I examine Alexander of Aphrodisias’ theory of action, addressing the question how his view that human actions are determined by reason accounts for the capacity of doing otherwise. Calling into question the standard view that Alexander frees agents from internal determination, I argue that (1) the capacity of doing otherwise is a consequence of determination by reason, since it enables agents to do something different from what they would have done had they followed external circumstances; and (2) this capacity is (...) compatible with causal determination by reason because as a case of potentiality for opposites, it grants agents the qualified possibility of doing otherwise insofar as their nature as human beings is concerned – a possibility which remains also when their actions are causally determined by reason and by their internal disposition. I show further that these elements of Alexander’s theory of action are ultimately based on his conception of the soul, specifically on his commitment to Aristotle’s view that the human soul is not purely rational, as the Stoics hold, but has nonrational and rational parts.

I examine the question why in Proclus' view genetic processes provide demonstrative explanations, in light of the interpretation of Aristotle's theory of demonstration in late antiquity. I show that in this interpretation mathematics is not an explanatory science in the strict sense because its objects, being immaterial, do not admit causal explanation. Placing Proclus' account of demonstrative explanation in this context, I argue that this account is aimed at answering the question whether mathematical proofs provide causal explanation as opposed to (...) grounds. I show further that Proclus can answer this question in the affirmative due to his realist view of mathematical objects and the priority he ascribes to causal relations over logical relations.

This paper examines the widely accepted contention that geometrical constructions serve in Greek mathematics as proofs of the existence of the constructed figures. In particular, I consider the following two questions: first, whether the evidence taken from Aristotle's philosophy does support the modern existential interpretation of geometrical constructions; and second, whether Euclid's Elements presupposes Aristotle's concept of being. With regard to the first question, I argue that Aristotle's ontology cannot serve as evidence to support the existential interpretation, since Aristotle's ontological (...) discussions address the question of the relation between the whole and its parts, while the modern discussions of mathematical existence consider the question of the validity of a concept. In considering the second question, I analyze two syllogistic reformulations of Euclidean proofs. This analysis leads to two conclusions: first, it discloses the discrepancy between Aristotle's view of mathematical objects and Euclid's practice, whereby it will cast doubt on the historical and theoretical adequacy of the existential interpretation. Second, it sets the conceptual background for an alternative interpretation of geometrical constructions. I argue, on the basis of this analysis that geometrical constructions do not serve in the Elements as a means of ascertaining the existence of geometrical objects, but rather as a means of exhibiting spatial relations between geometrical figures.

In this article I explain three puzzling features of Simplicius’ use of syllogistic reconstructions in his commentary on Aristotle’s Physics: (1) Why does he reconstruct Aristotle’s non-argumentative remarks? (2) Why does he identify the syllogistic figure of an argument but does not explicitly present its reconstruction? (3) Why in certain lemmata does he present several reconstructions of the same argument? Addressing these questions, I argue that these puzzling features are an expression of Simplicius’ assumption that formal reasoning underlies Aristotle’s prose, (...) hence they reflect his attempt to capture as faithfully as possible Aristotle’s actual mode of reasoning. I show further that, as a consequence of this seemingly descriptive use of syllogistic reconstructions, logic serves Simplicius not only as an expository and clarificatory tool of certain interpretations or philosophical views, but also motivates and shapes his exegetical stances and approach.

As soon as Rabbi Shneur Zalman of Liadi (the Baal HaTanya) formulated his method of self-mastery, more than two hundred years ago, it spread like wildfire. Within a few years, thousands had knocked on his door to get "therapy" with individually tailored advice for various emotional challenges. The Tanya was compiled over a twenty-year period to present a comprehensive framework that would serve as a substitute for a face-to-face encounter and last for generations to come. Rabbi Shneur Zalman's method sees (...) a person as locked in a lifelong internal struggle. The mission of life is to win the struggle in the present moment. This optimistic attitude toward the human psyche - and the claim that at any moment one can be victorious in the day's struggles - has captivated hearts for centuries and is here available to the modern reader in a down-to- earth presentation. Winning Every Moment enables the reader to develop an intimate spiritual conversation with the great master of Jewish psychology. Through this soul conversation with the Baal HaTanya, you are invited to know yourself and your inner powers. (shrink)

