The construction of memory in colonial Eritrea: Eritreans, Mestizos and Italians. Focusing on some passages of life histories collected in Asmara and based on the ‘memory of Italy’, I study the representation of the past in order to reveal the shaping of the subjective experience by the colonial discourse in Eritrea. If the main aim of my essay is the understanding of the play of interactions between individuals and collectivity, one more important element I take into account is ‘memory’ seen (...) as a “social selection of remembering” (Halbwachs). I try to connect the social position and narrative role of single members (of the Eritrean society) to the meaning it takes the ‘going back to the past’ for them as individuals belonging to a group (an Eritrean, a Mestizo, an Italian) in relation to the past and the present. The consequence is that the logic dominant/dominated is inadequate to explain the internal articulations of the colonial context and that the focus must be shifted on individual and collective systems of expectations and on the negotiations of meaning resulting from a “past always to be recovered” and a “present always to be rebuilt”.

Recent years have been blessed with an abundance of logical systems, arising from a multitude of applications. A logic can be characterised in many different ways. Traditionally, a logic is presented via the following three components: 1. an intuitive non-formal motivation, perhaps tie it in to some application area 2. a semantical interpretation 3. a proof theoretical formulation. There are several types of proof theoretical methodologies, Hilbert style, Gentzen style, goal directed style, labelled deductive system style, and so on. The (...) tableau methodology, invented in the 1950s by Beth and Hintikka and later per fected by Smullyan and Fitting, is today one of the most popular, since it appears to bring together the proof-theoretical and the semantical approaches to the pre of a logical system and is also very intuitive. In many universities it is sentation the style first taught to students. Recently interest in tableaux has become more widespread and a community crystallised around the subject. An annual tableaux conference is being held and proceedings are published. The present volume is a Handbook a/Tableaux pre senting to the community a wide coverage of tableaux systems for a variety of logics. It is written by active members of the community and brings the reader up to frontline research. It will be of interest to any formal logician from any area. (shrink)

In our information societies, tasks and decisions are increasingly outsourced to automated systems, machines, and artificial agents that mediate human relationships, by taking decisions and acting on the basis of algorithms. This raises a critical issue: how are algorithmic procedures and applications to be appraised and governed? This question needs to be investigated, if one wishes to avoid the traps of ICTs ending up in isolating humans behind their screens and digital delegates, or harnessing them in a passive role, by (...) curtailing their freedom and autonomy.

In this paper we provide a detailed proof-theoretical analysis of a natural deduction system for classical propositional logic that (i) represents classical proofs in a more natural way than standard Gentzen-style natural deduction, (ii) admits of a simple normalization procedure such that normal proofs enjoy the Weak Subformula Property, (iii) provides the means to prove a Non-contamination Property of normal proofs that is not satisfied by normal proofs in the Gentzen tradition and is useful for applications, especially in formal argumentation, (...) (iv) naturally leads to defining a notion of depth of a proof, to the effect that, for every fixed natural k, normal k-depth deducibility is a tractable problem and converges to classical deducibility as k tends to infinity.

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.

INTRODUCTION The editors of this volume - Jarvie and D'Agostino - encountered John Watkins at such different times in his career that they have never ...

Free Public Reason examines the idea of public justification, stressing its importance but also questioning the coherence of the concept itself. Although public justification is employed in the work of theorists such as John Rawls, Jeremy Waldron, Thomas Nagel, and others, it has received little attention on its own as a philosophical concept. In this book Fred D'Agostino shows that the concept is composed of various values, interests, and notions of the good, and that no ranking of these is possible. (...) The notion of public justification itself is thus shown to be contestable. In demonstrating this, D'Agostino undermines many current political theories that rely on this concept. Having broken down the foundations of public justification, D'Agostino then offers an alternative model of how a workable consensus on its meaning might be reached through the interactions of a community of interpreters or delegates at a constitutional convention.

Ian C. Jarvie developed the idea of situational logic in a subtle and effective way. He was also interested in, as well as a contributor to, the institution of academic publication. This chapter provides a situational analysis of an important recurrent pattern in academic publishing, namely, the concentration of work around particular topics, despite the fact that most such work will be unrewarded in the economy of esteem that is meant to be in play.

