Graeme Forbes (2011) raises some problems for two-dimensional semantic theories. The problems concern nested environments: linguistic environments where sentences are nested under both modal and epistemic operators. Closely related problems involving nested environments have been raised by Scott Soames (2005) and Josh Dever (2007). Soames goes so far as to say that nested environments pose the “chief technical problem” for strong two-dimensionalism. We call the problem of handling nested environments within two-dimensional semantics “the nesting problem”. We show that the two-dimensional (...) semantics for attitude ascriptions developed in Chalmers (2011a) has no trouble accommodating certain forms of the nesting problem that involve factive verbs such as “know” or “establish”. A certain form of the nesting problem involving apriority and necessity operators does raise an interesting puzzle, but we show how a generalized version of the nesting problem arises independently of two-dimensional semantics—it arises, in fact, for anyone who accepts the contingent a priori. We, then, provide a two-dimensional treatment of the apriority operator that fits the two-dimensional treatment of attitude verbs and apply it to the generalized nesting problem. We conclude that two-dimensionalism is not seriously threatened by cases involving the nesting of epistemic and modal operators. (shrink)

This appeared in Philosophy and Phenomenological Research 59:473-93, as a response to four papers in a symposium on my book The Conscious Mind . Most of it should be comprehensible without having read the papers in question. This paper is for an audience of philosophers and so is relatively technical. It will probably also help to have read some of the book.

David Chalmers’s book is impressive in many ways. I admire the great skill, incisiveness and breadth of vision with which he conducts his argument. Many of his controversial theses and intuitions I find congenial. Unfortunately I do not believe the book’s central thesis, namely, that facts about consciousness are not physical facts. Much of the book is devoted either to establishing this, or to considering how things stand in the light of it. Let me quote a passage in which (...) Chalmers’s thesis is stated. (shrink)

Chalmers’s anti-materialist argument runs as follows.

Where does philosophy, the oldest academic subject, stand at the beginning of the new millennium? This remarkable volume brings together leading figures from most major branches of the discipline to offer answers. What remains of the "linguistic turn" in twentieth-century philosophy? How should moral philosophy respond to and incorporate developments in empirical psychology? Where might Continental and Anglophone feminist theory profitably interact? How has our understanding of ancient philosophy been affected by the emergence of analytic philosophy? Where does the mind-body (...) problem stand today? What role must value judgments play in science? Do Marx, Nietzsche, or Freud matter in the 21st century? These and many other questions at the cutting edge of the discipline are addressed by distinguished philosophers from Australia, Britain, Canada, and the United States. They aim not only to stimulate philosophical debate, but to introduce those in cognate disciplines--biology, classics, economics, history, law, linguistics, literary studies, mathematics, philosophy, physics, political science, psychology, among others--to what is happening in contemporary philosophy. In a substantial introduction, the editor gives an overview of the state of philosophy today and helps orient non-philosophers.

Daniel Dennett (1996) has disputed David Chalmers' (1995) assertion that there is a "hard problem of consciousness" worth solving in the philosophy of mind. In this paper I defend Chalmers against Dennett on this point: I argue that there is a hard problem of consciousness, that it is distinct in kind from the so-called easy problems, and that it is vital for the sake of honest and productive research in the cognitive sciences to be clear about the difference. (...) But I have my own rebuke for Chalmers on the point of explanation. Chalmers (1995, 1996) proposes to "solve" the hard problem of consciousness by positing qualia as fundamental features of the universe, alongside such ontological basics as mass and space-time. But this is an inadequate solution: to posit, I will urge, is not to explain. To bolster this view, I borrow from an account of explanation by which it must provide "epistemic satisfaction" to be considered successful (Rowlands, 2001; Campbell, 2009), and show that Chalmers' proposal fails on this account. I conclude that research in the science of consciousness cannot move forward without greater conceptual clarity in the field. (shrink)

David Chalmers claims that the logical possibility of ‘zombie worlds’ — worlds physically indiscernible from the actual world, but that lack consciousness — reveal that consciousness is a distinct fact, or property, in addition to the physical facts or properties.The ‘existence’ or possibility of Zombie worlds violates the physicalist demand that consciousness logically supervene upon the physical. On the assumption that the logical supervenience of consciousness upon the physical is, indeed, a necessary entailment of physicalism, the existence of zombie (...) worlds implies the falsity of physicalism. How do we determine the logical possibility of zombie worlds? By conceptual analysis of the concepts involved, keeping empirical facts in mind. (shrink)

