Adjectives can be gradable or non-gradable and this aspect of their meaning is responsible for their different distribution and also for their classification into two different classes of antonyms. Non-gradable antonyms are called contradictories: they are neither true nor false together and exclude any middle term; gradable antonyms are called contraries: they are not simultaneously true, but may be simultaneously false. While with contraries a negative disjunction (neque...neque) can define an intermediate level, with contradictories it simply means that either term (...) of the disjunction is excluded. There are however some Latin examples, such as neque vivus neque mortuus (`neither alive nor dead'), where the negation of a contradictory pair is used to convey a third, intermediate value. This third possibility is precisely what gives place to a paradox. Such an intermediate level can be defined also by terms like semivivus, semianimis (`half-dead'). Following Ducrot's theory on argumentation, such terms represent an argumentative attenuation, not with respect to life, rather with respect to death. With contradictories, in fact, the use of semi-, like the use of negation, gives the assertion of the opposite term as a result. (shrink)
This book considers the semantic and syntactic nature of indexicals - linguistic expressions, as in I, you, this, that, yesterday, tomorrow , whose reference shifts from utterance to utterance.There is a long-standing controversy as to whether the semantic reference point is already present as syntactic material or whether it is introduced post-syntactically by semantic rules of interpretation. Alessandra Giorgi resolves this controversy through an empirically grounded exploration of temporal indexicality, arguing that the speaker's temporal location is specified in the (...) syntactic structure. She supports her analysis with theoretical and empirical arguments based on data from English, Italian, Chinese, and Romanian. Professor Giorgi addresses some difficult and longstanding issues in the analysis of temporal phenomena - including the Italian imperfect indicative, the properties of the so-called future-in-the-past, and the properties of Free Indirect Discourse - and shows that her framework can account elegantly for all of them. Carefully argued, succinct, and clearly written her book will appeal widely to semanticists in linguistics and philosophy from graduate level upwards and to linguists interested in the syntax-semantics interface.

Traditional accounts of perception endorse an input–output model: perception is the input from world to mind and action is the output from mind to world. In contrast, enactive accounts propose action to be constitutive of perception. We focus on Noë's sensorimotor version of enactivism, with the aim of clarifying the proper limits of enactivism more generally. Having explained Noë's particular version of enactivism, which accounts for the contents of perceptual experience in terms of sensorimotor knowledge, we use taste as a (...) test for his central thesis. We conclude that taste and other similar senses do not display the central features which Noë claims apply to all perceptual experience. (shrink)
In this paper I offer an innovative interpretation of Nietzsche's metaethical theory of value which shows him to be a kind of constitutivist. For Nietzsche, I argue, valuing is a conative attitude which institutes values, rather than tracking what is independently of value. What is characteristic of those acts of willing which institute values is that they are owned or authored. Nietzsche makes this point using the vocabulary of self-mastery. One crucial feature of those who have achieved this feat, and (...) have consequently become agents, is that they possess a diachronic or long will and are consequently capable of the rational governance of future behaviour. The possession of a will of this sort is crucial because it is a necessary condition for engaging in temporally unified activities which are a requisite of authorship. Nietzsche, I argue, makes these points in his doctrine of eternal recurrence which provides a test that acts of will must pass to count as laws. In the final section of the paper I argue for the superiority of this interpretation over some of its competitors. (shrink)
Empathy is the phenomenal experience of mirroring ourselves into others. It can be explained in terms of simulations of actions, sensations, and emotions which constitute a shared manifold for intersubjectivity. Simulation, in turn, can be sustained at the subpersonal level by a series of neural mirror matching systems.
In their excellent book The Phenomenological Mind Shaun Gallagher and Dan Zahavi demonstrate that analytic philosophy of mind and cognitive science have much to learn from work conducted in the phenomenological tradition. In particular, they show how discussions about embodied cognition, about the self, and about mind-reading could be greatly enhanced if the lessons of phenomenology were heeded to. However, their discussion of the structure of intentionality is, in my view, less successful in this regard.
After more than three centuries, Molyneux's question continues to challenge our understanding of cognition and perceptual systems. Locke, the original recipient of the question, approached it as a theoretical exercise relevant to long-standing philosophical issues, such as nativism, the possibility of common sensibles, and the empiricism-rationalism debate. However, philosophers were quick to adopt the experimentalist's stance as soon as they became aware of recoveries from congenital blindness through ophtalmic surgery. Such recoveries were widely reported to support empiricist positions, suggesting that (...) the question had found its empirical answer. Contrary to this common view, we argue that studies of patients recovering from early blindness through surgery cannot provide an answer. In fact, because of the very nature of such ophtalmological interventions it is impossible to test the question in the empirical conditions outlined by Molyneux. Thus we propose that Molyneux's question be treated as an early thought experiment of a specific kind. Although thought experiments of this kind cannot be turned into actual experimental conditions, they provide a conceptual restructuring of theories. Such restructuring in turn leads to new predictions that can then be tested by normal experiments. In accord with this interpretation, we show that Molyneux's question can be analyzed into a hierarchy of specific questions about vision in its phenomenal and sensory-motor components. Some of these questions do lead to actual experimental conditions that could be studied empirically. (shrink)
There is an exponential speed-up in the number of lines of the quantified propositional sequent calculus over Substitution Frege Systems, if one considers proofs as trees. Whether this is true also for the number of symbols, is still an open problem.
In this paper we introduce canonical extensions of partially ordered sets and monotone maps and a corresponding discrete duality. We then use these to give a uniform treatment of completeness of relational semantics for various substructural logics with implication as the residual(s) of fusion.
We investigate the semantics of the logical systems obtained by introducing the modalities and into the family of substructural implication logics (including relevant, linear and intuitionistic implication). Then, in the spirit of the LDS (Labelled Deductive Systems) methodology, we "import" this semantics into the classical proof system KE. This leads to the formulation of a uniform labelled refutation system for the new logics which is a natural extension of a system for substructural implication developed by the first two authors in (...) a previous paper.

