Tous les empires dans l’histoire ont pu faire ce constat : la puissance n’est pas seulement une question d’armement, mais aussi de contrôle des céréales. Elles ont constitué, jusqu’à l’essor de la consommation de viande, le carburant du travail humain. Cet article permet une charnière bienvenue entre histoire et actualité (« pénurie » et déstabilisation des marchés mondiaux des céréales avec la guerre d’Ukraine). Il retrace l’histoire longue des marchés des céréales dans le monde, les successions des politiques visant leur (...) contrôle (stockage, contrôle des prix, blocage des approvisionnements) ou donnant libre cours à la spéculation, les effets de ces cycles sur les famines et les guerres. Ce qui spécifie le « nouveau capitalisme agraire » contemporain depuis les années 1980, c’est la spéculation totalement dérégulée sur les céréales : marchés virtuels, futures, accaparement des terres, contrôle du vivant et monopoles des semences, entrée de nouveaux acteurs comme banques, fonds de pension, hedge funds. L’auteur propose en conclusion quelques options politiques pour lutter contre cette hégémonie. (shrink)

Driving behaviours and fitness to drive have been assessed using different tools over time: standardized neuropsychological, on-road and driving simulation testing. Nowadays, the great variability of topics related to driving simulation has elicited a high number of reviews. The present work aims to perform a scientometric analysis on driving simulation reviews and to propose a selective review of reviews focusing on critical issues related to validity and fidelity. A scientometric analysis of driving simulation reviews published from 1988 to 2019 was (...) conducted. Bibliographic data from 298 reviews were extracted from Scopus and WoS. Performance analysis was conducted to investigate most prolific Countries, Journals, Institutes and Authors. A cluster analysis on authors’ keywords was performed to identify relevant associations between different research topics. Based on reviews extracted from cluster analysis, a selective review of reviews was conducted to answer questions regarding validity, fidelity and critical issues. USA and Germany are the first two Countries for number of driving simulation reviews. USA is the leading Country with 5 Institutes in the top-ten. Top Authors wrote from 3 to 7 reviews each and belong to Institutes located in North America and Europe. Cluster analysis identified three clusters and eight keywords. The selective review of reviews showed a substantial agreement for supporting validity of driving simulation with respect to neuropsychological and on-road testing, while for fidelity with respect to real-world driving experience a blurred representation emerged. The most relevant critical issues were the a) lack of a common set of standards, b) phenomenon of simulation sickness, c) need for psychometric properties, lack of studies investigating d) predictive validity with respect to collision rates and e) ecological validity. Driving simulation represent a cross-cutting topic in scientific literature on driving, and there are several evidences for considering it as a valid alternative to neuropsychological and on-road testing. Further research efforts could be aimed at establishing a consensus statement for protocols assessing fitness to drive, in order to a) use standardized systems, b) compare systematically driving simulators with regard to their validity and fidelity, and c) employ shared criteria for conducting studies in a given sub-topic.

Il saggio prende in esame due punti della teorizzazione di Harry Frankfurt in merito alla moral agency. Il primo è la corretta concettualizzazione del momento della ‘decisione’ all’interno del­­la ca­tena deliberativa. Vengono esaminati tre passaggi critici: a) la base normativa a cui la decisione ri­spon­de; b) la teoria della ‘unificazione della persona’ attraverso la decisione e c) la distinzione fra ‘scelta’ e ‘decisione’. Il secondo punto è l’ambiguità in­sita nel concetto di ‘doveri d’amore’ pro­posto da Frankfurt. A questo pro­posito vengono (...) esaminate: a) la di­stin­zione fra amore ‘attivo’ e ‘passivo’ e b) la mancata tematizzazione della ‘legittimità del­l’a­more’, ovvero del rap­porto fra l’a­more in quanto relazione sociale e i quadri interpretativi del­la cul­tura entro cui si sviluppa.In this paper two aspects of Harry Frankfurt’s theory of moral agency will be examined. First, his conceptualization of the moment of ‘decision’ wi­thin the deliberative chain will be addressed. Three critical junctures will be dis­cussed: a) the normative basis of the actor’s ‘decision’; b) Frankfurt’s view of the ‘unification’ of the person via decision and c) his distinction of ‘choice’ and ‘decision’. The second point addressed is the ambiguity in­herent in Frankfurt’s notion of ‘duties of love’. With regard to this notion, the following points will be discussed: a) the distinction between ‘active’ and ‘passive’ love and b) Frankfurt’s neglect of the dimension of the ‘le­gi­timacy of love’, i.e. of the nexus of love qua social relation and the inter­pre­tive cadres of the culture within which it unfolds.

