This paper is my last word, in the present journal, in the debate I have been having with Walter Block on the subject of evictionism as an alleged libertarian “third way,” capable of transcending the familiar “pro-life” and “pro-choice” dichotomy. In this debate, I myself defended what might be regarded as a qualified “pro-life” position, while Block consistently argued that the mother is morally allowed to expel the fetus from her womb provided that no non-lethal methods of its eviction are (...) available. While my position articulated in this paper contains an element of what Block might consider a concession on my part—i.e., an explicit declaration that abstaining from lethal evictions of fetuses conceived as a result of rape is a libertarian duty, but only an imperfect one—I continue to regard the unqualified support of evictionism as indefensible on libertarian grounds.

This paper defends the Blockian Proviso against its critics, Kinsella in particular, and interprets it as a law of non-contradiction in the theory of just property rights. I demonstrate that one may not lawfully appropriate in such a way as to forestall others from appropriating an unowned land because such appropriation would result in conflict-generating norms, and conflict-generating norms are not rationally justifiable and just norms. The Blockian Proviso, which precludes forestalling, operates therefore at the level of original appropriation and (...) determines, according to the homestead principle of justice in first acquisition, what may and what may not be lawfully appropriated. Hence, the Blockian Proviso is not an add-on to the homestead principle but part and parcel thereof. (shrink)

Modern technology offers an increasing number of tools for teaching mathematics, but technology adoption in schools encounters many barriers. The Technology Acceptance Model explains that technology usage is dependent on intentions, which rest on perceived ease of use and perceived usefulness. Less is known about the relationship between intentions and actual behaviour. In the current study we show that the level of cognitive investment on the part of the teachers, captured by the construct of Need for Cognition (NC), is crucial (...) in the use of technology in mathematical instruction, while controlling for a variety of background factors. Furthermore NC moderates the relationship between intentions and technology use, such that high NC weakens the relationship between the perceived usefulness of technology in pedagogy and its actual use.

This book is a study in the logic of questions (sometimes called erotetic logic). The central topics in erotetic logic have been the structure of questions and the question-answer relationship. This book doesn't neglect these problems, but much of it is focussed on other issues. The main subject is the logical analysis of certain relations between questions and the contexts of their appearance. And our aim is to elaborate the conceptual apparatus of the inferential approach to the logic of questions. (...) Questions are asked for many reasons and for different purposes. Yet, before a question is asked or posed, a questioner must arrive at it. In many cases arriving at a question resembles coming to a conclusion: there are some premises involved and some inferential thought processes take place. If we agree that a conclusion need not be "conclusive", we may say that sometimes questions can play the role of conclusions. But questions can also perform the role of premises: we often pass from some "initial" question to another question. In other words, there are inferential thought processes - we shall call them erotetic inferences - in which questions play the roles of conclusions or conclusions and premises. The inferential approach to the logic of questions focusses its attention on the analysis of erotetic inferences. This book consists of eight chapters. (shrink)

In this commentary, I critically assess Rex Welshon’s position on the neural substrates of ownership unity. First, I comment on Welshon’s definition of ownership unity and underline some of the problems stemming from his phenomenological analysis. Second, I analyze Welshon’s proposal to establish a mechanistic relation between neural substrates and ownership unity. I show that it is insufficient and defend my own position on how neural mechanisms may give rise to whole subjects of experience, which I call the neuro-integrative account (...) of consciousness. Lastly, I comment on Welshon’s philosophical contribution and claim that it leaves the reader theoretically stranded. (shrink)

Can ownership status influence probability judgements under condition of uncertainty? In three experiments, we presented our participants with a recording of a real horse race. We endowed half of our sample with a wager on a single horse to win the race, and the other half with money to spend to acquire the same wager. Across three large studies, we found the endowment effect – owners demanded significantly more for the wager than buyers were willing to pay to acquire it. (...) However, we also found that probability estimates of each horse winning the race did not differ between owners and non-owners of the betting slip. Our results demonstrate that distorted perception of probability is unlikely to be a mechanism explaining the endowment effect. (shrink)

