The protection of species ranks highly among environmentalist priorities, and many environmentalists expect the public to respect and support efforts to protect and rehabilitate endangered species. There are a range of instrumental and anthropocentric justifications for these attitudes, yet some environmentalists want more. It is unclear that more is to be had. In particular, it is challenging to justify some environmentalist attitudes without appealing to some version of the claim that species are intrinsically valuable. However, this has been a notoriously (...) difficult thesis to defend, and it is clearly not available to those who doubt the existence of species. In this paper, I show how a number of environmentalist commitments that appear to be about the value of species can be interpreted and defended in a way that is compatible with antirealism about species. According to my proposal, the proper target of environmentalists’ evaluative concern is the irreplaceable design that is embodied by the individuals that make up a (putative) species. This approach can capture and justify many environmentalist attitudes about the value of biological variety without attributing intrinsic value to species, or even requiring a place for species in our ontology. This enables environmentalists to effectively sidestep a number of puzzling issues surrounding the nature and value of species. (shrink)

While Richard Joyce’s moral skepticism might seem to be an extreme metaethical view, it is actually far more moderate than it might first appear. By articulating four challenges facing his approach to moral skepticism, I argue that Joyce’s moderation is, in fact, a theoretical liability. First, the fact that Joyce is not skeptical about normativity in general makes it possible to develop close approximations to morality, lending support to moderate moral revisionism over moral error theory. Second, Joyce relies on strong, (...) contentious conceptual and empirical claims in support of his views. Third, Joyce’s evolutionary debunking argument threatens to backfire, generalizing to all normative judgments. Finally, Joyce fails to offer an adequate account of the normativity of desire. Each of these four challenges can be either sidestepped or embraced by radicalizing and defending a global form of normative skepticism. There are thus several ways in which global normative skepticism appears to be in a more robust dialectical position than Joyce’s moral skepticism. Furthermore, I argue, Joyce’s arguments against global normative skepticism are unconvincing. While this discussion is framed in terms of Joyce’s work, its arguments will apply to other moral skeptics who are not also global normative skeptics. The result is an invitation for Joyce and other moral skeptics to leave these problems behind and join the radical camp. (shrink)

David Enoch has recently proposed that the deliberative indispensability of irreducibly normative facts suffices to support their inclusion in our ontology, even if they are not necessary for the explanation of any observable phenomena. He challenges dissenters to point to a relevant asymmetry between explanation and deliberation that shows why explanatory indispensability, but not deliberative indispensability, is a legitimate guide to ontology. In this paper, I aim to do just that. Given that an entity figures in the actual explanation of (...) some phenomenon, it is not an open question whether that entity exists. Thus, if you can manage to find actual explanations, you can find answers to ontological questions. In contrast, even if some entity is indispensable to deliberation, it still might not exist. For example, even if some form of libertarian free will is deliberatively indispensable, we still might not have libertarian free will. So even if you manage to discover the indispensable commitments of deliberation, there is still more work to do to get to the bottom of things. That additional work is explanatory work, and so deliberative indispensability is not an independent guide to what there is. (shrink)

Evolutionary debunking arguments purport to undercut the justification of our moral judgments by showing why a tendency to make moral judgments would evolve regardless of the truth of those judgments. Machery and Mallon (2010. Evolution of morality. In J.M. Doris and The Moral Psychology Research Group (Eds.), The Moral Psychology Handbook (pp. 3-46). Oxford: Oxford University Press) have recently tried to disarm these arguments by showing that moral cognition – in the sense that is relevant to debunking – is not (...) the product of natural selection. Specifically, they present a barrage of increasingly influential challenges against reciprocity-based approaches to moral nativism. In the present paper I defend the nativist account of moral cognition against these criticisms, thereby bolstering the skeptical conclusions of evolutionary debunking arguments. However, Machery and Mallon's critique does successfully highlight several vulnerabilities in Richard Joyce's approach to debunking, suggesting several ways in which it can be revised toward generating a more robust version of the argument.

