The recent emergence of machine-manipulated media raises an important societal question: How can we know whether a video that we watch is real or fake? In two online studies with 15,016 participants, we present authentic videos and deepfakes and ask participants to identify which is which. We compare the performance of ordinary human observers with the leading computer vision deepfake detection model and find them similarly accurate, while making different kinds of mistakes. Together, participants with access to the model’s prediction (...) are more accurate than either alone, but inaccurate model predictions often decrease participants’ accuracy. To probe the relative strengths and weaknesses of humans and machines as detectors of deepfakes, we examine human and machine performance across video-level features, and we evaluate the impact of preregistered randomized interventions on deepfake detection. We find that manipulations designed to disrupt visual processing of faces hinder human participants’ performance while mostly not affecting the model’s performance, suggesting a role for specialized cognitive capacities in explaining human deepfake detection performance. -/- .

Science begins with mystery. What causes lightning? How did this mold stop bacterial growth? Why do we age? Arguably, the two greatest mysteries are the cosmos and consciousness—the vast world out there and the vibrant world within. Scientists captivated by one can be called to study the other, seduced by the thought that these mysteries are connected. Science writer George Musser’s book Putting Ourselves Back in the Equation reviews their progress: Can physics unlock the mystery of consciousness? Does consciousness underlie (...) fundamental physics? (shrink)

When a circular coin is rotated in depth, is there any sense in which it comes to resemble an ellipse? While this question is at the center of a rich and divided philosophical tradition (with some scholars answering affirmatively and some negatively), Morales et al. (2020, 2021) took an empirical approach, reporting 10 experiments whose results favor such perspectival similarity. Recently, Burge and Burge (2022) offered a vigorous critique of this work, objecting to its approach and conclusions on both philosophical (...) and empirical grounds. Here, we answer these objections on both fronts. We show that Burge and Burge’s critique rests on misunderstandings of Morales et al.’s claims; of the relation between the data and conclusions; and of the philosophical context in which the work appears. Specifically, Burge and Burge attribute to us a much stronger (and stranger) view than we hold, involving the introduction of “a new entity” located “in some intermediate position(s) between the distal shape and the retinal image.” We do not hold this view. Indeed, once properly understood, most of Burge and Burge’s objections favor Morales et al.’s claims rather than oppose them. Finally, we discuss several questions that remain unanswered, and reflect on a productive path forward on these issues of foundational scientific and philosophical interest. (shrink)

At the centenary of Frank H. Knight’s Risk, Uncertainty, and Profit, we explore the continuing relevance of Knightian uncertainty to the theory and practice of entrepreneurship. There are three challenges facing such assessment. First, RUP is complex and difficult to interpret. The key but neglected element of RUP is that Knight’s account is not solely about risk and uncertainty as states of nature, but about how an agent’s beliefs about uncertain outcomes and confidence in those beliefs guide their choices. Second, (...) RUP is Knight’s only effort in this area. His subsequent career led elsewhere, so he did not engage with subsequent interpretations of this work. Third, much of the current literature emphasizes that decisions must be different under the two states of nature with a consequent misunderstanding of entrepreneurial agency. This paper addresses each challenge in sequence. First, we explicate Knight’s approach and explain why that approach is murky. Second, as a complement to Knight’s interpretation, we examine Frank P. Ramsey’s approach to subjective probabilities to help clarify Knight’s murky approach. What links Knight and Ramsey is a shared pragmatism about entrepreneurial agency under uncertainty that depends upon the beliefs about, and confidence in, their judgments of possible outcomes. This Knight-Ramsey approach does not require actor’s behaviors to be determined by the class of uncertain environment they face. We focus on the response by the entrepreneur to the existence of uncertainty in all its forms. We argue that this reductive account provides a foundation to examine common problems in management, including managerial hubris, the interaction between entrepreneurs and venture capitalists, and the need for experimentation in advance of new product and venture launches. Third, we critique current literature that favors epistemic purism about the ontology of risk and uncertainty and ignores Knight-Ramsey pragmatism in meeting uncertainty, such as using formal and informal institutions for uncertainty mitigation. Our account locates Frank Knight’s subtleties in entrepreneurial behavior firmly in the literature on entrepreneurial agency a century later. (shrink)

