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' 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. Adam Olszewski, is assistant professor of the philosophy of mathematics and mathematical logic at the Department of Philosophy of Pontifical Academy of Theology, Cracow (Poland). Jan Wolenski is professor of philosophy, Institute of Philosphy, Jagiellonian University, Cracow (Poland). He is one of the most distinguished logicians in Poland. Robert Janusz is assistant professor in the Department of Philosophy of Ignatius College, Cracow (Poland). (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)

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)

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)

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?

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)

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)

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)

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.

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)

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)

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)

Memory, mother of the Muses by Zeus, has nurtured culture for nearly three millennia while her nemesis, forgetfulness, has been demonized as an agent of destruction. In the modern age, however, memory has grown increasingly burdensome, opening the way for a more positive assessment of forgetfulness. Nietzsche praises animals for an inability to remember that preserves their innocence and happiness, and Freud documents the discontents of a civilization that cannot forget. ;In tracing the recent development of these issues, the dissertation (...) focuses primarily on Walter Benjamin, Hans Blumenberg, and Thomas Pynchon. Benjamin and his anguished "angel of history" show the destructive psychological effects of trying to use human memory as a secular form of redemption. Blumenberg's philosophy of history makes it possible to trace memory's responsibility for redemption to the modern age's inflated notion of the subject. Blumenberg's work also emphasizes the importance of metaphor and narrative in mediating and creating historical understanding, and this aesthetic distance weakens memory's redemptive relation to the past. Pynchon's protagonists, too, find that their desire to make historical meaning fully present is overshadowed by their fear of such presence. By reconciling themselves to a profane aesthetic distance from the past, Blumenberg and Pynchon redeem themselves from the melancholy engendered by an overly ambitious memory. ;Thus the dissertation attempts to recover a more modest and less oppressive memory by understanding it as a way to distance rather than redeem past injustices. This reconception of the function of memory helps establish an equilibrium between the pensive memory of Benjamin's "angel of history" and the innocent oblivion of Nietzsche's animals. ;In addition to the three major figures named in the title, the dissertation devotes sections and excursuses to Friedrich Nietzsche, Sigmund Freud, Ernst Cassirer, Martin Heidegger, Virginia Woolf, Ernst Robert Curtius, Elie Wiesel, Primo Levi, Michel Foucault, and Thomas Kuhn. Translations of two essays by Blumenberg, "Pensiveness" and "Being--A MacGuffin," and a comprehensive Blumenberg bibliography are included as appendices. (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.

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.

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.

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)

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 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)

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)

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.

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.

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. (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. (shrink)

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)

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 attitudpaes, 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 and Marc Moffett and Carlotta Pavese 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)

Humanism is the traditional approach in many disciplines, including history, philosophy, anthropology, and sociology. Humanists tend to assume that there is an important distinction between the knowing subject and the rest of the world. Posthumanism challenges this assumption, asking us to examine how the distinction between subject and object is constructed in the first place. To do so, posthumanists argue that we must abandon our traditional resources for understanding the knowing subject. In its place, we must adopt a radical new (...) notion of agency that encompasses humans and nonhumans. This paper argues that, although posthumanism teaches us a valuable lesson, the real problem lies not with humanism, but with Cartesianism. To show this, I develop a new version of humanism by drawing on two anti-Cartesian strands within recent philosophy of mind: _the extended mind thesis_ and _mental fictionalism_. The result is a view that allows us to retain our traditional resources for understanding the knowing subject, while recognising that the nature of that subject can change over time. (shrink)

This chapter takes a closer look at the relationship between belief and judgment. It presents an argument for the output thesis—the thesis that conscious judgments give rise to occurrent beliefs. It is then suggested that the output thesis provides independent support for the transparency method and an independent explanation of why Moore’s Paradox arises. The output thesis stands in contrast to other views in the literature which do not posit such a close connection between judgment and (...) belief. Along the way, some of the implications of the output thesis for current characterizations of judgment and belief are discussed. Finally, a significant objection to the output thesis is considered—namely, the set of cases where subjects assert that P but behave in ways that suggest they believe not-P. It is argued that such cases do not undermine the output thesis. (shrink)

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)

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 main purpose of this paper, which takes the form of an essay, is an attempt to answer the question of the limits of artificial intelligence (AI). In the introductory section, we present the key milestones in AI development, both historical and future projections, in which two terms – Artificial Human (AH) and Artificial ‘god’ (AG) – play a special role. In the second section, we clarify the question of the limits of AI by indicating the hypothetical goal of AI (...) development. The third section develops the argument proposed by C. F. Weizsäcker, originally formulated for cybernetics. The conclusion of this argument is optimistic about limitations to the possibilities of cybernetic simulations. We apply this argument to AI and subject it to a critique which ultimately undermines the legitimacy of its conclusion. We base the critique on two well-known results: the theorem of the unsolvability of the halting problem and Gödel’s first incompleteness theorem, and we formulate two objections interpreted without adopting Church’s thesis. In the crucial fourth section, we present a third objection in the form of a hypothesis for which we argue that AI (AH), understood as a subject, will always be solipsistic. (shrink)