Ce livre aborde une question qu'on ne trouve pas telle quelle, explicitement thématisée, chez Merleau-Ponty lui-même, mais qui travaille en profondeur toute sa pensée, à savoir l'expérience de la création. Il s'efforce de respecter la manière dont elle se profile dans les textes du philosophe, le style indirect selon lequel elle émerge chez lui. L'exploration s'en déploie entre quatre grandes régions : " nature ", " histoire ", " langage ", " art ". Chacun de ces domaines, qui interfère sans (...) cesse dans la pensée merleau-pontienne avec les autres, permet de faire ressortir les opérateurs de création qui s'entre-éclairent souvent et demeurent néanmoins irréductibles les uns aux autres. Qu'il s'agisse de spontanéité aveugle ou de " reprise " d'une situation contingente, de différentiel langagier ou de geste pictural relançant l'autophanie du visible même, chaque fois c'est à un autre schème singulier que l'on a affaire. Le phénoménologue vise toujours à élucider la même expérience, c'est-à-dire la manière dont se formule l'ouverture d'un monde. Il essaie de comprendre ce qui se passe entre ou avant les formes - l'effraction de l'événement, l'improbable nuance, le fugitif de l'idée, l'essence qui se met à rayonner. Ainsi apparaît la contribution de la " philosophie d'aujourd'hui " à des enjeux majeurs de l'esthétique. (shrink)

Résumé La critique éthique considère que la valeur éthique d’une œuvre d’art affecte sa valeur artistique.

This book, first published in 1975, provides critical and comprehensive introduction to the philosophy of Leibniz.

Philosophers have rightly condemned lookism—that is, discrimination in favor of attractive people or against unattractive people—in education, the justice system, the workplace and elsewhere. Surprisingly, however, the almost universal preference for attractive romantic and sexual partners has rarely received serious ethical scrutiny. On its face, it’s unclear whether this is a form of discrimination we should reject or tolerate. I consider arguments for both views. On the one hand, a strong case can be made that preferring attractive partners is bad. (...) The idea is that choosing partners based on looks seems essentially similar to other objectionable forms of discrimination. (In particular, the preference for attractive partners is arguably both unfair and harmful to a significant degree.) One can try to resist this conclusion in several ways. I consider three possible replies. The first has to do with the possibility of controlling our partner preferences. The second pertains to attractiveness and “good genes”. The last attempts to link certain aspects of attractiveness to a prospective partner’s personality and values. I argue that the first two replies fail conclusively, while the third only amounts to a limited defense of a particular kind of attractiveness preference. So the idea that we should often avoid preferring attractive partners is compelling. (shrink)

This paper reports the framework, method and main findings of an analysis of cultural milieus in 4 European countries. The analysis is based on a questionnaire applied to a sample built through a two-step procedure of post-hoc random selection from a broader dataset based on an online survey. Responses to the questionnaire were subjected to multidimensional analysis-a combination of Multiple Correspondence Analysis and Cluster Analysis. We identified 5 symbolic universes, that correspond to basic, embodied, affect-laden, generalized worldviews. People in this (...) study see the world as either a) an ordered universe;b) a matter of interpersonal bond;c) a caring society;d) consisting of a niche of belongingness;e) a hostile place. These symbolic universes were also interpreted as semiotic capital: they reflect the capacity of a place to foster social and civic development. Moreover, the distribution of the symbolic universes, and therefore social and civic engagement, is demonstrated to be variable across the 4 countries in the analysis. Finally, we develop a retrospective reconstruction of the distribution of symbolic universes as well as the interplay between their current state and past, present and future socio-institutional scenarios.

According to a widespread view in metaphysics and philosophy of science, all explanations involve relations of ontic dependence between the items appearing in the explanandum and the items appearing in the explanans. I argue that a family of mathematical cases, which I call “viewing-as explanations”, are incompatible with the Dependence Thesis. These cases, I claim, feature genuine explanations that aren’t supported by ontic dependence relations. Hence the thesis isn’t true in general. The first part of the paper defends this claim (...) and discusses its significance. The second part of the paper considers whether viewing-as explanations occur in the empirical sciences, focusing on the case of so-called fictional models. It’s sometimes suggested that fictional models can be explanatory even though they fail to represent actual worldly dependence relations. Whether or not such models explain, I suggest, depends on whether we think scientific explanations necessarily give information relevant to intervention and control. Finally, I argue that counterfactual approaches to explanation also have trouble accommodating viewing-as cases. (shrink)