In recent work, David Chalmers argues that “Edenic shapes”—roughly, the shape properties phenomenally presented in spatial experience—are not instantiated in our world. His reasons come largely from the theory of Special Relativity. Although Edenic shapes might have been instantiated in a classical Newtonian world, he maintains that they could not be instantiated in a relativistic world like our own. In this essay, I defend realism about Edenic shape, the thesis that Edenic shapes are instantiated in our world, against (...) class='Hi'>Chalmers’s challenge from Special Relativity. I begin by clarifying the notion of an Edenic shape by reference to Chalmers’s notion of the “Edenic” content of perceptual experience. I then reconstruct Chalmers’s argument that Edenic shapes could not be instantiated in a relativistic world. His reasoning proceeds from two assumptions. The first is that the only shape properties instantiated in a relativistic world are those which somehow involve relations to frames of reference. This is thought to follow from the phenomenon of Lorentz contraction, a consequence of Special Relativity. The second assumption is that Edenic shapes do not involve relations to frames of reference. One reason to accept the second assumption is that it seems that Edenic shapes could be instantiated in a classical Newtonian world, where the notion of a frame-relative shape has no meaningful application. I then proceed to defend RES against Chalmers’s argument by arguing that Special Relativity, properly understood, provides no support for Chalmers’s first assumption. More generally, I argue, by way of a careful analysis of the geometric structure of Minkowski space–time and Galilean space–time Newtonian physics), that Edenic shapes are no less at home in a relativistic world than in a classical Newtonian world.

Daniel Dennett has claimed that if Chalmers' argument for the irreducibility of consciousness were to succeed, an analogous argument would establish the truth of Vitalism. Chalmers denies that there is such an analogy. I argue that the analogy does have merit and that skepticism is called for.

I argue that our sensory fields are photon fields. The philosophical foundation here is informed by mind/brain identity theory, such as we find in Russell, Feigl, Lockwood and Chalmers. In brief, given Dyson's observation that all material things consist of quantum fields, and given an identity of mind and brain, our sensory fields are then most plausibly photon fields.

Building on earlier papers on the same theme, Chalmers argues here for a dualism which is epiphenomenalist, yet naturalistic. After establishing the elements of his position, Chalmers explores numerous applications, including arguments against missing and inverted qualia; the congeniality of his view to panpsychism, functionalism, and artificial intelligence, and even the proper interpretation of quantum physics.

In a recent paper, Brian Rabern suggests a semantics for languages with two kinds of modality, standard Kripkean metaphysical modality as well as epistemic modality. This semantics presents an alternative to two-dimensionalism, which was developed in the last decades. Both Rabern’s semantics and two-dimensionalism are subject to a puzzle that Chalmers and Rabern, 210–224 2014) call the nesting problem. I will investigate how Rabern’s semantics answers this puzzle.

In June 2001, the American Medical Association (AMA) issued a revised and expanded version of the Principles of Medical Ethics (last published in 1980). In light of the new and more comprehensive document, the present essay is geared to consideration of a longstanding tension between physician's autonomy rights and societal obligations in the AMA Code. In particular, it will be argued that a duty to treat overrides AMA autonomy rights in social emergencies, even in cases that involve personal risk to (...) physicians (e.g., bioterrorist attack, HIV infection, SARS). The argument will be made by way of the logic and language of the AMA Code through its history, commentaries, and precedents. It also will be shown that there are substantial reasons to believe that the logic of the Code is sound in morally relevant ways. The essay will conclude with some philosophical proposals suggesting a framework for the duty to render aid and the extension of those duties to physicians facing personal risks. (shrink)

Scientific Essentialism defends the view that the fundamental laws of nature depend on the essential properties of the things on which they are said to operate, and are therefore not independent of them. These laws are not imposed upon the world by God, the forces of nature or anything else, but rather are immanent in the world. Ellis argues that ours is a dynamic world consisting of more or less transient objects which are constantly interacting with each other, and whose (...) identities depend on their roles in these processes. Natural objects must behave as they do, because to do otherwise would be contrary to their natures. The laws of nature are, therefore, metaphysically necessary, and consequently, there are necessary connections between events. Brian Ellis calls for the rejection of the theory of Humean Supervenience and an implementation of a new kind of realism in philosophical analysis. (shrink)

