The question is whether Urmson's account depicts Austin's method needs a qualified answer. Roughly, the answer is that what it presents is not Austin's method because it is not the whole of Austin's method. Urmson confines his attention to aspects of the inner structure of the method and leaves out the question of its motivation and possible aims.

I argue that a slight shift in our understanding of the notion of existence is needed in order to cope with the problem of external world and the problem of mind and body. As a consequence of it being taught by "givenness" of the subjective mind, and despite its applicability in objective contexts, it should be considered a "tool" akin to qualia, rather than pertaining to a "true", objective reality. In plain language, one's supposed relation with their surroundings is known (...) to them only in terms of their private ontology. This conclusion is supported both by intuition and - perhaps most importantly - by ontological issues in quantum physics. (shrink)

This paper examines three cases of the clash between science and philosophy: Zeno’s paradoxes, the Frame Problem, and a recent attempt to experimentally refute skepticism. In all three cases, the relevant science claims to have resolved the purported problem. The sciences, construing the term broadly, are mathematics, artificial intelligence, and psychology. The goal of this paper is to show that none of the three scientific solutions work. The three philosophical problems remain as vibrant as ever in the face of robust (...) scientific attempts to dispel them. The paper concludes by examining some consequences of this persistence.

In this paper, I discuss the relationship between bodily experiences in dreams and the sleeping, physical body. I question the popular view that dreaming is a naturally and frequently occurring real-world example of cranial envatment. This view states that dreams are functionally disembodied states: in a majority of dreams, phenomenal experience, including the phenomenology of embodied selfhood, unfolds completely independently of external and peripheral stimuli and outward movement. I advance an alternative and more empirically plausible view of dreams as weakly (...) phenomenally-functionally embodied states. The view predicts that bodily experiences in dreams can be placed on a continuum with bodily illusions in wakefulness. It also acknowledges that there is a high degree of variation across dreams and different sleep stages in the degree of causal coupling between dream imagery, sensory input, and outward motor activity. Furthermore, I use the example of movement sensations in dreams and their relation to outward muscular activity to develop a predictive processing account. I propose that movement sensations in dreams are associated with a basic and developmentally early kind of bodily self-sampling. This account, which affords a central role to active inference, can then be broadened to explain other aspects of self- and world-simulation in dreams. Dreams are world-simulations centered on the self, and important aspects of both self- and world-simulation in dreams are closely linked to bodily self-sampling, including muscular activity, illusory own-body perception, and vestibular orienting in sleep. This is consistent with cognitive accounts of dream generation, in which long-term beliefs and expectations, as well as waking concerns and memories play an important role. What I add to this picture is an emphasis on the real-body basis of dream imagery. This offers a novel perspective on the formation of dream imagery and suggests new lines of research. (shrink)

This paper analyzes the apraxia argument in Cicero’s Academica. It proposes that the argument assumes two modes: the evidential mode maintains that skepticism is false, while the pragmatic claims that it is disadvantageous. The paper then develops a tension between the two modes, and concludes by exploring some differences between ancient and contemporary skepticism.

In this dissertation I consider the problem of external world skepticism and attempts at providing an argument to the best explanation against it. In chapter one I consider several different ways of formulating the crucial skeptical argument, settling on an argument that centers on the question of whether we're justified in believing propositions about the external world. I then consider and reject several options for getting around this issue which I take to be inadequate. I finally conclude that the best (...) option available to us at the moment is to argue that the antiskeptical view is the best explanation of our ordinary experiences In chapter two I argue that, if we hope to ground what counts as defending antiskepticism in common sense, there is an argument against the possibility of ever knowing one has succeeded in defending antiskepticism. After showing that common sense is no place to look in setting a goal for our antiskeptical project, I present the view that what will be crucial to settling on our antiskeptical goal is coming to a successful analysis of the nature of physical objects. I suggest some minimal criteria that must be met by a view in order to be antiskeptical based on our intuitions about core skeptical cases, but acknowledge that a fully successful response to external world skepticism will require the antiskeptic to engage in some much more difficult analysis. In chapter three I consider various views of the nature of explanation and conclude, tentatively, that explanation as it interests the antiskeptic is fundamentally causal. In chapter four I consider and reject some of the core views on which best explanation facts are so fundamental that a project of attempting to vindicate probabilistically the virtues which make explanations epistemically good. In this chapter I show that views which analyze justification in terms of best explanation factors fail. In chapter five I attempt to vindicate the various explanatory virtues probabilistically. In doing so I attempt to express or translate the various explanatory virtues in terms of probabilities in order to show that having those virtues makes a view at least prima facie more probable. In chapters six and seven I explain and evaluate the various arguments to the best explanation against skepticism present in current philosophical literature. I attempt to show that extant arguments fail to appreciate the virtues possessed by classical skeptical scenarios. In chapter eight I briefly consider some options that may be open to the antiskeptic moving forward. All routes forward contain considerable obstacles, but there are some fruitful areas of research to pursue. (shrink)