I argue that Aristotle’s late-antique commentators read into his theory of demonstration the notion of tekmeriodic proofs in attempt to integrate into the theory of demonstration the assumption that the principles of demonstration should be evident. In so doing, I trace the late antique commentators’ view to Alexander of Aphrodisias’ discussion of the principles of demonstration, showing how his assumption that the principles of demonstration should be evident underlies their notions of tekmeriodic proofs.

Many patients believe that cardiopulmonary resuscitation (CPR) is more likely to be successful than it really is in clinical practice. Even when working with accurate information, some nevertheless remain resolute in demanding maximal treatment. They maintain that even if survival after cardiac arrest with CPR is extremely low, the fact remains that it is still greater than the probability of survival after cardiac arrestwithoutCPR (ie, zero). Without realising it, this line of reasoning is strikingly similar to Pascal’s Wager, a Renaissance-era (...) argument for accepting the proposition for God’s existence. But while the original argument is quite logical—if not universally compelling—the modern variant makes several erroneous assumptions. The authors here present a case of a patient who unwittingly appeals to Pascal’s Wager to explain his request for maximal treatment, in order to highlight the crucial divergences from the original Wager. In understanding the faulty assumptions inherent in the application of Pascal’s Wager to code status decisions—and identifying the underlying motivations which the Wager serves to confirm—providers can better ensure that the true values and preferences of patients are upheld.

Clinical simulation using standardized patients has become standard in medical education—and is now being incorporated into some graduate programs in bioethics—for both formative and summative evaluation. In most hospitals, though, clinical ethics consultation is done by the ethics committee (or a subset of it). This study is the first, to our knowledge, to examine the effectiveness of standardized patient simulation in training hospital ethics committees to deal with ethically complex and emotionally fraught clinical situations. Following a substantial revision of the (...) institution’s nonbeneficial treatment policy, ethics committee members underwent a simulation to determine whether a specific requested treatment should be withheld on the basis of futility. Pre- and postintervention surveys showed improvement in all domains, although the small sample size limited the power of the study, with only one measure showing a statistically significant difference. An interesting incidental finding was that one-quarter of committee members voted against a determination of futility, even though the case clearly met the definition set forth in the policy. This highlights the emotional challenges in implementing an ethically rigorous, unanimously accepted policy that ultimately determines the timing and manner of a patient’s death. (shrink)

The article argues that youth’s exposure to thin-idealizing content posted by their adored celebrities on interactive and highly engaging social networking sites poses potential challenges for these young people. Celebrity SNS presence responds to youth’s desire for social connectedness, public approval, and fame, which are highlighted at the time of their identity search and establishment. SNS content likely interacts with teens’ unique developmental characteristics, personal background, and interests to propel processes such as identification and social comparison with famous personae leading (...) to negative body image perceptions. The article suggests that even ostensibly “innocent” SNS content that presents thin-idealizing images and messages about the body may place pressures on youth and encourage a preoocupation with and risky behaviors associated with body image even unintentionally. The article further recognizes that netusers, readers, and social networking sites all share in the responsibility to minimize the risks posed to youth in this context. (shrink)

Here, an epidemiological model considering pro and anti-vaccination groups is proposed and analyzed. In this model, susceptible individuals can migrate between these two groups due to the influence of false and true news about safety and efficacy of vaccines. From this model, written as a set of three ordinary differential equations, analytical expressions for the disease-free steady state, the endemic steady state, and the basic reproduction number are derived. It is analytically shown that low vaccination rate and no influx to (...) the pro-vaccination group have similar impacts on the long-term amount of infected individuals. Numerical simulations are performed with parameter values of the COVID-19 pandemic to illustrate the analytical results. The possible relevance of this work is discussed from a public health perspective. (shrink)

