The volume aims to show the variety of research currents of the Lvov-Warsaw School and the ways in which these currents are developed today. The content of the book is divided into three parts: “Logic and Semiotics”, “Metaphysics and Ontology”, and “Psychology and Sociology”.

In _Kazimierz Twardowski: A Grammar for Philosophy_ Maria van der Schaar shows the importance of Twardowski’s method, his philosophical grammar, for both the Lvov-Warsaw School, and analytic philosophy today.

This study is a revised version ofa book, published in February 1990 under the same title, as my Ph.D. thesis at the University of Stockholm. Revision of an earlier work poses specific problems, some of which deserve mentioning. After the appearance of the first version of this book new literature on related subjects and a new version of the principal HusserI text involved in the discussion have appeared. The newer literature contains both accounts of Twardowski's thought and its relations to (...) HusserI's philosophy, though without referring to my study from 1990, largely because the texts concerned were con ceived parallell to it, though published later, or independently of it. It would seem anachronistic, in this situation, to enter into new and ex tensive discussions with the authors of this literature. The choice made here has been to update the original study, adding references to texts published after my study, and to take account of points of views expressed. I have retained the major part of the basic information giv en in the 1990 version, although some of it might now be more famil iar to interested students than it was in 1990. (shrink)

The volume contains almost thirty papers by Kazimierz Twardowski , the founder of the Lvov-Warsaw School. The papers are published in English for the first time. The papers concern fundamental problems of philosophy: the methods of philosophizing, the boundary of psychology and semiotics, the conceptual apparatus of metaphysics, ethical skepticism, the question of free will and ethical obligation, the aesthetics of music and so on. The systematic considerations are complemented by concise but excellent sketches of the philosophical views of Socrates, (...) Aquinas, Leibniz, Spencer, Nietzsche, and Bergson. (shrink)

The purpose of this book is to highlight Carl Stumpf's contributions to philosophy and to assess some of the aspects of his work. This book brings together several specialists of Stumpf and the school of Franz Brentano, and includes fourteen original studies (in English and German) on the various aspects of Stumpf's philosophy, and some of his unpublished writings. This book is divided into four sections, and also includes a general introduction on the reception and actuality of Stumpf's philosophy. The (...) first section examines the historical sources of his philosophy, the second examines some of the central themes of his work and the third examines his relationship to other philosophers. The fourth section consists of notes taken by Husserl during Stumpf's lectures on metaphysics in Halle, Stumpf's introduction to the edition of his correspondence with Brentano, which he prepared in 1929, and some important letters pertaining to this correspondence. This book also provides a comprehensive bibliography of Stumpf's works. (shrink)

Unlike the first English translation in 1974, this edition contains the text corresponding to Brentano's original 1874 edition.

This study aims to account for the reception of the philosophy of Carl Stumpf since the turn of the twenty-first century and to emphasize the actuality of some of the aspects of his philosophy. The present text is subdivided into several sections, each corresponding to one of the main topics discussed in the recent literature on the work of Stumpf. In the first section, I try to show, using his classification of sciences, that Stumpf's empirical work is driven by a (...) unitary philosophical program. I then examine the ramifications of this program in several areas of philosophy that have been the subject of recent commentaries and publications. I begin with the commentaries on the recent publication of Stumpf's thesis on mathematical axioms, which stress Stumpf's contribution to the philosophy of mathematics and to theory of knowledge, and more specifically to the debate on logical psychologism that Frege and Husserl will address a few years later. I conclude this section by examining the second of two major themes in the work of Stumpf that have been the subject of several recent studies, namely, on the one hand, logic and the nature of states of affairs and, on the other hand, Stumpf's contribution to the mind-body problem and to the topic of relations. The third section is divided into two parts. In the first one, I try to briefly account for the vast literature on Stumpf's contribution to psychology understood broadly enough as to include his work on the psychology of sound, Gestalt psychology, animal psychology and the psychology of child development. I provide, in the second part of this section, a summary of his studies in the area of aesthetics and musicology in general, i.e. his contribution to the history of music and its origins, to ethnomusicology, and to acoustics. Although this study does not aim at being exhaustive, it provides an overview of the important aspects of Stumpf's contribution to philosophy. (shrink)