Extended Rationality: A Hinge Epistemology provides a novel account of the structure of epistemic justification. Its central claim builds upon Wittgenstein's idea in On Certainty that epistemic justifications hinge on some basic assumptions and that epistemic rationality extends to these very hinges. It exploits these ideas to address major problems in epistemology, such as the nature of perceptual justifications, external world skepticism, epistemic relativism, the epistemic status of basic logical laws, of the Principle of the Uniformity of Nature, of our (...) belief in the existence of the past and of other minds, and the nature of testimonial justification. Along the way, further technical issues, such as the scope of the Principle of Closure of epistemic operators under known entailment, the notion of transmission failure, and the existence of entitlements are addressed in new and illuminating ways.

Skeptical hypotheses such as the brain-in-a-vat hypothesis provide extremely poor explanations for our sensory experiences. Because these scenarios accommodate virtually any possible set of evidence, the probability of any given set of evidence on the skeptical scenario is near zero; hence, on Bayesian grounds, the scenario is not well supported by the evidence. By contrast, serious theories make reasonably specific predictions about the evidence and are then well supported when these predictions are satisfied.

For beings like us, no ontological argument can possibly succeed. They are doomed to fail. The point of an ontological argument is to enable nonempirical knowledge of its conclusion, namely, that God exists. But no ontological argument could possibly enable us to know its conclusion nonempirically, and so must fail in that sense.

Hilary Putnam has offered two arguments to show that we cannotbe brains in a vat, and one to show that our cognitive situationcannot be fully analogous to that of brains in a vat. The latterand one of the former are irreparably flawed by misapplicationsof, or mistaken inferences from, his semantic externalism; thethird yields only a simple logical truth. The metaphysical realismthat is Putnams ultimate target is perfectly consistent withsemantic externalism.

This essay deals with a selected part of an epistemological controversy provided by Tūsī in response to the skeptical arguments reported by Rāzī that is related to what might be called "intellectual skepticism," or skepticism regarding the judgments of the intellect, particularly in connection with self-evident principles. It will be shown that Rāzī has cited and exposed a position that seems to be no less than a medieval version of empiricism. Tūsī, in contrast, has presented us with a position that (...) rejects such empiricism. The comparative aim of this essay is to draw attention to some similarities as well as some points of divergence between the kind of skeptical debate we are focusing on here, and some relevant epistemological discussions in the later traditions in the West.

Abstract The debate in the philosophy of perception between direct realists and representationalists should influence the debate in epistemology between internalists and externalists about justification. If direct realists are correct, there are more consciously accessible justifiers for internalists to exploit than externalists think. Internalists can retain their distinctive internalist identity while accepting this widened conception of internalistic justification: even if they welcome the possibility of cognitive access to external facts, their position is still quite distinct from the typical externalist position. (...) To demonstrate this, Alvin Goldman’s critique of internalism is shown to ignore important lessons from the case for direct realism about perception. In particular, it unjustifiably assumes that internalism entails that only facts simultaneous with the justification of a belief can justify the belief. Goldman’s definition of a “justifier” is also inconsistent with the overall guidance conception of epistemology he takes for granted in his critique of internalism.

