Our behavior doesn't always match the beliefs attributed to us, and sometimes the mismatch raises questions about what our beliefs actually are. I compare two approaches to such cases, and argue in favor of the one which allows some belief-attributions to lack a determinate truth-value. That approach avoids an inappropriate assumption about cognitive activity: namely, that whenever we fail in performing one cognitive activity, there is a distinct cognitive activity at which we succeed. The indeterminacy-allowing approach also meshes well with (...) an attractive view of folk-psychology: that ascriptions can help shape the attitudes they report. (shrink)

A philosopher argues that state-sponsored cyberattacks against central military or civilian targets are always acts of war. What is this philosopher doing? According to conceptual analysts, the philosopher is making a claim about our concept of war. According to philosophical realists, the philosopher is making a claim about war per se. In a quickly developing literature, a third option is being explored: the philosopher is engineering the concept of war. On this view, the philosopher is making a proposal about which (...) concept we should have – even if it deviates from the extant concept, and even if it does not capture ‘what war really is’. The activity or method of proposing such revisionary definitions, as well as the metaphilosophical reflection on it, has become known as conceptual engineering. (shrink)

Bortolotti argues that the irrationality of many delusions is no different in kind from the irrationality that marks many non-pathological states typically treated as beliefs. She takes this to secure the doxastic status of those delusions. Bortolotti’s approach has many benefits. For example, it accounts for the fact that we can often make some sense of what deluded subjects are up to, and helps explain why some deluded subjects are helped by cognitive behavioral therapy. But there is an alternative approach (...) that secures the same benefits as Bortolotti’s account while bringing additional benefits. The alternative approach treats both many delusions and many of the non-pathological states to which Bortolotti compares them as in-between states. Subjects in in-between states don’t fully believe the beliefs which it is sometimes convenient to ascribe to them. This alternative approach to belief and belief-ascription fits well with an independently attractive account of the varied purposes of our ordinary attitude ascriptions. It also makes it easier to make fine-grained distinctions between intentional attitudes of different kinds. (shrink)

According to virtue epistemology, the main aim of education is the development of the cognitive character of students (Pritchard, 2014, 2016). Given the proliferation of technological tools such as ChatGPT and other LLMs for solving cognitive tasks, how should educational practices incorporate the use of such tools without undermining the cognitive character of students? Pritchard (2014, 2016) argues that it is possible to properly solve this ‘technology-education tension’ (TET) by combining the virtue epistemology framework with the theory of extended cognition (...) (EXT) (Clark and Chalmers, 1998). He argues that EXT enables us to consider tools as constitutive parts of the students’ cognitive system, thus preserving their cognitive character from technologically induced cognitive diminishment. The first aim of this paper is to show that this solution is not sufficient to solve the TET. Second, I aim to offer a complementary and more encompassing framework of tool-use to address the TET. Then, I apply it to the educational uses of ChatGPT as the most notable example of LLM, although my arguments can be extended to other generative AI systems. To do so, in Sect. 1.1, I present Pritchard’s framework of cognitive character and virtue epistemology applied in education, to which I am committed in this treatment. In Sects. 2 and 3, I respectively illustrate Pritchard’s (2014) solution to the TET, and I highlight the general limitations of his proposal. Thus, in Sect. 4.1 I characterize ChatGPT as a computational cognitive artifact using Fasoli’s (2017, 2018) taxonomy of cognitive artifacts. In Sect. 4.2, I introduce my proposal, which combines Pritchard’s account of virtue epistemology with Fasoli’s (2017, 2018) taxonomy of cognitive artifacts to address the TET. Finally, in Sect. 5.1, I present some epistemically virtuous uses of ChatGPT in educational contexts. To conclude, I argue in favor of a multidisciplinary approach for analyzing educational activities involving AI technologies such as ChatGPT. (shrink)

The imperviousness of delusions to counter-evidence makes it tempting to classify them as imaginings. Bayne and Pacherie argue that adopting a dispositional account of belief can secure the doxastic status of delusions. But dispositionalism can only secure genuinely doxastic status for mental states by giving folk-psychological norms a significant role in the individuation of attitudes. When such norms individuate belief, deluded subjects will not count as believing their delusions. In general, dispositionalism won't confer genuinely doxastic status more often than do (...) competing accounts of belief. (shrink)