Internalists and externalists disagree over how intimately normative judgment and motivation are linked. Proponents on both sides typically try to settle the issue by descriptively interpreting our concept of a normative judgment. Unfortunately, this approach has resulted in deep and apparently intractable disagreement. It is time to consider alternative strategies. In this paper, I argue that the internalist/externalist debate is particularly ripe for revisionary arguments that evaluate conceptions of normative judgment in light of the costs and benefits of their adoption. (...) I then develop a revisionary case for externalism by identifying three practical hazards that come with internalist conceptions of normative judgment. Along the way, I show how these internalist hazards are mirrored by externalist benefits. I also argue that two potential benefits of internalism are not very beneficial. Together, these considerations give us strong practical reasons to adopt externalist conceptions of normative judgment, regardless of which account is descriptively accurate. (shrink)

Cornell realists maintain that irreducible moral properties have earned a place in our ontology in virtue of the indispensable role they play in a variety of explanations. These explanations can be divided into two groups: those that employ thin ethical concepts and those that employ thick ethical concepts. Recent work on thick concepts suggests that they are not inherently evaluative in their meaning. If correct, this creates problems for the moral explanations of Cornell realists, since the most persuasive moral explanations (...) are those that employ thick concepts. If thick concepts are not inherently evaluative, then the most plausible explanations on offer cannot support Cornell realism. Moral explanations employing thin concepts, however, are too flimsy to support the view. Unless proponents can develop a compelling story about thick concepts or thin explanations, Cornell realism is in trouble. (shrink)

A central source of support for expressivist accounts of normative discourse is the intimate relationship between normative judgment and motivation. Expressivists argue that normative judgments must be noncognitive, desire-like states in order to be so tightly linked with motivation. Normative statements are then construed as expressions of these noncognitive states. In this paper, I draw on dual-process models in cognitive psychology to respond to this argument. According to my proposal, normative judgments are ordinary beliefs that are typically produced by two (...) kinds of process: intuitive-affective processes and domain-general reasoning. When produced by the first kind of process, motivation and judgment tend to align. When produced by the second kind, motivation and judgment might not align. Since the first kind of process is the most common pathway of normative belief formation, normative judgments are typically accompanied by aligning motivation. This proposal enables cognitivists to explain the intimate link between normative judgment and motivation, thereby removing the major obstacle to interpreting normative statements truth-conditionally.

In The Moral Problem, Michael Smith argues that only motivational internalists can offer an adequate explanation of why changes in moral judgment tend to be accompanied by changes in motivation in morally virtuous people. Smith argues that the failure of motivational externalism to account for this phenomenon amounts to a reductio of the view. In this paper, I draw on dual-process models of moral judgment to develop an externalist response to Smith’s argument. The key to my proposal is that motivationally (...) efficacious states are often the source of our moral judgments, and changes in judgment are typically the result of changes in these states. However, moral judgments can also be formed via an alternative pathway that does not necessarily affect motivation, and so motivation and judgment can come apart. This response not only defuses Smith’s objections to externalism, but challenges Smith to square his internalist proposal with the empirical details of moral judgment. (shrink)

Many environmentalists hold that the loss of a species is intrinsically bad, and many also think that we have moral obligations to species as such. In an attempt to capture these thoughts, some philosophers have suggested that species are bearers of intrinsic value. This approach works well in paradigmatic cases. However, it begins to break down in more difficult scenarios, such as when species boundaries are unclear or when resources are scarce. The case study of the Galápagos giant tortoises in (...) this essay illustrates the limitations of traditional accounts of the non-instrumental value of species. Careful attention to this case indicates how species-centric accounts diverge from the evaluative attitudes of environmentalists, and suggests new directions for theoretical replacements. (shrink)

Abstract:Should we use modern bioengineering techniques to design species? An instrumentalist account of species’ value offers permissive guidance. But what if species exemplify final value? Is it always very good to create new species? Is it always very wrong to blend or modify existing species? In this paper, I argue that both extremes are implausible. However, final value theories struggle to deliver a flexible, moderate treatment of these issues, and so the ethics of designing species presents a challenge for final (...) value theorists. Fortunately, a design-based account of the value of species has the resources to offer plausible, nuanced, context-sensitive guidance on the ethics of designing species. It holds that designing species is sometimes very bad, sometimes quite good, and sometimes neither very good nor very bad. The plausibility of these results lends credibility to the design-based framework, and gives final value theorists reason to prefer the design-based approach. (shrink)

