We reconsider the pragmatic interpretation of intuitionistic logic [21] regarded as a logic of assertions and their justi cations and its relations with classical logic. We recall an extension of this approach to a logic dealing with assertions and obligations, related by a notion of causal implication [14, 45]. We focus on the extension to co-intuitionistic logic, seen as a logic of hypotheses [8, 9, 13] and on polarized bi-intuitionistic logic as a logic of assertions and conjectures: looking at the (...) S4 modal translation, we give a de nition of a system AHL of bi-intuitionistic logic that correctly represents the duality between intuitionistic and co-intuitionistic logic, correcting a mistake in previous work [7, 10]. A computational interpretation of cointuitionism as a distributed calculus of coroutines is then used to give an operational interpretation of subtraction.Work on linear co-intuitionism is then recalled, a linear calculus of co-intuitionistic coroutines is de ned and a probabilistic interpretation of linear co-intuitionism is given as in [9]. Also we remark that by extending the language of intuitionistic logic we can express the notion of expectation, an assertion that in all situations the truth of p is possible and that in a logic of expectations the law of double negation holds. Similarly, extending co-intuitionistic logic, we can express the notion of conjecture that p, de ned as a hypothesis that in some situation the truth of p is epistemically necessary. (shrink)

The paper begins by reviewing two problems for fallibilism: the lottery problem, or the problem of explaining why fallible evidence, though otherwise excellent, is not enough to know that one will lose the lottery, and Gettier problems. It is then argued that both problems can be resolved if we note an important illocutionary force of knowledge attributions: namely, that when we attribute knowledge to someone we mean to give the person credit for getting things right. Alternatively, to say that a (...) person knows is to say that she got things right due to her own abilities, efforts and actions, rather than due to dumb luck, or blind chance, or something else.

This paper deals with the strategy of defence that Aristotle dedicates to the principle of contradiction; the analysis is concentrated on passages of Metaphysics Gamma 4. The main thesis of the paper is that Aristotle’s strategy is an ontological, and therefore not only a logical, one: the principle is defended on the basis of the, from an ontological point of view, unacceptable consequences which would arise in case of the absence of the principle itself. These consequences are, for instance, the (...) disappearance of properties, of essences, of individual entities and of the plurality of essentially distinguishable entities, since the contents of the properties, the role of properties as essences and the constitution of the individual entities cannot hold, if the principle of contradiction does not hold. The principle of contradiction is, therefore, not only a logical principle: it is the ontological presupposition of the whole reality; without it there is no entity. (shrink)

We defend Uniqueness, the claim that given a body of total evidence, there is a uniquely rational doxastic state that it is rational for one to be in. Epistemic rationality doesn't give you any leeway in forming your beliefs. To this end, we bring in two metaepistemological pictures about the roles played by rational evaluations. Rational evaluative terms serve to guide our practices of deference to the opinions of others, and also to help us formulate contingency plans about what to (...) believe in various situations. We argue that Uniqueness vindicates these two roles for rational evaluations, while Permissivism clashes with them. (shrink)

The essay consists in the analysis of the problem of the evil in the man and in the analysis of the remedies which the man can find against the evil. Plato affirms the presence of an active principle of evil in the soul of every man, which coincides with some instincts of the appetitive soul; the opposite principle to the evil is the reason, which needs, though, a correct education in order to be able to fight efficiently against the evil (...) in us. The man can be seen as a battle field of these opposite forces. Plato describes the presence of the evil in us in some passages of Republic Book 9, where he compares the appetitive part of the soul with a monster. The destiny of every person in her earthly existence consists in the continuing control of the appetitive part of the soul, if the status of ethical education is to be reached and maintained. The man who remains in the realm of the opinion, that is, in the realm of the doxa is an individual who only disposes of unstable opinions and who as a consequence do not have authentic remedies against the appetitive part. On the contrary, the individual who can ascend to the realm of being through the hard education represented by arithmetic, geometry, stereometry, astronomy, harmony and, finally, dialectic is really able to contrast the force of the evil within the individual. Ethics is really possible only through the complete education which passes through these disciplines: the more the individuals is theoretically educated, the more the individual is ethically educated. The knowledge of ideas is the only authentic therapy against the evil in us. (shrink)

