This paper investigates whether 'even if A, B' is pragmatically polysemic, so that a nonconcessive conditional may have 'even if', and whether concessive conditionals, pragmatically defined, can fail to have 'even if' or a non-temporal 'still'. Different paraphrases are used to help elucidate pragmatic meanings. A theory of the pragmatic meanings of concessive and implicative conditionals is presented. The semantic meaning of 'even if' and the question of whether concessive conditionals imply the truth of their consequents are also discussed.

An extended examination of Libet's works led to a comprehensive reinterpretation of his results. According to this reinterpretation, the Minimum Train Duration of electrical brain stimulation should be considered as the time needed to create a brain stimulus efficient for producing conscious sensation and not as a basis for inferring the latency for conscious sensation of peripheral origin. Latency for conscious sensation with brain stimulation may occurafterthe Minimum Train Duration. Backward masking with cortical stimuli suggests a 125-300 ms minimum value (...) for the latency for conscious sensation of threshold skin stimuli. Backward enhancement is not suitable for inferring this latency. For determining temporal relations between stimuli that correspond to subjects' reports, theendof cerebral Minimum Train Duration should be used as reference, rather than its onset. Results of coupling peripheral and cortical stimuli are explained by a latency after the cortical Minimum Train Duration, having roughly the same duration as the latency for supraliminal skin stimuli. Results of coupling peripheral stimuli and stimuli to medial lemniscus (LM) are explained by a shorter LM latency and/or a longer peripheral latency. This interpretation suggests a 230 ms minimum value for the latency for conscious sensation of somatosensory near-threshold stimuli. The backward referral hypothesis, as formulated by Libet, should not be retained. Long readiness potentials preceding spontaneous conscious or nonconscious movements suggest that both kinds of movement are nonconsciously initiated. The validity of Libet's measures of W and M moments (Libet et al., 1983a) is questionable due to problems involving latencies, training, and introspective distinction of W and M. Veto of intended actions may be initially nonconscious but dependent on conscious awareness. (shrink)

In this note, the problem of tracking random references and rejecting random perturbations in a quadrotor, both generated by an auxiliary system named exosystem, is solved by extending the deterministic tracking problem to the area of stochastic processes. Besides, it is considered that only a part of the state vector of the quadrotor is available through measurements. As a consequence, the state vector of the plant must be estimated in order to close the control loop. On this basis, a controller (...) to track random references and to reject random perturbations is developed by combining a Kalman filter to estimate the references and perturbations of an exosystem and an observer to estimate the states of a quadrotor. Besides, to obtain a more practical controller, the analysis is carried out in discrete time. Numerical simulations are used in a quadrotor to confirm the validity and effectiveness of the proposed control. (shrink)

"Tough, smart, superbly engaging, The Material Ghost is a terrific book." -- Edward W. Said In The Material Ghost , Gilberto Perez draws on his lifelong love of the movies as well as his work as a film scholar to write a lively, wide-ranging, penetrating study of films and filmmakers and the nature of the art form. For Perez, film is complex and richly contradictory, lifelike and dreamlike at once, a peculiar mix of reality and imagination. "The images on (...) the screen," he writes, "carry in them something of the world itself, something material, and yet something transposed, transformed into another world: the material ghost." "Dazzling... The sheer intelligence at work in these lucid pages is exhilarating." -- Alfred Guzzetti, Boston Book Review "A pleasure. Gilberto Perez is one of the smartest film critics writing anywhere." -- Jonathan Rosenbaum "Strikes an ideal balance between insightful analysis and graceful writing... A model of thoughtful criticism." -- David Sterritt, Christian Science Monitor "Brilliantly polemical in his critique of cynical reason ('the official philosophy of late capitalism'), no less passionate in defending the truth-value of cinema, Perez seems to be the clearest heir to the great humanist critic André Bazin." -- Sight & amp Sound "The chapters on Keaton and Renoir are stunning, full of perceptive remarks the chapter on Godard is a persuasive rehabilitation none of the chapters is without memorable insights." -- Michael Wood, London Review of Books "Gilberto Perez's ambitious, abundant, and cultivated book--the fruit of decades of thinking and teaching -- accompanies readers on a journey of discovery into the wonder of film." -- Stanley Cavell "Few books of film criticism in the past twenty-five years have been so enjoyable or instructive... [Perez] has excellent things to say about authorship, about documentaries, about popular genres, about cinematic point of view and narrative technique, about actors, and above all about camera style... He makes us want to look once more at the remarkable pictures he discusses." -- James Naremore, Cineaste. (shrink)

Libet's (2000) arguments in defense of his interpretation of his experimental results are insufficient. The claims of my critical review (Gomes, 2008) do not suffer with his new statements.

