Mark Balaguer argues for full blooded platonism (FBP), and argues that FBP alone can solve Benacerraf's familiar epistemic challenge. I note that if FBP really can solve Benacerraf's epistemic challenge, then FBP is not alone in its capacity so to solve; RFBP—really full blooded platonism—can do the trick just as well, where RFBP differs from FBP by allowing entities from inconsistent mathematics. I also argue briefly that there is positive reason for endorsing RFBP.

Mark Balaguer's Platonism and Anti-Platonism in Mathematics presents an intriguing new brand of platonism, which he calls plenitudinous platonism, or more colourfully, full-blooded platonism. In this paper, I argue that Balaguer's attempts to characterise full-blooded platonism fail. They are either too strong, with untoward consequences we all reject, or too weak, not providing a distinctive brand of platonism strong enough to do the work Balaguer requires of it.

In this paper, I discuss full-blooded Platonism as a response to the skeptical problem in the philosophy of mathematics as to how empirical beings can cognize non-empirical mathematical objects. I then attempt to develop an analogous position regarding the applicability of concepts to reality in response to the skeptical problem regarding how we can cognize an objective reality through human-constructed concepts. If all concepts meeting certain minimal conditions structure reality under some aspect, then objective knowledge is possible, (...) regardless of how these concepts arose historically. (shrink)

In ‘Just what is full-blooded platonism?’ Greg Restall outlines several objections to Mark Balaguer's theory of full-blooded platonism. I reply to these objections by explicating the semantic framework for the reference of mathematical terms that full-blooded platonism requires. Expanding upon these replies, I then explain how the full-blooded platonist, in light of the explicated semantic framework, should treat mathematical terms and statements in order to avoid certain pitfalls.

In this book, Balaguer demonstrates that there are no good arguments for or against mathematical platonism. He does this by establishing that both platonism and anti-platonism are defensible views. Introducing a form of platonism ("full-blooded platonism") that solves all problems traditionally associated with the view, he proceeds to defend anti-platonism (in particular, mathematical fictionalism) against various attacks, most notably the Quine-Putnam indispensability attack. He concludes by arguing that it is not simply that (...) we do not currently have any good argument for or against platonism, but that we could never have such an argument and, indeed, that there is no fact of the matter as to whether platonism is correct.

Is consistency the sort of thing that could provide a guide to mathematical ontology? If so, which notion of consistency suits this purpose? Mark Balaguer holds such a view in the context of platonism, the view that mathematical objects are non-causal, non-spatiotemporal, and non-mental. For the purposes of this paper, we will examine several notions of consistency with respect to how they can provide a platon-ist epistemology of mathematics. Only a Gödelian notion, we suggest, can provide a satisfactory guide (...) to a platonist ontology. Is consistency the sort of thing that could provide a guide to mathematical ontology? If so, which notion of consistency suits this purpose? Mark Bala-guer holds such a view in the context of platonism, the view that mathematical objects are non-causal, non-spatiotemporal, and non-mental. Balaguer's version of Platonism, Full-Blooded Platonism (FBP), is the view that "there are as many abstract mathematical objects as there could be-i.e., there actually exist abstract mathematical objects of all possible kinds" (Balaguer, 2017, p. 381). He continues: Since FBP says that there are abstract mathematical objects of all possible kinds, it follows that if FBP is true, then every purely mathematical theory that could be true-i.e., that is internally consistent-accurately describes some collection of actually existing abstract objects. Thus it follows from FBP that in order to acquire knowledge of abstract objects, all we have to do is come up with an internally consistent purely mathematical theory (and know that it is internally consistent).

A response is given here to Benacerraf's 1973 argument that mathematical platonism is incompatible with a naturalistic epistemology. Unlike almost all previous platonist responses to Benacerraf, the response given here is positive rather than negative; that is, rather than trying to find a problem with Benacerraf's argument, I accept his challenge and meet it head on by constructing an epistemology of abstract (i.e., aspatial and atemporal) mathematical objects. Thus, I show that spatio-temporal creatures like ourselves can attain knowledge about (...) mathematical objects by simply explaininghow they can do this. My argument is based upon the adoption of a particular version of platonism — full-blooded platonism — which asserts that any mathematical object which possiblycould exist actuallydoes exist.

This is the third part of the study concerning the problem of ontological reductions in mathematics. In this part, the problem of reconstruction of (parts of) mathematics in theories weaker than full ZFC is discussed. The tools from reverse mathematics are used, and the results are discussed from the point of view of various versions of realism (Gödel’s realism, Quine’s quasi-empiricism and Balaguer’s Full-Blooded Platonism). Some problems concerning the possibility of discussing these problem outside the conceptual (...) system of set theory are also addressed. (shrink)