Deferred internalists accept that sometimes, agents can form genuine normative judgments without any accompanying motivation. However, they propose that these judgments can only exist when they are embedded within psychologies or communities in which judgment and motivation typically align. In this paper, I sketch a version of externalism that challenges the interpretation of key evidence claimed by deferred internalists. According to this account, there is a robust but contingent connection between judgment and motivation that is explained by the structure of (...) the neurocognitive apparatus we happen to employ in evaluative thought. This proposal allows that all of our judgments lacking accompanying motivation are contingently parasitic on judgments that are accompanied by motivation. It also suggests that it is not possible to create communities of _beings like us_ whose judgments and motivation radically come apart. These results undermine current strategies for supporting deferred internalism. Proponents will need to find support elsewhere. (shrink)

There has lately been substantial interest in scrutinizing our evaluative attitudes in light of our evolutionary history. However, these discussions have been hampered by an insufficiently expansive vantage. Our history did not begin ex nihilo a few million years ago with the appearance of hominins, or apes, or primates—those are very recent chapters of a much larger story that spans billions of years. This paper situates the mechanisms underlying normative thought within this broader context. I argue that this historical perspective (...) creates difficulties for metaethical nonnaturalists. The expanded scope enables the story to be anchored in negative claims about value, making room for novel epistemological and metaphysical challenges that are more threatening than extant evolutionary debunking arguments.

Evolutionary fitness threats and rewards are associated with subjectively unpleasant and pleasant sensations, respectively. Initially, these correlations appear explainable via adaptation by natural selection. But here I analyse the major metaphysical perspectives on consciousness – physicalism, dualism, and panpsychism – and conclude that none help to understand the adaptive-seeming correlations via adaptation. I also argue that a recently proposed explanation, the phenomenal powers view, has major problems that mean it cannot explain the adaptive-seeming correlations via adaptation either. So the mystery (...) – call it the evolutionary paradox of consciousness – remains. Some have used this mystery to argue for non-naturalistic (e.g. theistic) explanations. But I propose a naturalistic, non-adaptive explanation of the adaptive-seeming correlations: namely, ‘sensational associative learning’ during development. In this perspective, pairing of particular sensations with unconditioned stimuli – fitness rewards or threats – cause the sensations themselves to come to be interpreted as good or bad, respectively. Sensations, like colours, that are not reliably paired with either fitness rewards or threats remain largely unvalenced. Sensational associative learning also provides explanations for adaptive-seeming structural aspects of sensations, such as the observation that sounds of different pitch are experienced as ordinal in correspondence to their wavelengths while the same is not true of colours of different hue. The sensational associative learning perspective appears compatible with physicalism, panpsychism, and dualism (though not epiphenomenalism). (shrink)

Burt's argument relies on a motte-and-bailey fallacy. Burt aims to argue against the value of genetics for social science; instead she argues against certain interpretations of a specific kind of genetics tool, polygenic scores (PGSs). The limitations, previously identified by behavioural geneticists including ourselves, do not negate the value of PGSs, let alone genetics in general, for social science.

This paper argues that promises are proposals in joint practical deliberation, the activity of deciding together what to do. More precisely: to promise to ϕ is to propose (in a particular way) to decide together with your addressee(s) that you will ϕ. I defend this deliberative theory by showing that the activity of joint practical deliberation naturally gives rise to a speech act with exactly the same properties as promises. A certain kind of proposal to make a joint decision regarding (...) one's own actions turns out to have the very same normative effects, under the very same conditions, as a promise. I submit that this cannot be a coincidence: we should conclude that promises and the relevant kind of proposals in joint practical deliberation are one and the same. (shrink)

Evidence-based medicine (EBM) makes use of explicit procedures for grading evidence for causal claims. Normally, these procedures categorise evidence of correlation produced by statistical trials as better evidence for a causal claim than evidence of mechanisms produced by other methods. We argue, in contrast, that evidence of mechanisms needs to be viewed as complementary to, rather than inferior to, evidence of correlation. In this paper we first set out the case for treating evidence of mechanisms alongside evidence of correlation in (...) explicit protocols for evaluating evidence. Next we provide case studies which exemplify the ways in which evidence of mechanisms complements evidence of correlation in practice. Finally, we put forward some general considerations as to how the two sorts of evidence can be more closely integrated by EBM. (shrink)