Arguably the most foundational principle in perception research is that our experience of the world goes beyond the retinal image; we perceive the distal environment itself, not the proximal stimulation it causes. Shape may be the paradigm case of such “unconscious inference”: When a coin is rotated in depth, we infer the circular object it truly is, discarding the perspectival ellipse projected on our eyes. But is this really the fate of such perspectival shapes? Or does a tilted coin retain (...) an elliptical appearance even when we know it’s circular? This question has generated heated debate from Locke and Hume to the present; but whereas extant arguments rely primarily on introspection, this problem is also open to empirical test. If tilted coins bear a representational similarity to elliptical objects, then a circular coin should, when rotated, impair search for a distal ellipse. Here, nine experiments demonstrate that this is so, suggesting that perspectival shapes persist in the mind far longer than traditionally assumed. Subjects saw search arrays of three-dimensional “coins,” and simply had to locate a distally elliptical coin. Surprisingly, rotated circular coins slowed search for elliptical targets, even when subjects clearly knew the rotated coins were circular. This pattern arose with static and dynamic cues, couldn’t be explained by strategic responding or unfamiliarity, generalized across shape classes, and occurred even with sustained viewing. Finally, these effects extended beyond artificial displays to real-world objects viewed in naturalistic, full-cue conditions. We conclude that objects have a remarkably persistent dual character: their objective shape “out there,” and their perspectival shape “from here.”. (shrink)

Van Fraassen's Judy Benjamin problem asks how one ought to update one's credence in A upon receiving evidence of the sort ``A may or may not obtain, but B is k times likelier than C'', where {A,B,C} is a partition. Van Fraassen's solution, in the limiting case of increasing k, recommends a posterior converging to the probability of A conditional on A union B, where P is one's prior probability function. Grove and Halpern, and more recently Douven and Romeijn, have (...) argued that one ought to leave credence in A unchanged, i.e. fixed at P(A). We argue that while the former approach is superior, it brings about a Reflection violation due in part to neglect of a ``regression to the mean'' phenomenon, whereby when C is eliminated by random evidence that leaves A and B alive, the ratio P(A):P(B) ought to drift in the direction of 1:1.

Perception is our primary means of accessing the external world. What is the nature of this core mental process? Although this question is at the center of scientific research on perception, it has also long been explored by philosophers, who ask fundamental questions about our capacity to perceive: Do our different senses represent the world in commensurable ways? How much of our environment can we be aware of at one time? Which aspects of perception are ‘objective’, and which ‘subjective’? What (...) properties count as perceptual in the first place? Although these parallel research programs typically proceed independently in contemporary scholarship, previous eras recognized more active collaboration and interaction across philosophical and scientific approaches to perception. Here, we review an emerging research focus that has begun to reunite these approaches, by putting several long-standing philosophical questions to empirical test. Unlike more general sources of philosophical inspiration, the work described here draws a direct line from a prominent philosophical conjecture or thought experiment about perception to a key test of that question in the laboratory—such that the relevant experimental work would not (and even could not) have proceeded as it did without the preceding philosophical discussion. Finally, we explore themes arising from these successful interactions, and point to further philosophical questions that might be amenable to empirical approaches. (shrink)

Many actions have instrumental aims, in which we move our bodies to achieve a physical outcome in the environment. However, we also perform actions with epistemic aims, in which we move our bodies to acquire information and learn about the world. A large literature on action recognition investigates how observers represent and understand the former class of actions; but what about the latter class? Can one person tell, just by observing another person’s movements, what they are trying to learn? Here, (...) 5 experiments explore epistemic action understanding. We filmed volunteers playing a ‘physics game’ consisting of two rounds: Players shook an opaque box and attempted to determine (i) the number of objects hidden inside, or (ii) the shape of the objects inside. Then, independent subjects watched these videos and were asked to determine which videos came from which round: Who was shaking for number and who was shaking for shape? Across several variations, observers successfully determined what an actor was trying to learn, based only on their actions (i.e., how they shook the box)—even when the box’s contents were identical across rounds. These results demonstrate that humans can infer epistemic intent from physical behaviors, adding a new dimension to research on action understanding. (shrink)

Michael Huemer argues, on statistical grounds, that ``existence is evidence for immortality". On reasoning derived from the anthropic principle, however, mere existence cannot be evidence against any non-indexical, ``eternal'' hypothesis that predicts observers. This note attempts to advertise the much-flouted anthropic principle's virtues and workings in a new way, namely by calling attention to the fact that it is the primary intension of one's indexically-described evidence that best characterizes one's epistemic position.

A critical reading of Sarah Moss's "Probabilistic Knowledge".

Drawing on work from Marina Sbisà’s “Ideology and the Persuasive Use of Presupposition” (1999), Rae Langton has developed a powerful account of the subtle mechanisms through which hate speech and propaganda spread. However, this model has a serious limitation: it focuses too strongly on individual speech acts isolated from their wider context, rendering its applicability to a broader range of cases suspect. In this chapter, I consider the limits of presupposition accommodation to clarify the audience’s role in helping hate speakers, (...) and claim the necessary mechanisms are much more active and social than Langton suggests, with effects not capturable in the analysis of isolated speech acts. I revisit Sbisà’s work on presupposition and develop an alternative model that (1) improves upon the Langtonian model for explaining the power of hate propaganda, and (2) is more in line with Sbisà’s original approach to ideology and the normative aspects of presupposition.

