Kazimierz Twardowski (20/10/1866, Vienna - 11/02/1938, Lvov) is most commonly known as the teacher of great philosophers and the founder of the Lvov-Warsaw School. As a philosopher however, he is primarily remembered for his famous comparison of the contents and objects of various kinds of representations, a comparison that remains enshrined in European thought. In fact, he attained important results in many other branches of philosophy as well. For instance, in (descriptive) ontology, he laid the foundations for the modern theory of formal structure of objects, and he introduced the theoretically fruitful pair of terms, action-product. In epistemology, he developed a profound analysis of the notion and criteria of truth; and he provided a forceful account of the errors underlying relativist theories of truth. In methodology, he drew an explicit distinction between the processes of discovering, systematising, and grounding in science, and he offered accurate descriptions of the nature of psychology and other humanities. In (philosophical) logic, he offered decisive arguments on behalf of the idiogenetic conception of judgement, and he improved the traditional typology of adjectives. These achievements are of significance that is not only historical. Kazimierz Twardowski's work, formulated in plain, precise language, are instructive and inspiring for contemporary students of philosophy.

Kazimierz Twardowski (1866-1938) is the founder of the Lvov-Warsaw School with its strong tradition in logic and its scientific approach to philosophy. Twardowski’s unique way of doing philosophy, his method, is of central importance for understanding his impact as a teacher. This method can be understood as a philosophical grammar, which is also how Leibniz conceived his universal language of thought. Analytic philosophy in the twentieth century can be characterized by its opposition to psychologism, on the one hand, and its opposition to metaphysics, on the other. This is changing now, as questions within the philosophy of mind and metaphysics are raised by analytic philosophers today. Maria van der Schaar shows in her book that we can improve our analytic methods by making use of Twardowski’s philosophical grammar. Twardowski’s positive attitude to psychology and metaphysics may also help us to develop an analytic metaphysics and to get a better understanding of the relation between psychology and philosophy.

The book discusses Franz Brentano’s impact on Austrian philosophy. It contains both a critical reassessment of Brentano’s place in the development of Austrian philosophy at the turn of the 20th century and a reevaluation of the impact and significance of his philosophy of mind or ‘descriptive psychology’ which was Brentano's most important contribution to contemporary philosophy and to the philosophy in Vienna. In addition, the relation between Brentano, phenomenology, and the Vienna Circle is investigated, together with a related documentation of Brentano's disciple Alfred Kastil (in German). The general part deals with the ongoing discussion of Carnap's "Aufbau" (Vienna Circle Lecture by Alan Chalmers) and the philosophy of mind, with a focus on physicalism as discussed by Carnap and Wittgenstein (Gergely Ambrus). As usual, two reviews of recent publications in the philosophy of mathematics (Paolo Mancosu) and research on Otto Neurath's lifework (Jordi Cat/Adam Tuboly) are included as related research contributions. This book is of interest to students, historians, and philosophers dealing with the history of Austrian and German philosophy in the 19th and 20th century.

The volume deals with ontological and semantical issues concerning things, facts and events. Ontology tells us about what there is, whereas semantics provides answers to how we refer to what there is. Basic ontological categories are commonly accepted along with basic linguistic types, and linguistic types are accepted as basic if and because they refer to acknowledged ontological categories. In that sense, both disciplines are concerned with structure - the structure of the world and the structure of our language. An extended introduction overviews the topic as a whole, presenting in detail its history and the main contemporary approaches and discussions. More than 20 contributions by internationally acknowledged scholars make the volume a comprehensive study of some very fundamental philosophical entities.

This is a controversial collection of brand new papers by some outstanding philosophers and scholars. Its aim is to offer comprehensive theistic replies to the traditional arguments against the existence of God.

The Lvov-Warsaw School was one of the most important currents in the 20th-century analytical movement. Kazimierz Twardowski, a student Franz Brentano and a professor of philosophy in Lvov, was the founder and at the same time an outstanding representative of the School. The papers included into the volume present comprehensively Twardowski’s views and indicate what his lasting contribution to philosophy consists of.

Propositions are routinely invoked by philosophers, linguists, logicians, and other theorists engaged in the study of meaning, communication, and the mind. To investigate the nature of propositions is to investigate the very nature of our connection to each other, and to the world around us. As one of the only volumes of its kind, The Routledge Handbook of Propositions provides a comprehensive overview of the philosophy of propositions, from both historical and contemporary perspectives. Comprising 33 original chapters by an international team of scholars, the volume addresses both traditional and emerging questions concerning the nature of propositions, and our capacity to engage with them in thought and in communication. The chapters are clearly organized into the following three sections: I. Foundational Issues in the Theory of Propositions II. Historical Theories of Propositions III. Contemporary Theories of Propositions Essential reading for philosophers of language and mind, and for those working in neighboring areas, The Routledge Handbook of Propositions is suitable for upper-level undergraduate study, as well as graduate and professional research.

The claim according to which there is a categorial gap between meaning and saying – between what sentences mean and what we say by using them on particular occasions – has come to be widely regarded as being exclusively a claim in the philosophy of language. The present essay collection takes a different approach to these issues. It seeks to explore the ways in which that claim – as defended first by ordinary language philosophy and, more recently, by various contextualist projects – is grounded in considerations that transcend the philosophy of language. More specifically, the volume seeks to explore how that claim is inextricably linked to considerations about the nature of truth and representation. It is thus part of the objective of this volume to rethink the current way of framing the debates on these issues. By framing the debate in terms of an opposition between "ideal language theorists" and their semanticist heirs on the one hand and "communication theorists" and their contextualist heirs on the other, one brackets important controversies and risks obscuring the undoubtedly very real oppositions that exist between different currents of thought.
