In their paper Nothing but the Truth Andreas Pietz and Umberto Rivieccio present Exactly True Logic, an interesting variation upon the four-valued logic for first-degree entailment FDE that was given by Belnap and Dunn in the 1970s. Pietz & Rivieccio provide this logic with a Hilbert-style axiomatisation and write that finding a nice sequent calculus for the logic will presumably not be easy. But a sequent calculus can be given and in this paper we will show that a calculus for (...) the Belnap-Dunn logic we have defined earlier can in fact be reused for the purpose of characterising ETL, provided a small alteration is made—initial assignments of signs to the sentences of a sequent to be proved must be different from those used for characterising FDE. While Pietz & Rivieccio define ETL on the language of classical propositional logic we also study its consequence relation on an extension of this language that is functionally complete for the underlying four truth values. On this extension the calculus gets a multiple-tree character—two proof trees may be needed to establish one proof. (shrink)

Argues that content-independent reasons are intentions. Relies on Grice's distinction between natural and non-natural meaning. Rejects previous accounts, and argues that his account can understand the force of such reasons appropriately, through the conept of enabling-conditions. Illustrates through several paridigmatic types of content-independent reasons.

RésuméLes modernistes arabes et les humanistes occidentaux considèrent souvent le philosophe musulman Averroès comme l’un des premiers précurseurs de Kant et des Lumières européennes. Contrairement à cette réputation, cet article soutient que ce sont les critiqueurs de Kant, Herder et Tiedemann, qui ont redécouvert Averroès. Tiedemann a été le premier historiographe allemand à donner un compte rendu précis de la pensée d’Averroès. Cela s’est accompagné d’une réévaluation d’Averroès par Herder dans ses Lettres sur les progrès de l’humanité, dans lesquelles il (...) reconnaît la similitude entre son propre concept de l’esprit du temps en tant que raison historique – son alternative au concept des Lumières d’une raison universelle et anhistorique – et le concept d’Averroès d’un intellect matériel unique pour tous les esprits humains individuels. Enfin, l’article expose les liens possibles entre l’interprétation d’Averroès de l’intellect d’Aristote et le concept de raison historique de Hegel. (shrink)

Let us by ‘first-order beliefs’ mean beliefs about the world, such as the belief that it will rain tomorrow, and by ‘second-order beliefs’ let us mean beliefs about the reliability of first-order, belief-forming processes. In formal epistemology, coherence has been studied, with much ingenuity and precision, for sets of first-order beliefs. However, to the best of our knowledge, sets including second-order beliefs have not yet received serious attention in that literature. In informal epistemology, by contrast, sets of the latter kind (...) play an important role in some respectable coherence theories of knowledge and justification. In this paper, we extend the formal treatment of coherence to second-order beliefs. Our main conclusion is that while extending the framework to second-order beliefs sheds doubt on the generality of the notorious impossibility results for coherentism, another problem crops up that might be no less damaging to the coherentist project: facts of coherence turn out to be epistemically accessible only to agents who have a good deal of insight into matters external to their own belief states.

Los descubrimientos de las neurociencias permiten intervenir en el cerebro humano para mejorar su estado o sus capacidades sin indicación médica. Este fenómeno es conocido como “Neuroenhancement” y está sujeto a un amplio debate ético. Como “Neuroenhancement” es un fenómeno evolutivo, el debate de aspectos éticos está necesariamente orientado al futuro y depende de la información sobre el posible desarrollo de la tecnología y sus consecuencias para la sociedad. Sin embargo, hay que establecer límites para la formulación de previsiones especulativas (...) en argumentos éticos y justificaciones políticas. Propongo distinguir argumentos con tres propósitos distintos: la formación de intuiciones éticas, el reflejo sobre el futuro de la sociedad y justificación de normativas y políticas. Para cada uno de ellos necesitamos estándares adecuados. Es tarea de la filosofía política desarrollar un estándar para los argumentos justificadores.: Neuroscientific findings allow interventions in the human brain to improve its function or modify mental states even without medical indication. This procedure, termed as neuroenhancement, is subject to a broad ethical debate. As neuroenhancement is an evolving phenomenon, the debate is necessarily future-oriented and highly dependent on information about future developments. It remains an open question to what degree uncertain forecasting or even speculation should be considered in the ethical debate and policy-making. I propose to distinguish between arguments with three different purposes: intuition-forming, self-reflecting and justifying arguments. Adequate standards are required for all kinds of future-oriented arguments. The development of these standards for justifying arguments is a task for political philosophy. (shrink)