Set-theoretic pluralism is an increasingly influential position in the philosophy of set theory (Balaguer [1998], Linksy and Zalta [1995], Hamkins [2012]). There is considerable room for debate about how best to formulate set-theoretic pluralism, and even about whether the view is coherent. But there is widespread agreement as to what there is to recommend the view (given that it can be formulated coherently). Unlike set-theoretic universalism, set-theoretic pluralism affords an answer to Benacerraf’s epistemological challenge. The purpose of this paper is (...) to determine what Benacerraf’s challenge could be such that this view is warranted. I argue that it could not be any of the challenges with which it has been traditionally identified by its advocates, like of Benacerraf and Field. Not only are none of the challenges easier for the pluralist to meet. None satisfies a key constraint that has been placed on Benacerraf’s challenge. However, I argue that Benacerraf’s challenge could be the challenge to show that our set-theoretic beliefs are safe – i.e., to show that we could not have easily had false ones. Whether the pluralist is, in fact, better positioned to show that our set-theoretic beliefs are safe turns on a broadly empirical conjecture which is outstanding. If this conjecture proves to be false, then it is unclear what the epistemological argument for set-theoretic pluralism is supposed to be. (shrink)

Problems of logical theory choice are current being widely dis- cussed in the context of anti-exceptionalist views on logic. According to those views, logic is not a special science among others, so, in particular, the methodology for theory choice should be the same in logic as for other scientific disciplines. Richard Routley advanced one such methodology which meshes well with anti-exceptionalism, and argued that it leads one to choosing one single logic, which is a kind of ultralogic. We argue that (...) the choice for only one correct system of logic may be rejected on the basis of the methodology proposed by Routley and, furthermore, that taking anti-exceptionalism about logic seriously recommends that a pluralist view of logic should be accepted. We call this view “full-blooded anti-exceptionalism”, and the resulting view on logic, lacking a proper name, “local pluralism”. (shrink)

I cannot fully respond here to all of the subtle and sophisticated criticisms of my full-blooded Epicureanism that have been advanced by Frederik Kaufman, Stephan Blatti, TM Wilkinson and Walter Glannon.1–4 Accordingly, I will focus on correcting some misunderstandings of my position and on responding to some of the most pressing objections.Kaufman holds that the implications of my full-blooded Epicureanism are ‘startling,’ since if I am right “killing or being killed in war will be morally inconsequential, (...) saving people from death will be without merit, and execution could not count as punishment”.1 Second, he criticises my distinction between something being a harm to a person , and something being a harm for a person . Kaufman holds that this distinction does little work, and that it is question-begging to assert that only harms to a person are harms proper. Finally, Kaufman criticises my view that there might be instances of harmless wrongdoing, claiming that it is ‘a conceptual truth’ that ‘to be wronged entails being harmed’. …. (shrink)

Entitlement is defined as a sort of epistemic justification that one can possess by default – a sort of epistemic justification that does not need to be earned or acquired. Epistemologists who accept the existence of entitlement generally have a certain anti-sceptical role in mind for it – entitlement is intended to help us resist what would otherwise be compelling radical sceptical arguments. But this role leaves various details unspecified and, thus, leaves scope for a number of different potential conceptions (...) of entitlement. At one extreme there are conceptions that portray entitlement as a weak, attenuated epistemic status and, at the other, we have conceptions that portray entitlement as something potent and strong. Certain intermediate conceptions are also possible. In this paper, I shall argue that the weak and intermediate conceptions of entitlement do not survive careful scrutiny, and the stronger conceptions – while they do, in a way, strain credulity – are the only conceptions that are ultimately viable.

Gareth Evans produced a powerfulline of argument against Quine's well-known Thesis of the Inscrutability of Reference. In one part of his attack, Evans argued that, under certain conditions, structural simplicity may become truth-conducive for semantic theories. Being structurally more complex than the standard semantic theory, perverse semantic theories a la Quine are an easy prey for Evans' considerations. The bulk of the paper will be devoted to addressing Evans' criticism. By reviewing the classical/connectionist debate in cognitive science between a hypothetical (...) sympathizer of “cognitive orthodoxy" and the friend ofconnectionism, I shall contend that the Quinean has nothing to fear from a classical reading of Evans' considerations.

