According to epistemic two-dimensionalism, or simply two-dimensionalism, linguistic expressions are associated with two intensions, one of which represents an expression’s a priori implications. The author investigates the prospects of conceptual analysis on the basis of a two-dimensionalist theory of meaning. He discusses a number of arguments for and against two-dimensional semantics and argues that properly construed, two-dimensionalism provides a potent and plausible account of meaning. Against the background of this account, the author then goes on to assess the value of (...) conceptual analysis in philosophical practice, outlining its goals, its promises, but also its limitations.

In light of the problem of logical omniscience, some scholars have argued that belief is question-sensitive: agents don't simply believe propositions but rather believe answers to questions. Hoek (2022) has recently developed a version of this approach on which a belief state is a "web" of questions and answers. Here, we present several challenges to Hoek's question-sensitive account of belief. First, Hoek's account is prone to very similar logical omniscience problems as those he claims to address. Second, the link between (...) belief and action he proposes is too rigid. We close by sketching a generalization of the account that can meet these challenges. (shrink)

This paper critically examines Timothy Williamson’s claim that knowledge figures essentially in explanations of behavior. Since this claim implies that knowledge is causally efficacious in bringing about actions, it plays a key role in Williamson’s case for knowledge being a mental state. I first discuss a central example of Williamson, in which a burglar ransacks a house. I dispute Williamson’s claim that the best explanation of the burglar’s behavior invokes the burglar’s state of knowledge as he enters the house, by (...) arguing that there is a better explanation that only mentions the burglar’s beliefs. Since the reasons that explain the superiority of my proposed explanation generalize, I conclude that one does not have to invoke a subject’s state of knowledge to explain behavior. Nevertheless, Williamson’s explanation is superior to belief-based explanations if one only considers facts that obtain before the action takes place. In the final part of the paper, I argue that this fact does not help Williamson’s case for considering knowledge as a mental state. (shrink)

A recent approach to the problem of logical omniscience holds that belief is question-sensitive: what an agent believes depends on what question they try to answer (Pérez Carballo, 2016; Yalcin, 2018; Hoek, 2022). While the question-sensitive approach can avoid some logical omniscience problems, we argue that it suffers from nearby problems. First, these accounts all validate closure principles that are just as implausible as the ones it was designed to avoid. Second, question-sensitivity by itself isn’t suitable for explaining many kinds (...) of failures of logical omniscience. Recognizing the flaws of this approach, however, naturally leads to a more promising solution. Our account generalizes the question-sensitive approach by appealing to (1) the defeasible nature of dispositions toward action associated with belief and (2) the algorithms an agent uses to make decisions. On our view, then, believing that φ means being disposed to employ an algorithm which outputs acting on the information that φ in normal circumstances associated with φ. We argue that this account naturally generalizes the question-sensitive accounts while avoiding their faults. (shrink)

Many have argued that there is something that is a priori about all necessary truths, including a posteriori necessities. According to a particularly popular claim of this kind, one can know a priori whether a sentence is G-necessary, i.e. whether it is either necessarily true or necessarily false. In this paper, I identify the most plausible version of this claim and I argue that it fails. My discussion also reveals, and depends upon, an important feature of putative natural kind terms (...) that has been widely overlooked. I conclude by outlining a proposal of what is really a priori about necessities. (shrink)

In this paper, we offer a novel defense of descriptivism about reference. Our argument is based on principles about the relevance of speaker intentions to reference that are shared by many opponents of descriptivism, including Saul Kripke. We first show that two such principles that are plausibly endorsed by Kripke and other prominent externalists in fact entail descriptivism. The first principle states that when certain kinds of speaker intentions are present, they suffice to determine and explain reference. According to the (...) second principle, certain speaker intentions must be present whenever something determines or explains reference. We then go on to make these principles more precise and argue that it would be costly to deny either of them. Since on the more precise understanding we suggest, the conjunction of these principles still entails descriptivism, we conclude that opponents of descriptivism have to give up some highly plausible assumption about the relation between speaker intentions and reference.