This essay is the first part of an analysis on the form and matter in the works of Aristotle. Within the whole analysis, I shall examine passages taken from different works of Aristotle that are relevant to the investigation on form and matter. In this essay, I shall focus exclusively on the chapter Metaphysics Zeta 3. The concepts of substance, matter, ontological subject, form, composite substance, this something and separated, which are consistently used by Aristotle within the development of the (...) mentioned chapter, will be part of my survey of the contents of the chapter. The central argument of Metaphysics Zeta 3, which maintains the equivalence between substance and the feature represented by ontological subject, and which leads, through this first equivalence and through the equivalence between matter and ontological subject, to the result that matter is (the only) substance, will be investigated step by step so that all presuppositions, entailments, and consequences of the argument itself can be clearly shown. The problems which are caused by the mentioned equivalence of substance and ontological subject will be pointed out during my look at the chapter’s contents. In particular, Aristotle cannot accept that, in spite of the ontological subject being a correct feature of substance qua substance, substance is therewith reduced to matter. Being the ontological subject does not represent the only ontological feature of substance qua substance; the ontological features too of substance qua substance that are represented by being a this something and being separated belong to the concept of substance: they can never be forgotten within a right interpretation of substance. The identification of substance only with matter can never be accepted. Only the ontological values of substance represented by the form and by the composite substance possess the ontological features “being a this something” and “being separated”. Therefore, the ontological values of substance as form and as a composite substance must always be reckoned with in a correctly interpreted ontology. Neither of these values can be forgotten within an accurate inquiry of ontology. Hence, regardless of whether matter is substance and is correctly interpreted as substance, the values of substance as form and as composite substance must belong, in Aristotle’s view, to any right ontological system whatsoever. The plurality of values for substance, which I personally advocate, finds confirmation thanks to chapter Metaphysics Zeta 3: Matter, form, and composite substance all represent values for substance, despite the differences which they have as regards their own ontological features.

While epistemologists have long debated what it takes for beliefs to be justified, they've devoted much less collective attention to the question of what it takes for beliefs to be excused, and how excuses differ from justifications. This stands in contrast to the state of affairs in legal scholarship, where the contrast between justifications and excuses is a standard topic in introductory criminal law textbooks. My goal in this paper is to extract some lessons from legal theory for epistemologists seeking (...) to distinguish epistemic justifications from epistemic excuses. First, I'll provide a brief overview of appeals to the justification/excuse distinction in epistemology, focusing on the internalism/externalism debate. Then, I'll identify some choice points in legal theory for how to think about the function of the justification/excuse distinction, and will in turn correspond to analogous choice points in epistemology. Ultimately, I'll argue that depending on which way we go at some crucial junctures, we can motivate either a traditional, non‐factive, internalist conception of justification, or a purely factive one where truth is all that's required for a belief to be justified. But there's no clear path, via legal theory, to view that only beliefs that amount to knowledge are justified. (shrink)

While recent discussions of contextualism have mostly focused on other issues, some influential early statements of the view emphasized the possibility of its providing an alternative to both coherentism and traditional versions of foundationalism. In this essay, I will pick up on this strand of contextualist thought, and argue that contextualist versions of foundationalism promise to solve some problems that their non-contextualist cousins cannot. In particular, I will argue that adopting contextualist versions of foundationalism can let us reconcile Bayesian accounts (...) of belief updating with a version of the holist claim that all beliefs are defeasible.