How children seek knowledge and evaluate claims may depend on their understanding of the source of knowledge. What shifts in their understandings about why scientists might disagree and how claims about the state of the world are justified? Until about the age of 41/2, knowledge is seen as self-evident. Children believe that knowledge of reality comes directly through our senses and what others tell us. They appeal to these external sources in order to know. The attainment of Theory of Mind (...) (ToM) at this age is commonly seen as the significant shift in development in understanding disagreements in knowledge claims. Children attaining ToM understand that someone exposed to incorrect or incomplete information might have false beliefs. Disagreement, then, is still attributed to objective sources of knowledge. The current study examines the later developing Interpretive Theory of Mind (iToM) as the basis for children’s understanding of how people with access to the same information might disagree and what this means for how to provide justification for a knowledge claim. Fourteen 2nd graders with the most iToM responses to four tasks and 14 with the fewest iToM responses were selected from a larger sample of 91. In analyses of interviews about a story in which two experts make different claims about a scientific phenomenon, those in the high iToM group noted subjective perspective and processes as the source of disagreement and suggested the need for investigation as the means to knowing. In contrast, those in the low iToM group mostly could not explain the source of disagreement and held that knowledge is acquired from external sources. A comparison of the interviews regarding the science story 2 years later allows for a qualitative description of the development. Those in the low iToM group showed more general recognition of subjective and constructive processes in knowing whereas those in the high iToM group identified interpretive processes and the relativity of perspectives with implications for how observations were conducted and interpreted. Only those in the high iToM group referred to the importance of evidence as a basis for knowledge claims at either point in the study. (shrink)

In his _Sapiens: A Brief History of Humankind_, Yuval Harari claims that humans are able to cooperate in large numbers because they share common beliefs in fictions or “things that do not exist at all”. Examples of these fictions are religious doctrines, nations, laws, justice and money. In my paper, I argue that Harari is right to point out the importance of social constructs, entities that depend for their existence on the beliefs of the members of a society, (...) for cooperation. But he is wrong to characterise social constructs as fictions or imagined realities. Doing so makes it difficult to distinguish between real social constructs and social constructs that are fictitious or merely imagined. Harari tries to remedy this problem calling fictitious social constructs lies; but this suggestion unhelpfully associates mere fictions or imaginings with deceptive intent. (shrink)

Yuval Noah Harari contends that human rights are an outdated myth. He calls for replacing them with a new global ethic to meet crises as varied as environmental destruction, disruptive technologies, and extreme gaps between rich and poor. Toward that end, he outlines an ethics that exalts compassion and elides justice, an ethics that animates his trilogy: Sapiens, Homo Deus, and 21 Lessons for the 21st Century. I draw together the key elements in his personal ethics, tracing them to (...) a combination of scientism, postmodernism, and Buddhism. I then argue that he misunderstands human rights, inflates the role of science in moral matters, and fails to reconcile his moral passion with his moral skepticism. (shrink)

The foundational principles of representative democracy are under attack globally. What we desperately need are enlightened and persuasive public intellectuals who can help us see through the fog of our fear, anger, and disillusionment, to find our rational political commitments again. One of these public intellectuals is undoubtedly Yuval Noah Harari, the bestselling author of three recent books – Sapiens, Homo Deus, and 21 Lessons for the 21st Century. Harari is also a frequent contributor in the popular press, (...) and a guest on shows, podcasts, panels, and as a keynote speaker. Add to all this that Harari is acting on his lofty academic ideals through ‘Sapienship’, a multidisciplinary organization he cofounded that advocates for global responsibility, clarifies the global conversation, and focuses attention on the most important global challenges. I single out Harari because I presume many readers will be familiar with his work. He is certainly one of the fastest rising stars of public intellectualism. Unfortunately, his work is undercut by the philosophical positions he put forth in his first bestselling book, Sapiens. In this review/critique I wish to show that in order for Harari advance a coherent political or ideological argument, he must first shore up his philosophical commitments. (shrink)