According to epistemic internalism, the only facts that determine the justificational status of a belief are facts about the subject’s own mental states, like beliefs and experiences. Externalists instead hold that certain external facts, such as facts about the world or the reliability of a belief-producing mechanism, affect a belief’s justificational status. Some internalists argue that considerations about evil demon victims and brains in vats provide excellent reason to reject externalism: because these subjects are placed in epistemically unfavorable settings, externalism (...) seems unable to account for the strong intuition that these subjects’ beliefs are nonetheless justified. I think these considerations do not at all help the internalist cause. I argue that by appealing to the anti-individualistic nature of perception, it can be shown that skeptical scenarios provide no reason to prefer internalism to externalism. (shrink)

Discussion about the application of scientific knowledge in robotics in order to build people helpers is widespread. The issue herein addressed is philosophically poignant, that of robots that are “people”. It is currently popular to speak about robots and the image of Man. Behind this lurks the dialogical mind and the questions about the significance of an artificial version of it. Without intending to defend or refute the discourse in favour of ‘recreating’ Man, a lesser familiar question is brought forth: (...) “and what if we were capable of creating a very convincible replica of man (constructing a robot-person), what would the consequences of this be and would we be satisfied with such technology?” Thorny topic; it questions the entire knowledge foundation upon which strong AI/Robotics is positioned. The author argues for improved monitoring of technological progress and thus favours implementing weaker techniques. (shrink)

It is widely believed that Twin-Earth-style thought experiments show that the contents of a person's thoughts fail to supervene on her intrinsic properties. Several recent philosophers have made the further claim that Twin-Earth-style thought experiments produce metaphysically necessary conditions for the possession of certain concepts. I argue that the latter view is false, and produce counterexamples to several proposed conditions. My thesis is of particular interest because it undermines some attempts to show that externalism is incompatible with privileged access.

Semantic externalism Are the meanings of natural kind words, such as “water” or “tiger,” in the head or in the world? This question is pressing and controversial in contemporary philosophy. The nature of the meaning related to propositional contents and words of the natural kind raises a fundamental disagreement between two groups of philosophers: defenders of internalism and defenders of externalism. The two groups differ on how to define meaning. Internalists say that meaning is determined entirely by aspects that are (...) internal to the speaker, and mental contents are semantic contents that are in our minds or heads, their slogan is “Meanings are in the head or brain.” Externalists say that meaning is determined, at least in part, by aspects that are external to the speaker, and that contents are linguistic signs and exist in the outside world, and their slogan is “Meanings do not exist only in the head.” In this article, I want to shed explanatory light on this disagreement by examining its origins, explaining some of the arguments in support of externalism, and demonstrating the impact of this disagreement on understanding the nature of meaning. This article addresses several topics: 1. Various types of externalism 2. Description theory and causal theory 3. Hillary Betnam and Twin Earth thought experiment 4. Tyler Berg and arthritis argument 5. Donald Davidson and perceptual externalism 6.

‘Semantic externalism’ is the view that the thought and speech of internally identical subjects can have different contents, depending on facts about their environments. ‘Semantic internalism’ is the negation of this view. The details of these two views depend on the definition of ‘internal identity’. Katalin Farkas has shown that the traditional definition of internal identity as physical identity is too permissive: it misclassifies certain bodily states as internal. She has proposed defining internal identity as phenomenal identity instead. In the (...) critical part of my paper, I argue that Farkas’s proposal fails for being too restrictive: it misclassifies non-conscious mental states, most notably dispositional belief, as external. I consider two interpretations of Farkas’s proposal but conclude that neither succeeds, because each requires internal features to influence the subject’s phenomenal life in a way in which dispositional belief does not. In the constructive part of my paper, I consider dispositional identity as an alternative definition of internal identity. I argue that the dispositional-identity definition avoids the phenomenal-identity definition’s shortcoming and retains its main attraction, viz., that of securing the subjective indistinguishability that obtains between Twin Earth duplicates. My argument that it does the latter, however, faces potentially decisive obstacles. Thus, I retreat to a disjunctive proposal: internal identity should be defined either as dispositional identity or as dispositional-plus-phenomenal identity. I conclude by defending my proposal against a different charge that may be levelled against it, viz., that of misclassifying Cartesian dualism as an externalist theory of the mind. (shrink)

Epistemic Logic is our basic universal science, the method of our cognitive confrontation in reality to prove the truth of our basic cognitions and theories. Hence, by proving their true representation of reality we can self-control ourselves in it, and thus refuting the Berkeleyian solipsism and Kantian a priorism. The conception of epistemic logic is that only by proving our true representation of reality we achieve our knowledge of it, and thus we can prove our cognitions to be either true (...) or rather false, and otherwise they are doubtful. Therefore, truth cannot be separated from being proved and we cannot hold anymore the principle of excluded middle, as it is with formal semantics of metaphysical realism. In distinction, the intuitionistic logic is based on subjective intellectual feeling of correctness in constructing proofs, and thus it is epistemologically encapsulated in the metaphysical subject. However, epistemic logic is our basic science which enable us to prove the truth of our cognitions, including the epistemic logic itself. (shrink)

