Qualitative evidence concerning the relationship between QoL and a wide range of disabilities suggests that subjective judgments regarding other people’s QoL are wrong more often than not and that such judgments by medical practitioners in particular can be biased. Guided by their desire to do good and avoid harm, surgeons often rely on "the eyeball test" to decide whether a patient will or will not benefit from surgery. But the eyeball test can easily harbor a range of implicit judgments and (...) biases against patients with disabilities, including erroneous assumptions about QoL. We critique the use of the "eyeball" test and offer suggestions to reduce bias and ensure that patients’ values are more consistently prioritized in surgical decision-making. (shrink)

After severe brain injury, one of the key challenges for medical doctors is to determine the patient’s prognosis. Who will do well? Who will not do well? Physicians need to know this, and families need to do this too, to address choices regarding the continuation of life supporting therapies. However, current prognostication methods are insufficient to provide a reliable prognosis. -/- Functional Magnetic Resonance Imaging (MRI) holds considerable promise for improving the accuracy of prognosis in acute brain injury patients. Nonetheless, (...) research on functional MRI in the intensive care unit context is ethically challenging. These studies raise several ethical issues that have not been addressed so far. In this article, Prof. Charles Weijer and his co-workers provide a framework for researchers and ethics committees to design and review these studies in an ethically sound way. (shrink)

Here I both celebrate and critique the legacy of Charles W. Mills. I begin by offering some reflections on the trajectory of Mills’s career and intellectual development, focusing on his move from Marxist philosophy to the philosophy of race. I then attempt to undermine an argument in Mills’s final book, for why those interested in emancipation should choose liberalism over Marxism. By contrasting Mills with the late Italian Marxist philosopher of history Domenico Losurdo, with whom Mills shared a blistering (...) critique of ‘racial’ liberalism but whom I claim Mills misread, I seek to weaken key premises in Mills’s argument. (shrink)

Charles Mills' philosophical position has undergone a number of subtle shifts over the past 30 years. Nevertheless, there has been a relative consistency in his thought over the past two decades, at least since The Racial Contract of 1997. That consistency consists in his turn towards social contract theory and its liberal values and away from Marxism with its focus on class and political economy. Mills notes that this turn does not constitute a “a complete repudiation of Marxism, since (...) I do think that a modified historical materialism might be able to carry out an adequate conceptualization of the significance of race.” Some of the claims Mills makes about Marx and Engels, however, should be challenged; they (or their views) are not as “white” as Mills attests. Indeed, Marx and Engels made a considerable start at theorizing white supremacy as an outgrowth of modern capitalism. (shrink)

In "Frailty Triage: Is Rationing Intensive Medical Treatment on the Grounds of Frailty Ethical?," Wilkinson (2021) argues that the use of frailty scores in ICU triage does not necessarily involve discrimination on the basis of disability. In support of this argument, he claims, “it is not the disability per se that the score is measuring – rather it is the underlying physiological and physical vulnerability." While we appreciate the attention Wilkinson explicitly pays to disability in this piece, we find the (...) distinction between disability and underlying vulnerability untenable both theoretically and practically. In this peer commentary, we begin with a brief overview of research in philosophy of disability concerning the meaning of the concept itself. We argue that this research demonstrates that many forms of disability do not involve underlying vulnerabilities, and, furthermore, that Wilkinson equivocates between "disability" understood as a medical category vs. "disability" understood as a feature of lived experience. We reject Wilkinson’s distinction on these grounds and offer further considerations to avoid disability discrimination in emergency and crisis standards of care contexts. (shrink)

This paper is a contribution to the long-standing debate over the coherence of Charles Sanders Peirce’s overall system of philosophy. It approaches that issue through the lens of a contemporary debate over the notion of metaphysical grounding, or more broadly, the nature of metaphysical explanation, employing the laws of logic as a case study. The central question concerns how we can take seriously what we shall call Peirce’s Rule—that nothing can be admitted to be absolutely inexplicable—without being vulnerable to (...) a vicious regress or equally vicious circularity. I first argue that in Peirce’s early work he offers a quietist conception of grounding that provides a persuasive and ground-breaking answer to this central question. I then raise a familiar concern, that in Peirce’s later work we find hints of a more metaphysical conception of grounding that seems unable to answer that question and is thus inconsistent with his earlier work. The paper ends with a speculative interpretation of Peirce’s approach to metaphysics and its possible role in grounding logical principles. (shrink)

Charles Sanders Peirce famously claimed that ‘The opinion which is fated to be ultimately agreed to by all who investigate is what we mean by the truth’ (W3: 273). Christopher Hookway has argued for a highly distinctive interpretation of this claim in terms of speech-acts and the normative commitments we incur in performing them. So-construed, Peirce’s conception of truth is difficult to compare with standard theories of the concept, which tend to focus instead upon some property or feature that (...) is shared by all and only true propositions, and with whether or not that property is substantive or metaphysically significant. This paper examines Hookway’s interpretation of Peirce’s conception of truth in an effort to clarify its position in logical space. It then raises some difficulties for the way Hookway tries to accommodate Peirce’s remarks about the special status of assertion and belief in science. (shrink)