Some theories of language, thought, and experience require their adherents to say unpalatable things about human individuals whose capacities for rational activity are seriously diminished. Donald Davidson, for example, takes the interdependence of the concepts of thought and language to entail that thoughts may only be attributed to an individual who is an interpreter of others’ speech. And John McDowell's account of human experience as the involuntary exercise of conceptual capacities can be applied easily only to individuals who make some (...) reasonable judgments, because conceptual capacities are paradigmatically exercised in judgments. In both cases, we seem forced towards an error theory about any ordinary understanding of impaired human individuals as minded, or as undergoing human experience. (shrink)

Draft of forthcoming article in the Journal of Medical Ethics where I discuss ethical tension between LGBT testimony and testimonial trust of medical professionals.

This paper provides a reinterpretation of some of the most influential skeptical arguments, Agrippa’s trilemma, meta-regress arguments, and Cartesian external world skepticism. These skeptical arguments are reasonably regarded as unsound arguments about the extent of our knowledge. However, reinterpretations of these arguments tell us something significant about the preconditions and limits of persuasive argumentation. These results contribute to the ongoing debates about the nature and resolvability of deep disagreement. The variety of skeptical arguments shows that we must distinguish different types (...) of deep disagreement. Moreover, the reinterpretation of skeptical arguments elucidates that deep disagreement cannot be resolved via argumentation. (shrink)

We can increase our understanding of expression by considering an analogy to demonstrative reference. The connections between a demonstrative phrase and its referent, in a case of fully successful communication with that phrase, are analogous to the connections between an expressible state and the behavior that expresses it. The connections in each case serve to maintain a certain status for the connected elements: as actions of persons; or as objects, events, or states significant to persons. The analogy to demonstrative reference (...) helps show that a positive account of expression can make conceptual connections between expressed states and expressive behaviors without courting reductive behaviorism. A general account of expression as marked by these connections is compared to accounts of expression offered by Dorit Bar-On and Mitchell Green. Bar-On’s account turns out to be compatible with the account proposed here, once some of its consequences are fully appreciated. Green’s account rules out, as not expressive, some behaviors like crouching (in fear) that intuitively seem expressive. When Green’s account is altered to allow such behaviors back in, the resulting account also fits the one proposed. (shrink)

Discrimination is a central epistemic capacity but typically, theories of discrimination only use discrimination as a vehicle for analyzing knowledge. This paper aims at developing a self-contained theory of discrimination. Internalist theories of discrimination fail since there is no compelling correlation between discriminatory capacities and experiences. Moreover, statistical reliabilist theories are also flawed. Only a modal theory of discrimination is promising. Versions of sensitivity and adherence that take particular alternatives into account provide necessary and sufficient conditions on discrimination. Safety in (...) contrast is not sufficient for discrimination as there are cases of safety that are clearly instances of discrimination failure. The developed account of discrimination between objects will be extended to discrimination between kinds and between types. (shrink)

Dorit Bar-On aims to account for the distinctive security of avowals by appealing to expression. She officially commits herself only to a negative characterization of expression, contending that expressive behavior is not epistemically based in self-judgments. I argue that her account of avowals, if it relies exclusively on this negative account of expression, can't achieve the explanatory depth she claims for it. Bar-On does explore the possibility that expression is a kind of perception-enabling showing. If she endorsed this positive account, (...) her argument would re-gain an explanatory advantage over its rivals. But extending this account to linguistic expressive behavior would bring Bar-On very close to constitutive accounts of first-person authority. (shrink)