This book explores the concept of the end of literature through the lens of Hegel's philosophy of art. In his version of Hegel's 'end of art' thesis, Arthur Danto claimed that contemporary art has abandoned its distinctive sensitive and emotive features to become increasingly reflective. Contemporary art has become a question of philosophical reflection on itself and on the world, thus producing an epochal change in art history. The core idea of this book is that this thesis applies quite well (...) to all forms of art except one, namely literature: literature resists its 'end'. Unlike other arts, which have experienced significant fractures in the contemporary world, Campana proposes that literature has always known how to renew itself in order to retain its distinguishing features, so much so that in a way it has always come to terms with its own end. Analysing the distinct character of literature, this book proposes a new and original interpretation of the 'end of art' thesis, showing how it can be used as a key conceptual framework to understand the contemporary novel.

A commentary on articles by Klein, Pockett, and Trevena and Miller, in this issue, is given. Average shift in the point of subjective equality , calculated by Klein on Libet's data, and corresponding change in mean shift, calculated by Libet et al. , may be “corrected,” taking as a reference point the end of the minimum train duration. Values obtained, if significant, indicate a latency for conscious sensation of the skin stimulus of at least 230 ms. Pockett's main conclusions are (...) favored, but her explanation of peripheral–lemniscal couplings is found to be unconvincing. Trevena and Miller's article unsuccessfully tries to rescue a dualist interactionist view. Libet's method of timing intentions is thoroughly criticized. (shrink)

Claims that necessary and sufficient conditions are not converse relations are discussed, as well as the related claim that If A, then B is not equivalent to A only if B . The analysis of alleged counterexamples has shown, among other things, how necessary and sufficient conditions should be understood, especially in the case of causal conditions, and the importance of distinguishing sufficient-cause conditionals from necessary-cause conditionals. It is concluded that necessary and sufficient conditions, adequately interpreted, are converse relations in (...) all cases. (shrink)

A theory of necessary and sufficient conditions is presented, as well as a theory of necessary and sufficient causes and effects, viewed as a particular case of the former. Ambiguities of the terms 'condition' and 'necessary condition' are explored, and a neutral meaning for 'condition' is favoured. The relation between necessary and sufficient conditions and implicative conditionals (including counterfactuals) is also discussed. Two problems of counterfactual theories of causal explanation are indicated, concerning (i) how to account for causes that are (...) not necessary and (ii) how to interpret the counterfactual from the negation of the effect to the negation of the cause. Application of the theory of necessary and sufficient conditions to Euler’s explanation of the Königsberg bridge problem is discussed. The theory of necessary and sufficient causes and effects is then applied to the flagpole shadow explanation and to two biological explanations, one involving a sufficient but not necessary cause and the other a necessary but not sufficient cause. Causes that are neither sufficient nor necessary are also recognized. Finally, a probabilistic approach to causes that are either not sufficient or not necessary is explored, including its application to examples of such cases. (shrink)

L'uomo è un animale razionale, oltreché politico, socievole, come dice Aristotele. Ma quello del pensiero occidentale è un cammino, non sempre lineare, lungo momenti di apertura e ripiegamento della ragione. Quando la ragione è strumento del conoscere è in una fase di apertura, in cui fioriscono le scoperte scientifiche, l'arte, il pensiero politico ed economico; quando invece la stessa ragione perde il suo carattere strumentale divenendo pensiero assoluto, ripiegato su di sé, cede il passo alla follia, fino agli orrori del (...) Nazismo. La follia è il capitolo oscuro di un logos assolutizzato, che non lascia spazio alla molteplicità dei punti di vista, è la deriva di una ragione non 'addomesticata', privata del contraddittorio con il reale. Con un linguaggio preciso ma accessibile, Campana Comparini, al dualismo ragione 'aperta' e feconda/ragione 'chiusa' e assolutizzata, oppone una diversa categoria filosofica di lettura del reale: la follia della croce; ovvero una prospettiva in cui la fede nel Cristo-uomo diventa la base da cui partire per rifondare la principale caratteristica dell'uomo, cioè il pensiero. La 'follia della croce' non è tanto un'alternativa, quanto il terreno su cui reimpiantare la logica della razionalità umana, poiché viene prima di essa. Una lettura per guardare da un'altra prospettiva le origini del pensiero occidentale."--Page 4 of cover. (shrink)