In this comment on Misak’s Cambridge Pragmatism, I examine a case study—debate about the existence of free will—in order to explore residual tensions between Misak’s ‘truth-affirming,’ Peircean pragmatism, and mainstream analytic philosophy. I suggest that Misak’s Peirce makes a metaphysical commitment to the existence of rational self-control, and thereby to the existence of free will. I also suggest, however, that her ‘analytic pragmatism’ thus far offers few clues about how we should defend such a commitment from skeptical arguments emerging from (...) contemporary analytic metaphysics. I conclude that analytic pragmatists have more work to do in explaining pragmatism’s complex relationship with metaphysics, and defending its core commitments from skeptical threats. (shrink)

Communitarians like Alasdair MacIntyre, Charles Taylor, and Michael Sandel, defend what we may call the ‘social constitution thesis.’ This is the view that participation in society makes us what we are. This claim, however, is ambiguous. In an attempt to shed some light on it and to better understand the impact its truth would have on our beliefs regarding autonomy, I offer four possible ways it could be understood and four corresponding senses of individual independence and autonomy. I also (...) indicate what senses liberals can accept that we are socially constituted and in what sense I take communitarians to argue we are socially constituted. (shrink)

Critics of liberalism in the past two decades have argued that the fact that we are necessarily "situated" or "embedded" means that we can not always choose our own ends (for example, our conceptions of the good or our loyalties to others). Some suggest that we simply discover ourselves with these "connections." If correct, this would argue against (Rawlsian) hypothetical contract models and liberalism more broadly, make true impartiality impossible, and give support to traditionalist views like those of Alasdair MacIntyre, (...) Charles Taylor, and Michael Sandel. These same critics argue that liberalism's rejection or neglect of this supposed fact of our moral life has pernicious anti-social affects. I argue that the critics are wrong in both cases, defending what I call "strong voluntarism." In contrast both to recent critics of liberalism and the dominant trend in recent liberal thought, my defense of strong voluntarism allows that we can always choose to accept or reject any end we happen to have but that this does not lead to any pernicious anti-social effects.

Critics of liberalism have argued that liberal individualismmisdescribes persons in ignoring the degree to which they aredependent on their communities. Indeed, they argue that personsare essentially socially constituted. In this paper, however, Iprovide two arguments – the first concerning communitariandescriptive claims about persons, our society, and the communitarian ideal society, and the second regarding thecommunitarian view of individual autonomy – that the communitariantheory of Alasdair MacIntyre, Charles Taylor, and Michael Sandel,relies on individuals either being independent from theircommunities or having (...) a community-independent desire. Thisis indicative of a deep contradiction in communitarian thought. (shrink)

Pavel Tichy (1936-1994) was a Czech philosopher who originally studied and worked at Charles University in Prague, and spent the second half of his life in New Zealand as a political refugee. Early in his career he invented intensional logic, simultaneously with Richard Montague, but published his version in 1971, slightly after Montague's 1970 papers, and has never been recognised for this achievement. But this was only the beginning of his work. He developed a highly original theory of semantics (...) called Transparent Intensional Logic, which is the basis of an important research program based in the Czech Republic and Slovenia. He published a wide range of original work in semantics, philosophy of logic and language, philosophy of science, and metaphysics; but despite the indisputable quality of this work, he has gained little contemporary recognition. This article provides a brief introduction to his work, focussing mainly on basic ideas of his intensional semantics and his theory of 'constructions'. (shrink)

Charles Sanders Peirce has commonly been interpreted as a proponent of an epistemic theory of truth. Such a theory has the apparent advantage of directly undercutting radical skepticism, but the disadvantage of implausibly entailing that there are no truths concerning irretrievably lost facts. Recently Andrew Howat has defended Peirce’s epistemic constraint on truth by recasting Peirce’s claim that all truths would be believed following sufficient inquiry, not as constitutive of truth, but as a Wittgensteinian hinge proposition. I begin (...) with a twofold historical reply to Howat: first, Peirce can at least plausibly be read as claiming that the claim in question is analytic of the concept <truth>; and second, while Peirce did think we must accept without evidence the further claim that there are any truths (so characterized), he regarded this further claim not as a Wittgensteinian hinge but as a reasonable hope. I then substantively defend the latter Peircean proposal, arguing that hopes, as against beliefs, are chiefly warranted pragmatically, and so can be warranted even to a sufficient level to render them properly action-guiding in cases where belief in the same proposition would remain unjustified. I conclude by suggesting, first, that this proposal is superior to Wittgenstein’s own epistemology in evading psychologism, and second, that it attractively vindicates the reasonableness of inquiry on Peircean grounds that don’t require an appeal to an implausible epistemic theory of truth.

