In the remainder of this article, we will disarm an important motivation for epistemic contextualism and interest-relative invariantism. We will accomplish this by presenting a stringent test of whether there is a stakes effect on ordinary knowledge ascription. Having shown that, even on a stringent way of testing, stakes fail to impact ordinary knowledge ascription, we will conclude that we should take another look at classical invariantism. Here is how we will proceed. Section 1 lays out some limitations of previous (...) research on stakes. Section 2 presents our study and concludes that there is little evidence for a substantial stakes effect. Section 3 responds to objections. The conclusion clears the way for classical invariantism.

This paper presents and motivates a new philosophical and logical approach to truth and semantic paradox. It begins from an inferentialist, and particularly bilateralist, theory of meaning---one which takes meaning to be constituted by assertibility and deniability conditions---and shows how the usual multiple-conclusion sequent calculus for classical logic can be given an inferentialist motivation, leaving classical model theory as of only derivative importance. The paper then uses this theory of meaning to present and motivate a logical system---ST---that conservatively extends classical (...) logic with a fully transparent truth predicate. This system is shown to allow for classical reasoning over the full (truth-involving) vocabulary, but to be non-transitive. Some special cases where transitivity does hold are outlined. ST is also shown to give rise to a familiar sort of model for non-classical logics: Kripke fixed points on the Strong Kleene valuation scheme. Finally, to give a theory of paradoxical sentences, a distinction is drawn between two varieties of assertion and two varieties of denial. On one variety, paradoxical sentences cannot be either asserted or denied; on the other, they must be both asserted and denied. The target theory is compared favourably to more familiar related systems, and some objections are considered. (shrink)

In How We Get Along, philosopher David Velleman compares our social interactions to the interactions among improvisational actors on stage. He argues that we play ourselves - not artificially but authentically, by doing what would make sense coming from us as we really are. And, like improvisational actors, we deal with one another in dual capacities: both as characters within the social drama and as players contributing to the shared performance. In this conception of social intercourse, Velleman finds rational (...) grounds for morality, though not a rational guarantee. He maps a middle course between skepticism and rationalism, arguing that practical reasoning is 'pro-moral' without requiring moral action. The result is what he calls a 'Kinda Kantian metaethics'. How We Get Along is the summation of Velleman's thinking to date, incorporating and unifying previous work on agency, the self, the emotions, narrative and Kantian moral theory. (shrink)

Two separate research programs have revealed two different factors that feature in our judgments of whether some entity persists. One program—inspired by Knobe—has found that normative considerations affect persistence judgments. For instance, people are more inclined to view a thing as persisting when the changes it undergoes lead to improvements. The other program—inspired by Kelemen—has found that teleological considerations affect persistence judgments. For instance, people are more inclined to view a thing as persisting when it preserves its purpose. Our goal (...) in this paper is to determine what causes persistence judgments. Across four studies, we pit normative considerations against teleological considerations. And using causal modeling procedures, we find a consistent, robust pattern with teleological and not normative considerations directly causing persistence judgments. Our findings put teleology in the driver’s seat, while at the same time shedding further light on our folk notion of an object. (shrink)

This book introduces readers to the topic of explanation. The insights of Plato, Aristotle, J.S. Mill and Carl Hempel are examined, and are used to argue against the view that explanation is merely a problem for the philosophy of science. Having established its importance for understanding knowledge in general, the book concludes with a bold and original explanation of explanation.

How do we determine whether some candidate causal factor is an actual cause of some particular outcome? Many philosophers have wanted a view of actual causation which fits with folk intuitions of actual causation and those who wish to depart from folk intuitions of actual causation are often charged with the task of providing a plausible account of just how and where the folk have gone wrong. In this paper, I provide a range of empirical evidence aimed at showing just (...) how and where the folk go wrong in determining whether an actual causal relation obtains. The evidence suggests that folk intuitions of actual causation are generated by two epistemically defective processes. I situate the empirical evidence within a background discussion of debunking, arguing for a two-pronged debunking explanation of folk intuitions of actual causation. I conclude that those who wish to depart from folk intuitions of actual causation should not be compelled to square their account of actual causation with the verdicts of the folk. In the dispute over actual causation, folk intuitions deserve to be rejected. (shrink)

