The so-called ‘Adams’ Thesis’ is often understood as the claim that the assertibility of an indicative conditional equals the corresponding conditional probability—schematically: $${({\rm AT})}\qquad\qquad\quad As(A\rightarrow B)=P({B|A}),{\rm provided}\quad P(A)\neq 0.$$ The Thesis is taken by many to be a touchstone of any theorizing about indicative conditionals. Yet it is unclear exactly what the Thesis is . I suggest some precise statements of it. I then rebut a number of arguments that have been given in its favor. Finally, I (...) offer a new argument against it. I appeal to an old triviality result of mine against ‘Stalnaker’s Thesis’ that the probability of a conditional equals the corresponding conditional probability. I showed that for all finite-ranged probability functions, there are strictly more distinct values of conditional probabilities than there are distinct values of probabilities of conditionals, so they cannot all be paired up as Stalnaker’s Thesis promises. Conditional probabilities are too fine-grained to coincide with probabilities of conditionals across the board. If the assertibilities of conditionals are to coincide with conditional probabilities across the board, then assertibilities must be finer-grained than probabilities. I contend that this is implausible—it is surely the other way round. I generalize this argument to other interpretations of ‘ As ’, including ‘acceptability’ and ‘assentability’. I find it hard to see how any such figure of merit for conditionals can systematically align with the corresponding conditional probabilities. (shrink)

Adams famously suggested that the acceptability of any indicative conditional whose antecedent and consequent are both factive sentences amounts to the subjective conditional probability of the consequent given the antecedent. The received view has it that this thesis offers an adequate partial explication of Ramsey’s test, which characterizes graded acceptability for conditionals in terms of hypothetical updates on the antecedent. Some results in van Fraassen may raise hope that this explicatory approach to Ramsey’s test is extendible to left-nested conditionals, (...) that is, conditionals whose antecedent is itself conditional in form. We argue that this interpretation of van Fraassen’s results is to be rejected. Specifically, we provide an argument from material inadequacy against a generalization of Adams’ thesis for left-nested conditionals. (shrink)

Adams' Thesis states that the probability of a conditional is the probability of the consequent conditional on the antecedent. S. Kaufmann introduced a rival method, the so-called ``local interpretation'', for calculating the probability of a conditional that, according to a purported majority, squares better with intuition in some circumstances. He also gives an example purporting to show that this new method sometimes corresponds to rational action. We challenge the intuitions and expose a mathematical error in the example. We also (...) offer a model for the local interpretivist semantics. This model puts theoretical local interpretivists on ground as solid as that of Thesis abiders for whom conditionals have truth conditions. (shrink)

Church's Thesis (CT) was first published by Alonzo Church in 1935. CT is a proposition that identifies two notions: an intuitive notion of an effectively computable function defined in natural numbers with the notion of a recursive function. Despite the many efforts of prominent scientists, Church's Thesis has never been disproven. There exists a vast literature concerning the thesis. The aim of this book is to provide a one volume summary of the state of research on Church's (...) Thesis. These include the following: different formulations of CT, CT and intuitionism, CT and intensional mathematics, CT and physics, the epistemic status of CT, CT and philosophy of mind, provability of CT and CT and functional programming.

Recent progress in artificial intelligence (AI) has drawn attention to the technology’s transformative potential, including what some see as its prospects for causing large-scale harm. We review two influential arguments purporting to show how AI could pose catastrophic risks. The first argument — the Problem of Power-Seeking — claims that, under certain assumptions, advanced AI systems are likely to engage in dangerous power-seeking behavior in pursuit of their goals. We review reasons for thinking that AI systems might seek power, that (...) they might obtain it, that this could lead to catastrophe, and that we might build and deploy such systems anyway. The second argument claims that the development of human-level AI will unlock rapid further progress, culminating in AI systems far more capable than any human — this is the Singularity Hypothesis. Power-seeking behavior on the part of such systems might be particularly dangerous. We discuss a variety of objections to both arguments and conclude by assessing the state of the debate. (shrink)

H. H. Price (1932) held that experience is essentially presentational. According to Price, when one has an experience of a tomato, nothing can be more certain than that there is something of which one is aware. Price claimed that the same applies to hallucination. In general, whenever one has a visual experience, there is something of which one is aware, according to Price. Call this thesis Item-Awareness.