In this paper, I examine how nudges affect the autonomy and freedom of those nudged. I consider two arguments put forth by Thaler and Sunstein for the claim that these effects can only be minor. According to the first of these arguments, nudges cannot significantly restrict a person’s autonomy or freedom since they are easy to resist. According to the second argument, the existence of nudges is inevitable, and thus, pursuing libertarian paternalism by nudging people doesn’t make a relevant difference (...) to people’s autonomy and freedom. After arguing that both of these arguments fail, I elucidate the general conditions in which, and the degrees to which, a person’s autonomy and freedom are affected by nudges. One focus of this discussion concerns how people’s autonomy and freedom are affected if—for example, due to progress in information technology—nudges become more effective, more individualized and more common, and affect more people.

In this paper, I identify and discuss the following feature of our judgments about hypothetical scenarios concerning the identity of persons: with respect to the vast majority of scenarios, both members of a pair of logically complementary propositions about personal identity are conceivable. I consider a number of explanations of this feature that draw on the metaphysics and the epistemology of personal identity, none of which prove to be satisfactory. I then argue that in order to give an adequate explanation, (...) one needs to recognize an important characteristic of our concept of personal identity: it is such that if there are mental substances (or the like), they constitute personal identity. At the same time, there can still be persons if there are no such substances. Since this finding casts doubts on the way that thought experiments about personal identity are usually set up, I end by outlining its potential consequences for the debate over the identity of persons.

It has long been known that the popular account of egocentric thoughts developed by David Lewis is in conflict with a natural account of communication, according to which successful communication requires the transmission of a thought content from speaker to hearer. In this paper, I discuss a number of proposed attempts to reconcile these two accounts of egocentric thought and communication. Each of them postulates two kinds of mental content, where one is egocentric, and the other is transmitted from speaker (...) to hearer in communication. I argue that Ninan’s account, which involves multi-centered contents, and Kölbel’s and Moss’s accounts, which postulate centered and uncentered proxy contents, respectively, are unsatisfactory. Therefore, I propose a two-dimensionalist account, according to which egocentric thoughts are represented by primary intensions, while the thoughts shared by speaker and hearer in cases of successful communication are represented by secondary intensions. Finally, I argue that aside from being able to reconcile Lewis’s account of egocentric thoughts with the natural account of communication, two-dimensionalism also provides the means for modeling agreement and disagreement.

According to the modal account of propositional apriority, a proposition is a priori if it is possible to know it with a priori justification. Assuming that modal truths are necessarily true and that there are contingent a priori truths, this account has the undesirable consequence that a proposition can be a priori in a world in which it is false. Epistemic two-dimensionalism faces the same problem, since on its standard interpretation, it also entails that a priori propositions are necessarily a (...) priori. In response to this problem, Chalmers and Rabern propose an alternative conception of propositional apriority as well as two-dimensional truth-conditions for apriority statements. Their proposal is also supposed to avoid another problem for the modal account, namely that it entails the existence of false instances of ‘φ iff actually φ’. I discuss Chalmers and Rabern’s account and point out a number of problems with it. I then develop my own account of propositional apriority that solves the problems in question, that can be accepted by friends and foes of two-dimensionalism alike, and that is also neutral with respect to the question of how one construes the objects of propositional apriority.

The epistemic arrow of time is the fact that our knowledge of the past seems to be both of a different kind and more detailed than our knowledge of the future. Just like with the other arrows of time, it has often been speculated that the epistemic arrow arises due to the second law of thermodynamics. In this paper, we investigate the epistemic arrow of time using a fully formal framework. We begin by defining a memory system as any physical (...) system whose present state can provide information about the state of the external world at some time other than the present. We then identify two types of memory systems in our universe, along with an important special case of the first type, which we distinguish as a third type of memory system. We show that two of these types of memory systems are time-symmetric, able to provide knowledge about both the past and the future. However, the third type of memory systems exploits the second law of thermodynamics, at least in all of its instances in our universe that we are aware of. The result is that in our universe, this type of memory system only ever provides information about the past. We also argue that human memory is of this third type, completing the argument. We end by scrutinizing the basis of the second law itself. This uncovers a previously unappreciated formal problem for common arguments that try to derive the second law from the “Past Hypothesis”, i.e., from the claim that the very early universe was in a state of extremely low entropy. Our analysis is indebted to prior work by one of us but expands and improves upon this work in several respects. (shrink)