Trust relations in medicine are argued to be a requisite response to the special vulnerability of persons as patients. Even so, the problem of motivating trust remains a vital concern. On this score, it is argued that a strong motivation can be found in recognizing that professional self-interest actually entails cultivation of patient trust as a means to maintain professional self-governance. And while the initial move to restore trust must be provoked from such narrow concerns, the process of sustaining trust (...) will require educational initiatives aimed at restoring attitudes and skills suggestive of Percival's concept of empathic care. By including such initiatives, future waves of medical professionals are apt to sustain trust with deepened commitments to character, care, and trust as constitutive properties of their professional mission.

Dualists say plausible things about our mental concepts: there is a way of thinking of pain, in terms of how it feels, which is independent of causal role. Physicalists make attractive ontological claims: the world is wholly physical. The attraction of a posteriori physicalism is that it has seemed to do both: to agree with the dualist about our mental concepts, whilst retaining a physicalist ontology. In this paper I argue that, in fact, a posteriori physicalism departs from the dualist's (...) intuitive picture of our phenomenal concepts in just as radical a manner as more traditional forms of physicalism. Whereas the physicalism of David Lewis and David Armstrong is counterintuitive in holding that our only way of thinking about pain is in terms of its causal role, the physicalism of David Papineau and Brian Loar departs from common sense in holding that our phenomenal concept of pain is opaque: thinking of pain in terms of how it feels reveals nothing of what it is for something to feel pain. The arguments of David Chalmers and Frank Jackson against a posteriori physicalism involve general claims about all concepts. In contrast, my argument makes a claim only about phenomenal concepts: phenomenal concepts are not opaque. (shrink)

Multidimensional concepts are everywhere, and they are important. Examples include moral value, welfare, scientific confirmation, democracy, and biodiversity. How, if at all, can we aggregate the underlying dimensions of a multidimensional concept F to yield verdicts about which things are Fer than which overall? Social choice theory can be used to model and investigate this aggregation problem. Here, we focus on a particularly thorny problem made salient by this social choice-theoretic framework: the underlying dimensions of a given concept might be (...) measurable on different types of scales—e.g., some ordinal and some cardinal. An underappreciated impossibility theorem due to Anna Khmelnitskaya shows that seemingly plausible constraints on aggregation across scale types are inconsistent. This impossibility threatens to render the notion of overall Fness incoherent. We attempt to defuse this threat, arguing that the impossibility depends on an overly restrictive conception of measurement and of how measurement constrains aggregation. Adopting a more flexible—and, we think, more perspicuous—conception of measurement opens an array of possibilities for aggregation across disparate scale types. (shrink)

In "The Philosophy of Nature," Brian Ellis provides a clear and forthright general summation of, and introduction to, the new essentialist position. Although the theory that the laws of nature are immanent in things, rather than imposed on them from without, is an ancient one, much recent work has been done to revive interest in essentialism and "The Philosophy of Nature" is a distinctive contribution to this lively current debate. Brian Ellis exposes the philosophical and scientific credentials of (...) the prevailing Humean metaphysic as less than compelling and makes the case for new essentialism as an alternative metaphysical perspective in lucid and unambiguous terms. This book develops this alternative metaphysic and considers the consequences for philosophy, and for some other areas of investigation, of working with such a metaphysic. Ellis argues that these consequences are profound and that a new essentialism provides a comprehensive new philosophy of nature for a modern scientific understanding of the world. (shrink)