Previous studies suggest in line with dual process models that interoceptive skills affect controlled decisions via automatic or implicit processing. The “framing effect” is considered to capture implicit effects of task-irrelevant emotional stimuli on decision-making. We hypothesized that cardiac awareness, as a measure of interoceptive skills, is positively associated with susceptibility to the framing effect. Forty volunteers performed a risky-choice framing task in which the effect of loss versus gain frames on decisions based on identical information was assessed. The results (...) show a positive association between cardiac awareness and the framing effect, accounting for 24% of the variance in the framing effect. These findings demonstrate that good interoceptive skills are linked to poorer performance in risky choices based on ambivalent information when implicit bias is induced by task-irrelevant emotional information. These findings support a dual process perspective on decision-making and suggest that interoceptive skills mediate effects of implicit bias on decisions. (shrink)

In this thesis the connection between coherence and reliability is investigated. The question may be phrased as follows: does the fact that a set of testimonies is coherent imply that the witnesses who have reported these testimonies are reliable? The same question may also be expressed in terms of beliefs: does the fact that a set of beliefs is coherent imply that the beliefs were reliably produced? Traditionally, coherence theorists have thought that coherence is connected to truth, but in this (...) dissertation the thesis is that it is rather connected to reliability. The investigation proceeds within a probabilistic framework, the so-called witness scenario, where a number of partially reliable witnesses give independent reports. Hence it is primarily coherent sets of testimonies that are discussed, but coherence of beliefs is taken to function similarly, and thus the results acquired using the witness scenario are, it is argued, relevant for the traditional discussion which mostly concerns coherence of beliefs. Using this scenario a notion of reliability-conduciveness, similar to the much-discussed notion of truth-conducivenes, is formally defined. This definition says, roughly, that a measure of coherence C is reliability-conducive if and only if the more coherent a set of testimonies is, as measured by C, the higher is the probability that a witness who has given one of these testimonies is reliable. In Papers I and II it is tested whether a number of coherence measures proposed in the literature are reliability-conducive in various salient scenarios. It is shown that the only coherence measure that is reliability-conducive in all of those scenarios is the so-called Shogenji measure. This observation is then used to argue that the Shogenji measure is a fruitful explication of the notion of coherence. However, in Paper III it is shown that in the most general scenario neither the Shogenji measure nor any other measure of coherence is reliability-conducive. In Paper IV, the use of coherence reasoning in court is investigated. It is shown that we often use the notion of coherence in judicial reasoning, for example to find out whether certain witnesses are reliable or not. Using the results from Papers I and II, as well as additional formal results that strengthen the connection between coherence and reliability, it is argued that this line of reasoning is valid. Also, it is argued in the introductory chapter that these findings show that coherence is indeed closely connected to reliability, even though it is not generally reliability-conducive, and that this connection is much closer than that between coherence and truth. In Paper V, coherent sets of so-called higher order testimonies are examined, where a higher order testimony is defined as a testimony concerning some other witness’s reliability . Such sets have hitherto not been examined within formal coherence theory. It is shown that coherence must be defined in a non-standard way to account for all our intuitions regarding sets involving higher order testimonies. It is then argued that this shows that in order to correctly estimate the degree of coherence of a set of beliefs, the believer must have a firm grasp of her own reliability; a fact that in turn is taken to be problematic for the coherence theory of justification.

The concept of event is one of the key notions of many theories dealing with causality or agency. In this paper we study different approaches to events that share the basic assumption that events can be analyzed fruitfully in branching-time structures. The terminological framework developed thereby may be helpful for further analyses in the fields of causality and agency and also in those fields of computational semantics, where similar concepts are considered.

Two questions are the starting point for the discussion contained in this article: (a) Does the future exist? (b) What is the future? A preliminary analysis of these questions leads to the conclusion that their solution needs to introduce three different principal modes of existence characterized for objects belonging to the time sphere of being. They are: real (actual) existence (i.e. existence of „now”), postreal existence (the past) and potential (prereal) existence. In accordance with this differentiation the answer to point (...) (a) is generally determined by the following theses: (1) The future exists in potentiality, (2) The future exists neither in reality nor in postreality. The notion of potential existence includes two categories of objects. The first one - objects which in fact will become real objects (present). They may be described as potential objects sensu stricto. The second category constists of the quasi-potential objects, that is the objects whose potentiality of becoming real (actual) ones will never come into existence. The differentiation of categories mentioned above makes possible to formulate three definitions of the future: (D1) The future is the domain of potential, or quasi-potential objects, (D2) The future is the domain of the potential objects, (D3) The future is the domain of quasi-potential objects. The definition (D3) is obviously inadequate, hence the solution of the problem, what is the future, may be reduced to the choice between definitions (D1) and (D2). The arguments of the paper convince us that the adequate definition of the future is the definition (D2). First - contrary to (D1) - it describes the future as ontologically homogeneous domain containing only objects which will become objects of the present and subsequently past objects. Second, when the future is defined by the competitive definition (D1) it is doubtful whether the language systems, referring to the time sphere of being, can fulfill the basic principles of the classical logig: the principle of contradiction and the principle of excluded middle.

