This article examines the complaint that arbitrary algorithmic decisions wrong those whom they affect. It makes three contributions. First, it provides an analysis of what arbitrariness means in this context. Second, it argues that arbitrariness is not of moral concern except when special circumstances apply. However, when the same algorithm or different algorithms based on the same data are used in multiple contexts, a person may be arbitrarily excluded from a broad range of opportunities. The third contribution is to explain (...) why this systemic exclusion is of moral concern and to offer a solution to address it. (shrink)

Shows that the very same asymmetries that arise for intentionally also arise from deciding, desiring, in favor of, opposed to, and advocating. It seems that the phenomenon is not due to anything about the concept of intentional action in particular. Rather, the effects observed for the concept of intentional action should be regarded as just one manifestation of the pervasive impact of moral judgment.

I defend an account of sexual orientation, understood as a reflexive disposition to be sexually attracted to people of a particular biological Sex or Sexes. An orientation is identified in terms of two aspects: the Sex of the subject who has the disposition, and whether that Sex is the same as, or different to, the Sex to which the subject is disposed to be attracted. I explore this account in some detail and defend it from several challenges. In doing so, (...) I provide a theoretical framework that justifies our continued reference to Sex-directed sexual orientation as an important means of classifying human subjects. (shrink)

Selective scientific realists disagree on which theoretical posits should be regarded as essential to the empirical success of a scientific theory. A satisfactory account of essentialness will show that the (approximate) truth of the selected posits adequately explains the success of the theory. Therefore, (a) the essential elements must be discernible prospectively; (b) there cannot be a priori criteria regarding which type of posit is essential; and (c) the overall success of a theory, or ‘cluster’ of propositions, not only individual (...) derivations, should be explicable. Given these desiderata, I propose a “unification criterion” for identifying essential elements. (shrink)

Physical boundaries and the earliest topologists. Topology has a relatively short history; but its 19th century roots are embedded in philosophical problems about the nature of extended substances and their boundaries which go back to Zeno and Aristotle. Although it seems that there have always been philosophers interested in these matters, questions about the boundaries of three-dimensional objects were closest to center stage during the later medieval and modern periods. Are the boundaries of an object actually existing, less-than-three-dimensional parts of (...) the object—that is, are solids bounded by two-dimensional surfaces, surfaces by one-dimensional “edges” or “physical lines”, edges by dimensionless “simples”? If not, how does a perfectly spherical object manage to touch a perfectly flat object—what part of the sphere is in immediate contact with the plane, if the sphere has no unextended parts? But if such parts be admitted, are we not then saddled with “actual infinities” of simples, lines, and surfaces spread throughout each continuous object—the boundaries of all the object’s internal parts? Does it help to say that these internal boundaries exist only “potentially”? (shrink)

This essay constitutes an attempt to probe the very idea of a saying/showing distinction of the kind that Wittgenstein advances in the Tractatus—to say what such a distinction consists in, to say what philosophical work it has to do, and to say how we might be justified in drawing such a distinction. Towards the end of the essay the discussion is related to Wittgenstein’s later work. It is argued that we can profitably see this work in such a way that (...) a saying/showing distinction arises there too. In particular, in the final sub-section of the essay, it is suggested that we can see in Wittgenstein’s later work an inducement to say what we are shown. (shrink)

Economic policy evaluations require social welfare functions for variable-size populations. Two important candidates are critical-level generalized utilitarianism (CLGU) and rank-discounted critical-level generalized utilitarianism, which was recently characterized by Asheim and Zuber (2014) (AZ). AZ introduce a novel axiom, existence of egalitarian equivalence (EEE). First, we show that, under some uncontroversial criteria for a plausible social welfare relation, EEE suffices to rule out the Repugnant Conclusion of population ethics (without AZ’s other novel axioms). Second, we provide a new characterization of CLGU: (...) AZ’s set of axioms is equivalent to CLGU when EEE is replaced by the axiom same-number independence. (shrink)