Normal science involves persistent collective application of an agreed research agenda. Anomaly can threaten normal science, but so too can “undue persistence” in that agenda by a normal science peer group. We consider how “undue persistence” might be a collective effect of the common incentive structure that individual members of the peer group typically face in relation to their careers. To understand how “undue persistence” might be ameliorated, we consider the affordances of a peer’s membership of a departmental collegium, organized (...) on a different basis than the specialist peer group and hence able to supply the individual scholar with kinds of information and critical comment that may occasion off-agenda contributions to the specialty. The idea of brokerage is borrowed from the sociology of innovation to see how a scholar’s departmental colleagues might be able to broker new ways of thinking that can assist in the avoidance of “undue persistence”.

Philosophy of Social Science, that social scientific investigations do not and cannot meet the liberal requirement of "neutrality" most familiar to social scientists in the form of Max Weber's requirement of value-freedom. He argues, moreover, that this is for "institutional," not idiosyncratic, reasons: methodological demands (e.g., of validity) impel social scientists to pass along into their "objective" investigations the values of the people, groups, and cultures they are studying. In this paper, I consider the implications of Root's claims for the (...) use of social scientific results in the formation of policy in a democratic society. In particular, I argue that Root's results amplify familiar "post-modernist" conclusions: there is no "neutral" and "objective" basis for policy-making. (shrink)

Is expertise in applied ethics compatible with individual autonomy and democratic self‐governance? This depends on whether a ‘tracking condition’ is satisfied for expert claims about issues in applied ethics. This condition requires that, when expert deliberations are properly conducted they ‘track’ the courses of reasoning that the experts’ clients would themselves have undertaken if they had (perhaps subject to certain conditions) considered the matters for themselves. Pluralism of the kind thematised by Isaiah Berlin and Stuart Hampshire suggests that the tracking (...) condition typically will not be satisfied and, hence, that whatever experts are praticising in applied ethics they are doing it contrary to democratic principles of autonomy and self‐government. The implications of this result are sketched and some standard objections briefly considered. (shrink)

Decision-making assisted by algorithms developed by machine learning is increasingly determining our lives. Unfortunately, full opacity about the process is the norm. Would transparency contribute to restoring accountability for such systems as is often maintained? Several objections to full transparency are examined: the loss of privacy when datasets become public, the perverse effects of disclosure of the very algorithms themselves, the potential loss of companies’ competitive edge, and the limited gains in answerability to be expected since sophisticated algorithms usually are (...) inherently opaque. It is concluded that, at least presently, full transparency for oversight bodies alone is the only feasible option; extending it to the public at large is normally not advisable. Moreover, it is argued that algorithmic decisions preferably should become more understandable; to that effect, the models of machine learning to be employed should either be interpreted ex post or be interpretable by design ex ante.

What is the relation between autonomy, education, and democracy?

In this article, I focus on Johann Nikolaus Tetens’s linguistic theory to make three arguments: (a) this linguistic theory endorses a phonological (contra phonetic) approach to the acoustic sphere of language; (b) the phonological approach is based on the idea that sounds can turn into phonemes (of a properly human language) only when a minimally rational reflection on them is made; and (c) the phonological approach allows us to understand the phoneme as a differential unity, as being composed of structure (...) and function, and as giving a theoretical basis for language learning.

We have considered two strategies for using native utterances as evidence for assigning native beliefs. We have shown that each of these two strategies (literalism and symbolism) can avoid the logical difficulties mentioned in section 1 — so long, at least, as we employ an account of the logical form of belief sentences developed by Burdick. We have also considered the methodological principles which provide the basis for translational practice. Based on our consideration of these principles, we then argued that (...) we must prefer the literalist strategy for attributing beliefs. Only the literalist strategy enables us to provide a recursive account of the significance of native utterances, and only the literalist strategy enables us to maximize the truth of our claims about native beliefs.