In this paper, I argue that, contrary to Robert Stalnaker’s highly influential account of linguistic communication, successful communication does not depend on a common ground between speaker and hearer. The problem for Stalnaker’s account manifests itself in communicative situations that represent both Lingens cases, i.e., cases involving egocentric beliefs, and Frege cases, i.e., cases involving identity confusions. I describe two hypothetical cases that involve successful communication, but in which no common ground of the kind required by Stalnaker’s account is available. (...) I therefore propose an alternative account of communication that is based on epistemic two-dimensionalism. This account maintains that communication requires the transfer of a thought content from speaker to hearer. By holding that this shared content often constitutes common ground, it preserves much of the appeal of Stalnaker’s account. However, my account allows for cases in which the shared thought content does not figure in common ground. (shrink)

My paper discusses large-scale nudging, i.e., the use of nudges that are highly individualized, highly prevalent, and highly effective. As I explain, digital environments are ideally suitable for large-scale nudging. I argue that large-scale digital nudging has the potential to compromise our freedom, by undermining our control over our actions. I end by sketching what could be done to avoid the development and the use of such nudges, to preserve our freedom. -/- .

In the essay, I compare the aims and especially the methods of philosophers and grammarians. It transpires that there are several interesting similarities to be found with the method and aim in particular of traditional 'armchair philosophers'. I argue that these similarities go far enough to suggest that if armchair philosophers' method is in a state of challenge, as is claimed by a number of experimental philosophers, then the same can be said about the method of grammarians. However, I also (...) try to show that it is not easy for experimental philosophers to frame their critique in a way that avoids construing its target too broadly, which would lead to unacceptable consequences. I conclude with some brief remarks on the extent to which a properly targeted critique can provide a challenge for traditional philosophical method. (shrink)

In his earlier writings, Fred Dretske proposed an anti-skeptical strategy that is based on a rejection of the view that knowledge is closed under known entailment. This strategy is seemingly congenial with a sensitivity condition for knowledge, which is often associated with Dretske’s epistemology. However, it is not obvious how Dretske’s early account meshes with the information-theoretic view developed in Knowledge and the Flow of Information. One aim of this paper is to elucidate the connections between these accounts. First I (...) argue that, contrary to an objection raised by Christoph Jäger, the information-theoretic account is compatible with Dretske’s anti-skeptical strategy based on the rejection of closure. This strategy invokes the notion of channel conditions, which are roughly speaking those conditions that are necessary and jointly sufficient for a signal to carry information. I propose an interpretation of the account that is based on the idea that a signal’s carrying information requires that the channel conditions are stable. It is shown that the resulting account incorporates both a sensitivity condition and a safety condition for knowledge. Finally, I demonstrate how this proposal allows for knowledge of modally robust propositions without making its acquisition too easy, as simple safety accounts do. I end with a suggestion concerning the direction that future research should take, based on the fact that in its present form the information-theoretic account does not capture inferential knowledge.

Chalmers has argued that Bayesianism supports the existence of a priori truths, since it entails that scrutability conditionals are not rationally revisable. However, as we argue, Chalmers's arguments leave open that every proposition is rationally deniable, which would be devastating for large parts of his philosophical program. We suggest that Chalmers should appeal to well-known convergence theorems to argue that ideally rational subjects converge on the truth of scrutability conditionals. However, our discussion reveals that showing that these theorems apply in (...) effect requires assuming scrutability. Consequently, Bayesianism doesn't conflict with Chalmers's scrutability framework, but it doesn't support it, either. (shrink)

The main goal of my paper is to argue that data compression is a necessary condition for intelligence. One key motivation for this proposal stems from a paradox about intuition and intelligence. For the purposes of this paper, it will be useful to consider playing board games—such as chess and Go—as a paradigm of problem solving and cognition, and computer programs as a model of human cognition. I first describe the basic components of computer programs that play board games, namely (...) value functions and search functions. I then argue that value functions both play the same role as intuition in humans and work in essentially the same way. However, as will become apparent, using an ordinary value function is just a simpler and less accurate form of relying on a database or lookup table. This raises our paradox, since reliance on intuition is usually considered to manifest intelligence, whereas usage of a lookup table is not. I therefore introduce another condition for intelligence that is related to data compression. This proposal allows that even reliance on a perfectly accurate lookup table can be nonintelligent, while retaining the claim that reliance on intuition can be highly intelligent. My account is not just theoretically plausible, but it also captures a crucial empirical constraint. This is because all systems with limited resources that solve complex problems—and hence, all cognitive systems—need to compress data. (shrink)

Two-dimensional semantic theories distinguish between two different aspects, or ‘dimensions’, of the meaning of linguistic expressions. Many other theories identify the meaning of an expression with a dependency of its extension on the state of the world. (The extension of a sentence is its truth-value, and the extension of a sub-sentential expression … Continue reading Semantics, Two-Dimensional →.