It is all but universally accepted in epistemology that knowledge is factive: S knows that p only if p. The purpose of this thesis is to present an argument against the factivity of knowledge and in doing so develop a non-factive approach to the analysis of knowledge. The argument against factivity presented here rests largely on empirical evidence, especially extant research into visuomotor noise, which suggests that the beliefs that guide everyday motor action are not strictly true. However, as (...) we still want to attribute knowledge on the basis of successful motor action, I argue that the best option is to replace factivity with a weaker constraint on knowledge, one on which certain false beliefs might still be known. In defence of this point, I develop the non-factive analysis of knowledge, which demonstrates that a non-factive constraint might do the same theoretical work as factivity. (shrink)

Using the Hilbert-Bernays account as a spring-board, we first define four ways in which two objects can be discerned from one another, using the non-logical vocabulary of the language concerned. Because of our use of the Hilbert-Bernays account, these definitions are in terms of the syntax of the language. But we also relate our definitions to the idea of permutations on the domain of quantification, and their being symmetries. These relations turn out to be subtle---some natural conjectures about them are (...) false. We will see in particular that the idea of symmetry meshes with a species of indiscernibility that we will call `absolute indiscernibility'. We then report all the logical implications between our four kinds of discernibility. We use these four kinds as a resource for stating four metaphysical theses about identity. Three of these theses articulate two traditional philosophical themes: viz. the principle of the identity of indiscernibles, and haecceitism. The fourth is recent. Its most notable feature is that it makes diversity weaker than what we will call individuality : two objects can be distinct but not individuals. For this reason, it has been advocated both for quantum particles and for spacetime points. Finally, we locate this fourth metaphysical thesis in a broader position, which we call structuralism. We conclude with a discussion of the semantics suitable for a structuralist, with particular reference to physical theories as well as elementary model theory. (shrink)

I have argued elsewhere that there are facts, and possibilities, that are not purely qualitative. In a second paper, however, I have argued that all possibilities are purely qualitative except insofar as they involve individuals that actually exist. In particular, I have argued that there are no thisnesses of nonactual individuals (where the thisness of x is the property of being x, or of being identical with x), and that there are no singular propositions about nonactual individuals (where a singular (...) proposition about an individual x is a proposition that involves or refers to x directly, perhaps by having x or the thisness of x as a constituent, and not merely by way of x's qualitative properties or relations to other individuals). I am also inclined to believe that there are not yet any thisnesses of individuals that will exist but do not yet, nor any singular propositions about future individuals--and, hence, that all possibilities are purely qualitative except insofar as they involve individuals that already do exist or have existed (counting timeless individuals, if any, as already existing). This thesis about the relation of time to thisness is the subject of the present paper, in which the conclusions of my previous papers will be presupposed. (shrink)

In the past few years, the subject of AI rights—the thesis that AIs, robots, and other artefacts (hereafter, simply ‘AIs’) ought to be included in the sphere of moral concern—has started to receive serious attention from scholars. In this paper, I argue that the AI rights research program is beset by an epistemic problem that threatens to impede its progress—namely, a lack of a solution to the ‘Hard Problem’ of consciousness: the problem of explaining why certain brain states give (...) rise to experience. To motivate this claim, I consider three ways in which to ground AI rights—namely: superintelligence, empathy, and a capacity for consciousness. I argue that appeals to superintelligence and empathy are problematic, and that consciousness should be our central focus, as in the case of animal rights. However, I also argue that AI rights is disanalogous from animal rights in an important respect: animal rights can proceed without a solution to the ‘Hard Problem’ of consciousness. Not so with AI rights, I argue. There we cannot make the same kinds of assumptions that we do about animal consciousness, since we still do not understand why brain states give rise to conscious mental states in humans. (shrink)

Physicalism about colour is the thesis that colours are identical with response-independent, physical properties of objects. I endorse the Argument from Structure against Physicalism about colour. The argument states that Physicalism cannot accommodate certain obvious facts about colour structure: for instance, that red is a unitary colour while purple is a binary colour, and that blue resembles purple more than green. I provide a detailed formulation of the argument. According to the most popular response to the argument, the Physicalist (...) can accommodate colour structure by explaining it in terms of colour experience. I argue that this response fails. Along the way, I examine other interesting issues in the philosophy of colour and colour perception, for instance the relational structure of colour experience and the description theory of how colour names refer.

In this paper I will present a puzzle about visual appearance. There are certain necessary constraints on how things can visually appear. The puzzle is about how to explain them. I have no satisfying solution. My main thesis is simply that the puzzle is a puzzle. I will develop the puzzle as it arises for representationalism about experience because it is currently the most popular theory of experience and I think it is along the right lines. However, everyone faces (...) a form of the puzzle, including the naïve realist. In §1 I explain representationalism about experience. In §§2-3 I develop the puzzle and criticize a response due to Ned Block and Jeff Speaks and another response based on a novel form of representationalism (“sensa representationalism”). In §4 I argue that defenders of “perceptual confidence” (Morrison, Munton, my earlier self) face an instance of the puzzle. In §5 I suggest that everyone faces a form of the puzzle. (shrink)

