    Connecting Actions and States in Deontic Logic
    Studia Logica 105 (5): 915-942. 2017.
    This paper tackles the problem of inference in normative systems where norms concerning actions and states of affairs appear together. A deontic logic of actions and states is proposed as a solution. It is made up of two independent deontic logics, namely a deontic logic of action and a deontic logic of states, interlinked by bridging definitions. It is shown at a language and a model level how an agent should look for norms to follow in a concrete situation. It is pointed out that such specific…Read more

    ABOUT THE PUTTING NAMES TO OBJECTS, I.E. HOW TADEUSZ KOTARBIjSKI TEACHES UNDERSTAND STANISkAW LE3NIEWSKI’S ONTOLOGY S u m m a r y This article presents an attempt to fund Ontology of Stanis;aw Lemniewski on a simple theory with one primitive relation “being denoted by”. Developed theory shows that to the linguistic model of the Ontology can belong only such general names that in their extensions have at least two objects (references) denoted by individual names.

    The paper offers a logical characterisation of multi-step actions in the context of deontic notions of obligation, permission and prohibition. Deontic notions for sequentially composed actions are founded on deontic notions for one-step actions. The present work includes a formal study of situations where execution of a multi-step action has been unsuccessful and provides normative analysis of such actions

    Jerzy Kalinowski’s Logic of Normative Sentences Revisited
    Studia Logica 103 (2): 389-412. 2015.
    The paper tackles two problems. The first one is to grasp the real meaning of Jerzy Kalinowski’s theory of normative sentences. His formal system K 1 is a simple logic formulated in a very limited language . While presenting it Kalinowski formulated a few interesting philosophical remarks on norms and actions. He did not, however, possess the tools to formalise them fully. We propose a formulation of Kalinowski’s ideas with the use of a set-theoretical frame similar to the one presented by Krist…Read more

    A systematics of deontic action logics based on Boolean algebra
    Logic and Logical Philosophy 18 (3-4): 253-270. 2009.
    Within the scope of interest of deontic logic, systems in which names of actions are arguments of deontic operators (deontic action logic) have attracted less interest than purely propositional systems. However, in our opinion, they are even more interesting from both theoretical and practical point of view. The fundament for contemporary research was established by K. Segerberg, who introduced his systems of basic deontic logic of urn model actions in early 1980s. Nowadays such logics are consi…Read more

    Two Faces of Obligation
    In Anna Brożek, Jacek Jadacki & Berislav Žarnić (eds.), Theory of Imperatives from Different Points of View (2), Wydawnictwo Naukowe Semper. 2013.
    In the paper we discuss different intuitions about the properties of obligatory actions in the framework of deontic action logic based on boolean algebra. Two notions of obligation are distinguished–abstract and processed obligation. We introduce them formally into the system of deontic logic of actions and investigate their properties and mutual relations.

    How to Build a Deontic Action Logic
    In Michal Pelis & Vit Puncochar (eds.), The Logica Yearbook 2011, College Publications. 2012.
    The aim of the paper is to point out the modelling choices that lead to different systems of deontic action logic. A kind of a roadmap is presented. On the one hand it can help the reader to find the deontic logic appropriate for an intended application relying on the information considering the way in which a deontic logic represents actions and how it characterises deontic properties in relation to (the representation of) actions. On the other hand it is a guideline how to build a deontic acti…Read more

    Setna — prosta teoria norm i działań
    Filozofia Nauki 3 (4): 155--175. 2008.
    In the first systems of deontic logic obligatoriness, prohibitiveness and permissibility were features of actions. It was a very natural choice, corresponding to the way in which these concepts were used not only in natural language but also in Law and Ethics. It's well known that contemporary systems of deontic logics do not deal with actions any more. They are simply deontic logics of propositions providing for deontic qualification of states of affairs. Such an approach, although might be use…Read more

    In this paper the class of minimal models C ZI for Kiczuk's system of physical change ZI is provided and soundness and completeness proofs of ZI with respect to these models are given. ZI logic consists of propositional logic von Wright's And Then and six specific axioms characterizing the meaning of unary propositional operator "Zm", read "there is a change in the fact that". ZI is intended to be a logic which provides a formal account for describing two kinds of process change: the change from…Read more

    Bity i byty. O pewnym mało znanym zastosowaniu ontologii
    Filozofia Nauki 3 (59): 121--140. 2007.
    In this paper we are focused on the relation between an Ontology (with the capital "O") qua philosophical discipline and an ontology (with the lowercase "o") qua branch of Computer Science. In our view "Ontology" refers to all philosophical groups or schools which take some position on the reality. The meaning of 'ontology' in the second case is not that easy to grasp because of the variety of artefacts which are called 'ontologies' and many activities - aiming at creating the ontologies - calle…Read more

    A norm-giver meets deontic action logic
    Logic and Logical Philosophy 20 (1-2): 2011. 2011.
    In the paper we present a formal system motivated by a specific methodology of creating norms. According to the methodology, a norm-giver before establishing a set of norms should create a picture of the agent by creating his repertoire of actions. Then, knowing what the agent can do in particular situations, the norm-giver regulates these actions by assigning deontic qualifications to each of them. The set of norms created for each situation should respect (1) generally valid deontic principles…Read more

    Doing the right things–trivalence in deontic action logic
    Trivalent Logics and Their Applications. 2012.
    Trivalence is quite natural for deontic action logic, where actions are treated as good, neutral or bad.We present the ideas of trivalent deontic logic after J. Kalinowski and its realisation in a 3-valued logic of M. Fisher and two systems designed by the authors of the paper: a 4-valued logic inspired by N. Belnap’s logic of truth and information and a 3-valued logic based on nondeterministic matrices. Moreover, we combine Kalinowski’s idea of trivalence with deontic action logic based on bool…Read more

    In the paper we provide an overview of issues related to the models used in the research on the logic of norms and actions. We present two models of the variability of the world: temporal (acyclic) and atemporal (cyclic). In the first one the past is always clearly defined, and the future is potentially “branched”. The second type of model allows for a return to the situation that took place. Next we describe different approaches towards agency modeling. We present the most important paradigms, …Read more

    We investigate a specic model of knowledge and beliefs and their dynamics. The model is inspired by public announcement logic and the approach to puzzles concerning knowledge using that logic. In the model epistemic considerations are based on ontology. The main notion that constitutes a bridge between these two disciplines is the notion of epistemic capacities. Within the model we study scenarios in which agents can receive false announcements and can have incomplete or improper views about oth…Read more

    Spór o wartość logiczną norm. Logika norm a logika deontyczna
    Roczniki Filozoficzne 52 (1): 293-315. 2004.
    The main purpose of this paper was the trial to answer the question if norms can function as premises or conclusions in logical inferences. According to definition of logical inference, the parts of its may be only sentences (in indicative mood) which are true or false. The logic, which accepts that norms are the true and false propositions, can be named the Logic of Norms. Otherwise the logic, which reject that norms are true and false propositions, we name Deontic Logic. The last one, in order…Read more