Almost everyone believes that testimony can transmit knowledge from speaker to hearer. What some philosophers mean by this is ordinary and pedestrian-- they mean only that, in at least some cases, a speaker S knows that p, S testifies that p to a hearer H, and H comes to know that p as a result of believing S's testimony. There is disagreement about how this occurs, but that it does occur is sufficient for the transmission of knowledge in the intended (...) sense. On this understanding of transmission, the natural questions are these: (1) What conditions, in addition to speaker knowledge and speaker testimony, are sufficient for the hearer to gain testimonial knowledge?; and (2) Is speaker knowledge always necessary for testimonial knowledge? That is: Is all testimonial knowledge transmitted knowledge? (shrink)

This paper argues for several related theses. First, the epistemological position that knowledge requires safe belief can be motivated by views in the philosophy of science, according to which good explanations show that their explananda are robust. This motivation goes via the idea—recently defended on both conceptual and empirical grounds—that knowledge attributions play a crucial role in explaining successful action. Second, motivating the safety requirement in this way creates a choice point—depending on how we understand robustness, we'll end up with (...) different conceptions of safety in epistemology. Lastly, and most controversially, there's an attractive choice at this point that will not vindicate some of the most influential applications of the safety-theoretic framework in epistemology, e.g., Williamson's arguments against the KK principle, and luminosity.

The aim of this paper is to investigate Nishida Kitarō’s way of philosophizing in the light of the concept of “transition” in order to deepen our understanding of both Nishida’s philosophy and our thinking about and in transitions, using the concept of “boundary” or “border” (Grenze) as a catalyst. For that purpose, we focus on Nishida’s essay “Place” (「場所」), passing through different parts of the text as if through successive gates on a path of transition between one place and the (...) next, until we reach the final place of “absolute nothingness.” Dwelling on this place, we turn our attention to its internal structure and try to depict it along the outlines of a boundary, following the movements taking place in Nishida’s essay. The second part proposes an interpretation of the place of nothingness as an interminable practice of boundary-crossing that doesn’t come to a halt in a final, all-encompassing place, but dynamically situates itself on countless intersecting planes. After a more or less abstract analysis of the concept of “boundary,” we will apply and concretize this approach by using the example of the skin. To this end, we expose five main features of the skin as boundary: permeability, enclosure, excessiveness, interstitiality and reciprocal self-formation. (shrink)

The study deals with the main aspects of substance in the works of Aristotle. The presence of a plurality of values for substance is the central idea of the study; in particular, substance has 1) the value of living biological entity and 2) the value of form of the biological entity; both values are fundamental components of Aristotle's theory of substance. The prevalence, in the works of Aristotle, of the first or of the second of the two values depends on (...) the prevailing research interest of Aristotle in each work. The idea of a continuity in Aristotle's interpretation of substance in Aristotle's works is endorsed. This research treats, moreover, of the role of form as actuality, of the relations between form and matter in the material entities, and of the problem of the unity of definition. (shrink)

Part One of the paper argues against evidentialism and individualism in religiousepistemology, and in favor of a “social turn” in the field. The idea here is that humanbelief in general, and religious belief in particular, is largely characterized by epistemicdependence on other persons. An adequate epistemology, it is agued, ought to recognizeand account for social epistemic dependence.Part Two considers a problem that becomes salient when we make such a turn. Inshort, how are we to understand the transmission of knowledge and (...) rational faith in areligious tradition? The problem arises because, by all accounts, even the best traditionstransmit superstitions, self-serving prejudices, and other things that are down right falseon any reasonable view. So how is it that these same traditions can also transmit rationalfaith and even knowledge by means of the very same channels, for example channels ofreligious authority and religious teaching?Part Three offers a tentative solution to this problem.

In the paper it is argued that bridging the digital divide may cause a new ethical and social dilemma. Using Hardin's Tragedy of the Commons, we show that an improper opening and enlargement of the digital environment (Infosphere) is likely to produce a Tragedy of the Digital Commons (TDC). In the course of the analysis, we explain why Adar and Huberman's previous use of Hardin's Tragedy to interpret certain recent phenomena in the Infosphere (especially peer-to-peer communication) may not be entirely (...) satisfactory. We then seek to provide an improved version of the TDC that avoids the possible shortcomings of their model. Next, we analyse some problems encountered by the application of classical ethics in the resolution of the TDC. In the conclusion, we outline the kind of work that will be required to develop an ethical approach that may bridge the digital divide but avoid the TDC. (shrink)

The idea that certain philosophical debates are "merely verbal" has historically been raised as a challenge against (large parts of) metaphysics. In this paper, I explore an analogous challenge to large parts of epistemology, which is motivated by recent arguments in experimental philosophy. I argue that, while this challenge may have some limited success, it cannot serve as a wedge case for wide-ranging skepticism about the substantiveness of epistemological debates; most epistemological debates are immune to the worries it raises.