Cinema is commonly hailed as "the universal language," but how does it communicate so effortlessly across cultural and linguistic borders? Drawing on a lifetime's worth of viewing an reviewing, influential critic Gilberto Perez invokes a dizzying array of masters past and present includin Chaplin, Ford, Kiarostami, Eisenstein, Malick, Mizoguchi, Haneke, Hitchcock, and Godard--to explore the transaction between filmmaker and audience. The Eloquent Screen shows how cinema, as the consummate contemporary art form, establishes a thoroughly modern rhetoric in which different (...) points of view are brought into clear focus.".

In the Poetics of Aristotle there is a definition of the human being that perhaps has not yet been well considered in educational theory and practice. This definition calls into question a dynamism that according to Plato was unavoidable for an appropriate understanding of the educational process that turns a human being into a beautiful, good and just citizen: mimesis. The paper's intent is to reconsider the definition of the human being, centred on mimesis, presented by Aristotle in the Poetics (...) to demonstrate if, and how, it might establish new paradigms for human coexistence. Aristotle's anthropological statement is included in a much wider discourse concerning philosophy of art; but if isolated from the context, it is an essential definition of human beings that can be synthesised as follows: human beings are the mimetic animal par excellence, and their process of understanding has a fundamental connection with such excellence. Ignorance and/or negligence of how relevant mimesis might be in the educational process may have decisively contributed to separate human beings from this core aspect of their humanity and therefore produced painful consequences in human coexistence. As long as education does not pay attention to the pedagogical implications of the definition taken from the Poetics, how can human flourishing be safeguarded? I argue that recognition of the centrality of mimesis in the educational process allows human edification to proceed devoid of ideological basis, be it secular or confessional; and overcomes the risk of relativism. Mimesis, formerly recognised by Plato as a link between what is expressed and what really is, is masterfully reinterpreted by Aristotle. Aristotle recognised its positive pedagogic value in the Poetics, and nowadays we can recognise how it offers existential dynamics that restore the vital human relationship between self and other. The sense of this proposal lies in giving mimesis the role it deserves in education, by raising the significance of how coexistence might benefit from a vast human dimension, capable of recognising our humanity beyond our rational capacity.

The free will problem is defined and three solutions are discussed: no-freedom theory, libertarianism, and compatibilism. Strict determinism is often assumed in arguing for libertarianism or no-freedom theory. It assumes that the history of the universe is fixed, but modern physics admits a certain degree of randomness in the determination of events. However, this is not enough for a compatibilist position—which is favored here—since freedom is not randomness. It is the I that chooses what to do. It is argued that (...) the core of the free will problem is what this I is. A materialist view is favored: The I is an activity of the brain. In addition to absence of external and internal compulsion, freedom involves absence of causal sufficiency of influences acting on the I. A more elaborate compatibilist view is proposed, according to which causal determination is complete when we add events occurring in the I (of which the subject is not conscious). Contrary to what several authors have argued, the onset of the readiness potential before the decision to act is no problem here. The experience of agency is incomplete and fallible, rather than illusory. Some consequences of different views about freedom for the ascription of responsibility are discussed. (shrink)

Since the mid-20th century, human beings have become aware of the negative changes that planet Earth is undergoing, some of them produced by themselves and which endanger their existence. One of these changes is the increase in the average temperature caused by the greenhouse effect. The United Nations has taken care of this problem and organized 25 summits on global warming. In 2021, the World Economic Forum proposed leveraging the crisis that the world is experiencing due to COVID-19 for a (...) “great reset” within a globalist agenda that guides the next meeting on climate change. From a bioethical perspective, some components and strategies of this agenda are analyzed, and reflections and recommendations are made. We conclude that climate change is a real issue but magnified by pseudoscience and permeated by politics. Mitigation and adaptation strategies are needed to combat it, including techno-scientific advances, political will, and changes in human behavior. (shrink)

Assisted Reproductive Technologies, as a solution to the issues of human infertility, have been developed since the mid-twentieth century. The development of these techniques, their progress and results have occurred simultaneously with two events related to ART: the establishment of new rights that have contributed to their endorsement, and the birth of bioethics that have allowed the recognition of their limits. The cultural change due to the coming of ART is characterized by three topics that are discussed in this article (...) and which are all included in the so-called gender ideology: the concept of woman and the control of her body, kinship and parentage, and the idea of autonomy. Some considerations on these topics are presented as well as some alternatives to ART, which include learning to redirect their work based on criteria pointed out by bioethical reflection. Such criteria reveal the profound meaning of preserving the dignity of every single person within a true human framework. (shrink)

The analysis is restricted to the architectural aspect. It puts in evidence a dialectical procedure which makes the gnoseological importance of the verb to look stand out clearly. The pharisee's knowledge is based on religious convictions ; that of the blind man on his experience.