This paper attempts to nudge the reader in the direction of an enlightened account of democratic choice, a sense of reflective choice which undermines our present support of discriminatory sectarian doctrine. I use Gutmann’s and Altman’s views as prologues to my own, though they might well reject my conclusions about discriminatory religion. I contrast my view with Macedo’s, Gray’s, Larmore’s, Rosenblum’s, and Galston’s.My argument utilizes common sense and relatively uncontroversial metaphysical principles to make it more difficult to dismiss as being (...) on an ontic par with the discriminatory doctrines which it challenges. I argue that discriminatory religion might be allowed to continue to be practiced and expressed by those who would pay their own way, much as with hate groups generally, but I view our continued public subsidization of it as a failure to recognize it for what it is.

Recent work in moral philosophy has emphasized the foundational role played by interpersonal accountability in the analysis of moral concepts such as moral right and wrong, moral obligation and duty, blameworthiness, and moral responsibility (Darwall 2006; 2013a; 2013b). Extending this framework to the field of moral psychology, we hypothesize that our moral attitudes, emotions, and motives are also best understood as based in accountability. Drawing on a large body of empirical evidence, we argue that the implicit aim of the central (...) moral motives and emotions is to hold people - whether oneself or others - accountable for compliance with the demands of morality. Moral condemnation is based in a motive to get perpetrators to hold themselves accountable for their wrongdoing, not, as is commonly supposed, a mere retributive motive to make perpetrators suffer (�2). And moral conscience is based in a genuine motive to hold oneself accountable for behaving in accordance with moral demands, not, as is commonly supposed, a mere egoistic motive to appear moral to others (�3). The accountability-based theory of the moral motives and emotions we offer provides better explanations of the extant empirical data than any of the major alternative theories of moral motivation. Moreover, conceiving of moral psychology in this way gives us a new and illuminating perspective on what makes morality distinctive: its essential connection to our practice of holding one another accountable (�4).

In this paper, we contend that the psychology of addiction is similar to the psychology of ordinary, non-addictive temptation in important respects, and explore the ways in which these parallels can illuminate both addiction and ordinary action. The incentive salience account of addiction proposed by Robinson and Berridge (1993; 2001; 2008) entails that addictive desires are not in their nature different from many of the desires had by non-addicts; what is different is rather the way that addictive desires are acquired, (...) which in turn affects their strength. We examine these “incentive salience” desires, both in addicts and non-addicts, contrasting them with more cognitive desires. On this account, the self-control challenge faced by addicted agents is not different in kind from that faced by non-addicted agents – though the two may, of course, differ greatly in degree of difficulty. We explore a general model of self-control for both the addict and the non-addict, stressing that self-control may be employed at three different stages, and examining the ways in which it might be strengthened. This helps elucidate a general model of intentional action. (shrink)

What accounts for the capacity of ordinary speakers to comprehend utterances of their language? The phenomenology of hearing speech in one’s own language makes it tempting to many epistemologists to look to perception for an answer to this question. That is, just as a visual experience as of a red square is often taken to give the perceiver immediate justification for believing that there is a red square in front of her, perhaps an auditory experience as of the speaker asserting (...) that p gives the competent hearer immediate justification for believing that the speaker has asserted that p. My aim here is to offer reasons for resisting this temptation. I argue that the perceptual model cannot adequately account for the hearer’s justification in many cases. The arguments here also allow us to draw certain further morals about the role of phenomenology in the epistemology of perception. (shrink)

