This is a transcript of a conversation between P F Strawson and Gareth Evans in 1973, filmed for The Open University. Under the title 'Truth', Strawson and Evans discuss the question as to whether the distinction between genuinely fact-stating uses of language and other uses can be grounded on a theory of truth, especially a 'thin' notion of truth in the tradition of F P Ramsey.

Over the past decades, the idea that national sovereignty and the authority of the state have been increasingly challenged or even substantially eroded has been a dominant one. Economic globalization advancing a neo-liberal dis-embedding of the economy is seen as the major reason for this erosion. Concerns have increased about the negative consequences for the social fabric of societies, deprived of the strong shock absorption capacity that the welfare states had established in the time of the embedded liberalism to use (...) a term John Ruggie coined. The concerns have also helped nationalistic movements to gain power in many high-income countries, not at least in the United States, calling for putting their economy first. Accordingly, a number of commentators have announced a return of the nation state. In this special issue, we will show that the retreat-of-the-state thesis as well as the return-of-the-state thesis shares the same shortcomings. They conflate state and authority. As a consequence, both theses underestimate important transformations of authority that have taken place since the end of the “short 20TH century,” to use Eric Hobsbawm's periodization. With this special issue, we seek to contribute to a more nuanced analysis of the transformation of authority. The issue is the outcome of a conference that took place at the Copenhagen Business School in 2015, hosted by the research project ‘Institutional Transformation in European Political Economy: A Socio-Legal Approach’ and funded by the European Research Council.

This book develops the law of political economy as a new field of scholarly enquiry. Bringing together an exceptional group of scholars, it provides a novel conceptual framework for studying the role of law and legal instruments in political economy contexts, with a focus on historical transformations and central challenges in both European and global contexts. Its chapters reconstruct how the law of political economy plays out in diverse but central fields, ranging from competition and consumer protection law to labour (...) and environmental law, giving a comprehensive overview of the central challenges of the law of political economy. It also provides a sophisticated and multifaceted framework for further enquires while outlining the contours of new law of political economy. (shrink)

Summary: A review of the cognitivist/extended cognition and extended mind landscape.

Internalism about moral responsibility is the view that moral responsibility is determined primarily by an agent's mental states; externalism is the view that moral responsibility is determined primarily by an agent's overt behaviour and by circumstances external to the agent. In a series of papers, Michelle Ciurria has argued that most if not all current accounts of moral responsibility, including Strawsonian ones, are internalist. Ciurria defends externalism against these accounts, and she argues that, in contrast to his contemporary followers, P.F. (...) Strawson himself was an externalist. I believe that Ciurria's reading of Strawson is problematic. The aim of this paper is to elucidate Strawson's position with regard to the internalism-externalism issue against the background of Ciurria's reading of him. I conclude that Strawson was neither an internalist nor an externalist about moral responsibility. I draw extensively upon the whole body of Strawson's work, much of which is sadly neglected in discussions of ‘Freedom and Resentment’, although it illuminates many of the issues discussed there.

E. F. Carritt (1876-1964) was educated at and taught in Oxford University. He made substantial contributions both to aesthetics and to moral philosophy. The focus of this entry is his work in moral philosophy. His most notable works in this field are The Theory of Morals (1928) and Ethical and Political Thinking (1947). Carritt developed views in metaethics and in normative ethics. In meta-ethics he defends a cognitivist, non-naturalist moral realism and was among the first to respond to A. J. (...) Ayer’s emotivist challenge to this view. In normative ethics he advocates a deontological view in which there is a plurality of obligations and of non-instrumental goods. In the context of defending this view he raised some penetrating and novel criticisms of ideal utilitarianism. He held that it is not acceptable to revise our reflective common-sense moral attitudes in the face of philosophical moral theories, and that moral philosophy is only indirectly practical. (shrink)

I present a possible worlds semantics for a hyperintensional belief revision operator, which reduces the logical idealization of cognitive agents affecting similar operators in doxastic and epistemic logics, as well as in standard AGM belief revision theory. (Revised) belief states are not closed under classical logical consequence; revising by inconsistent information does not perforce lead to trivialization; and revision can be subject to ‘framing effects’: logically or necessarily equivalent contents can lead to different revisions. Such results are obtained without resorting (...) to non-classical logics, or to non-normal or impossible worlds semantics. The framework combines, instead, a standard semantics for propositional S5 with a simple mereology of contents. (shrink)