The gist of the many-subjects argument is that, given physicalism, it’s hard to avoid the absurd result that there are many conscious subjects in your vicinity with more-or-less the same experiences as you. The most promising ways of avoiding this result have a consequence almost as bad: that there are many things in your vicinity that are in a state only trivially different from being conscious, a state with similar normative significance. This paper clarifies and defends three versions of the (...) many-subjects argument. One version poses the threat of conscious parts. Its key premise is that if physicalism is true, then not only you, but also certain parts of your body, are conscious. These parts might include your brain, your head, all-of-you-except-your-left-pinky, all-of-your-brain-except-one-neuron, or your left cerebral hemisphere. A second version poses the threat of conscious coinciders, things that currently occupy the same spatial region as you and share all your matter. Its key premise is that if physicalism is true, then not only you, but also some things that currently coincide with you, are conscious. These might include your body or the aggregate of particles of which you are currently composed. A third version poses the threat of conscious person candidates, the many human-body-shaped material objects in your vicinity that mostly overlap one another, differing only in a few peripheral atoms. This version claims that if physicalism is true, then there are many conscious person-candidates in your vicinity. -/- . (shrink)

The view that properties have their causal powers essentially, which I will here call property essentialism, has advocates in Chris Swoyer,[1] Sydney Shoemaker [2], Alan Chalmers [3], Brian Ellis [4] and Caroline Lierse [5], among a few other authors in recent literature. I am partial to this view as well and I will shortly explain the grounds I find compelling in favor of it. However, we will also see that the essentialist view of properties and laws does not (...) adequately do quite so much as might be hoped. Property essentialism has the straightforward result that at least causal laws are metaphysically necessary. A natural view of such laws is that they are analyses of the essential nature of basic properties in terms of their essential causal powers. Brian Ellis proposes that conservation laws and other laws that may not be exactly causal are best thought of as characterizing the essential properties of worlds. But this further essentialist thesis is not directly relevant to the issues I want to address here. (shrink)

In this essay it is shown that the imaginative art of scientific theorizing – at its technical best – animates Quine's philosophy as importantly as the more Spartan norms honored in his present pantheon of virtues. By drawing a contrast between the standing of theories in philosophy and theories in science, it will be shown that the speculative reaches of philosophy, along with developments in semantic theory, now oblige an internal revision of Quine's stance against meaning as it was announced (...) in “Two Dogmas of Empiricism.” So, corollary to this proposed revision, I argue that in natural philosophy, the muse of the “art of science” deserves an address along with the more Spartan norms in Quine's present philosophical pantheon. As semantic theory and analyticity thus gain a measure of philosophical tenability, Quine's holism emerges as the more central doctrine of his mature vision. (shrink)

While acknowledging its theory-ladeness, Chalmers (history and philosophy, U. of Sydney) defends the objectivity of scientific knowledge against those critics for whom such knowledge is both subjective and ideological.

What makes an object the same persisting individual over time? Philosophers and psychologists have both grappled with this question, but from different perspectives—philosophers conceptually analyzing the criteria for object persistence, and psychologists exploring the mental mechanisms that lead us to experience the world in terms of persisting objects. It is striking that the same themes populate explorations of persistence in these two very different fields—e.g. the roles of spatiotemporal continuity, persistence through property change, and cohesion violations. Such similarities may reflect (...) an underlying connection, in that psychological mechanisms of object persistence (especially relevant parts of mid-level visual object processing) may serve to underlie the intuitions about persistence that fuel metaphysical theories. This would be a way for cognitive science to join these two disparate fields, helping to explain the possible origins and reliability of some metaphysical intuitions, and perhaps leading to philosophical progress.

In _What Animals Teach Us about Politics_, Brian Massumi takes up the question of "the animal." By treating the human as animal, he develops a concept of an animal politics. His is not a human politics of the animal, but an integrally animal politics, freed from connotations of the "primitive" state of nature and the accompanying presuppositions about instinct permeating modern thought. Massumi integrates notions marginalized by the dominant currents in evolutionary biology, animal behavior, and philosophy—notions such as play, (...) sympathy, and creativity—into the concept of nature. As he does so, his inquiry necessarily expands, encompassing not only animal behavior but also animal thought and its distance from, or proximity to, those capacities over which human animals claim a monopoly: language and reflexive consciousness. For Massumi, humans and animals exist on a continuum. Understanding that continuum, while accounting for difference, requires a new logic of "mutual inclusion." Massumi finds the conceptual resources for this logic in the work of thinkers including Gregory Bateson, Henri Bergson, Gilbert Simondon, and Raymond Ruyer. This concise book intervenes in Deleuze studies, posthumanism, and animal studies, as well as areas of study as wide-ranging as affect theory, aesthetics, embodied cognition, political theory, process philosophy, the theory of play, and the thought of Alfred North Whitehead.