In the context of transgender health, most people are not comfortable with allowing a twelve‐year‐old child with gender dysphoria to elect to undergo gender reassignment surgery. The likelihood is too high that the child would be unable to fully comprehend the scope of a decision that carries significant, permanent consequences, particularly because the decision to surgically change gender is based upon a conception of gender that can fluctuate during adolescent years. Conversely, however, most people would not contend that this fluidity (...) is reason to wholly deny certain medical care such as hormonal treatments to transgender youth, a demographic with extremely high rates of violent behavior, self‐harm, and suicide. This paper will explore ethical considerations to this emerging debate of what therapeutic options should be offered to transgender children and adolescents.Pediatric endocrinologists have been treating gender dysphoric adolescents with puberty‐suppressing drugs and, to a lesser extent, with cross‐sex hormone therapies for more than twenty years. Clinicians and thought leaders have mentioned ethical components of this emerging practice in the few cohort studies and clinical review articles about the subject. However, ethics have generally been a secondary consideration in the medical academic literature. In this paper, I will provide a brief overview of the practice, summarize the current research on hormone treatment for transgender minors, and provide an ethical analysis of the practice. (shrink)

According to current hierarchies of evidence for EBM, evidence of correlation is always more important than evidence of mechanisms when evaluating and establishing causal claims. We argue that evidence of mechanisms needs to be treated alongside evidence of correlation. This is for three reasons. First, correlation is always a fallible indicator of causation, subject in particular to the problem of confounding; evidence of mechanisms can in some cases be more important than evidence of correlation when assessing a causal claim. Second, (...) evidence of mechanisms is often required in order to obtain evidence of correlation. Third, evidence of mechanisms is often required in order to generalise and apply causal claims. While the EBM movement has been enormously successful in making explicit and critically examining one aspect of our evidential practice, i.e., evidence of correlation, we wish to extend this line of work to make explicit and critically examine a second aspect of our evidential practices: evidence of mechanisms.

Mechanistic philosophy of science views a large part of scientific activity as engaged in modelling mechanisms. While science textbooks tend to offer qualitative models of mechanisms, there is increasing demand for models from which one can draw quantitative predictions and explanations. Casini et al. (Theoria 26(1):5–33, 2011) put forward the Recursive Bayesian Networks (RBN) formalism as well suited to this end. The RBN formalism is an extension of the standard Bayesian net formalism, an extension that allows for modelling the hierarchical (...) nature of mechanisms. Like the standard Bayesian net formalism, it models causal relationships using directed acyclic graphs. Given this appeal to acyclicity, causal cycles pose a prima facie problem for the RBN approach. This paper argues that the problem is a significant one given the ubiquity of causal cycles in mechanisms, but that the problem can be solved by combining two sorts of solution strategy in a judicious way.

One way to challenge the substantiveness of a particular philosophical issue is to argue that those who debate the issue are engaged in a merely verbal dispute. For example, it has been maintained that the apparent disagreement over the mind/brain identity thesis is a merely verbal dispute, and thus that there is no substantive question of whether or not mental properties are identical to neurological properties. The goal of this paper is to help clarify the relationship between mere verbalness and (...) substantiveness. I first argue that we should see mere verbalness as a certain kind of discourse defect that arises when the parties differ as to what each takes to be the immediate question under discussion. I then argue that mere verbalness, so understood, does not imply that the question either party is attempting to address is a non-substantive one. Even if it turns out that the parties to the mind/brain dispute are addressing subtly different questions, these might both be substantive questions to which their respective metaphysical views provide substantive answers. One reason it is tempting to reach deflationary conclusions from the charge of mere verbalness is that we fail to distinguish it from the claim that a sentence under dispute is, in a certain sense, indisputable. Another reason is that we fail to distinguish mere verbalness from a certain sort of indeterminacy. While indisputability and indeterminacy plausibly capture forms of nonsubstantiveness, I argue that mere verbalness is insufficient to establish either indisputability or indeterminacy. (shrink)

Category theory reveals commonalities between structures of all sorts. This book shows its potential in science, engineering, and beyond.