Despite his impressive influence on nineteenth-century philosophy, F. A. Trendelenburg's own philosophy has been largely ignored. However, among Kant scholars, Trendelenburg has always been remembered for his feud with Kuno Fischer over the subjectivity of space and time in Kant's philosophy. The topic of the dispute, now frequently referred to as the ?Neglected Alternative? objection, has become a prominent issue in contemporary discussions and interpretations of Kant's view of space and time. The Neglected Alternative contends that Kant unjustifiably moves from (...) the claim that we have a priori intuitions of space and time to the sceptical conclusion that space and time are exclusively subjective. Most current discussions trace the objection back to Trendelenburg and often use him to motivate the objection. However, to date Trendelenburg's actual arguments and reasons for rejecting the Kantian view of space and time have not been sufficiently uncovered; my goal here is to fill this lacuna. By better understanding what Trendelenburg actually argued, we will be in a better position to assess whether the Neglected Alternative objection against Kant is successful. But in addition, Trendelenburg's own system is of independent philosophical interest, and my work here will shed light on one part of it. (shrink)

Esta coletânea é um tributo a Peter Frederick Strawson pelo centenário de seu nascimento (1919-2019). Diferentemente de outras coletâneas, esta propõe colocar em relevo a interlocução de Strawson com a tradição filosófica. Em outras palavras, por um lado, queremos evidenciar as discussões que Strawson travou com os seus contemporâneos (Austin, Quine, Russell e Wittgenstein), e, por outro, a influência que recebeu e as críticas que dirigiu àqueles que o precederam na história da filosofia (Aristóteles, Descartes, Hume, Kant). Poderíamos ter enriquecido (...) a lista acima com o nome de muitos outros filósofos com os quais Strawson teve contato, mas julgamos que o trabalho ficaria bastante extenso. Por esse motivo, optamos por aqueles nomes mais significativos que figuram na construção da história intelectual de Strawson. O presente volume reúne nove capítulos que levam como título o nome de Strawson e do filósofo com o qual ele dialogou ao longo de suas obras. Essa opção na nomeação dos capítulos por si só já permite colocar em evidência os principais filósofos pelos quais Strawson se interessou e com os quais se confrontou ao longo de seu trabalho filosófico. Com exceção do capítulo sobre Wittgenstein, que é uma versão revisada de um texto publicado anteriormente, todos os outros capítulos são inéditos e foram escritos especialmente para esta coletânea. O volume inclui na abertura a tradução de “Um fragmento de autobiografia intelectual”, de P. F. Strawson. Quando elegemos como título desta obra, Strawson e a tradição filosófica, não estamos insinuando que Strawson é um historiador da filosofia e muito menos que se interesse por historiografia. O título desta obra apenas quer indicar que Strawson, por um lado, transita na história da filosofia com alguma facilidade, além de nutrir um grande apreço por ela e, por outro, que ele discute com os principais nomes da história da filosofia no que concerne aos temas de seu interesse. A sua proposta filosófica é alimentada e irrigada por esse conhecimento, o que lhe dá a possibilidade de assumir na maioria das vezes posições ponderadas e equilibradas acerca de temas complexos por ele tratados. ​ ISBN: 978-85-5696-689-6.

Abortion bans have been characterized as cruel especially in not allowing exceptions for rape or incest. The article first examines one approach to morally justifying bans based on the Doctrine of Double Effect (DDE) which distinguishes morally between killing or letting die intending death versus doing so only foreseeing death. It then presents some criticisms of the implications of the DDE but also argues that what the doctrine permits helps provide a ground for the permissibility of abortions even if the (...) fetus is a person. Whether there are limits on applying this argument is also considered. In conclusion, the article considers whether and why not permitting exceptions to bans for rape and incest is cruel and whether cruelty is a ground for opposition to bans. (shrink)

