The Anthropocene is seen by many scholars across the sciences and the humanities as a tool for political action. Yet the validation process for this term appears to be extremely conservative. According to geologists’ leading efforts to formalize the term, signals need to petrify in stratigraphic sequences in order to become candidates to mark the start of the Anthropocene. I argue that this emphasis results from a fossilized view of becoming, where time is seen as a punctuated accumulation of solid (...) surfaces that are accessible only in retrospect. I show that this petrified view of change relates to a tendency to divorce earth and sky, which currently divides the practices of humanities scholars and geologists, as well as those of earth system scientists and stratigraphers collaborating on the formalization of the Anthropocene. Challenging this tendency, I conclude, requires opening up earth’s history to the more-than-solid flows of environmental change. (shrink)

The essays in this volume, written by well-known economists and other social scientists from North America, Europe and Australia, share to an unusual degree a common concern with the competitive mechanisms that underlie collective decisions and with the way they are embedded in institutional settings. This gives the book a unitary inspiration whose value is clear from the understanding and insights its chapters provide on important theoretical and practical issues such as the social dimension and impact of trust, the management (...) of information in bureaucratic settings, the role of political parties in constitutional evolution, inter-level rivalry and reassignments of powers in federal and unitary systems of government, the impact of ethnicity and nationalism on federal institutions or arrangements, and the response of governments and overarching institutions of globalization. The essays were written in honour of Albert Breton, a pioneer in this field of investigation. (shrink)

Available from UMI in association with The British Library. Requires signed TDF. ;The central position defended in this work is that Analytical philosophy is the best realization so far of Descartes' concern for the construction of a method of scientific investigation in philosophy. ;In Frege, the father of Analytical philosophy, such concern was embodied in his Conceptual Notation, which should have provided philosophy with a rigorous and powerful deductive system, and in the 'linguistic turn', i.e. the study of the structure (...) of thought conducted by means of an analysis of the structure of language. This 'linguistic turn' should have produced, in Frege's view, definitive conclusions about the limits of what is thinkable not by setting up arbitrary systems of Pure Reason, but through the controllable investigation of the logical structure of an entity--language--of which we have conceptual experience. ;Wittgenstein's later philosophy is seen here as an attack against the aims and tenets of Analytical philosophy. In fact, what Wittgenstein shows in Philosophical Investigations is, among other things, that by means of an investigation of language it is impossible to justify the assumption that language is an expression of thought. But, if this were true, it would follow that we were not justified in assuming that there exists an isomorphism between language and thought. That there is such an isomorphism is the presupposition which lies at the basis of Frege's 'linguistic turn'. ;In conclusion I attempt to prove that there is no solution to Wittgenstein's objections unless the original exclusively linguistic Analytical philosophy model is modified by a 'pragmatic turn'. The key element of the 'pragmatic turn' is that the truth of certain assumptions--and therefore the justification for their introduction--can be confirmed by the impact that the system based on them has on reality in controlling and transforming it successfully through techniques which are logically dependent on the system.

We reconsider the pragmatic interpretation of intuitionistic logic [21] regarded as a logic of assertions and their justi cations and its relations with classical logic. We recall an extension of this approach to a logic dealing with assertions and obligations, related by a notion of causal implication [14, 45]. We focus on the extension to co-intuitionistic logic, seen as a logic of hypotheses [8, 9, 13] and on polarized bi-intuitionistic logic as a logic of assertions and conjectures: looking at the (...) S4 modal translation, we give a de nition of a system AHL of bi-intuitionistic logic that correctly represents the duality between intuitionistic and co-intuitionistic logic, correcting a mistake in previous work [7, 10]. A computational interpretation of cointuitionism as a distributed calculus of coroutines is then used to give an operational interpretation of subtraction.Work on linear co-intuitionism is then recalled, a linear calculus of co-intuitionistic coroutines is de ned and a probabilistic interpretation of linear co-intuitionism is given as in [9]. Also we remark that by extending the language of intuitionistic logic we can express the notion of expectation, an assertion that in all situations the truth of p is possible and that in a logic of expectations the law of double negation holds. Similarly, extending co-intuitionistic logic, we can express the notion of conjecture that p, de ned as a hypothesis that in some situation the truth of p is epistemically necessary. (shrink)

