When asked in 1962 on what he was working Kazimierz Ajdukiewicz replied: Several years ago Polish Scientific Publishers suggested that I pre pare a new edition of The Logical Foundations of Teaching, which I wrote 1 before 1939 as a contribution to The Encyclopaedia of Education. It was a small booklet covering elementary information about logical semantics and scientific methodology, information which in my opinion was necessary as a foundation of teaching and as an element of the education of (...) any teacher. When I recently set to preparing the new edition, I rewrote practically everything, and a booklet of some 100 pages swelled into a bulky volume almost five times bigger. The issues have remained practically the same, but they are now analysed much more thoroughly and the threshold of difficulty is much higher now. The main stress has been laid on the methods used in the empirical sciences, and within that field, on the theory of measurement and the methods of statistical inference. I am now working on the last chapter of the book, concerned with explanation procedures and theory construction in the empirical sciences. When that book, which I intend to entitle Pragmatic Logic, is com pleted I intend to prepare for the press Vol. 2 of my minor writings, 2 Language and Cognition, which will cover some of my post-war pa pers.

Au cœur de la clinique des agirs violents à l’adolescence, cet article présente la modélisation puis les effets du maniement de la limite entre l’intime et le partageable ( lip ), enveloppe de l’espace intersubjectif. Sa double fonction de dilution, part trans-subjective du lien, et de différenciation, part intersubjective, est en souffrance chez ces adolescents. Le commettage, langage subjectif de l’agir violent, déchire l’enveloppe de cet espace, en expulsant des fragments de matière psychique brute archaïque et transgénérationnelle et produit des (...) éprouvés d’empiètements intersubjectifs. L’approche transdisciplinaire permet d’une part de constituer une enveloppe contenante au soin psychique et, d’autre part, soutient la dilution et la traversée momentanée des frontières disciplinaires et subjectales. Dans cette perspective transdisciplinaire, la situation de Jean illustre comment le maniement de la lip dans le processus de soin permet de traiter in situ le dépôt de la violence et de transformer le conflit narcissique ordinaire exacerbé dans le lien père-fils.

Ziel des vorliegenden Aufsatzes ist es, die Existenz von eventuellen Berührungspunkten zwischen Wittgenstein und Ingarden nachzuweisen. Nach einer kurzen Einführung wird anfangs der Hintergrund der Analyse des Problems formuliert. Darauf hin werden die Positionen Wittgensteins Ontologie mit wenigen Begriffen und Ingardens dreistufige Ontologie jeweils skizzenhaft dargestellt und kritisch auf das Vorhandensein von gemeinsamen Grundlinien geprüft. Als Gesichtspunkte gelten dabei folgende Begriffe: Ontologie, Welt und Mensch, Sprache und Ästhetik. Abschließend werden die charakteristischen Merkmale von Berührungspunkten genannt.

The contemporary development of socialist economy is featured not only by high dynamics, but also by essential structural and qualitative changes. The economic policy and the socialist planning in particular tendtowards optimalization of economic growth, then to engage for its proper directions, structure and rythmicality. The every year growing national product ought to be, as it is possible, most suitable and useful for implementation of threefold objective: 1° the better satisfaction with the necessities of population, 2° the quicker modernization of (...) the national economy, and 3° the effective development of the foreign trade as well as the international cooperation.The superiority of a set of social criteria is becoming the general assumption of economic policy. A vision of the future human being and the mature society is determining prospective objectives and aims of the development as well is indicating ways and means for their realization by economic policy.The economic growth is not objective by itself, but has to serve for a comprehensive social advancement. At the same time the factors of social advancement advantageously impact the labour productivity and otherwisethey perform a role of additional stimulatives of the economic growth.The objectives of social advancement should be realized gradually basing on staging patterns of systematic raise of the living standards of the population. A hierarchy and a sequence of satisfaction with the both individual and collective necessities demand a skillful application of the criteria of the economic and social choice. We are using here the principle of social and economic rationality.Hence the factors of social advancement, involving the scientific and technical progress, belang to the fundumatel elements of the present economic and social policy. At the same time objectives and means of modern economic and social advancement are here strictly interlaced. (shrink)

OPER ACCESS. The correspondence between Meinong and Kazimierz Twardowski highlights the relationship between two philosophers who influenced the history of philosophy and psychology in Austria and Poland. The two correspondents discuss, among other things, their epistemological approach and the university politics of their times. In addition, there is an extensive introduction that places the correspondence in its proper historical and philosophical context.

The article reviews the book Die Möglichkeit des Guten. Ethik im 21. Jahrhundert [The Possibility of the Good. Ethics in the 21st Century], by Wilhelm Vossenkuhl.