Since the 18th century, one of the key features of diagnosed psychopaths has been “moral colorblindness” or an inability to form moral judgments. However, attempts at experimentally verifying this moral incapacity have been largely unsuccessful. After reviewing the centrality of “moral colorblindness” to the study and diagnosis of psychopathy, I argue that the reason that researchers have been unable to verify that diagnosed psychopaths have an inability to make moral judgments is because their research is premised on the assumption that (...) there is a specific moral faculty of the brain, or specific “moral” emotions, and that this faculty or set of emotions can become “impaired”. I review recent research and argue that we have good reason to think that there is no such distinct capacity for moral judgment, and that, as a result, it is impossible for someone’s “moral judgment faculty” to become selectively disabled. I then discuss the implications of such a position on psychopathy research, the coherence of the disorder, and the moral responsibility of psychopaths. (shrink)

This paper consider Prior's connective Tonk from a particular bilateralist perspective. I show that there is a natural perspective from which we can see Tonk and its ilk as perfectly well-defined pieces of vocabulary; there is no need for restrictions to bar things like Tonk.

According to the Principle of Sufficient Reason, every fact has an explanation. An important challenge to this principle is that it risks being a counterexample to itself. What explains why everything needs to be explained? My first goal is to distinguish two broad kinds of answers to this question, which I call “Humean Rationalism” and “Non-Humean Rationalism”. My second goal will be to defend the prospects of Humean Rationalism.

Many philosophers maintain that causation is to be explicated in terms of a kind of dependence between cause and effect. These “dependence” theories are opposed by “production” accounts which hold that there is some more fundamental causal “oomph”. A wide range of experimental research on everyday causal judgments seems to indicate that ordinary people operate primarily with a dependence-based notion of causation. For example, people tend to say that absences and double preventers are causes. We argue that the impression that (...) commonsense causal discourse is largely dependence-based is the result of focusing on a very narrow class of causal verbs. Almost all of the vignette-based experimental work on causal judgment has been prosecuted using the word “cause”. But much ordinary causal discourse involves special causal verbs, such as “burn” and “crack”. We find that these verbs display a quite different pattern from the verb “cause”. For instance, for absences and double preventers (Studies 1-3), we find that while people are inclined to say that X caused Y to burn, turn, crack or start, they are less inclined to think that X burned, turned, cracked or started Y. In Study 4, we find that for chains involving a distal and proximal event, people are inclined to say that the distal event is not a special cause of the outcome, though it is a “cause” of the outcome. Together, we find a surprising double dissociation between “cause” and a stock of special causal verbs. We conclude by suggesting that much commonsense causal judgment, which heavily trades in special causal verbs, might be better captured by production-based accounts of causation. (shrink)

We argue that there is significant evidence for reconsidering the possibility that moral judgment constitutes a distinctive category of judgment. We begin by reviewing evidence and arguments from neuroscience and philosophy that seem to indicate that a diversity of brain processes result in verdicts that we ordinarily consider “moral judgments”. We argue that if these findings are correct, this is plausible reason for doubting that all moral judgments necessarily share common features: if diverse brain processes give rise to what we (...) refer to as “moral judgments”, then we have reason to suspect that these judgments may have different features. After advancing this argument, we show that giving up the unity of moral judgment seems to effectively dissolve the internalism/externalism debate concerning motivation within the field of metaethics.

Empirical research has recently emerged as a key method for understanding the nature of causation, and our concept of causation. One thread of research aims to test intuitions about the nature of causation in a variety of classic cases. These experiments have principally been used to try to resolve certain debates within analytic philosophy, most notably that between proponents of transference and dependence views of causation. The other major thread of empirical research on our concept of causation has investigated the (...) role that normative considerations play in causal judgments. These experimental results suggest that philosophical accounts of our concept of causation should take a broader view of what might be relevant. For both lines of research, we describe some of the significant experiments and outline key philosophical morals that have been drawn, all while pointing out various limitations. We conclude by considering other kinds of empirical research that should be philosophically interesting for those studying the nature of causation and our concept of causation. In particular, we point towards the need for philosophical research about causal perception, causal reasoning, and causal learning, as well as ways in which this research could play a role in prescriptive metaphysics.