According to contemporary understanding of the universal tree of life, the traditionally recognized kingdoms of eukaryotic organisms—Protista, Fungi, Animalia and Plantae—are irregularly interspersed in a vast phylogenetic tree. There are numerous groups that in any Linnaean classification advised by phylogenetic relationships would form sister groups to those kingdoms, therefore requiring us to admit them the same rank. In practice, this would lead to the creation of ca. 25-30 new kingdoms that would now be listed among animals and plants as “major (...) types of life”. This poses problems of an aesthetic and educational nature. There are, broadly speaking, two ways to deal with that issue: a) ignore the aesthetic and educational arguments and propose classification systems that are fully consistent with the Hennigian principles of phylogenetic classification, i.e. are only composed of monophyletic taxa; b) ignore Hennigian principles and bunch small, relatively uncharacteristic groups into paraphyletic taxa, creating systems that are more convenient. In the paper, I present the debate and analyze the pros and cons of both options, briefly commenting on the deeper, third resolution, which would be to abandon classification systems entirely. Recent advances in eukaryotic classification and phylogeny are commented in the light of the philosophical question of the purpose and design principles of biological classification systems.

The article is an attempt to indicate the presence of the ethics of civic virtues in Polish ethics, both old and modern, which is worth in-depth attention. Problems of civic morality have constantly accompanied ethics and morality in Poland since the Renaissance. Its content was usually a reflection of critical reflection on the defects of civic morality, especially of the nobility, and over time of the bourgeoisie, and at the same time it was normatively constructive as historical and political changes (...) and the scope of civil society expanded, formulating “the ideal of the citizen in a democratic system”. The author of the article selects from the history of Polish ethics the most important figures who address the issue of virtue ethics, showing its constant presence in history, using the prism of civic ethos as a key element for the ethics of public life. It was difficult to prove the existence of a specialized section of civic ethics, but the normative civic ethos can be reconstructed from the perspective of the ethics of virtue and social ethics in a broader sense. From the historical perspective, this ethos appears both as a certain set of practices, which was only outlined in the context of the article, and as an ordered product of normative thought.

Three semantic relations are analyzed: the relation of implication of a question by a question and a set of declarative sentences, the relation of implication of a question by a question, and the relation of strong implication of a question by a question and a set of declarative sentences. The connections between these concepts and the concepts of relative soundness, partial answerhood and presupposition are examined. The principal results are theorems about, to speak generally, epistemic reducibility of well-posed questions to (...) sequences of implied yes-no questions. (shrink)

Inferential erotetic logic and inquisitive semantics give accounts of questions and model various aspects of questioning. In this paper we concentrate upon connections between inquisitiveness, being the core concept of INQ, and question raising, characterized in IEL by means of the concepts of question evocation and erotetic implication. We consider the basic system InqB of INQ, remain at the propositional level and show, inter alia, that: a disjunction of all the direct answers to an evoked question is always inquisitive; a (...) formula is inquisitive if, and only if it evokes a yes–no question whose affirmative answer expresses a possibility for the formula; inquisitive formulas evoke questions whose direct answers express all the possibilities for the formulas, and each question erotetically implies a question whose direct answers express the possibilities for the direct answers to the implying question.

"The importance of questions is beyond doubt. But the degree of attention paid to them in logic and linguistics is still less than they deserve." What is a question? How to represent questions in formal languages? How to model reasoning in which questions are involved? Can we prove anything by means of pure questioning? How to model goal-directed problem solving? These are the main issues of Andrzej Wi niewski's "Questions, Inferences, and Scenarios." This book offers a state-of-the-art exposition of Inferential (...) Erotetic Logic, that is, an approach to the logic of questions focused on inferences which lead to questions as conclusions. Wi niewski characterizes semantic relations which determine validity of these inferences within the framework of Minimal Erotetic Semantics, applicable to a wide range of formal languages. He elaborates in detail the concept of erotetic search scenario, a tool for modelling problem solving. Moreover, the author presents some applications of Inferential Erotetic Logic in proof theory. Andrzej Wi niewski is one of the most prominent contemporary researchers in the logic of questions. Currently, he is a full professor at the Department of Logic and Cognitive Science, Institute of Psychology, Adam Mickiewicz University in Pozna, Poland. (shrink)

First-order logic is formalized by means of tools taken from the logic of questions. A calculus of questions which is a counterpart of the Pure Calculus of Quantifiers is presented. A direct proof of completeness of the calculus is given.

