[full article, abstract in English; only abstract in Lithuanian] The paper deals with the problem of the “two Barbaras” in the Aristotelian modal syllogistic. The problem consists in Aristotle’s differing views on two at a first sight similar in nature syllogisms of mixed assertoric (X) and necessary (L) premises: Barbara LXL and Barbara XLL. The fact that Aristotle believed the first syllogism to be valid and the second one – not, has been received either 1) negatively, because both Barbaras have been held to be invalid, or 2) negatively, because both Barbaras have been held to be valid, or 3) positively, by giving a reason why the two Barbaras differ. We commit ourselves to the position (3) by proving that modal propositions for Aristotle have their modalities de dicto and that Aristotelian modal operators act according to their own separate rules where only the type of the modality of a major premise is relevant for the modal status of the conclusion.

[full article, abstract in English; only abstract in Lithuanian] This article presents the results of a broader research project which aims to argue for the normativity of scientific laws. Usually scientific laws are regarded as descriptive, which contrasts them to prescriptive norms. To show their normativity, I utilize the logical account of explicitly normative systems by Carlos Alchourrón and Eugenio Bulygin (1971). I identify the characteristic elements of normativity and analyse accounts of implicit normativity in science using those terms to show the affinities of explicit and implicit normativities. The research project continues with the substantiation of the normativity of scientific laws in detail and the results will be presented in Normativity of Scientific Laws (II) (Mets 2018).

[full article, abstract in English; only abstract in Lithuanian] Nickles advocates scientific antirealism by appealing to the illusion hypothesis, the pessimistic induction over scientific theories, Darwin’s evolutionary theory, and the problem of underdetermination. I object that both the illusion hypothesis and evolutionary theory clash with the pessimistic induction and with the problem of underdetermination. I also argue that Nickles’s positive philosophical theories are subject to Park’s pessimistic induction over antirealists. Finally, I apply the Golden Rule to antirealists, viz., if antirealists do not want scientists to run the pessimistic induction over antirealists, antirealists ought not to run the pessimistic induction over scientific theories.

[full article, abstract in English; only abstract in Lithuanian] This paper proposes a new pragmatic interpretation of the Frege–Geach problem and presents a possible solution using a model of ascriptive legal language. The first section includes the definition of the Frege–Geach problem. In the second section, I analyze the content of Geach’s critical argument against prescriptivism in ethics. I discuss what Geach means by ascriptivism, why he mixes it with prescriptivism, and why a particular article by Herbert Hart became the subject of criticism by Geach. The third section proposes a possible solution to the Frege–Geach problem based on the explication of the assertoric force of ascriptive legal utterances and the performativity of legal language.

[full article, abstract in English; only abstract in Lithuanian] Walton’s thesis of transparency of photographs has spurred much dispute among critics. One of the popular objections is spatial agnosticism, an argument that concerns the inertia of egocentric spatial information vis-a-vis a photograph. In this paper, I argue that spatial agnosticism fails. Spatial agnostics claim, for a wrong reason, that a photographic image cannot carry egocentric spatial information. I argue that it is the disjuncture of the photographic world in which the depicted object situated from the space in which the viewer of the photograph resides that renders the photograph spatially agnostic. It is the timeless photographic world rather than the photographic object that renders egocentric spatial information inert. With this new formulation of spatial agnosticism, I propose that spatial agnosticism needs to be coupled with the temporal dimension (the A-theory of time) in the efforts to refute the thesis of transparency of photographs.

[full article, abstract in English; only abstract in Lithuanian] This article provides an overview of the main themes and controversies in the restorative justice discussions in Europe and the US with special attention to the role of victims and mediators. This discussion is contextualized through a short description of the history of both state-centered and community-oriented restorative systems in response to law violation. Indigenous and pre-state formation responses to crime have predominantly been of a restorative nature with an interest in healing the harm experienced by all participants, aimed at addressing social problems and strengthening the community as a whole.

[full article, abstract in English; only abstract in Lithuanian] The aim of this paper is to focus on Arne Nass’s phenomenological method and some of its anthropological and cosmological implications. Nass’s Ecology, Community and Lifestyle, in fact, can be fruitfully read as an example of phenomenological inquiry, in which the notion of “spontaneous experience” plays a fundamental role. This method leads Nass to develop a “relational ontology,” in which the “ecological self” is seen as a “relational junction within the total field.” In addition, I show how Tymieniecka’s philosophical thought can offer us the proper eco-phenomenological perspective to better understand Nass’s Ecosophy T.

[full article, abstract in English; only abstract in Lithuanian] This paper offers a typology of different forms of political violence, linking them in a continuum and in an interdependent field of forces. The forms identified are systemic violence, institutional violence, group violence, armed struggle, terrorism and war. In the final section, after discussing how these types of violence influence one another, a strategy is suggested for their simultaneous reduction.

The problem of de re modality is how, if at all, one can make sense of it. Most who have discussed this problem have assumed that modality de dicto is relatively unproblematic. It is, rather, the interpretation of sentences involving, within the scope of modal operators, singular terms or free variables which is thought to give rise to grave—and in the view of some, insuperable—difficulties. Quine has two arguments against the intelligibility of de re modality: a “logical” and a “metaphysical” one. That the “logical” argument is central to Quine’s attack is surely indisputable. But my claim that it is his basic argument is, in effect, denied by Kit Fine. I can (and do) agree with Fine that there are some significant differences between the two arguments. The most important question, for my purposes, is whether he is right to claim that the two arguments have force independently of one another.

Abstract We introduce a modal separation logic MSL whose models are memory states from separation logic and the logical connectives include modal operators as well as separating conjunction and implication from separation logic. With such a combination of operators, some fragments of MSL can be seen as genuine modal logics whereas some others capture standard separation logics, leading to an original language to speak about memory states. We analyse the decidability status and the computational complexity of several fragments of MSL, obtaining surprising results by design of proof methods that take into account the modal and separation features of MSL. For example, the satisfiability problem for the fragment of MSL with $\Diamond $, the difference modality $\langle \neq \rangle $ and separating conjunction $\ast $ is shown Tower-complete whereas the restriction either to $\Diamond $ and $\ast $ or to $\langle \neq \rangle $ and $\ast $ is only NP-complete. We establish that the full logic MSL admits an undecidable satisfiability problem. Furthermore, we investigate variants of MSL with alternative semantics and we build bridges with interval temporal logics and with logics equipped with sabotage operators.

[full article, abstract in English; abstract in Lithuanian] We will hereinafter discuss the author’s philosophy on gnoseological and historical premises. More precisely, by exploring the genealogy of the idea of the “Death of the Author” from modernism to postmodernism, we will analyse the concepts and ideologies that have become the stratagem of the denial of western literary canon, as well as the denial of equilibrium between philosophical and literary identity and universality. By treating the works of philosophers, authors, and fundamental semiologists who perpetuated the idea of the Death of the Author, we will observe how the latter gradually fled from the philosophy of doubt and as mea culpa admitted that without the author’s authority the philosophical and literary legacy is no longer the theatre of memory, but the abyss of oblivion. Moreover, with fundamental examples, we will observe the influence of this philosophy in the process of studying of the literature.