In lieu of an abstract, here is a brief excerpt of the content:Wuthering Heights: The Romantic AscentMartha NussbaumI“If I were in heaven, Nelly,” she said, “I should be extremely miserable.”“I dreamt, once, that I was there.... [H]eaven did not seem to be my home; and I broke my heart with weeping to come back to earth; and the angels were so angry that they flung me out, into the middle of the heath on the top of Wuthering Heights, where I (...) woke sobbing for joy.” 1Cathy’s soul cannot live in the Christian heaven. For her soul, she explains, is the same as Heathcliff’s soul, and the heavenly soul of Linton is as different from theirs “as a moonbeam from lightning, or frost from fire” (p. 95). Much later, as she lies on her deathbed, now the wife of Edgar Linton, thinking the Linton thought that what she wants is an escape into “that glorious world” of paradise and peace, Heathcliff watches her with burning eyes. At last she calls to him:In her eagerness she rose and supported herself on the arm of the chair. At that earnest appeal he turned to her, looking absolutely desperate. His eyes, wide and wet, at last flashed fiercely on her; his breast heaved convulsively. An instant they held asunder, and then how they met I hardly saw, but Catherine made a spring, and he caught her, and they were locked in an embrace from which I thought my mistress would never be released alive: in fact, to my eyes, she seemed directly insensible. He flung himself into the nearest seat, and on my approaching hurriedly to ascertain if she had fainted, he gnashed at me, and foamed like a mad dog, and gathered her to him with greedy jealousy. I did not feel as if I were in the company of a creature of my own species: it appeared that he would not understand, though I spoke to him; so I stood off, and held my tongue, in great perplexity.(pp. 188–89) [End Page 362]Brontë’s description alludes to the imagery of the Christian ascent tradition. As in Augustine and Dante, love is a flame that animates the eyes, a lightning bolt that pierces the fog of our obtuse daily condition; as in that tradition, love’s energy causes the lover to leap away from the petty egoism of the daily into an ecstatic and mutually loving embrace. But we know we are far from the world of the Christian ascent, even its erotic Augustinian form. Cathy’s spring is not an upward, but a horizontal movement—not toward heaven, but toward her beloved moors and winds, severed from which she would find heaven miserable; not toward God but toward Heathcliff, the lover of her soul. Nor is there redemption into heaven in this work; there is, if anything, a redemption from a world dominated by the imagination of heaven, into a world that the pious Ellen Dean can recognize only as an animal world, a world inhabited by creatures of a different species, who probably do not understand language, so thoroughly are they identified with the energy of the body. A few hours after Cathy’s death Heathcliff, as Ellen Dean tells us, in a sudden “paroxysm of ungovernable passion,” dashes his head against the knotted trunk of a tree, splashing the bark with blood, “and, lifting up his eyes, howled, not like a man, but like a savage beast being goaded to death with knives and spears” (p. 197). It is in his world alone, it would seem, that flame is truly found. As Cathy said to Edgar Linton, “Your cold blood cannot be worked into a fever: your veins are full of ice-water; but mine are boiling, and the sight of such chillness makes them dance.”Brontë’s novel situates itself within a long tradition of writing about love and its ascent or purification. This tradition, inaugurated by Socrates’ description of the ladder of love in Plato’s Symposium, is continued by later Platonists, and radically reformulated by Christian thinkers, who stress, against Plato, the soul’s receptivity and vulnerability to the inscrutable operations of grace. In both the Platonic and... (shrink)

'Middle' Platonism has some claim to be the single most influential philosophical movement of the last two thousand years, as the common background to 'Neoplatonism' and the early development of Christian theology. This book breaks with the tradition of considering it primarily in terms of its sources, instead putting its contemporary philosophical engagements front and centre to reconstruct its philosophical motivations and activity across the full range of its interests. The volume explores the ideas at the heart of (...) Platonist philosophy in this period and includes a comprehensive selection of primary sources, a significant number of which appear in English translation for the first time, along with dedicated guides to the questions that have been, and might be, asked about the movement. The result is a tool intended to help bring the study of Middle Platonism into mainstream discussions of ancient philosophy. (shrink)

[Presented at the 52nd Annual Conference of the Society for Phenomenology and Existential Philosophy (SPEP), University of Oregon, 24-26 October. Part of the panel Events, Actions and the Problem of Agency in the Wake of Deleuze’s Logic of Sense, organized in collaboration with Sean Bowden and James Williams.] In this paper I will bring the positions of Gilles Deleuze and Paul Ricoeur into proximity with each other in order to draw out points of conflict. I do not aim to solve (...) these conflicts, nor to develop them into a full clash. Rather, I will show that both Ricoeur and Deleuze develop a theory of novelty that can be characterized as a reversal of Platonism. These theories are not opposed per se, but they differ in orientation. Deleuze situates novelty in the virtual event. This virtual event can be understood as a singular point of transition that transforms one system into another. Or to catch the event in a somewhat more concrete image, it is a kind of metamorphosis (in Kafka’s sense). In contrast, Ricoeur situates novelty in human actions that are played out as a fruitful tension between two poles. This tension opens up a field of potentiality in which new ideas and novel meanings can emerge. Ricoeur has analysed this tension on many levels. Its most basic structure can be found in what Ricoeur calls a living metaphor. This living metaphor is itself something ‘in action’; it brings two opposed semantic fields into a fruitful tension with each other. This tension reveals a previously unnoticed proximity between these two semantic fields, without destroying their distance. In this way a new, third semantic field is opened up that is only given in potential. Ricoeur argues that it is within tensions like this that generative differences arise, resulting in new ideas and novel meanings. The main point of divergence between Deleuze and Ricoeur can therefore be framed in two contrasting pairs: virtual event versus human action; point of transition versus tension (or: metamorphosis versus metaphor).

Apuleius of Madauros, writing in the latter half of the second century CE in Roman North Africa, is best known to us today for his Latin fiction, the Metamorphoses aka The Golden Ass, about a man who turned into a donkey and back again. However, he was also a Platonic philosopher, who, even though many of his writings are lost, wrote a range of rhetorical and philosophical works which survive to this day. This book examines these works to reveal how (...) Apuleius' Platonism is a result of his 'impersonation of philosophy', that is, a rhetorically powerful methodological tool that allows him to 'speak' on behalf of Plato and his philosophy. This book is the first exploration of the full scope of his idiosyncratic brand of Platonism across his multifarious literary corpus and is a major contribution to the study of the dynamic between literature and philosophy in antiquity and beyond.