Bodily pain strikes many philosophers as deeply paradoxical. The issue is that pains seem to bear both physical characteristics, such as a location in the body, and mental characteristics, such being mind-dependent. In this paper I clarify and address this alleged paradox of pain. I begin by showing how a further assumption, Objectivism, the thesis that what one feels in one’s body when one is in pain is something mind-independent, is necessary for the generation of the paradox. Consequently, the (...) paradox can be avoided if one rejects this idea. However, doing so raises its own difficulties, for it is not obvious how anything can possess all of the features we typically associate with bodily pain. To address this puzzle and finally put the paradox of pain to rest, I develop the Embodied View, a novel metaphysical account on which pains are constitutively mind-dependent features of parts of a subject’s body.

The resemblance is plain to see between Kripke’s Wittgenstein introducing bizarre rules such as quaddition (in illustrating the sceptical paradox against theories of meaning) and Goodman’s introducing the equally bizarre grue (in generating the new riddle of induction). But the two sorts of bizarre cases also differ in interesting respects. For those familiar with Goodman’s case, this similarity sparks a strong temptation to enlist to the meaning sceptic’s cause key elements of Goodman’s new riddle, which are missing from Kripke’s case. (...) In this essay, I characterize a natural way of doing just this, which targets dispositionalist solutions to the sceptical paradox. I also show that, despite initial appearances, this new objection to dispositionalism (the symmetry problem) is not nearly as worrisome as originally thought. The solution offered on behalf of semantic dispositionalists does require a trade-off, though, from the severe form of indeterminacy advanced by the meaning sceptic to a much milder thesis. (shrink)

Here I explore a new line of evidence for belief–credence dualism, the thesis that beliefs and credences are distinct and equally fundamental types of mental states. Despite considerable recent disagreement over this thesis, little attention has been paid in philosophy to differences in how our mindreading systems represent the beliefs and credences of others. Fascinatingly, the systems we rely on to accurately and efficiently track others’ mental states appear to function like belief–credence dualists: Credence is tracked like an (...) emotional state, composed of both representational and affective content, whereas belief is tracked like a bare representational state with no affective component. I argue on a preliminary basis that, in this particular case, the mechanics of mentalizing likely pick out a genuine affective dimension to credence that is absent for belief, further strengthening the converging case for belief–credence dualism.

The world or an event? Towards an ontology of war: This paper is an attempt to rethink the ontology of war. Its main object is to determine the ontological status of war and the connection between strategies of armed conflict prevention and the way this status is understood. If to overcome metaphysics we need to reconsider its basis then maybe a similar strategy should be applied in order to overcome war. The source of war is understood here not only in (...) temporal terms, but also as its essence — the ontological basis. The first part of the article invokes several conceptions from the twentieth century, according to which, war was to be overcome by variously understood progress. In those conceptions, as well as in the critical approaches from the beginning of the 21st century, war is treated as an event, a state of affairs. In the next part of my paper, based on Margaret Mead’s anthropological diagnosis, I propound a conception of war as an invention, and therefore — technology. The issue of war is further considered in the context of the twentieth-century philosophy of technology. A thesis is put forward according to which understanding the influence of techne of war over episteme should be the essence of thinking of war prevention. In this study, war is treated as a technology that determines perception. For critical reflection upon war, I use twentieth-century philosophical conceptions linking technology with cognitive processes, especially those formulated by Martin Heidegger and Marshall McLuhan.

There is a substantial literature in epistemology concerning whether knowledge can be transmitted. So-called generative cases of testimony seem to show that testimony cannot transmit knowledge. This article defends the thesis that knowledge transmission by testimony is possible. Once one thinks more carefully about the model of transmission we are employing, however, the stage is set for two surprising results. Supposed counter-examples to knowledge transmission feature transmission in the relevant sense, and, more surprisingly, it is possible to transmit understanding, (...) even when we are construing understanding as an internalist good.

The physis and nomos controversy first emerged in ancient Greek thought. This article explores Castoriadis' reactivation of the issues concerned; in particular, his radicalization of Aristotle's conception of physis and nomos. It suggests that nomos appears as multifaceted in his work. However, three key variations may be identified: empirical nomos, normative nomos and generic nomos. Empirical nomos signifies the human creation of laws. It challenges the notion, long held in western philosophy, that Being = being determined. Although all laws are (...) by humans created and thus in one sense autonomous, Castoriadis further distinguishes normatively between those societies which embrace their self-creating and self-transformative capacity and those which obscure it. Normative nomos, then, refers to the autonomous or heteronomous institution of society. The third sense of nomos refers to the creation of form. In this generic sense, it is argued that the debate shifts from the human to the non-human realm; that nomos also manifests itself in the realm of physis. (shrink)

One important debate between scientific realists and constructive empiricists concerns whether we observe things using instruments. This paper offers a new perspective on the debate over instruments by looking to recent discussion in philosophy of mind and cognitive science. Realists often speak of instruments as ‘extensions’ to our senses. I ask whether the realist may strengthen her view by drawing on the extended mind thesis. Proponents of the extended mind thesis claim that cognitive processes can sometimes extend beyond (...) our brains and bodies into the environment. I suggest that the extended mind thesis offers a way to make sense of realists’ talk of instruments as extensions to the senses and that it provides the realist with a new argument against the constructive empiricist view of instruments.

