Infants can see someone pointing to one of two buckets and infer that the toy they are seeking is hidden inside. Great apes do not succeed in this task, but, surprisingly, domestic dogs do. However, whether children and dogs understand these communicative acts in the same way is not yet known. To test this possibility, an experimenter did not point, look, or extend any part of her body towards either bucket, but instead lifted and shook one via a centrally pulled (...) rope. She did this either intentionally or accidentally, and did or did not address her act to the subject using ostensive cues. Young 2-year-old children but not dogs understood the experimenter’s act in intentional conditions. While ostensive pulling of the rope made no difference to children’s success, it actually hindered dogs’ performance. We conclude that while human children may be capable of inferring communicative intent from a wide variety actions, so long as these actions are performed intentionally, dogs are likely to be less flexible in this respect. Their understanding of communicative intention may be more dependent upon bodily markers of communicative intent, including gaze, orientation, extended limbs, and vocalisations. This may be because humans have come under selective pressure to develop skills for communicating with absent interlocutors – where bodily co-presence is not possible. (shrink)

There is a long-standing disagreement among Branching-Time theorists. Even though they all believe that the branching representation accurately grasps the idea that the future, contrary to the past, is open, they argue whether this representation is compatible with the claim that one among many possible futures is distinguished—the single future that will come to be. This disagreement is paralleled in an argument about the bivalence of future contingents. The single, privileged future is often called the Thin Red Line. I reconstruct (...) the history of the arguments for and against this idea. Then, I propose my own version of the Thin Red Line theory which is immune to the major objections found in the literature. I argue that the semantic disagreement is grounded in distinct metaphysical presuppositions. My solution is expressed in a conceptual framework proposed by John MacFarlane, who distinguishes semantics from postsemantics. I extend his distinction and introduce a new notion of presemantics to elucidate my idea. (shrink)

The purpose of the paper is to rethink the role of actuality in the branching model of possibilities. We investigate the idea that the model should be enriched with an additional factor—the so-called Thin Red Line—which is supposed to represent the single possible course of events that gets actualized in time. We believe that this idea was often misconceived which prompted some unfortunate reactions. On the one hand, it suggested problematic semantic models of future tense and and on the other, (...) it provoked questionable lines of criticism. We reassess the debate and point to potential pitfalls, focusing on the semantic dimension of the Thin Red Line theory. Our agenda transcends the semantics, however. We conclude that semantic considerations do not threaten the Thin Red Line theory and that the proper debate should be carried in the domain of metaphysics. (shrink)

We investigate the semantics of historical counterfactuals in indeterministic contexts. We claim that "plain" and "necessitated" counterfactuals differ in meaning. To substantiate this claim, we propose a new semantic treatment of historical counterfactuals in the Branching Time framework. We supplement our semantics with supervaluationist postsemantics, thanks to which we can explain away the intuitions which seem to talk in favor of the identification of "would" with "would necessarily".

In the present essay, while entering into discussion with William Hasker, I addressed two divine dilemmas in “the pre-creation situation.” My considerations focused on the reasons for creating a world—the love reason and the manifestation reason—which in some way prevailed over the reasons against creating a world and whose concurrence prompted the image of an optimal creatable world. It turns out that the latter resembles both our world and the world suggested by Hasker’s theism. In that world, God has brought (...) to existence both what is unworthy and what displays high degrees of excellence. On this view, the eschatological conclusion of the world would be the full actualization of divine grace and of the manifestation of God. In the final part of the essay, I attempted to show that my view does not entail the rejection of the idea of divine impassibility. (shrink)

Entscheidungen verweisen in einem begrifflichen Sinne auf Gründe. Entscheidungssysteme bieten eine probabilistische Verlässlichkeit als Rechtfertigung von Empfehlungen an. Doch nicht für alle Situationen mögen Verlässlichkeitsgründe auch angemessene Gründe sein. Damit eröffnet sich die Idee, die Güte von Gründen von ihrer Angemessenheit zu unterscheiden. Der Aufsatz betrachtet an einem Beispiel, einem KI-Lügendetektor, die Frage, ob eine (zumindest aktuell nicht gegebene) hohe Verlässlichkeit den Einsatz rechtfertigen kann. Gleicht er nicht einem Richter, der anhand einer Statistik Urteile fällen würde?