The concept of search scenario is explicated in terms of erotetic logic, i.e., the logic of questions. Different kinds of erotetic search scenarios are characterized. The basic logical properties of erotetic search scenarios are analyzed.

This paper argues for the idea that the logic of questions should focus its attention on the analysis of arguments in which questions play the role of conclusions. The relevant concepts of validity are discussed and the concept of the logic of questions of a semantically interpreted formalized language is introduced.

The concept of erotetic argument is introduced. Two relations between sets of declarative sentences and questions are analysed; and two classes of erotetic arguments are characterized.

Our aim is to express in exact terms the old idea of solving problems by pure questioning. We consider the problem of derivability: "Is A derivable from Δ by classical propositional logic?". We develop a calculus of questions E*; a proof (called a Socratic proof) is a sequence of questions ending with a question whose affirmative answer is, in a sense, evident. The calculus is sound and complete with respect to classical propositional logic. A Socratic proof in E* can be (...) transformed into a Gentzen-style proof in some sequent calculi. Next we develop a calculus of questions E**; Socratic proofs in E** can be transformed into analytic tableaux. We show that Socratic proofs can be grounded in Inferential Erotetic Logic. After a slight modification, the analyzed systems can also be viewed as hypersequent calculi. (shrink)

ABSTRACT A review of two of the strands of cultural studies that Mark Fenster contends are superior to Murray Edelman’s analysis of mass public opinion—Gramsci’s theory of hegemony, and Bourdieu’s sociology—and a more general look at work in the field of cultural studies suggests that all of these alternatives suffer from severe theoretical and methodological limitations. Future studies of culture and politics need to pose questions similar to the ones that preoccupied Edelman, but they must move beyond the political and (...) interpretive biases that have dominated cultural studies (some of which Edelman shared), as well as the questionable view of “ideology” as a matter of elite domination of the masses, rather than as a mediating, constitutive force in the process of individual opinion formation.

The concepta question is reducible to a non-empty set of questions is defined and examined. The basic results are: (1) each question which is sound relative to some of its presuppositions is reducible to some set of binary (i.e. having exactly two direct answers) questions; (b) each question which has a finite number of direct answers is reducible to some finite set of binary questions; (c) if entailment is compact, then each normal question (i.e. sound relative to its presuppositions) is (...) reducible to some finite set of binary questions.

This paper develops a new proof method for two propositional paraconsistent logics: the propositional part of Batens' weak paraconsistent logic CLuN and Schütte's maximally paraconsistent logic Φv. Proofs are de.ned as certain sequences of questions. The method is grounded in Inferential Erotetic Logic.

ABSTRACT The Habermasian ideal of deliberation has long been seen as an extension of, and complement to, political action. But Diana Mutz's empirical studies of face-to-face interactions reveal a conflict between political participation and political deliberation: The more likely people are to be exposed to diverse political opinions, the less likely they are to participate, and those who participate most tend to have the least exposure to diverse political opinions. She hypothesizes, however, that the infrastructure of the Internet might allow (...) for the creation of a forum for online political debate that is sufficiently generalizable to result in deliberation. Champions of the Internet's democratic potential similarly praise its diversifying influence on political discussion and the ways in which it lowers barriers to access. Yet there is little evidence to suggest that new technologies have truly transformed political action or produced meaningful deliberation at significant levels. It appears that many of the trends and behaviors Mutz identifies in face-to-face interaction apply to digital interaction as well. (shrink)