This chapter examines what protest is from the point of view of pragmatics, and how it relates to propaganda—specifically what Jason Stanley calls ‘positive propaganda.’ It analyzes the phrase “Black Lives Matter,” taking it to be a political speech act that offers a unique route to understanding of the pragmatics of protest. From this, it considers the moral-epistemological function of protest, and develops an account of the authority that protest, as a speech act, both calls upon and makes explicit. It (...) then argues that, rather than simply its effects, it is protest’s distinct pragmatic features—that is, its entitlement conditions, and the uptake it aim at—that best capture its important moral, political, and epistemic elements. It therefore rejects the idea that protests are paradigmatic examples of ‘positive propaganda,’ because the propaganda model cannot capture protests’ function of foregrounding the socially located moral authority of the protestor.

Auditory perception is traditionally conceived as the perception of sounds — a friend’s voice, a clap of thunder, a minor chord. However, daily life also seems to present us with experiences characterized by the absence of sound — a moment of silence, a gap between thunderclaps, the hush after a musical performance. In these cases, do we positively hear silence? Or do we just fail to hear, and merely judge or infer that it is silent? This longstanding question remains controversial (...) in both the philosophy and science of perception, with prominent theories holding that sounds are the only objects of auditory experience and thus that our encounter with silence is cognitive, not perceptual. However, this debate has largely remained theoretical, without a key empirical test. Here, we introduce a novel empirical approach, presenting experimental evidence that silence can be genuinely perceived (not just cognitively inferred). We ask whether silences can ‘substitute’ for sounds in event-based auditory illusions — empirical signatures of auditory event representation in which auditory events distort perceived duration. Seven experiments introduce three new ‘silence illusions’ — the one-silence-is-more illusion, silence-based warping, and the oddball-silence illusion — each adapted from a prominent perceptual illusion previously thought to arise only from sounds. Subjects were immersed in ambient noise interrupted by silences structurally identical to the sounds in the original illusions. In all cases, silences elicited temporal distortions perfectly analogous to the illusions produced by sounds. Our results suggest that silence is truly heard, not merely inferred, introducing a general approach for studying absence perception. (shrink)

How a group G can know that p has been the subject of much investigation in social epistemology in recent years. This paper clarifies and defends a form of non-supervenient, non-summative group knowledge: G can know that p even if none of the members of G knows that p, and whether or not G knows that p does not locally supervene on the mental states of the members of G. Instead, we argue that what is central to G knowing that (...) p is whether G has an epistemic structure that is functioning appropriately in accord with the action-related purposes of the group, and this structure may include non-agential elements such as devices that retain or process information. We argue that recent objections to non-summative group knowledge given by Jennifer Lackey do not in fact succeed in undermining the view, but do help to clarify the nature of non-summative group knowledge. The main upshot of our response to Lackey’s objections is that groups put their knowledge into action in ways that often differ from how individuals do so, and social epistemologists should be careful to notice these differences, especially insofar as groups often structure themselves by employing various epistemically-relevant devices.

Jesper Kallestrup has provided an insightful response to our paper, “Epistemic Structure in Non-Summative Social Knowledge”. Kallestrup identifies some important issues pertaining to our non-summative, non-supervenient account of group knowledge which we did not address in our original paper. Here, we develop our view further in light of Kallestrup’s helpful reply.

Quilty-Dunn et al.'s wide-ranging defense of the Language of Thought Hypothesis (LoTH) argues that vision traffics in abstract, structured representational formats. We agree: Vision, like language, is compositional – just as words compose into phrases, many visual representations contain discrete constituents that combine in systematic ways. Here, we amass evidence extending this proposal, and explore its implications for how vision interfaces with the rest of the mind.

When a piece of fruit is in a bowl, and the bowl is on a table, we appreciate not only the individual objects and their features, but also the relations containment and support, which abstract away from the particular objects involved. Independent representation of roles (e.g., containers vs. supporters) and “fillers” of those roles (e.g., bowls vs. cups, tables vs. chairs) is a core principle of language and higherlevel reasoning. But does such role-filler independence also arise in automatic visual processing? (...) Here, we show that it does, by exploring a surprising error that such independence can produce. In four experiments, participants saw a stream of images containing different objects arranged in forcedynamic relations — e.g., a phone contained in a basket, a marker resting on a garbage can, or a knife sitting in a cup. Participants had to respond to a single target image (e.g., a phone in a basket) within a stream of distractors presented under time constraints. Surprisingly, even though participants completed this task quickly and accurately, they false-alarmed more often to images matching the target’s relational category than to those that did not — even when those images involved completely different objects. In other words, participants searching for a phone in a basket were more likely to mistakenly respond to a knife in a cup than to a marker on a garbage can. Follow-up experiments ruled out strategic responses and also controlled for various confounding image features. We suggest that visual processing represents relations abstractly, in ways that separate roles from fillers. (shrink)