Årets Hägerströmföreläsningar i Uppsala gavs i februari av den norske filosofen Dagfinn Føllesdal. Ämnet var "Mening og Erfaring". Dagfinn Føllesdal doktorerade 1961 vid Harvard med Willard Van Quine som handledare på en avhandling om kvantifierad modallogik. Han blev internationellt känd främst för studier om Husserls fenomenologi och dess förhållande till Frege samt för sina arbeten om Quines språkfilosofi. Allt sedan 60-talet har Føllesdal delat sin tid mellan Oslouniversitetet och Stanforduniversitetet i Kalifornien. I sina föreläsningar diskuterade Føllesdal meningsbegreppet med anknytning till (...) teorier formulerade av sådana tidigare Hägerströmföreläsare som Quine, Davidson och Kripke. En utgångspunkt för framställningen var Quines empiristiska syn på språket: Allt vi kan lära om omvärlden och varandra, inklusive språket, är grundat på socialt tillgänglig evidens. Enligt Quines uppfattning är språket väsentligen ett socialt fenomen. Detta innebär att: (i) språket har blivit till genom en social process; (ii) individens inlärning av språket sker på basen av socialt tillgänglig information; och (iii) användningen av språket är en social process. Den centrala frågeställningen som diskuterades i föreläsningarna var: Hur skall vi utifrån en empiristisk syn på språket förstå mening och kommunikation? Quine var den förste att på ett helt explicit sätt formulera denna problemställning. (shrink)

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)

Existing research suggests that people's judgments of actual causation can be influenced by the degree to which they regard certain events as normal. We develop an explanation for this phenomenon that draws on standard tools from the literature on graphical causal models and, in particular, on the idea of probabilistic sampling. Using these tools, we propose a new measure of actual causal strength. This measure accurately captures three effects of normality on causal judgment that have been observed in existing studies. (...) More importantly, the measure predicts a new effect ("abnormal deflation"). Two studies show that people's judgments do, in fact, show this new effect. Taken together, the patterns of people's causal judgments thereby provide support for the proposed explanation. (shrink)

I agree that Wollheim is wrong in his reconstruction of Bradley's arguments on Subject-Predicate judgements, but not completely. Wollheim is right about the conclusion of Bradley's arguments. I argue that Bradley does not reject subject-predicate form of judgements rather he attack's the idea that there is some judgement in which the subject is the nude reality.

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.

According to one large family of views, scientific explanations explain a phenomenon (such as an event or a regularity) by subsuming it under a general representation, model, prototype, or schema (see Bechtel, W., & Abrahamsen, A. (2005). Explanation: A mechanist alternative. Studies in History and Philosophy of Biological and Biomedical Sciences, 36(2), 421–441; Churchland, P. M. (1989). A neurocomputational perspective: The nature of mind and the structure of science. Cambridge: MIT Press; Darden (2006); Hempel, C. G. (1965). Aspects of scientific (...) explanation. In C. G. Hempel (Ed.), Aspects of scientific explanation (pp. 331–496). New York: Free Press; Kitcher (1989); Machamer, P., Darden, L., & Craver, C. F. (2000). Thinking about mechanisms. Philosophy of Science, 67(1), 1–25). My concern is with the minimal suggestion that an adequate philosophical theory of scientific explanation can limit its attention to the format or structure with which theories are represented. The representational subsumption view is a plausible hypothesis about the psychology of understanding. It is also a plausible claim about how scientists present their knowledge to the world. However, one cannot address the central questions for a philosophical theory of scientific explanation without turning one’s attention from the structure of representations to the basic commitments about the worldly structures that plausibly count as explanatory. A philosophical theory of scientific explanation should achieve two goals. The first is explanatory demarcation. It should show how explanation relates with other scientific achievements, such as control, description, measurement, prediction, and taxonomy. The second is explanatory normativity. It should say when putative explanations succeed and fail. One cannot achieve these goals without undertaking commitments about the kinds of ontic structures that plausibly count as explanatory. Representations convey explanatory information about a phenomenon when and only when they describe the ontic explanations for those phenomena. (shrink)

