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)

FDE is a logic that captures relevant entailment between implication-free formulae and admits of an intuitive informational interpretation as a 4-valued logic in which “a computer should think”. However, the logic is co-NP complete, and so an idealized model of how an agent can think. We address this issue by shifting to signed formulae where the signs express imprecise values associated with two distinct bipartitions of the set of standard 4 values. Thus, we present a proof system which consists of (...) linear operational rules and only two branching structural rules, the latter expressing a generalized rule of bivalence. This system naturally leads to defining an infinite hierarchy of tractable depth-bounded approximations to FDE. Namely, approximations in which the number of nested applications of the two branching rules is bounded. (shrink)

Il tema della complessità della scienza è stato da qualche decennio oggetto di una vasta letteratura sia sul versante più strettamente scientifico, sia sul piano filosofico. Un argomento emerso con notevole interesse ha riguardato un aspetto della complessità inteso come rinuncia a una generalizzazione dei procedimenti assiomatico-deduttivi come metodo generale della ricerca scientifica. È stata espressa la convinzione che la fisica pre-relativistica sia stata fondata prevalentemente sul trionfo di questo metodo, sulla scia, fra l’altro, della gloriosa tradizione dei Principia newtoniani. (...) Pur riconoscendo la sua imponenza storica e concettuale, che ha condotto spesso a una sua identificazione con la stessa tradizione della scienza occidentale, la mia ricerca storica ha evidenziato una posizione antagonista presente nelle idee di Newton, e ripresa da due grandi fisici ottocenteschi, Ampere e Maxwell, posizione consistente in un ricorso alla cosiddetta deduzione dai fenomeni, un metodo di ricerca che rappresenta un’importante alternativa rispetto al metodo assiomatico-deduttivo. Nei primi decenni del nuovo secolo, si impongono poi progressivamente le idee di Einstein, che sul problema del metodo presentano un’irrisolta problematica. La celebrazione del metodo assiomatico-deduttivo si contrappone ad una lode dell’osservazione dei fenomeni e della riflessione sugli esperimenti, una variazione sul tema della deduzione dai fenomeni. Seppure i contributi del grande scienziato alle teorie derivate dagli assiomi del campo generalizzato non portarono a teorie conclusive, le sue idee in merito contribuirono enormemente alla moderna riflessione storico-epistemologica sulla scienza.

Contemporary psychologism has been amended for most of the objections by its opponents over a century ago. However, some authors still raise doubts about its ability to account for some peculiar properties of logic. In particular, it is argued that the psychological universality of patterns of inferential behavior is not sufficient to account for the normativity of logic. In this paper, I deal with the issue and offer three alternative solutions that do not rely on mere empirical universality. I will (...) use the works of Laurence Jonathan Cohen, Diego Marconi and Marcello D'Agostino, adapting them for the purpose of defending logical psychologism. I will therefore argue that, although more refined work on the subject is needed, contemporary psychologism has the key resources to retain its place in the philosophical debate on the foundations of logic.

The thesis that gives the discourse its characteristic liberal twist is that of the possibility not just of arguing on values in principle but of effective communication about values between different social subjects, instead of, for example, mere compromise between opposing interests that are unable to understand each other's reasons or imposition of one interest on another. From this thesis derives the possibility of the proposal of combining "science" and "ethics".

A critical discussion of DAVID WILSON and WILLIAM DIXON, A History of Homo Economicus. The nature of the moral in economic theory, London and New York, Routledge, pp. xviii+123 ISBN 978-0-415-59568-1. I declare agreement with one basic idea in this book, that economic discourse is performative, or economic theory is not pure theorìa. I add several objections to the historical reconstruction carried out os such authors as Malthus and Ricardo and I object to the definition adopted of homo economicus.