The ABO histo‐blood group, first discovered over a century ago, is found not only in humans but also in many other primate species, with the same genetic variants maintained for at least 20 million years. Polymorphisms in ABO have been associated with susceptibility to a large number of human diseases, from gastric cancers to immune or artery diseases, but the adaptive phenotypes to which the polymorphism contributes remain unclear. We suggest that variation in ABO has been maintained by frequency‐dependent or (...) fluctuating selection pressures, potentially arising from co‐evolution with gut pathogens. We further hypothesize that the histo‐blood group labels A, B, AB, and O do not offer a full description of variants maintained by natural selection, implying that there are unrecognized, functionally important, antigens beyond the ABO group in humans and other primates.

Platonists in mathematics endeavour to prove the truthfulness of the proposal about the existence of mathematical objects. However, there have not been many explicit proofs of this proposal. One of the explicit ones is doubtlessly Baker’s Enhanced Indispensability Argument, formulated as a sort of modal syllogism. We aim at showing that the purpose of its creation – the defence of Platonist viewpoint – was not accomplished. Namely, the second premise of the Argument was imprecisely formulated, which gave space for various (...) interpretations of the EIA. Moreover, it is not easy to perceive which of the more precise formulations of the above-mentioned premise would be acceptable. For all these reasons, it is disputable whether the EIA can be used to defend Platonist outlook. At the beginning of this century, Baker has shown that the so-called Quine-Putnam Indispensability Argument can not provide “full” platonism - a guarantee of the existence of all mathematical objects. It turns out, however, that the EIA has a similar disadvantage. (shrink)

‘Modest’ and ‘full-blooded’ conceptions of meaning disagree on whether we should try to provide explanations of reference. In this paper, I defend a psychological brand of the full-blooded program. As I understand it, there are good reasons to provide a psychological explanation of referential abilities. This explanation is to be framed at an intermediary level of description between the personal level and the explanations provided by neuroscience. My defense of this program has two parts: First, I (...) display the explanatory insufficiency of truth-conditional semantics and, second, I respond to some widespread arguments against psychological explanations of referential abilities.

In Plato’s _Laws_ is the earliest surviving fully developed cosmological argument. His influence on the philosophy of religion is wide ranging and this book examines both that and the influence of religion on Plato. Central to Plato’s thought is the theory of forms, which holds that there exists a realm of forms, perfect ideals of which things in this world are but imperfect copies. In this book, originally published in 1959, Feibleman finds two diverse strands in Plato’s philosophy: an idealism (...) centered upon the Forms denying full ontological status to the realm of becoming, and a moderate realism granting actuality equal reality with Forms. For each strand Plato developed a conception of religion: a supernatural one derived from Orphism, and a naturalistic religion revering the traditional Olympian deities. (shrink)

The liberty of the woman is at stake in a sense unique to the human condition and so unique to the law. The mother who carries a child to full term is subject to anxieties, to physical constraints, to pain that only she must bear.

Her suffering is too intimate and personal for the State to insist, without more, upon its own vision of the woman's role ….For years, Jehovah's Witnesses have posed a challenge to the medical profession.

Objective: To systematically analyze the effects of art therapy on the levels of depression, anxiety, blood glucose, and glycated hemoglobin in diabetic patients.Methods: We searched Cochrane Library, PubMed, Embase, and ClinicalTrials.gov databases from inception to January 24, 2021. The language of publication was limited to English. Randomized controlled trials that used art therapy to improve mental disorders in diabetic patients were involved. After selection of eligible studies, data were extracted, including the first author's full-name, year of publication, the first (...) author's country of residence, number of intervention and control groups, the mean age of participants, method of intervention, duration of follow-up, and outcome measures. Assessment of quality of the included studies and data extraction were independently carried out by two researchers. RevMan 5.3 software was used to perform statistical analysis.Results: A total of 396 samples from five studies were included, and the eligible studies were RCTs with a parallel design. Methods of art therapy included music therapy and painting therapy. The results showed that compared with the control group, art therapy could positively affect the levels of depression [standardized mean difference, −1.36; 95% confidence interval, ; P < 0.00001] and blood glucose in diabetic patients [mean difference, −0.90; 95% CI, ; P < 0.0001], while it had no influence on the levels of anxiety [SMD, −0.31; 95% CI, ; P = 0.32] and glycated hemoglobin [MD, 0.22; 95% CI, ; P = 0.07].Conclusion: Art therapy may have significant effects on the levels of depression and blood glucose for diabetic patients.

Aristotle has famously made the claim that having the right emotion at the right time is an essential part of moral virtue. Why might this be the case? I consider five possible relations between emotion and virtue and argue that an adequate answer to this question involves the epistemic status of emotion, that is, whether the perceptual awareness and hence the understanding of the object of emotion is like or unlike the perceptual awareness of an unemotional awareness of the same (...) object. If an emotional awareness does not have a unique character, then it is unlikely that emotions provide an understanding that is different from unemotional states of awareness: they are perhaps little more than “hot-blooded” instances of the same understanding. If, on the other hand, an emotional state involves a perceptual awareness that is unique to the emotion, then emotions are cognitively significant, providing an understanding of the object of the emotion that is absent in a similar but unemotional episode of awareness. I argue the latter and substantiate the claim that emotions are essential to moral virtue because they can be essential to a full understanding of the situations that they involve. In such cases, emotions are not merely a symptom of the possession of an adequate understanding, but are rather necessary for having an adequate understanding. (shrink)

The demonstration of a loophole-free violation of Bell's inequality by Hensen et al. (2015) leads to the inescapable conclusion that timelessness and abstractness exist alongside space-time.