I argue that uniquely human forms of ‘Theory of Mind’ are a product of cultural evolution. Specifically, propositional attitude psychology is a linguistically constructed folk model of the human mind, invented by our ancestors for a range of tasks and refined over successive generations of users. The construction of these folk models gave humans new tools for thinking and reasoning about mental states—and so imbued us with abilities not shared by non-linguistic species. I also argue that uniquely human forms of (...) ToM are not required for language development, such that an account of the cultural origins of ToM does not jeopardise the explanation of language development. Finally, I sketch a historical model of the cultural evolution of mental state talk. (shrink)

Deafferented subjects, while lacking proprioceptive awareness of much of their bodies, are nevertheless able to use their bodies in basic action. Sustained visual contact with the body parts of which they are no longer proprioceptively aware enables them to move these parts in a controlled way. This might be taken to straightforwardly show that proprioceptive awareness is inessential to bodily action. I, however, argue that this is not the case. Proprioceptive awareness figures essentially in our self-conscious unity as practical subjects. (...) Recognizing this allows us to better understand the nature of the impairment with which deafferented subjects live. (shrink)

Frege's attempt to provide a foundation for the possibility of language and communication, like Kant's attempt to provide a foundation for the possibility of knowledge, fails to provide us with something absolute and foundational in a fixed sense. However, both these philosophers succeed in showing something about necessity that can be preserved independently of their absolutisms. Part III of this paper will provide reasons for accepting this thesis, while Parts I and II will provide an expository background on Frege's view (...) in preparation for supporting the thesis.

I recently argued that reductive physicalist versions of libertarian free will face a physical indeterminism luck objection. John Lemos claims that one potential advocate of reductive physicalist libertarianism, Robert Kane, avoids this physical indeterminism luck objection. I here show how the problem remains.

Despite a large and multifaceted effort to understand the vast landscape of phenotypic data, their current form inhibits productive data analysis. The lack of a community-wide, consensus-based, human- and machine-interpretable language for describing phenotypes and their genomic and environmental contexts is perhaps the most pressing scientific bottleneck to integration across many key fields in biology, including genomics, systems biology, development, medicine, evolution, ecology, and systematics. Here we survey the current phenomics landscape, including data resources and handling, and the progress that (...) has been made to accurately capture relevant data descriptions for phenotypes. We present an example of the kind of integration across domains that computable phenotypes would enable, and we call upon the broader biology community, publishers, and relevant funding agencies to support efforts to surmount today's data barriers and facilitate analytical reproducibility.

Scientific hedges are communicative devices used to qualify and weaken scientific claims. Gregor Betz has argued—unconvincingly, we think—that hedging can rescue the value-free ideal for science. Nevertheless, Betz is onto something when he suggests there are political principles that recommend scientists hedge public-facing claims. In this article, we recast this suggestion using the notion of public justification. We formulate and reject a Rawlsian argument that locates the justification for hedging in its ability to forge consensus. On our alternative proposal, hedging (...) is often justified because it renders scientific claims as publicly accessible reasons. (shrink)

Libertarian free will is, roughly, the view that agents cause actions to occur or not occur: Maddy’s decision to get a beer causes her to get up off her comfortable couch to get a beer, though she almost chose not to get up. Libertarian free will notoriously faces the luck objection, according to which agential states do not determine whether an action occurs or not, so it is beyond the control of the agent, hence lucky, whether an action occurs or (...) not: Maddy’s reasons for getting beer in equipoise with her reasons to remain in her comfortable seat do not determine that she will get up or stay seated, so it seems beyond her control, hence lucky, that she gets up. In this paper I consider a sub-set of the luck objection called the Physical Indeterminism Luck Objection, according to which indeterministic physical processes cause actions to occur or not, and agent’s lack control over these indeterministic physical processes, so agent’s lack control over, hence it is lucky, whether action occurs or not. After motivating the physical indeterminism luck objection, I consider responses from three recent event-causal libertarian models, and conclude that they fail to overcome the problem, though one promising avenue is opened up.