This book is primarily about checking and only derivatively about knowing. Checking is a very common concept for describing a subject’s epistemic goals and actions. Surprisingly, there has been no philosophical attention paid to the notion of checking. In Part I, I develop a sensitivity account of checking. To be more explicit, I analyze the internalist and externalist components of the epistemic action of checking which include the intentions of the checking subject and the necessary externalist features of the method (...) used. Crucially, successfully checking whether p is true requires using a method that is sensitive with respect to p, i.e. a method that would not indicate that p, if p were false. In Part II, I use the distinction between knowing and checking to explain central puzzles about knowledge, particularly puzzles centering on knowledge closure, puzzles concerning bootstrapping and the skeptical puzzle. Moreover, the book clarifies a dispute about modal epistemology, concerning the application of the sensitivity principle. By arguing that sensitivity is necessary for checking but not knowing, I explain where our persisting intuitions about sensitivity have their place in epistemology. (shrink)

Keith DeRose’s solution to the skeptical problem is based on his indirect sensitivity account. Sensitivity is not a necessary condition for any kind of knowledge, as direct sensitivity accounts claim, but the insensitivity of our beliefs that the skeptical hypotheses are false explains why we tend to judge that we do not know them. The orthodox objection line against any kind of sensitivity account of knowledge is to present instances of insensitive beliefs that we still judge to constitute knowledge. This (...) objection line offers counter-examples against the claim of direct sensitivity accounts that sensitivity is necessary for any kind of knowledge. These examples raise an easy problem for indirect sensitivity accounts that claim that there is only a tendency to judge that insensitive beliefs do not constitute knowledge, which still applies to our beliefs that the skeptical hypotheses are false. However, a careful analysis reveals that some of our beliefs that the skeptical hypotheses are false are sensitive; nevertheless, we still judge that we do not know them. Therefore, the fact that some of our beliefs that the skeptical hypotheses are false are insensitive cannot explain why we tend to judge that we do not know them. Hence, indirect sensitivity accounts cannot fulfill their purpose of explaining our intuitions about skepticism. This is the hard problem for indirect sensitivity accounts. (shrink)

This paper provides a thorough analysis of two often informally stated claims. First, successful argumentation in the sense of persuasive argumentation requires agreement between the interlocutors about the rationality of arguments. Second, a general agreement about rationality of arguments cannot itself be established via argumentation, since such an attempt leads to an infinite meta‐regress. Hence, agreement about the rationality of arguments is a precondition for successful argumentation. As the paper argues, these plausible claims hold under the assumption that interlocutors are (...) subjectively rational and follow their own standards of rationality when engaging in argumentation.

The proof paradox results from conflicting intuitions concerning different types of fallible evidence in a court of law. We accept fallible individual evidence but reject fallible statistical evidence even when the conditional probability that the defendant is guilty given the evidence is the same, a seeming inconsistency. This paper defends a solution to the proof paradox, building on a sensitivity account of checking and settling a question. The proposed sensitivity account of legal proof not only requires sensitivity simpliciter but sensitivity (...) of each relevant step of the proof procedure and/or sensitivity concerning all relevant alternatives. This account avoids problems that have been identified for other sensitivity views of legal proof. Moreover, it is argued that sensitivity, rather than safety, is the crucial modal condition for legal proof. It is, finally, shown that the provided account can fruitfully support very different existing views on the relationship between knowledge and legal proof. (shrink)

Questions surrounding deep disagreement have gained significant attention in recent years. One of the central debates is metaphysical, focusing on the features that make a disagreement deep. Proposals for what makes disagreements deep include theories about hinge propositions and first epistemic principles. In this paper, I criticize this metaphysical discussion by arguing that it is methodologically flawed. Deep disagreement is a technical or semi-technical term, but the metaphysical discussion mistakenly treats it as a common-sense concept to be analyzed and captured (...) by our pre-theoretical intuitions. Since the literature on deep disagreement is subject to this fundamental confusion and deep disagreement is not a helpful umbrella term either, I propose eliminating the notion of deep disagreement from the philosophical discourse. Instead of analyzing the nature of deep disagreement, we should develop theories about different forms of disagreement, including disagreement about hinge propositions and disagreement about epistemic principles, and, in particular, a theory of rationally irresolvable disagreement. (shrink)