Full-Blooded religion is not acceptable in mainstream bioethics. This article excavates the cultural history that led to the suppression of religion in bioethics. Bioethicists typically fall into one of the following camps. 1) The irreligious, who advocate for suppressing religion, as do Timothy F. Murphy, Sam Harris, and Richard Dawkins. This irreligious camp assumes American Fundamentalist Protestantism is the real substance of all religions. 2) Religious bioethicists, who defend religion by emphasizing its functions and diminishing its metaphysical commitments. (...) Religious defenders empty religion of its theology to present its feel-good functions in a way that is acceptable to the irreligious. However, religion reduced to its functions dissolves into a counter-culture that may counteract materialism but lacks the power to motivate much more. This article criticizes both camps, as both presume Enlightenment myths and consequently neuter religion. Both irreligious and religious bioethicists commonly presume Enlightenment myths about secularity and religion. Secularity is presumed neutral and rational. Religion is presumed divisive and irrational. This myth provides built-in value-judgements; we have already judged secularity as good and religion as bad. Much of the debate over religion in bioethics is arguing over false stereotypes of religion. Consequently, mainstream bioethics neuters religion, while the irreligious are gifted political power to define the field. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:After Gödel: Platonism and Rationalism in Mathematics and LogicMark C. R. SmithRichard Tieszen. After Gödel: Platonism and Rationalism in Mathematics and Logic. Oxford-New York: Oxford University Press, 2011. Pp. xi + 245. Cloth, $75.00.Tieszen’s new book offers a synthesis and extension of his longstanding project of bringing the method of Husserl’s phenomenology to bear on fundamental questions—both epistemological and ontological—in the philosophy of mathematics. Gödel held (...) Husserl’s philosophy in high regard, and thought that it offered the most promising avenue for an adequate understanding of the foundations of mathematical thought and practice, but Gödel himself did not give a full systematic statement of how phenomenology might carry out that project. Tieszen takes up the task in this book, which is structured around two main guiding themes. The first is to locate the sources of Gödel’s philosophical views—principally [End Page 303] in Plato, Leibniz, and of course Husserl, along with Kant as a sort of backcloth—and the second is to argue that from these materials, a promising rationalism in mathematics and logic can be consistently articulated. Along the way we also encounter a good many of Gödel’s arguments against an array of reductive positions, Hilbert’s formalism and Carnap’s “logical syntax” project among them, as well as arguments against the prospects of a mechanical or purely computational understanding of the human mind. Many of the arguments (both negative and positive) stem from a reflection on the consequences of Gödel’s landmark incompleteness results of 1931.The core of Tieszen’s positive proposals comes in chapters 4, 5, and 6: here is where we meet with “constituted Platonism,” Tieszen’s name for the rationalist, realist synthesis of Husserl’s method and Gödel’s mathematical insights. Methodologically, the starting point is the actual practice of mathematics as a human undertaking, and its conditions of possibility. At the most general level, it is characteristic of thought to be intentional, that is, to be (or try to be) about something, to have a target, to be a bearer of meaning. So it goes for thought about items in sensory awareness, about fictional objects, or about mathematical subject-matter. Concerning the latter, what we encounter in mathematical experience are frequently “phenomena that resist our will, so that we are ‘forced’ in certain directions” (170); what accounts for this resistance to our will are invariants, which have the further characteristics of repeatability—both for a single subject, and among many subjects—and availability for convergence (221), which, I take it, means availability as structures or concepts upon which many independent rational investigators will come to rest. Thinking mathematical thoughts is quite unlike thinking thoughts about fictional items, because fictions are indefinitely plastic in the face of human will. It is also unlike thought about sensory items, in that the intentional objects at issue are not available to outer sense; but from another angle it is more like thought about real material items than imaginary beings, because our mathematical thoughts are exposed to the possibility of error or misrepresentation in various ways. (An elementary example: most people think that 1 is distinct from 0.9999... repeating: this is a misrepresentation, because they are in fact identical.)The phenomenology of mathematical practice is such that we assay various conjectures and proposals about invariants already given to consciousness by previous practice, and discover what further invariant structures or concepts are revealed as necessary constraints upon the various possibilities that we can experimentally float for ourselves. Sometimes our conjectures or intentions are fulfilled, sometimes they are frustrated; but it is the very fact of fulfillment and frustration which points us to a Platonic reality. It is not the noumenal realm of the “naive” Platonist, in Tieszen’s phrase, but nevertheless an objective reality marked off “on the basis of what stabilizes or becomes invariant in our experience, on the basis of what has a history and a sedimentation that permits of further elaboration, development, constraints, surprises, and so on” (101). In something like this way, human reason and consciousness “constitute the meaning of being” of mathematical objects... (shrink)