According to Quine, Charles Parsons, Mark Steiner, and others, Russell’s logicist project is important because, if successful, it would show that mathematical theorems possess desirable epistemic properties often attributed to logical theorems, such as aprioricity, necessity, and certainty. Unfortunately, Russell never attributed such importance to logicism, and such a thesis contradicts Russell’s explicitly stated views on the relationship between logic and mathematics. This raises the question: what did Russell understand to be the philosophical importance of logicism? Building on recent (...) work by Andrew Irvine and Martin Godwyn, I argue that Russell thought a systematic reduction of mathematics increases the certainty of known mathematical theorems (even basic arithmetical facts) by showing mathematical knowledge to be coherently organized. The paper outlines Russell’s theory of coherence, and discusses its relevance to logicism and the certainty attributed to mathematics. (shrink)

In this essay, I evaluate four central metaethical readings of Spinoza’s moral philosophy in the literature: unqualified anti-realism, qualified anti-realism, qualified realism, and unqualified realism. More specifically, I discuss the metaethical readings of Charles Jarrett (unqualified anti-realism), Matthew Kisner (qualified anti-realism), Jon Miller (qualified realism), and Andrew Youpa (unqualified realism), each of which captures core aspects of this debate. My conclusions are that (1) Spinoza is neither an unqualified anti-realist nor an unqualified realist and (2) Spinoza’s ethical framework (...) represents a qualified synthesis of realist (naturalistic) and anti-realist (affective) features.

Many philosophers have thought that our folk, or pre-reflective, view of persistence is one on which objects endure. This assumption not only plays a role in disputes about the nature of persistence itself, but is also put to use in several other areas of metaphysics, including debates about the nature of change and temporal passage. In this paper, we empirically test three broad claims. First, that most people (i.e. most non-philosophers) believe that, and it seems to them as though, objects (...) persist by enduring rather than perduring. Second, that most people have a view of change on which enduring but not perduring objects count as changing. Third, that one reason why the folk represent time as dynamical is because it seems to them, and they believe that, they endure through time. We found no evidence to support these claims. While there are certainly plenty of ‘folk’ endurantists in the population we tested, there are also plenty of ‘folk’ perdurantists. We did not find robust evidence that a majority of people believed that, or it seemed to them as though, objects endure rather than perdure. We conclude that many arguments in favour of endurantism that appeal to folk beliefs about, or experiences of, persisting objects and change rest on views about those beliefs and experiences that are empirically unsupported. There is no evidence to suggest that endurantism is the folk friendly view of persistence, and so we should stop treating it as such without argument. (shrink)

This paper aims to determine whether we can locate temporal passage in a non-dynamical (block universe) world. In particular, we seek to determine both whether temporal passage can be located somewhere in our world if it is non-dynamical, and also to home in on where in such a world temporal passage can be located, if it can be located anywhere. We investigate this question by seeking to determine, across three experiments, whether the folk concept of temporal passage can be satisfied (...) in our world if it is non-dynamical, and, if it can, what sort of thing in our world satisfies that concept. In particular, we focus on the question of whether that concept (if satisfied) is satisfied by something mind-dependent or something mind-independent. In other words, we ask, is temporal passage something that is at least partially in the mind, or is it entirely external to the mind? We find, contrary to what is often assumed by dynamists and non-dynamists alike, that the folk concept of temporal passage is satisfied in our world conditional on it being non-dynamical, and that the concept is satisfied by something mind-independent. This provides further ammunition for recent deflationary accounts of temporal passage that attempt to locate passage somewhere in our non-dynamical world. (shrink)

Conspiracy theories should be neither believed nor investigated - that is the conventional wisdom. I argue that it is sometimes permissible both to investigate and to believe. Hence this is a dispute in the ethics of belief. I defend epistemic ‘oughts’ that apply in the first instance to belief-forming strategies that are partly under our control. I argue that the policy of systematically doubting or disbelieving conspiracy theories would be both a political disaster and the epistemic equivalent of self-mutilation, since (...) it leads to the conclusion that history is bunk and the nightly news unbelievable. In fact (of course) the policy is not employed systematically but is only wheeled on to do down theories that the speaker happens to dislike. I develop a deductive argument from hard-to-deny premises that if you are not a ‘conspiracy theorist’ in my anodyne sense of the word then you are an ‘idiot’ in the Greek sense of the word, that is, someone so politically purblind as to have no opinions about either history or public affairs. The conventional wisdom can only be saved (if at all) if ‘conspiracy theory’ is given a slanted definition. I discuss some slanted definitions apparently presupposed by proponents of the conventional wisdom (including, amongst others, Tony Blair) and conclude that even with these definitions the conventional wisdom comes out as deeply unwise. I finish up with a little harmless fun at the expense of David Aaronvitch whose abilities as a rhetorician and a popular historian are not perhaps matched by a corresponding capacity for logical thought.

