Stig Kanger made important contributions to logic and formal philosophy. Kanger's dissertation Provability in Logic, 1957, contained significant results in proof theory as well as the first fully worked out model-theoretic interpretation of quantified modal logic. It is generally accepted nowadays that Kanger was one of the originators of possible worlds semantics for modal logic. Kanger's most original achievements were in the areas of general proof theory, the semantics of modal and deontic logic, and the logical analysis of the (...) concept of rights. He also contributed to action theory, preference logic, and the theory of measurement. This is the first of two volumes dedicated to the work of Stig Kanger. The present volume is a complete collection of Kanger's philosophical papers. The second volume contains critical essays on Kanger's work, as well as biographical essays on Kanger written by colleagues and friends. (shrink)

This article studies the Islamic State's only remaining periodical, Al-Naba, identifying the most common tropes and patterns in the periodical's Sub-Saharan Africa coverage, and on Mozambique in particular. The Islamic State's increasingly important coverage of Africa focuses on terror attacks, military campaigns and on the fight against Christianity. However, it also employs more traditional anti-colonial arguments that have been used by other, more accepted, political actors during the struggle for decolonisation. Al-Naba also functions as a 'shamer' of non-African Muslims, to (...) get them to join jihad by pointing to the African successes of the organisation and set these successes up as examples to be followed. In this sense, the article illustrates how African jihadist branches can have global agency. (shrink)

This book explores two questions that are integral to the question of the existence of God. The first question concerns the meaning of "existence" and the second concerns the meaning of "God". Regarding the first question, this book motivates, presents and defends the meta-ontology found in Gottlob Frege's writings and defended by Michael Dummett, Crispin Wright and Bob Hale. Frege's approach to questions of existence has mainly found use in connection with abstract objects such as numbers. This is one of (...) the first studies to systematically present Fregean meta-ontology and apply it to theology. Frege's meta-ontology is informed by his context principle. According to this, logico-syntactic notions such as "singular term" and "predicate" are pivotal to questions of what exists. These notions serve to throw light on the second question. Through thorough engagement with Old as well and New Testament texts, the book shows how Frege's logico-syntactic notions are of crucial importance when seeking to understand the meaning and use of "God". To complete the defence of Fregean meta-ontology, the book concludes by pointing to important differences between the otherwise closely associated concepts of an object found in Wittgenstein's Tractatus Logico-Philosophicus and Frege's writings.

In the work of both Ludwik Fleck and Thomas Kuhn the scientific literature plays important roles for stability and change of scientific phenomenal worlds. In this article we shall introduce the analyses of scientific literature provided by Fleck and Kuhn, respectively. From this background we shall discuss the problem of how divergent thinking can emerge in a dogmatic atmosphere. We shall argue that in their accounts of the factors inducing changes of scientific phenomenal worlds Fleck and Kuhn offer substantially different (...) approaches, and we shall discuss in which respects their approaches may be compatible.

Technology is increasingly subject of attention from philosophers. Philosophical reflection on technology exhibits a wide and at times bewildering array of approaches and modes of thought. This volume brings to light the development of three schools in the philosophy of technology. Based on thorough introductions to Karl Marx', Martin Heidegger's and John Dewey's thought about technology, the volume offers an in-depth account of the way thinkers in the critical, the phenomenological and the pragmatic schools have respond to issues and challenges (...) raised by the works of the founders of these schools. Technologies in almost any aspect of human life is potentially subject of philosophical treatment. To offer a focused demonstration of key arguments and insights, the presentation of each school is concluded with a contribution to discussions of educational technologies. In addition to philosophers seeking a valuable and clear structuring of a still burgeoning field, the volume is of interest to those working with educational philosophy and value sensitive design. „Stig Børsen Hansen’s book is a must for all interested in understanding the development of the philosophy of technology and the relation of thoughts of thinkers that have shaped the area. The author presents a new and refreshing take on the ideas from Marx to Marcuse, from Dewey to Latour, and Heidegger to Borgmann. It will engage and hopefully provoke." Dr. Jan Kyrre Berg Friis, University of Copenhagen. (shrink)

`Proto-idea' was a central concept in the thinking of the Polish microbiologist and philosopher of science Ludwik Fleck (1896–1961). Based on studies of the origin of the modern concept of syphilis, Fleck claimed that many established scientific facts are best understood as interpretations of pre scientific, somewhat hazy `proto-ideas' in the framework of a certain `thought-style'. As an example,Fleck saw the modern knowledge of infection as an interpretation of the ancient proto-idea of diseases as caused by minute `animalcules'. However, the (...) epistemological aspects of the concept of proto-ideas have only been sparsely developed and discussed by Fleck and his critics. This paper attempts to bridge the gap. Firstly, I reconstruct the concept of proto-ideasin the context of Fleck's constructivist theory of knowledge. Secondly, I illustrate the relation between Fleck's concept of proto-ideas and his nominalist view on medical taxonomy. Finally, I discuss four philosophical problems implied by Fleck's concept of proto-ideas: (a) the problem of combining two conflicting perspectives on the history of science (b) the problem of accounting for the notion of` continuity' within a non realist theory of knowledge (c) the problem of ascribing no truth-content to proto-ideas, and (d) the problem concerning the non-neutrality of the analyst's viewpoint.

In "representing and intervening", Ian hacking argues that on a fregean semantics of scientific theory, Incommensurability between competing theories threatens, In the strong sense of precluding their being about the same entities; whereas no such threat arises on putnam's account. On fregean principles, Hacking's argument would however at best support a much weaker claim. In any case, The pivot of his argument is the completely unfounded assumption that the fregean is commited to semantical holism.

It is argued that C. Wright's worry over the Basic Argument for Quitism is misplaced since the argument is incoherent. An even more basic argument is considered, and some consequences traced for, inter alia, the Tractarian view in metaphysics and Dummett's Metaphor Thesis, connecting ontology and semantics. In the course of the argument, work by, primarily, C. Peacocke and J. McDowell is touched upon.