Karl Popper (1902-1994) was one of the most influential philosophers of science of the 20th century. He made significant contributions to debates concerning general scientific methodology and theory choice, the demarcation of science from non-science, the nature of probability and quantum mechanics, and the methodology of the social sciences. His work is notable for its wide influence both within the philosophy of science, within science itself, and within a broader social context. Popper’s early work attempts to solve the problem of (...) demarcation and offer a clear criterion that distinguishes scientific theories from metaphysical or mythological claims. Popper’s falsificationist methodology holds that scientific theories are characterized by entailing predictions that future observations might reveal to be false. When theories are falsified by such observations, scientists can respond by revising the theory, or by rejecting the theory in favor of a rival or by maintaining the theory as is and changing an auxiliary hypothesis. In either case, however, this process must aim at the production of new, falsifiable predictions. While Popper recognizes that scientists can and do hold onto theories in the face of failed predictions when there are no predictively superior rivals to turn to. He holds that scientific practice is characterized by its continual effort to test theories against experience and make revisions based on the outcomes of these tests. By contrast, theories that are permanently immunized from falsification by the introduction of untestable ad hoc hypotheses can no longer be classified as scientific. Among other things, Popper argues that his falsificationist proposal allows for a solution of the problem of induction, since inductive reasoning plays no role in his account of theory choice. Along with his general proposals regarding falsification and scientific methodology, Popper is notable for his work on probability and quantum mechanics and on the methodology of the social sciences. Popper defends a propensity theory of probability, according to which probabilities are interpreted as objective, mind-independent properties of experimental setups. Popper then uses this theory to provide a realist interpretation of quantum mechanics, though its applicability goes beyond this specific case. With respect to the social sciences, Popper argued against the historicist attempt to formulate universal laws covering the whole of human history and instead argued in favor of methodological individualism and situational logic.

English mass noun phrases & count noun phrases differ only minimally grammatically. The basis for the difference is ascribed to a difference in the features +/-CT. These features serve the morphosyntactic function of determining the available options for the assigment of grammatical number, itself determined by the features +/-PL: +CT places no restriction on the available options, while -CT, in the unmarked case, restricts the available options to -PL. They also serve the semantic function of determining the sort of denotation (...) associated with demonstrative & quantified noun phrases. The feature -CT requires that the associated denotation be the set whose sole member is the greatest aggregate of which the noun phrase or noun is true; the feature +CT requires that the associated denotation be the set whose members are all & only those minimal aggregates of which the noun phrase or noun is true. At the same time, neither mass NPs nor count NPs that are arguments of a predicate have their predicate evaluated with respect to their denotations. Rather, the predicate is evaluated with respect to an aggregation, a set of aggregates constructed from the denotation of the noun phrase that is an argument of the predicate. 3 Tables, 4 Figures, 74 References.

Pairs of sentences like the following pose a problem for ontology: (1) Jupiter has four moons. (2) The number of moons of Jupiter is four. (2) is intuitively a trivial paraphrase of (1). And yet while (1) seems ontologically innocent, (2) appears to imply the existence of numbers. Thomas Hofweber proposes that we can resolve the puzzle by recognizing that sentence (2) is syntactically derived from, and has the same meaning as, sentence (1). Despite appearances, the expressions ‘the number of (...) moons of Jupiter’ and ‘four’ do not function semantically as singular terms in (2). Hofweber’s primary evidence for this proposal concerns differences in the focus-related communicative functions of (1) and (2). In this paper I raise several serious problems for Hofweber’s proposal, and for his attempt to support it by appeal to focus-related phenomena. I conclude by offering independent evidence for an alternative, purely pragmatic resolution of the ontological puzzle. (shrink)

Intuitively, (1)-(3) seem to express genuine claims (true or false) about what the world is like, attempts to correctly describe parts of extra-linguistic reality. By contrast, it is tempting to regard (4)-(6) as merely reflecting decisions (or conventions, or dispositions, or rules) concerning the terms in which that extra-linguistic reality is described, decisions about which things to label with 'vixen', 'bachelor' or 'cup'.