Future-biased individuals systematically prefer pleasures to be in the future and pains to be in the past. Empirical research shows that negative future-bias is robust: people prefer more past pain to less future pain. Is positive future-bias robust or fragile? Do people only prefer pleasures to be located in the future, compared to the past, when those pleasures are of equal value, or do they continue to prefer that pleasures be located in the future even when past pleasures outweigh future (...) ones? Some arguments against the rationality of future-bias require positive future-bias to be robust, while others require it to be fragile. We empirically investigate and show that positive future-bias is robust. (shrink)

Future-bias is the preference, all else being equal, for positive states of affairs to be located in the future not the past, and for negative states of affairs to be located in the past not the future. Three explanations for future-bias have been posited: the temporal metaphysics explanation, the practical irrelevance explanation, and the three mechanisms explanation. Understanding what explains future-bias is important not only for better understanding the phenomenon itself, but also because many philosophers think that which explanation is (...) the correct one has implications for our evaluation of the normative status of future-bias. In this paper we focus on the connection between future-bias and the temporal value asymmetry. The latter refers to the fact that people tend to assign more value to a state of affairs when it is located in the future, as opposed to being equidistant in the past. All three candidate explanations offered for future-bias proceed by explaining the temporal value asymmetry, and then supposing that future-bias is simply a manifestation of that asymmetry. Recently, however, it has been argued that the conditions under which people display the temporal value asymmetry and future-bias are different, and that this is reason to doubt that the latter is a manifestation of the former. In this paper we empirically test one response to this argument against the manifestation thesis—the simulation response—according to which once we control for the degree to which people can simulate the object of their preference, we find that people display future-bias and the temporal value asymmetry in the same conditions. We find no evidence in favour of the simulation response. Moreover, our results support some previous research that suggests that the temporal value asymmetry is less robust than previously thought, and this in itself casts doubt on the idea that future bias is just a manifestation of this asymmetry.

This paper empirically investigates whether people’s implicit decision theory is more like causal decision theory or more like a non-causal decision theory (such as evidential decision theory). We also aim to determine whether implicit causalists, without prompting and without prior education, make a distinction that is crucial to causal decision theorists: preferring something _as a news item_ and preferring it _as an object of choice_. Finally, we investigate whether differences in people’s implicit decision theory correlate with differences in their level (...) of _future bias_: the preference for positively valenced events to be located in the future and not the past, and negatively valenced events to be located in the past and not the future. We find that people are overwhelmingly non-causalists. We also find that implicit causalists _do not_ make the distinction between news items and objects of choice, and that there is little to no correlation between people’s future bias and their implicit decision theory. We end by discussing the philosophical upshots of this work. (shrink)

Several philosophers have suggested that certain aspects of people’s experience of agency partly explains why people tend to report that it seems to them, in perceptual experience, as though time robustly passes. In turn, it has been suggested that people come to believe that time robustly passes on the basis of its seeming to them in experience that it does. We argue that what require explaining is not just that people report that it seems to them as though time robustly (...) passes, and that they believe that it does, but rather, the substantial variation (a) in people’s reports regarding whether it seems as though time robustly passes, and (b) their beliefs about whether time robustly passes. We empirically investigate the agentive explanation of (a), according to which variation in people’s agentive experiences explains variation in people’s reports regarding whether it seems to them as though time robustly passes. We also empirically investigate the experiential seeming explanation of belief, according to which variation in people’s beliefs about whether time robustly passes is explained by variation in their reports regarding whether it seems in experience as though time robustly passes. We found empirical support for the agentive explanation, but not for the experiential seeming explanation of passage beliefs. We consider the implications of our results for three views about temporal experience and temporal beliefs: dynamism, passage illusionism and deflationism. (shrink)

While philosophical questions about health and disease have attracted much attention in recent decades, and while opinions are divided on most issues, influential accounts seem to embrace negativism about health, according to which health is the absence of disease. Some subscribe to unrestricted negativism, which claims that negativism applies not only to the concepts of health and disease as used by healthcare professionals but also to the lay concept that underpins everyday thinking. Whether people conceptualize health in this manner has (...) implications for medical care and public health, and so we set out to examine this claim in two studies. Participants were asked to assess and compare the health states of two people presented in two vignettes. We found that both lay people and medical students conceptualize health as something more than the absence of disease. We argue that our findings highlight a need to rethink unrestricted negativism and indicate a need to rethink the way the debate has traditionally focused on disease. (shrink)

Empirical evidence shows that people have multiple time-biases. One is near-bias, another is future-bias, and a third is present-bias. Philosophers are concerned with the normative status of these time-biases. They have argued that, at least in part, the normative status of these biases depends on the extent to which they tend to promote, or frustrate, wellbeing, where “wellbeing” is taken to be of fundamental value. Since near-bias is thought to be associated with impulsivity, lack of self-control, and poor long-term health (...) and financial outcomes, it has often been supposed that it is associated with lower wellbeing. On those grounds, philosophers have argued that near-bias is rationally impermissible. By contrast, philosophical views about the normative status of future-bias have been mixed, with some arguing that future-bias is impermissible because, they think, it frustrates wellbeing, and others arguing that it is at least permissible (and perhaps obligatory) because it is the product of mechanisms whose functioning can be expected to promote wellbeing. However, to date there are no studies that have directly probed how time-biases correlate with wellbeing. Since it's not a settled matter which psychological mechanisms underlie time-biases, it is not uncontroversial which things serve as proxies for these preferences. We directly empirically investigate the connection between time-biases and measures of wellbeing, to see which of these biases is associated with promoting, or frustrating wellbeing. Contrary to expectation, we found no evidence that near-bias or present-bias are associated with frustrating wellbeing on any of the constructs we measured. On the other hand, and contrary to what some philosophers have supposed, we found that future-bias was associated with higher measures of wellbeing on several measures. We consider the implications of these findings for the evaluation of the normative status of these time biases. (shrink)

