Discussions about abstraction are so important and so profound that this topic can hardly be neglected. It has inevitably cropped up again in various periods of philosophical enquiry. Despite these ancient roots and after the great debate that characterised the empirical and rationalistic tradition, interest in the problem has unfortunately been absent in large measure from the mainstream of mathematical logic and analytic philosophy. It seems that there is a gap between the epistemological theorization, in which it is difficult to find new insights on the problem of abstraction, and the historical studies concerning the development of philosophical thought. Such studies, however, present a more fertile ground for such insights. Here the reader will find presented for the first time a collection of papers about the topic, considered from an historical point of view together with an awareness of the need for building a bridge between historical research and theoretical speculation. Accordingly the volume consists of both general overviews which sketch the signifcance and the fortunes of abstraction in science, philosophy and logic (the first part) and historical case studies which focus on abstraction in particular thinkers (the second part). This volume is of interest for both general philosophers and historians of philosophy.

The principal task of the book series Poznan Studies in the Philosophy of the Sciences and the Humanities is to promote those developments in philosophy that respect the tradition of great philosophical ideas, on the one hand, and the manner of philosophical thinking introduced by analytical philosophy, on the other. The aim is to contribute to practicing philosophy as deep as Marxism and as caring about justification as positivism.

Idealization XIV: Models in Science offers a detailed ontological, epistemological and historical account of the role of models in scientific practice. The volume contains contributions of different international scholars who developed many aspects of the use of idealizations and models both in the natural and the social sciences. This volume is particularly relevant because it offers original contributions concerning one of the main topic in philosophy of science: the role of models in such branches of the sciences and the humanities like comparative historical sociology, economics, history, linguistics and political philosophy. Contributors are: Giacomo Borbone, Krzysztof Brzechczyn, Mieszko Ciesielski, Adam Czerniak, Xavier de Donato Rodríguez, José L. Falguera, Adolfo García de la Sienra, Lidia Godek, Igor Hanzel, Łukasz Hardt, Krzysztof Kiedrowski, Barbara Konat, Zenonas Norkus, Piotr Przybysz, Piotr Szwochert

This book deals with the fundamental semantics of images of Europe, which consist of valences, mirror beliefs and affectivities. This is why it relaunches the importance of the European discourse in its symbolic dimension. As such, it explores the many images of Europe, or rather the many images through which European discourse is actually constituted in daily life, in search of their enunciative responsibility in today’s world for determining the current “State of the Union”. The identity of the European continent is based on a millenary tension between universalism and particularism: images of Europe have in fact been alternately inspired, over the centuries, by a model of homogeneity – Roman and Carolingian imperial disposition – on the one hand, and by a model of fragmentation – a Europe of city-states, municipalities, regions and small fatherlands – on the other. In the European Union, a political and economic organism, this issue has recently been amplified to the point that it has reentered public debate, and political parties that are only recognizable for being Europeanists or anti-Europeanists are now ubiquitous. In this regard, one major bone of contention is how to portray the quintessential aspects of the European territory, which are either interpreted as “thresholds” to be overcome in the name of a model of United Europe – “integral totality” – or are instead regarded as insurmountable obstacles for a Europe that is irreparably and perhaps, according to anti-Europeanists, fortunately fragmented – “partitive totality”. Further, this is to be done without excluding the possibility of contradictory and complementary solutions to these binary visions. In this context the book analyzes various texts in order to obtain a more precise picture of the clash, reveal its semiotic forms, and by doing so, identify a way out of the crisis.

This book investigates Aristotle’s views on abstraction and explores how he uses it. In this work, the author follows Aristotle in focusing on the scientific detail first and then approaches the metaphysical claims, and so creates a reconstructed theory that explains many puzzles of Aristotle’s thought. Understanding the details of his theory of relations and abstraction further illuminates his theory of universals. Some of the features of Aristotle’s theory of abstraction developed in this book include: abstraction is a relation; perception and knowledge are types of abstraction; the objects generated by abstractions are relata which can serve as subjects in their own right, whereupon they can appear as items in other categories. The author goes on to look at how Aristotle distinguishes the concrete from the abstract paronym, how induction is a type of abstraction which typically moves from the perceived individuals to universals and how Aristotle’s metaphysical vocabulary is "relational.’ Beyond those features, this work also looks at how of universals, accidents, forms, causes and potentialities have being only as abstract aspects of individual substances. An individual substance is identical to its essence; the essence has universal features but is the singularity making the individual substance what it is. These theories are expounded within this book. One main attraction in working out the details of Aristotle’s views on abstraction lies in understanding his metaphysics of universals as abstract objects. This work reclaims past ground as the main philosophical tradition of abstraction has been ignored in recent times. It gives a modern version of the medieval doctrine of the threefold distinction of essence, made famous by the Islamic philosopher, Avicenna.

Recent economic and financial crises have exposed mainstream economics to severe criticism, bringing present research and teaching styles into question. Building on a solid and vivid tradition of economic thought, this book challenges conventional thinking in the field of economics. The authors turn to the work of Luigi Pasinetti, who proposed a list of nine methodological and theoretical ideas that characterize the Classical Keynesian School. Drawing inspiration from both Keynes and Sraffa, this school has forged a long-standing and ambitious research programme often advocated as a competing paradigm to mainstream economics. Overall, the Classical Keynesian School provides a comprehensive analytical framework into which most non-mainstream schools of thought can be integrated. In this collection, a group of leading scholars critically assess the nine main ideas that, in Pasinetti's view, characterize the Classical-Keynesian approach, evaluating their relevance for both the history of economics and for present economic research.