This paper compares two logical conditionals which are strengthenings of the strict conditional and avoid the paradoxes of strict implication. The logics of both may be viewed as extensions of KT, and the two conditionals are interdefinable in KT. The implicative conditional requires that its antecedent and consequent be both contingent. The consequential conditional may be viewed as a weakening of the implicative conditional, insofar as it also admits the case in which the antecedent and the consequent are strictly equivalent (...) (either both necessary or both impossible). The two conditionals share a number of properties, among them Transitivity, Contraposition, Aristotle’s Thesis, Weak Boethius’ Thesis and Aristotle’s Second Thesis. They also share some restricted principles such as Possibilistic Monotonicity, Possibilistic Simplification and Possibilistic Right Weakening. They differ in relation to Identity, which is validated by consequential implication, while the implicative conditional only validates the restricted principle of Possibilistic Identity. The relations between the two conditionals are represented by two Aristotelian cubes of opposition, one involving the contrariety between If A, then B and If A, then ¬B, according to Weak Boethius’ Thesis, and the other the contrariety between If A, then B and If ¬A, then B, according to Aristotle’s Second Thesis. We also explore the relations between the two logical conditionals and natural language conditionals, emphasizing the dependence of the latter on the context, and the need to distinguish natural language conditionals which may be viewed as consequential or implicative, on one side, and concessive and some other types of conditionals, on the other. (shrink)

It is argued that contraposition is valid for a class of natural language conditionals, if some modifications are allowed to preserve the meaning of the original conditional. In many cases, implicit temporal indices must be considered, making a change in verb tense necessary. A suitable contrapositive for implicative counterfactual conditionals can also usually be found. In some cases, the addition of certain words is necessary to preserve meaning that is present in the original sentence and would be lost or changed (...) in the contrapositive without them. A distinction is made between adding new meaning and adding new words to preserve existing meaning. For concessive conditionals and relevance conditionals, however, no valid contrapositive can be found. They do not belong to the class of contraposable conditionals, which can be independently defined. Difficult cases are also discussed in which the contradictory of the consequent semantically entails the truth of the antecedent. In such cases the content of the antecedent is implicit in the meaning of the consequent. Contraposition becomes possible if what is implicit in the original consequent is made explicit in the contrapositive antecedent. (shrink)

An examination of conditionals in di¤erent languages leads to a distinction of three types of conditionals instead of the usual two (indicative and subjunctive). The three types can be explained by the degree of acceptance or as-if acceptance of the truth of the antecedent. The labels subjunctive and indicative are shown to be inadequate. So-called indicative conditionals comprise two classes, the very frequent uncertain-fact conditionals and the quite rare accepted-fact conditionals. Uncertain-fact conditionals may have a time shift in contemporary English (...) and the future subjunctive in Portuguese (though not all of them do). Moreover, paraphrases of if with in case or supposing are usually possible with approximately the same meaning. Accepted-fact conditionals never have these features. (shrink)

A commentary is given on Trevena and Miller . The comparability of their experimental task and of the potential they recorded with those used and recorded by Libet, Gleason, Wright, and Pearl is questioned. An interpretation is given for the similarity of event-related potentials recorded when subjects decided to move and when they decided not to move.