With the recent renewed interest in AI, the field has made substantial advancements, particularly in generative systems. Increased computational power and the availability of very large datasets has enabled systems such as ChatGPT to effectively replicate aspects of human social interactions, such as verbal communication, thus bringing about profound changes in society. In this paper, we explain that the arrival of generative AI systems marks a shift from ‘interacting through’ to ‘interacting with’ technologies and calls for a reconceptualization of socio-technical (...) systems as we currently understand them. We dub this new generation of socio-technical systems synthetic to signal the increased interactions between human and artificial agents, and, in the footsteps of philosophers of information, we cash out agency in terms of ‘poiêsis’. We close the paper with a discussion of the potential policy implications of synthetic socio-technical system. -/- . (shrink)

It’s generally thought that we naively or pre-theoretically represent the future to be open. While philosophers have modelled future openness in different ways, it’s unclear which, if any, captures our naïve sense that the future is open. In this paper we focus on just one way the future might count as being open: by being nomically open, and empirically investigate whether our naïve representation of the future as open is partly constituted by representing the future as nomically open. We also (...) investigate the connection between our naïve representation of the future as open, and our representation of time. One of the purported advantages of the growing block theory of time is that it captures our naive sense that the future is open, and the past closed. We investigate whether there is an explanatory connection between people representing the future to be nomically open and representing our world to be a growing block and reflect on the implications of our findings for theorising about future openness and temporal ontology.

How do people understand the concepts of mental health and disorder? The objective of this paper is to examine the impact of several factors on people’s judgments about whether a condition constitutes a mental disorder or a healthy state. Specifically, this study examines the impact of the source of the condition, its outcome, individual valuation (i.e., the value the individual attaches to the condition), and group valuation (i.e., the value the relevant group attaches to the condition). While we find that (...) people’s health and disorder judgments are driven by perceived dysfunction, we also find that health and disorder judgments are impacted differently by these factors. Health judgements are impacted by outcome and individual valuation, and disorder judgments are impacted by condition source. These results suggest that the folk concept of mental health is positive (i.e., mental health is more than the absence of mental disorder) and normativist (i.e., value judgments play a significant role in determining whether a condition counts as healthy), while the concept of mental disorder aligns with a naturalist perspective, at least to the extent that dysfunction plays an important role in categorizing a condition as a disorder. However, our finding that people’s dysfunction judgments are influenced by individual valuation and outcomes poses a strong challenge to naturalist accounts. To provide access to our supplementary data, an appendix has been included. (shrink)

We explore the role of episodic imagining in explaining why people both differentially report that it seems to them in experience as though time robustly passes, and why they differentially report that they believe that time does in fact robustly pass. We empirically investigate two hypotheses, the differential vividness hypothesis, and the mental time travel hypothesis. According to each of these, the degree to which people vividly episodically imagine past/future states of affairs influences their tendency to report that it seems (...) to them as though time robustly passes and to judge that time does robustly pass. According to the former, a greater degree of vividness will tend to increase the extent to which people make such reports, while according to the latter, it will tend to decrease the extent to which people make such reports. We found weak evidence in favour of the former hypothesis. We reflect on the implications of this finding for theorising about such reports. (shrink)

I propose a construal of aesthetic value that gives us reason to emphasize some aesthetic practices over others. This construal rests on the existence of a central aesthetic value, namely apprehension-testing intricacy within an appropriate domain. I address three objections: the objection that asks how an aesthetic value based on intricacy can account for the value of minimalism; the objection that asks about the difference between intricacy within a medium and intricacy between media; and the objection that asks about the (...) danger of a regress. I then say that, although this central aesthetic value can in principle allow us to adjudicate between aesthetic practices, we have epistemic limits (about the potential of certain artistic domains to allow for apprehension-testing intricacy) that prevent adjudication in some cases. Even if there is a difference between the vastness of the potential-intricacy-fields somewhere down the line, it is too far for us to see. (shrink)

The sentence "The boss fired the employee who is always late" invites the defeasible inference that the speaker is attempting to convey that the lateness caused the firing. We argue that such inferences cannot be understood in terms of familiar approaches to extrasemantic enrichment such as implicature, impliciture, explicature, or species of local enrichment already in the literature. Rather, we propose that they arise from more basic cognitive strategies, grounded in processes of coherence establishment, that thinkers use to make sense (...) of the world. Attention to such cases provides a richer and more varied landscape of extrasemantic enrichment than has been appreciated to date. (shrink)

According to the truthmaker theory that we favour, all contingent truths are made true by existing facts or states of affairs. But if that is so, then it appears that we must accept the existence of the negative facts that are required to make negative truths (such as 'There is no hippopotamus in the room.') true. We deny the existence of negative facts, show how negative truths are made true by positive facts, point out where the (reluctant) advocates of negative (...) facts (Russell, Armstrong, et al.) went wrong, and demonstrate the superiority of our solution to the alternatives.

