    "Twardowski's On the Content and Object of Presentations (1894) is one of the most influential works that Austrian philosophy has left to posterity. The manuscript Logik (1894-1895) supplements that work and allows us to reconstruct Twardowski's theory of judgment. These texts raise several issues, in particular whether Twardowski accepts propositions and states of affairs in his theory of judgment and whether his theory is acceptable. This article presents Twardowski's theory, shows that he accepts states of affairs, that he has a notion of proposition, and that his theory is interesting and sophisticated."

    "In several manuscripts, written between 1894 and 1897, Twardowski developed a new theory of judgment with two types of judgment: existential and relational judgments. In Zur Lehre he tried to stay within a Brentanian framework, although he introduced the distinction between content and object in the theory of judgment. The introduction of this distinction forced Twardowski to revise further Brentano's theory. His changes concerned judgments about relations and about nonpresent objects. The latter are considered special cases of relational judgments. The existential judgments are analyzed in a Brentanian way."

    "Among the unpublished writings of Kazimierz Twardowski so far there is an essay in which Twardowski tries to embed the concept of an intentional object' within a theory that comprises at the same time psychological, logical and grammatical aspects. This theory of actions' and products' is presented here and several applications of the theory are discussed. The central question thereby is whether the distinction between actions and products enables Twardowski to counter the objection of psychologism raised against him. Having explained Twardowski's position we describe from an editorial point of view the text in which his theory is transmitted. The text itself is published according to the given editorial principles after this introduction."

    Twardowski offers four arguments to show that the content and object of a presentation can never be same. These conclusions are challenged by a formal diagonal counterexample in which it is possible for the content and object of a thought to be precisely identical.

    Twardowski's reduction and the act-Content-Object structure of psychological experience may nevertheless be upheld in somewhat different form not as an exclusive but as a nonexclusive kind of distinction."

The work bears the detail presentation of Twardowski's semiotic views, showing that his theory consists in the psycho-physical conception of signs, the functional conception of expression, the noematic conception of sense, and the discrepant conception of language.

    "The Scholar, who at the start of this century has indicated the direction towards philosophy not only of the School of Leopoli but, in a certain sense, of the whole Poland, was Kazimierz Twardowski. This study presents briefly his biography and his activity as teacher and as organiser. The knowledge of the setting in which he was formed in the intellectual attitude of the founder of the Philosophical School of Leopoli-Warsaw can facilitate a brief exposition of the theories of Twardowski. He was an excellent Brentanist, and in the development of this doctrine he stands midway between F. Brantano and E. Husserl. K. Tardowski is the founder of the School which represents a relevant trend in modern analytical philosophy."

    This volume contains a selection of papers from the conference "The Theory of Objects in Central Europe. The Austrian-Polish Connection: Meinong and Twardowski" held in December 1989 in Kraków. It was supported and sponsored by the Jagiellonian University, Centro Studi per la Filosofia Mitteleuropea, The National Research Project "Sign-Language-Reality", and The Institute of Austrian Culture in Warsaw. The conference was organized by Prof. Jan Wolenski with dr. Georg Jankovic's generous assistance.

    Alexius Meinong and Kazimierz Twardowski studied philosophy at the University of Vienna at the end of XIX century. Both were under a great influence of Franz Brentano, who is considered the father of contemporary theory of intentionality. He viewed intentionality as the crucial feature of consciousness consisting in „directness to an object". Such conception should presuppose some general theory of objects of consciousness. Meinong and Twardowski adopted Brentano's idea of intentionality subsequently elaborating their own ontologies of objects. What is common in the views of the two philosophers, barring many differences, is that they assume an extensive sphere of non-existent objects that can be possibly objects of intentional acts.

    Nowadays there is a growing interest in theories of intentionality and intentional objects on the part of analytic philosophy as well as phenomenology. That is why there is also a renaissance of Meinong's and Twardowski's philosophical thought, although the former philosopher is much better known, more popular, and, what follows, more inspiring. The main purpose of the conference that took place in Kraków was to investigate, from various historical and theoretical perspectives, theories of objects created by the two of Brentano's followers. It is to be regretted that the present volume does not fill a serious gap in philosophical literature: no paper is devoted to direct comparison of Meinong and Twardowski. Nevertheless we hope that the papers collected in the volume may contribute to better understanding of the two philosophers and prepare the ground for such a comparative study.

    F. Modenato, in her essay, traces the development of Meinong's idea of relations while linking his views with the views of Hume and Locke. She is concentrating on epistemological relevance of the idea. Relations are treated by Meinong as some complexities and both relations and complexities are higher-order objects. Higher-order objects play the central role in Meinong's theory of knowledge and are of great importance to his ontology.