In certain startling neurological and psychiatric conditions, what is ordinarily most intimate and familiar to us—our own body—can feel alien. For instance, in cases of somatoparaphrenia subjects misattribute their body parts to others, while in cases of depersonalization subjects feel estranged from their bodies. These ownership disorders thus appear to consist in a loss of any feeling of bodily ownership, the felt sense we have of our bodies as our own. Against this interpretation of ownership disorders, I defend Sufficiency, the (...) thesis that every experience of bodily awareness suffices for a feeling of bodily ownership. Since Sufficiency conflicts with a face‐value interpretation of these ownership disorders, the burden is on me to explain away the apparent tension. To do so, I identify and correct what I believe to be the fundamental mistake in the extant literature on the feeling of bodily ownership, namely the tendency to treat the notion of a feeling of bodily ownership as a single psychological construct. Instead, I distinguish the feeling of minimal ownership, the first‐personal character of bodily awareness, from the feeling of affective ownership, the distinctive type of felt concern we have for our bodies. I motivate this distinction by raising the disownership puzzle, the fact that subjects suffering from ownership disorders display an ambiguous set of symptoms, arguing the distinction I draw between minimal and affective ownership is just what is required to resolve the puzzle.

Anti-intellectualists about knowledge-how insist that, when an agent S knows how to φ, it is in virtue of some ability, rather than in virtue of any propositional attitudes, S has. Recently, a popular strategy for attacking the anti-intellectualist position proceeds by appealing to cases where an agent is claimed to possess a reliable ability to φ while nonetheless intuitively lacking knowledge-how to φ. John Bengson & Marc Moffett (2009; 2011a; 2011b) and Carlotta Pavese (2015a; 2015b) have embraced precisely this strategy (...) and have thus claimed, for different reasons, that anti-intellectualism is defective on the grounds that possessing the ability to φ is not sufficient for knowing how to φ. We investigate this strategy of argument-by-counterexample to the anti- intellectualist’s sufficiency thesis and show that, at the end of the day, anti-intellectualism remains unscathed. (shrink)

The aim of the article is to answer the four following questions concerning a proof of Church's Thesis (CT). (1) Can CT be treated as a synthetic definition? (2) How should CT not be understood? (3) How can one understand the expression proof by CT? (4) Is any proof of CT possible at all?

The article analyses the role of Church’s Thesis (hereinafter CT) in the context of the development of hypercomputation research. The text begins by presenting various views on the essence of computer science and the limitations of its methods. Then CT and its importance in determining the limits of methods used by computer science is presented. Basing on the above explanations, the work goes on to characterize various proposals of hypercomputation showing their relative power in relation to the arithmetic hierarchy. (...) The general theme of the article is the analysis of mutual relations between the content of CT and the theories of hypercomputation. In the main part of the paper the arguments for abolition of CT caused by the introduction of hypercomputable methods in computer science are presented and critique of these views is presented. The role of the efficiency condition contained in the formulation of CT is stressed. The discussion ends with a summary defending the current status of Church’s thesis within the framework of philosophy and computer science as an important point of reference for determining what the notion of effective calculability really is. The considerations included in this article seem to be quite up-to-date relative to the current state of affairs in computer science.1. (shrink)

Surprising as it may appear, the philosophical writings of political economist Karl Marx (1818–1883), and those of philosopher, educator Maria Montessori(1870–1952), show thematic resemblances that invite further exploration. These resemblances reflect both keen awareness of the historical period they shared, but also important common threads in their philosophical anthropology, ethical and political values, and goals. In this paper, I examine one central thread which both take as fundamental, namely, the centrality of work in achieving the harmonious development of humankind. I (...) critique Marx’s description of the dynamic process leading to his classless society, because he fails to supply the proximate, efficient cause or middle term that effects this goal. My thesis is that Montessori supplies this missing causal link through her scientific demonstration of the work and function of the child and her holistic understanding of the human person in its full historical dimension, and human and cosmic telos.