[A. W. Moore] Criteria of ineffability are presented which, it is claimed, preclude the possibility of truths that are ineffable, but not the possibility of other things that are ineffable—not even the possibility of other things that are non-trivially ineffable. Specifically, they do not preclude the possibility of states of understanding that are ineffable. This, it is argued, allows for a reappraisal of the dispute between those who adopt a traditional reading of Wittgenstein’s Tractatus and those who adopt the (...) new reading recently championed by Cora Diamond, James Conant, and others. By maintaining that what the nonsense in the Tractatus is supposed to convey is ineffable understanding, rather than ineffable truth, we can do considerable justice to each of these readings. We can also do considerable justice to the Tractatus. /// [Peter Sullivan] Moore proposes to cut between 'traditional' and 'new' approaches to the Tractatus, suggesting that Wittgenstein's intention is to convey, through the knowing use of nonsense, ineffable understanding. I argue, first, that there is indeed room for a proposal of Moore's general kind. Secondly, though, I question whether Moore's actual proposal is not more in tune with Wittgenstein's later thought than with the attitude of the Tractatus. (shrink)

Variable-Value axiologies avoid Parfit’s Repugnant Conclusion while satisfying some weak instances of the Mere Addition principle. We apply calibration methods to two leading members of the family of Variable-Value views conditional upon: first, a very weak instance of Mere Addition and, second, some plausible empirical assumptions about the size and welfare of the intertemporal world population. We find that such facts calibrate these two Variable-Value views to be nearly totalist, and therefore imply conclusions that should seem repugnant to anyone who (...) opposes Total Utilitarianism only due to the Repugnant Conclusion.

Researchers often lack the necessary data to credibly estimate racial discrimination in policing. In particular, police administrative records lack information on civilians police observe but do not investigate. In this article, we show that if police racially discriminate when choosing whom to investigate, analyses using administrative records to estimate racial discrimination in police behavior are statistically biased, and many quantities of interest are unidentified—even among investigated individuals—absent strong and untestable assumptions. Using principal stratification in a causal mediation framework, we derive (...) the exact form of the statistical bias that results from traditional estimation. We develop a bias-correction procedure and nonparametric sharp bounds for race effects, replicate published findings, and show the traditional estimator can severely underestimate levels of racially biased policing or mask discrimination entirely. We conclude by outlining a general and feasible design for future studies that is robust to this inferential snare. (shrink)

This paper examines rights and the protection of rights from both the minarchist and the anarchist perspectives. The former relies on Objectivist perspectives and the latter relies primarily on Murray Rothbard’s views. My view is that government protection as put forth by Objectivists is coercive, as are all methods of financing. However, under anarcho-capitalism, children who have been killed or abused by their caregivers do not have equal protection under the law. The principle of equal protection is one with which (...) both Objectivists and Rothbard agree. A case is made for government protection of rights under those circumstances. In addition, a case is made for positive rights to parental care for children, and also for government protection of those rights if they have been violated by their caregivers. I also argue for government oversight in instances when the rights of children have been violated and as a consequence the children have no alternative means of care. (shrink)

This paper concerns the familiar topic of whether we can have genuinely emotional responses such as pity and fear to characters and situations we believe to be fictional1. As is well known, Kendall Walton responds in the negative (Walton (1978); (1990): 195-204 and Chapter 7; (1997)). That is, he is an ‘irrealist’ about emotional responses to fiction (the term is Gaut’s (2003): 15), arguing that such responses should be construed as quasiemotions (Walton (1990): 245), of which their possessor imagines that (...) they are genuine emotions. This is not to deny that an experience in response to a fiction may have a phenomenology very like a given emotion, but to insist that, nonetheless, such responses are not real instances of the emotions which they resemble (Walton (1997)). So, in his most famous example, Charles, who experiences fear-like emotion in relation to a film which depicts the approach of evil slime, does not, despite appearances, experience genuine fear towards the slime, but only quasi-fear (Walton (1990): 195-204)2. Walton’s view presupposes the following view about the nature of emotion3. (shrink)

In Understanding Moral Obligation: Kant, Hegel, Kierkegaard, Robert Stern argues that Hegel has a social command view of obligation. On this view, there is an element of social command or social sanction that must be added to a judgment of the good in order to bring about an obligation. I argue to the contrary that Hegel's conception of conscience, and thus the individual's role in obligation, is more central to his account than the social dimension. While agreeing with Stern that (...) Hegel's conception of Sittlichkeit does preserve a role for obligation, and that the social plays an important part in that account, I argue that there is no extra social component that converts the morally good into obligation. Rather, Hegel's conception of Sittlichkeit as the “living good” means that judgments of the moral facts are simultaneously judgments of obligation. (shrink)