Neuroscience has studied deductive reasoning over the last 20 years under the assumption that deductive inferences are not only de jure but also de facto distinct from other forms of inference. The objective of this research is to verify if logically valid deductions leave any cerebral electrical trait that is distinct from the trait left by non-valid deductions. 23 subjects with an average age of 20.35 years were registered with MEG and placed into a two conditions paradigm (100 trials for (...) each condition) which each presented the exact same relational complexity (same variables and content) but had distinct logical complexity. Both conditions show the same electromagnetic components (P3, N4) in the early temporal window (250–525 ms) and P6 in the late temporal window (500–775 ms). The significant activity in both valid and invalid conditions is found in sensors from medial prefrontal regions, probably corresponding to the ACC or to the medial prefrontal cortex. The amplitude and intensity of valid deductions is significantly lower in both temporal windows (p = 0.0003). The reaction time was 54.37% slower in the valid condition. Validity leaves a minimal but measurable hypoactive electrical trait in brain processing. The minor electrical demand is attributable to the recursive and automatable character of valid deductions, suggesting a physical indicator of computational deductive properties. It is hypothesized that all valid deductions are recursive and hypoactive. (shrink)

A new non-Archimedean approach to interacted quantum fields is presented. In proposed approach, a field operator φ(x,t) no longer a standard tempered operator-valued distribution, but a non-classical operator-valued function. We prove using this novel approach that the quantum field theory with Hamiltonian P(φ)_4 exists and that the corresponding C^*­ algebra of bounded observables satisfies all the Haag-Kastler axioms except Lorentz covariance. We prove that the λ(φ^4 )_4 quantum field theory model is Lorentz covariant.

In Pietroski ( 2018 ) a simple representation language called SMPL is introduced, construed as a hypothesis about core conceptual structure. The present work is a study of this system from a logical perspective. In addition to establishing a completeness result and a complexity characterization for reasoning in the system, we also pinpoint its expressive limits, in particular showing that the fourth corner in the square of opposition (“ Some_not ”) eludes expression. We then study a seemingly small extension, called (...) SMPL +, which allows for a minimal predicate-binding operator. Perhaps surprisingly, the resulting system is shown to encode precisely the concepts expressible in first-order logic. However, unlike the latter class, the class of SMPL + expressions admits a simple procedural (context-free) characterization. Our contribution brings together research strands in logic—including natural logic, modal logic, description logic, and hybrid logic—with recent advances in semantics and philosophy of language.

La psicología contemporánea parece caracterizarse desde sus propios orígenes por la multiplicidad de sus contenidos, además de por su casi infinita fragmentación en corrientes encontradas. Esto crea importantes dificultades, no sólo a quienes quieran tener una primera aproximación, sino también a los especialistas, que muchas veces no llegan a una opinión suficientemente clara sobre la naturaleza epistemológica de la psicología, ni sobre su unidad disciplinar. Esta obra, sin descuidar el problema global, se centra en un aspecto particular: el que presenta (...) la praxis de la psicología, en particular la psicoterapia y sus fundamentos teóricos. Se pone especial interés en una visión crítica del psicoanálisis, punto de referencia inevitable (positivo o negativo) para la mayoría de las corrientes de psicoterapia. Pero este intento de esclarecimiento epistemológico y práctico se lleva a cabo desde un punto de vista original: a la luz del pensamiento de Santo Tomás de Aquino (1225-1274), conocido como uno de los más grandes teólogos y filósofos de la Iglesia Católica. Las calidades del Aquinate como epistemológico son sobradamente conocidas. Menos conocida es su faceta de psicólogo, que esta obra quiere poner de manifiesto con gran detalle para evidenciar la actualidad de las líneas maestras de la psicología de Santo Tomás, como también la posibilidad de practicar hoy la psicología bajo la guía fundamental del Doctor Humanitatis.\n.

The biological sciences study (bio)complex living systems. Research directed at the mechanistic explanation of the "live" state truly requires a pluralist research program, i.e. BioComplexity research. The program should apply multiple intra-level and inter-level theories and methodologies. We substantiate this thesis with analysis of BioComplexity: metabolic and modular control analysis of metabolic pathways, emergence of oscillations, and the analysis of the functioning of glycolysis.