In August of 2000, Firestone executives initiated the second largest tire recall in U.S. history. Many of the recalled tires had been installed as original factory equipment on the popular Ford Explorer SUVs. At the time of the recall, the tires and vehicles had been linked to numerous accidents and deaths, most of which occurred when tire blowouts resulted in vehicle rollovers. While Firestones role in this case has been widely acknowledged, Ford executives have managed to deflect much of (...) the attention away from themselves, mainly by claiming that the Firestone tires were not its product, and therefore not its responsibility. In this paper, we examine the extent to which Ford can be held morally responsible for the incidents at issue. In so doing, we develop an approach for determining when an item is a product in its own right, as opposed to a component of another product. We argue that such an analysis not only provides a better understanding of this case, but also more properly accounts for the extent to which evolutions in technology and business relationships can affect issues of moral responsibility in business contexts.

When viewing a circular coin rotated in depth, it fills an elliptical region of the distal scene. For some, this appears to generate a two-fold experience, in which one sees the coin as simultaneously circular (in light of its 3D shape) and elliptical (in light of its 2D ‘perspectival shape’ or ‘p-shape’). An energetic philosophical debate asks whether the latter p-shapes are genuinely presented in perceptual experience (as ‘perspectivalists’ argue) or if, instead, this appearance is somehow derived or inferred from (...) experience (as ‘anti-perspectivalists’ argue). This debate, however, has largely turned on introspection. In a recent study, Morales, Bax, and Firestone (2020) aim to provide the first empirical test of this question. They asked subjects to find an elliptical coin seen face-on from a search array that also included a circular coin seen either face-on or at an angle. They found that subjects reacted more slowly when the distracting circle was seen at an angle, such that it’s p-shape matched that of the target ellipse. From this, they concluded that the similar p-shape between the ellipse and circle constituted a phenomenal similarity between the two, and thus that perspectivalism is true. We show that these results can also be explained by pre-attentive guidance by unconscious representations (in what follows, just “unconscious pre-attentive guidance”) and that this explanation is at least as plausible as one from phenomenal similarity. Thus, we conclude that the experiment does not support perspectivalism over anti-perspectivalism. (shrink)

This article explores the possibility that John Dewey’s silence on the matter of which democratic means are needed to achieve democratic ends, while confusing, makes greater sense if we appreciate the notion of political technology from an anthropological perspective. Michael Eldridge relates the exchange between John Herman Randall, Jr., and Dewey in which Dewey concedes “that I have done little or nothing in this direction [of outlining what constitutes adequate political technology, but that] does not detract from my recognition (...) that in the concrete the invention of such a technology is the heart of the problem of intelligent action in political matters.” Dewey’s concession could be interpreted as an admission that he was unqualified to identify political machinery or institutions suitable for realizing his vision of democracy as a way of life. Not being able to specify adequate means to achieve lofty democratic ends is not problematic, though, if we appreciate the roots of Dewey’s work (especially Human Nature and Conduct) in the anthropological writings of Immanuel Kant and Franz Boas. For then experience reflects a myriad of social and cultural conditions such that specifying explicit means to structure that experience risks stymieing the organic development of political practice. When pressured to operationalize political technology, he chose the appropriately open-ended and, at times, frustratingly vague means of education and growth. In short, Dewey did not want his ambitious democratic vision to outstrip the possibilities of practice, so he left the task of specifying exact political technology (or which democratic means are best suited to achieve democratic ends) unfinished.

Ectogenesis, or “artificial womb technology,” has been heralded by some, such as prominent feminist Shulamith Firestone, as a way to liberate women. In this chapter, we challenge this view by offering an alternative analysis of the technology as relying upon and perpetuating a problematic model of pregnancy which, rather than liberating women, serves to devalue them. We look to metaphysics as the abstract study of reality to elucidate how the entities in a pregnancy are related to one another. We (...) consider two models of the metaphysics of pregnancy: (1) the Parthood Model, whereby the fetus is a part of what/who gestates it; and (2) and the Fetal Container Model, whereby the gestator is a container for the fetus. We suggest that under the assumption of the Fetal Container Model, we are more likely to think that any container will suffice for gestation, even an artificial one. In contrast, under the assumption of the Parthood Model, we are less likely to treat the gestator as interchangeable or replaceable, given the parthood relationship between gestator and fetus. This chapter argues that ectogenesis is conceptually linked to the Fetal Container Model and advocates a more cautious approach in promoting ectogenesis as a tool for women’s liberation. (shrink)

Sgarbi just shows that in the century before Locke’s Essay Concerning Human Understanding many writers mentioned induction and many claimed that knowledge must rely somehow on sense experience. An attempt to revive Randall’s thesis needs more than that.

