It did so firstly by presenting an analysis of the discussion between Wallace and Kripke, secondly by analysing Tarski’s reasons for introducing satisfaction, and finally by looking at whether Kripke’s definition manages to avoid the issues that motivated Tarski. It concluded that an essential part of the recursive truth-definition given by Kripke is the assumption of a pre-given truth-definition for an atomic language. However, if this atomic language is of infinite size, satisfaction is needed to provide this definition. Rather than differing in whether they make use of satisfaction, this thesis argues that the substitutional and the referential quantifiers differ in where in the definition of truth they make the connection between truth and the world.Show less

This thesis aimed to clarify whether contemporary politics is really post-truth. It did this through an analysis of multiple theories of truth and an overview of the historical origins of post-truth. It concluded that while there are multiple possible substantial theories of truth, all theories of truth have in common the existence of a correctness-notion. Analysis of modern politics shows that correctness-notions are still held by all relevant actors, which entails that they hold at least some theory of truth. Rather than being post-truth, contemporary politics suffers from political communities that have deeply differing worldviews due to lobbying by interest groups, changes to modern media, and post-modernism.Show less

Neuraths beeldtaal en Wittgensteins opvatting van aspectwaarneming impliceren een positieve waardering van het beeld en de perceptie die nodig zijn voor ons begrip van taal. De leidende vraagstelling van dit bachelorwerkstuk is: in hoeverre is Wittgensteins kritiek op het logisch atomisme ook van toepassing op Neuraths beeldtaal? Het werkstuk behandelt de relatie tussen beeld en taal in de filosofie en is een kritische doordenking van Neuraths beeldstatistiek in het licht van Wittgensteins beeldtheorie.Show less

This is notwithstanding the fact that the present-day canonical foundation of mathematics, that is first-order Zermelo-Fraenkel set theory, fails horribly at unambiguous denotation. The aim of the present study is to offer a reasonably self-contained and modern presentation of Zermelo’s theorem that is accessible also to a philosopher with some knowledge of elementary set- and model theory. In a modern framework semi-categoricity cannot be interpreted as a result on first order models. Using full second-order models one salvages external, or ‘true’, semi-categoricity, although one then loses a sound and complete deductive calculus. With Henkin semantics one does have completeness, but retains only internal semi-categoricity.Show less

Brouwer zou hierbij hebben gefungeerd als de voorname inspiratiebron van de latere Wittgenstein. Echter, in deze scriptie wordt aangetoond dat Wittgenstein in de Tractatus Logico-Philosophicus reeds tot de gedachten was gekomen die tot volle bloei kwamen in zijn latere periode; hierbij speelde een bemiddeling van Brouwer geen enkele rol.Show less
