    Explanatory Conditionals.Holger Andreas - forthcoming - Philosophy of Science.
    The present paper aims to complement causal model approaches to causal explanation by Woodward [15], Halpern and Pearl [5], and Strevens [14]. It centres on a strengthened Ramsey Test of conditionals: α ≫ γ iff, after sus- pending judgment about α and γ, an agent can infer γ from the supposition of α. It has been shown by Andreas and Gu ̈nther [1] that such a conditional can be used as starting point of an analysis of ‘because’ in natural language. (...)

    A Ramsey Test Analysis of Causation for Causal Models.Holger Andreas & Mario Günther - forthcoming - British Journal for the Philosophy of Science.
    We aim to devise a Ramsey test analysis of actual causation. Our method is to define a strengthened Ramsey test for causal models. Unlike the accounts of Halpern and Pearl ([2005]) and Halpern ([2015]), the resulting analysis deals satisfactorily with both over- determination and conjunctive scenarios.

    Causation in Terms of Production.Holger Andreas & Mario Günther - forthcoming - Philosophical Studies:1-27.
    In this paper, we analyse actual causation in terms of production. The latter concept is made precise by a strengthened Ramsey Test semantics of conditionals: \ iff, after suspending judgement about A and C, C is believed in the course of assuming A. This test allows us to verify or falsify that an event brings about another event. Complementing the concept of production by a weak condition of difference-making gives rise to a full-fledged analysis of causation.

    A Modal View of the Semantics of Theoretical Sentences.Holger Andreas - 2010 - Synthese 174 (3):367 - 383.
    Modal logic has been applied in many different areas, as reasoning about time, knowledge and belief, necessity and possibility, to mention only some examples. In the present paper, an attempt is made to use modal logic to account for the semantics of theoretical sentences in scientific language. Theoretical sentences have been studied extensively since the work of Ramsey and Carnap. The present attempt at a modal analysis is motivated by there being several intended interpretations of the theoretical terms once these (...)

    On the Ramsey Test Analysis of ‘Because’.Holger Andreas & Mario Günther - forthcoming - Erkenntnis:1-34.
    The well-known formal semantics of conditionals due to Stalnaker Studies in logical theory, Blackwell, Oxford, 1968), Lewis, and Gärdenfors The logic and 1140 epistemology of scientific change, North-Holland, Amsterdam, 1978, Knowledge in flux, MIT Press, Cambridge, 1988) all fail to distinguish between trivially and nontrivially true indicative conditionals. This problem has been addressed by Rott :345–370, 1986) in terms of a strengthened Ramsey Test. In this paper, we refine Rott’s strengthened Ramsey Test and the corresponding analysis of explanatory relations. We (...)

    Carnaps Wissenschaftslogik: Eine Untersuchung Zur Zweistufenkonzeption.Holger Andreas - 2007 - Mentis.
    Als Wissenschaftslogik bezeichnet Carnap jene Disziplin, welche die Nachfolge der traditionellen Philosophie im 20. Jahrhundert antreten sollte. Den zentralen Bezugspunkt von Carnaps wissenschaftslogischen Arbeiten bildet die von Frege und Russell entwickelte mathematische Logik. Dies gilt auch für die Zweistufenkonzeption, mit der Carnap ein allgemeines Schema zur Analyse der Bedeutung von Begriffen nichtmathematischer Theorien entwirft. Dabei wird die Abhängigkeit der begrifflichen Bedeutung von den Aussagen der jeweiligen Theorie explizit anerkannt, was eine Überwindung der Dogmen des Empirismus innerhalb des Logischen Empirismus einschlieβt.

    Theoretical Terms in Science.Holger Andreas - forthcoming - Stanford Encyclopedia.
    A simple explanation of theoreticity says that a term is theoretical if and only if it refers to nonobservational entities. Paradigmatic examples of such entities are electrons, neutrinos, gravitational forces, genes etc. There is yet another explanation of theoreticity: a theoretical term is one whose meaning becomes determined through the axioms of a scientific theory. The meaning of the term ‘force’, for example, is seen to be determined by Newton’s laws of motion and further laws about special forces, such as (...)