Despite society’s increasing sensitivity toward green production, companies often struggle to find effective communication strategies that induce consumers to buy green products or engage in other environmentally friendly behaviors. To add clarity to this situation, we investigated the effectiveness of negative versus positive message framing in promoting green products, whereby companies highlight the detrimental versus beneficial environmental consequences of choosing less versus more green options, respectively. Across four experiments, we show that negatively framed messages are more effective than positively framed (...) ones in prompting consumers to engage in pro-environmental behaviors. More importantly, we find that anticipated shame is the emotion responsible for this effect. Furthermore, both environmental concern and the type of product promoted serve as moderators; thus, the mediating role of anticipated shame is attenuated when environmental concern is low and the product is a luxury one. Finally, we discuss the theoretical and managerial implications of our work, along with its limitations and some directions for future research. (shrink)

"We detail Abramsky's 'proofs-as-processes" paradigm for interpreting classical linear logic (CCL) [11] into a 'synchronous' version of the [pi]-calculus recently proposed by Milner [24]. The translation is given at the abstract level of proof structures. We give a detailed treatment of information flow in proof-nets and show how to mirror various evaluation strategies for proof normalization. We also give Soundness and Completeness results for the process-calculus translations of various fragments of CLL. The paper also gives a self-contained introduction to some (...) of the deeper proof-theory of CLL, and its process interpretation.". (shrink)

We consider a “polarized” version of bi-intuitionistic logic [5, 2, 6, 4] as a logic of assertions and hypotheses and show that it supports a “rich proof theory” and an interesting categorical interpretation, unlike the standard approach of C. Rauszer’s Heyting-Brouwer logic [28, 29], whose categorical models are all partial orders by Crolard’s theorem [8]. We show that P.A. Melliès notion of chirality [21, 22] appears as the right mathematical representation of the mirror symmetry between the intuitionistic and co-intuitionistc sides (...) of polarized bi-intuitionism. Philosophically, we extend Dalla Pozza and Garola’s pragmatic interpretation of intuitionism as a logic of assertions [10] to bi-intuitionism as a logic of assertions and hypotheses. We focus on the logical role of illocutionary forces and justification conditions in order to provide “intended interpretations” of logical systems that classify inferential uses in natural language and remain acceptable from an intuitionistic point of view. Although Dalla Pozza and Garola originally provide a constructive interpretation of intuitionism in a classical setting, we claim that some conceptual refinements suffice to make their “pragmatic interpretation” a bona fide representation of intuitionism. We sketch a meaning-asuse interpretation of co-intuitionism that seems to fulfil the requirements of Dummett and Prawitz’s justificationist approach. We extend the Brouwer-Heyting-Kolmogorov interpretation to bi-intuitionism by regarding co-intuitionistic formulas as types of the evidence for them: if conclusive evidence is needed to justify assertions, only a scintilla of evidence suffices to justify hypotheses.

Different phases of the restoration of Michelangelo's Sistine Chapel frescoes are discussed, including the techniques used to remove foreign matter deposited or applied in the course of time. Huge scientific and technical support is used for this project in contrast to the age?old operations of previous restorers and the simplicity of their equipment.

This essay explores the connection between post-truth and fear, arguing that the latter may be used as a tool to control information and thus manipulate public opinion. Furthermore, it discusses the role of law in regulating post-truth (among others, by a better regulation of Information Society providers). Eventually, some solutions are proposed.

The present collection of essays aims at casting light on important elements of Wittgenstein's thought and intellectual development. Some of Wittgenstein's ideas are here discussed using the «Tractatus» as a frame of reference, others by relating them to the views of G. Frege, G.E.M. Anscombe and D. Davidson.

Uno studio filosofico sull’etica è sempre di grande attualità. E in questo «dappertutto vi circola la passione per la verità e per il bene» (dalla Presentazione di Carmelo Vigna). Mai come oggi si parla di salute e di benessere, probabilmente perché si percepisce la mancanza di entrambi. In Occidente è così. L’etica si affaccia alla riflessione umana rivestita con i panni di un’etica filosofica, prima ancora che ulteriormente aggettivata, essendo una terminologia che rimanda, come è risaputo, ad Aristotele. Con «etica» (...) si intende oggi quel confine oltre cui non si può più andare, discutere, transigere, indagare: per questo – e correttamente – si parla rispettivamente di «confini etici», «indole etica » o non, «bioetica», «decisione etica», «comportamento etico» e così via. In qualche modo con «etica» si intende ciò che si impone ancor più della scienza o della decisione democratica. L’«etica» pone in questione il baluardo sollevato proprio da queste ultime due. Sanando la questione. Il modo, talvolta, sfugge, diventando, così, ambito proprio della filosofia e della sua visione interale. Questa è esattamente l’etica filosofica. Questo libro affronta temi di grande importanza e fascinosi, quali il bene, il male, la bontà, la crudeltà, la ragione, il sentimento, il «senso morale», la coscienza, la responsabilità, la Stato e la nazione.