Deductive inference is usually regarded as being “tautological” or “analytical”: the information conveyed by the conclusion is contained in the information conveyed by the premises. This idea, however, clashes with the undecidability of first-order logic and with the (likely) intractability of Boolean logic. In this article, we address the problem both from the semantic and the proof-theoretical point of view. We propose a hierarchy of propositional logics that are all tractable (i.e. decidable in polynomial time), although by means of growing (...) computational resources, and converge towards classical propositional logic. The underlying claim is that this hierarchy can be used to represent increasing levels of “depth” or “informativeness” of Boolean reasoning. Special attention is paid to the most basic logic in this hierarchy, the pure “intelim logic”, which satisfies all the requirements of a natural deduction system (allowing both introduction and elimination rules for each logical operator) while admitting of a feasible (quadratic) decision procedure. We argue that this logic is “analytic” in a particularly strict sense, in that it rules out any use of “virtual information”, which is chiefly responsible for the combinatorial explosion of standard classical systems. As a result, analyticity and tractability are reconciled and growing degrees of computational complexity are associated with the depth at which the use of virtual information is allowed. (shrink)

Through the seasons, you are attentive to God's inherent timing and intended purpose at every stage and episode in life. Obstacles give way to opportunities and hindrances to heights, as you surrender to a life of completion with a realization that it is the journey that matters at the finish.

La reflexión de Francesco D'Agostino procede a partir de una sintética presentación de la genealogía y de los sucesivos desarrollos del concepto de "persona" en la cultura occidental, deteniéndose específicamente sobre su reciente identificación positivistá con la categoría de "sujeto de derecho" - y sobre su consiguiente manipulabilidad pragmática y normativa. Tal paradigma ha entrado en crisis, como testimonian las irresolubles problemáticas surgidas en torno a la disciplina legal del bias, y en particular a la dificultad, que se deriva directamente, (...) de contener normativamente toda tentación de un superpoder biopolítico: ni el intento empirista de rehabilitar el concepto de base de la capacidad de autodeterminación, aparece verdaderamente serio y persuasivo. Más prometedora resulta en cambio la propuesta de regresar a una fundamentación del derecho en la persona y en su concreta corporeidad: yendo más allá de las propuestas de Stefano Rodota, puestas fecundamente en confrontación con el personalismo de Elio Sgreccia, D'Agostino sugiere tomar en serio la idea de "biografía" para redescubrir en el fondo un integrado, por ser relacional, concepto de persona humana. En este empeño teorético aparece rico de consecuencias el paso de la consideración prioritaria de los cuerpos a aquella de la "carne", mucho más densa desde el punto de vista filosófico y teológico: tanto por vía de su referencia intrínseca a la vulnerabilidad, como por su estructural apertura, alternativa a la cerrazón individualista del cuerpo en sí mismo, a la relación con el otro por sí mismo y sobre todo con el Dios encarnado.

This book was published in 2003.This volume presents a detailed examination of incommensurability in the value-theoretical sense. Exploring how choosers deal with problems and constraints of choice, the author draws on work in cognitive psychology, in sociology, in jurisprudence, in economics, and in the theory of value to show how choosers learn to make trade-offs when there is potential incommensurability among the options they are considering. The analysis is also informed by recent work in the tradition of Michel Foucault. With (...) so many modern devices and ideals of government dependent on the comparability of options, this book is timely and can inform public debate about de-regulation, user-pays, accountability, and the substitution of market mechanisms for government regulation and supply.

To understand the continuing importance of John Rawls’s work, we need to understand the background, the object and the method of his fifty-year quest as a political thinker. The background to Rawls’s investigation was a (carefully circumscribed) acknowledgement of a certain kind of evaluative pluralism. The object of Rawls’s work was to develop a method of commensuration that would enable us, the free and equal citizens of a democratic society, to identify a common basis for our dealings, in search of (...) mutual benefit, with one another. Finally, the method used by Rawls in his work was broadly, though tacitly rather than explicitly, pragmatist in character, especially in the sense that Rawls was aiming, now explicitly, to develop principles of political association that generate their own support in the attitudes and actions of those whose behavior they are intended to guide.

Critical notice of The Order of Public Reason by Gerald Gaus.

In identifying that the 'essential tension' is the balance between conservative and innovative approaches in the development of knowledge - tried-and tested or new directions - Kuhn pointed out that these two attitudes are both appropriate. This study adds to this picture the social and psychological dynamics that underpin any such balancing.