The epistemic norms should matter. The ones philosophers typically focus on do not matter enough. They should be replaced. This book discusses a range of views of why and how epistemic norms could matter and shows how epistemic norms as standardly understood fall short on each. No matter how the importance of the epistemic is to be explained, it does not matter at all what we believe about most topics or why we believe it. When what we believe does matter, (...) it is often not particularly important that our beliefs are true, but rather that they are good enough for our purposes, and thus no truth-connected epistemic notion such as reliability, evidence, coherence, accuracy, or knowledge is really relevant. Finally, even when truth is genuinely important, standard epistemic norms do not properly aim at the truth, because they do not allow us to sacrifice one true belief for the sake of others. In light of all of this, epistemic norms as standardly conceived are not really concerned with what matters. We can and should do better. The epistemic norms that genuinely matter will replace truth-based epistemic notions with conceptions of success, reasons, and justification aimed at the “good enough.” They will require us to form some seemingly bad beliefs—beliefs that violate all standard norms by going against our evidence, being incoherent, or even being clearly false—in order to improve other beliefs. In fact, they will sometimes allow our beliefs to be bad for no reason whatsoever. (shrink)

Color coded terror alerts, invasion, drone war, rampant surveillance: all manifestations of the type of new power Brian Massumi theorizes in _Ontopower_. Through an in-depth examination of the War on Terror and the culture of crisis, Massumi identifies the emergence of preemption, which he characterizes as the operative logic of our time. Security threats, regardless of the existence of credible intelligence, are now felt into reality. Whereas nations once waited for a clear and present danger to emerge before using (...) force, a threat's felt reality now demands launching a preemptive strike. Power refocuses on what _may_ emerge, as that potential presents itself to feeling. This affective logic of potential washes back from the war front to become the dominant mode of power on the home front as well. This is ontopower—the mode of power embodying the logic of preemption across the full spectrum of force, from the “hard” to the "soft". With _Ontopower_, Massumi provides an original theory of power that explains not only current practices of war but the culture of insecurity permeating our contemporary neoliberal condition.

Moral realism faces a well known genealogical debunking challenge. I argue that the moral realist’s best response may involve abandoning metaphysical naturalism in favor of some form of axiarchism—the view, very roughly, that the natural world is “ordered to the good.” Axiarchism comes in both theistic and non-theistic forms, but all forms agree that the natural world exists and has certain basic features because it is good for it to exist and have those features. I argue that theistic and non-theistic (...) forms of axiarchism are better positioned than metaphysical naturalism to avoid two commitments that a moral realist should seek to avoid: that the correctness of our moral beliefs is a major coincidence, and that there is a complete explanation of our moral beliefs that does not mention any moral truths.

most famous and, arguably, most important papers in modern aesthetics. Despite this, and the various references to it and discussions of it within the literature, there are no general commentaries on this essay. In addition to outlining a general framework for approaching the article, I identify and explicate the two main exegetical issues regarding it. The first concerns how to understand Walton's main thesis that the aesthetic character of artworks is determined, in part, by their ‘correct category’. I suggest that (...) the traditional interpretation of Walton's proposal is mistaken, and defend an alternative view at length. The second issue concerns the relationship between Walton's view and competing accounts of the aesthetics of artworks. Here I suggest that Walton's position is unique, contrasting the views of both typical formalists, on the one hand, and ordinary contextualists, on the other, in philosophically significant ways. Careful reflection on this particular issue helps reveal some very important distinctions among aesthetic theories, which have not been previously drawn or emphasized.