Philosophen berufen sich in Gedankenexperimenten oft auf Intuitionen. Doch werden diese Intuitionen auch von anderen Philosophen oder von philosophischen Laien geteilt? Und durch welche Faktoren werden sie eigentlich bestimmt? Experimentelle Philosophen gehen solchen Fragen seit einigen Jahren mit empirischen Methoden auf den Grund. Ihre Ergebnisse sind mitunter verblüffend und haben für Aufsehen gesorgt. Der vorliegende Band lässt führende Vertreter und Gegner dieser wachsenden Bewegung zu Wort kommen und will die bislang überwiegend englischsprachige Debatte verstärkt in die deutsche Philosophie hineintragen.

What is the relationship between the world and logic, between intuition and language, between objects and their quantitative determinations? Rationalists, on the one hand, hold that the world is structured in a rational way. Representationalists, on the other hand, assume that language, logic, and mathematics are only the means to order and describe the intuitively given world. In World and Logic, Jens Lemanski takes up three surprising arguments from Arthur Schopenhauer’s hitherto undiscovered Berlin Lectures, which concern the philosophy of (...) language, logic, and mathematics. Based on these arguments, Lemanski develops a new position entitled ‘rational representationalism’: the world is always structured by human beings according to linguistic, logical, and mathematical principles, but the basic vocabulary of these structural descriptions already contains metaphors taken from the world around us.

This paper analyses a hitherto unknown technique of using logic diagrams to create argument maps in eristic dialectics. The method was invented in the 1810s and -20s by Arthur Schopenhauer, who is considered the originator of modern eristic. This technique of Schopenhauer could be interesting for several branches of research in the field of argumentation: Firstly, for the field of argument mapping, since here a hitherto unknown diagrammatic technique is shown in order to visualise possible situations of arguments in a (...) dialogical controversy. Secondly, the art of controversy or eristic, since the diagrams do not analyse the truth of judgements and the validity of inferences, but the persuasiveness of arguments in a dialogue. (shrink)

Eristic has been studied more and more intensively in recent years in philosophy, law, communication theory, logic, proof theory, and A.I. Nevertheless, the modern origins of eristic, which almost all current researchers see in the philosopher Arthur Schopenhauer, are considered to be a theory of the illegitimate use of logical and rhetorical devices. Thus, eristic seems to violate the norms of discourse ethics. In this paper, I argue that this interpretation of eristic is based on prejudices that contradict the original (...) intention of modern eristic. Eristic is not an art of being right or winning an argument, but an art of protecting oneself from the one who deliberately violates norms of discourse ethics to gain argumentative acceptance. For this reason, eristic must be seen as a discipline of Enlightenment philosophy and a correlate of discourse ethics. Especially in the age of alternative facts and post-factual politics, this makes eristic a valuable discipline. (shrink)

This paper presents an analysis of Seneca's 58th letter to Lucilius and Porphyry's Isagoge, which were the origin of the tree diagrams that became popular in philosophy and logic from the early Middle Ages onwards. These diagrams visualise the extent to which a concept can be understood as a category, genus, species or individual and what the method of dihairesis (division) means. The paper explores the dissimilarities between Seneca's and Porphyry's tree structures, scrutinising them through the perspective of modern graph (...) theory. Although traditional trees can be interpreted in a modern way, their terms and definitions defy modern standardisation. These distinctions are not only useful for differentiating between Seneca's and Porphyry's trees, but also for comprehending the evolution of this philosophical tradition. Thus the paper highlights the continued significance of these tree diagrams in analysing concepts and categories in philosophy and structuring objects and information in modern fields such as artificial intelligence, computer science, bioinformatics, graph theory, and many more.