This study is dedicated to the chapter Metaphysics My 10, which, in my opinion, represents an example of basic research as regards Aristotle’s ontological investigations. The aim of my analysis is to point out that the chapter constitutes a manifesto for a new ontology: this new ontology is Aristotle’s typological ontology. The main entities of the typological ontology are universals, on the one hand, and instantiations of universals, on the other hand. The ontological levels, to which these two kinds of (...) entities belong, are different from each other: therefore they must be kept rigorously separated from each other. The new ontology constitutes a clear opposition to the ontology of ideas. In my opinion Aristotle does not aim at eliminating universals from the range of the existing entities: At least the universals which correspond to biological kinds (such as „man“ or „animal“) and to all the properties connected to these biological kinds are real entities, even though they do not exist at the same level at which the level of the instantiations do. Aristotle’s aim is thus to assign universals and individuals to different realms of reality. The reality consists both of individuals and of universals: these kinds of entities occupy different realms of reality. (shrink)

This study shows that Aristotle’s introduction of the concept of substance represents a caesura in the history of ontology. The study takes two values for substance into consideration, which are a) substance as an organism (as a biological entity) and b) substance as essence, nature, form of an organism. Substances as organisms are biological concretized properties. Substance as form is the soul directing the organism and the development of the organism; the soul is both the principle of life of the (...) organism and the program which is realized in the organism. The substance as an organism is assigned the central position in Aristotle’s ontology: the organism is not reduced to forces or factors which should have an ontological primacy over the organism; the principle of life and activity of every organism is put into the biological entity and it is not identified with factors that lie outside the organism.

There are various forms of teleological thinking central to debates in the early modern and modern periods, debates in which David Hume (1711–1776) is a key figure. In the first section, we shall introduce three levels at which teleological considerations have been incorporated into philosophical accounts of man and nature, and sketch Hume’s criticisms of these approaches. In the second section, we turn to Hume’s non-teleological ‘science of man’. In the third section, we show how Hume has an account of (...) human flourishing that is not dependent on teleology. In the fourth section, we shall speculate as to the relation between Hume’s account of human nature and contemporary evolutionary accounts of morality and reasoning. (shrink)

In my analysis I deal with some causes and origins of evil and of moral degeneration in the human dimension. My analysis focuses on Plato’s Republic. The origins and causes of the presence of injustice and of vice lie in the very structure of the human soul. The division of the soul into parts which are at least reciprocally independent of each other implies that there is the possibility that they are in conflict with each other. This is the origin (...) of injustice and the root of every form of evil. The correct equilibrium among the parts of the soul, which, in my opinion, are to be interpreted as authentic potencies, can be achieved only by developing the rational part. This development requires a thorough education in philosophy. Throughout my analysis I quote passages in which Plato points out the presence of bad instincts and, in general, of a morally difficult component in our soul. The kind of soul considered in my analysis is the embodied soul. (shrink)

The present essay is the first part of an analysis regarding aspects of Aristotle’s ontology. Aristotle’s ontology is, in my opinion, a formal ontology that examines the fundamental structures of reality and that investigates the features belonging to entities such as substance, quantity, quality, universals. Aristotle’s ontology investigates, moreover, the reciprocal relations existing between these entities. Aristotle’s interpretation of universals is not, in my opinion, a nominalist interpretation of universals: I do not think Aristotle regards universals as being only mental (...) entities. Aristotle, rather, aims at the differentiation between the realms of reality to which individuals and universals belong. In this part of my investigation, I first expose my interpretation of the fundaments of Aristotle’s ontology. Thereafter, I concentrate my attention on chapter Metaphysics Zeta 13: I comment on Aristotle’s investigation regarding the ontological features belonging to the universal qua universal and to the substance qua substance. I analyse the ontological laws that Aristotle finds about universal and substance: substance and universals are considered by Aristotle as mutually incompatible entities. The analysis shows that a false interpretation of the features of the universals endangers the whole ontology. Moreover, the Third-Man-Regress, which is one of the consequences of the misunderstanding of the position of universals in the reality, is regarded as the key to the interpretation of one of Aristotle’s aims: Aristotle aims at the foundation of a typological ontology putting individual entities and universal entities on different levels of reality. The danger of the Third-Man-Regress is avoided through the introduction of a new ontology, that is, through the introduction of the typological ontology of the entities. (shrink)