A counterpossible is a counterfactual whose antecedent is impossible. The vacuity thesis says all counterpossibles are true solely because their antecedents are impossible. Recently, some have rejected the vacuity thesis by citing purported non-vacuous counterpossibles in science. One limitation of this work, however, is that it is not grounded in experimental data. Do scientists actually reason non-vacuously about counterpossibles? If so, what is their basis for doing so? We presented biologists (N = 86) with two counterfactual formulations of a well-known (...) model in biology, the antecedents of which contain what many philosophers would characterize as a metaphysical impossibility. Participants consistently judged one counterfactual to be true, the other to be false, and they explained that they formed these judgments based on what they perceived to be the mathematical relationship between the antecedent and consequent. Moreover, we found no relationship between participants’ judgments about the (im)possibility of the antecedent and whether they judged a counterfactual to be true or false. These are the first experimental results on counterpossibles in science with which we are familiar. We present a modal semantics that can capture these judgments, and we deal with a host of potential objections that a defender of the vacuity thesis might make. (shrink)

The old adage has two people out hiking who run into a bear. One starts running while the other asks ‘why are you running? You can’t outrun a bear’. To which the other responds, ‘I don’t have to outrun the bear. I only have to outrun you’. Hiking/trekking is not typically a competitive endeavor characterized by contests but, like many endeavors/pursuits/activities, competition can be injected into it; thereby sportifying it. Swimming is a sport (under certain conditions). At the same time, (...) it is also a recreational activity and a form of physical exercise; likewise angling/fishing, climbing, cross-country skiing, mountain biking, kayaking, rowing, surfing, et al. The categorization of many activities under the umbrella of sport has it uses to understand the wider concept of what is sport, but the purpose of why one engages in ‘physical activities taking place in a natural environment’ can sometimes be more important than whether some activities might or might not qualify to be classified under the rubric of sports at all. Indicators exist to show whether participants are actually engaged toward—driven in a way, even—to further their skills in their focused activity (if it is a focused activity at all!––i.e. a ‘serious leisure’ pursuit or just a recreational hobby). From this perspective (of looking at sport-like and sporting activities in other than Olympic-style forms) this paper explores the differentiations between sport (including nature sport) contests, nature challenge activities (NCAs) and outdoor recreation from the standpoint of the most relevant factors that distinguish them: rules, skill development, purpose for engaging in them. This paper also makes the case that differentiating participants in the above activities by purpose (as either nature challenge recreationalists or nature sport devotees) has utility; to better help research into people’s engagement in physical activities in natural environments.

A field K in a ring language $\mathcal {L}$ is finitely undecidable if $\mbox {Cons}(T)$ is undecidable for every nonempty finite $T \subseteq {\mathtt{Th}}(K; \mathcal {L})$.

We conclude (assuming the NIP Fields Conjecture) that every NIP field is finitely undecidable. This work is drawn from the author’s PhD thesis [48, Chapter 3].

The Protagoras is the touchstone of Socrates’ moral intellectualist stance. The position in a nutshell stipulates that the proper reevaluation of a desire is enough to neutralize it.[1] The implication of this position is that akrasia or weakness of will is not the result of desire (or fear for that matter) overpowering reason but is due to ignorance. -/- Socrates’ eliminativist position on weakness of will, however, flies in the face of the common-sense experience regarding akratic action and thus Aristotle (...) was at pains to render Socrates’ account of moral incontinence intelligible. The key improvement Aristotle makes to Socrates’s model is to underscore that the conditioning of the akratic’s body plays a critical role in determining the power of one’s appetites and, accordingly, the capacity of one to resist the temptations these appetites present for rational evaluation. As Aristotle puts it, “For the incontinent man is like the people who get drunk quickly and on little wine, i.e., on less than most people.” (1151a 3-4). Aristotle presents what I shall call a somatic paradigm (i.e. the drunkard analogy) in order to tackle the problem of akrasia and it is this somatic solution that marks a significant improvement over Socrates’s intellectualist or informational model or so the tradition tells us. -/- In this paper, I wish to push back on the above Aristotelian explanation. I argue that when one fully examines Socrates’ account of weakness of will that Aristotle’s solution is less effective than is traditionally thought. In fact, Socrates can bring Aristotle’s model into his own; just as Aristotle absorbs what is right about Socrates’s model, namely, that akratic action utilizes reason but to a limited degree, Socrates in Meno (77C-78A) develops his own somatic model of weakness of will that connects to the intellectualist paradigm of the Protagoras. To achieve this rapprochement between the two models, I zero in on the description provided by Socrates of those individuals who desire bad things knowing they are bad as “ill-starred” or “bad spirited” (κακοδαίμων ). The “bad-spirited” is the coward and, in contrast to Aristotle’s drunkard, becomes fearful quickly from little danger. This additional somatic component, when connected to Socrates’s position on akrasia in Protagoras adds a new twist to Socrates’s model in the following way: while no one wishes to be ill-starred such that more harm than good will befall one, one may become so as a result of the bad choices one knowingly makes. -/- -/- [1] “After him came Socrates, who spoke better and further about this subject, but even he was not successful. For he used to make the virtues into sciences, and this is impossible. For the sciences all involve reason, and reason is to be found in the intellectual part of the soul. So that all the virtues, according to him arise in the rational part of the soul. The result is that in making the virtues into sciences he is doing away with the nonrational part of the soul and is thereby doing away with passion and character…” (Aristotle, Magna Moralia 1.1. 1182 a15-26).