Blumenbergs Paradigmen zu einer Metaphorologie sind bekannt für die Entdeckung absoluter Metaphern. Zahlreiche systematische Fragen mögen dabei offen geblieben sein, etwa die nach verschiedenen Typen1 von Metaphern oder den Methoden ihrer Interpretation, so dass schon bezweifelt wurde, ob es sich überhaupt um eine Metapherntheorie handle.2 Immerhin: Dass es absolute Metaphern gibt, was diese sind und woran sie erkannt werden können, wird von Blumenberg in großer Prägnanz und anhand zahlreicher Beispiele dargestellt. Wenn es eine unangetastete Gewissheit in der Blumenbergrezeption gibt, so (...) scheint sie hierin zu finden zu sein. Dennoch möchte ich erneut die Frage an Blumenbergs Text stellen: In welchem Sinn ist eine Metapher absolut? Auf den ersten Blick mag diese Frage überraschen, da sie einen der offensichtlichsten Gedanken Blumenbergs berührt: Eine absolute Metapher ist nach Blumenberg eine solche, die sich nicht in Begriffe rückübersetzen lässt. In diesem Sinne wird sie von ihm als absolut charakterisiert. Warum halte ich dennoch diese Frage für berechtigt? Das wird am besten anhand einer Alternative verdeutlicht: Ist die absolute Metapher ein Ausdruck in einem fremden Kontext, wie Blumenbergs zahlreiche Exempel nahelegen (die Kraft der Wahrheit, die nackte Wahrheit), oder ist die absolute Metapher gleichsam die jeweilige ganze Theorie, bündelt sich in ihr der gesamte Text? Auf den ersten Blick mag diese Alternative paradox erscheinen. Vorgreifend sei der ihr zugrundeliegende Gedanke erläutert: Blumenbergs Darstellung der Fundstellen legt zunächst die erste Lesart nahe. Demnach wäre die absolute Metapher das Vorkommen eines Ausdrucks (wie »Kraft« oder »nackt«) in einem Kontext, in den sie zunächst nicht passt (Wahrheit). Die Metapher wäre dann zwar nicht ein Ausdruck allein, sondern ein Ausdruck in einem ihm fremden Kontext; sie wiese jedoch Grenzen auf. Wie unbestimmt diese auch verliefen, ob sie weiter oder enger anzusetzen wäre, sie wäre lokalisier- und daher identifizierbar. Die zweite Lesart motiviert sich zunächst dadurch, dass Blumenberg vorführt, dass eine absolute Metapher gegeben sein kann, ohne dass sie als Ausdruck in einem Text vorkommt. Sie bildet dann dessen »implikatives Modell«; das heißt, sie stellt den Hintergrund der Begriffsbildung dar und entwirft das Verhältnis von Selbst und Welt. Was zunächst einen Sonderfall darstellt (Metapher ohne Ausdruck), verweist jedoch auf eine allgemeine Eigenschaft absoluter Metaphern bei Blumenberg: Diese sind Modelle für das Verhältnis von Ich und Welt und erfüllen dadurch theoretische und pragmatische Funktionen. Als solche ist die absolute Metapher nicht auf ein lokales Vorkommen begrenzt, sondern durchdringt den Text als solchen. Beide Möglichkeiten stehen in einem Gegensatz zueinander. Gleichwohl gibt es einen ver- mittelnden Gedanken: Die absolute Metapher (als Strukturzusammenhang des gesamten Textes verstanden) kann sich gleichsam in einem Ausdruck manifestieren, verdichten und selbst bezeichnen. Aber das Vorkommen von absoluten Metaphern wäre an das Vorkommen von Ausdrücken in einem fremden Kontext nicht gebunden. Die Diskussion dieser Frage steht im Zentrum des Beitrags (Abschnitte 1–2), sie hat Konsequenzen für zwei Gedanken (Abschnitte 3–4), die in ihrem Licht vielleicht klarer hervortreten. (shrink)

We deal with the modal logic of cluster-decomposable Kripke interpretations, present an axiomatization, and prove some additional results regarding this logic.

Scientificity is essentially methodology. The use of information technology as methodological instruments in science has been increasing for decades, this raises the question: Does this transform science? This question is the subject of the Special Issue in Minds and Machines “The epistemological significance of methods in computer simulation and machine learning”. We show that there is a technological change in this area that has three methodological and epistemic consequences: methodological opacity, reproducibility issues, and altered forms of justification.