In this essay I try to give some overall statements in order to show that new realism is to be understood as a kind of positive philosophy. Against constructivism, I argue that there is a prevalence of the objects themselves on our understanding of them because reality offers a resistance to our attempt to grasp it depending on its level of dependence from our own understanding, which is different in the case of natural objects, ideal object and social object. This (...) negativity leads to an ontological necessity of facticity. In the second part of this paper I will describe – through the exposition of three key concepts of new realism, i.e. “unamendability”, “interaction” and “affordance” – an ascending path for which the negative and the resistance turn into positivity.

I extend my direct virtue epistemology to explain how a knowledge-first framework can account for two kinds of positive epistemic standing, one tracked by externalists, who claim that the virtuous duplicate lacks justification, the other tracked by internalists, who claim that the virtuous duplicate has justification, and moreover that such justification is not enjoyed by the vicious duplicate. It also explains what these kinds of epistemic standing have to do with each other. I argue that all justified beliefs are good (...) candidates for knowledge, and are such because they are exercises of competences to know. However, there are two importantly different senses in which a belief may be a good candidate for knowledge, one corresponding to an externalist kind of justification and the other corresponding to an internalist one. I show how the account solves the new evil demon problem in a more satisfactory way than existing accounts. We end up with a view of knowledge, justification, and rationality that is plausible, motivated, and theoretically unified. (shrink)

This is an extended intellectual obituary for Hilary Putnam.

There is a considerable effort in current theorizing about psychological phenomena to eliminate minds and selves as a vestige of folk theories. The pertinent strategies are quite varied and may focus on experience, cognition, interests, responsibility, behavior and the scientific explanation of these phenomena or what they purport to identify. The minimal function of the notion of self is to assign experience to a suitable entity and to fix such ascription in a possessive as well as a predicative way. It (...) is usually argued that Hume formulated an empiricist account of experience that obviated the need for reference to selves; and recent arguments mustered by Derek Parfit claim to show how to preserve experience, interest, responsibility usually assigned selves and persons without invoking any such entities. The argument here advanced demonstrates that Hume actually concedes the minimal use of the notion of self, that there appear to be no convincing grounds for eliminating it, that there are critical uses for the notion that render it ineliminable, that admission is neutral regarding the nature of selves, and that Parfit''s arguments in particular fail. There appear, therefore, to be no empiricist or materialist grounds for the eliminative move. A large recent literature that favors various eliminative strategies is canvassed and shown to be inadequate to its task and unlikely (for principled reasons) to be able to achieve its eliminative objective.

Representationalism is widely thought to grease the skids of ontological reduction. If phenomenal character is just a certain sort of intentional content, representationalists argue, the hard problem of accommodating consciousness within a broadly naturalistic view of the world reduces to the much easier problem of accommodating intentionality. I argue, however, that there’s a fatal flaw in this reasoning, for if phenomenal character really is just a certain sort of intentional content, it’s not anything like the sort of intentional content described (...) by our best naturalistic theories. These theories make intentional content a mere Cambridge property of intentional states, a property that can be gained or lost through changes to distinct and causally disconnected objects. But consciousness is manifestly not like this; consciousness cannot suffer a mere Cambridge change. Thus, whatever ground is gained by explaining the phenomenal in terms of the intentional is lost again by undermining our best attempts to explain the intentional in terms of the natural. A Pyrrhic victory at best. (shrink)

P.F. Strawson in “Freedom and Resentment” argues that it is self-contradictory for abnormality to be the universal condition. This argument is claimed by Paul Russell to be faulty because conflating abnormality and incapacity, there being no contradiction involved in incapacity being a universal condition. Russell’s critique has become the mainstream view, but it will be shown that from the first-person point of view, universal incapacity could not be any basis on which we could in practice modify our attitudes.