Reism or concretism are the labels for a position in ontology and semantics that is represented by various philosophers. As Kazimierz Ajdukiewicz and Jan Woleński have shown, there are two dimensions with which the abstract expression of reism can be made concrete: The ontological dimension of reism says that only things exist; the semantic dimension of reism says that all concepts must be reduced to concrete terms in order to be meaningful. In this paper we argue for the following two (...) theses: (1) Arthur Schopenhauer has advocated a reistic philosophy of language which says that all concepts must ultimately be based on concrete intuition in order to be meaningful. (2) In his semantics, Schopenhauer developed a theory of logic diagrams that can be interpreted by modern means in order to concretize the abstract position of reism. Thus we are not only enhancing Jan Woleński’s list of well-known reists, but we are also adding a diagrammatic dimension to concretism, represented by Schopenhauer. (shrink)

In this paper, I investigate whether we can use a world-involving framework to model the epistemic states of non-ideal agents. The standard possible-world framework falters in this respect because of a commitment to logical omniscience. A familiar attempt to overcome this problem centers around the use of impossible worlds where the truths of logic can be false. As we shall see, if we admit impossible worlds where “anything goes” in modal space, it is easy to model extremely non-ideal agents that (...) are incapable of performing even the most elementary logical deductions. A much harder, and considerably less investigated challenge is to ensure that the resulting modal space can also be used to model moderately ideal agents that are not logically omniscient but nevertheless logically competent. Intuitively, while such agents may fail to rule out subtly impossible worlds that verify complex logical falsehoods, they are nevertheless able to rule out blatantly impossible worlds that verify obvious logical falsehoods. To model moderately ideal agents, I argue, the job is to construct a modal space that contains only possible and non-trivially impossible worlds where it is not the case that “anything goes”. But I prove that it is impossible to develop an impossible-world framework that can do this job and that satisfies certain standard conditions. Effectively, I show that attempts to model moderately ideal agents in a world-involving framework collapse to modeling either logical omniscient agents, or extremely non-ideal agents. (shrink)

The Oxford Handbook of Carl Schmitt collects thirty original chapters on the diverse oeuvre of one of the most controversial thinkers of the twentieth century. Carl Schmitt was a German theorist whose anti-liberalism continues to inspire scholars and practitioners on both the Left and the Right. Despite Schmitt's rabid anti-semitism and partisan legal practice in Nazi Germany, the appeal of his trenchant critiques of, among other things, aestheticism, representative democracy, and international law as well as of his theoretical justifications of (...) dictatorship and rule by exception is undiminished. Uniquely located at the intersection of law, the social sciences, and the humanities, this volume brings together sophisticated yet accessible interpretations of Schmitt's sprawling thought and complicated biography. The contributors hail from diverse disciplines, including art, law, literature, philosophy, political science, and history. In addition to opening up exciting new avenues of research, The Oxford Handbook of Carl Schmitt provides the intellectual foundations for an improved understanding of the political, legal, and cultural thought of this most infamous of German theorists. A substantial introduction places the trinity of Schmitt's thought in a broad context. (shrink)

The counterfactual comparative account of harm has counterintuitive implications in cases involving overdetermination and preemption. A popular strategy for dealing with these problems appeals to plural harm—several events being jointly harmful. Björn Petersson criticizes this strategy on the grounds that it conflicts with a strong intuition that helps to motivate the counterfactual comparative account, namely, that harming someone essentially involves making a difference for the worse for her. In this paper, I argue that Petersson’s argument is unconvincing.

Logic diagrams have been increasingly studied and applied for a few decades, not only in logic, but also in many other fields of science. The history of logic diagrams is an important subject, as many current systems and applications of logic diagrams are based on historical predecessors. While traditional histories of logic diagrams cite pioneers such as Leibniz, Euler, Venn, and Peirce, it is not widely known that Kant and the early Kantians in Germany and England played a crucial role (...) in popularising Euler(-type) diagrams. In this paper, the role of the Kantians in the late eighteenth and early nineteenth centuries will be analysed in more detail. It shows that diagrams (or intuition in general) were a highly contentious topic that depend on the philosophical attitude and went beyond logic to touch on issues of physics, metaphysics, linguistics and, above all, mathematics.