In this paper, we introduce and defend the recurrent model for understanding bodily spatial phenomenology. While Longo, Azañón and Haggard (2010) propose a bottom-up model, Bermúdez (2017) emphasizes the top-down aspect of the information processing loop. We argue that both are only half of the story. Section 1 intro- duces what the issues are. Section 2 starts by explaining why the top- down, descending direction is necessary with the illustration from the ‘body-based tactile rescaling’ paradigm (de Vignemont, Ehrsson and Haggard, (...) 2005). It then argues that the bottom-up, ascending direction is also necessary, and substantiates this view with recent research on skin space and tactile field (Haggard et al., 2017). Section 3 discusses the model’s application to body ownership and bodily self-representation. Implications also extend to topics such as sense modality individuation (Macpherson, 2011), the constancy- based view of perception (Burge, 2010), and the perception/cognition divide (Firestone and Scholl, 2016).

Zenon Pylyshyn argues that cognitively driven attentional effects do not amount to cognitive penetration of early vision because such effects occur either before or after early vision. Critics object that in fact such effects occur at all levels of perceptual processing. We argue that Pylyshyn’s claim is correct—but not for the reason he emphasizes. Even if his critics are correct that attentional effects are not external to early vision, these effects do not satisfy Pylyshyn’s requirements that the effects be direct (...) and exhibit semantic coherence. In addition, we distinguish our defense from those found in recent work by Raftopoulos and by Firestone and Scholl, argue that attention should not be assimilated to expectation, and discuss alternative characterizations of cognitive penetrability, advocating a kind of pluralism.

1. The most original discovery in Beauvoir’s book is one more Columbus’s egg, namely that it is far from evident that a woman is a woman. That is, she discovers that a woman is the result of a process that made so that she is like she is. The paper discusses two aspects of the so-to-say ‘ideology’ inspiring the work. The first is its ideology in the proper, Marxian sense. My claim is that the work still pays a heavy price (...) to the dominating ideology. It leaves still too much unquestionedof what was assumed at the time to be obvious, necessary, and unchanging. This ballast depends firstly on the inherited prevailing climate of opinion, corresponding to a situation of alienation, producing two distorted views of the male and female gender. On the other hand, it depends on an unquestioned legacy from the modern episteme (in Foucault’s sense of the word) carrying presupposed Cartesian dualism. The other side of the work’s ideology, that is, the positive program presented or better the utopia it formulates is less innovative than it could be, In a few passages, where she seems to make use of suggestions from Merleau-Ponty, she points at a view where the bodily and emotional dimension is rescued from its negation in the male-dominated Capitalist society. Still, these suggestions are forgotten in the bulk of the work. -/- 2. The making of a philosophical work does not depend just on the kind of philosophical influences behind it. A book is also the product of an author with a story living in one society at a given time of social history. In this case, the book was written in the afterwar time when women were pushed back home again from the wartime labor market and when several of the goals reached by the first phase of feminist movements had gone lost in several European countries under Fascist or semi-fascist regimes and were being eroded in America by the reactionary climate of McCarthyism. It was a book written by an intellectual young woman in almost total isolation. These circumstances account for some more naïve suggestions from work: for ex., the idea that the alternative to the strategy once adopted by nineteenth-century emancipationist movements should be an individual inner process of transformation confined within the boundaries of one woman’s consciousness, or also, the idea that the goal of women’s liberation should be to bring all women to a condition similar of Simone de Beauvoir herself who, as an educated woman, earning her life by her work, and living in an allegedly equal state with an enlightened man (Jean-Paul Sartre!) in a relationship free from constraints (an unmarried couple!), was already exemplifying what a liberated woman’s life would be. -/- 3. The reconstruction of the idea of femininity is still the most fruitful part of the work. It rejects the notion of femininity as an essence depending on biology or other factors and explores the making of this image as a result of a condition made of the social and economic state of affairs but as revived and actively mirrored through and by the consciousness of the very subjects suffering an oppressive situation. And the main novelty is the ‘discovery’ of asymmetry between the self-image of the male and the (self)-image of the woman, an asymmetry depending on the fact that the woman sees herself through the other’s eyes. -/- 4. Later feminist writers such as Shulamit Firestone remarked that 'The Second Sex' heavily depended on several key-ideas from Sartre existential ontology. One crucial aspect is accepting the mind-body dualistic framework without any suspicion that such dualism could have been itself a projection of the basic experience of the male-female duality. I suggest that the philosophical legacy inherited from Sartre is on occasion an asset for Beauvoir’s innovative existential analysis of the feminine ‘condition,’ but on several occasions, it creates unnecessary obstacles for her project of a new comprehension of the feminine ‘situation,’ aimed at rescuing women from an 'inauthentic' self-definition. -/- 5. The first among these poisoned gifts is Sartre’s idea of the individual as pure freedom and project. Merleau-Ponty’s criticism is well-known: Sartre draws a picture of the world as containing no more than ‘human beings and things,’ thus denying any substance to social relations, institutions, and culture. -/- 6. The second is Sartre’s reconstruction of dialectics, understood as dialectics without synthesis. This is an enlightening tool when used to describe conflicts, in so far as it accounts for the emergence of the ‘other’ as what is excluded. But it becomes a boomerang when used to interpret any kind of relationship, leading to equate inter-subjectivity with conflict. -/- 7. Suggestions coming from Merleau-Ponty’s phenomenological approach of positive value of the bodily dimension as such, and hence of the feminine body, are evoked here and there but never fully spelled out. The most shocking consequence of acceptance of the Cartesian or Sartrean dualist view is an almost total de-evaluation of sexuality, understood as an activity involving just one tiny part of the human body, going with the idea that overcoming the oppression of women implies de-empathizing biological differences that are after all tiny and devoid of value. Besides, Beauvoir falls back into the trap of grounding claims of equality between men and women on the assumption that biological differences are of limited relevance. The eventual reason for such a step back is the distorting Cartesian mirror into which Beauvoir still looks in the vain hope of discovering a disembodied self as the (Cartesian) subject of an impossible kind of liberation.The first among these poisoned gifts is Sartre’s idea of the individual as pure freedom and project.