    New Account of Empirical Claims in Structuralism.Holger Andreas - 2010 - Synthese 176 (3):311 - 332.
    In this paper, a new account of empirical claims in structuralism is developed. Its novelty derives from the use that is made of the linguistic approach to scientific theories despite the presumed incompatibility of structuralism with that approach. It is shown how the linguistic approach can be applied to the framework of structuralism if the semantic foundations of that approach are refined to do justice to the doctrine of indirect interpretation of theoretical terms. This doctrine goes back to Carnap but (...)

    A Structuralist Theory of Belief Revision.Holger Andreas - 2011 - Journal of Logic, Language and Information 20 (2):205-232.
    The present paper aims at a synthesis of belief revision theory with the Sneed formalism known as the structuralist theory of science. This synthesis is brought about by a dynamisation of classical structuralism, with an abductive inference rule and base generated revisions in the style of Rott (2001). The formalism of prioritised default logic (PDL) serves as the medium of the synthesis. Why seek to integrate the Sneed formalism into belief revision theory? With the hybrid system of the present investigation, (...)

    Another Solution to the Problem of Theoretical Terms.Holger Andreas - 2008 - Erkenntnis 69 (3):315-333.
    In this paper, a solution to the problem of theoretical terms is developed that is based on Carnap’s doctrine of indirect interpretation of theoretical terms. This doctrine will be given a semantic, model-theoretic explanation that is not given by Carnap himself as he remains content with a syntactic explanation. From that semantic explanation, rules for the truth-value assignment to postulates, i.e. sentences that determine the meaning of theoretical terms, are derived. The logical status of postulates will be clarified thereby in (...)

    Basic Concepts of Structuralism.Holger Andreas & Frank Zenker - 2014 - Erkenntnis 79 (S8):1367-1372.
    Primarily addressed to readers unfamiliar with the structuralist approach in philosophy of science, we introduce the basic concepts that the contributions to this special issue presuppose. By means of examples, we briefly review set-theoretic structures and predicates, the potential and actual models of an empirical theory, intended applications, as well as links and specializations that are applied, among others, in reconstructing the empirical claim associated with a theory element.

  12. Semantic Holism in Scientific Language.Holger Andreas - 2010 - Philosophy of Science 77 (4):524-543.
    Whether meaning is compositional has been a major issue in linguistics and formal philosophy of language for the last 2 decades. Semantic holism is widely and plausibly considered as an objection to the principle of semantic compositionality therein. It comes as a surprise that the holistic peculiarities of scientific language have been rarely addressed in formal accounts so far, given that semantic holism has its roots in the philosophy of science. For this reason, a model-theoretic approach to semantic holism in (...)

    Deductive Reasoning in the Structuralist Approach.Holger Andreas - 2013 - Studia Logica 101 (5):1093-1113.
    The distinction between the syntactic and the semantic approach to scientific theories emerged in formal philosophy of science. The semantic approach is commonly considered more advanced and more successful than the syntactic one, but the transition from the one approach to the other was not brought about without any loss. In essence, it is the formal analysis of atomic propositions and the analysis of deductive reasoning that dropped out of consideration in at least some of the elaborated versions of the (...)

    On Choice of Time Metric. What criteria ought to be satisfied by those observable processes which, accompanied by a function assigning values to intervals of that processes, serve as the standard for measurement of time? In how far do the criteria which can reasonably be established admit of an unambigous definition of time metric? That are the questions to which I have addressed myself in the paper. Peter Janich has aimed at solving the problem with careful avoidance of any reference (...)