A simple, journalist scheme indicates that knowledge qualif‌ied to be scientif‌ic directly and fundamentally changes – thanks to its technological applications – the social world. The author presents arguments indicating that things are not that simple for several reasons.Firstly, historians of science argue that many fundamental technologies were created without a clear reference to scientif‌ic knowledge, and the knowledge accumulated by technologists often arises outside the areas of scientific theory. Secondly, we also know that what is technically possible is not (...) necessarily socially possible – not least because of costs, cultural constraints or social practices that we are not willing to give up. Thirdly, it is increasingly clear that the increase in scientif‌ic knowledge is primarily the result of the decision to allocate more and more resources to applied research. This means, however, that the pursuit of knowledge results not so much from the pressure to seek scientif‌ic truth, but from the values that we consider important. Fourthly, this leads to a reorientation in science, which allows contesting the thesis about the objectivity of scientif‌ic cognition in various ways: due to methodological disputes conducted by philosophers of science, the so‑called ‘scientif‌ic method’ does not guarantee the objectivity of scientif‌ic cognition. Consequently, the Enlightenment vision of science, which collapsed under the pressure of post-modernism, ceases to be the basic frame of reference on which we try to improve our collective life. We need this frame only when we cannot imagine this life without appealing to authorities that allow the resolution of essentially undecidable disputes. (shrink)

The story of Abraham and Isaac belongs to the plots frequently recurring in the school drama of sixteenth century Europe. Two related texts are related in the article: Theodore de Bčze’s drama with the title Abraham sacrificanl (staged in Lausanne in 1550) and an anonymous Polish text dating from the end of the sixteenth century Ofiarowanie Izaaka [The Sacrifice of Isaac]. Both the dramas begin with the Prologue, heralding the main events of the story. The works share a three-part, biblical (...) structure (Ofiarowanie Izaaka is composed of three acts), the motif of a father’s love for his son, Abraham’s and Sarah’s care for their son, Abraham’s perplexity and finally the ending, where an angel, a pre-figuration of Christ, appears. The main differences lie in the way in which the protagonists have been grouped - the amusing characters of, among others, Achne, the servant, enrich the play with comical, realistic elements. The similarities between the two texts result not only from their chronology, the common repertoire of school theatres, and the cosmopolitan character of school education. The congruence (despite some apparent differences between the staging possibilities of Lausanne and Cracow) confirms a close relationship between Polish Renaissance drama and the culture of Western Europe and emphasizes its creative character in the presentation of Biblical plots, extending beyond the Bible.

Wollte man die Erkenntnistatigkeit der menschlichen Subjekte einer einfachen Analyse unterziehen, dann konnte man z.B. bei der Frage ansetzen: Wie gehen die Menschen mit Erkenntnis um? Im 21. Jahrhundert wird das Erkennen im Kontext einer (post-)modernen Gesellschaft betrachtet, die viele pluralistische Varianten zulasst: Globale, soziale, Kultur-, Frauen-, Manner-, Bildungs-, Wissenschaftler-, Religionen-, Sportgesellschaft usw. In jeder Form der Gesellschaft wird dem Erkenntnisphanomen eine prinzipielle, wenn auch jeweils spezifische Funktion zugeschrieben, deren objektive Problemstellung auch in ihrem geschichtlichen Horizont gedeutet werden muss, wenn (...) sie sich bewahren soll. Allerdings gilt uberall folgendes Prinzip: Entfaltung jeder Form der Gesellschaft erfordert unbedingt die fortschreitende Erkenntnis. Diese Notwendigkeit hat schon von Anfang an als zuverlassiger Motor fur jedes nur denkbare Modell der Erkenntnistheorie gegolten.". (shrink)

The position of Polish informatics, as well in research as in didactic, has its roots in achievements of Polish mathematicians of Warsaw School and logicians of Lvov-Warsaw School. Jan Lukasiewicz is considered in the world of computer science as the most famous Polish logician. The parenthesis-free notation, invented by him, is known as PN (Polish Notation) and RPN (Reverse Polish Notation). Lukasiewicz created many-valued logic as a separate subject. The idea of multi-valueness is applied to hardware design (many-valued or fuzzy (...) switching, analog computer). Many-valued approach to vague notions and commonsense reasoning is the method of expert systems, databases and knowledge-based systems. Stanis3aw Jaokowski's system of natural deduction is the base of systems of automatic deduction and theorem proving. He created a system of paraconsistent logic. Such logics are used in AI. Kazimierz Ajdukiewicz with his categorial grammar participated in the development of formal grammars, the field significant for programming languages. Andrzej Grzegorczyk had an important contribution to the development of the theory of recursiveness. (shrink)

This paper is a part of a series of lectures on logic delivered by Kazimierz Twardowski in the John Casimir University in Lvov during the first semester of the academic year 1902-1903. This publication of the paper is a hommage to the founder of Lvov-Warsaw School in the centenary of his first lecture in Lvov University.

In the paper some varieties E s n of BCK-algebras with condition defined by W. H. Cornish [1] are considered. A characterization of simple algebras in E s 2 is given and some properties of simple algebras in E s 3 are indicated.

In [60] N. Belnap presented an 8-element matrix for the relevant logic R with the following property: if in an implication A → B the formulas A and B do not have a common variable then there exists a valuation v such that v(A → B) does not belong to the set of designated elements of this matrix. A 6-element matrix of this kind can be found in: R. Routley, R.K. Meyer, V. Plumwood and R.T. Brady [82]. Below we prove (...) that the logics generated by these two matrices are the only maximal extensions of the relevant logic R which have the relevance property: if A → B is provable in such a logic then A and B have a common propositional variable.

In this paper I seek to analyse the following question: how is it that I am able, today, to succeed in fulfilling my goals? My analysis will, I hope, demonstrate that virtues are important because they facilitate this sort of fulfilment. An examination of the classical notion of virtue is thus called for, and this in turn suggests that, at least in certain cases, virtue is connected with luck—that these two belong together. This points towards a new form of contemporary (...) virtue ethics, whose distinctive character will be reflected in the particular significance it invests in the concepts of “qualification” and “competence.” Finally, we are led to Wittgenstein's assertion that “The world of the happy person is other than the world of the hapless person.”.