Brentano claims to have taken his idea of intentionality from scholastic thought. However, in St. Thomas Aquinas, intentionality is not just the mark of knowledge, although some scholastics have interpreted it this way, even during Brentano’s lifetime. Moreover, to elaborate his idea of intentional presence, the German philosopher was not only inspired by him, but also by Francisco Suárez. In an unpublished manuscript from his legacy, Brentano understands Suarez’s objective concept as a representation of the thing in the psyche. Thus, (...) even before writing his definitive doctoral thesis, Brentano maintained that the object of thought is not the external thing but its mental copy. In short, modern philosophy seems to have been more decisive than scholasticism in shaping the substance of his theory of intentionality. (shrink)

This paper is an investigation of the general logic of "identifications", claims such as 'To be a vixen is to be a female fox', 'To be human is to be a rational animal', and 'To be just is to help one's friends and harm one's enemies', many of which are of great importance to philosophers. I advocate understanding such claims as expressing higher-order identity, and discuss a variety of different general laws which they might be thought to obey. [New version: (...) Nov. 4th, 2016].

The language of phenomenology includes terms such as intentionality, phenom- enon, insight, analysis, sense, not to mention the key term of Edmund Husserl’s manifesto, “the things themselves” to return to . But what does the “things them- selves” properly mean? How come the term is replaced by the “findings” over time? And what are the findings for? The investigation begins by looking at the tricky legacy of the modern turn, trying to clarify ties to past masters, including Francis- co Suárez (...) and Augustine of Hippo . The former, because his influence goes beyond René Descartes reaching undoubtedly Franz Brentano and his students, as well as Martin Heidegger . The latter, because Augustine gives a personal component to the Greek inheritance, marked by the “inward turn .” However, it would not be possible to review the history of thought without the help offered by Jan Patočka's analyses . Patočka discloses the “care” of the Greek philosophers, Plato and Dem- ocritus among others, “for the soul”, we would say with Patočka for “being,” whose sense “does not leave us indifferent” as the leitmotiv of Ancient Philosophy . Nev- ertheless, in his lectures on Plato and Europe, Patočka points out that you must be careful not to confuse the phenomena of things, of existens, with the phenomena of being . Finally, Patočka’s legacy is found in the efforts to reconcile the life-feeling with the modern construction of reality, which means “a radical reconstruction of the naive and natural world of common sense .” In some ways, intentionality is to be revised .

The paper deals with Weizsäcker’s position within the philosophy of mind. It turns out that Weizsäcker’s ontology is based on an unorthodox conception both in the philosophy of physics and in the philosophy of mind. His quantum information theoretic reductionism is based on a subtle combination of atomism and holism, his philosophy of mind connected to this is a neutral monism, which proposes a bold intertwining of mind, matter, and space.

Eastern philosophy and western science have convergent and divergent viewpoints for their explanation of consciousness. Convergence is found for the practice of meditation allowing besides a time dependent consciousness, the experience of a timeless consciousness and its beneficial effect on psychological wellbeing and medical improvements, which are confirmed by multiple scientific publications. Theories of quantum mechanics with non-locality and timelessness also show astonishing correlation to eastern philosophy, such as the theory of Penrose-Hameroff (ORC-OR), which explains consciousness by reduction of quantum (...) superposition in the brain. Divergence appears in the interpretation of the subjective experience of timeless consciousness. In eastern philosophy, meditation at a higher level of awareness allows the personal experience of timeless and non-dual consciousness, considered as an empirical proof for the existence of pure consciousness or spirituality existing before the material world and creating it by design. Western science acknowledges the subjective, non-dual experience, and its multiple beneficial effects, however, the interpretation of spirituality designing the material universe is in disagreement with the Darwinian Theory of mutation and selection. A design should create an ideal universe without the injustice of 3% congenital birth defects and later genetic health problems. The western viewpoint of selection is more adapted to explain congenital errors. The gap between subjectivity and objectivity, the mind-body problem, is in eastern philosophy reduced to the dominance of subjectivity over objectivity, whereas western science attributes equal values to both. Nevertheless, there remains an astonishing complementarity between eastern and western practices. (shrink)

This article considers some different views of fairness and whether they conflict with the use of a version of Cost Effectiveness Analysis (CEA) that calls for maximizing health benefits per dollar spent. Among the concerns addressed are whether this version of CEA ignores the concerns of the worst off and inappropriately aggregates small benefits to many people. I critically examine the views of Daniel Hausman and Peter Singer who defend this version of CEA and Eric Nord among others who criticize (...) it. I come to focus in particular on the use of CEA in allocating scarce resources to the disabled. (shrink)