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.

In higher-level cognitive tasks, older compared to younger adults show a bias towards positive emotion information and away from negative information (a positivity effect). It is unclear whether this effect occurs in early perceptual processing. This issue is important for determining if the positivity effect is due to automatic rather than controlled processing. We tested this with older and younger adults on a positive/negative face emotion valence classification task using masked priming. Positive (happy) and negative (angry) face targets were preceded (...) by masked repetition or valence primes with neutral face baselines. In Experiment 1, 30 younger and 30 older adults were tested with 50 ms primes. Younger adults showed repetition priming for both positive and negative targets. Older adults showed repetition priming for positive but not negative targets. Neither group showed valence priming. In Experiment 2, 30 older and 29 younger adults were tested with longer duration primes. Younger adults showed repetition priming for both positive and negative emotions, and no valence priming. Older adults only showed repetition and valence priming for positive targets. We proposed older adults’ lack of angry face priming was due to an early attention orienting strategy favouring happy expressions at the expense of angry ones. (shrink)

This book contains seminal discussions of central issues in the philosophy of language, mathematics, mind, religion and time. Is common language conceptually prior to idiolectics? What is a theory of meaning? Does constructivism provide a satisfactory account of mathematics? What are indefinitely extensible concepts? Can we change the past? These are only some of the very important questions addressed here. Both the papers written by the contributors and Dummett's replies provide a great wealth of stimulating ideas for those who currently (...) do research in the respective areas touched upon without making the reading exceedingly tedious. This feature, common to most of the papers in this book, makes it possible to use the material presented in undergraduate courses at university level. (shrink)

This edited collection casts light on central issues within contemporary philosophy of mathematics such as the realism/anti-realism dispute; the relationship between logic and metaphysics; and the question of whether mathematics is a science of objects or structures. The discussions offered in the papers involve an in-depth investigation of, among other things, the notions of mathematical truth, proof, and grounding; and, often, a special emphasis is placed on considerations relating to mathematical practice. A distinguishing feature of the book is the multicultural (...) nature of the community that has produced it. Philosophers, logicians, and mathematicians have all contributed high-quality articles which will prove valuable to researchers and students alike. (shrink)

Bertrand Russell's contributions to last century's philosophy and, in particular, to the philosophy of mathematics cannot be overestimated.Russell, besides being, with Frege and G.E. Moore, one of the founding fathers of analytical philosophy, played a major rôle in the development of logicism, one of the oldest and most resilient1 programmes in the foundations of mathematics.Among his many achievements, we need to mention the discovery of the paradox that bears his name and the identification of its logical nature; the generalization to (...) the whole of mathematics of Frege's idea that it is not possible to draw a demarcation line between logic and arithmetic; the programme, carried out with Whitehead, of derivation of mathematics from the logical system of Principia Mathematica ; and the ramified theory of types, devised by Russell to protect the system of PM from the known paradoxes.Although there is an ample literature on these topics, it is quite important to reconsider Russell's contributions to the foundations of mathematics at a time when, as a consequence of the crisis of the classical programmes in the foundations of mathematics, new trends are beginning to develop within the philosophy of mathematics. These are trends which move in a very different direction from that of logicism, intuitionism, and Hilbert's programme.To see this we need to consider that, in spite of profound disagreements on the nature of mathematical activity, on the relationship existing between logic and mathematics, on the causes of and therapies for the paradoxes, etc., logicism, intuitionism, and Hilbert's programme share an important metaphor: the idea that mathematics is an edifice built on unshakable foundations,2 an edifice which makes possible only a cumulative growth of mathematical knowledge.Such a metaphor—which, together with more specific theses belonging to these schools of thought, remained unsupported ….