Many philosophers have claimed that the folk endorse moral universalism. Some have taken the folk view to support moral universalism; others have taken the folk view to reflect a deep confusion. And while some empirical evidence supports the claim that the folk endorse moral universalism, this work has uncovered intra-domain differences in folk judgments of moral universalism. In light of all this, our question is: why do the folk endorse moral universalism? Our hypothesis is that folk judgments of moral universalism (...) are generated in part by a desire to punish. We present evidence supporting this across three studies. On the basis of this, we argue for a debunking explanation of folk judgments of moral universalism. Our results not only further our understanding of the psychological processes underpinning folk judgments of moral universalism. They also bear on philosophical discussions of folk meta-ethics.

Is behavioral integration (i.e., which occurs when a subjects assertion that p matches her non-verbal behavior) a necessary feature of belief in folk psychology? Our data from nearly 6,000 people across twenty-six samples, spanning twenty-two countries suggests that it is not. Given the surprising cross-cultural robustness of our findings, we suggest that the types of evidence for the ascription of a belief are, at least in some circumstances, lexicographically ordered: assertions are first taken into account, and when an agent sincerely (...) asserts that p, non-linguistic behavioral evidence is disregarded. In light of this, we take ourselves to have discovered a universal principle governing the ascription of beliefs in folk psychology. (shrink)

I argue that the debate concerning the nature of first-person moral judgment, namely, whether such moral judgments are inherently motivating or whether moral judgments can be made in the absence of motivation, may be founded on a faulty assumption: that moral judgments form a distinct kind that must have some shared, essential features in regards to motivation to act. I argue that there is little reason to suppose that first-person moral judgments form a homogenous class in this respect by considering (...) an ordinary case: student readers of Peter Singer’s “Famine, Affluence, and Morality”. Neither internalists nor externalists can provide a satisfying account as to why our students fail to act in this particular case, but are motivated to act by their moral judgments in most cases. I argue that the inability to provide a satisfying account is rooted in this shared assumption about the nature of moral judgments. Once we consider rejecting the notion that first-person moral decision- making forms a distinct kind in the way it is typically assumed, the internalist/externalist debate may be rendered moot.

Many philosophers insist that the revisionary metaphysician—i.e., the metaphysician who offers a metaphysical theory which conflicts with folk intuitions—bears a special burden to explain why certain folk intuitions are mistaken. I show how evidence from cognitive science can help revisionist discharge this explanatory burden. Focusing on composition and persistence, I argue that empirical evidence indicates that the folk operate with a promiscuous teleomentalist view of composition and persistence. The folk view, I argue, deserves to be debunked. In this way, I (...) take myself to have illustrated one key role cognitive science can play in metaphysics; namely by helping the revisionary metaphysician discharge the explanatory burden of providing a plausible explanation of how the folk have gone wrong.

Does the Ship of Theseus present a genuine puzzle about persistence due to conflicting intuitions based on “continuity of form” and “continuity of matter” pulling in opposite directions? Philosophers are divided. Some claim that it presents a genuine puzzle but disagree over whether there is a solution. Others claim that there is no puzzle at all since the case has an obvious solution. To assess these proposals, we conducted a cross-cultural study involving nearly 3,000 people across twenty-two countries, speaking eighteen (...) different languages. Our results speak against the proposal that there is no puzzle at all and against the proposal that there is a puzzle but one that has no solution. Our results suggest that there are two criteria—“continuity of form” and “continuity of matter”— that constitute our concept of persistence and these two criteria receive different weightings in settling matters concerning persistence.