In this book's companion volumes (Warrant: The Current Debate and Warrant and Proper Function), I examined the nature of epistemic warrant, that quantity, enough of which distinguishes knowledge from mere true belief; in this book, I turn to the question of whether Christian belief can be justified, rational, and warranted. Among objections to Christian belief, we can distinguish between de facto objections and de jure objections, i.e., between those that claim that Christian belief is false (de facto objections) and those (...) that claim that Christian belief, whether or not true, is at any rate unjustifiable, or rationally unjustified, or irrational, or not intellectually respectable, or in some other way rationally unacceptable (de jure objections). The main question of this book is the question of whether there are any viable de jure objections to Christian belief; I argue that there are not. In Part I (Chs. 1 and 2), I consider and address an initial objection to my project: the objection that there isn’t really any such thing as Christian belief (or at any rate that Christian belief is incoherent) since human concepts cannot apply to a transcendent God. In Part II, I explore, first, the question of whether a viable de jure objection to Christian belief can be developed in terms of justification or rationality (Chs. 3 and 4); after arguing for a negative answer to that question, I turn to the objections offered by Freud, Marx, and Nietzche, objections best understood as the claim that theistic and Christian belief lack warrant (Ch. 5). In Part III, Ch. 6, I address this claim, doing so by presenting a model of how it is that belief in God can have warrant, and even warrant sufficient for knowledge; I call this model the Aquinas/Calvin (or A/C) model, since it draws on the thought of Thomas Aquinas and John Calvin. In Ch. 7, I consider the noetic effects of sin, and the way in which the existence of sin throws a monkey wrench into the A/C model. In Chs. 8 and 9, I extend the A/C model in such a way as to deal both with sin and with the full panoply of Christian belief (trinity, incarnation, atonement, resurrection, etc.); the extended A/C model shows how full‐blooded Christian belief (not just theistic belief) can have warrant. After dealing with objections to the A/C model in Ch. 10, I turn in Part IV to potential or actual defeaters for Christian belief – possible reasons to give it up or hold it less firmly. The proposed defeaters I examine relate to projection theories of religious belief (Ch. 11), contemporary historical biblical criticism (Ch. 12), postmodernism and religious pluralism (Ch. 13), and the age‐old problem of evil (Ch. 14); none of these, I argue, presents a serious challenge to the warrant Christian belief can enjoy.

In Death, Posthumous Harm, and Bioethics, I argue that we should endorse a trio of views that together constitute what I term full-blooded epicureanism: That death is not a harm to the person who dies, and that persons can neither be harmed nor wronged by events that occur after their deaths. After defending full-blooded epicureanism, I argue that it can be used to illuminate various contemporary bioethical debates, including those concerning posthumous organ procurement, assisted posthumous reproduction, (...) medical research on the dead, and posthumous medical confidentiality.

ABSTRACT The goal of this paper is to find out if Michael Smith's version of the causal theory of action is able to solve David Velleman's agency par excellence challenge. Smith has claimed that his theory can deal with the challenge insofar as the exercise of the capacity to be instrumentally rational plays the intermediating role which Velleman thinks of the agent as playing in the causation of action. However, I argue Smith misunderstands the challenge at hand, thereby failing to (...) find the agent's proper role in action explanation. Moreover, I claim Velleman's objection puts Smith's account of the causal theory in trouble by showing it cannot reconcile the causal explanation of intentional action with our ordinary conception of agency. If Smith intends to explain what a 'full-blooded' intentional action is, I then believe he needs to incorporate into his theory a more robust account of rational guidance. Resumo: O objetivo deste artigo é descobrir se a versão da teoria causal da ação de Michael Smith é capaz de resolver o desafio da agência por excelência de David Velleman. Smith tem sustentado que sua teoria pode lidar com o desafio na medida em que o exercício da capacidade de ser instrumentalmente racional desempenha o papel que Velleman imagina que o agente desempenhe na causação da ação. Contudo, argumento que Smith não compreende corretamente o desafio em questão, falhando desse modo em encontrar o papel adequado do agente na explicação da ação. Além disso, defendo que a objeção de Velleman põe a abordagem da teoria causal de Smith em apuros ao mostrar que ela não é capaz de reconciliar a explicação causal da ação intencional com nossa concepção ordinária de agência. Se Smith pretende explicar o que uma ação intencional 'plena' é, então acredito que ele precisa incorporar em sua teoria uma abordagem mais robusta de orientação racional. (shrink)

In this review-paper, I focus on biopsychological foundations of geometric cognition. Starting from the Kant’s views on mathematics, I attempt to show that contemporary cognitive scientists, alike the famous philosopher, recognize mutual relationships of visuospatial processing and geometric cognition. What I defend is a claim that Tinbergen’s explanatory questions are the most fruitful tool for explaining our “hardwired,” and thus shared with other animals, Euclidean intuitions, which manifest themselves in spatial navigation and shape recognition. I claim, however, that these “hardwired (...) intuitions” cannot capture full-blooded Euclidean geometry, which demands practice with cultural artifacts in various time-scales. (shrink)

In Ch. 6, I presented a model, which illustrates how belief in God could have warrant; my aim in the next four chapters is to extend the model of Ch. 6 to specifically include Christian belief, and to show how it can be that Christians can be justified, rational, and warranted in holding full‐blooded Christian belief. Now, one important difference between bare theism and Christianity has to do with sin and the divine remedy proposed for it; in the (...) present chapter, therefore, I explore the nature of sin and its noetic effects. After providing an initial statement of the extended A/C model, I turn to an examination of the nature of sin, focusing especially on original sin, a condition affecting both will and intellect. According to the extended A/C model, the noetic effects of sin are concentrated with respect to our knowledge of others, ourselves, and God; most importantly, the sensus divinitatis has been damaged by sin. After exploring this basic noetic consequence of sin, I return to an issue from Ch. 12 of Warrant and Proper Function, and take the opportunity to make some corrections, simplifications, and additions to the arguments I offered there.