If humans have an evolved moral psychology, then we should not expect it to function in an identical way between individuals. Instead, we should expect a diversity in the function of our moral psychology between individuals that varies along genetic lines, and a corresponding diversity of moral attitudes and moral judgements that emerge from it. This is because there was no one psychological type that would reliably produce adaptive social behaviour in the highly heterogeneous environments in which our minds evolved. (...) As such, there was no single psychological type towards which evolution could gravitate. Instead we evolved a stable polymorphism of psychological types, maintained by frequency-dependent selection, each predisposed towards particular social and moral attitudes and behaviours. This can help explain the existence of moral diversity, particularly intra-cultural moral diversity, and seemingly intractable moral disagreement. (shrink)

On standard readings of Grice, Gricean communication requires (a) possession of a concept of belief, (b) the ability to make complex inferences about others’ goal-directed behaviour, and (c) the ability to entertain fourth order meta-representations. To the extent that these abilities are pre-requisites of Gricean communication they are inconsistent with the view that Gricean communication could play a role in their development. In this paper, I argue that a class of ‘minimally Gricean acts’ satisfy the intentional structure described by Grice, (...) but require none of abilities (a)-(c). As a result, Gricean communicative abilities may indeed contribute to the development of (a)-(c) – in particular, by enabling language development. This conclusion has important implications for our theorising about cognitive development. (shrink)

Nonreductive physicalism states that actions have sufficient physical causes and distinct mental causes. Nonreductive physicalism has recently faced the exclusion problem, according to which the single sufficient physical cause excludes the mental causes from causal efficacy. Autonomists respond by stating that while mental-to-physical causation fails, mental-to-mental causation persists. Several recent philosophers establish this autonomy result via similar models of causation :1031–1049, 2016; Zhong, J Philos 111:341–360, 2014). In this paper I argue that both of these autonomist models fail on account (...) of the problem of Edwards’s Dictum. However, I appeal to foundational principles of action theory to resuscitate mental-to-mental causation in a manner that is consistent with the models of causation endorsed by these autonomists.

Computer and information ethics, as well as other fields of applied ethics, need ethical theories which coherently unify deontological and consequentialist aspects of ethical analysis. The proposed theory of just consequentialism emphasizes consequences of policies within the constraints of justice. This makes just consequentialism a practical and theoretically sound approach to ethical problems of computer and information ethics.

Conscious states—state that there is something it is like to be in—seem both rich or full of detail and ineffable or hard to fully describe or recall. The problem of ineffability, in particular, is a longstanding issue in philosophy that partly motivates the explanatory gap: the belief that consciousness cannot be reduced to underlying physical processes. Here, we provide an information theoretic dynamical systems perspective on the richness and ineffability of consciousness. In our framework, the richness of conscious experience corresponds (...) to the amount of information in a conscious state and ineffability corresponds to the amount of information lost at different stages of processing. We describe how attractor dynamics in working memory would induce impoverished recollections of our original experiences, how the discrete symbolic nature of language is insufficient for describing the rich and high-dimensional structure of experiences, and how similarity in the cognitive function of two individuals relates to improved communicability of their experiences to each other. While our model may not settle all questions relating to the explanatory gap, it makes progress toward a fully physicalist explanation of the richness and ineffability of conscious experience—two important aspects that seem to be part of what makes qualitative character so puzzling.

There is a difference between having reasons for believing and believing for reasons. This difference is often fleshed out via an epistemic basing relation, where an epistemic basing relation obtains between beliefs and the actual reasons for which those beliefs are held. The precise nature of the basing relation is subject to much controversy, and one such underdeveloped issue is whether beliefs can be based on brain processing. In this paper I answer in the negative, providing reasons that the basing (...) relation must be a specific psychological level relation between mental states, rather than being a brain process.