In a provocative article published in the Journal of Consciousness Studies, Susan Pockett argues for the plausibility of considering consciousness as an epiphenomenon of neural activity. This means that consciousness, though caused by the brain, would not in its turn have any role in the causation of neural activity and, consequently, of behaviour. Critical for her argument is the distinction she makes between 'consciousness per se' and 'the neural processing that accompanies it' . In her discussion, though, the author begs (...) the question concerning whether there really is such 'consciousness itself, as distinct from the neural processing that goes with it' . If consciousness as it exists happens not to be distinct from some sort of neural processing, then Pockett's 'consciousness per se' has no causal effect simply because it does not exist. (shrink)

Hodgson’s (Journal of Consciousness Studies, 12 (1), 2005) defense of the plain person’s view that free will exists in conscious voluntary action is discussed. His position against the view that human action is automatically determined is favored, but his view that free will is incompatible with natural causation is countered. Eccles’ hypothesis to account for the presence of a readiness potential prior to a conscious decision to act now is discussed. It is argued that it is possible to preserve what (...) is good in a plain person’s concept of free will in a way that is compatible with natural causation. (shrink)

Después de casi medio siglo fue derogada la sentencia del caso Roe vs. Wade por la Corte Suprema de los Estados Unidos, lo que puede suponer el fin del aborto en ese país. Se mencionan algunos antecedentes, hitos históricos, arreglos y el contexto de la situación que desembocó en la sentencia mediante la cual se estableció el derecho constitucional al aborto (Roe vs. Wade), se mantuvo la decisión tomada (Planned Parenthood vs. Casey) y finalmente cómo se revocaron las sentencias anteriores (...) (Dobbs vs. Organización de Salud Femenina Jackson). Se concluye, desde una perspectiva biojurídica, que se corrigió un fallo no solo controvertido en su aplicación, sino sobre todo en su génesis, donde queda claro que el aborto no es un derecho constitucional y que los organismos judiciales no son competentes para regular sobre esa materia y sobre otras análogas. Desde el punto de vista bioético, es un fallo revocatorio histórico, que rectificó una de las mayores injusticias contemporáneas, que puso por encima la autonomía individual sobre el hecho biológico incontrovertible de una nueva vida humana y el cuidado que demanda su dignidad ontológica: Roe vs. Wade costó la vida a millones de embriones, en los Estados Unidos y en el resto del mundo.

Post-pandemic: Triple Agenda for a New RealityPós-pandemia: tripla agenda para uma nova realidadeNew fields for applying bioethics have emerged out of the SARS-Cov-2 pandemic, but many bioethical challenges remain; so, it is necessary to reflect on the reality that human beings will have to live after that. This reflection builds on a triple agenda: challenges, warnings, and guidance. The challenge agenda deals with upcoming scientific and biotechnological developments, adjustments to work and study, sustainable development reorientation, and changes in businesses and (...) entertainment companies. These challenges could be summarized as development paradigm shifts. The warning agenda includes the management of wild species, mistrust in political leaders, unsupportive and criminal human behavior, information overabundance, the emulation of pharmaceutical industries, and the determining factors of the culture of death. These warnings could be condensed in the importance of promoting the culture of life. The guidance agenda comprises a series of principles such as the human person’s dignity, the common good, the preferential option for the poor, the universal allocation of goods, solidarity, subsidiarity, and the care for our common home. This guidance points to a fundamental and existential environmental transformation. All these changes will be possible because of human resilience, professionalism, and social solidarity, shaping an actual comprehensive human development project.Para citar este editorial / To reference this editorial / Para citar este editorialGamboa Bernal GA.

Bergson em As duas fontes da moral e da religião se propõe a investigar a origem da moralidade e da religiosidade humana, encarando-as como formas criadas pelo élan vital no curso do desenvolvimento da vida. Bergson concebe o surgimento da sociedade como algo natural, isto é, como um artifício da natureza para que o homem pudesse perseverar no mundo; assim, sua pesquisa visa encontrar e analisar os caminhos que a vida mesma armou no interior do humano, em sua constituição biológica, (...) para que ele pudesse se apegar de diversas formas à existência. Descortinando os motivos pelos quais as variadas sociedades, bem como suas mais diferentes morais se constituem como fechadas ou visando aos interesses da espécie, e abertas, tendo na humanidade uma referência por onde o amor criativo passaria, o filósofo nos mostra como determinados homens, excepcionais, vêm ao mundo encarnado em múltiplos sentidos uma nova atitude criadora, ainda não expressa, que se revela através de uma intuição despertada por uma emoção profunda. Dessa forma, a relação entre moral, vida e emoção é o que cumpre aqui estabelecer, uma vez que as leis morais seguidas pela humanidade são, no limite, necessidades vitais colocadas pela natureza e que só alcançam um desenvolvimento melhor graças à inteligência humana que, mesmo atrelada à necessidade imposta, também pode encontrar dentro de si a abertura para uma liberdade possível.