The argument from the claim to correctness has been put forward by Robert Alexy to defend the view that normative utterances admit of objective answers. My purpose in this paper is to preserve this initial aspiration even at the cost of diverting from some of the original ideas in support of the argument. I begin by spelling out a full-blooded version of normative cognitivism, against which I propose to reconstruct the argument from the claim to correctness. I argue (...) that the context of uttering normative propositions points to the possibility of normative cognition, but does not constitute it. What constitutes the possibility of cognition is, as of necessity, the propositional structure of norms. I conclude that the argument from the claim to correctness ought to safeguard a distinction between the context of uttering a normative sentence and the proposition that individuates the content of the utterance.

In chapter one I consider two arguments for the claim that we ought to attribute linguistic knowledge to speakers of a natural language. The a priori argument has it that a theory of understanding reveals what it is that speakers of a language know about their language. The second argument takes the form of an inference to the best explanation, emphasising the idea that speaking and understanding a language is a rational activity carried on by agents with intention and purpose. (...) Linguistic knowledge is attributed to speakers as a way of making such a practice intelligible. ;In chapter two, I examine the several sceptical worries and substantive objections that have been raised to the idea of linguistic knowledge. None of these objections is fatal; rather they direct our attention to the need to specify what kind of knowledge linguistic knowledge is. ;In chapter three I argue that we do best to think of the notion of implicit linguistic knowledge as a "place-holder". ;In chapter four, I turn to a discussion of implicit belief, drawing a distinction between the way in which the content of a belief might be represented in an agent's brain and the kind of access she has to that content. I argue against an account of implicit belief that is motivated by concerns about representation, and for one that focuses on the kind of access an agent has to her implicit beliefs. ;In chapter five I attempt to sketch an account of implicit linguistic knowledge that fulfills its explanatory agenda while avoiding the objections discussed in earlier chapters. A speaker's implicit linguistic knowledge, understood as a set of articulated psychological states, grounds her full-blooded linguistic dispositions. This analysis of implicit linguistic knowledge is not subject to standard objections to that notion. Furthermore, it provides a "non-reductive" explanation of a speaker's language mastery, since it holds a middle ground between strictly biological, or neurophysiological accounts and purely behavioristic accounts of what makes an agent a speaker of a language. ;Finally, I take up the question of whether Dummett can accept my account of implicit linguistic knowledge.

Are there, in addition to the various actual objects that make up the world, various possible objects? Are there merely possible people, for example, or merely possible electrons, or even merely possible kinds? We certainly talk as if there were such things. Given a particular sperm and egg, I may wonder whether that particular child which would result from their union would have blue eyes. But if the sperm and egg are never in fact brought together, then there is no (...) actual object that my thought is about.1 Or again, in the semantics for modal logic we presuppose an ontology of possibilia twice over.2 For first, we countenance various possible worlds, in addition to the actual world; and second, each of these worlds is taken to be endowed with its own domain of objects. These will be the actual objects of the world in question, but they need not be actual simpliciter, i.e., actual objects of our world. What are we to make of such discourse? There are four options: (i) the discourse is taken to be unintelligible; (ii) it is taken to be intelligible but nonfactual, i.e. as not in the business of stating facts; (iii) it is taken to be factual but reducible to discourse involving no reference to possibilia; (iv) it is taken to be both factual and irreducible.3 These options range from a fullblooded form of actualism at one extreme to a full-blooded form of possibilism at the other. The two intermediate positions are possibilist in that they accept the intelligibility of possibilist discourse but actualist in that they attempt to dispense with its prima facie commitment to possibilia. All four positions have found advocates in the literature. Quine, in his less irenic moments, favors option (i); Forbes ([85], p. 94) advocates option (ii), at least for certain parts of possibilist discourse; many philosophers, including Adams [74] and myself, opt for (iii); while Lewis [86] and Stalnaker [75] have endorsed versions of (iv), that differ in how full-blooded they take the possible objects to be. My focus in the present article is on the third option.. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Michael’s Story or the Paradox of NormalcyMichael KreuzerI was born in Montreal in 1974. My parents were both “older.” My mother was almost 45; my father was in his 50’s. I have a sister who is six years older than me. What I know about my mother’s prenatal care is that it was quite basic.I was premature. My mother’s due date was in mid–August, however I showed up about (...) three weeks earlier. I know that initially upon my birth I was declared male. However, upon closer examination, a few “abnormalities” of my genitals were found. I urinated through a small hole at the base of my penis; adjacent to this hole was another opening, barely big enough for a Q–tip. My scrotum was empty; my gonads had not descended.The doctors who examined me decided that they could not assign a gender without further testing. They told my mother I would need to remain in the hospital until such testing was completed. Apparently not being able to determine sex/gender is a life–threatening condition that requires hospitalization.It was determined that I had a uterus and it was presumed that my undescended gonads were ovaries (not verified by biopsy). There was a small vaginal opening behind my small urethral opening. Structures such as the labia were not developed. I found out later my vagina had fistulated into both my urethra and my perineum. Karyotyping was performed resulting in 46,XX with a diagnosis of female pseudo–hermaphroditism. My parents were informed that in spite of my external genitalia I was female and I would never develop as a male. I would require “corrective surgeries” which should be performed as soon as possible so I would not have any issues with my gender identity. They were even told that I would be able to become pregnant if I had the surgeries. In fact, I never ovulated and I have a small unicornuate uterus.My father refused all surgeries on my behalf most likely because he was a full–blooded Navajo who had suffered from abuse in an Indian boarding school during his childhood in New Mexico. His family was traditional, and because they didn’t adapt to prevailing Christian values, he and several of his siblings were removed from their parents. My dad was the oldest of 12 children and by the time his youngest siblings were born, the practice to take children away from their families had been changed.I think my father was deeply traumatized by his childhood and did not associate much with his family, nor did he want to visit the reservation. He spoke the language but never encouraged us to learn it. He did teach us some of the traditions. He told me about the nadleh, which is the other gender besides male and female in the Navajo tradition. There are two kinds of nadleh, which are almost like male–to–female and female–to–male transsexuals. Mostly I educated myself later and learned about the Navajo belief system in which the creation story is an important part. In the Navajo tradition, the creation story tells of First Man and First Woman; the first children born to them are the Hermaphrodite Twins. [End Page E7]My father was a US Army Master Sergeant, which was an unusual career for a man of his origins; he was a veteran of the Second World War. After he left the army he took his family to Montreal where he had a job in security. I think he preferred to live outside the U.S. He used to say that in Germany, where he had managed to stay for a long time while serving in the Army, he was just another American soldier. In spite of his career, he had a deep mistrust for “white people.” I remember he used to say that he was in the Army because this was his country long before the white people came and he loved it. He did not love the people who governed it. All this very much played into the decision not to listen to the doctors’ recommendations about surgery. My... (shrink)

