  1. Region-based topology.Peter Roeper - 1997 - Journal of Philosophical Logic 26 (3):251-309.
    A topological description of space is given, based on the relation of connection among regions and the property of being limited. A minimal set of 10 constraints is shown to permit definitions of points and of open and closed sets of points and to be characteristic of locally compact T2 spaces. The effect of adding further constraints is investigated, especially those that characterise continua. Finally, the properties of mappings in region-based topology are studied. Not all such mappings correspond to point (...)

  • Ethik und Moral im Wiener Kreis. Zur Geschichte eines engagierten Humanismus.Anne Siegetsleitner - 2014 - Wien: Böhlau.
    Die vorliegende Schrift unternimmt eine Revision des vorherrschenden Bildes der Rolle und der Konzeptionen von Moral und Ethik im Wiener Kreis. Dieses Bild wird als zu einseitig und undifferenziert zurückgewiesen. Die Ansicht, die Mitglieder des Wiener Kreises hätten kein Interesse an Moral und Ethik gezeigt, wird widerlegt. Viele Mitglieder waren nicht nur moralisch und politisch interessiert, sondern auch engagiert. Des Weiteren vertraten nicht alle die Standardauffassung logisch-empiristischer Ethik, die neben der Anerkennung deskriptiv-empirischer Untersuchungen durch die Ablehnung jeglicher normativer und inhaltlicher (...)

  • Arithmetic and geometry: Some remarks on the concept of complementarity.M. Otte - 1990 - Studies in Philosophy and Education 10 (1):37-62.
    This paper explores the classical idea of complementarity in mathematics concerning the relationship of intuition and axiomatic proof. Section I illustrates the basic concepts of the paper, while Section II presents opposing accounts of intuitionist and axiomatic approaches to mathematics. Section III analyzes one of Einstein's lecture on the topic and Section IV examines an application of the issues in mathematics and science education. Section V discusses the idea of complementarity by examining one of Zeno's paradoxes. This is followed by (...)

  • A new symbolic representation of the basic truth-functions of the propositional calculus.Jerome Frazee - 1988 - History and Philosophy of Logic 9 (1):87-91.
    As with mathematics, logic is easier to do if its symbols and their rules are better. In a graphic way, the logic symbols introduced in thís paper show their truth-table values, their composite truth-functions, and how to say them as either ?or? or ?if ? then? propositions. Simple rules make the converse, add or remove negations, and resolve propositions.

  • A new symbolic representation for the algebra of sets.Jerome Frazee - 1990 - History and Philosophy of Logic 11 (1):67-75.
    The algebra of sets has, basically, two different types of symbols. One type of symbol (∩, ?, +, ?) defines another set from two other sets. A second type of symbol (?, ?, =, ?) makes a proposition about two sets. When the construction of these two types of symbols is based on the same four-dot matrix as the logic symbols described in a previous paper, the three symbol types then dovetail together into a harmonious whole that greatly simplifies derivation (...)

  • The Paradoxes of Deontic Logic: Alive and Kicking.Jörg Hansen - 2006 - Theoria 72 (3):221-232.
    In a recent paper, Sven Danielsson argued that the ‘original paradoxes' of deontic logic, in particular Ross's paradox and Prior's paradox of derived obligation, can be solved by restricting the modal inheritance rule. I argue that this does not solve the paradoxes.