Broken trust elicits two types of responses: On the one hand, an epistemic response: How could I be so mistaken? How can I learn to trust more appropriately? On the other hand, a moral response: How could you deceive me so deeply and hurt me so profoundly? Even though the response in a given case may be more epistemically or morally emphasized, their interrelation raises two theoretically challenging questions: (1) How can a unity of the epistemic and normative dimensions of (...) trust be reflected in theories; thus far, these dimensions tend to diverge in predominant approaches that model trust either epistemically or normatively (e.g. evidential vs. assurance view). (2) How can it be understood that it is constitutive of trust that it can be broken, and that it is constitutive of trust that there is no risk in the very essence of trusting. The present paper proposes a response to these two questions. (shrink)

We present an embedding of the Lambek–Grishin calculus into an extension of the nonassociative Lambek calculus with negation. The embedding is based on the De Morgan interpretation of the dual Grishin connectives.

In the current paper, I enter into debate with Marcin Tkaczyk and the chosen Anglo-Saxon analytic philosophers of religion to discuss the theological version of the problem of future contingents. I take into consideration some varieties of Ockhamism (retroactivism)—the position denying the temporal necessity (non-determination) of all past events and allowing some form of retroactivity. Strong Ockhamism postulates real retroactive causation, moderate Ockhamism limits it to the meanings of physical and psychical events, and weak Ockhamism replaces the notion of retroactive (...) causation with that of retroactive dependence. I compare different forms of retroactivism with eternalism (of Boethius, St. Anselm of Canterbury, and St. Thomas Aquinas) to show that the latter has significant advantage. At the same time, I point out that eternalism in its presentist and relativist version (proposed by Brian Leftow) avoids the objections put forward against it, and that, within such eternalism, the problem of future contingents does not arise.

Debates on new technologies commonly seem to be irrational. In an even higher degree this might be true for the expectations that are evoked by recent biotechnologies. A typical constellation is like this: While A expresses fears concerning a new technology, those fears are taken up to be absurd by B. And while B criticizes that A?s scenarios lack a realistic basis, A complains about not being taken serious. Thus the conflicting parties accuse each other of behaving irrational or even (...) malicious. This article deals with this mutual suspicion of irrationality and provides an explanation focusing on structural reasons for conflicts of that kind. An explanation is reached on the basis of a model that describes the genesis of expectations regarding technological potentials. These expectations are concerned with the anticipation that a technology has the power to fundamentally change our life. Based on this model a different examination of discourses on technologies is possible: The existence of structurally different levels of communication about technology is demonstrated - plus that the levels themselves can stay undiscovered by the conflicting groups due to structural reasons. And as the levels in communication remain concealed the impression of a slippery slope of rationality prevails. nema. (shrink)

Blumenberg has sometimes described his work as a phenomenology of history. The connection between history and phenomenology is particularly striking in the context of Blumenberg’s contributions to the philosophy of technology. In the course of his analysis of Husserl’s Krisis, Blumenberg develops, as my contribution aims to show, a conception of history in which complete technologization leads to a perfected lifeworld. Blumenberg formulates this partly explicitly within the framework of a three-stage model of history, but there are also implicit insights (...) in Blumenberg’s texts that seem to work with such a structuring of history.

Naturalism is currently the most vibrantly developing approach to philosophy, with naturalised methodologies being applied across all the philosophical disciplines. One of the areas naturalism has been focussing upon is the mind, traditionally viewed as a topic hard to reconcile with the naturalistic worldview. A number of questions have been pursued in this context. What is the place of the mind in the world? How should we study the mind as a natural phenomenon? What is the significance of cognitive science (...) research for philosophical debates? In this book, philosophical questions about the mind are asked in the context of recent developments in cognitive science, evolutionary theory, psychology, and the project of the naturalisation. Much of the focus is upon what we have learned by studying natural mental mechanisms as well as designing artificial ones. In the case of natural mental mechanisms, this includes consideration of such issues as the significance of deficits in these mechanisms for psychiatry. The significance of the evolutionary context for mental mechanisms as well as questions regarding rationality and wisdom is also explored. Mechanistic and functional models of the mind are used to throw new light on discussions regarding issues of explanation, reduction and the realisation of mental phenomena. Finally, naturalistic approaches are used to look anew at such traditional philosophical issues as the correspondence of mind to world and presuppositions of scientific research. (shrink)