It is sometimes claimed that Gricean communication is necessarily a form of cooperative or ‘joint’ action. A consequence of this Cooperative Communication View is that Gricean communication could not itself contribute to an explanation of the possibility of joint action. I argue that even though Gricean communication is often a form of joint action, it is not necessarily so—since it does not always require intentional action on the part of a hearer. Rejecting the Cooperative Communication View has attractive consequences for (...) our theorising about human cognitive development, since it opens up the possibility of appealing to communicative interaction to explain the emergence of joint action in phylogeny.

My topic is a certain view about mental images: namely, the ‘Multiple Use Thesis’. On this view, at least some mental image-types, individuated in terms of the sum total of their representational content, are potentially multifunctional: a given mental image-type, individuated as indicated, can serve in a variety of imaginative-event-types. As such, the presence of an image is insufficient to individuate the content of those imagination-events in which it may feature. This picture is argued for, or (more usually) just assumed (...) to be true, by Christopher Peacocke, Michael Martin, Paul Noordhof, Bernard Williams, Alan White, and Tyler Burge. It is also presupposed by more recent authors on imagination such as Amy Kind, Peter Kung and Neil Van Leeuwen. I reject various arguments for the Multiple Use Thesis, and conclude that instead we should endorse SINGLE: a single image-type, individuated in terms of the sum total of its intrinsic representational content, can serve in only one imagination event-type, whose content coincides exactly with its own, and is wholly determined by it. Plausibility aside, the interest of this thesis is also in its iconoclasm, as well as the challenge it poses for the diverse theories that rest on the truth of the Multiple Use Thesis. (shrink)

Libertarian free will is, roughly, the view that the same agential states can cause different possible actions. Nonreductive physicalism is, roughly, the view that mental states cause actions to occur, while these actions also have sufficient physical causes.

This paper concocts such a blend by articulating and defending, with some caveats, a nonreductive physicalist model of libertarian free will. (shrink)

Finally, in section 5 I take up the issues of whether I and Hegel do justice to the range of uses of conscience and whether or not the Hegelian view is too optimistic about modernity. (shrink)

Moss (2018) argues that rational agents are best thought of not as having degrees of belief in various propositions but as having beliefs in probabilistic contents, or probabilistic beliefs. Probabilistic contents are sets of probability functions. Probabilistic belief states, in turn, are modeled by sets of probabilistic contents, or sets of sets of probability functions. We argue that this Mossean framework is of considerable interest quite independently of its role in Moss’ account of probabilistic knowledge or her semantics for epistemic (...) modals and probability operators. It is an extremely general model of uncertainty. Indeed, it is at least as general and expressively powerful as every other current imprecise probability framework, including lower probabilities, lower previsions, sets of probabilities, sets of desirable gambles, and choice functions. In addition, we partially answer an important question that Moss leaves open, viz., why should rational agents have consistent probabilistic beliefs? We show that an important subclass of Mossean believers avoid Dutch bookability iff they have consistent probabilistic beliefs. (shrink)

This essay involves exploration of certain repercussions of Bernard Williams’ view that there is, in Wittgenstein’s later work, a transcendental idealism akin to that found in the Tractatus—sharing with it the feature that it cannot be satisfactorily stated. It is argued that, if Williams is right, then Wittgenstein’s later work precludes a philosophically substantial theory of meaning; for such a theory would force us to try to state the idealism. In a postscript written for the reprint of the essay, reasons (...) are given for thinking that Williams is not right: Wittgenstein’s later work actually helps us to repudiate as ill-conceived all those questions whose answers invite us to embrace any such idealism. But the main thesis of the essay remains intact. Indeed the idea that Wittgenstein’s later work precludes a philosophically substantial theory of meaning is reinforced. (shrink)