I intend to: a) clarify the origins and de facto meanings of the term relativism; b) reconstruct the reasons for the birth of the thesis named “cultural relativism”; d) reconstruct ethical implications of the above thesis; c) revisit the recent discussion between universalists and particularists in the light of the idea of cultural relativism.. -/- 1.Prescriptive Moral Relativism: “everybody is justified in acting in the way imposed by criteria accepted by the group he belongs to”. Universalism: there are at least (...) some judgments which are valid inter-culturally Absolutism: there are at least some particular prescriptions which are valid without exception everywhere and always -/- 2. The traditional proof of prescriptive moral relativism: the argument from variability: Judgments, rules, and shared values are de facto variable in time and space. The traditional counter-proof: examples of variability do not prove what skeptics contend. -/- 3. Pre-history of the doctrine -Ancient sophists: either immoralist or contractualist -Modern moral scepticism (xvii c.): variability as an historical and ethnographic fact supports a sceptical conclusion more moderate than sheer immoralism. - Voltaire, Kant, Reid counter-attack pointing at a universally shared moral sense - Romantics and idealists stage an even more moderate reformulation: instead of universally shared moral sense they point at the Spirit of a People which is: a)alternative to abstract and universal philosophical systems as far as it is lived ‘culture’; b) indivisible unity with an inner harmony and a source of normative standards; c) dynamic, in so far as it is a manifestation of the Spirit through the becoming of National cultures. -/- 4. The birth of Cultural Relativism and its ethical implications 4.1. The 18th c. doctrine was the noble savage (a non-historical doctrine: state of nature vs. social state) 4.2 Edward Tylor (1832-1817) and ethnocentric historicism Savage moral standards are real enough, but they are far and weaker than ours. 4.3 Boas and Malinowski and an holistic reaction to ethnocentric historicism -/- Franz Boas (1858-1942): a) Development of civilizations is not ruled by technical progress nor does it follow a one-way path; instead there are parallel developments (for ex. Agriculture does not follow stock-raising); b) racial characters have no relevance in development of civilization; c) we are not yet in a position to compare externally identical kinds of behaviour till we have not yet understood beliefs and intentions laying at their roots (for ex.: “From an ethnological point of view murder cannot be considered as a single phenomenon”; d) we should distinguish among different practices which are only superficially similar (fro ex. practices traditionally classified under the label “tabù”); e) there is as a fact just one normative ethic, constant in its contents but varying in its extension; f) the implication is not that we cannot judge behavior by members of other groups; it is only a recommendation of caution. -/- Bronislaw Malinowski (1884-1942): a) against Tylor’s and Frazer’s “magpie” methodology, field-work is required, a culture as a whole should be observed from inside; individual elements are incomprehensible; b) a culture is an organic whole; c) its elements are accounted for by their function (economy), avoiding non-observables (empio-criticism). -/- Ruth Benedict and Melville Herskovitz identify Boas’s approach with “cultural relativism”. Benedict: what is normal and abnormal is to be judged on a culture’s own standards, not on our own (“Anthropology and the Abnormal”). Herskovits: “Boas adumbrates what we have come to call cultural relativism” (The Mind, p. 10); “Judgements are based on experience, and experience is interpreted by each individual in terms of his own enculturation” (Man and his Works). -/- 4. How analytic philosophy understood and misunderstood the discussion 4.1. At the beginning of the 20th c., the new view in ethics was non-cognitivism (emotivist and subjectivist). Eric Westermark combines this view with an old-style ethnographic approach in support of relativity of moralities. Moralities are codes, or systems of emotive ‘disinterested’ reactions selected by evolution on their usefulness in terms of survival value for the society that is the carrier of such systems or codes. The moral relativity thesis: there are cases of disagreement that cannot be settled even after agreement about facts. 4.2 Anti-realists Brandt, Mackie, Gilbert, Harman adopt Westermark’s approach in a more sophisticated version: a) moralities are codes with an overall function and may be appraised only as wholes; b) variability is an argument for moral subjectivism; c) apparent legitimacy of deriving shift from ought is legitimized only within one institution d) morality should not be described but instead made, and existing moralities may be improved. Is it ‘real’ relativism? It is clearly subjectivism (a metaethical thesis). The normative thesis is that there better and worse codes, and survival values is the normative standard. -/- 4.3 Particularists MacIntyre, Sandel, Taylor, Wiggins, McDowell ‘Wittgensteinian’ prospectivist arguments bent to support weak-relativist claims MacIntyre: there is ‘incommensurability’ between different theoretical systems in both science and ethics. No argument is possible through different systems Different traditions may coexist for a long time without being able to bring their conflicts to a rational solution. -/- 4.4 Kantian universalists Baier, Gewirth, Rawls, Apel, Habermas Shared claim: justice concerns the right and is universal in so far as it may be based on minimal assumptions Other virtues are relative to context in so far as they are related to comprehensive views of the good - O’Neill criticism: a) it is an assumption shared by both alignments; b) after an alleged crisis brought about by alleged loss of metaphysical certainties, theories of justice have dropped demanding assumptions and kept universalism, virtue theories have kept demanding assumptions and dropped universalism; c) the opposition of virtue and justice has arisen in an unjustified way. O’Neill’s positive proposal: ‘constructive’ procedures may be adopted both (i) concerning all the range of virtues and (ii) across cultures once we abandon idealization and confine ourselves to abstraction from real-world cases. -/- 4.5 A metaethical relativist and anti-relativist normative ethicists: Bernard Williams Williams: vulgar relativism may be assumed to claim that: a) 'just' means 'just in a given society'; b) 'just in a given society' is to be understood in functionalist sense; c) it is wrong for one society’s members to condemn another society’s values. It is inconsistent since in (c) uses ‘just’ in a non-relative way that has been excluded in (a). William’s positive proposal: i) keep a number of substantive or thick ethical concepts that will be different in space and time; ii) admit that public choices are to be legitimized through recourse to more abstract procedures and relying on more thin ethical concepts. -/- 5. Critical remarks 5.1 The only real relativism available is ‘vulgar’ relativism (Westermark?) 5.2. Descriptive universalism (or absolutism) has a long pedigree, from Cicero on, reaching Boas himself but it is useless as an answer to normative questions 5.3. Twentieth-century philosophical discussion seems to discuss an ad hoc doctrine reconstructed by assembling obsolete philosophical ideas but ignoring the real theory of cultural relativism as formulated by anthropologists. -/- 6. A distinction between ethoi and ethical theories as a way out of confusions a)There are systems of conventions de facto existing. These may be studies from outside as phenomena or facts. b)There is moral argument and this, when studies from outside, is a fact, but this does not influence in any degree the possible validity of claims advanced. c) the difference between the above claims and Mackie’s criticism to Searle’s argument of the promising game is that promises, arguments etc. are also phenomena, but they are also communicative phenomena with a logical and pragmatic structure. -/- 7.Conclusions: a) cultural relativism, as a name for Boas’s methodology is a valuable discovery, and in this sense we are all relativists; b) ethical relativism, as an alleged implication of cultural relativism, has been argued in a philosophically quite unsophisticated way by Benedict and Herskovits; philosophers apparently discussed ethical relativism in the basis of a rather faint impression of what cultural relativism had been. c) a full-fledged ethical relativism has hardly been defended by anybody among philosophers; virtually no modern philosopher really argued a prescriptive version of the thesis; d) we may accept the grain of truth in ethical relativism by including relativist critique to ethical absolutism into a universalist normative doctrine that be careful in separating open-textured formulations of universal claims from culturally conditioned particular prescriptions. -/- .