We study structural rules in the context of multi-valued logics with finitely-many truth-values. We first extend Gentzen’s traditional structural rules to a multi-valued logic context; in addition, we propos some novel structural rules, fitting only multi-valued logics. Then, we propose a novel definition, namely, structural rules completeness of a collection of structural rules, requiring derivability of the restriction of consequence to atomic formulas by structural rules only. The restriction to atomic formulas relieves the need to concern logical rules in the (...) derivation. (shrink)

In 1953, exactly 50 years ago to this day, the first volume of Studia Logica appeared under the auspices of The Philosophical Committee of The Polish Academy of Sciences. Now, five decades later the present volume is dedicated to a celebration of this 50th Anniversary of Studia Logica. The volume features a series of papers by distinguished scholars reflecting both the aim and scope of this journal for symbolic logic.

On the 11th of January, 2001 the Philosophical Circle of the University School of Philosophy and of Education Ignatianum in Cracow organised a philosophical symposium on: The subject of metaphysics and the way of its determination. This problem seems important nowadays, although it has been discussed throughout the whole philosophical tradition. Solutions concerning basic philosophical problems have their impact on the understanding of reality, first of all the human being and the culture created by him which is expressed in knowledge, (...) morality, arts and religion. Reflection on the foundations of philosophy is especially important in the contemporary intellectual climate which is dominated by relativism and nihilism. This is demonstrated by Pope John Paul II in his encyclical Fides et Ratio, which also proposes the way of overcoming the crisis through the return to the philosophy of being, that is metaphysics. The guests invited to the symposium belong to the above-mentioned philosophical trend. (shrink)

The paper presents a generalization of pregroup, by which a freely-generated pregroup is augmented with a finite set of commuting inequations, allowing limited commutativity and cancelability. It is shown that grammars based on the commutation-augmented pregroups generate mildly context-sensitive languages. A version of Lambek’s switching lemma is established for these pregroups. Polynomial parsability and semilinearity are shown for languages generated by these grammars.

Specialists on issues of sexual abuse in religious institutions unanimously stress that this kind of experience significantly affects the victims’ spirituality. Particularly devastating and distorting for their spirituality is sexual abuse committed by clergy. In order to explore this issue for the first time in Poland, the authors conducted a qualitative study in the form of semi-structured interviews with five women who had experienced sexual abuse by Catholic clergy and/or religious in adolescence and young adulthood. The interviews were analyzed using (...) the interpretative phenomenological analysis and narrative methodology. The results showed that four respondents experienced or had experienced religious struggles in three areas: interpersonal, intrapsychic, and relationship with God. These struggles are complex and intense enough to be referred to as “spiritual trauma”, “religious trauma”, or “spiritual violence”. The results of the study may be of importance for people helping or having any other kind of contact with victims of clergy sexual abuse. (shrink)

In my paper, I show three concepts of patriotism present in the Lvov-Warsaw School, and try to indicate how these concepts differed and what norms they were involved in, as well as to evaluate the justifications indicated for these norms.

Artykuł jest próbą nakreślenia różnych sposobów konstruowania światów w wybranych utworach literackich i filmowych. Roger Caillois i – nieco później – Stanisław Lem dokonali dość szczegółowego rozróżnienia metod kreowania literackich światów, ze względu na ich gatunkowe zróżnicowanie. Inaczej konstruowane są zasady rządzące rzeczywistością w utworach kryminalnych, inaczej w literaturze grozy, inaczej w science fiction. Owe „strategie ontologiczne” mogą być podyktowane również innego rodzaju – niż zróżnicowanie gatunkowe – przyczynami.

In the article I reconstruct Karol Wojtyła’s argument against atheism. According to Wojtyła, an atheist is unjust because of not rendering absolute honour to God. In my opinion the argument is sound if one applies it to theists or negative atheists and if one presupposes that there are moral obligations to only supposed persons. The argument meets some objections. A discussion of them leads me to an interpretation of the theism-atheism controversy as being the conflict of two imperatives: the imperative (...) of justice and the imperative of evidence. (shrink)