In this article, I wish to show that Kaufmann was right, when he claimed that “nobody has ever found a better characterization of Nietzsche” than his own, when he talked about the “music-making Socrates” in the Birth of Tragedy. Firstly, I make some general remarks on the Birth of Tragedy. Secondly, I analyse Nietzsche’s understanding of music in the Birth of Tragedy. Thirdly, I describe the particular conception of “Socrates” as Nietzsche develops it in The Birth of Tragedy. Lastly, I (...) bring these two concepts together, showing that there are various parts of Nietzsche’s mature philosophy which demonstrate a correspondence between the qualities of the “music making Socrates” and the qualities of the later Nietzsche. In this way, I establish that the later Nietzsche is very similar to the “music-making Socrates”, whom he mentioned in his Birth of Tragedy. (shrink)

It is not uncommon to hear parents say in discussions they have with their children ‘Look at it this way’. And called upon for their advice, counsellors too say something to adults with the significance of ‘Try to see it like this’. The change of someone's perspective in the context of child rearing is the focus of this paper. Our interest in this lies not so much in giving an answer to the practical problems that are at stake, but at (...) disentangling the issues on a conceptual level. Within the so‐called second part of his Philosophical Investigations, Wittgenstein deals with shared practices and with concepts such as ‘seeing’ and ‘seeing as’. What he says there is in terms of content linked with his earlier Tractatus position concerning ethics, a matter which will first be dealt with. After that, the relevant sections of his later work are discussed. Following Cavell, it is concluded that to try to get someone to see what one sees, necessarily presupposes giving it out of one's hands. The passivity this points at highlights what Erziehung in the end comes down to. (shrink)

Some contemporary readings of Averroes put special emphasis on the philosophical and critical character of the work of the Muslim theologian and mystic al-Ġazālī, who is also known as the “Proof of Islam”. They even regard him as some pioneer of Enlightenment thought. This paper therefore investigates the thesis of Averroes as a critical philosopher. It sets forth that one can indeed find some essential elements of critical thought in al-Ġazālī’s writings: for example Ġazālī’s critique of reason and especially his (...) rejection of, which means the nonreflective imitation of a teacher, authority or tradition, especially in matters pertaining to religion. Nevertheless, comparing him to both, Kant and Descartes, we will try to show that his thought falls short of critical thinking and even of philosophy itself. To this end we will proceed as follows: First, we analyze his critique of taqlīd. Secondly, we investigate his critique of Aristotelian Arabic philosophy as a variety of taqlīd. Thirdly, we consider his skeptical suspension of reason in favor of immediate prophetic perception. Fourthly, we look upon the relationship between the super-rational perception and reason. Fifthly, we show that Ġazālī dismisses the idea of autonomous reason. (shrink)

It is one of the crucial insights of pragmatism that our judging is itself a discursive practice. Our judgments are normatively determined performances for which we are responsible. Therefore, judgments are a species of action. For in both actions and judgments, we subject ourselves and others to justifiable norms. Since these insights can already be found in Hegel, Hegel is now often interpreted as a champion of pragmatism. Hegel’s logic is thereby mainly understood as the continuation of the Kantian project (...) of transcendental philosophy. Based upon this pragmatist interpretation of Hegel, the paper reads F. H. Jacobi’s philosophy as an alternative pragmatism which is explicitly founded on our life praxis rather than our practice of judgment. (shrink)

A central and fundamental problem in moral philosophy is that of understanding how moral principles and theories can be justified. It involves finding rational solutions to both theoretical problems and to substantial moral questions . According to Moral Intuitionism, some normative judgments, usually called moral intuitions, justify moral principles and theories. Typically, moral intuitionists promise a method that is supposed to yield progress toward finding the answers to ethical disputes and controversies. ;I argue, first, that all versions of moral intuitionism (...) must assume that there are moral facts and that moral judgments are descriptions of these facts. Next, I consider whether these assumptions are defensible. I focus on an argument based on a claim that we have no reason to believe that any moral facts exist, because no such facts need to be postulated in our best explanations of anything. I analyze several recent replies to this line of attack, and I argue that none meets the challenge. ;Finally, I propose a reply which seems to meet a number of relevant theoretical requirements: it allows us to say that some moral judgments are true because they correspond to facts, and those judgments are sometimes justified. I argue, however, that even this version of moral realism has serious flaws. It implies that the content of moral language is community relative. That is, such sentences as 'Jews ought to be exterminated' have to be treated as ambiguous, expressing several different propositions, some true and some false. In consequence, when a Nazi issues such a judgment, he may be making a claim that is neither false nor unjustified. ;I conclude that Moral Intuitionism does not help to reach rational solutions to moral disputes and disagreements. Therefore, this view should be rejected, and we should look elsewhere for a method that would solve both theoretical and substantial problems of justification in ethics. (shrink)