Althusser’s reception within Argentinian psychoanalytic culture assumed a variety of different forms. For the purposes of delimiting mediations between Marxism, structuralism and psychoanalysis in Argentina during the 1960s and ’70s, this work seeks to reconstruct historical readings of Althusser according to his reception within three distinct interpretative communities. The first group, centring on the figure of Oscar Masotta, concerns Althusser’s role in the development of Argentina’s incipient Lacanian groups. For the second group, primarily dissident-psychoanalytic and Freudo-Marxist, the reception of Althusser (...) will be considered in tandem with ensuing debates between Freudo-Marxism and Althussero-Lacanism. The third group asks us to consider the role of Althusserianism in discussions around the professionalisation of psychology, where the careers of Carlos Sastre and Roberto Harari showed the strongest connections to Althusser’s work.

A paradigm-shifting work that revolutionizes our understanding of the origins and structure of science. Captivatingly written, interwoven with tantalizing illustrations and historical vignettes ranging from Newton's alchemy to quantum mechanics to the storm surge of Hurricane Sandy, Michael Strevens's wholly original investigation of science asks two fundamental questions: Why is science so powerful? And why did it take so long, two thousand years after the invention of philosophy and mathematics, for the human race to start using science to learn the (...) secrets of nature? The Knowledge Machine's radical answer is that science calls on its practitioners to do something irrational: by willfully ignoring religion, theoretical beauty, and, especially, philosophy-essentially stripping away all previous knowledge-scientists embrace an unnaturally narrow method of inquiry, channeling unprecedented energy into observation and experimentation. Like Yuval Harari's Sapiens or Thomas Kuhn's 1962 classic, The Structure of Scientific Revolutions, The Knowledge Machine overturns much of what we thought we knew about the origins of the modern world.

For millennia, war was viewed as a supreme test. In the period 1750-1850 war became much more than a test: it became a secular revelation. This new understanding of war as revelation completely transformed Western war culture, revolutionizing politics, the personal experience of war, the status of common soldiers, and the tenets of military theory.

In Homo Deus, Yuval Noah Harari argues that technological advances of the twenty-first century will usher in a significant shift in how humans make important life decisions. Instead of turning to the Bible or the Quran, to the heart or to our therapists, parents, and mentors, people will turn to Big Data recommendation algorithms to make these choices for them. Much as we rely on Spotify to recommend music to us, we will soon rely on algorithms to decide our (...) careers, spouses, and commitments. Harari also predicts that next, the state will take away individuals’ rights to make their own choices about their lives. If Google knows where your children would flourish best in school, why should the state allow a fallible human parent to decide? Liberalism—which, as Harari uses this term, refers to a state of society in which human freedom to choose is respected and championed—will collapse. In this paper, I argue that Harari’s conception of the future implications of recommendation algorithms is deeply flawed, for two reasons. First, users will not rely on algorithms to make decisions for them because they have no reason to trust algorithms, which are developed by companies with their own incentives, such as profit. Second, for most of our life decisions, algorithms will not be able to be developed, because the factors relevant to the decisions we face are unique to our situation. I present an alternative depiction of the future: instead of relying on algorithms to make decisions for us, humans will use algorithms to enhance our decision-making by helping us consider the most relevant choices first and notice information we might not otherwise. Finally, I will also argue that even if computers could make many of our decisions for us, liberalism as a political system would emerge unscathed. (shrink)

Many scholars make a very clear distinction between intelligence and consciousness. Let’s take one of the most famous today, Israeli history Professor, Yuval Noah Harari, the author of Sapiens and Homo Deus. In his 2018 book, 21 lessons for the twenty-first century, he writes that, “intelligence and consciousness are very different things. Intelligence is the ability to solve problems. Consciousness is the ability to feel things such as pain, joy, love, and anger.”.