Alex Worsnip argues in favor of what he describes as a particularly robust version of fallibilism: subjects can sometimes know things that are, for them, possibly false (in the epistemic sense of 'possible'). My aim in this paper is to show that Worsnip’s argument is inconclusive for a surprising reason: the existence of possibly false knowledge turns on how we ought to model entailment or consequence relations among sentences in natural language. Since it is an open question how we ought (...) to think about consequence in natural language, it is an open question whether there is possibly false knowledge. I close with some reflections on the relation between possibly false knowledge and fallibilism. I argue that there is no straightforward way to use linguistic data about natural language epistemic modals to either verify or refute the fallibilist thesis. (shrink)

The thesis that knowledge is a factive mental state plays a central role in knowledge-first epistemology, but accepting this thesis requires also accepting an unusually severe version of externalism about the mind. On this strong attitude externalism, whether S is in the mental state of knowledge can and often will rapidly change in virtue of changes in external states of reality with which S has no causal contact. It is commonly thought that this externalism requirement originates in the (...) factivity of knowledge. However, despite a number of recent defenses of non-factive accounts of knowledge, epistemology has yet to consider whether a non-factive approach might produce a version of the mental state thesis that can avoid strong externalism. Here I do just that, exploring how three different proposals for weakening factivity might be adapted to theories of knowledge as a non-factive mental state. Contrary to what we might expect, however, none of these proposals are compatible with anything close to attitude internalism about knowledge—or even a substantially weaker externalism. All told, the widespread view that wraps up the severe externalism required for knowledge to be a mental state in factivity is mistaken. Knowledge’s external-world connection runs far deeper than the factivity constraint. (shrink)

The aim of this book is the analysis of Kazimierz Ajdukiewicz's meta-epistemological project of the semantic theory of knowledge and its implementations to solve certain traditional epistemological problems and their metaphysical consequences. This project claims that cognitive problems need to be approached from the perspective of language. One of the results of this analysis is the thesis that the philosophical-linguistic legitimisation for the meta-epistemological project is the philosophy of Edmund Husserl from his Logical Investigations. This is the philosophy that (...) makes it possible to speak reasonably of a close relation between thinking and language and provides thereby the legitimisation for this project. (shrink)

I discuss two forms of the thesis that to have a sensation is to token a sentence in a language of thought-what I call, following Georges Rey, the sensational sentences thesis. One form of the thesis is a version of standard functionalism, while the other is a version of the increasingly popular thesis that for a sensation to have qualia is for it to have a certain kind of intentional content-that is, intentionalism. I defend the basic (...) idea behind the sensational sentences thesis, and argue that the intentionalist version is either false or collapses into the standard functionalist thesis. (shrink)

Science is a process, through which theoretical frameworks are developed, new phenomena defined and discovered, and properties of entities tested. The goal of this dissertation is to illustrate how high-energy physics exemplified the process of theory construction from the 1950s to 1970s, and the promising ways in which it can continue to do so today. The lessons learned from the case studies examined here can inform future physics, and may provide methodological clues as to the best way forward today. I (...) examine the discovery of parity nonconservation in weak interactions, the emergence of Yang-Mills theories as the foundation of the standard model, and contemporary precision testing of quantum electrodynamics. In each of these cases, I examine the details of the physicists’ practice to draw conclusions regarding the epistemology behind successful episodes of theory construction. I reconstruct the methodology of each episode in order to find generalizable lessons to apply to contemporary issues at the frontiers of the search for a theory of quantum gravity. In order to understand the many moving parts in each case study, I introduce a new terminology to distinguish the “parts” of a scientific discipline, inspired by the literature on scientific modelling. These terms—theoretical framework, dynamical model, phenomenological model, experiment, and mathematical tools—are meant to aid in investigating other quantitative scientific disciplines beyond high-energy physics. Ultimately, high-energy physics is at its best when various avenues of theoretical ideas are being pursued, spurring the development of new mathematical techniques to use as tools, and new ideas are quickly and vigorously tested experimentally. Proliferation of new ideas in response to theoretical developments is characteristic of the era of construction of the standard model, and is still ongoing in precision testing of quantum electrodynamics today.

Leibniz argues against Descartes’s conception of material substance based on considerations of unity. I examine a key premise of Leibniz’s argument, what I call the Plurality Thesis—the claim that matter (i.e. extension alone) is a plurality of parts. More specifically, I engage an objection to the Plurality Thesis stemming from what I call Material Monism—the claim that the physical world is a single material substance. I argue that Leibniz can productively engage this objection based on his view that (...) matter is discrete. The discreteness of matter provides two aspects of support for the Plurality Thesis. First, it indicates that the parts of matter do not share boundaries and are, therefore, independent in an important sense. Second, it indicates that the parts of matter are determinate and are, therefore, ontologically prior to the wholes they compose. (shrink)

This paper examines the relationship between monadic and bipolar forms of normativity. As the distinction is usually drawn, monadic normativity concerns whether a given action is right or wrong while bipolar normativity concerns who, if anyone, is wronged in any putative instance of wrongdoing. My central thesis is that in the moral realm, we do well to discard the notion of monadic normativity altogether and focus instead on the contours and limits of bipolar normativity. For by placing greater weight (...) on the significance of wronging particular others, as opposed to simply doing something wrong, we get a more compelling picture of the distinctive importance of morality and its relationship to other norms that govern our lives.