This paper reconstructs the ways in which metaphors are used in the text of “The Wealth of Nations”. Its claims are: a) metaphor statements are basically similar to those in the “Theory of the Moral Sentiments”; b) the metaphors’ ‘primary subjects’ refer to mechanics, hydraulics, blood circulation, agriculture, medicine; c) metaphors may be lumped together into a couple of families, the family of mechanical analogies, and that of iatro-political analogies. Further claims are: a basic physico-moral analogy is the framework for (...) Smith’s psychological theory as well as for his overall social theory and for his theory of market mechanisms; a iatro-mechanical analogy is as pervasive as the physico-moral analogy and provides the framework for his overall evolutionary theory of society; the invisible-hand simile relies on the physico-moral analogy, and elaborates on the role of vis attractiva and vis a tergo in mechanics.

I discuss the three theses defended by Anscombe in 'Modern Moral Philosophy'. I argue that: a) her answer to the question "why should I be moral?" requires a solution of the problem of theodicy and ignores any attempts to save the moral point of view without recourse to divine retribution; b) her notion of divine law is an odd one, more neo-Augustinian than Biblical or Scholastic; c) her image of Kantian ethics and intuitionism is the impoverished image manufactured by consequentialist (...) opponents for polemical purposes, which she seems to endorse even though it is an image manufactured by the same writers she choose as a polemical target; d) the difficulty to identify the "relevant descriptions" of acts is not an argument in favor of an ethics of virtue and against consequentialism or Kantian ethics, and indeed the role of judgment in the latter is precisely a response to difficulties raised by the case of judgment concerning future action, a case for which Anscombe herself has nothing better to offer.