A mathematical model in science can be formulated as a counterfactual conditional, with the model’s assumptions in the antecedent and its predictions in the consequent. Interestingly, some of these models appear to have assumptions that are metaphysically impossible. Consider models in ecology that use differential equations to track the dynamics of some population of organisms. For the math to work, the model must assume that population size is a continuous quantity, despite that many organisms are necessarily discrete. This means our (...) counterfactual representation of the model can have an impossible antecedent, giving us a counterpossible. Analogous counterpossibles arise in other sciences, as we’ll see. According to a prominent view in counterfactual semantics, the vacuity thesis, all counterpossibles are vacuously true, that is, true merely because their antecedents are necessarily false. But some counterpossible formulations of differential equation models in science are not all vacuously true—some are non-vacuously true, and some are false. I go on to show how an alternative semantics, one that employs impossible worlds, can deliver this judgment. (shrink)

The central thesis of this paper is that fake news and related phenomena serve as defeaters for knowledge transmission via journalistic channels. This explains how they pose a threat to democracy; and it points the way to determining how to address this threat. Democracy is both intrinsically and instrumentally good provided the electorate has knowledge (however partial and distributed) of the common good and the means of achieving it. Since journalism provides such knowledge, those who value democracy have a reason (...) to protect it. Hostile agents, however, can undermine both the effectiveness of democratic decision-making and faith in democracy itself, by deliberately promulgating fake news and hyper-partisan views; moreover, these effects can come about unintentionally on social media. I conclude that we may need to change, not just the way we process information online, but also the informational environment in which we operate. (shrink)

What question are decision theorists trying to answer, and why is it worth trying to answer it? A lot of philosophers talk as if the aim of decision theory is to describe how we should make decisions, and the reason to do this is to help us make better decisions. I disagree on both fronts. The aim of the decision theory is to describe how a certain kind of idealised decider does in fact decide. And the reason to do this (...) is that this idealisation, like many other idealisations, helps generate explanations of real-world behaviour. We shouldn't do what these ideal deciders do, or try to be more like them, because a lot of what they do only makes sense because of the differences between us and them. Still, sometimes those differences are small enough that they can be ignored in explanations, and that's when decision theory is useful. (shrink)

Frank Hindriks has attempted to derive a variant of Timothy Williamson’s knowledge rule for assertion on the basis of a more fundamental belief expression analysis of that speech act.

Safety-based theories of knowledge face a difficulty surrounding necessary truths: no subject could have easily falsely believed such a proposition. Failing to predict that ill-grounded beliefs in such propositions do not constitute knowledge, standard safety theories are therefore less informative than desired.

I suggest a solution to this problem: a belief is (...) safe iff its subject could not easily have believed a false answer to the same question. (shrink)

But how do we perceive an experience that encompasses the just-was and the is-about-to-be as much as what is actually present? In _Semblance and Event_, Brian Massumi, drawing on the work of William James, Alfred North Whitehead, Gilles Deleuze, and others, develops the concept of "semblance" as a way to approach this question. It is, he argues, a question of abstraction, not as the opposite of the (...) concrete but as a dimension of it: "lived abstraction." A semblance is a lived abstraction. Massumi uses the category of the semblance to investigate practices of art that are relational and event-oriented -- variously known as interactive art, ephemeral art, performance art, art intervention -- which he refers to collectively as the "occurrent arts." Each art practice invents its own kinds of relational events of lived abstraction, to produce a signature species of semblance. The artwork's relational engagement, Massumi continues, gives it a political valence just as necessary and immediate as the aesthetic dimension. (shrink)