Recently, there is a renewed debate concerning the role of perspective in vision. Morales et al. (2020) present evidence that, in the case of viewing a rotated coin, the visual system is sensitive to what has often been called “perspectival shapes.” It has generated vigorous discussions, including an online symposium by Morales and Cohen, an exchange between Linton (2021) and Morales et al. (2021), and most recently, a fierce critique by Burge and Burge (2022), in which they launch various conceptual (...) and empirical objections. Although Morales and Firestone (2022) have responded to them recently, and we are in agreement with Morales and Firestone in general, there are further problems in Burge and Burge (2022) that are worth highlighting. The main point of this comment is that what the Burge–Burge team call “viewpoint-dependent relational properties” are simply instances of what the Morales–Firestone team call “perspectival shapes”; the confusion arises from Burge and Burge’s misconstrual of Morales et al.’s claims. This shows that conceptually, the two teams are in large agreement, as Morales and Firestone (2022) also point out, and the focus should be put on the empirical disagreements, which has been covered by Morales and Firestone (2022). Relatedly, we argue that Burge and Burge (2022) misinterpret Morales et al. (2020) as supporting a new entity in perception science, and that this misinterpretation is a primary source of their apparent disagreement. This is worth pointing out because such misunderstanding generates many unnecessary quarrels that hinder progress. (shrink)

We provide empirical examples to conceptually clarify some items on Firestone & Scholl’s (F&S’s) checklist, and to explain perceptual effects from an attentional and memory perspective. We also note that action and embodied cognition studies seem to be most susceptible to misattributing attentional and memory effects as perceptual, and identify four characteristics unique to action studies and possibly responsible for misattributions.

Historical reconstructions of the effects of the intellectual migration are typically informed by one of two conflicting narratives. Some scholars argue that refugee philosophers, in particular the logical positivists, contributed to the demise of distinctly American schools of thought. Others reject this ‘eclipse view’ and argue that postwar analytic philosophy can best be characterized as a synthesis of American and positivist views. This paper studies the fate of one of the most influential schools of U.S. philosophy—Columbia naturalism—and argues that both (...) narratives are part of a larger story. First, I reconstruct the rise of the Columbia school, focusing on its naturalist analyses of science, morality, and religion as well as its contributions to the history of ideas. Next, I trace some of the naturalists’ contacts with German philosophers and show that they encountered a strong bifurcation between historical and scientific philosophy in their discussions. I argue that a similar distinction gradually infected debates between naturalists, eventually resulting in a split within the Columbia school itself. The historically-oriented naturalists, I argue, were overshadowed by the analytic movement, whereas the science-minded naturalists were able to incorporate the views of the émigrés, thereby developing the tradition in new directions.

Presenting an Open Peer Commentary on “In Maturana’s Wake: The Biology of Cognition’s Legacy and its Prospects” by Randall Whitaker, the article suggests that engaging with Maturana's biology of cognition in the context of design is a form of practice rather than application. Maturana's biology of cognition, the article argues, can be conceived of as initiating an educational process that supports agents to act “from within” rather than “from without.”.

This essay is my review of Randal Marlin’s fine book, Propaganda and the Ethics of Persuasion (2nd Ed.). Marlin’s book examines the concept of propaganda, rightly noting that the term has a neutral meaning of just promulgating a point of view and a pejorative meaning of using deceit to push a point of view. Marlin gives a concise history of propaganda techniques, and propaganda theory—from ancient Greece through WWII—and has a good discussion of the ethical issues involved in propaganda.