Amerini declares that by this book he did not want to make any contribution to the contemporary bioethical debate, or in another way, he wanted to give a preliminary contribution of great importance. His opinion on the implications of Aquinas's embryological theory for today's bioethical debate is in fact that it "certainly has some bioethical consequences, but it does not give rise to one particular bioethical theory rather than another. It is, as said, a philosophical explanation, traced in terms of (...) Aristotelian metaphysics, and as such can only be of support for the elaboration of a bioethical theory". (shrink)

The aim of this study is to illustrate the role played by Augustine’s Commentary on the Genesis in the writings of Thomas Aquinas. This work is of great importance for Aquinas, not only because it is the work where Augustine clarifies his interpretation of creation, but also because creation is, among the theological topics, perhaps the most philosophical, insofar as it gives the opportunity of elaborating on many philosophical issues. In particular, the goal of the study is to rethink the (...) positions of Aquinas and Augustine on one of these issues, that is the relationship between soul and body. I mean to call into question two historiographical theses: first, that Augustine and Aquinas formulate positions that are irreconcilable with each other, and second, that they in no way address that which we today call the Mind-Body Problem.

The enormous increasing of connections between people and the noteworthy enlargement of domains and methods in sciences have augmented extraordinarily the cardinality of the set of meaningful human symbols. We know that complexity is always on the way to become complication, i.e. a non-tractable topic. For this reason scholars engage themselves more and more in attempting to tame plurality and chaos. In this book distinguished scientists, philosophers and historians of science reflect on the topic from a multidisciplinary point of view. (...) Is it possible to dominate complexity through reductionism? Are there other conceptual instruments useful to take account of complexity? What is complexity in biology, mathematics, physics and philosophy of mind? These are some of the questions which are faced in this volume. (shrink)

L’Exercitium academicum circa praescientiam daemonum (1666), pubblicato nella riformata Jena, tematizza una questione dibattuta nella Scolastica fra XIII e XIV secolo ma le cui radici risalgono ad Agostino d'Ippona, cui si deve il primo testo sull'argomento: la prescienza dei demoni. L'analisi segue la traccia del De divinatione daemonum agostiniano, mentre appare critica nei confronti delle posizioni di Tommaso d'Aquino e dei tomisti. Ad esse, in particolare riguardo alla natura delle facoltà intellettive demoniche, egli contrappone Giovanni Duns Scoto, Durando di san (...) Porziano e non meglio specificati nominales, accomunati in un indistinto riferimento alla teoria delle species. Ciò non toglie che il testo segua poi Tommaso nell'articolazione delle forme di prescienza dei demoni e nella definizione di questa come conoscenza congetturale. Scopo del nostro intervento sarà infatti mostrare, attraverso l'analisi che per la prima volta sarà condotta sul testo, lo spaccato di una comunità conversazionale nella quale le linee di forza e le distinzioni che animano il dibattito si mostrano autonome rispetto alle posizioni storiche di cattolici e riformati. Nell’Exercitium, Duns Scoto è contrapposto ai tomisti e, con Agostino e Durando di san Porziano – che costituisce una fonte comune del dibattito secentesco insieme a Bonaventura, Aureolo, Suarez, Vazquez, Gregorio di Valencia, e in tale veste sarà ripreso di lì a poco da Leibniz -, è cooptato tra gli autori a sostegno della sua tesi. Lungi dall'essere un esercizio di eclettismo o la stanca ripetizione di formule scolastiche, lo scritto getta luce su un dibattito universitario nel quale le fonti sono usate non come auctoritates ma quale repertorio di teorie da smontare e rimontare; ad esse l’Exercitium attinge per soluzioni che si definiscono in relazione a finalità filosofiche o dottrinali, ma non politiche né confessionali.

L'antigiudaismo cristiano è essenzialmente la credenza che il popolo ebraico debba rinunciare alla propria fede e convertirsi al cristianesimo. In questo testo viene studiata la prima forma sistematica di antigiudaismo sviluppata in termini filosofici e teologici da Agostino d'Ippona. Alla luce dell'analisi filosofica sembra che l'avversione di Agostino per la fede ebraica si fondi su un'autentica rimozione della specificità del popolo eletto, della Legge e della Rivelazione sul Sinai.