The discussion about deep disagreement has gained significant momentum in the last several years. This discussion often relies on the intuition that deep disagreement is, in some sense, rationally irresolvable. In this paper, I will provide a theory of rationally irresolvable disagreement. Such a theory is interesting in its own right, since it conflicts with the view that rational attitudes and procedures are paradigmatic tools for resolving disagreement. Moreover, I will suggest replacing discussions about deep disagreement with an analysis of (...) rationally irresolvable disagreement, since this notion can be more clearly defined than deep disagreement and captures the basic intuitions underlying deep disagreement. I will first motivate this project by critically assessing the current debate about deep disagreement. I then detail the notions of rationality and resolvable disagreement which are crucial for a suitable theory of rationally irresolvable disagreement before sketching various instances of rationally irresolvable disagreement. Finally, I argue for replacing theories of deep disagreement with theories of rationally irresolvable disagreement, an approach that has significant advantages over existing theories of deep disagreement which focus on hinge propositions or fundamental epistemic principles.

Berry, Daniels, and Ladin make a strong argument for discontinuing the use of, “lack of social support,” as an organ transplantation listing criterion. This argument, however, actually leads to conclusions much stronger than those that the authors’ propose: The argument works equally well against using, (1) any “psychosocial” factors at all as a listing criterion, and, (2) any criteria other than factors that directly relate to empirically established medical need, and/or empirically established survival rate. Moreover, while the authors rightly point (...) to a lack of empirical evidence connecting social support to survivability, they neglect mentioning that the empirical literature on social support provides grounds to favor listing persons who seem to, sadly, lack a social support system.

Modal knowledge accounts that are based on standards possible-worlds semantics face well-known problems when it comes to knowledge of necessities. Beliefs in necessities are trivially sensitive and safe and, therefore, trivially constitute knowledge according to these accounts. In this paper, I will first argue that existing solutions to this necessity problem, which accept standard possible-worlds semantics, are unsatisfactory. In order to solve the necessity problem, I will utilize an unorthodox account of counterfactuals, as proposed by Nolan, on which we also (...) consider impossible worlds. Nolan’s account for counterpossibles delivers the intuitively correct result for sensitivity i.e. S’s belief is sensitive in intuitive cases of knowledge of necessities and insensitive in intuitive cases of knowledge failure. However, we acquire the same plausible result for safety only if we reject his strangeness of impossibility condition and accept the modal closeness of impossible worlds. In this case, the necessity problem can be analogously solved for sensitivity and safety. For some, such non-moderate accounts might come at too high a cost. In this respect, sensitivity is better off than safety when it comes to knowing necessities. (shrink)

That bootstrapping and Moorean reasoning fail to instantiate persuasive argumentation is an often informally presented but not systematically developed view. In this paper, I will argue that this unpersuasiveness is not determined by principles of justification transmission but by two straightforward principles of rationality, understood as a concept of internal coherence. First, it is rational for S to believe the conclusion of an argument because of the argument, only if S believes sufficiently many premises of the argument. Second, if S (...) doubts that a source _O_ is reliable and believes that information _i_ is delivered by _O_, then S rationally suspends judgment about the truth of _i_. This paper aims to accomplish two tasks. First, it provides a thorough analysis of why bootstrapping argumentation is not an instance of rational persuasion. Second, it contains a more general theory about preconditions and limits of persuasive argumentation. (shrink)

Given the explanatory stalemate between ‘embedded’ (EMB) and ‘extended’ (EXT) cognition, various authors have proposed normative and moral arguments in favour of EXT. According to what we call the “extended cognition moral narrative” (EXT-MN) (Cassinadri, 2022), we should embrace EXT and dismiss EMB, because the former leads to morally preferable consequences with respect to the latter. In this article we argue that two arguments following the EXT moral narrative are flawed. In Sect. 2.1 and 2.2, we present respectively King (2016) (...) and Vold’s (2018) ‘argument from assessment of capacities’ (AAC) and Clowes (2013), Farina and Lavazza’s (2022a) ‘cognitive diminishment argument’ (CDA). The AAC states that we should embrace EXT over EMB since the former is better at attributing cognitive credit to individuals with learning disabilities who use assistive tools to complete their learning tasks, thus avoiding their marginalisation. The CDA states that EMB implies a morally undesirable picture of the agent in terms of cognitive diminishment. In Sect. 3, we clarify and criticise the underlying assumptions of the AAC and CDA: the “cognitive credit assumption”, the “marginalisation assumption” and, more generally, an ableist conception of disabled agency. In Sect. 3.1, we discuss the role of moto-perceptual skills and metacognitive credit involved in complex cases of tool-use, to demonstrate that the EXT-MN is uninformative in addressing these cases. To conclude, in Sect. 4 we argue that AAC and CDA fail to present EXT as descriptively and normatively superior to EMB. (shrink)