    L. Albertazzi points to some Kantian motives in Twardowski's ontology. The Polish philosopher distinguishes several categories of objects which, according to Albertazzi's interpretation, correspond closely to that distinguished by Kant. In particular, 'the object in general' may be taken as Kant's transcendental object, and 'the general object' as a universal presented individually in the subject of proposition.

    R. Poli argues in his paper that many elements of Wolff's ontology can be found in Twardowski's theory of objects. Both philosophers conceive objects as possible wholes. For Twardowski, being an object is ontologically prior to having existence and it is enough for being an object to be representable in an act of presentation.

    J.J. Jadacki presents a comprehensive survey of Twardowski's ontological (metaphysical) and epistemological views. On this basis he reconstructs the philosopher's descriptive semiotics focusing his attention on the theory of judgment.

    Additionally, Jadacki carries out a formal semantic analysis of Twardowski's semiotics.

    J. Wolenski considers the main traditional views of 'being' and wonders if 'being' could be situated somewhere in the formal hierarchy of concepts. He comes to the conclusion that "being" expresses no concept at all and, what follows, it has the syncategorematic character as Twardowski claimed. Wolenski proposes a completion of Twardowski's claim by appealing to modern logic and Lesniewski's ontology.

    D. Jacquette sketches informally the principles of Meinongian semantics and shows how the semantics can be applied in formalisation of scientific laws. By contrast to extensionalist models of scientific discourse which admit only existent objects, in Meinongian semantics the reference to ideal and non-existent objects is possible. Many problems of contemporary philosophy of science such as, for example, the justification of induction and confirmation can be uniformely treated and solved on the ground of Meinong's theory.

    J. Pasniczek proposes quite a simple logic which obeys the main theses of Meinong's theory of objects. This logic resembles closely the classical predicate logic with respect to syntax and semantics (it is basically extensional). Despite that resemblance, the proposed logic is associated with very rich ontology of objects including various kinds of non-existent objects.

    "This paper advocates the view that thoughts which are qualitatively the same are also numerically identical. The point of departure is the puzzle: if thoughts are unchanging and eternal inhabitants of a "third realm", then it is mysterious how we grasp them, whereas, the assumption that they are outputs of some mental processes casts doubt on the possibility of communicating thoughts. To solve the puzzle Twardowski's teaching on actions and their products is applied and further elaborated."

    "Largely ignored in Germany during the nineteenth century, Bolzano was certainly better known in Austria, in particular among Brentano's students, who enthusiastically studied his Theory of Science. In this respect it makes sense to speak of Bolzano as belonging to a tradition of Austrian philosophy. Yet an examination of the reception of Bolzano's ideas among Brentano's students indicates that he was not always well understood. This article discusses a particular case, Twardowski's reaction to Bolzano's theory of representation."

    "Why have Polish philosophers fared so badly as concerns their admission into the pantheon of "Continental philosophers?" Why, for example, should Heidegger and Derrida be included in this pantheon, but not Ingarden or Tarski? Why, to put the question from another side, should there be so close an association in Poland between philosophy and logic, and between philosophy and science? We distinguish a series of answers to this question, which are dealt with under the following headings: (a) the role of socialism; (b) the disciplinary association between philosophy and mathematics; (c) the influence of Austrian philosophy in general and of Brentanian philosophy in particular; (d) the serendipitous role of Twardowski; (e) the role of Catholicism. The conclusion of the paper is that there is no such thing as 'Polish philosophy' because philosophy in Poland is philosophy per se, it is part and parcel of the mainstream of world philosophy -- simply because, in contrast to French or German philosophy, it meets international standards of training, rigour, professionalism and specialization."

    "In spite of the historical proximity of S. Lesniewski to K. Twardowski, ari attempt to look at Twardowski's heritage through Lesniewski's eyes leads to striking results. Firstly, it results in a wider framework than Lesniewski's Elementary Ontology and secondly, it involves a transition from Formal Ontology to Formai Phenomenology. In this paper an extension of Leíniewskis's Non-Elementary Ontology is presented which is suitable for investìgating Twardowski's Theory of Presentation."

This paper discusses the development of the mentioned distinction from Bolzano to Twardowski. Views of Zimmermann, Brentano, Meinong, Höfler are taken into account; also some objections of Husserl against Twardowski are discussed and evaluated. The paper also stresses the general philosophical significance of Twardowski's work."

    "This paper intends to show that the rise of semantics in Poland was related to Kazimierz Twardowski and his understanding of mental acts as intentional (in Brentano's understanding plus the principally realistic conception of intentional objects). Twardowski's theory of language was consequently semantic considering words as products of mental acts and as referring to the world. This view was then refined by Twardowski's students, in particular Stanislaw Lesniewski and Tadeusz Kotarbinski. Both were teachers of Alfred Tarski, the founder of modern formal semantics. These facts suggest that the intentional conception of language was an important philosophical context of Tarski's work."