    A Finite Memory Argument for an Axiomatic Conception of Scientific Theories.Holger Andreas - 2015 - International Studies in the Philosophy of Science 29 (2):113-127.
    This article concerns the split between syntactic and semantic approaches to scientific theories. It aims at showing that an axiomatic representation of a scientific theory is a precondition of comprehending if the models of contain infinite entities. This result is established on the basis of the proposition that the human mind—which is finitely bounded for all we know—is not capable of directly grasping infinite entities. In view of this cognitive limitation, an indirect and finite representation of possibly infinite components of (...)

    Modular Semantics for Theories: An Approach to Paraconsistent Reasoning.Holger Andreas - 2018 - Journal of Philosophical Logic 47 (5):877-912.
    Some scientific theories are inconsistent, yet non-trivial and meaningful. How is that possible? The present paper aims to show that we can analyse the inferential use of such theories in terms of consistent compositions of the applications of universal axioms. This technique will be represented by a preferred models semantics, which allows us to accept the instances of universal axioms selectively. For such a semantics to be developed, the framework of partial structures by da Costa and French will be extended (...)

    Ontological Aspects of Measurement.Holger Andreas - 2008 - Axiomathes 18 (3):379-394.
    The concept of measurement is fundamental to a whole range of different disciplines, including not only the natural and engineering sciences, but also laboratory medicine and certain branches of the social sciences. This being the case, the concept of measurement has a particular relevance to the development of top-level ontologies in the area of knowledge engineering. For this reason, the present paper is concerned with ontological aspects of measurement. We are searching for a list of concepts that are apt to (...)

    Carnapian Structuralism.Holger Andreas - 2014 - Erkenntnis 79 (S8):1373-1391.
    This paper aims to set forth Carnapian structuralism, i.e., a syntactic view of the structuralist approach which is deeply inspired by Carnap’s dual level conception of scientific theories. At its core is the axiomatisation of a metatheoretical concept AE(T) which characterises those extensions of an intended application that are admissible in the sense of being models of the theory-element T and that satisfy all links, constraints and specialisations. The union of axiom systems of AE(T) (where T is an element of (...)

    Semantic Challenges to Scientific Realism.Holger Andreas - 2011 - Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 42 (1):17 - 31.
    This paper is concerned with connections between scientific and metaphysical realism. It is not difficult to show that scientific realism, as expounded by Psillos (1999) clearly qualifies as a kind of metaphysical realism in the sense of Putnam (1980). The statement of scientific realism therefore must not only deal with underdetermination and the dynamics of scientific theories but also answer the semantic challenges to metaphysical realism. As will be argued, the common core of these challenges is the proposition that a (...)

    A Choice-Semantical Approach to Theoretical Truth.Holger Andreas & Georg Schiemer - 2016 - Studies in History and Philosophy of Science Part A 58:1-8.
    A central topic in the logic of science concerns the proper semantic analysis of theoretical sentences, that is sentences containing theoretical terms. In this paper, we present a novel choice-semantical account of theoretical truth based on the epsilon-term definition of theoretical terms. Specifically, we develop two ways of specifying the truth conditions of theoretical statements in a choice functional semantics, each giving rise to a corresponding logic of such statements. In order to investigate the inferential strength of these logical systems, (...)

    Concepts and methods coming from the formal logic of science have played only a very subordinated role in the philosophical analysis of thought experiments so far. The present article, therefore, takes a look at thought experimenting from the perspective of the logic of science in a Carnapian spirit. To this end, the widely discussed refutation of Aristotle′s theory of free falling bodies by Galilei will be investigated. Further, two prominent approaches to thought experimenting are subjected to a closer investigation: first, (...)

    In this book we present a collection of papers on the topic of applying paraconsistent logic to solve inconsistency related problems in science, mathematics and computer science. The goal is to develop, compare, and evaluate different ways of applying paraconsistent logic. After more than 60 years of mainly theoretical developments in many independent systems of paraconsistent logic, we believe the time has come to compare and apply the developed systems in order to increase our philosophical understanding of reasoning when faced (...)