With the development of science, a lot of people don’t believe in the afterlife, but believe in biotechnology and the ability to overcome death, or at least delay it as much as possible. At the same time, the revolution in medical technology has created the illusion of controlling death. In this study we will consider the impact of scientific progress on changing transhumanity’s vision of death. The aim of the article is a socio-philosophical review of the dynamics and changes in (...) transhumanist ideas about obtaining human immortality from the ideas of cryonics to cybernetic modification of human nature. Research methods are comprehensive and based on philosophical-anthropological and philosophical-cultural analysis of transhumanist concepts of human immortality.Discussion. Comparing the arguments of transhumanists about overcoming death by various methods, it becomes clear that the possibility of obtaining immortality through cryonics technologies is no longer the subject of discussion by scientists and philosophers. The attention of philosophers N. Badmington, N. Bostrom, J.Wilsdon, YN Harari, A. Turchin and M. Bakhtin is focused on the possibility of modifying the human body into an eternal cyborg personality. Conclusion. Human modification for the sake of immortality or its cyborgization is the dominant idea of solving the problem of human mortality. The expansion of the boundaries of human nature and the same time of human existence is first of all a transition to a new qualitative level of existence. As a result it is the opportunity to transfer human thoughts, memories and consciousness into the digital form or to an artificial device. So transhumanists will be able to take refuge in digital immortality. And this immortality will depend only on the ability to build and store these devices. (shrink)

Automation, artificial intelligence, and biotechnology have become topics of increasing interest in both academia as well as in popular media. The goal of this article is to establish which issues are the most pressing, and what are the underlying causes of the rise of robots. I demonstrate that fears of automation are well supported by current trends of automation as well as the inherent tendency within a capitalist system to automate at the expense of workers and working wages. Additionally, I (...) point to what appears to be a potential evolutionary divide between what Yuval Noah Harari calls the “god” class and the “useless” class. Finally, I discuss how the new role of information as the world’s most valued commodity can either exacerbate this coming divide or liberate society. I present the case that in order to diminish the negative effects we must move beyond the present capitalist economic system, towards one in which economic democracy and the free flow of information thrives.

In recent decades, more and more works have appeared, the authors of which are trying to predict possible scenarios for the future development of mankind. This article discusses 5 such scenarios: F. Fukuyama believes that all peoples and countries of the globe in the XXI century will develop in the direction of building a liberal-democratic society; Representatives of the Club of Rome in their latest report, based on statistical data of industrial development, substantiate the idea that by the middle of (...) the XXI century. the Earth’s biosphere will become unsuitable for human life and humanity will begin to die out; representatives of the transhumanist movement in their “Manifesto” set themselves the goal of replacing the human biological body with an artificial body by 1245 and thereby saving people from diseases, from old age and even from death itself; English economist D. Susskind in his book “The Future Without Jobs” predicts that in the next two to three decades, robots and artificial intelligence will force people out of all areas of production and discusses the question of how people who are deprived of the opportunity to work will live; Finally, the Israeli historian Yu.N. Harari in his extensive work “Homo Deus” paints a picture of the fact that scientific and technological progress will turn “reasonable man” into “divine man” in the near future. Assessing all these scenarios for the future development of mankind, one involuntarily comes to the conclusion that they all speak of the death of mankind in the near future. (shrink)

Este trabajo evalúa y analiza la experiencia del aburrimiento en la sociedad contemporánea. Toma como punto de partida las consideraciones schopenhauerianas sobre la voluntad, el ciclo del sufrimiento y el aburrimiento. Posteriormente, observa de qué manera lo anterior está anclado, en la actualidad, a las formas espaciales y temporales que se despliegan con el establecimiento del capitalismo. Se argumenta que el aburrimiento, en esta configuración específica, tiene un carácter dual: el capitalismo es un excelente pasatiempo, pero también tiene un componente (...) de aburrilidad, que hace que estemos permanentemente sumergidas en un ciclo similar —y a la vez distinto en muchas formas— del que había propuesto Schopenhauer. Se propone un ejercicio hermenéutico de varios pasajes de El Mundo como voluntad y representación, y a la vez se articula un intento fenomenológico de “ir a la experiencia misma del aburrimiento”. Finalmente, la conclusión incluye una breve reflexión sobre el aburrimiento durante el COVID- 19. (shrink)