La storia di un’idea che ha attraversato i secoli, dal mondo pagano e poi cristiano fino alle soglie dell’età contemporanea, passando per il lungo millennio medievale: l’intelligenza del diavolo, che si manifesta nella preveggenza e in capacità cognitive fuori dal comune. Ma qual è la natura di questo potere? Com’è possibile che Lucifero, principe degli angeli e sommamente sapiente, abbia peccato? E ciò significa che l’intelligenza è intrinsecamente demoniaca? Conoscenza e bontà possono convivere, e si può essere al contempo intelligenti (...) e malvagi, o addirittura malvagi perché intelligenti? Tutti interrogativi che si raccolgono attorno alla figura teologica del diavolo e al suo “scandaloso” potere cognitivo. Una questione che si muove tra filosofia, teologia, letteratura, scienza e mito, tessendo le fila di una storia intellettuale che vede spesso come protagonisti autori e testi poco noti, ma capaci di raccogliere il testimone di auctoritas come Agostino d’Ippona e Anselmo d’Aosta, Dante e Tommaso d’Aquino, Cartesio e Voltaire.

This essay presents the conditional probability of co-contribution account of the individuation of cognitive systems (CPC) and argues that CPC provides an attractive basis for a theory of the cognitive self. The argument proceeds in a largely indirect way, by emphasizing empirical challenges faced by an approach that relies entirely on predictive processing (PP) mechanisms to ground a theory of the cognitive self. Given the challenges faced by PP-based approaches, we should prefer a theory of the cognitive self of the (...) sort CPC offers, one that accommodates variety in the kinds of mechanism that, when integrated, constitute a cognitive system (and thus the cognitive self), to a theory according to which the cognitive self is composed of essentially one kind of thing, for instance, prediction-error minimization mechanisms. The final section focuses on one of the central functions of the cognitive self: to engage in conscious reasoning. It is argued that the phenomenon of conscious, deliberate reasoning poses an apparently insoluble problem for a PP-based view, one that seems to rest on a structural limitation of predictive-processing models. In a nutshell, conscious reasoning is a single-stream phenomenon, but, in order for PP to apply, two streams of activity must be involved, a prediction stream and an input stream. Thus, with regard to the question of the nature of the self, PP-based views must yield to an alternative approach, regardless of whether proponents of the predictive processing, as a comprehensive theory of cognition, can handle the various empirical challenges canvassed in the preceding section.

In this paper we distinguish two issues that are often run together in discussions about physicalism. The first issue concerns levels. How do entities picked out by non-physical terminology, such as biological or psychological terminology, relate to physical entities? Are the former identical to, or metaphysically supervenient on, the latter? The second issue concerns physical parts and wholes. How do macroscopic physical entities relate to their microscopic parts? Are the former generally determined by the latter? We argue that views on (...) these two issues are independent of one another and should not be conflated. (shrink)

Causation is one of philosophy's most venerable and thoroughly-analyzed concepts. However, the study of how ordinary people make causal judgments is a much more recent addition to the philosophical arsenal. One of the most prominent views of causal explanation, especially in the realm of harmful or potentially harmful behavior, is that unusual or counternormative events are accorded privileged status in ordinary causal explanations. This is a fundamental assumption in psychological theories of counterfactual reasoning, and has been transported to philosophy by (...) Hitchcock and Knobe (2009). A different view--the basis of the culpable control model of blame (CCM)--is that primary causal status is accorded to behaviors that arouse negative evaluative reactions, including behaviors that stem from nefarious motives, negligence or recklessness, a faulty character, or behaviors that lead to harmful or potentially harmful consequences. This paper describes four empirical studies that show consistent support for the CCM. (shrink)

The role of autobiographical memory is not just to relate us to our past self, but also to shape the future self of ours by helping us navigate the complex world we encounter in our every-day lives on a stable basis: some more or less vivid idea of who we really are as persons, as individual beings with distinct selves and unique identities. In this sense memory has also to do with being and becoming, and not just with having been. (...) The advances in the field of memory neuroscience have resulted in what is called memory reconsolidation, that is, techniques to suppress, modify, or enhance certain memories that have to do with our moral identity and moral status. In this presentation I will discuss certain potential implications of memory reconsolidation that are in my view of key importance for neuroethics, and especially for the debate concerning moral identity, agency and status in the brand-new landscape that has been shaped by the novel capabilities neuroscience has made available.