According to a popular idea, freedom is grounded in orthonomy – the ability to be responsive to normative demands. But how exactly must an agent’s action relate to their reasons in order for this orthonomous relationship to hold? In this paper, I propose a novel explanationist answer to this question. I argue that extant answers – causalism and modalism about orthonomy – fail because they fail to account for the fact that intuitions about freedom and orthonomy track facts about explanation. (...) And these facts cannot be reduced to either causal or modal facts. Instead, I propose that we should understand freedom as grounded in special accidentality-dispersing explanations in terms of normative reasons. The resultant view is to be understood as following a Frankfurtian intuition: only factors that explain action can be relevant to whether the action is free. (shrink)

Realists about aesthetic judgment believe something like the following: for an aesthetic judgment of be correct, it must respond to the intrinsic aesthetic properties possessed by the object in question (e.g., Meskin et al., 2013; Kieran 2010). However, Cutting’s (2003) empirical research on aesthetic judgment puts pressure on that position. His work indicates that unconscious considerations extrinsic to an artwork can underpin said judgements. This paper takes Cutting’s conclusion a step further: If philosophers grant that it’s possible to appreciate artwork (...) on the basis of unconscious biases, then we never can be fully confident that our aesthetic judgment is undergirded by the intrinsic aesthetic properties of an artwork. Furthermore, if judgment on the basis of unconscious, external reasons cannot be ruled out, we cannot be confident that our aesthetic judgments are ‘correct’. I argue that Cutting’s research is just the tip of the iceberg regarding the extrinsic, unconscious factors that influence aesthetic judgment. Expectation bias formed via social influence and context greatly influence aesthetic judgments and are unavoidable: we inevitably form expectations based on all kinds of contextual cues independently of any actual exposure to the item in question. Such factors make it terribly difficult to be confident in our aesthetic judgments. Even if there are objective properties that mark out some items as aesthetically superior to others, we cannot be sure that our judgments are responding to those properties. (shrink)

In this paper, I suggest that the wrongness of many—though not at all—cases of microaggressions can be captured as cases of negligence. A case of negligence holds when, regardless of an actor’s intentions, he or she wrongs another in a manner that is both reasonably foreseeable and reasonably avoidable. Thinking of microaggressions as negligence answers some objections of skeptics who focus on the possibility that the alleged microaggressor “meant no offense”. It does so while retaining language explaining why a wrong (...) was committed and suggesting what sort of corrective behavior can reasonably be demanded to avoid these wrongs in the future. I also argue that a negligence framework does a better job of phenomenologically explaining most microaggressions—both why they occur and why they are perceived as the sort of conduct that subjects the microaggressor to agent-level moral criticism. Indeed, I believe that negligence-style logic permeates many accounts that already exist regarding microaggressions, albeit without fully being recognized. Finally, in cases where it applies, the negligence framework has an advantage over alternate accounts in that it provides for consideration of both the moral culpability of the perpetrator as well as the tangible impact of microaggressions on the victim.

Justification has long been considered a necessary condition for knowledge, and theories that deny the necessity of justification have been dismissed as nonstarters. In this chapter, we challenge this long-standing view by showing that many of the arguments offered in support of it fall short and by providing empirical evidence that individuals are often willing to attribute knowledge when epistemic justification is lacking.

In philosophy of aesthetics, scholars commonly express a commitment to the premise that there is a distinctive type of judgment that can be meaningfully labeled “aesthetic”, and that these judgments are distinctively different from other types of judgments. We argue that, within an Aristotelian framework, there is no clear avenue for meaningfully differentiating “aesthetic” judgment from other types of judgment, and, as such, we aim to question the assumption that aesthetic judgment does in fact constitute a distinctive kind of judgment (...) that is in need of, or can be subject to, distinctive theorizing. We advance our argument primarily through demonstrating that leading contemporary accounts of aesthetic judgment do not successfully distinguish a type of judgment in that they do not tell us how making an aesthetic judgment differs substantially from judging that 2 + 3 = 5, that football is entertaining, or that today is Tuesday.