This paper argues that many of our most important theories of retributivism are unwittingly committed to the radical thesis that prepunishment—punishment before an offense—is morally permissible. From the perspective of diachronic justice on which these theories crucially depend, the timing of retribution is, ceteris paribus, irrelevant. But retributivism’s counterintuitive support does not stop there: there are conditions under which pre-offense apprehension and punishment guarantees a higher probability of justice being done. Under these conditions, the popular retributive theories I have (...) in mind do not just permit, but require, prepunishment. (shrink)

The reception of the heliocentric theory of Nicolaus Copernicus in Jewish thought of the 17th-century period is a good exemplification of the issue concerning the formation of the relationship between natural science and theology, or more broadly: between science and religion. The fundamental question concerning this relationship, which we can ask from today’s perspective of this problem, is: How does it happen that claims of a scientific nature, which are initially considered from a religious point of view to be incompatible (...) with the religious view of the world, are later accepted as possible to agree with this image of reality and are assimilated by a given religion? Based on the reception of the Copernican image of the universe by two representatives of Jewish philosophy in the 17th century—David Gans and Joseph Solomon Delmedigo—it is possible to trace this process and pose the thesis that it takes place according to two strategies. Within the framework of the first one, represented by Gans, in a situation of incompatibility between the scientific and religious images of nature, a scientific theory is sought that explains the observed phenomena and, on the other hand, satisfies the religious claims. Finding such a theory solves the problem of the incompatibility mentioned above of images of the world, gives the theory credibility from the religious point of view and constitutes an argument for its correctness. The second strategy, represented by Delmedigo, consists in refraining from pursuing a direct, immediate, and unequivocal reconciliation of the two images of the world while at the same time recognizing a properly justified scientific theory as correctly describing and explaining the phenomena occurring in nature. Consequently, the apparent incompatibility between the scientific and the religious worldview demands either a reformulation of religious statements in such a way as to remove this incompatibility or the restriction of the meaning of religious statements to the strictly religious and moral sphere, without the ambition to speak about nature. In either case, however, it is already a task for the representatives of the religion concerned who, when confronted with adequately justified scientific claims, to avoid exposing their religion to the accusation that its claims are unreasonable and anachronistic, undertake the task mentioned above of modifying or limiting the scope of their statements. It seems that in the representatives of Jewish thought and Judaism, who are the successors of Gans and Delmedigo, generally speaking, the second strategy has prevailed in this version, in which one abandons the claim of religion to statements about the material world at the price of a significant divergence of the paths of science and religion. Consequently, it treats them as different narratives, describing and explaining two separate spheres of reality. (shrink)

The concepts of knowledge and accomplishment are duals. There are many parallels between them. In this paper I discuss the "AA" thesis, which is dual to the well known KK thesis. The KK thesis claims that if someone knows something, then she knows that she knows it. This is generally thought to be false, and there are powerful reasons for rejecting it. The AA thesis claims that if someone accomplishes something, then she accomplishes that she accomplishes (...) it. I argue that this, too, is false, and that the reasons it is false parallel reasons for the falsity of the KK thesis. (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)

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)

I contend that hope can be of significant value to individuals even as they acknowledge that there is no cure for their affliction. In particular, I argue that it is good for such patients to hope for (i) a meaningful quality of life in their remaining days and (ii) a good death. If this thesis is on target, then there is an important place for clinicians to employ the language of hope with reference to ends other than a cure. (...) I then conclude with a few schematic comments on how the clinical aims discussed here might figure in a broader understanding of hope as a virtue. (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)

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.

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)

Aim of this paper was to fi nd and explicate similarities between science and religion with respect to classical criteria of scientifi cognition. The discourse was led within the following aspects: knowledge, method, language, institution and limits. The derived conclusion is that religion can be interpreted as satisfying all general conditions of scientific enterprise. Such a conclusion is interpreted as supporting two possible thesis: (1) religion as a scientifi c discipline ought to be implemented into scientific enterprise in the (...) way of interdisciplinary cooperation; (2) the presented similarity remains constructed, not discovered – there is no sense in comparing religion to science, since these two notions are too general and vague. Regardless which interpretation one would prefer, it shows, that anti-theistic arguments based on showing religion as opposed to science, does not sounds. (shrink)

It is common to encounter the criticism that Joseph Raz’s service conception of authority is flawed because it appears to justify too much. This essay examines the extent to which the service conception accommodates this critique. Two variants of this critical strategy are considered. The first, exemplified by Kenneth Einar Himma, alleges that the service conception fails to conceptualize substantive limits on the legitimate exercise of authority. This variant fails; Raz has elucidated substantive limits on jurisdiction within the service conception (...) of authority, albeit reluctantly and equivocally. The second, exemplified by Scott Hershovitz, alleges that the service conception fails to conceptualize procedural limits on the legitimate exercise of authority. He objects that the normal justification thesis fails to deny legitimacy to rational and expert dictators. This argument is more potent, but its force is concealed when it is aimed at the normal justification thesis rather than the quite separate jurisdictional limits of Raz’s theory. Clarifying those jurisdictional aspects of the service conception shows why the first argument fails and exposes the real strength of the second. Both variants have important consequences for our understanding of the service conception. (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)
