Scholars from all the continents have written articles to celebrate the 70th 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).

Nicolai Hartmann's Possibility and Actuality is the second volume of a four-part investigation of ontology. It deals with such questions as: How do we know that something is really possible? Is the possible only the actual? Is the actual only the possible? What is the difference between ideal and real possibility? This groundbreaking work of modal analysis describes the logical relations between possibility, actuality, and necessity, and it provides insight into the relations between modes of knowledge and modes of being. Hartmann reviews the history of philosophical concepts of possibility and necessity, from ancient Megarian philosophy to Aristotle, to Medieval Scholasticism, to Leibniz, Kant, and Hegel. He explains the importance of modal analysis as a basic investigative tool, and he proposes an approach to understanding the nature of human existence that unifies the fields of ontology, modal logic, metaphysics, and epistemology. This brilliant and fascinating work is relevant to many topics of debate in contemporary philosophy, including the ontology of possible worlds, the metaphysics of modality, the logic of counterfactual conditionals, and modal epistemology. It illuminates the nature of real, ideal, logical, and epistemic possibility.

The belief is widely held that the physical world is causally-driven. The world is one because a tangled web of causally-driven processes keeps it together. However, both the psychological and the social worlds cannot be articulated in causal terms only. Hereby, "motivation" is used as the most general term referring to whatever keeps (synchronically) together and provides (diachronic) reasons explaining the behavior of psychological and social systems. In order to systematically address these problems, a categorical framework is needed for understanding the various types of realities populating the world and their multifarious interrelations. The papers collected in this volume dig into some of the intricacies presented by these problems. The papers here presented have been selected from those presented at the workshops bearing the very same name, "Causality and Motivation" organized in Bolzano and Rome.

Nicolai Hartmann was one of the most prolific and original, yet sober, clear and rigorous, 20th century German philosophers. Hartmann was brought up as a Neo-Kantian, but soon turned his back on Kantianism to become one of the most important proponents of ontological realism. He developed what he calls the "new ontology", on which relies a systematic opus dealing with all the main areas of philosophy. His work had major influences both in philosophy and in various scientific disciplines. The contributions collected in this volume from an international group of Hartmann scholars and philosophers explore subjects such as Hartmann's philosophical development from Neo-Kantianism to ontological realism, the difference between the way he and Heidegger overcame Neo-Kantianism, his Platonism concerning eternal objects and his interpretation of Plato, his Aristotelianism, his theoretical relation to Wolff's ontology and Meinong's theory of objects, his treatment and use of the aporematic method, his metaphysics, his ethics and theory of values, his philosophy of mind, his philosophy of mathematics, as well as the influence he had on 20th century philosophical anthropology and biology.

The imposing scope and penetrating insights of German philosopher Nicolai Hartmann's work have received renewed interest in recent years. The Neo-Kantian turned ontological realist established a philosophical approach unique among his peers, and it provides a wealth of resources for considering contemporary philosophical problems. The chapters included in this volume examine his ethics, ontology, aesthetics, philosophy of mind, and philosophy of nature. They explore his ontology of values, autonomy and human enhancement, and law; his theory of levels of reality, space-time and geometry, the categories of temporality, causality, and "life," the question of realism, and social ontology. Others take inspiration from his aesthetic theory, ideas about education, and his embrace of the Socratic pathos of wonder. They bring his philosophy into conversation with that of his contemporaries, including Roman Ingarden and Konrad Lorenz's appropriation of Hartmann, as well as with the history of philosophy, including Plato's theory of recollection, pre-Socratic philosophy, and that of his Russian teacher Nikolai Lossky. Those familiar with Hartmann's wide-ranging systematic philosophy will benefit from these new engagements with his work, and those new to it will find them relevant to a number of current philosophical debates.

This volume presents a selection of the Proceedings of the Workshop on Anticipation, Agency and Complexity held in Trento (Italy) on April 2017. The contributions contained in the book brilliantly revolve around three core concepts: agency, complexity and anticipation, giving precious insights to further define the discipline of anticipation. In a world that moves increasingly fast, constantly on the verge of disruptive events, more and more scholars and practitioners in any field feel in need of new approaches to make sense of the complexity and uncertainty that the future seems to bear. The theory of anticipation tries to describe how possible futures are intrinsically intertwined with the present.

In his forthcoming book, Roberto Poli presents original discoveries that have generated ground-breaking insights based on years of research and performance: long-standing interpretations of commonly encountered musical signs and symbols, from as early as the 1770s, may fail to reveal the composers' intended meanings. These misconstrued readings are due precisely to traditions themselves - traditions that have rested largely upon received knowledge rather than historical accuracy. Restoring the original connotation of signs and symbols in the scores can bring us closer to practices that have not gained access to our vocabulary because of decades of misinformed playing and fallacious scholarship. By bringing us closer to intended practices, the restoration of these meanings can give us greater interpretive insight and freedom.

Ontology was once understood to be the philosophical inquiry into the structure of reality: the analysis and categorization of 'what there is'. Recently, however, a field called 'ontology' has become part of the rapidly growing research industry in information technology. The two fields have more in common than just their name.
Theory and Applications of Ontology is a two-volume anthology that aims to further an informed discussion about the relationship between ontology in philosophy and ontology in information technology. It fills an important lacuna in cutting-edge research on ontology in both fields, supplying stage-setting overview articles on history and method, presenting directions of current research in either field, and highlighting areas of productive interdisciplinary contact.
Theory and Applications of Ontology: Computer Applications presents ontology in ways that philosophers are not likely to find elsewhere. The volume offers an overview of current research in ontology, distinguishing basic conceptual issues, domain applications, general frameworks, and mathematical formalisms. It introduces the reader to current research on frameworks and applications in information technology in ways that are sure to invite reflection and constructive responses from ontologists in philosophy.