One way to interpret the work of Joshua Greene (2001; 2008; 2014) is that the wave of empirical research into moral decision-making is a way for us to become more confident in our ability to gain moral knowledge. We argue that empirical research into moral judgment has shown (both survey-based and brain-based) that the grounds of moral judgment are opaque on several dimensions. We argue that we cannot firmly grasp what the morally relevant/irrelevant features of a decision context are, understand (...) which cognitive system responds to said features, and further know that we are actually basing our judgment upon what we take to be the morally relevant features. That is, we argue that moral judgment is very much like other kinds of judgment: Deeply influenced by facts about the decision-context and the decision-maker. However, if moral judgment is merely the exercise of our general judgment making faculty, we shouldn’t be surprised by this result. We conclude by considering what this means for our practice of making moral judgments. (shrink)

When people make sense of situations, illustrations, instructions and problems they do more than just think with their heads. They gesture, talk, point, annotate, make notes and so on. What extra do they get from interacting with their environment in this way? To study this fundamental problem, I looked at how people project structure onto geometric drawings, visual proofs, and games like tic tac toe. Two experiments were run to learn more about projection. Projection is a special capacity, similar to (...) perception, but less tied to what is in the environment. Projection, unlike pure imagery, requires external structure to anchor it, but it adds ‘mental’ structure to the external scene much like an augmented reality system adds structure to an outside scene. A person projects when they look at a chessboard and can see where a knight may be moved. Because of the cognitive costs of sustaining and extending projection, humans make some of their projections real. They create structure externally. They move the piece, they talk, point, notate, represent. Much of our interactivity during sense making and problem solving involves a cycle of projecting then creating structure. (shrink)

Informing others about the world is often a helpful act. In this paper, I study agents who conduct experiments to gather information about the world, committing in advance to fully disclose the nature of the experiment together with all experimental findings. While this appears to be a benign activity, I characterize a type of exploitative informing that is possible even within this restricted setup. I show how exploitative informants use public experiments to predictably manipulate interlocutors’ beliefs and actions to their (...) own advantage. I discuss epistemic and practical grounds on which it may be permissible for agents to resist acts of exploitative informing, then conclude by discussing implications for epistemic injustice and duties to gather evidence.

A given causal system can be represented in a variety of ways. How do agents determine which variables to include in their causal representations, and at what level of granularity? Using techniques from Bayesian networks, information theory, and decision theory, we develop a formal theory according to which causal representations reflect a trade-off between compression and informativeness, where the optimal trade-off depends on the decision-theoretic value of information for a given agent in a given context. This theory predicts that, all (...) else being equal, agents prefer causal models that are as compressed as possible. When compression is associated with information loss, however, all else is not equal, and our theory predicts that agents will favor compressed models only when the information they sacrifice is not informative with respect to the agent’s anticipated decisions. We then show, across six studies reported here (N=2,364) and one study reported in the supplemental materials (N=182), that participants’ preferences over causal models are in keeping with the predictions of our theory. Our theory offers a unification of different dimensions of causal evaluation identified within the philosophy of science (proportionality and stability), and contributes to a more general picture of human cognition according to which the capacity to create compressed (causal) representations plays a central role.

In a recent paper, Firt, Hemmo and Shenker argue that Hempel’s dilemma, typically thought to primarily undermine physicalism, is generalizable and impacts mind-body dualism and many other theories equally. I challenge this view and argue that Hempel’s dilemma admits of at least two distinct construals: a general-skeptical construal, underpinned by historically driven arguments such as the pessimistic induction, and a non-skeptical construal, driven by the specific puzzles and volatility of current physics. While the general-skeptical construal applies to all changeable deep-structure (...) theories, the non-skeptical construal primarily targets volatile theories which harbor exclusionary ambitions. As a result, dualism largely evades both construals due to the stability of theories of the mental and their lack of exclusionary ambitions. Conversely, physicalism is uniquely susceptible to both construals due to its strong commitment to deep-structure realism, inherent exclusionary ambitions, and the volatility of certain branches of fundamental physics. The paper ultimately concludes that Hempel’s dilemma is not universally problematic, but presents a unique challenge to physicalism while being relatively congenial to dualism. (shrink)

This essay aims to vindicate the thesis that cognitive computational properties are abstract objects implemented in physical systems. I avail of Voevodsky's Univalence Axiom and function type equivalence in Homotopy Type Theory, in order to specify an abstraction principle for epistemic (hyper-)intensions. The homotopic abstraction principle for epistemic (hyper-)intensions provides an epistemic conduit for our knowledge of (hyper-)intensions as abstract objects. Higher observational type theory might be one way to make first-order abstraction principles defined via inference rules, although not higher-order (...) abstraction principles, computable. The truth of my first-order abstraction principle for hyperintensions is grounded in its being possibly recursively enumerable i.e. Turing computable and the Turing machine being physically implementable. Epistemic modality and hyperintensionality can thus be shown to be both a compelling and a materially adequate candidate for the fundamental structure of mental representational states, comprising a fragment of the language of thought.

