i (for we may rationally assert only determinate truths). I then develop formal epistemic models according to which epistemic accessibility relations are vague. Given these models, we can show that epistemic oversights always concern indeterminate cases of knowledge. (shrink)

Keepsakes are nostalgic objects par excellence. We value keepsakes because they prompt nostalgic memories of the past. But perhaps more importantly, we also value them because they afford a feeling of contact with that which they remind us of. Drawing on work in philosophy and psychology, this chapter aims to give an account of the nature and value of keepsakes as nostalgic objects. Keepsakes, it argues, are objects that bear a material continuity with some person, event, or place from one’s (...) past to which one has a personal attachment. To understand the distinctive experiential value of keepsakes as nostalgic objects, however, the chapter argues that we need to invoke the imagination. Keepsakes manifest the presence of the past by prompting one to imaginatively project what a keepsake is historically connected with onto the object as one experiences it in the present. (shrink)

What is it to have a reason? According to one common idea, the "Factoring Account", you have a reason to do A when there is a reason for you to do A which you have--which is somehow in your possession or grasp. In this paper, I argue that this common idea is false. But though my arguments are based on the practical case, the implications of this are likely to be greatest in epistemology: for the pitfalls we fall into when (...) trying to defend the Factoring Account reflect very well the major developments in empiricist epistemology during the 20th century. I conjecture that this is because epistemologists have been--wrongly--wedded to the Factoring Account about evidence, which I conjecture is a certain kind of reason to believe. (shrink)

Differently illuminated, things in one sense look different, but in another sense look the same.

YouTube has been implicated in the transformation of users into extremists and conspiracy theorists. The alleged mechanism for this radicalizing process is YouTube’s recommender system, which is optimized to amplify and promote clips that users are likely to watch through to the end. YouTube optimizes for watch-through for economic reasons: people who watch a video through to the end are likely to then watch the next recommended video as well, which means that more advertisements can be served to them. This (...) is a seemingly innocuous design choice, but it has a troubling side-effect. Critics of YouTube have alleged that the recommender system tends to recommend extremist content and conspiracy theories, as such videos are especially likely to capture and keep users’ attention. To date, the problem of radicalization via the YouTube recommender system has been a matter of speculation. The current study represents the first systematic, pre-registered attempt to establish whether and to what extent the recommender system tends to promote such content. We begin by contextualizing our study in the framework of technological seduction. Next, we explain our methodology. After that, we present our results, which are consistent with the radicalization hypothesis. Finally, we discuss our findings, as well as directions for future research and recommendations for users, industry, and policy-makers. (shrink)