Epistemic instrumentalism views epistemic norms and epistemic normativity as essentially involving the instrumental relation between means and ends. It construes notions like epistemic normativity, norms, and rationality, as forms of instrumental or means-end normativity, norms, and rationality. I do two main things in this paper. In part 1, I argue that there is an under-appreciated distinction between two independent types of epistemic instrumentalism. These are instrumentalism about epistemic norms and instrumentalism about epistemic normativity. In part 2, I argue that this (...) under-appreciated distinction matters for the debate surrounding the plausibility of EI. Specifically, whether we interpret EI as norm-EI or as source-EI matters for the widely discussed universality or categoricity objection to EI, and for two important motivations for adopting EI, namely naturalism and the practical utility of epistemic norms. I will then conclude by drawing some lessons for epistemic instrumentalism going forward. (shrink)

Lee (2017) calls for greater attention to the shared epistemological and normative grounds of both public health ethics and environmental ethics, and to Potter’s original conception of bioethics, which, as she rightly observes, has been largely disregarded in contemporary North American bioethics scholarship and practice. In a previous publication we also argued in favor of reviving the Potterian approach to bioethics; we built a case grounded in “the relatively new field of molecular epigenetics [that] provides novel information that should serve (...) as additional justification for expanding the scope of bioethics to include environmental and public health concerns.”.

This paper presents an attempt to integrate theories of causal processes—of the kind developed by Wesley Salmon and Phil Dowe—into a theory of causal models using Bayesian networks. We suggest that arcs in causal models must correspond to possible causal processes. Moreover, we suggest that when processes are rendered physically impossible by what occurs on distinct paths, the original model must be restricted by removing the relevant arc. These two techniques suffice to explain cases of late preëmption and other cases (...) that have proved problematic for causal models. (shrink)

This paper formalizes part of the cognitive architecture that Kant develops in the Critique of Pure Reason. The central Kantian notion that we formalize is the rule. As we interpret Kant, a rule is not a declarative conditional stating what would be true if such and such conditions hold. Rather, a Kantian rule is a general procedure, represented by a conditional imperative or permissive, indicating which acts must or may be performed, given certain acts that are already being performed. These (...) acts are not propositions; they do not have truth-values. Our formalization is related to the input/ output logics, a family of logics designed to capture relations between elements that need not have truth-values. In this paper, we introduce KL3 as a formalization of Kant’s conception of rules as conditional imperatives and permissives. We explain how it differs from standard input/output logics, geometric logic, and first-order logic, as well as how it translates natural language sentences not well captured by first-order logic. Finally, we show how the various distinctions in Kant’s much-maligned Table of Judgements emerge as the most natural way of dividing up the various types and sub-types of rule in KL3. Our analysis sheds new light on the way in which normative notions play a fundamental role in the conception of logic at the heart of Kant’s theoretical philosophy. (shrink)

Denying the conclusion of a valid argument is not generally permissible if one suspends on one premise of the argument and believes the other premise. This can happen when one’s only critique of an argument is to undermine one premise. There is incoherence there. Here I examine how this is relevant to the debate on evolutionary debunking of our moral knowledge. I argue that one significant line of response to the debunker is unsuccessful: merely undermining the debunker’s empirical claim. It (...) is not rational to respond this way and believe one has moral knowledge. First I present evidence that prominent critics of the debunking argument merely undermine the debunker’s empirical claim. Then I argue for two premises: merely undermining a premise can only justify a middling amount of doubt towards the premise and we should have no more doubt about the conclusion of a valid argument than we do about the premises. Implications of the argument are explored. (shrink)

I argue that No-Ought-From-Is (in the sense that I believe it) is a relatively trivial affair. Of course, when people try to derive substantive or non-vacuous moral conclusions from non-moral premises, they are making a mistake. But No-Non-Vacuous-Ought-From-Is is meta-ethically inert. It tells us nothing about the nature of the moral concepts. It neither refutes naturalism nor supports non-cognitivism. And this is not very surprising since it is merely an instance of an updated version of the conservativeness of logic (in (...) a logically valid inference you don’t get out what you haven’t put in): so long as the expressions F are non-logical, you cannot get non-vacuous F-conclusions from non-F premises. However, the triviality of No-Non-Vacuous-Ought-From-Is is important and its non-profundity profound. No-Ought-From-Is is widely supposed to tell us something significant about the nature of the moral concepts. If, in fact, it tells us nothing, this is a point well worth shouting from the housetops. This brings me to my dispute with Gerhard Schurz who has proved a related version of No-Ought-From-Is, No-Ought-Relevant-Ought-From-Is, a proof which relaxes my assumption that ‘ought’ should not be treated as a logical constant. But if ought is not a logical expression then it does not really matter much that No-Ought-From-Is would be salvageable even if it were. Furthermore, Schurz’s proof depends on special features of the moral concepts and this might afford the basis for an abductive argument to something like non-cognitivism. As an error theorist, and therefore a cognitivist, I object. Finally I take a dim view of deontic logic. Many of its leading principles are false, bordering on the nonsensical, and even the reasonably plausible ones are subject to devastating counter-examples. (shrink)

