The central idea developed by the contributions to this book is that the split between analytic philosophy and phenomenology - perhaps the most impor­ tant schism in twentieth-century philosophy - resulted from a radicalization of reciprocal partialities. Both schools of thought share, in fact, the same cultural background and their same initial stimulus in the thought of Franz Brentano. And one outcome of the subsequent rift between them was the oblivion into which the figure and thought of Brentano have fallen. The first step to take in remedying this split is to return to Brentano and to reconstruct the 'map' of Brent ani sm. The second task (which has been addressed by this book) is to revive inter­ est in the theoretical complexity of Brentano' s thought and of his pupils and to revitalize those aspects that have been neglected by subsequent debate within the various movements of Brentanian inspiration. We have accordingly decided to organize the book into two introductory es­ says followed by two sections (Parts 1 and 2) which systematically examine Brentano's thought and that of his followers. The two introductory essays re­ construct the reasons for the 'invisibility', so to speak, of Brentano and set out of his philosophical doctrine. Part 1 of the book then ex­ the essential features amines six of Brentano's most outstanding pupils (Marty, Stumpf, Meinong, Ehrenfels, Husserl and Twardowski). Part 2 contains nine essays concentrating on the principal topics addressed by the Brentanians.

Formal ontology combines two ideas, one originating with Husserl, the other with Frege: that of ontology of the formal aspects of all objects, irrespective of their particular nature, and ontology pursued by employing the tools of modern formal disciplines, notably logic and semantics. These two traditions have converged in recent years and this is the first collection to encompass them as a whole in a single volume. It assembles essays from authors around the world already widely known for their work in formal ontology, and illustrates that through the application of formal methods the ancient discipline of ontology may be put on a firm methodological basis. The essays not only illuminate the nature of ontology and its relation to other areas, in language, logic and everyday life, but also demonstrate that common issues from the analytical and phenomenological traditions may be discussed without ideological barriers. Audience: advanced students of and specialists in philosophy, linguistics, cognitive science, computer science, database engineering.

Scholars from all the continents have written articles to celebrate the seventieth birthday of Jan Srzednicki, a thinker still at the height of his powers.Srzednicki's scientific work alternates between problems of Austrian and German philosophy and questions of political philosophy. The papers published in this volume discuss topics of general philosophy, in the clear and deep style both of Srzednicki's own philosophical work and of the authors investigated in his writings (mainly Brentano and the Polish tradition of analytic philosophy). The topics developed pertain to the fields of epistemology (common sense, knowledge and objectivity, truth and perception) and of logic and philosophy of logic (paraconsistent logic, definition and duality).