My essay is a first analysis of the fundaments of the animal ethics. Reflections contained in the studies of Tom Regan, of Peter Singer, of Gary Francione are examined in order to present positions which – despite the differences existing between each other – are in favour of the extension of (at least) some rights to (at least) some kinds of animals. I have chosen the positions of Peter Carruthers in order to present positions being strongly against any extension of (...) rights to whichever kind of animals. This essay will be followed by further investigations. (shrink)

This study deals with the ontological position of predicated entities in comparison with the entities of which they are predicated of. Aristotle strongly criticizes, in some passages of his works, the interpretation that the predicated entities are entities which independently exist of the entities of which they are predicated. Aristotle opposes his interpretation of the universals as entities which does not independently exist, against Plato's ideas, which he interprets as independently existing entities. Aristotle's criticism of Plato's ideas is radical: he (...) does not accept any characteristic of ideas and want them to be expelled from a sane ontology. Aristotle's ontology of instantiation, therefore, completely refuses Plato's ontology of participation. (shrink)

In this paper I will take it for granted that Zagzebski's position articulates a broadly Catholic perspective, and that Plantinga's position accurately represents a broadly Calvinist one. But I will argue that so construed, the Catholic and the Calvinist are much closer than Zagzebski implies: both views are person-based in an important sense of that term; both are internalist on Zagzebski's usage and externalist on the standard usage; and Plantinga's position is consistent with the social elements that Zagzebski stresses in (...) her view. In the second part of the paper I will identify what I think is the real issue between Zagzebski and Plantinga. Namely, Zagzebski thinks that knowledge requires epistemic responsibility, in the sense that instances of knowledge must be appropriately praiseworthy. Plantinga thinks that no such condition is required for knowledge or warranted belief. I will argue that on this issue Zagzebski is right, and that her virtue approach gives us resources for seeing why. Finally, I will look at the consequences for religious knowledge. Here I will argue that the consequences are minimal. Even if knowledge requires responsibility, Plantinga can still make a good case that religious belief is properly basic. And even if religious belief is properly basic, natural theology can still have an important role in the justification of religious belief. (shrink)

In this paper we introduce three methods to approach philosophical problems informationally: Minimalism, the Method of Abstraction and Constructionism. Minimalism considers the specifications of the starting problems and systems that are tractable for a philosophical analysis. The Method of Abstraction describes the process of making explicit the level of abstraction at which a system is observed and investigated. Constructionism provides a series of principles that the investigation of the problem must fulfil once it has been fully characterised by the previous (...) two methods. For each method, we also provide an application: the problem of visual perception, functionalism, and the Turing Test, respectively. (shrink)

In this paper, I examine Eugenio Lecaldano’s way of tackling the issue of the meaning of life. I highlight the dependence of his individualistic approach on the specific character of the person who inquires into the meaning of life. I also sketch a weaker way of understanding the meaning of life as an attempt to provide reasons which are valid from the standpoint of the present, and which will make us continue living.