The eminent French biologist and historian of biology, François Jacob, once notoriously declared “On n’interroge plus la vie dans les laboratoires”: laboratory research no longer inquires into the notion of ‘Life’. Nowadays, as David Hull puts it, “both scientists and philosophers take ontological reduction for granted… Organisms are ‘nothing but’ atoms, and that is that.” In the mid-twentieth century, from the immediate post-war period to the late 1960s, French philosophers of science such as Georges Canguilhem, Raymond Ruyer and Gilbert Simondon (...) returned to Jacob’s statement with an odd kind of pathos: they were determined to reverse course. Not by imposing a different kind of research program in laboratories, but by an unusual combination of historical and philosophical inquiry into the foundations of the life sciences (particularly medicine, physiology and the cluster of activities that were termed ‘biology’ in the early 1800s). Even in as straightforwardly scholarly a work as La formation du concept de réflexe aux XVIIe et XVIIIe siècles (1955), Canguilhem speaks oddly of “defending vitalist biology,” and declares that Life cannot be grasped by logic (or at least, “la vie déconcerte la logique”). Was all this historical and philosophical work merely a reassertion of ‘mysterian’, magical vitalism? In order to answer this question we need to achieve some perspective on Canguilhem’s ‘vitalism’, notably with respect to its philosophical influences such as Kurt Goldstein. (shrink)

This implementation framework bridges the theoretical concepts of the Instructional Modular Approach with the practical development of Science Teaching Competency. It offers prospective teachers a structured, adaptive, and technology-enhanced pathway to becoming competent and innovative science educators. Each unit is meticulously designed to not only equip teachers with theoretical knowledge but also to hone their practical skills and competencies essential for a dynamic science teaching environment.

The situated potentials for action between material things in the world and the interactional processes thereby afforded need to be seen as not only constituting the possibility of agency, but thereby also comprising it. Eo ipso, agency must be de-fused from any local, "contained" subject and be understood as a situational property in which subjects and objects can both participate. Any technological artifact should thus be understood as a complex of agential capacities that function relative to any number of social (...) and material factors. Keeping in mind that we are co-constituted by webs of relations involving increasingly complex collections of artefacts, networks, niches, and communities of practice, our investigation will be guided by interrogating the functional potential of a thing that in the last fifteen years has seamlessly worked its way into the everyday life of millions of human agents. This "thing," the smartphone, is merely a nodal point in a highly complex network. Recognizing this massive "collective," we nevertheless want to show some of the ways in which something as seemingly mundane as a smartphone can reflexively alter the range of actions available to a cognitive agent (Latour 1994). Specifically, we hope to shed light on some of the social-cognitive consequences of technological mediation by looking at the complementary, if not mutually implied, domains of memory and knowledge.

We argue that the asymmetry between diverging and converging electromagnetic waves is just one of many asymmetries in observed phenomena that can be explained by a past hypothesis and statistical postulate (together assigning probabilities to different states of matter and field in the early universe). The arrow of electromagnetic radiation is thus absorbed into a broader account of temporal asymmetries in nature. We give an accessible introduction to the problem of explaining the arrow of radiation and compare our preferred strategy (...) for explaining the arrow to three alternatives: (i) modifying the laws of electromagnetism by adding a radiation condition requiring that electromagnetic fields always be attributable to past sources, (ii) removing electromagnetic fields and having particles interact directly with one another through retarded action-at-a-distance, (iii) adopting the Wheeler-Feynman approach and having particles interact directly through half-retarded half-advanced action-at-a-distance. In addition to the asymmetry between diverging and converging waves, we also consider the related asymmetry of radiation reaction. (shrink)

Many philosophers have adopted epistemic expressivism in recent years. The core commitment of epistemic expressivism is that epistemic claims express conative states. This paper assesses the plausibility of this commitment. First, we raise a new type of problem for epistemic expressivism, the epistemic motivation problem. The problem arises because epistemic expressivists must provide an account of the motivational force of epistemic judgment (the mental state expressed by an epistemic claim), yet various features of our mental economy seem to show that (...) they can’t do so. Second, we develop what we take to be the most promising response to that problem for expressivists. We end by noting that this response faces an important challenge pertaining to the psychology of epistemic criticism and praise. (shrink)