In the text the author tries to investigate Wittgenstein’s notions of action, practice and pragmatism in his book On Certainty. An attempt is made to sketch the criterion of Wittgenstein’s analysis of certainty and to define the crucial concepts such as world-picture, practice, certainty and justification. The analysis shows that Wittgenstein applies a specific form of pragmatic solution to the problem of justification, which after all, can and should be called a kind of pragmatismus. This is the subject of the (...) first and the second part of the text. The third part shows the application of this pragmatic theory of justification to Wittgenstein’s refutation of scepticism. The author suggests that his pragmatic analysis of certainty presents an adequate means for the refutation of scepticism. However, his anti-scepticism is situated in the tradition of common sense and ordinary language philosophy and epistemology (Moore, Chisholm, Lehrer, Austin, Grice, Strawson, etc.). In the conclusion the author applies this anti-sceptical solution to the so called rule-following problem (as stated in Kripke’s work) and shows that there are some far reaching consequences of this interpretation of Wittgenstein’s later work to his position on language, learning, ontology and knowledge.

Zhuangzi’s Butterfly Dream story can be read as a skeptical response to the Cartesian Cogito, ergo sum solution, for it presents I exist as fundamentally unprovable, on the grounds that the notion about “I” that it is guaranteed to refer to something existing, which Descartes seems to assume, is unwarranted. The modern anti-skepticism of Hilary Putnam employs a different strategy, which seeks to derive the existence of the world not from some “indubitable” truth such as the existence of myself , (...) but from the meaning of some particular assertion I make. In this paper, I argue, however, that Putnam’s argument fails to deliver on the promise of showing the self-refuting nature of the skeptical hypothesis, as it relies on a double use of “I”, a fallacy of equivocation, reflecting an unsolved tension between the argument’s general premise, which is rather Zhuangzian in spirit, and his unwitting adoption of that unwarranted notion about “I”. I try to show further that the skepticism in Zhuangzi’s Butterfly Dream not only can be used to refute the proofs of the existence of the empirical I , but also is effective against accounts concerning the existence of the transcendental I.

The scandal to philosophy and human reason, wrote Kant, is that we must take the existence of material objects on mere faith . In contrast, the skeptical paradox that has scandalized recent philosophy is not formulated in terms of faith, but rather in terms of justification, warrant, and entitlement. I argue that most contemporary approaches to the paradox (both dogmatist/liberal and default/conservative) do not address the traditional problem that scandalized Kant, and that the status of having a warrant (or justification) (...) that is derived from entitlement is irrelevant to whether we take our beliefs on mere faith. For, one can have the sort of warrant that most contemporary anti-skeptics posit while still taking one’s belief on mere faith. An alternative approach to the traditional problem is sketched, one that still makes use of contemporary insights about “entitlement.”. (shrink)

Reductive physicalism is a minority view in contemporary philosophy as well as in science, and therefore arguments for endorsing it often amount to arguments against the alternative views, in particular so-called non-reductive physicalism. In this paper we put forward a new argument for reductive physicalism, according to which it is the best account of the empirical data that we have. In particular, we show that: (a) a reductive physicalist theory of the mind forms an essential part of the very argument (...) for the existence of an external world: if one rejects psychophysical identity physicalism, one’s case for believing in the existence of an external world is substantially weakened; and (b) the success of a physical account of the mind is the most important criterion for the success of (future) physics; and (c) reductive physicalism is the only approach in which relying on science in order to account for the external world makes sense; and finally, (d) within reductive physicalism, one can provide a new criterion for theory preference in science, and a new argument for scientific realism. In our physicalist view the experience forms the initial data, which is then reduced to fundamental physics. (shrink)

Images share a common feature with all phenomena of imagination, since they make us aware of what is not present or what is fictional and not existent at all. From this perspective, the philosophical approach of Kendall Lewis Walton—born in 1939 and active since the 1960s at the University of Michigan—is perhaps one of the most notable contributions to image theory. Walton is an authoritative figure within the tradition of analytical aesthetics. His contributions have had a considerable influence on a (...) broad range of topics, such as the role of categories in the understanding of the arts (Walton, “Categories of Art”. Philosophical Review, 79(3): 334–367, 1970), the ambiguous nature of emotions in the experience of fictional stories (Walton, “Fearing Fictions”. The Journal of Philosophy, 75(1): 5–25, 1978), the transparency of photographic images compared to other depictions (Walton, “Transparent Pictures: On the Nature of Photographic Realism”. Noûs, 18(1): 67–72, 1984) and, above all, the development of a general theory of fiction as imaginative activity. His 1990 book Mimesis as Make-believe: On the Foundations of the Representational Arts collects and re-elaborates articles Walton published on the subject since the 1970s. Though he does not attempt to give a definitive answer for what imagination is, Walton thoroughly investigates its role in all cases of representational works, describing depictions as a specific case of “make-believe” activity: images, in short, are specific props of a visual and perceptual “make-believe” game.