Does the human mind resemble the machines that can behave like it? Biologically inspired machine-learning systems approach “human-level” accuracy in an astounding variety of domains, and even predict human brain activity—raising the exciting possibility that such systems represent the world like we do. However, even seemingly intelligent machines fail in strange and “unhumanlike” ways, threatening their status as models of our minds. How can we know when human–machine behavioral differences reflect deep disparities in their underlying capacities, vs. when such failures (...) are only superficial or peripheral? This article draws on a foundational insight from cognitive science—the distinction between performance and competence—to encourage “species-fair” comparisons between humans and machines. The performance/competence distinction urges us to consider whether the failure of a system to behave as ideally hypothesized, or the failure of one creature to behave like another, arises not because the system lacks the relevant knowledge or internal capacities (“competence”), but instead because of superficial constraints on demonstrating that knowledge (“performance”). I argue that this distinction has been neglected by research comparing human and machine behavior, and that it should be essential to any such comparison. Focusing on the domain of image classification, I identify three factors contributing to the species-fairness of human–machine comparisons, extracted from recent work that equates such constraints. Species-fair comparisons level the playing field between natural and artificial intelligence, so that we can separate more superficial differences from those that may be deep and enduring. (shrink)

Whereas decades of research have cataloged striking errors in physical reasoning, a resurgence of interest in intuitive physics has revealed humans’ remarkable ability to successfully predict the unfolding of physical scenes. A leading interpretation intended to resolve these opposing results is that physical reasoning recruits a general-purpose mechanism that reliably models physical scenarios (explaining recent successes), but overly contrived tasks or impoverished and ecologically invalid stimuli can produce poor performance (accounting for earlier failures). But might there be tasks that persistently (...) strain physical understanding, even in naturalistic contexts? Here, we explore this question by introducing a new intuitive physics task: evaluating the strength of knots and tangles. Knots are ubiquitous across cultures and time-periods, and evaluating them correctly often spells the difference between safety and peril. Despite this, 5 experiments show that observers fail to discern even very large differences in strength between knots. In a series of two-alternative forced-choice tasks, observers viewed a variety of simple “bends” (knots joining two pieces of thread) and decided which would require more force to undo. Though the strength of these knots is well-documented, observers’ judgments completely failed to reflect these distinctions, across naturalistic photographs (E1), idealized renderings (E2), dynamic videos (E3), and even when accompanied by schematic diagrams of the knots’ structures (E4). Moreover, these failures persisted despite accurate identification of the topological differences between the knots (E5); in other words, even when observers correctly perceived the underlying structure of the knot, they failed to correctly judge its strength. These results expose a blindspot in physical reasoning, placing new constraints on general-purpose theories of scene understanding. (shrink)

Seeing is not believing, contrary to what popular idioms might claim. But what exactly is the difference? This question is the focus of The Border Between Seeing and Thinking, the long-awaited monograph by philosopher Ned Block.

Shuford, Albert and Massengill proved, a half century ago, that the logarithmic scoring rule is the only proper measure of inaccuracy determined by a differentiable function of probability assigned the actual cell of a scored partition. In spite of this, the log rule has gained less traction in applied disciplines and among formal epistemologists that one might expect. In this paper we show that the differentiability criterion in the Shuford et. al. result is unnecessary and use the resulting simplified characterization (...) of the logarithmic rule to give novel arguments in favor of it.

Character education in schools has been high on the UK political agenda for the last few years. The government has invested millions in grants to support character education projects and declared its intention to make Britain a global leader in teaching character and resilience. But the policy has many critics: some question whether schools should be involved in the formation of character at all; others worry that the traits schools are being asked to cultivate are excessively competitive or military. In (...) this pamphlet Randall Curren sets out a robust defence of character education. He welcomes the political support it presently enjoys, but contends that greater clarity about the nature, benefits and acquisition of good character is essential. In particular, he argues that too narrow a focus on traits like perseverance and resilience is a serious mistake: these traits are only virtues when they are part of a wider set of moral and intellectual qualities, and when their exercise is guided by good judgment. Curren offers us a compelling and coherent account of what good character is and how it might be cultivated in schools. He explains why schools must be needs-supporting environments that provide students with opportunities to engage in rewarding activity, and why cultivating good character implies promoting the ‘fundamental British values’ of democracy, the rule of law, individual liberty, and mutual respect and tolerance. His groundbreaking pamphlet promises to expand the scope and strengthen the foundations of character education in British schools, and should go a long way towards allaying the fears of its detractors.

What is the relationship between complexity in the world and complexity in the mind? Intuitively, increasingly complex objects and events should give rise to increasingly complex mental representations (or perhaps a plateau in complexity after a certain point). However, a counterintuitive possibility with roots in information theory is an inverted U-shaped relationship between the “objective” complexity of some stimulus and the complexity of its mental representation, because excessively complex patterns might be characterized by surprisingly short computational descriptions (e.g., if they (...) are represented as having been generated “randomly”). Here, we demonstrate that this is the case, using a novel approach that takes the notion of “description” literally. Subjects saw static and dynamic visual stimuli whose objective complexity could be carefully manipulated, and they described these stimuli in their own words by giving freeform spoken descriptions of them. Across three experiments totaling over 10,000 speech clips, spoken descriptions of shapes (Experiment 1), dot-arrays (Experiment 2), and dynamic motion-paths (Experiment 3) revealed a striking quadratic relationship between the raw complexity of these stimuli and the length of their spoken descriptions. In other words, the simplest and most complex stimuli received the shortest descriptions, while those stimuli with a “medium” degree of complexity received the longest descriptions. Follow-up analyses explored the particular words used by subjects, allowing us to further explore how such stimuli were represented. We suggest that the mind engages in a kind of lossy compression for overly complex stimuli, and we discuss the utility of such freeform responses for exploring foundational questions about mental representation.