Plotinus (204-70) is the founder of Neoplatonism and its most significant thinker. He shaped late antique philosophy and significantly influenced the entire metaphysical tradition of the Middle Ages, Renaissance, and German Idealism. In this volume, Jens Halfwassen presents Plotinus' life and work, as well as the most important aspects of his historical influence. Issues of key importance for the Neoplatonists-such as the interaction between Being and Thought, the ascent of the soul, and the interpretation of Plato's theory of principles-are (...) explained in detail in the course of outlining the Neoplatonic metaphysical system. The introduction outlines Halfwassen's significant contribution to the study of Plotinus, paying particular attention to the differences between the current German and Anglophone approaches to the Platonic tradition.

The paper gives an overview of Arthur Schopenhauer's theory of rationality. For Schopenhauer, rationality is a human faculty based on language, which, in addition to language, is primarily concerned with knowledge or philosophy of science and practical action. For Schopenhauer, language is the umbrella term under which he subsumes logic and eristics. This paper will first introduce Schopenhauer's logic and clarify its connection to the philosophy of language. This is followed by eristic dialectics, which reflects on how one can protect (...) oneself from people who argue irrationally in a goal-oriented way. Schopenhauer's philosophy of mathematics belongs to the field of philosophy of science. Unlike many other authors of his time, Schopenhauer does not advocate a rationalist but a representationalist approach, which, however, includes a theory of rationality. Therefore, Schopenhauer's representationalist approach will finally be discussed, emphasizing its relationship to his theory of rationality. (shrink)

Advanced AI systems are rapidly making their way into medical research and practice, and, arguably, it is only a matter of time before they will surpass human practitioners in terms of accuracy, reliability, and knowledge. If this is true, practitioners will have a prima facie epistemic and professional obligation to align their medical verdicts with those of advanced AI systems. However, in light of their complexity, these AI systems will often function as black boxes: the details of their contents, calculations, (...) and procedures cannot be meaningfully understood by human practitioners. When AI systems reach this level of complexity, we can also speak of black-box medicine. In this paper, we want to argue that black-box medicine conflicts with core ideals of patient-centered medicine. In particular, we claim, black-box medicine is not conducive for supporting informed decision-making based on shared information, shared deliberation, and shared mind between practitioner and patient.

Multimodal communication research focuses on how different means of signalling coordinate to communicate effectively. This line of research is traditionally influenced by fields such as cognitive and neuroscience, human-computer interaction, and linguistics. With new technologies becoming available in fields such as natural language processing and computer vision, the field can increasingly avail itself of new ways of analyzing and understanding multimodal communication. As a result, there is a general hope that multimodal research may be at the “precipice of greatness” due (...) to technological advances in computer science and resulting extended empirical coverage. However, for this to come about there must be sufficient guidance on key (theoretical) needs of innovation in the field of multimodal communication. Absent such guidance, the research focus of computer scientists might increasingly diverge from crucial issues in multimodal communication. With this paper, we want to further promote interaction between these fields, which may enormously benefit both communities. The multimodal research community (represented here by a consortium of researchers from the Visual Communication [ViCom] Priority Programme) can engage in the innovation by clearly stating which technological tools are needed to make progress in the field of multimodal communication. In this article, we try to facilitate the establishment of a much needed common ground on feasible expectations (e.g., in terms of terminology and measures to be able to train machine learning algorithms) and to critically reflect possibly idle hopes for technical advances, informed by recent successes and challenges in computer science, social signal processing, and related domains.

This work is a systematic investigation of a range of solutions offered today for the philosophical problem of mental causation. The premises constituting the problem are analyzed before a survey is developed of the most popular theories on mental causation. It is demonstrated in detail why most of these canonical solutions must be considered deficient. In a third part, the 'new compatibilist's' approach to mental causation is explored, which is characterized by assertion of a non-identity-but-non-distinctness principle. The last part aims (...) to offer an alternative solution to the problem. On the basis of a certain set of counterfactual conditionals, which are jointly taken to provide a definition of 'causal proportionality' that improves the existing definitions, it is shown that a specific, and hitherto widely neglected, version of causal overdeterminationism must be considered the most successful solution to the problem of mental causation.