Diotima criticizes, but does not refute, Aristophanes’ thesis that love is desire for completeness. Her argument incorporates that thesis within a more complextheory: eros is desire for the permanent possession of the good, and hence also desire for immortality. Aristophanes cannot account for the aspirations entailed in the desire for fame or in the desire for knowledge. Such aspirations can be understood only with reference to the good. However, the paper shows how time plays a fundamental role in the original (...) pursuit of wholeness at the center of Aristophanes’ myth of the two halves. Diotima appropriates his thesis when she describes the urge to leave behind something similar to what one has been. The desire for immortality is nothing but a desire for completeness pursued by mortal nature against the never-ending destruction of time. (shrink)
We establish a connection between the geometric methods developed in the combinatorial theory of small cancellation and the propositional resolution calculus. We define a precise correspondence between resolution proofs in logic and diagrams in small cancellation theory, and as a consequence, we derive that a resolution proof is a 2-dimensional process. The isoperimetric function defined on diagrams corresponds to the length of resolution proofs.
In 2001 the Italian Government defined Essential Assistance Levels (LEA), which can be considered as an important step forward in the health care system. The Italian health care system would provide payment of essential and uniform aid services in order to safeguard many values such as human dignity, personal health, equal assistance and good health practices. The Ministry of Health has worked to rationalize the National Formulary and to define evaluation methods for drugs in order to choose what to reimburse (...) without penalizing the rights of the individual and society.

The main theme of this article is the phenomenality. Jan Patočka’s asubjective phenomenology distinguishes itself by the description of the plan of phenomenality, where beings can appear and that is independent from everything which appears in it. Only by an universalization of the phenomenological epoché, it is possible to turn our eyes towards the phenomenality itself and to understand its independence. To put the theme of the world and the consciousness between brackets means to discover the structure of the phenomenality, (...) which is constituted by what appears, to which something appears and the way of appearance. The world is the transcendental field of appearance. Everything appears in the world. It is the whole, always given and opened to the human being. The subjectivity is a moment of phenomenality that presupposes the relation with the world. It has a role that makes it an “existence”. It is that to which something appears. Finally the way of appearance: the characters of the phenomenality are “objective mediators”. Mediators because they show the strings that build up the field of appearance, objective because wordly. What they show, even if in the darkness of the absence, is the relation with the world. (shrink)
Originally published as one of the Four Dissertations and then included in the 1758 edition of the Essays, the 1757 paper “Of the Standard of Taste” qualifies as David Hume’s official contribution to criticism.1 A few exceptions aside, no real or thorough effort has been taken by its critics to place the essay in the overall context of Hume’s science of human nature.2 Hume has certainly his share of responsibility in this: “Most of these essays were wrote with a View (...) of being published as WEEKLY-PAPERS, and were intended to comprehend the Design both of the SPECTATORS & CRAFTSMEN. But having dropped that Undertaking, partly from LAZINESS, partly from WANT OF LEISURE, and being willing to make Trial of my .. (shrink)
The present book brings into focus the contrast between explicit and implicit algorithmic descriptions of objects. These themes are considered in a variety of settings, sometimes crossing traditional boundaries. Special emphasis is given to moderate complexity - exponential or polynomial - but objects with multi-exponential complexity also fit in. Among the items under consideration are graphs, formal proofs, languages, automata, groups, circuits, some connections with geometry of metric spaces, and complexity classes (P, NP, co-NP).
We studied patients with left visual extinction following right hemisphere damage in a simple manual reaction time task using brief visual stimuli. With unilateral lateralized stimuli the patients showed a high proportion of unwanted, reflex-like saccades to either side of stimulation. In contrast, with bilateral stimuli there was an overall decrease in the proportion of unwanted saccades, and the vast majority of them were directed toward the ipsilesional side. The implications of these results for the Findlay & Walker model are (...) discussed. (shrink)
The Phaedrus’s Palinode ascribes to the wing the double function of lifting the soul towards truth while itself being nourished by truth. The paper concentrates on the role Socrates ascribes to the wing in the structure and ‘physiology’ of the soul—mortal and divine—as well as on the role it plays in Socrates’ subsequent phenomenological description of falling in love. The experience of love described in Socrates’ first speech—an experience dominated by envy—is examined in light of Socrates’ Palinode, by reference to (...) Socrates’ account of the different ways souls can relate to truth before incarnation. (shrink)
