A conjecture on the metaphysical nature of Tractatus objects is put forward and its interpretative adequacy is tested. The clarification of the true import of the metaphor of logical space and the recognition of the theoretical role played by Wittgenstein's explicit claim that the emptiness of logical space is conceivable enable us to account for the thesis that objects are the substance of the world. Once objects are identified with those universal abstract entities which are qualia, and complexes or states (...) of affairs with their concrete instances, some statements of the Tractatus become liable to a consistent reading: that objects are colourless ; that space, time and colour are forms of objects ; that Leibniz's Principle of the Identity of Indiscernibles, though still holding for complexes, does not apply to objects . Lastly, it is shown how the interpretation of objects as qualia sheds a vivid light on the theme of the relation between objects and time. (shrink)

On the basis of an analysis of the relevant parts of Tractatus logico-philosophicus, a definition of the property of saying something, and of the obviously correlated property of saying nothing, is given. By applying that definition, both tautologies and contradictions are sanctioned as saying nothing, as lacking sense, in full agreement with Wittgenstein's explicit statements. On the other hand, a recent systematic attempt by A. Negro to extract from the Tractatus a criterion for sense containment and a criterion for saying (...) more, that is, for comparing the amount of sense of propositions, leads to the conclusion that the sense of any proposition is contained in the sense of a contradiction and that contradictions say more than any other propositions. The problem faced in this paper is that of restoring consistency between Negro's criteria, which on the whole give a correct interpretation of the text of the Tractatus, and Wittgenstein's thesis that, not only tautologies, but also contradictions say nothing.

Wittgenstein's role was vital in establishing mathematics as one of this century's principal areas of philosophic inquiry. In this book, the three phases of Wittgenstein's reflections on mathematics are viewed as a progressive whole, rather than as separate entities. Frascolla builds up a systematic construction of Wittgenstein's representation of the role of arithmetic in the theory of logical operations. He also presents a new interpretation of Wittgenstein's rule-following considerations - the `community view of internal relations'.

CAUSES AND REASONS: EXPLICATIVE MODELS IN NATURAL AND HUMAN SCIENCES Starting from Wittgenstein’s distinction between causes and reasons of an action, the paper presents two influential models in the methodology of explanation: the deductive‐nomological model elaborated by C. G. Hempel and the model based on Aristotle’s practical syllogism, in G. H. von Wright’s version. The controversy between methodological monism and methodological dualism, which has its roots in the opposition between explaining and understanding, is examined.

Understanding Wittgenstein's Tractatus provides an accessible and yet novel discussion of all the major themes of the Tractatus. The book starts by setting out the history and structure of the Tractatus. It then investigates the two main dimensions of the early Wittgenstein's thought, corresponding to the division between what language can say by means of its propositions and what language can only show. It goes on to discuss picture theory, logical atomism, extensionality, truth-functions and truth-operations, semantics, metalogic and mathematics, solipsism (...) and value, metaphysics, and finally, Wittgenstein's idea of the duty of maintaining silence. Frascolla also proposes a new interpretation of the ontology of the Tractatus. Based on the identification of objects with qualia, the argument put forward in the book challenges the currently prevalent ideas of the ‘New Wittgenstein'. The paradoxical nature of the Tractatus itself, and the theme of "throwing away the ladder", are thus revisited in a new key. _Understanding Wittgenstein's Tractatus_ is essential reading for anyone wishing to further their insight into one of the most influential works of twentieth-century philosophy.

The philosophy of arithmetic of Wittgenstein's Tractatus is outlined and the central role played in it by the general notion of operation is pointed out. Following which, the language, the axioms and the rules of a formal theory of operations, extracted from the Tractatus, are presented and a theorem of interpretability of the equational fragment of Peano's Arithmetic into such a formal theory is proven.

In the first paragraph, the focus is on the early Wittgenstein's conception of truth: the Disquotational Schema is shown to be derivable from the semantic and ontological principles of the picture theory. Then, the article scrutinises the way the Disquotational Schema provides the basis for what the later Wittgenstein takes as a philosophically appropriate description of the practice of making assertions. The general abstract notion of truth makes room for a situated notion of warranted assertibility as the key-notion. Last, the (...) issue of how Wright's Argument from Informational Neutrality could be neutralised from the later Wittgenstein's viewpoint is dealt with. (shrink)