Anscombe's indictment of modern moral philosophy is full-blooded. She began with three strong claims: The first is that is not profitable to do moral philosophy… until we have an adequate philosophy of psychology, in which we are conspicuously lacking. The second is that the concepts of obligation and duty… and of the moral sense of ‘ought’, ought to be jettisoned… because they are derivatives… from an earlier conception of ethics… and are only harmful without it. The third thesis (...) is that the differences between the well-known English writers on moral philosophy from Sidgwick to the present are of little importance. (shrink)

In what ways should we include future humanoid robots, and other kinds of artificial agents, in our moral universe? We consider the Organic view, which maintains that artificial humanoid agents, based on current computational technologies, could not count as full-blooded moral agents, nor as appropriate targets of intrinsic moral concern. On this view, artificial humanoids lack certain key properties of biological organisms, which preclude them from having full moral status. Computationally controlled systems, however advanced in their cognitive (...) or informational capacities, are, it is proposed, unlikely to possess sentience and hence will fail to be able to exercise the kind of empathic rationality that is a prerequisite for being a moral agent. The organic view also argues that sentience and teleology require biologically based forms of self-organization and autonomous self-maintenance. The organic view may not be correct, but at least it needs to be taken seriously in the future development of the field of Machine Ethics. (shrink)

Can there be a state which is both a belief and a desire? More exactly, a state which is a belief that p and a desire that q, where p and q may be the same proposition or a different one? Such a state would be a ‘besire’. So a first question is the general question whether besires are possible. Normative attitudes would be good candidates for besires. For example, if Sandra has the normative attitude that it would be best (...) for her to leave the country, this seems to be a propositional state of hers which may be both a belief and a desire. Or, for another example, suppose that Michael has the normative attitude that one should not lie without good reason. Then he seems to hold a belief about lying, namely, that lying without good reason is normatively forbidden, and, at the same time, he also seems to have a desire with respect to lying, namely, the desire not to lie without good reason. A second question is whether normative attitudes are besires.1 There are other good candidates for besires. A ‘simple’ state like the state of the young chicken expressed by its cry may be a case in point. Even though the chicken’s state is probably not a full-blooded propositional state, it seems to be ‘Janus-faced’ as well. Does it descriptively represent the chicken’s hunger? Or is it a desire for food? Maybe both – and then it could be a besire, or something like that.2 Ruth Garrett Millikan mentions another candidate, namely, intentions. Intentions clearly have a desire-like nature. And arguably, they.. (shrink)

Abstract: Open-mindedness is typically at the top of any list of the intellectual or "epistemic" virtues. Yet, providing an account that simultaneously explains why open-mindedness is an epistemically valuable trait to have and how such a trait is compatible with full-blooded belief turns out to be a challenge. Building on the work of William Hare and Jonathan Adler, I defend a view of open-mindedness that meets this challenge. On this view, open-mindedness is primarily an attitude toward oneself as (...) a believer, rather than toward any particular belief. To be open-minded is to be aware of one's fallibility as a believer, and to acknowledge the possibility that anytime one believes something, one could be wrong. In order to see that such an attitude is epistemically valuable even to an already virtuous agent, some details of the skills and habits of the open-minded agent are elucidated. (shrink)