Effective altruism is a movement which aims to maximise good. Effective altruists are concerned with extreme poverty and many of them think that individuals have an obligation to donate to effective charities to alleviate extreme poverty. Their reasoning, which I will scrutinise, is as follows: -/- Premise 1. Extreme poverty is very bad. -/- Premise 2. If it is in our power to prevent something very bad from happening, without thereby sacrificing anything else morally significant, we ought, morally, to do (...) it. -/- Premise 3. Individuals ought to choose the effective option in preventing very bad things. -/- Premise 4. Donating to effective charities is one of the best ways to alleviate extreme poverty. -/- Conclusion. Individuals ought to donate to effective charities working towards extreme poverty alleviation where doing so does not require them to give up anything of moral significance. -/- I will scrutinise each of these premises in turn. -/- For Premise 1, I focus on hedonistic utilitarianism and criticise its outlook on extreme poverty. I claim that hedonistic utilitarianism might be problematic for effective altruism. -/- Premise 2 is Peter Singer's Weaker Principle of Sacrifice. I introduce several possible interpretations of it, and press several objections to it by stressing overpermissiveness, luck, and rights. I defend strengthening the Weaker Principle of Sacrifice without making it overdemanding. -/- I claim that Premise 3 can be attractive to both consequentialists and non-consequentialists. Nevertheless, by showing that effectiveness sometimes violates fairness, I propose a method which avoids always helping the greater number and always giving everyone equal chances of being helped, which is compatible with effective altruism. -/- Against Premise 4, I assess the systemic change objection, which states that effective altruism unjustifiably distracts individuals from systemic change. By considering risk and the moral standing of the future extremely poor, I claim that the systemic change objection is partially successful, but cannot undermine effective altruism. -/- After analysing all of these, I argue that individuals have an obligation to donate to effective charities to alleviate extreme poverty where doing so does not require them to give up anything of moral significance.

Článek reflektuje Hayekovy výklady o povaze pravidel. Ukazuje, že jeho pojetí pravidel je extrémně široké a vazba mezi pravidly a pravidelnostmi je nepřijatelně úzká.

In this article it is shown that a careful analysis of Kant 's Gedanken von der wahren Schätzung der lebendigen Kräfte und Beurtheilung der Beweise leads to a conclusion that does not match the usually accepted interpretation of Kant 's reasoning in 1747, according to which the young Kant supposedly establishes a relationship between the tridimensionality of space and Newton's law of gravitation. Indeed, it is argued that this text does not yield a satisfactory explanation of space dimensionality, and actually (...) restricts itself to justifying the tridimensionality of extension. (shrink)

Complex human reasoning involves minimal abilities to extract conclusions implied in the available information. These abilities are considered “deductive” because they exemplify certain abstract relations among propositions or probabilities called deductive arguments. However, the electrophysiological dynamics which supports such complex cognitive pro- cesses has not been addressed yet. In this work we consider typically deductive logico- probabilistically valid inferences and aim to verify or refute their electrophysiological functional connectivity differences from invalid inferences with the same content (same relational variables, same (...) stimuli, same relevant and salient features). We recorded the brain electrophysiological activity of 20 participants (age 1⁄4 20.35 ± 3.23) by means of an MEG system during two consecutive reasoning tasks: a search task (invalid condition) without any specific deductive rules to follow, and a logically valid deductive task (valid condition) with explicit deductive rules as instructions. We calculated the functional connectivity (FC) for each condition and conducted a seed-based analysis in a set of cortical regions of interest. Finally, we used a cluster-based permutation test to compare the dif- ferences between logically valid and invalid conditions in terms of FC. As a first novel result we found higher FC for valid condition in beta band between regions of interest and left prefrontal, temporal, parietal, and cingulate structures. FC analysis allows a second novel result which is the definition of a propositional network with operculo-cingular, parietal and medial nodes, specifically including disputed medial deductive “core” areas. The experiment discloses measurable cortical processes which do not depend on content but on truth-functional propositional operators. These experimental novelties may contribute to understand the cortical bases of deductive processes. (shrink)