This dissertation explores how antiquity and some of its early modern admirers understand the notion of certainty, especially as it is theorized in Quintilian's Institutio Oratoria, a first-century educational manual for the aspiring orator that defines certainty in terms of consensus. As part of a larger discussion of argumentative strategies, Quintilian turns to the “nature of all arguments,” which he defines as “reasoning which lends credence to what is doubtful by means of what is certain” (ratio per ea quae certa (...) sunt fidem dubiis adferens: quae natura est omnium argumentorum, V.10.8). These certainties, he later specifies, include not matters of scientific demonstration or objective fact, but the agreements of various communities: the laws of cities, local customs, and other forms of consensus. As the foundation of persuasive rhetoric, these consensus-based certainties situate argumentation as the practice of crafting agreements rather than demonstrating necessary conclusions. Taking as its point of departure Quintilian's novel understanding of certainty, this study looks to some of Quintilian's intellectual forebears as well as his later readers to show how his work is both a nexus of earlier intellectual developments as well as an important inspiration for later accounts of certainty, even into the early modern period. After illustrating in the first chapters of this dissertation how Quintilian's manual incorporates elements from Aristotelian notions of dialectic and rhetoric as well as from Ciceronian skeptical approaches to epistemology, I show how Quintilian's curriculum for the orator shapes the thought of Italian humanists, especially that of Lorenzo Valla (1406–1457), a reformer of scholastic logic and dialectic, and Giambattista Vico (1668–1744), an influential Neapolitan jurist. Adopting Quintilian's rendering of certainty as a matter of agreements and conventions, these later authors elaborate their own novel approaches to various fields—including law, language, and logic—through this ancient understanding of certum. Contrary to modern notions of certainty as objective or scientific fact, Quintilian's humanist readers continue to root this concept in consensus, both within the courtroom and without. (shrink)

This is a concordance of page numbers in the following editions of Merleau-Ponty's Phenomenology of Perception: English editions prior to the Routledge Classics 2002; Routledge Classics edition, with the new pagination; the French edition from Gallimard, prior to 2005; the 2e edition from Gallimard, 2005, with new pagination.

ABSTRACT Lewtas [2017] recently articulated an argument claiming that emergent conscious causal powers are impossible. In developing his argument, Lewtas makes several assumptions about emergence, phenomenal consciousness, categorical properties, and causation. We argue that there are plausible alternatives to these assumptions. Thus, the proponent of emergent conscious causal powers can escape Lewtas’s challenge.

This is a commentary on Adrian Heathcote’s interesting paper ‘Hume’s Master Argument’. Heathcote contends that No-Ought-From-Is is primarily a logical thesis, a ban on Is/Ought inferences which Hume derives from the logic of Ockham. NOFI is thus a variation on what Heathcote calls ‘Hume’s Master Argument’, which he also deploys to prove that conclusions about the future (and therefore a-temporal generalizations) cannot be derived by reason from premises about the past, and that conclusions about external objects or other minds cannot (...) be derived by reason from premises about impressions. Heathcote raises an important question. Having (apparently) argued that our inductive inferences are not justified by reason, Hume puts them down to Custom, and seems to suggest that we OUGHT to indulge this propensity but NOt the superstitious propensities that lead to religious belief. (Query: Why is it right to indulge one non-rational propensity but not the others?) Finally Heathcote argues that just as there are valid, but not formally valid, arguments taking us from claims about inferential relations to claims about what we ought to believe, so there may be valid, but not formally valid, arguments taking us from factual claims about some situation to claims about what we ought to do. -/- I reply that Hume does indeed have a Master Argument and that it does rely on logical principles but not on the logic of Ockham which had been largely forgotten by Hume’s day. Instead Hume relies on the idea widely believed in the 18th Century and taught to Hume at Edinburgh by his logic Professor Colin Drummond, that in a logically valid argument the conclusion is contained in the premises. I reconstruct Hume’s Master Argument using this principle. I draw a careful distinction between two theses: 1) that we cannot get from non-moral premises to moral conclusions with the aid of logic alone and 2) that we cannot get from non-moral premises to moral conclusions with aid of analytic bridge principles. Hume believed the first but not the second. What then is the role of NOFI in the larger argument of the Treatise? To show that the truths of ethics cannot be derived via logic from self-evident truths of some other kind and thus that they are not demonstrable. How can we make sense of Hume’s apparent belief that it is sometimes right to transcend reason and sometimes not? In the case of Custom, we live in a world governed by causal regularities, and, in such a world, induction is in fact a fairly reliable belief-forming mechanism. Thus a suitably qualified spectator (one aware of the kind of world we live in) would tend to approve of indulging it, even if it cannot be justified by reason. However, our superstitious propensities are (and can be known to be) unreliable, since they produce different and inconsistent results in different people. Thus it is it is wrong (something a suitably qualified spectator would disapprove of) to indulge the faculty of Superstition. I also take issue with Heathcote’s penchant for valid, but not formally valid, inferences. I supply the missing premises for Heathcote’s Is/Ought inferences and argue that they are either not true or not necessary. (shrink)