Traditional epistemological reflection on our beliefs about the world attempts to proceed without presupposing or ineliminably depending upon any claims about the world. It has been argued that epistemological externalism fails to engage in the right way with the motivations for this project. I argue, however, that epistemological externalism satisfyingly undermines this project. If we accept the thesis that certain conditions other than the truth of one's belief must obtain in the world outside of one's mind in order for (...) one to have knowledge (or justified belief) about the world, then there is no good intellectual motivation for taking up the traditional project. This results stands even if we accept the traditional theses that knowledge requires justified belief and that justified belief requires the ability to provide good reasons for one's belief.

In the absence of an objective contingency, psychological studies have shown that people nevertheless attribute outcomes to their own actions. Thus, by wrongly inferring control in chance situations people appear to hold false beliefs concerning their agency, and are said to succumb to an illusion of control (IoC). In the current article, we challenge traditional conceptualizations of the illusion by examining the thesis that the IoC reflects rational and adaptive decision making. Firstly, we propose that the IoC is a (...) by-product of a rational uncertain judgment (“the likelihood that I have control over a particular outcome”). We adopt a Bayesian perspective to demonstrate that, given their past experience, people should be prone to ascribing skill to chance outcomes in certain situations where objectively control does not exist. Moreover, existing empirical evidence from the IoC literature is shown to support such an account. Secondly, from a decision-theoretic perspective, in many consequential situations, underestimating the chance of controlling a situation carries more costs than overestimating that chance. Thus, situations will arise in which people will incorrectly assign control to events in which outcomes result from chance, but the attribution is based on rational processes. (shrink)

In this thesis, I show that the commitments of a theological tradition are a conceptual resource which allows new and more robust responses to criticisms of virtue ethics. Until now, theological virtue ethics has not provided a distinctive response to these criticisms and has had to rely on arguments made by secular virtue ethicists. These arguments do not always address theological concerns and do not take advantage of the unique assets of theological ethics. This thesis resolves this problem (...) by providing a chapter-by-chapter confrontation of criticisms of virtue ethics and offering a specifically theological response to each one. In so doing, it identifies the key theological commitments that enable these responses and constitute a particular strength of theological virtue ethics. I consider criticisms that attack the internal coherence or completeness of virtue ethics as well as those which associate virtue ethics with other problematic philosophical positions. In the former group, I address the claims that virtue ethics is not a complete moral theory, that it cannot explain right action, and that it relies on a flawed concept of character. In the latter, I deal with the arguments that virtue ethics must subscribe to moral particularism, moral relativism or egoism. The final part of the thesis returns to the previous chapters to draw out the concepts that are central to these responses. Theological work on the virtues has made important contributions to ethics but has so far been vulnerable to criticism. This thesis addresses this gap and highlights the advantages that theological commitments have to offer virtue ethics. (shrink)

Recent influential interpreters have argued that the philosophy of body that prevails in Leibniz's writings from the 1680' s to about 1704 is both more Aristotelian and less idealistic than the ' monadology' of his last years. It is argued here that the Aristotelian terminology of matter and form which is undoubtedly prominent in the work of Leibniz's ' middle years' was understood by him in a sense that is consistent with the monadology. The monadology is foreshadowed, moreover, in important (...) arguments against the Cartesian thesis that extension is the essence of corporeal substance. Leibniz can be seen as a sort of realist in physics, in contrast with occasionalists. But what is important in that contrast is not so much the reality of matter, as the reality of form, which Leibniz interpreted in terms of the active powers of soul-like substances. (shrink)

We seem to experience a world abounding with events that exhibit dynamic temporal structure; birds flying, children laughing, rain dripping from an eave, melodies unfolding, etc. Seeing objects in motion, hearing and communicating with sound, and feeling oneself move are such common everyday experiences that one is unlikely to question whether humans are capable of perceiving temporal properties and relations. Despite appearing pre-theoretically uncontroversial, there are longstanding and contentious debates concerning the structure of such experience, how temporal perception works, and (...) even whether the perception of change, motion, and succession is possible. The overarching goal of my project is to develop a comprehensive model of temporal perception that does justice to the apparent phenomenology, explains how perception functions to represent temporally structured targets, and generates empirically-informed hypotheses for how such perception is neuro-cognitively realized. I also defend my model against the challenges of anti-realist competitors whom deny the possibility of perceiving temporal relations between non-simultaneous events. (shrink)