In this paper, we consider Noël Carroll’s Content Theory (CT) (2015) and argue that a key problem with CT is that it can be interpreted in two distinct ways: as a descriptive theory of aesthetic experience and as a normative prescriptive theory. Although CT is presented as a descriptive theory of experience, much of what Carroll says implies that CT can also be understood as a theory about how one ought to look at artworks. We argue that when understood as (...) a descriptive theory, CT fails to qualify as a meaningful theory of aesthetic experience. We then interpret the theory prescriptively. Ultimately, this second interpretation is also found lacking: if the aim of the theory is to instruct one on how to view art, it is no longer an attempt to characterize the experience of art. We conclude by arguing that the main flaw in CT is its approach: we cannot meaningfully characterize an experience by enumerating the objects that supposedly cause said experience, and any theory that takes such an approach is likely to be unsuccessful.

An experiment was performed to test the hypothesis that people sometimes take physical actions to make themselves more effective problem solvers. The task was to generate all possible words that could be formed from seven Scrabble letters. In one condition, participants could use their hands to manipulate the letters, and in another condition, they could not. Results show that more words were generated with physical manipulation than without. However, an interaction was obtained between the physical manipulation conditions and the specific (...) letter sets chosen, indicating that physical manipulation helps more for generating words in some circumstances than in others. Overall, our findings can be explained in terms of an interactive search process in which external, physical activity effectively complements internal, cognitive activity. Within this framework, the interaction can be explained in terms of the relative difficulty of generating words from the letters given in the different sets. (shrink)

Jason Brennan and Peter Jaworski argue in recent work that “semiotic” or “symbolic” objections to markets are unsuccessful. I counter-argue that there are indeed some semiotic limits on markets and that anti-commodification theorists are not merely expressing disgust when they disapprove of markets in certain goods on those grounds. One central argument is that, contrary to what Brennan and Jaworski claim, semiotic arguments against markets do not depend fundamentally on meanings that prevail about markets. Rather, they depend on the meanings (...) that attach to various goods, meanings that give us moral bases on which to make judgments about their prospective commodification. (shrink)

This paper argues that an individualist perspective is a crucial element of William James’s metaphilosophical outlook. In broad outline, the individualist argument the paper attributes to James can be characterized like this. Disputes among philosophers about the optimal point of view from which to consider this or that philosophical problem are themselves only adequately adjudicated from an individualist perspective. That is, when it comes to an assortment of important philosophical questions (not all of them perhaps, but a significant number), an (...) individualist perspective should replace a more objective one, and whether it should or not is itself a question that should be decided from an individualist perspective.

This paper revisits some of the arguments in Richard Rorty’s Achieving Our Country, twenty years after the book first appeared. Not only are many of Rorty’s diagnoses and predictions eerily prescient in the wake of the rise of Donald Trump to the US presidency, but there is also perceptive political advice in Rorty’s book that I argue the contemporary American Left would do well to heed. While many post-election commentators have tended to read Achieving Our Country as an admonishment of (...) so-called “identity politics” in favor of an “old Left” politics of redistribution and economic justice, I argue that the main distinction on which the analysis in Achieving Our Country hangs is between what Rorty calls “real politics” and “cultural politics”, a conclusion that is confirmed, I argue, by examining the three concrete suggestions for the American Left that together form the core positive argument in Rorty’s book.