The traditional Turing test appeals to an interrogator's judgement to determine whether or not their interlocutor is an intelligent agent. This paper argues that this kind of asymmetric experimental set-up is inappropriate for tracking a property such as intelligence because intelligence is grounded in part by symmetric relations of recognition between agents. In place, it proposes a reciprocal test which takes into account the judgments of both interrogators and competitors to determine if an agent is intelligent. This form of social (...) interaction better tracks both the evolution of natural intelligence and how the concept of intelligence is actually used within our society. This new test is defended against the criticisms that a proof of intelligence requires a demonstration of self-consciousness and that semantic externalism entails that a non-embodied Turing test is inadequate.

Self-knowledge (SK) is a natural ability of the human cognitive system and is defined as a complex re-representation of knowledge subject has about her own internal states. It is composed of two basic representations: the representation of I and the representation of the experienced state. SK has a propositional (i.e. language-like) form and can be expressed in the form of self-reports like “I believe that I believe that p”. It has then the form of a second-order belief which, as a (...) re-representation, generates the following problem concerning false representations: if the first-order representations of the I or of experienced states can be false like in cases of self-illusions or disorders like somatoparaphrenia, then how can error in self-cognition inherited by the re-representation (i.e. by SK) be avoided? I claim that the re-representational model of SK is a useful but artificial tool for the description of the components of SK; however, it is misleading to think of it as capturing the truth about SK. I propose here a representational model of SK which reduces those beliefs constituting SK to first-order beliefs which are sufficient as constituents of SK. (shrink)

Can the early Yogācāra be said to present a systematic theory of meaning? The paper argues that Sthiramati’s bhāṣya on Vasubandhu’s Triṃśikā, in which he argues that all language-use is metaphorical, indeed amounts to such a theory, both because of the text’s engagement with the wider Indian philosophical conversation about reference and meaning and by virtue of the questions it addresses and its motivations. Through a translation and analysis of key sections of Sthiramati’s commentary I present the main features of (...) this theory of meaning and discuss the ways in which it is distinct from Vasubandhu’s ideas. I demonstrate how this theory of meaning enabled Sthiramati to present a unique understanding of discourse that distinguishes between varying levels of truth within the conventional realm. This understanding sat well with the Yogācāra soteriological and theoretical needs, and most importantly, enabled him to establish the meaningfulness of the school’s own metaphysical discourse. Securing this meaningfulness was especially important to Sthiramati in meeting the challenge posed by the radical conventionalism of the Madhyamaka, and his response as I interpret it suggests that one of the main disputes between the early Yogācāra with the Mādhyamika, at least as reflected in the Triṃśikā-bhāṣya, in fact turns on linguistic rather than ontological issues.

The paper begins by examining the original Turing Test (2T) and Searle’s antithetical Chinese Room Argument, which is intended to refute the 2T in particular, as well as any formal or abstract procedural theory of the mind in general. In the ensuing dispute between Searle and his own critics, I argue that Searle’s ‘internalist’ strategy is unable to deflect Dennett’s combined robotic-systems reply and the allied Total Turing Test (3T). Many would hold that the 3T marks the culmination of the (...) dialectic and, in principle, constitutes a fully adequate empirical standard for judging that an artifact is intelligent on a par with human beings. However, the paper carries the debate forward by arguing that the sociolinguistic factors highlighted in externalist views in the philosophy of language indicate the need for a fundamental shift in perspective in a Truly Total Turing Test (4T). It’s not enough to focus on Dennett’s individual robot viewed as a system; instead, we need to focus on an ongoing system of such artifacts. Hence a 4T should evaluate the general category of cognitive organization under investigation, rather than the performance of single specimens. From this comprehensive standpoint, the question is not whether an individual instance could simulate intelligent behavior within the context of a pre-existing sociolinguistic culture developed by the human cognitive type. Instead the key issue is whether the artificial cognitive type itself is capable of producing a comparable sociolinguistic medium. (shrink)

In this essay, I attempt to provide answers to the following four queries concerning the metaphysics of early human embryogenesis. (1) Following its first cellular fission, is it coherent to claim that one and only one of two “blastomeric” twins of a human zygote is identical with that zygote? (2) Following the fusion of two human pre-embryos, is it coherent to claim that one and only one pre-fusion pre-embryo is identical with that postfusion pre-embryo? (3) Does a live human being (...) come into existence only when its brain comes into existence? (4) At implantation, does a pre-embryo become a mere part of its mother? I argue that either if things have quidditative properties or if criterialism is false, then queries (1) and (2) can be answered in the affirmative; that in light of recent developments in theories of human death and in light of a more “functional” theory of brains, query (3) can be answered in the negative; and that plausible mereological principles require a negative answer to query (4).