If I were asked to put forward an ethical principle which I considered to be especially certain, it would be that no one can be responsible, in the properly ethical sense, for the conduct of another. Responsibility belongs essentially to the individual. The implications of this principle are much more far-reaching than is evident at first, and reflection upon them may lead many to withdraw the assent which they might otherwise be very ready to accord to this view of responsibility. (...) But if the difficulties do appear to be insurmountable, and that, very certainly, does not seem to me to be the case, then the proper procedure will be, not to revert to the barbarous notion of collective or group responsibility, but to give up altogether the view that we are accountable in any distinctively moral sense.

Have you ever thought about how self-consciousness (self-awareness) originated in the universe? Understanding consciousness is one of the toughest "nuts to crack." In recent years, scientists and philosophers have attempted to provide an answer to this mystery. The reason for this is simply because it cannot be confined to solely a materialistic interpretation of the world. Some scientific materialists have suggested that consciousness is merely an illusion in order to insulate their worldviews. Yet, consciousness is the most fundamental thing we (...) know, even more so than the external world since we require it to perceive or think about anything. Without it, reasoning would be impossible. Dr. Scott Ventureyra, in this ground-breaking book, explores the idea of the Christian God and Creation in order to tackle this most difficult question. He demonstrates that theology has something significant to offer in reflection of how consciousness originated in the universe. He also makes a modest claim that the Christian conception of God and Creation provide a plausible account for the origin of self-consciousness. He integrates philosophy, theology, and science in an innovative way to embark on this exploration. (shrink)

Moral philosophers are, among other things, in the business of constructing moral theories. And moral theories are, among other things, supposed to explain moral phenomena. Consequently, one’s views about the nature of moral explanation will influence the kinds of moral theories one is willing to countenance. Many moral philosophers are (explicitly or implicitly) committed to a deductive model of explanation. As I see it, this commitment lies at the heart of the current debate between moral particularists and moral generalists. In (...) this paper I argue that we have good reasons to give up this commitment. In fact, I show that an examination of the literature on scientific explanation reveals that we are used to, and comfortable with, non-deductive explanations in almost all areas of inquiry. As a result, I argue that we have reason to believe that moral explanations need not be grounded in exceptionless moral principles. (shrink)

The article begins by describing two longstanding problems associated with direct inference. One problem concerns the role of uninformative frequency statements in inferring probabilities by direct inference. A second problem concerns the role of frequency statements with gerrymandered reference classes. I show that past approaches to the problem associated with uninformative frequency statements yield the wrong conclusions in some cases. I propose a modification of Kyburg’s approach to the problem that yields the right conclusions. Past theories of direct inference have (...) postponed treatment of the problem associated with gerrymandered reference classes by appealing to an unexplicated notion of projectability . I address the lacuna in past theories by introducing criteria for being a relevant statistic . The prescription that only relevant statistics play a role in direct inference corresponds to the sort of projectability constraints envisioned by past theories. (shrink)

Homeostatic property clusters (HPCs) are offered as a way of understanding natural kinds, especially biological species. I review the HPC approach and then discuss an objection by Ereshefsky and Matthen, to the effect that an HPC qua cluster seems ill-fitted as a description of a polymorphic species. The standard response by champions of the HPC approach is to say that all members of a polymorphic species have things in common, namely dispositions or conditional properties. I argue that this response fails. (...) Instances of an HPC kind need not all be similar in their exhibited properties. Instead, HPCs should instead be understood as unified by the underlying causal mechanism that maintains them. The causal mechanism can both produce and explain some systematic differences between a kind’s members. An HPC kind is best understood not as a single cluster of properties maintained in stasis by causal forces, but as a complex of related property clusters kept in relation by an underlying causal process. This approach requires recognizing that taxonomic systems serve both explanatory and inductive purposes. (shrink)

There are two senses of ‘what scientists know’: An individual sense (the separate opinions of individual scientists) and a collective sense (the state of the discipline). The latter is what matters for policy and planning, but it is not something that can be directly observed or reported. A function can be defined to map individual judgments onto an aggregate judgment. I argue that such a function cannot effectively capture community opinion, especially in cases that matter to us.