In this paper, I aim to demonstrate that the consequences of the current United States health insurance scheme on both physician and patient autonomy is dire. So dire, in fact, that the only moral solution is something other than what we have now. The United States healthcare system faces much criticism at present. But my focus is particular: I am interested in the ways in which insurance interferes with physician and patient autonomy. I will argue in favor of an expansion (...) of the traditional conception of what I call “medical autonomy” or “healthcare autonomy” and the usual role it plays in bioethical discussions. More generally, I show that in morally designing or evaluating any healthcare system, serious attention should be paid to how this system helps foster what I call active autonomy. (shrink)

Populism has become a buzzword within the political arena of the twenty-first century. It is near omnipresent in our discourse, most of the time without being tied to any particularly defined conceptualization. This proliferation of populist and meta-populist discourse results in the meaning of the term populism becoming taken for granted without ever resulting in its user’s need to feel it necessary to expand on its actual meaning. The aim of this paper is to try to shed some light on (...) the definition of the word populism and its usage. I adopt and apply some tools proposed by Wittgenstein’s Philosophical Investigations, namely his idea of family resemblance and meaning as use. Firstly, I will consider populism as a family resemblance term. Instead of trying to entangled populism within a framework of fixed and essential features, populism should be seen as contingent and contextual intertwining of different characteristics which make us immediately recognize a phenomenon as populism. Secondly, I will propose three different uses of populism within academic literature – populism as a classifier, as an admonition and as a descriptor - in order to show how the meaning that we attributed to the term might change according to the usage we make of it. Consequently, each theory of populism advanced should be conceived in light of the scope of the analysis and the specific use we make of the word within political debate. This approach would allow us to maintain the word populism in spite of its lack of a central definition, while allowing a plurality of overlapping and conflictual meanings. (shrink)

The orthodox view about sensitivity and induction has it that beliefs formed via induction are insensitive. Since inductive knowledge is highly plausible, this problem is usually regarded as a reductio argument against sensitivity accounts of knowledge. Some adherents of sensitivity defend sensitivity against this objection, for example by considering backtracking interpretations of counterfactuals. All these extant views about sensitivity and induction have to be revised, since the problem of sensitivity and induction is a different one. Regardless of whether we allow (...) backtracking interpretations of counterfactuals, some instances of induction yield insensitive beliefs whereas others yield sensitive ones. These results are too heterogenous for providing a plausible sensitivity-account of inductive knowledge. Induction remains a serious problem for sensitivity accounts of knowledge. (shrink)

Offering a solution to the skeptical puzzle is a central aim of Nozick's sensitivity account of knowledge. It is well-known that this account faces serious problems. However, because of its simplicity and its explanatory power, the sensitivity principle has remained attractive and has been subject to numerous modifications, leading to a of sensitivity accounts. I will object to these accounts, arguing that sensitivity accounts of knowledge face two problems. First, they deliver a far too heterogeneous picture of higher-level beliefs about (...) the truth or falsity of one's own beliefs. Second, this problem carries over to bootstrapping and Moorean reasoning. Some beliefs formed via bootstrapping or Moorean reasoning are insensitive, but some closely related beliefs in even stronger propositions are sensitive. These heterogeneous results regarding sensitivity do not fit with our intuitions about bootstrapping and Moorean reasoning. Thus, neither Nozick's sensitivity account of knowledge nor any of its modified versions can provide the basis for an argument that bootstrapping and Moorean reasoning are flawed or for an explanation why they seem to be flawed.