Como posso estar certo de que existe qualquer coisa de externa aos meus próprios pensamentos? Muitos filósofos procuraram ou apresentar uma prova da existência do mundo externo, ou rejeitar a inteligibilidade da própria ideia de uma “prova” nesse contexto.

Blackwell, Malden, pp 231-250, 2005), Speaks (Philos Rev 114:359–398, 2005), and Crowther (Erkenntnis 65:5–276, 2006). They distinguish a ‘state’ reading and a ‘content’ reading of ‘(non)conceptual’ and argue that many arguments on either side support only the respective state views, not the respective content views. To prepare (...) the ground for my defense, I argue for an understanding of the state view in terms of concept exercise rather than concept possession and provide an overview of versions of conceptualism and nonconceptualism of different strengths. I then argue that conceptualists and nonconceptualists tacitly accept a so-called ‘state-to-content’ principle, show that existing defenses of this principle fail, and provide a new defense of it. It draws on the sources of the nonconceptualism debate, viz. the need to do justice both to the phenomenology of experience and to its epistemological role and to account for the existence of perceptual content and thought content. I argue that epistemological considerations together with considerations from the subject’s perspective support the claim that conceptual thought has conceptual and propositional content, whereas nonconceptual experience has nonconceptual and non-propositional content.

Ordinary knowledge claims are challenged by philosophical scepticism which holds that we are unable to exclude the possibilities of error involved in well-known sceptical alternatives . In order to explain how we can resist this challenge, first I compare philosophical and ordinary doubt. I point out that they do not differ in terms of the way they aim to undermine knowledge claims, but rather in the character of the alternatives to which they appeal. Thus, in ordinary contexts, philosophical sceptical alternatives (...) should not be considered relevant because they are farfetched, not supported by any indication that they really might exist in the given circumstances. Since this point concerns the assertability rather than the truth of our knowledge claims, I further argue that while our evidential basis for their assertability is internal, their truth depends upon certain assumptions concerning the causal history of our beliefs, reliability of our cognitive abilities, success in identifying and excluding relevant alternatives, etc. In everyday knowledge attributions, these assumptions operate as externalist preconditions so that we may know something only if they are correct even without knowing that they are correct. Finally, I point out an implicit predictive dimension of our knowledge claims consistent with their fallibility: when we properly claim to know something, we do not imply impossibility of being mistaken, but rather hold that we are not wrong and that no sudden twist of future events will show us to be wrong.Filozofski skepticizam dovodi u pitanje naše svakodnevne tvrdnje da nešto znamo ističući da nismo u stanju isključiti mogućnosti pogreške sadržane u dobro poznatim skeptičkim alternativama . Da bih objasnio kako se možemo oduprijeti tome skeptičkom izazovu, najprije uspoređujem filozofsku i svakodnevnu sumnju. Ukazujem na to da se one ne razlikuju s obzirom na način na koji nastoje potkopati tvrdnje da nešto znamo, nego u obilježjima alternativa na koje se pozivaju. U svakodnevnim kontekstima filozofsko-skeptičke alternative ne bi ni trebalo smatrati relevantnima, budući da su sasvim uopćene i nisu poduprte nikakvom naznakom da bi u danim okolnostima uistinu mogle biti aktualizirane. Budući da se ta činjenica ne tiče istinitosti, nego tvrdljivosti naših spoznajnih tvrdnji, pokazujem da dok je naša evidencijska osnova za njihovu tvrdljivost internalistička, njihova istinitost ovisi o određenim pretpostavkama koje se tiču uzročne povijesti naših vjerovanja, pouzdanosti naših spoznajnih sposobnosti, uspjeha u identificiranju i isključivanju relevantnih alternativa itd. U svakodnevnim pripisivanjima znanja te pretpostavke funkcioniraju kao eksternalistički preduvjeti, tako da nešto možemo znati samo ako su one točne a da pritom čak i ne moramo znati jesu li točne. Naposljetku, ističem implicitnu prediktivnu dimenziju naših spoznajnih tvrdnji koja je konsistentna s njihovom pogrešivošću: kada s pravom tvrdimo da nešto znamo, tada ne impliciramo nemogućnost da smo pogriješili, nego smatramo da nismo u krivu i da nikakvi neočekivani budući događaji neće pokazati da smo u krivu.

