    Branching Time, Indeterminism and Tense Logic.Thomas Ploug & Peter Øhrstrøm - 2012 - Synthese 188 (3):367-379.
    This paper deals with the historical and philosophical background of the introduction of the notion of branching time in philosophical logic as it is revealed in the hitherto unpublished mail-correspondence between Saul Kripke and A.N. Prior in the late 1950s. The paper reveals that the idea was first suggested by Saul Kripke in a letter to A.N. Prior, dated September 3, 1958, and it is shown how the elaboration of the idea in the course of the correspondence was intimately intervowen (...)

    The Prior-von Wright Debate on Anselm's Argument for the Existence of God.David Jakobsen & Peter Øhrstrøm - 2017 - In Ilkka Niiniluoto & Thomas Wallgren (eds.), On the Human Condition : Philosophical Essays in Honour of the Centennial Anniversary of Georg Henrik von Wright. Helsingfors, Finland: pp. 255-267.
    Arthur Norman Prior (1914 – 1969) and Georg Henrik von Wright (1916 – 2003) both attended a conference in England sometime in the spring of 1956, after which they corresponded on Anselm’s ontological argument. Prior had at the conference presented a formal treatment of the ontological argument. Based upon notes from the Prior archive at the Bodleian Library, and correspondence with von Wright, we here presents Prior’s and von Wrights’ discussion of Anselm’s argument in light of Prior’s published, as well (...)

    A Critical Discussion of Prior’s Philosophical and Tense-Logical Analysis of the Ideas of Indeterminism and Human Freedom.Peter Øhrstrøm - 2019 - Synthese 196 (1):69-85.
    This paper is a critical discussion of A.N. Prior’s contribution to the modern understanding of indeterminism and human freedom of choice. Prior suggested that these ideas should be conceived in terms of his tense logic. It can be demonstrated that his approach provides an attractive formalization that makes it possible to discuss indeterminism and human freedom of choice in a very precise manner and in a broader metaphysical context. It is also argued that Prior’s development of this approach was closely (...)

    Prior’s Paradigm for the Study of Time and its Methodological Motivation.Per Hasle & Peter Øhrstrøm - 2016 - Synthese 193 (11):3401-3416.
    A. N. Prior’s writings should obviously be studied already for historical reasons. His inventions of modern temporal logic and hybrid logic are clearly important events in the history of logic. But the enduring importance of studying his works also rests on his methodological approach, which remains highly relevant also for systematical reasons. In this paper we argue that Prior’s formulation in the 1950s of a tense-logical paradigm for the study of time should be understood in the light of at least (...)

    Prior's Defence of Hintikka's Theorem. A Discussion of Prior's 'The Logic of Obligation and the Obligations of the Logician'.Peter Øhrstrøm, Jörg Zeller & Ulrik Sandborg-Petersen - 2012 - Synthese 188 (3):449-454.
    In his paper, The logic of obligation and the obligations of the logician, A.N. Prior considers Hintikka's theorem, according to which a statement cannot be both impossible and permissible. This theorem has been seen as problematic for the very idea of a logic of obligation. However, Prior rejects the view that the logic of obligation cannot be formalised. He sees this resistance against such a view as an important part of what could be called the obligation of the logician. Prior (...)

    Geochronology as a Metaphysical Research Programme.Peter Øhrstrøm - 1987 - Zeitschrift Für Allgemeine Wissenschaftstheorie 18 (1-2):204-214.
    In diesem Artikel wird der wissenschaftstheoretische Stand der Geochronologie mit Hintergrund in den Arbeiten von Kuhn und besonders Popper diskutiert. Die Geochronologie wird untersucht mit Hinblick auf generelle methodologische Voraussetzungen, Terminologie, normal-wissenschaftliche Aktivitätsform und "theoretische Dogmatik". Als Konklusion ergibt sich, daß die fundamentalen Theoriekonstruktionen der Geochronologie nicht testbar sind, sondern als ein metaphysisches Forschungsprogramm im Sinne Poppers charakterisiert werden müssen.

    Ethical Problems Inherent in Psychological Research Based on Internet Communication as Stored Information.Peter Øhrstrøm & Johan Dyhrberg - 2007 - Theoretical Medicine and Bioethics 28 (3):221-241.
    This paper deals with certain ethical problems inherent in psychological research based on internet communication as stored information. Section 1 contains an analysis of research on Internet debates. In particular, it takes into account a famous example of deception for psychology research purposes. In section 2, the focus is on research on personal data in texts published on the Internet. Section 3 includes an attempt to formulate some ethical principles and guidelines, which should be regarded as fundamental in research on (...)

    Peircean Diagrams of Time.Peter Øhrstrøm - 2011 - Semiotica 2011 (186):259-274.
    Some very good arguments can be given in favor of the Augustinean wisdom, according to which it is impossible to provide a satisfactory definition of the concept of time. However, even in the absence of a proper definition, it is possible to deal with conceptual problems regarding time. It can be done in terms of analogies and metaphors. In particular, it is attractive to make use of Peirce's diagrams by means of which various kinds of conceptual experimentation can be carried (...)

    Prior's Grappling with Peirce's Existential Graphs.Peter Øhrstrøm - 2018 - History and Philosophy of Logic 39 (2):158-163.
    A. N. Prior very much admired the logic and philosophy of C.S. Peirce. In the spring of 1962 Prior went to Chicago to study Peirce's ideas. One of the topics that caught his attention was Peirce's existential graphs. This interest continued when he returned to England. In this paper Prior's grappling with the existential graphs will be discussed.

    Conceptual and Metaphysical Origins and Relevance of Temporal Logic.David Jakobsen & Peter Øhrstrøm - unknown
    Logic has sometimes been seen as an alternative to metaphysics and to speculation. In this paper it is argued that a different story should be told when it comes to temporal logic and tense-logic in particular. A.N. Prior’s first formulation of tense logic was mainly established in order to qualify the discussion of certain metaphysical and conceptual problems. Although temporal logic has now been developed in various abstract and rather technical ways, it may still serve as a great help for (...)

    Conventionality in Distant Simultaneity.Peter Øhrstrøm - 1980 - Foundations of Physics 10 (3-4):333-343.
    The paper defends the thesis of conventionality in distant simultaneity within the special theory of relativity. The thesis can be expressed in the following way: There is no method independent of standard synchronization by which the one-way velocity of light can be measured if all empirical consequences of the special theory of relativity are to be accepted. Three methods which have recently been suggested are investigated. It is shown that they all depend on the method of standard synchronization. It is (...)

    Darwin's Perplexing Paradox: Intelligent Design in Nature.Steinar Thorvaldsen & Peter Øhrstrøm - 2013 - Perspectives in Biology and Medicine 56 (1):78-98.
    Much has been written through the years of the clash between Darwinism and natural theology, and the basic tenants of this debate are well understood (Gillispie 1959; Bowler 1977; Ruse 2003; McGrath 2011). However, the literature is still growing, and one may wonder if anything new may yet be added. Of these new literary sources, one of the richest is the online Darwin Correspondence Project, which makes it possible to search and read the full texts of all correspondence either sent (...)