In The Birth of Ethics, Philip Pettit carefully argues that Erewhonians would develop concepts that closely resemble our normative concepts – including our moral concepts – and that this reveals a great deal about the nature of normativity in general and morality in particular. The purported revelations about morality include: Thesis #1: Moral concepts ascribe natural properties. Thesis #2 “Full-scale” moral realism is true. Thesis #3: There is a sufficiently good answer to the question, “Why be moral?”In (...) this paper, I do not question Pettit's ingenious argument that the Erewhonians' conceptual repertoire would expand in the way described in his narrative. I instead question whether this narrative supports these metaethical theses. I argue that if our moral concepts were expressively equivalent to Erewhonian moral concepts, that would not ground a “full-scale” moral realism, nor would it give us a sufficiently compelling answer to the question “Why be moral?” Furthermore, I argue that our moral concepts are not expressively equivalent to Erewhonian moral concepts, which puts pressure on the argument that our moral concepts ascribe natural properties. Finally, contra Pettit, I argue that moral concepts do not play the same function in our lives as the analogous concepts play in Erewhonians' lives. (shrink)

What is the relationship between mental states and items of material culture, like notebooks, maps or lists? The extended mind thesis offers an influential and controversial answer to this question. According to ExM, items of material culture can form part of the material basis for our mental states. Although ExM offers a radical view of the location of mental states, it fits comfortably with a traditional, representationalist account of the nature of those states. I argue that proponents of ExM (...) would do better to adopt a fictionalist approach to mental states. In so doing, I suggest, they could retain the important insights underlying the extended mind thesis, while avoiding its more problematic consequences. (shrink)

ABSTRACT Drawing inspiration from Fred Dretske, L. S. Carrier, John A. Barker, and Robert Nozick, we develop a tracking analysis of knowing according to which a true belief constitutes knowledge if and only if it is based on reasons that are sensitive to the fact that makes it true, that is, reasons that wouldn’t obtain if the belief weren’t true. We show that our sensitivity analysis handles numerous Gettier-type cases and lottery problems, blocks pathways leading to skepticism, and validates the (...) epistemic closure thesis that correct inferences from known premises yield knowledge of the conclusions. We discuss the plausible views of Ted Warfield and Branden Fitelson regarding cases of knowledge acquired via inference from false premises, and we show how our sensitivity analysis can account for such cases. We present arguments designed to discredit putative counterexamples to sensitivity analyses recently proffered by Tristan Haze, John Williams and Neil Sinhababu, which involve true statements made by untrustworthy informants and strange clocks that sometimes display the correct time while running backwards. Finally, we show that in virtue of employing the paradox-free subjunctive conditionals codified by Relevance Logic theorists instead of the paradox-laden subjunctive conditionals codified by Robert Stalnaker and David Lewis.

Ethical naturalism is an ethical theory that holds that practical norms are a species of natural norms. It was a position held by almost all ancient ethical theorists, but despite a renaissance among some in the past three quarters of a century, it fell by and large into ill repute centuries ago. This dissertation aims to assess contemporary naturalism in light of that history. In chapter two, I note that contemporary ethical naturalism has had little interest in the historical background (...) of their own theorizing, and I try to fill that gap. The remaining chapters contribute to this task. In chapter three, I explore the concepts of nature at work in some of the writings of Aristotle and Cicero, suggesting that Aristotle has a richer conceptual repertory than usually realised, which could be of use to contemporary ethical naturalists, and that Cicero is needlessly neglected by them. In chapter four, I consider two significant historical developments that make the use of nature concepts difficult today. First, I consider the rise of the empirical human sciences. Second, I consider a line of thinking that concerns nature’s relation to history and society, a line that moves from Rousseau through Kant. I consider too the legacy of this line of thought among neo-Kantians. In chapter five, I consider a final challenge for ethical naturalists, that of genealogy and reflection. Certain kinds of genealogies have been put forth to show the irrelevance of concepts of nature to ethics, but I try to vindicate the notion that ethical naturalism not only can but must be vindicated using a kind of genealogical method. In conclusion, I remark on the prospects of an ethical naturalism more explicitly in conversation with the human sciences and with the history of nature concepts in ethical life. (shrink)

In their recent paper, Kurt Gray and Daniel Wegner offer a model of moral cognition, the “Moral Typecasting” thesis, in which they claim that perceptions of moral agency are inversely related to perceptions of moral patiency. Once we see someone as a moral agent, they claim, we cannot see them as a moral patient (and vice versa). In this paper, I want both to challenge the conception of morality on which the typecasting thesis is fundamentally based and to (...) raise some concerns with the data offered in favor of moral typecasting. I first argue that the dyadic definition of morality is far too narrow to fully capture either all of morality or all of moral psychology. Further, even setting aside the problems with the dyadic notion of morality, I argue that the experimental data Gray and Wegner appeal to fail to demonstrate the sort of mutual exclusivity of and causal interaction between moral perceptions that the moral typecasting thesis proposes. Rather, I suggest, the perceptual differences that do show up in the cited studies arguably arise not from a psychological tendency towards moral typecasting, but from confounding features of the characters in the stimuli.