In this paper, I motivate skepticism about the causal efficacy of moral properties in two ways. First, I highlight a tension that arises between two claims that moral realists may want to accept. The first claim is that physically indistinguishable things do not differ in any causally efficacious respect. The second claim is that physically indistinguishable things that differ in certain historical respects have different moral properties. The tension arises to the extent to which these different moral properties are supposed (...) to have different effects on people. I will introduce a class of cases in which this tension arises and suggest that the moral properties in these cases have no causal power. I will also question whether there are differences between the moral properties in these cases and moral properties in other cases that do not involve physically indistinguishable things that could make the latter moral properties causally efficacious. The second way that I motivate skepticism consists in pointing out a unique feature of cases in which moral properties are supposed both to supervene on historical properties and to be causally efficacious. These cases allow us to change moral properties with alleged effects while we hold constant the nonmoral candidates for causal contribution to those effects. This feature of these cases is unique because in most other cases the moral properties supervene on the physical properties in the nonmoral candidates, such that we cannot change the former while holding constant the latter. This way of changing moral properties provides empirical grounds for testing their causal efficacy. (shrink)

Part of a Festschrift for Fred Miller, this essay reconsiders Miller's interpretation of Aristotle in terms of natural rights. After defending Miller against his numerous critics, I draw a somewhat different lesson from his interpretation than he himself does: Miller helps us to see that an Aristotelian theory of justice can do all the work that we would reasonably want a theory of rights to do while avoiding significant problems that the idiom and rhetoric of rights tend to generate.

We present data and argument to show that in Tetris—a real-time interactive video game—certain cognitive and perceptual problems are more quickly, easily, and reliably solved by performing actions in the world rather than by performing computational actions in the head alone. We have found that some translations and rotations are best understood as being used to implement a plan, or to implement a reaction. To substantiate our position we have implemented a computational laboratory that lets us record keystrokes and game (...) situations, as well as allows us to dynamically create situations. Using the data of over 30 subjects playing 6 games, tachistoscopic tests of some of these subjects, and results from our own successful efforts at building expert systems to play Tetris, we show why knowing how to use one’s environment to enhance speed and robustness are important components in skilled play.

Al-Taftāzānī introduces the Liar Paradox, in a commentary on al-Rāzī, in a short passage that is part of a polemic against the ethical rationalism of the Muʿtazila. In this essay, we consider his remarks and their place in the history of the Liar Paradox in Arabic Logic. In the passage, al-Taftāzānī introduces Liar Cycles into the tradition, gives the paradox a puzzling name—the fallacy of the “irrational root” —which became standard, and suggests a connection between the paradox and what it (...) tells us about truth and falsehood, and arguments for divine voluntarism and what they tell us about the nature of goodness and badness. On this last point, we also discuss a passage from al-Rāzī, which suggests similar connections. (shrink)

The degree to which information is encoded explicitly in a representation is related to the computational cost of recovering or using the information. Knowledge that is implicit in a system need not be represented at all, even implicitly, if the cost of recurring it is prohibitive.

A common response to claims of bias, harassment, or discrimination is to say that these claims are made in bad faith. Claimants are supposedly not motivated by a credible or even sincere belief that unfair or unequal treatment has occurred, but simply seek to illicitly gain public sympathy or private reward. Characterizing discrimination claims as systematically made in bad faith enables them to be screened and dismissed prior to engaging with them on their merits. This retort preserves the dominant group’s (...) self-image as unprejudiced and innocent without having to risk critical analysis of the claim’s substance. (shrink)

Abstract:This article raises a series of doubts about Chris Voparil’s reading of Rorty, particularly the claim that what he calls “Rorty’s Pragmatic Maxim” represents what is at the heart of his philosophical vision. Those doubts are tied together with some scattered thoughts about how Voparil describes the affinities between Rorty and William James in chapter 2 of Reconstructing Pragmatism. Voparil is correct to claim that it is James, more than any other figure in the pragmatist tradition, who shares the most (...) with Rorty in “basic philosophical orientation”. Yet I also argue that Voparil fails to correctly puts his finger on what that “basic philosophical orientation” really comes to, due in large part to an excessively political reading of James and Rorty that he relies on.