In epistemology, the concept of knowledge is of distinctive interest. This fact is also reflected in the discussion of epistemic value, which focuses to a large extend on the value problem of knowledge. This discussion suggests that knowledge has an outstanding value among epistemic standings because its value exceeds the value of its constitutive parts. I will argue that the value of knowledge is not outstanding by presenting epistemic standings of checking, transferring knowledge, and proving in court, whose values exceed (...) the value of knowledge in certain contexts. Moreover, the values of these other epistemic standings do not always rely on the value of knowledge. In terms of value, knowledge is not an outstanding epistemic concept. Hence, in terms of value we cannot find support for the privileged position that knowledge enjoys in epistemology. (shrink)

This paper studies proof systems for the logics of super-strict implication ST2–ST5, which correspond to C.I. Lewis’ systems S2–S5 freed of paradoxes of strict implication. First, Hilbert-style axiomatic systems are introduced and shown to be sound and complete by simulating STn in Sn and backsimulating Sn in STn, respectively(for n=2,...,5). Next, G3-style labelled sequent calculi are investigated. It is shown that these calculi have the good structural properties that are distinctive of G3-style calculi, that they are sound and complete, and (...) it is shown that the proof search for G3. ST2 is terminating and therefore the logic is decidable. (shrink)

What is a race? Ernst Mayr (1904–2005) distinguishes between species in which biological change is continuous in space, and species in which groups of populations with different character combinations are separated by borders. In the latter species, the entities separated by borders are geographic races or subspecies. Many anthropology textbooks describe human races as discrete (or nearly discrete) clusters of individuals, geographically localized, each of which shares a set of ancestors, and hence can be distinguished from other races by their (...) common gene pool or by different alleles fixed in each.

In this paper I focus on a passage of Plato’s Laws that so far has been the object of little study (V 731d-732b). In the Laws, the origin of all evil is neither an ontological principle, as in the Judaeo-Christian tradition, nor a simple lack of knowledge (àghnoia) or a lack of knowledge combined with the false presumption of knowledge (amathìa). Rather, in this passage amathìa itself is traced back to “excessive self-love” (sphòdra heautoû philìa). I show that this “excess” (...) has a specific “anthropological” relevance, because it is not limited to the intellectual sphere or to the will, but directly concerns the human way of loving. The thesis that I argue for in this paper is that this “excess” is a possibility implicit in the human being qua àplestos, and should therefore be interpreted in an “anthropological” sense: it does not indicate a simple “lack” of balance, but rather a possibility and a risk to which humans expose themselves when they exceed the homeostatic balance of needs typical of non-human animals. Finally, I trace the various steps of this “anthropology of excess” back to its origin: the image of the leaky jar found in the Gorgias. (shrink)

Botticelli and Tizian depict the Annunciation in two very different ways. Botticelli portrays a kneeling angel in an act of guiding from below, while Tizian represents an angel imposing himself from above with an authoritarian forefinger. Botticelli's painting suggests an intention of orientation that is not authoritarian yet able to bring about a transformation (Umbildung). It also suggests that an individual's transformation cannot be achieved in a closed solipsistic dimension, but requires a disclosure from otherness. My theory is that at (...) the origin of ethics there is a non-authoritarian way of orientation that comes from otherness and arises from the emotional sphere thanks to a "care of desire". The expression cura sui has often been interpreted as a care confined to a private and solipsistic dimension with the aim of strengthening the self-referential subject. By "care of desire" I mean a care not turned upon itself but made possible by a disclosure coming from otherness and addressed to the transformation of the individual and of society. In the human existence, emotions reveal an extraordinary plasticity. They are not already regulated by instinct but develop and get to maturity even many years after biological birth. Moreover, this maturation process does not follow a universal process identical for everyone, being different for every individual. In fact it finds its realization in the unique order of feelings (ordo amoris) that characterizes every individual. Emotions guide actions and the way we interact with the others and with the world. In the human existence they become plastic and don't have only a homeostatic function of self-regulation. They give flexibility to our way of perceiving, of existing and of taking our position in the world. The care of desire is dedicated to the plasticity of emotions and makes ethics, i.e. a person's formation process (Bildung) and flourishing, possible. It also allows the transition from the “environmental closedness” (Umweltgeschlossenheit) to the world-openness (Weltoffenheit). To sum up, the care of desire implies the transition from a solipsistic self-care to a “care for world-openness”. From this point of view, emotion is no more the secondary result of a cognitive process, but at the origin of every formative, perceptive and cognitive process: In the beginning was the emotion. Yet in this process of creative transformation not every emotion has the same significance: at the core of emotions’ plasticity there are love and wonder (thaumàzein), whose peculiar feature is “lack of envy” (aphthonoi).