The Mengerian-Misesian tradition in economics is also known as the causal-realist approach – in other words, it studies the causal structure of economic phenomena conceived of as outgrowths of real human actions. Thus, it finds verbal descriptions and declarations economically meaningful only insofar as they can be linked with demonstrated preferences and their causal interactions. In this paper, I shall investigate how the approach in question bears on topics such as the economic calculation debate, deliberative democracy, and the provision of (...) public goods. In particular, in the context of discussing the above topics I shall focus on market entrepreneurship understood as a crucial instance of “practicing what one preaches” in the ambit of large-scale social cooperation. In sum, I shall attempt to demonstrate that the Mengerian-Misesian tradition offers unique insights into the logic of communicative rationality by emphasizing and exploring its indispensable associations with the logic of action.

The concepts of question evocation and erotetic implication play central role in Inferential Erotetic Logic. In this paper, deduction theorems for question evocation and erotetic implication are proven. Moreover, it is shown how question evocation by a finite non-empty set of declaratives can be reduced to question evocation by the empty set, and how erotetic implication based on a finite non-empty set of declaratives can be reduced to a relation between questions only.

By and large, Inferential Erotetic Logic (IEL, for short) is an approach to the logic of questions which puts in the centre of attention inferential aspects of questioning. IEL is not an enterprise of the last few years only. The idea originates from the late 1980s. It evolved through time. Initially, the stress was put on the phenomenon of question raising. This changed gradually, as some forms of reasoning that involve questions have appeared to be analyzable by means of the (...) conceptual apparatus developed. In this essay I present the basics of IEL and comment on them. Most, though not all, of the ideas discussed here have been scattered across my earlier publications. The invitation from the organizers of the Asking and Answering workshop (Greifswald, September 2020) resulted in an attempt of presenting the themes of IEL in a concise but, as I hope, also comprehensible way.

We consider structures of the form, where Φ and Ψ are non-empty sets and is a relation whose domain is Ψ. In particular, by using a special kind of a diagonal argument, we prove that if Φ is a denumerable recursive set, Ψ is a denumerable r.e. set, and R is an r.e. relation, then there exists an infinite family of infinite recursive subsets of Φ which are not R -images of elements of Ψ. The proof is a very elementary (...) one, without any reference even to e.g. the -theorem. Some consequences of the main result are also discussed. (shrink)

Artykuł jest szkicem odpowiedzi na pytanie: dlaczego etyka Tadeusza Kotarbińskiego, będąc w istocie typem do brze znanej filozofom etyki autonomicznej, a normatywnie bliska ideom chrześcijańskiego miłosierdzia, stała się popularna i żywo dyskutowana w Polsce drugiej połowy XX wieku. Autor omawia ówczesne dyskusje, wskazując na powody zainteresowania stanowiskiem etycznym Kotarbińskiego w kręgu polskich myślicieli chrześcijańskich. Jego źródeł upatruje w reakcji na program uniezależnienia postaw etycznych od sporów światopoglądowych. Jednocześnie zwraca uwagę, że w kręgu szkoły lwowsko–warszawskiej i jej wpływów etyka Kotarbińskiego miała (...) poparcie, ale i spotkała się z krytyką. Zastrzeżenia epistemologiczne wobec niej wysuwała Maria Ossowska. Po stronie Kotarbińskiego opowiedział się Tadeusz Czeżowski, występujący z bardziej precyzyjnie sformułowaną ideą etyki empirycznej, wykazując z czasem, że jest to etyka typu aksjomatyczno–dedukcyjnego, a nie indukcyjnego. Akceptując intuicjonizm jako epistemologiczny fundament etyki, do normatywnych idei Kotarbińskiego nawiązywali w sposób twórczy również Ija Lazari–Pawłowska i Marian Przełęcki. Autor przekonuje, że nie jest bezzasadnym przypuszczenie, że program uniwersalnej etyki, niezależnej od sporów światopoglądowych i religijnych, wpłynął także na Marka Fritzhanda interpretację etyki w marksizmie oraz korespondował z tendencjami do budowania etyki dialogu i odpowiedzialności w polskich dyskusjach etycznych w czasach dominacji etyki światopoglądowej.