We discuss potential biorisks from large language models (LLMs). AI assistants based on LLMs such as ChatGPT have been shown to significantly reduce barriers to entry for actors wishing to synthesize dangerous, potentially novel pathogens and chemical weapons. The harms from deploying such bioagents could be further magnified by AI-assisted misinformation. We endorse several policy responses to these dangers, including prerelease evaluations of biomedical AIs by subject-matter experts, enhanced surveillance and lab screening procedures, restrictions on AI training data, and access (...) controls on biomedical AI. We conclude with a suggestion about future research directions in bioethics. (shrink)

The problem of truth in fiction concerns how to tell whether a given proposition is true in a given fiction. Thus far, the nearly universal consensus has been that some propositions are ‘implicitly true’ in some fictions: such propositions are not expressed by any explicit statements in the relevant work, but are nevertheless held to be true in those works on the basis of some other set of criteria. I call this family of views ‘implicitism’. I argue that implicitism faces (...) serious problems, whereas the opposite view is much more plausible than has previously been thought. After mounting a limited defence of explicitism, I explore a difficult problem for the view and discuss some possible responses. (shrink)

Much recent work on mathematical explanation has presupposed that the phenomenon involves explanatory proofs in an essential way. I argue that this view, ‘proof chauvinism’, is false. I then look in some detail at the explanation of the solvability of polynomial equations provided by Galois theory, which has often been thought to revolve around an explanatory proof. The article concludes with some general worries about the effects of chauvinism on the theory of mathematical explanation. 1Introduction 2Why I Am Not a (...)

Philosophers of science since Nagel have been interested in the links between intertheoretic reduction and explanation, understanding and other forms of epistemic progress. Although intertheoretic reduction is widely agreed to occur in pure mathematics as well as empirical science, the relationship between reduction and explanation in the mathematical setting has rarely been investigated in a similarly serious way. This paper examines an important particular case: the reduction of arithmetic to set theory. I claim that the reduction is unexplanatory. In defense (...) of this claim, I offer evidence from mathematical practice, and I respond to contrary suggestions due to Steinhart, Maddy, Kitcher and Quine. I then show how, even if set-theoretic reductions are generally not explanatory, set theory can nevertheless serve as a legitimate foundation for mathematics. Finally, some implications of my thesis for philosophy of mathematics and philosophy of science are discussed. In particular, I suggest that some reductions in mathematics are probably explanatory, and I propose that differing standards of theory acceptance might account for the apparent lack of unexplanatory reductions in the empirical sciences.

Mathematicians distinguish between proofs that explain their results and those that merely prove. This paper explores the nature of explanatory proofs, their role in mathematical practice, and some of the reasons why philosophers should care about them. Among the questions addressed are the following: what kinds of proofs are generally explanatory (or not)? What makes a proof explanatory? Do all mathematical explanations involve proof in an essential way? Are there really such things as explanatory proofs, and if so, how do (...) they relate to the sorts of explanation encountered in philosophy of science and metaphysics? (shrink)

This article argues that William James's thinking in The Varieties and elsewhere contains the view that social institutions, such as religious congregations and schools, are mediators between the private and public spheres of life, and are necessary for transforming personal feelings, ideals and beliefs into moral action. The Exercises of St Ignatius and the Just Community moral education approach serve as examples. Criticisms of the more commonly held view that James recognised only individual personal experiences as valid religious expressions are (...) marshalled. Furthermore, we argue that moral action or saintliness, the ultimate expression of religious faith according to James, is fundamentally social. The commonalities that the phenomenologies of moral action of St Ignatius and Lawrence Kohlberg have with William James's view are used to support the argument. (shrink)

The field of AI safety aims to prevent increasingly capable artificially intelligent systems from causing humans harm. Research on moral alignment is widely thought to offer a promising safety strategy: if we can equip AI systems with appropriate ethical rules, according to this line of thought, they'll be unlikely to disempower, destroy or otherwise seriously harm us. Deontological morality looks like a particularly attractive candidate for an alignment target, given its popularity, relative technical tractability and commitment to harm-avoidance principles. I (...) argue that the connection between moral alignment and safe behavior is more tenuous than many have hoped. In general, AI systems can possess either of these properties in the absence of the other, and we should favor safety when the two conflict. In particular, advanced AI systems governed by standard versions of deontology need not be especially safe. (shrink)