Epistemologists understand radical skepticism as arising from two principles: Closure and Underdetermination. Both possess intuitive prima facie support for their endorsement. Understanding how they engender skepticism is crucial for any reasonable anti-skeptical attempt. The contemporary discussion has focused on elucidating the relationship between them to ascertain whether they establish distinct skeptical questions and which of the two constitutes the ultimately fundamental threat. Major contributions to this debate are due to Brueckner, Cohen, and Pritchard. This contribution aims at defending Brueckner’s contention (...) that underdetermination expresses the fundamental skeptical threat and that the closure-based argument can ultimately be reduced to it, at least concerning skeptical contexts. This will be achieved by undermining Cohen’s objections to Brueckner on both counts. Cohen’s argument endorses a picture of evidential underdetermination, which, while apt for non-skeptical contexts, cannot be applied to radical skepticism. A comparison with a case of scientific underdetermination is developed to argue for this idea. Our argument is then applied to the principle equivalence issue and to objections against it. It is then shown how this analysis possesses a distinctive effect on our understanding of the skeptical threat and the assessment of successful anti-skeptical strategies. (shrink)

Intervista a Guido del Giudice sulla "Bruno Renaissance".

This article aims to provide a structural analysis of the problems related to the easy knowledge problem. The easy knowledge problem is well known. If we accept that we can have basic knowledge via a source without having any prior knowledge about the reliability or accuracy of this source, then we can acquire knowledge about the reliability or accuracy of this source too easily via information delivered by the source. Rejecting any kind of basic knowledge, however, leads into an infinite (...) regress and, plausibly, to skepticism. The article argues that the third alternative, accepting basic knowledge but rejecting easy knowledge, entails closure failure. This is obviously the case for deductive bootstrapping, but, notably, the problem also arises for inductive bootstrapping. Hence, the set of problems related to the easy knowledge problem has the structure of a trilemma. We are forced to accept easy knowledge, closure failure, or skepticism. (shrink)

Time as the key to a theory of everything became recently a renewed topic in scientific literature. Social constructivism applied to physics abandons the inevitable essentials of nature. It adopts uncertainty in the scope of the existential activity of scientific research. We have enlightened the deep role of social constructivism of the predetermined Newtonian time and space notions in natural sciences. Despite its incompatibility with determinism governing the Newtonian mechanics, randomness and entropy are inevitable when negative localized energy is transformed (...) into spatially dissipative heat. In sharp contrast to the Newtonian notion, social constructivism makes room for the temporal twin of cyclic conservation and pseudo-linearly structural evolution both reconciling mechanical order and thermodynamic chaos in Leibnizian space-time. In the broad scope of natural sciences this triad nature of time produces a multiple reality and gives appropriate answers on virtual physical paradoxes. (shrink)

INTERVENTO DI GUIDO DEL GIUDICE NEL CORSO DELLA TAVOLA ROTONDA: "GIORDANO BRUNO E LA CULTURA ROSACROCIANA IN ITALIA E IN EUROPA" PERUGIA, 12 MARZO 2011.