This paper explains how to use a new software tool for argument diagramming available free on the Internet, showing especially how it can be used in the classroom to enhance critical thinking in philosophy. The user loads a text file containing an argument into a box on the computer interface, and then creates an argument diagram by dragging lines from one node to another. A key feature is the support for argumentation schemes, common patterns of defeasible reasoning historically know as (...) topics . Several examples are presented, as well as the results of an experiment in using the system with students in a university classroom. (shrink)

Concept representation is still an open problem in the field of ontology engineering and, more generally, of knowledge representation. In particular, the issue of representing “non classical” concepts, i.e. concepts that cannot be defined in terms of necessary and sufficient conditions, remains unresolved. In this paper we review empirical evidence from cognitive psychology, according to which concept representation is not a unitary phenomenon. On this basis, we sketch some proposals for concept representation, taking into account suggestions from psychological research. In (...) particular, it seems that human beings employ both prototype-based and exemplar-based representations in order to represent non classical concepts. We suggest that a similar, hybrid prototype-exemplar based approach could also prove useful in the field of knowledge representation technology. Finally, we propose conceptual spaces as a suitable framework for developing some aspects of this proposal. (shrink)

In a recent article, Joel Pust argued that direct inference based on reference properties of differing arity are incommensurable, and so direct inference cannot be used to resolve the Sleeping Beauty problem. After discussing the defects of Pust's argument, I offer reasons for thinking that direct inferences based on reference properties of differing arity are commensurable, and that we should prefer direct inferences based on logically stronger reference properties, regardless of arity.

Robert Kimball, in “What’s Wrong with Argumentum Ad Baculum?” (Argumentation, 2006) argues that dialogue-based models of rational argumentation do not satisfactorily account for what is objectionable about more malicious uses of threats encountered in some ad baculum arguments. We review the dialogue-based approach to argumentum ad baculum, and show how it can offer more than Kimball thinks for analyzing such threat arguments and ad baculum fallacies.

The badness of having conflicting emotions is a familiar theme in academic ethics, clinical psychology, and commercial self-help, where emotional harmony is often put forward as an ideal. Many philosophers give emotional harmony pride of place in their theories of practical reason.1 Here we offer a defense of a particular species of emotional conflict, namely, ambivalence. We articulate an conception of ambivalence, on which ambivalence is unresolved inconsistent desire (§1) and present a case of appropriate ambivalence (§2), before considering two (...) alternative defenses of emotional conflict (§3). We then argue that inconsistent desires can be fitting (§4) and that it can be reasonable not to resolve inconsistent desires (§5), before considering an objection (§6) and concluding the discussion (§7).

Daniel Dennett (1996) has disputed David Chalmers' (1995) assertion that there is a "hard problem of consciousness" worth solving in the philosophy of mind. In this paper I defend Chalmers against Dennett on this point: I argue that there is a hard problem of consciousness, that it is distinct in kind from the so-called easy problems, and that it is vital for the sake of honest and productive research in the cognitive sciences to be clear about the difference. But I (...) have my own rebuke for Chalmers on the point of explanation. Chalmers (1995, 1996) proposes to "solve" the hard problem of consciousness by positing qualia as fundamental features of the universe, alongside such ontological basics as mass and space-time. But this is an inadequate solution: to posit, I will urge, is not to explain. To bolster this view, I borrow from an account of explanation by which it must provide "epistemic satisfaction" to be considered successful (Rowlands, 2001; Campbell, 2009), and show that Chalmers' proposal fails on this account. I conclude that research in the science of consciousness cannot move forward without greater conceptual clarity in the field. (shrink)

According to standard scientific realism, science seeks truth and we can justifiably believe that our successful theories achieve, or at least approximate, that goal. In this paper, I discuss the implications of the following competitor thesis: Any theory we may favor has competitors such that we cannot justifiably deny that they are approximately true. After defending that thesis, I articulate three specific threats it poses for standard scientific realism; one is epistemic, the other two are axiological (that is, pertaining to (...) the claim that science seeks truth). I also flag an additional axiological “challenge,” that of how one might justify the pursuit of a primary aim, such as truth. Bracketing epistemic realism, I argue that the axiological threats can be addressed by embracing a refined realist axiological hypothesis, one that specifies a specific subclass of true claims sought in science. And after identifying three potential responses to the axiological “challenge,” I contend that, while standard axiological realism appears to lack the resources required to utilize any of the responses, the refined realist axiology I embrace is well suited to each.