Public support for social policies or movements is often determined by intuitive considerations, perceived as matters of common sense. Existing theories interpret these dispositions in one of two ways: either as genetic traits inherited from hominid ancestors, or as reified elements of cultural practices. Both of these approaches imply that common sense is local and context-dependent, without any primordial components. Nevertheless, rationality cannot emerge in material environments without a set of necessary beliefs. This means that common sense incorporates universal elements (...) as well. By treating shared factual knowledge as subjective and the basic intuitions as objective, it is possible to understand the roots of cultural paradigms and the parameters that lead to their change over time. The interplay between belief and knowledge determines the type of principles that have the strongest appeal in any society. This process works at the level of the individual, especially in the early formative years, and shapes the generational transfer of values. Of special interest is the possibility of cultural change induced by advancements in science. For example, the social relevance of scientific rationality depends on the perceived compatibility between the necessary intuitions and the supported interpretations of physical phenomena. Global effects are possible in the long run, given the universality of relevant categories. Even the modern trend towards cultural fundamentalism can be reversed, assuming favorable conditions. The goal of this dissertation is to provide a foundation for future research on the evolution of common sense. It is designed as an argument in three main steps. The first part aims to deduce the types of internal and external observables that determine the emergence of rational self-consciousness. The second part derives a limited list of physical properties that can be used to validate the ontological status of rationality. Those properties are shown to be compatible with existing empirical observations in the third part. These conclusions suggest that the progress of democracy can be influenced by future scientific developments, especially through changes in the qualitative approaches to fundamental physical interactions.

Dogmatists often exploit the skeptical argument based on the brains-in-a-vat scenario as a test case for their epistemological enterprises. I argue that this ‘argument’ does not deserve our attention, so it should not be used as a test case. I first show that the possibilities of empirical knowledge and of skeptical scenarios are inconsistent. If so, the BIV-skeptic must make the case for preferring such scenarios over the possibility of empirical knowledge. The central argument of my paper is that the (...) BIV-skeptic can neither rely on any selection principle for this purpose, nor can she claim that she needs no such principle. Then I will show that we can even dispense with the Inconsistency Thesis: if the skeptic wishes, she may allow for the possibility of empirical knowledge. The essay concludes with considering the morals of the above argument for the dogmatist endeavor. (shrink)

The raison d’être of this article is that many a spry-eyed analyst of the works in intelligent computing and robotics fail to see the essential concerning applications development, that of expressing their ultimate goal. Alternatively, they fail to state it suitably for the lesser-informed public eye. The author does not claim to be able to remedy this. Instead, the visionary investigation offered couples learning and computing with other related fields as part of a larger spectre to fully simulate people in (...) their embodied image. For the first time, the social roles attributed to the technical objects produced are questioned, and so with a humorous illustration. (shrink)

El objetivo de este artículo es proporcionar elementos para una comprensión apropiada de las diversas dialécticas entre escepticismo y antiescepticismo en epistemología. En particular, demostrar que cierta tesis escéptica es falsa o que es imposible defenderla coherentemente puede resultar insuficiente para solucionar el problema conceptual derivado de un determinado argumento escéptico a favor de dicha tesis. Incluyo una discusión sobre la fuerza y los límites de los argumentos trascendentales, así como un análisis de su estructura, ilustrado por el argumento de (...)

The aim of this paper is to discuss a basic assumption tacitly shared by many philosophers of mind and language: that whatever can be meant, can be said. It specifically targets John Searle’s account of this idea, focussing on his Principle of Expressibility (PE henceforth). In the first part of the paper, PE is exposed underlining its analyticity (1) and its relevance for the philosophy of language (2), mind (3), society and action (4). In the critical part, the notion of (...) Background is taken into account in order to re-evaluate two basic distinctions: the one between sentence and utterance meanings (5), and the one between native and type speakers (6). PE is reconsidered in the light of the previous arguments as a methodological strategy that does not prevent uses of language from eventual semantic excesses and deficits (7), and a complementary Principle of Expression Fallibility is finally proposed (8).