Vogel argues that sensitivity accounts of knowledge are implausible because they entail that we cannot have any higher-level knowledge that our beliefs are true, not false. Becker and Salerno object that Vogel is mistaken because he does not formalize higher-level beliefs adequately. They claim that if formalized correctly, higher-level beliefs are sensitive, and can therefore constitute knowledge. However, these accounts do not consider the belief-forming method as sensitivity accounts require. If we take bootstrapping as the belief-forming method, as the discussed (...) cases suggest, then we face a generality problem. Our higher-level beliefs as formalized by Becker and Salerno turn out to be sensitive according to a wide reading of bootstrapping, but insensitive according to a narrow reading. This particular generality problem does not arise for the alternative accounts of process reliabilism and basis-relative safety. Hence, sensitivity accounts not only deliver opposite results given different formalizations of higher-level beliefs, but also for the same formalization, depending on how we interpret bootstrapping. Therefore, sensitivity accounts do not fail because they make higher-level knowledge impossible, as Vogel argues, and they do not succeed in allowing higher-level knowledge, as Becker and Salerno suggest. Rather, their problem is that they deliver far too heterogeneous results. (shrink)

Scheler, like Jaspers, gives a key importance to the relations with alterity and grounds both the individual formation and social ontology on the practices of “sharing emotions”. My work attempts to interpret the impairments related to the capacities of communication – that Jaspers places at the roots of psychopathology and that the Japanese psychiatrist Bin Kimura has more recently argued to be the core of schizophrenia – as impairment of what Scheler calls ordo amoris, that is the “order of feeling” (...) of a person: like a "Psychopathology of the Ordo Amoris".

The aim of this paper is to analyse and develop how scepticism becomes an intelligible question starting from requirements that epistemologists themselves aim to endorse. We argue for and defend the idea that the root of scepticism is the underdetermination principle by articulating its specificitya respectable epistemic principle and by defending it against objections in current literature. This engagement offers a novel understanding of underdetermination-based scepticism. While most anti-sceptical approaches challenge scepticism by understanding it as postulating uneliminated scenarios of mass (...) deception, or as endorsing unnatural epistemic requirements, we argue here that both contentions are mistaken. Underdetermination-based scepticism targets our beliefs by issuing a genuine question about the rational support they enjoy. If we cannot establish that the sources of our beliefs provide them the required epistemic merit and authority, they lack non-arbitrary grounds. This has a sizable impact on what constitutes a satisfactory anti-sceptical strategy. Strategies that merely focus on the scenario-based aspect of scepticism, or on the truth-functional evaluation of our beliefs, are shown to miss the mark of the sceptical threat. The proposed analysis ultimately provides a shift in perspective concerning the character and reach of philosophical doubt. (shrink)

A NEW, ORIGINAL GIORDANO BRUNO'S AUTOGRAPH, IN THE PRAGUE'S COPY OF CAMOERACENSIS ACROTISMUS. Extract from "The dispute of Cambrai. Camoeracensis Acrotismus" edited by Guido del Giudice, publ. Di Renzo, Rome 2008.

There have been innumerable attempts to characterize personal identity either in terms of psychological continuity or in terms of the linear and self-referential process of reproduction of one's self. I will defend the thesis according to which personal identity emerges mainly as a process of transcendence of one's own "minimal self". It is precisely by means of this critical distancing from his self, I contend, that the individual learns to see himself under a new perspective as far as to experience (...) his self as a surprise. Amazed at his own self, he lives a reawakening which leads him to a transformation of his way of living. This transcendence of the self cannot take place self-referentially but only through the force of an example provided by another person. Such act neither aims at the annihilation of the individual, nor does it contrast with self-love. It is in conlict merely with what Harry Frankfurt calls "selfindulgence". The idea of a transcendence of the self is already to be found in Plato, who fostered the overcoming of and puriication from amathia (in the sense of a "not knowing but pretending to know") and from an excessive love of oneself. Indeed, these latter would be the two grave diseases which render formless the soul of a human being, for they stand in the way of the cura sui. The same theme will reappear in Max Scheler's phenomenological reduction, which endeavours to bracket egocentrism (construed as excessive love of oneself) in order to give a form to the personal identity.

I will compare Lehrer’s anti-skeptical strategy from a coherentist point of view with the anti-skeptical strategy of the Mooreans. I will argue that there are strong similarities between them: neither can present a persuasive argument to the skeptic and both face the problem of easy knowledge in one way or another. However, both can offer a complete and self-explanatory explanation of knowledge although Mooreanism can offer the more natural one. Hence, one has good reasons to prefer Mooreanism to Lehrer’s anti-skeptical (...) approach, if one does not prefer coherentism to foundationalism for other reasons. (shrink)