In this essay, I offer a vindication of pride. I start by presenting the Christian condemnation of pride as the cardinal sin. I subsequently examine Mandeville’s line of argument whereby pride is beneficial to society, although remaining a vice for the individual. Finally, I focus on, and endorse, the analysis of pride formulated by Hume, for whom pride qualifies instead as a virtue. This is because pride not only contributes to making society flourish but also stabilizes the virtuous agent by (...) creating a virtuous circle between our desire for self-appraisal and our aspiration to act morally. I conclude by underscoring the (virtuous) connection between pride and modesty, concomitantly arguing that humility should be discarded as vicious. (shrink)

The problem discussed in this paper arises from the observation that in the course of inter-subjective communication "understanding" seems to be entrusted to the implementation of a real process, not only affective but also cognitive, of processing information contained in the perceived behavior. In a previous study (Greco, 1979) we proposed to consider this process of "reconstruction" of meaning as analogous to the process of "construction" used for oneself. Here we will deal with this process of construction or awareness (...) using theoretical models offered by experimental research. (shrink)

The endeavor of this bibliographical guide is inscribed in the broader effort to reframe the discipline of Philosophy in a global perspective through the account of its history. With the present work readers will gain a broad overview of the materials available in Italian on the histories of philosophy in different regions of the world from the first editions, in the 15th century, to the present. Some of these materials are presented in the extensive introduction to the bibliography, which has (...) been organized according to geographical regions, such as continents and nations, as well as thematic focuses, such as religions, doctrines, or disciplines. Moreover, the introduction discusses two main themes, namely the strong historiographical tradition in Italy and its close connection with political agendas, and the influence of the history of philosophy in the schools. One outcome of the work is the mapping of leading research areas as well as neglected areas, and even the uncovering of some blind spots. (shrink)

This double issue of the journal of hermeneutics and philosophical criticism “Trópos” stems from a workshop held in Padua on November 8th and 9th, 2021, entitled “The Universal and Philosophy,” organized by the Mushin'en Research Group in Intercultural Philosophy (無心円)3, of which the two publishers are founding members.

The basic problem of this investigation concerns how is it that an individual "understands" or "comprehends" what another communicates and, sometimes, even what he does not communicate but of which he has experience. We would like here to take stock of the models that psychology currently has available to study the phenomenon of interpersonal understanding,using a cognitive approach, and to propose some working hypotheses that in our opinion could guide further research.

The tenth volume of the Frontiers of Japanese Philosophy focuses on the theme of “transition,” dealing with transitory and intermediary phenomena and practices such as translation, transmission, and transformation. Written in English, German and Japanese, the contributions explore a wide range of topics, crossing disciplinary borders between phenomenology, linguistics, feminism, epistemology, aesthetics, political history, martial arts, spiritual practice and anthropology, and bringing Japanese philosophy into cross-cultural dialogue with other philosophical traditions. As exercises in “thinking in transition,” the essays reveal novel (...) modes of doing philosophy as a way of boundary crossing that takes transition not only as an object of inquiry, but also as a method of philosophical practice itself.

Review of The Oxford Handbook of Japanese Philosophy by Bret W. Davis (ed.), Oxford University Press, 2022.

Starting from some remarks about the use of models in psychology, Human Information Processing (henceforth called H.I.P.) models which sometimes use computer simulation will be examined. An attempt to show that simulation in psychology does not necessarily imply an H.I.P. approach is then made.

[From SEP]: Contemporary virtue epistemology (hereafter ‘VE’) is a diverse collection of approaches to epistemology. At least two central tendencies are discernible among the approaches. First, they view epistemology as a normative discipline. Second, they view intellectual agents and communities as the primary focus of epistemic evaluation, with a focus on the intellectual virtues and vices embodied in and expressed by these agents and communities. This entry introduces many of the most important results of the contemporary VE research program. These (...) include novel attempts to resolve longstanding disputes, solve perennial problems, grapple with novel challenges, and expand epistemology’s horizons. In the process, it reveals the diversity within VE. Beyond sharing the two unifying commitments mentioned above, its practitioners diverge over the nature of intellectual virtues, which questions to ask, and which methods to use. It will be helpful to note some terminology before proceeding. First, we use ‘cognitive’, ‘epistemic’ and ‘intellectual’ synonymously. Second, we often use ‘normative’ broadly to include not only norms and rules, but also duties and values. Finally, ‘practitioners’ names contemporary virtue epistemologists. (shrink)