Several times, when faced with a difficult passage of scripture in Sermones ad populum, Augustine implores his audience, “knock and it shall be opened” (Matt. 7:7c; par. Luke 11:9c). Augustine uses this phrase to stress humility and the human need for God’s activity when interpreting scripture. Studying the archeological record of domestic architecture of locked doors in Roman North Africa elucidates Augustine’s message. Knowledge of the material culture shows that Augustine calls upon Christians to “knock” upon scripture as if it (...) were a door, locked and barred in such a way that it could only be opened from inside. Thus, a reader of scripture is like a petitioner calling from outside a locked door, needing God to open its meaning. Augustine’s use of “knocking” contrasts with the metaphor of “keys” to scripture, which was favored by Tyconius and other early Christian writers. In De doctrina Christiana, Augustine expresses concern that “keys” could lead a person into overconfidence, expecting to unlock obscure passages of the Bible by his or her own power. Augustine’s frequent use of Matt. 7:7c is a call for exegetes to approach scripture with humility. All members of the totus Christus, great and small, must humbly knock. The image of “knocking” provides a versatile theological message: human effort is important, but the meaning of the Bible is ultimately unlocked by God’s activity. (shrink)

In this thesis, I give a metascientific account of causality in medicine. I begin with two historical cases of causal discovery. These are the discovery of the causation of Burkitt’s lymphoma by the Epstein-Barr virus, and of the various viral causes suggested for cervical cancer. These historical cases then support a philosophical discussion of causality in medicine. This begins with an introduction to the Russo- Williamson thesis (RWT), and discussion of a range of counter-arguments against it. Despite these, I argue (...) that the RWT is historically workable, given a small number of modifications. I then expand Russo and Williamson’s account. I first develop their suggestion that causal relationships in medicine require some kind of evidence of mechanism. I begin with a number of accounts of mechanisms and produce a range of consensus features of them. I then develop this consensus position by reference to the two historical case studies with an eye to their operational competence. In particular, I suggest that it is mechanistic models and their representations which we are concerned with in medicine, rather than the mechanism as it exists in the world. -/- I then employ these mechanistic models to give an account of the sorts of evidence used in formulating and evaluating causal claims. Again, I use the two human viral oncogenesis cases to give this account. I characterise and distinguish evidence of mechanism from evidence of difference-making, and relate this to mechanistic models. I then suggest the relationship between types of evidence presents us with a means of tackling the reference-class problem. This sets the scene for the final chapter. Here, I suggest the manner in which these two different classes of evidence become integrated is also reflected in the way that developing research programmes change as their associated causal claims develop.

The literature contains a disconnect between accounts of how humans learn lexical semantic representations for words. Theories generally propose that lexical semantics are learned either through perceptual experience or through exposure to regularities in language. We propose here a model to integrate these two information sources. Specifically, the model uses the global structure of memory to exploit the redundancy between language and perception in order to generate inferred perceptual representations for words with which the model has no perceptual experience. We (...) test the model on a variety of different datasets from grounded cognition experiments and demonstrate that this diverse set of results can be explained as perceptual simulation (cf. Barsalou, Simmons, Barbey, & Wilson, 2003) within a global memory model. (shrink)

For years a debate has raged within the various literatures of philosophy, psychiatry, and psychology over whether, and to what degree, the concepts that characterize psychopathology are social constructions that reflect cultural values. While the majority position among philosophers has been normativist, i.e., that the conception of a mental disorder is value-laden, a vocal and cogent minority have argued that psychopathology results from malfunctions that can be described by terminology that is objective and scientific. Scientists and clinicians have tended to (...) endorse the objectivist position, with some notable exceptions. (shrink)

James K.A. Smith argues that the ontology of participation associated with Radical Orthodoxy is incompatible with a Christian affirmation of the intrinsic being and goodness of creatures. In response, he proposes a Leibnizian view in which things are endowed with the innate dynamism of ‘force’. Creatures have a certain depth of being, and are intrinsically good, just because they each have an inner virtuality that they bring into expression. Such force is said to be a metaphysical component of the agent. (...) In this paper it is asked whether John Milbank's ontology of participation can be defended by distinguishing between two senses of being a subject. Perhaps it is possible for a creature to bring into expression what is an infused ‘alien’ gift rather than a metaphysical component – to be expressive subject, but not ontic subject, for divine power. However, while this distinction promises to make sense of the reception of an indwelling ‘other’ in grace, knowledge and love, neither proper substance nor proper existence can be received in this way. A creature must be the ontic subject for its being, after all. Still, divine being might proceed from God as radical indwelling gift, as non-ontic ground for ontic being. (shrink)
