Dieses Lehrbuch vermittelt eines der wichtigsten Werkzeuge der Philosophie durch die Einführung in die Grundideen einer formalen Sprache. Schrittweise werden so die relevanten Sprachstrukturen aufgedeckt, die dann in der Aussagen- und Prädikatenlogik formalisiert werden. Sowohl die Semantik als auch ein Kalkül des natürlichen Schließens werden jeweils detailliert diskutiert. In Kombination mit einer Lernplattform wird der zentrale Stoff anwendungsorientiert und plastisch vermittelt, was die auch zum Selbststudium geeignete Einführung zum idealen Begleiter für das Philosophiestudium macht.

In this paper, I argue for two claims, that on a common conception of the second order property of being a mental disorder, some facts about mental disorders are the result of social constructions, and that the way facts about mental disorders are constructed differs from the received view on social construction. The difference is examined, a novel type of social construction is identified, and it is suggested that there are numerous other types of social facts that are constructed in a similar way.

Recently, a time-honored assumption has resurfaced in some parts of the free will debate: if past divine beliefs or past truths about what we do depend on what we do, then these beliefs and truths are, in a sense, up to us; hence, we are able to act otherwise, despite the existence of past truths or past divine beliefs about our future actions. In this paper, I introduce and discuss a novel incompatibilist argument that rests on. This argument is interesting in itself, for it is independent of a number of assumptions about the nature of God that have played an essential role in the classical defense of incompatibilism about divine foreknowledge and human free will. Moreover, the argument enables us to identify a difficulty compatibilists encounter when employing to block incompatibilism.

As one of the world's most eminent living philosophers, John Perry has covered a remarkable breadth of subjects in his published work, including semantics, indexicality, self-knowledge, personal identity, and consciousness. Looking particularly at the way in which he deals with issues of self, communication, and reality, this volume is organized in seven chapters that highlight a different aspect of Perry's work on the intersection of these subjects. A fundamental work for students and scholars, Identity, Language, and Mind explores questions that are not only essential in understanding Perry's writings, but also contemporary philosophy as a whole.

This volume investigates the notion of reduction. Building on the idea that philosophers employ the term ‘reduction’ to reconcile diversity and directionality with unity, without relying on elimination, the book offers a powerful explication of an “ontological” notion of reduction the extension of which is (primarily) formed by properties, kinds, individuals, or processes. It argues that related notions of reduction, such as theory-reduction and functional reduction, should be defined in terms of this explication. Thereby, the book offers a coherent framework, which sheds light on the history of the various reduction debates in the philosophy of science and in the philosophy of mind, and on related topics such as reduction and unification, the notion of a scientific level, and physicalism.

Criticizing Gallagher’s view on direct perception, I develop a basic model of social perception. According to the Cartesians another person’s intentions are not directly accessible to an observer. According to the cognitivist Cartesians conscious processes are necessary for social understanding. According to the Anti-Cartesians social perception is direct. Since both of these latter approaches face serious problems, I will argue in favor of an alternative: anti-cognitivist Cartesianism. Distinguishing between an active- and a passive part of the perceptual system we can describe the situation as follows: Some functionally individuated parts of our nervous system generate percepts that correspond to the properties that causally trigger the system, whilst others form percepts of properties that do not causally trigger the system. The model is basic in that it merely helps clarifying some of the fundamental concepts we need in order to describe empirical findings

Among philosophers of mind, it is common to assume that at least some mental properties are functional in nature, and that functional properties are second-order properties. In the functionalist literature, the notion of being a second-order property is cashed out in three different ways: (i) in terms of semantic features of characterizations or definitions of properties, (ii) in terms of syntactic features of second-order quantification, and (iii) in terms of a metaphysical criterion, according to which properties are second order if they are properties of first-order properties. It is shown that in the context of functionalism reference to these interpretations is misguided, and it is suggested that the notion of an ordering of properties in this context is best understood as being tied to dependence-relations

Assume that water reduces to H2O. If so water is identical to H2O. At the same time, if water reduces to H2O then H2O does not reduce to water–the reduction relation is asymmetric. This generates a puzzle–if water just is H2O it is hard to see how we can account for the asymmetry of the reduction relation. The paper proposes a solution to this puzzle. It is argued that the reduction predicate generates intensional contexts and that in order to account for the asymmetry, we should develop conditions on the meanings of expressions that flank the reduction predicate in true reduction statements. Finally, it is argued that if we adopt this interpretation, we can illuminate the epistemological difference between reduced and reducing item commonly referred to in the literature

The paper offers an account of the structure of information provided by models that relevantly deviate from reality. It is argued that accounts of scientific modeling according to which a model’s epistemic and pragmatic relevance stems from the alleged fact that models give access to possibilities fail. First, it seems that there are models that do not give access to possibilities, for what they describe is impossible. Secondly, it appears that having access to a possibility is epistemically and pragmatically idle. Based on these observations, an alternative is developed

Nagel’s official model of theory-reduction and the way it is represented in the literature are shown to be incompatible with the careful remarks on the notion of reduction Nagel gave while developing his model. Based on these remarks, an alternative model is outlined which does not face some of the problems the official model faces. Taking the context in which Nagel developed his model into account, it is shown that the way Nagel shaped his model and, thus, its well-known deficiencies, are best conceived of as a mere by-product of his philosophical background.

In this paper I discuss an important aspect of David Chalmers' interpretation of two-dimensional semantics. I will argue that his approach cannot be used to model something like Fregean sense: Semantic concepts similar to the notion of a sense do not, unlike the notion of an epistemic intension, depend on epistemological notions like apriority or acceptability on purely rational grounds. This conceptual difference gives rise to the problem that primary intensions cannot do the work Fregean senses were designed for: They cannot, contrary to what Chalmers suggests, explain cognitive role. © 2012 Elsevier B.V., All rights reserved.

In this paper, a cognate of the problem of divine foreknowledge is introduced: the problem of the prophet’s foreknowledge. The latter cannot be solved referring to Ockhamism—the doctrine that divine foreknowledge could, at least in principle, be compatible with human freedom because God’s beliefs about future actions are merely soft facts, rather than hard facts about the past. Under the assumption that if Ockhamism can solve the problem of divine foreknowledge then it should also yield a solution to the problem of the prophet’s foreknowledge, it is concluded that Ockhamism fails