Nietzsche has been accused by Habermas of abandoning the pursuit of emancipation and truth. Ironically, this pursuit is at the core of Nietzsche’s works, though radically transformed. The pursuit of knowledge requires emancipated sovereign individuality, a severe honesty, and the courage to follow one's most rigorous use of reason and creative insight wherever they may lead, including the most disturbing insights about truth, language and reason themselves. The first part of this paper discusses Nietzsche’s ideas of individual sovereignty and the (...) associated ideas of emancipation and transformation necessary to this. The next section entitled The Question of Truth: Beyond Universalism and the Quest for Foundations and Certainty deals with how knowledge and truth are intelligible notions in the absence of certainty and absolute standards of truth. The following section, Nietzsche, Habermas and Social Solidarity shows how Habermas’s attempt to ground morality in his discourse ethics cannot succeed once the Nietzchean insight into truth is understood. In the final part, The Irony of Sovereign Individuality, I argue that morality is inconsistent with the individuality that it is supposed to uphold. Nietzsche’s ethical ideal provides a model for concrete individuality that offers the most powerful ethical contribution to social solidarity, given the failure of any grounded morality. (shrink)

In his recent book Bad Beliefs and Why They Happen to Good People, Neil Levy argues that conspiracy theories result from the same rational processes that underlie epistemic success.

We argue that social deference is an active process, and as such can be (...) helped or hindered by epistemic virtues and vices. With this in mind, holders of bad beliefs acquire more responsibility than is considered by Levy. (shrink)

Letheby’s book is an engaging and crystal-clear exploration of the philosophical issues raised by the use of psychedelic drugs. In this paper, we focus on the epistemological issues Letheby examines in chapter 8 and argue that his analysis requires an agency-first approach to epistemic evaluation. On an agency-first approach, epistemic evaluation is about identifying the skills agents needs to acquire in order to pursue and fulfil their epistemic goals.

An object-based correspondence theory of truth holds that a truth-bearer is true whenever its truth conditions are met by objects and their properties. In order to develop such a view, the principal task is to explain how truth-bearers become endowed with their truth conditions. Modern versions of the correspondence theory see this project as the synthesis of two theoretical endeavours: basic metasemantics and compositional semantics. Basic metasemantics is the theory of how simple, meaningful items (e.g. names and concepts) are endowed (...) with their contributions to truth conditions, and compositional semantics is the theory of how the meanings of simple items compose to generate (among other things) the truth conditions of sentences. Understanding truth along these broad lines was once popular; it was first championed by Field (1972). However, the once-popular conception of its tasks included an over-ambitious view of basic metasemantics. It was thought that reference needed to be analyzed (or reduced a posteriori) in terms of more fundamental, non-semantic relations (e.g. causal relations, indication, or teleological relations, in the case of mental representation). Obstacles in providing such an analysis engendered skepticism towards this understanding of truth and eventually gave way to its deflationary competitors. This dissertation aims to defend the modern, object-based correspondence theory against its rivals—especially deflationism. Chapter one provides a historically-grounded overview of the theory. Chapter two identifies two points of contrast between the correspondence theorist and the deflationist: they employ different orders of explanation for the variety of semantic phenomena, and they (traditionally) take different attitudes towards the prospects of reduction. Situating the dialectic in this way allows me to develop a middle ground: a moderate version of inflationism that takes the inflationary explanatory structure and combines it with a non-reductive, pluralist approach to basic metasemantics. Chapter three expands on the details of this pluralist account of reference. Chapter four contrasts the view with another rival approach to basic metasemantics: metasemantic interpretationism. And finally, chapter five applies the theory to answer another question of broad philosophical interest: what role does our conception of truth play in inquiry about the world? (shrink)

Tomasello and colleagues have offered various arguments to explain why apes find the comprehension of pointing difficult. They have argued that: (i) apes fail to understand communicative intentions; (ii) they fail to understand informative, cooperative communication, and (iii) they fail to track the common ground that pointing comprehension requires. In the course of a review of the literature on apes' production and comprehension of pointing, I reject (i) and (ii), and offer a qualified defence of (iii). Drawing on work on (...) expressive communication, I sketch an account of a mechanism by which ape gestural communication may proceed: the showing of expressive and naturally meaningful embodied behaviours. Such gestures are easily interpretable because they present rich evidence for a speaker's message. By contrast, pointing typically provides poor evidence for a speaker’s message, which must therefore be inferred from considerations in the interlocutors' common ground. This makes pointing comprehension comparatively difficult. (shrink)