Some things look more complex than others. For example, a crenulate and richly organized leaf may seem more complex than a plain stone. What is the nature of this experience—and why do we have it in the first place? Here, we explore how object complexity serves as an efficiently extracted visual signal that the object merits further exploration. We algorithmically generated a library of geometric shapes and determined their complexity by computing the cumulative surprisal of their internal skeletons—essentially quantifying the (...) “amount of information” within each shape—and then used this approach to ask new questions about the perception of complexity. Experiments 1–3 asked what kind of mental process extracts visual complexity: a slow, deliberate, reflective process (as when we decide that an object is expensive or popular) or a fast, effortless, and automatic process (as when we see that an object is big or blue)? We placed simple and complex objects in visual search arrays and discovered that complex objects were easier to find among simple distractors than simple objects are among complex distractors—a classic search asymmetry indicating that complexity is prioritized in visual processing. Next, we explored the function of complexity: Why do we represent object complexity in the first place? Experiments 4–5 asked subjects to study serially presented objects in a self‐paced manner (for a later memory test); subjects dwelled longer on complex objects than simple objects—even when object shape was completely task‐irrelevant—suggesting a connection between visual complexity and exploratory engagement. Finally, Experiment 6 connected these implicit measures of complexity to explicit judgments. Collectively, these findings suggest that visual complexity is extracted efficiently and automatically, and even arouses a kind of “perceptual curiosity” about objects that encourages subsequent attentional engagement.

We offer a critical evaluation of a recent proposal of E. Tal and J. Comesa\~na on the topic of when evidence of evidence constitutes evidence. After establishing that attempts of L. Moretti and W. Roche to discredit the proposal miss their mark, we fashion another, which does not.

Our best social scientific theories try to tell us something about the social world. But is talk of a “social world” a metaphor that we ought not take too seriously? In particular, do the denizens of the social world—cultural values like the Protestant work ethic, firms like ExxonMobil, norms like standards of dress and behavior, institutions like the legal system, teams like FC Barcelona, conventions like marriages—exist? The question is not merely academic. Social scientists use these different social entities to (...) explain social phenomena such as the rise of capitalism, the decline in oil prices, or the effect of unions on the sports labor market. But how could these explanations possibly work if social entities don’t exist? (shrink)

Among the extant masterworks of Roman art, there is probably none that has generated more scholarly debate than the Portland Vase over the interpretation of its elegant frieze. No fewer than forty-four different theories attempting to interpret the scenes on the vase have appeared in the last 400 years. In the main, the theories fall into two categories, those relating the frieze to Greek myth, and those linking the figures to Roman personages. Moreover, there is no consensus whether the frieze (...) is two separate scenes or one continuous story. The obstacle to interpreting the frieze is that all but one of the figures lack identifying attributes. This paper will demonstrate (1) that in lieu of standard iconography, a synthesis of visual and literary tropes in the form of hidden letters, that is, cryptograms, tells the viewer how to read the frieze; (2) that scene A of the frieze illustrates specifically lines 26-30 of Catullus 64 by visually rendering the epithets and tropes used in those lines; (3) that visual reproductions of other tropes in Catullus 64 further substantiate the relationship between frieze and poem; (4) that scene B of the frieze is an intentional aberration from the poem; (5) that there is a complex and unfinished interaction between scenes A and B which the viewer must complete; and (6) that in the final analysis, the frieze duplicates both the theme and central structure of Catullus 64.10 .

All interpretations of the Portland Vase frieze to date have failed to see, much less explain, a crucial figural attribute in the frieze, one that proves to be both explicit and explicatory, and whose location and appearance secures the identification of not one but, indeed, three figures. Furthermore, the attribute lies at the heart of a distinct schema of figural grouping and arrangement which has also gone unheeded in previous treatments of the Portland Vase frieze. By dint of this previously (...) unknown attribute, one can straightforwardly read the opening scene of the frieze using the attributes therein provided, but the opening scene only. To complete the task, a second methodology–that which I laid out in Arion in 1992–is a categorical sine qua non. One can, as I have already shown, successfully navigate the entire frieze using the second methodology alone but, as so many others have shown, not contrariwise. These new findings–the attribute and figural plan–are clear proof that the artistic vision of the Portland Vase was purposefully executed in a two-part program. (shrink)