This book marks the inauguration of the Historia Logicae book series, which seeks to publish high-quality monographs, dissertations, textbooks, proceedings, and anthologies on the history of logic in either German or English. Serving as the inaugural volume in this series, the book explores the contemporary interpretation of logic across many centuries and cultures. The first section of the volume comprises a compilation of papers dedicated to ancient and medieval logic, examining prominent thinkers such as Plato, Aristotle, Seneca, Porphyry, Proclus, Boethius, (...) Buridan, and Kilwardby. The second section shifts focus towards early-modern and contemporary logics, including the works of Caramuel, Kant, Drobisch, Husserl, and Jaskowski. Topics of discussion encompass the relationship between mathematics and logic, natural deduction, intuitionism, graph theory, categorical judgments, theories of truth, modal logic, opposition relations, logic diagrams, definitions of formal logic, many-sorted logic, model theory, and paraconsistent logic.

Nowadays, the forms assumed by knowledge indicate an unhinging of traditional structures conceived on the model of discipline. Consequently, what was once strictly disciplinary becomes interdisciplinary, what was homogeneous becomes heterogeneous and what was hierarchical becomes heterarchical. When we look for a matrix of interdisciplinarity, that is to say, a primary basis or an essential dimension of all the complex phenomena we are surrounded by, we see the need to break with the disciplinary self-restraint in which, often completely inadvertently, many (...) of us lock ourselves up, remaining anchored to our own competences, ignoring what goes beyond our own sphere of reference. However, interdisciplinarity is still a vague concept and a much demanding practice. It presupposes the continuous search for convergent theoretical perspectives and methodologies, and the definition of common spaces and languages, as well as a true dialogical and open mind of several scholars. From ethics to science, from communication to medicine, from climate change to human evolution the volume Controversies and Interdisciplinarity offers a series of original insights beyond disciplinary fragmentation for a new knowledge model.

The traditional Lewis–Stalnaker semantics treats all counterfactuals with an impossible antecedent as trivially or vacuously true. Many have regarded this as a serious defect of the semantics. For intuitively, it seems, counterfactuals with impossible antecedents—counterpossibles—can be non-trivially true and non-trivially false. Whereas the counterpossible "If Hobbes had squared the circle, then the mathematical community at the time would have been surprised" seems true, "If Hobbes had squared the circle, then sick children in the mountains of Afghanistan at the time would (...) have been thrilled" seems false. Many have proposed to extend the Lewis–Stalnaker semantics with impossible worlds to make room for a non-trivial or non-vacuous treatment of counterpossibles. Roughly, on the extended Lewis–Stalnaker semantics, we evaluate a counterfactual of the form "If A had been true, then C would have been true" by going to closest world—whether possible or impossible—in which A is true and check whether C is also true in that world. If the answer is "yes", the counterfactual is true; otherwise it is false. Since there are impossible worlds in which the mathematically impossible happens, there are impossible worlds in which Hobbes manages to square the circle. And intuitively, in the closest such impossible worlds, sick children in the mountains of Afghanistan are not thrilled—they remain sick and unmoved by the mathematical developments in Europe. If so, the counterpossible "If Hobbes had squared the circle, then sick children in the mountains of Afghanistan at the time would have been thrilled" comes out false, as desired. In this paper, I will critically investigate the extended Lewis–Stalnaker semantics for counterpossibles. I will argue that the standard version of the extended semantics, in which impossible worlds correspond to maximal, logically inconsistent entities, fails to give the correct semantic verdicts for many counterpossibles. In light of the negative arguments, I will then outline a new version of the extended Lewis–Stalnaker semantics that can avoid these problems. (shrink)

This paper argues in favor of a hybrid conception of identity. A common conception of identity in datafied society is a split between a digital self and a real self, which has resulted in concepts such as the data double, algorithmic identity, and data shadows. These data-identity metaphors have played a significant role in the conception of informational privacy as control over information—the control of or restricted access to your digital identity. Through analyses of various data-identity metaphors as well as (...) philosophical accounts of identity, we argue in favor of a hybrid conception of identity that emphasizes the relations between the ‘real’ and the ‘digital’. A hybrid conception of identity—where the digital is an aspect on par with social relations, self-understanding, and values—ultimately calls for an understanding of privacy as the right to influence one’s own identity.