This essay considers Brian Leiter’s arguments for ‘replacement naturalism’ in the domain of adjudication, his thesis being that we should reject as plausible the ‘normative theory of adjudication’ and replace it witha posterioritheory which best explains the causes of judicial decisions. My central claim is that his ‘naturalizing’ argument is incomplete in the following way: it is against a bad kind of philosophical theory and leaves scope for a better, non-naturalistic, account. Both Leiter’s original arguments for the position and (...) his more recent suggestions in response to critics are considered. (shrink)

I argue that Leibniz’s well-known Argument from Unity is equally an argument from plurality. I detail two main claims about plurality that drive the argument, and I provide evidence that they structure Leibniz’s argument from the late 1670s onwards. First, there is what I call Mereological Nihilism (i.e., the claim that a plurality cannot be made into a true unity by any available means). Second, there is what I call the Plurality Thesis (i.e., the claim that matter is a (...) plurality in need of unity in the first place). I suggest that the Plurality Thesis offers a general analysis of materiality that, in some sense, is the most important aspect of Leibniz’s argument. Finally, I connect these claims about plurality to the common 17th & 18th century commitment known as the actual parts doctrine. (shrink)

Many contemporary philosophers, especially the \"post-modern ones,\" claim that analytical philosophy has committed self-destruction by undermining the position of cognitive realism and questioning its main pillars: theory of objective reference of expressions and correspondential theory of truth. One of such philosophers is Rorty, an indefatigable critic of the conception of \"right representations,\" a concept that - according to him - is \"an empty compliment which we pay to helpful beliefs while realising our intentions.\" In order to support his nihilistic position, (...) Rorty many times refers to Quine. In my paper I seek to answer the question whether Rorty\'s and the views of other post-modern philosophers can be supported by Quine\'s philosophical conceptions. Analysing some selected trends of his philosophy, in particular the thesis about indeterminacy of reference (ontological relativity), I seek to prove that - contrary to Rorty\'s claim - Quine did not devalue the idea of objective reference. I also prove that the semantic concept of truth as relativised to the model of language plays in Quine\'s epistemology an equally essential role to the role of the immanent concept of truth as \"disquotational.\" The former is closer to the correspondential conception of truth. The conclusions which Rorty draws from the conception of Quine are rash, and sometimes they are an outcome of biased interpretation. (shrink)

This essay examines the image of the Eucharist in the poetry of the Peruvian writer César Vallejo. I argue that unlike his modernista forebears, Vallejo regularly employs the Eucharist not as an image of the ecstasy of sexual union, but instead as an image of guilt, melancholy, frustration, and loss. In one sense, such images can be read as deliberately blasphemous distortions of the Christian picture of the Eucharist Vallejo imbibed as a child. My central thesis, however, will be (...) that the same images can also be read, perhaps in part against Vallejo's own intentions, not as distortions of the Eucharist but as offering insights into the nature of the sacrament itself. I develop this thesis in two parts. First, I argue that despite the centrality to eucharistic theology of the themes of communion, spiritual intimacy, and “real presence”—themes that made it an almost irresistible poetic symbol of sexual desire—the Eucharist itself is also and fundamentally a sacrament of absence, delay, and failure. Second, I suggest that by drawing, however implicitly, on these latent elements of eucharistic theology, Vallejo's poetry opens up a space to think about certain aspects of the sacrament which the modernistas’ erotic exuberance tended systematically to obscure.

Through a detailed analysis of the various modes of argumentation employed by Aristotle throughout his natural scientific works, I aim to contribute to the growing scholarship on the relation between Aristotle’s theory of science and his actual scientific practice. I challenge the standard reading of Aristotle as a methodological empiricist and show that he permits a variety of non-empirical arguments to support controversial theses in properly scientific contexts. Specifically, I examine his use of logical (logikôs) argumentation in the discussion of (...) mule sterility in Generation of Animals II 8, rational (kata ton logon) argumentation in his discussion of cardiocentrism throughout the biological works, and the method of division in Posterior Analytics II 13.