On the Exceptionality of Philosophy: Is There Discontinuity between Philosophy and Science? The article is devoted to a short presentation of the controversy between the meta-philosophical conception of the nature of philosophy and its relation with natural science known as exceptionalism, and the opposite anti-exceptionalist conception. The exceptionalist view is traced back to the linguistic turn and is illustrated by focusing on the early and intermediate Wittgenstein, Waismann and Schlick. Quine’s naturalism is identified as the background of the anti-exceptionalist view, (...) whose developments in the area of analytic metaphysics are taken as paradigmatic. Some issues concerning anti-exceptionalism are raised. (shrink)

SCIENCE, PHILOSOPHY, COMMON SENSE: HOW THE EXTRAORDINARY COULD TURN INTO THE OBVIOUS The paper is devoted to an examination of some aspects of the relation between science, philosophy and common sense. By referring to crucial episodes of the history of astronomy and physics such as the Copernican Revolution and the birth of Relativity Theory, attention is paid to the process by which new scientific ideas contrasting with deeply entrenched intuitions and socially shared beliefs are gradually absorbed into the conceptual schema (...) underlying common sense. Some light is thrown on the role that philosophy can play in that process. (shrink)

1 Qualche considerazione preliminare È opportuno cominciare citando per intero la sezione 5.1362 del Tractatus, attorno alla quale ruoterà gran parte di ciò che andrò sostenendo: Il libero arbitrio consiste nell’impossibilità di conoscere ora azioni future. Noi le potremmo conoscere solo se la causalità fosse una necessità interiore, come quella della conclusione logica. — La connessione di conoscere e conosciuto è quella della necessità logica. (“A sa che p" è priva di senso, se p è una taut...

Wittgenstein's conceptions considered, from a more general point of view not only classic positions in philosophy of mathematics such as formalism, but the controversy between realism and antirealism as well. The treatment of arithmetic in the Tractatus Logico‐Philosophicus reveals a radically antirealist stance, where by “radical antirealism” which means a conception that deprives arithmetical propositions, identified with equations, of assertability and truth‐aptness, by construing them as expressions of rules of syntax, of rules dealing with signs. The Tractatus’ radical antirealism results (...) in a conception of mathematics that has remarkable points of contact with Hilbert's formalism, even though important qualifications will have to be added to that statement in order to make it minimally acceptable. In virtue of the characterization of the notion of a thought as the logical picture of states of affairs, a mathematical proposition, insofar as it does not express a thought, is not even the logical picture of a state of affairs.

Leading scholars discuss whether some of the main tenets or theses that are currently or traditionally ascribed to Wittgenstein are still both theoretically and exegetically viable, by focusing on three well-established Wittgensteinian themes: mind, meaning, and metaphilosophy.

Critica discussion of Pasquale Frascolla, Tractatus Logico-Philosophicus. Introduzione alla lettura, Carocci, Roma, 2000, 322 pp.

This is a critical review of Pasquale Frascolla's Tractatus Logico-Philosophicus. Introduzione alla lectura.

Born out of a major international dialogue held at the Fondazione Giorgio Cini in Venice, Italy, this collection of essays presents innovative and provocative arguments about the claims of universal knowledge schemes and the different aesthetic and material forms in which such claims have been made and executed. Contributors take a close look at everything from religious pilgrimages, museums, and maps of the world, to search engines and automated GPS. Current obsessions in information technology, communications theory, and digital culture often (...) concern the value and possibility of a grand accumulation of universally accessible forms of knowledge: total libraries, open data bases, ubiquitous computing, and 'smart' technologies. These obsessions have important social and philosophical origins, and they raise profound questions about the very nature of knowledge and its organization. This volume's contributors draw on the histories of maps and of encyclopedias, worldviews and visionary collections, to make sense of the crucial relation between the way the world is known and how it might be displayed and transformed.

The development of ideas in Thomas Aquinas's philosophical thinking has been the subject of numerous smaller studies, but no contemporary work in the English-speaking world covers his every single work in chronological order in terms of philosophical development, influences, manuscript evidence, and historical setting. In Thomas Aquinas: A Historical and Philosophical Profile, Pasquale Porro has provided a complete landscape of Thomas's corpus that will give Thomistic scholars and students an invaluable reference point for research, discussion, and debate.

Il volume si presenta come un manuale di riferimento sul pensiero di Umberto Galimberti, una miscellanea di studi cui ha contribuito un alto numero di studiosi di diverse discipline. Questo libro indaga il lungo arco del lavoro galimbertiano: dal pensiero simbolico, dalla fenomenologia alla psichiatria, fino ad approdare alla riflessione sull'età della tecnica e alla consulenza filosofica.