The question of how to conceive and represent the context of work is explored from the theoretical perspective of distributed cognition. It is argued that to understand the office work context we need to go beyond tracking superficial physical attributes such as who or what is where and when and consider the state of digital resources, people’s concepts, task state, social relations, and the local work culture, to name a few. In analyzing an office more deeply, three concepts are especially (...) helpful: entry points, action landscapes, and coordinating mechanisms. An entry point is a structure or cue that represents an invitation to enter an information space or office task. An activity landscape is part mental construct and part physical; it is the space users interactively construct out of the resources they find when trying to accomplish a task. A coordinating mechanism is an artifact, such as a schedule or clock, or an environmental structure such as the layout of papers to be signed, which helps a user manage the complexity of his task. Using these three concepts we can abstract away from many of the surface attributes of work context and define the deep structure of a setting—the invariant structure that many office settings share. A long-term challenge for context-aware computing is to operationalize these analytic concepts. (shrink)

Time is one of humankind’s unanswerable mysteries. Aristotle called time “the most unknown of unknown things.” What time is and even if it objectively exists are unanswerable questions. Time is intangible. -/- There have been and will be countless theories about time. Many, including in science, are simply useful definitions or conventions, and each is looking at time in a particular way and for a particular purpose. This paper looks at a variety of significant perspectives from physics, philosophy and psychology. (...) A key is to demonstrate that there are many different incomplete and subjective ways of looking at what ultimately is beyond our mental grasp. (shrink)

From religion to philosophy to science, all human systems of definition are formed by human brains. The nature and limits of the human brain are the nature and limits of those systems.

There are many conditions and instances where the brain processes information unusually, including mental disorders, physical events, and drug use. This essay focuses on the neurological events called (...) mystical experiences. (shrink)

To discover how to couple reflection with reaction we have been studying how people play the computer game Tetris. Our basic intuition is that the job of the reasoned is to monitor the environment and the agent’s behavior over time to discover trends or deviations from the agent’s normative policy and tune the priorities of the Attentional system accordingly.

This text examines recent illiberal trends in traditionally liberal institutions. Specifically, it critiques radical “anti-racism” approaches based on critical race theory (CRT) and the ideas of academics such as Ibram X. Kendi and Robin DiAngelo. It also focuses on Unitarian Universalism, a historically liberal church whose national leadership has adopted an extreme version of critical race theory. -/- Racial and other inequities are problems in all societies and all of human history, and there are no simple, easy or objectively correct (...) solutions. While critical race theory (CRT) offers important insights on racism and racial disparities, I believe in liberalism, freedom of speech and the free exchange of ideas, things that extreme CRT adherents, Kendi and DiAngelo oppose. -/- Freedom of speech and expression and the free exchange of ideas support diversity, multiculturalism and marginalized groups. Illiberalism, dogmatism and authoritarianism are oppressive of all groups, minority and majority, and should be rejected wherever they appear. (shrink)

I have spent 40 years looking for a coherent and convincing way of formulating my worries about what, if anything, philosophy is good for. Richard Rorty had an unusually avid interest in metaphilosophy. Again and again he would return to questions about the practical uses (if any) to which philosophy might be put, about philosophy's role in intellectual culture, about what philosophy is or might become. His answers to these questions were famously negative: philosophy's practical uses are few, its cultural (...) role marginal. Philosophy is or will be whatever we make of it. Yet it is one thing to have given up on the idea of Philosophy as a Fach with a naturally occurring canon of problems, or in terms of the closely .. (shrink)

The following looks at several problems and questions concerning our understanding of the word ‘intelligence’ and the phrase ‘artificial intelligence’ (AI), including: how to define these terms; whether intelligence can exist in AI; if artificial intelligence in AI is identifiable; and what (if any) kind of intelligence is important to AI.

Do young children have a teleological conception of the essence of natural kinds? We tested this by examining how the preservation or alteration of an animal’s purpose affected children’s persistence judgments (N = 40, ages 4 - 12, Mean Age = 7.04, 61% female). We found that even when surface-level features of an animal (e.g., a bee) were preserved, if the entity’s purpose changed (e.g., the bee now spins webs), children were more likely to categorize the entity as a member (...) of a different natural kind (e.g., a spider) and these effects were similar in magnitude to altering the surface-features of a natural kind. Our results suggest that we might view teleological properties as partially constitutive of the essence of natural kinds. (shrink)