We present an original emergent individuals view of human persons, on which persons are substantial biological unities that exemplify metaphysically emergent mental states. We argue that this view allows for a coherent model of identity-preserving resurrection from the dead consistent with orthodox Christian doctrine, one that improves upon alternatives accounts recently proposed by a number of authors. Our model is a variant of the “falling elevator” model advanced by Dean Zimmerman that, unlike Zimmerman’s, does not require a closest continuer account (...) of personal identity. We end by raising some remaining theological concerns. (shrink)

V tomto článku se zamýšlím nad možností „správné“ (objektivní, adekvátní) interpretace Dao De Jingu (DDJ). Zamyšlení nad „komunikační situací“ vede k rozlišení několika základních prvků (autor, text, interpret, adresát). K jednotlivým prvkům stručně shrnuji současný stav interpretačního úsilí odborníků na DDJ (opíraje se především o článek A. Chana). Kontroverzní povaha výsledků současného bádání nás nemá vést ke skepticismu „integrativní hermeneutiky“, která na adekvátní interpretaci rezignuje. Je možné se i nadále držet principů „rekonstruktivní hermeneutiky“, která spatřuje adekvátní interpretaci jakožto svůj cíl.

La logica modale è nata per studiare i ragionamenti su ciò che è possibile e ciò che è necessario. Negli ultimi decenni, a partire dal lavoro di logici e filosofi quali Rudolf Carnap, Saul Kripke e David Lewis, la sua applicazione è stata progressivamente estesa ad altri ambiti, quali il ragionamento sul tempo, sulla conoscenza e sui sistemi di norme. Queste ricerche hanno condotto a un complesso e intrigante dialogo con alcune fondamentali branche della filosofia: la metafisica, l’epistemologia, la filosofia (...) del linguaggio. Lo scopo del volume è offrire una panoramica di questo dialogo al contempo accessibile e rigorosa, pensata sia per gli studenti di un corso universitario, sia per il lettore non specialista. Se da un lato tutte le necessarie nozioni tecniche sono rese accessibili ai non addetti ai lavori, dall'altro si restituisce un'immagine fedele delle sfide concettuali che la ricerca in questi settori è oggi chiamata ad affrontare.

Several authors have claimed that prediction is essentially impossible in the general theory of relativity, the case being particularly strong, it is said, when one fully considers the epistemic predicament of the observer. Each of these claims rests on the support of an underdetermination argument and a particular interpretation of the concept of prediction. I argue that these underdetermination arguments fail and depend on an implausible explication of prediction in the theory. The technical results adduced in these arguments can be (...) related to certain epistemic issues, but can only be misleadingly or mistakenly characterized as related to prediction. (shrink)

Until recently Francisco Suárez (1548–1617) has been regarded as the “last medieval philosopher,” representing the end of the philosophically respectful scholastic tradition going back to the Early Middle Ages. In fact, however, Suárez stood at the beginning, rather than at the end, of a distinguished scholastic culture, which should best be labeled “Baroque scholasticism,” and which flourished throughout the seventeenth and early eighteenth centuries. In this paper I offer some ideas on why the study of this philosophical culture has been (...) so far neglected by the mainstream Anglo-American philosophical historiography and argue that more attention should be paid to it.

Embodiment matters to perception and action. Beyond the triviality that, under normal circumstances, we need a body in order to perceive the world and act in it, our particular embodiment, right here, right now, both enables and constrains our perception of possibilities for action. In this chapter, we provide empirical support for the idea that the structural and morphological features of the body can narrow the set of our possible interactions with the environment by shaping the way we perceive the (...) possibilities for action provided. We argue that this narrowing holds true in the perception of what we call strongly embodied affordances, that is, relevant micro-affordances that have a genuinely demanding characteristic, as well as in the perception of actions performed by others. In particular, we show that perceptual contents are shaped by fine-grained morphological features of the body, such as specific hand-shapes, and that they change according to our possibility to act upon them with this body, in this situation, at this moment. We argue that these considerations provide insight into distinguishing a variety of experienced affordance relations that can aid us in better understanding the relevance of embodiment for perception and experience.

The research was generally motivated by a dearth of studies on joy, and particularly inspired by a book of joy celebrating the inter-spiritual dialogue between the Dalai Lama and Desmond Tutu. Its aim was to investigate whether the direct contemplation of joy would be associated with improvements in psychophysiological coherence, spirituality and various positive emotions and feelings. Integrative quantitative and qualitative findings emerging from a small pilot study, including a convenience sample of six participants with a mean age of 42 (...) years and age range of 25-69 years, supported the research hypothesis. Significant quantitative increases in psychophysiological coherence, spirituality and positive feelings were coherently and consistently supported by participants' individual and collective experiences. Integrative discussion amplified the paradoxical theme of joy through suffering in human emotional and spiritual life. (shrink)