Gauss’s quadratic reciprocity theorem is among the most important results in the history of number theory. It’s also among the most mysterious: since its discovery in the late 18th century, mathematicians have regarded reciprocity as a deeply surprising fact in need of explanation. Intriguingly, though, there’s little agreement on how the theorem is best explained. Two quite different kinds of proof are most often praised as explanatory: an elementary argument that gives the theorem an intuitive geometric interpretation, due to Gauss (...) and Eisenstein, and a sophisticated proof using algebraic number theory, due to Hilbert. Philosophers have yet to look carefully at such explanatory disagreements in mathematics. I do so here. According to the view I defend, there are two important explanatory virtues—depth and transparency—which different proofs (and other potential explanations) possess to different degrees. Although not mutually exclusive in principle, the packages of features associated with the two stand in some tension with one another, so that very deep explanations are rarely transparent, and vice versa. After developing the theory of depth and transparency and applying it to the case of quadratic reciprocity, I draw some morals about the nature of mathematical explanation. (shrink)

In a recent letter, Dillion et. al (2023) make various suggestions regarding the idea of artificially intelligent systems, such as large language models, replacing human subjects in empirical moral psychology. We argue that human subjects are in various ways indispensable.

Recent progress in artificial intelligence (AI) has drawn attention to the technology’s transformative potential, including what some see as its prospects for causing large-scale harm. We review two influential arguments purporting to show how AI could pose catastrophic risks. The first argument — the Problem of Power-Seeking — claims that, under certain assumptions, advanced AI systems are likely to engage in dangerous power-seeking behavior in pursuit of their goals. We review reasons for thinking that AI systems might seek power, that (...) they might obtain it, that this could lead to catastrophe, and that we might build and deploy such systems anyway. The second argument claims that the development of human-level AI will unlock rapid further progress, culminating in AI systems far more capable than any human — this is the Singularity Hypothesis. Power-seeking behavior on the part of such systems might be particularly dangerous. We discuss a variety of objections to both arguments and conclude by assessing the state of the debate. (shrink)

Although Broad published many books in his lifetime, this volume is unique in presenting some of his most interesting unpublished writings. Divided into five clear sections, the following figures and topics are covered: Autobiography, Hegel and the nature of philosophy, Francis Bacon, Hume's philosophy of the self and belief, F. H. Bradley, The historical development of scientific thought from Pythagoras to Newton, Causation, Change and continuity, Quantitative methods, Poltergeists, Paranormal phenomena. -/- Each section is introduced and placed in context by (...) the editor, Joel Walmsley. The volume also includes an engaging and informative foreword by Simon Blackburn. It will be of great value to those studying and researching the history of twentieth-century philosophy, metaphysics, and the recent history and philosophy of science, as well as anyone interested in Broad's philosophical thought and his place in the history of philosophy.

A proof P of a theorem T is transferable when a typical expert can become convinced of T solely on the basis of their prior knowledge and the information contained in P. Easwaran has argued that transferability is a constraint on acceptable proof. Meanwhile, a proof P is fixable when it’s possible for other experts to correct any mistakes P contains without having to develop significant new mathematics. Habgood-Coote and Tanswell have observed that some acceptable proofs are both fixable and (...) in need of fixing, in the sense that they contain nontrivial mistakes. The claim that acceptable proofs must be transferable seems quite plausible. The claim that some acceptable proofs need fixing seems plausible too. Unfortunately, these attractive suggestions stand in tension with one another. I argue that the transferability requirement is the problem. Acceptable proofs need only satisfy a weaker requirement I call “corrigibility”. I explain why, despite appearances, the corrigibility standard is preferable to stricter alternatives. (shrink)

Models are indispensable tools of scientific inquiry, and one of their main uses is to improve our understanding of the phenomena they represent. How do models accomplish this? And what does this tell us about the nature of understanding? While much recent work has aimed at answering these questions, philosophers' focus has been squarely on models in empirical science. I aim to show that pure mathematics also deserves a seat at the table. I begin by presenting two cases: Cramér’s random (...) model of the prime numbers and the function field model of the integers. These cases show that mathematicians, like empirical scientists, rely on unrealistic models to gain understanding of complex phenomena. They also have important implications for some much-discussed theses about scientific understanding. First, modeling practices in mathematics confirm that one can gain understanding without obtaining an explanation. Second, these cases undermine the popular thesis that unrealistic models confer understanding by imparting counterfactual knowledge. (shrink)

Lawrence Kohlberg's Approach to Moral Education presents what the late Lawrence Kohlberg regarded as the definitive statement of his educational theory. Addressing the sociology and social psychology of schooling, the authors propose that school culture become the center of moral education and research. They discuss how schools can develop as just and cohesive communities by involving students in democracy, and they focus on the moral decisions teachers and students face as they democratically resolve problems. As the authors put it: "...we (...) propose an educational renewal of our democratic society.... We have attempted to establish schools that do more than just teach about democratic citizenship, that are themselves democratic societies.". (shrink)
