This article pretends to provide a reading of the Seventh Letter focused on the role that medical terminology plays in it. Leaving aside the unsolvable enigma of Plato’s authorship, the letter shows evident connections with fundamental topics from the “last” Plato, particularly in its political aspects. In many passages of the Seventh Letter, the figure of the philosopher as an educator appears covered with medical aspects, and the political situation is defined as a pathology that we must treat according to (...) a therapeutic methodology.

Before Euro-American settlement, many Native American nations intercropped maize (_Zea mays_), beans (_Phaseolus vulgaris_), and squash (_Cucurbita pepo_) in what is colloquially called the “Three Sisters.” Here we review the historic importance and consequences of rejuvenation of Three Sisters intercropping (3SI), outline a framework to engage Native growers in community science with positive feedbacks to university research, and present preliminary findings from ethnography and a randomized, replicated 3SI experiment. We developed mutually beneficial collaborative research agendas with four Midwestern US Native (...) American nations. Ethnographic data highlighted a culturally based respect for 3SI as living beings, the importance it holds for all cultural facets of these Native nations, and the critical impact the practice has on environmental sustainability. One concern expressed by Native growers during ethnographic research was improving soil health—part of the rationale for establishing the 3SI agronomic experiment. To address this, we collaboratively designed a 3SI experiment. After 1 year, 3SI increased short-term soil respiration by 24%, decreased salt-extractable nitrate by 54%, had no effect on soil microbial biomass (but increased its carbon-to-nitrogen ratio by 32%) compared to the average of monoculture crops. The overarching purpose of this collaborative project is to develop a deeper understanding of 3SI, its cultural importance to Native communities, and how reinvigorating the practice—and intercropping in general—can make agroecosystems more sustainable for people and the environment.

El discurso biológico de Ayala se centra en estas tres cuestiones: 1) El hecho de la evolución. 2) Historia de la evolución. 3) Mecanismos del desarrollo y cambio evolutivos. El hecho determinante y cierto, según Ayala, es la evidencia de relaciones entre todos los organismos debidas a una común descendencia con modificaciones como lo han demostrado con abundancia la Paleontología, Anatomía comparada, Biogeografía, Embriología, Genética Molecular, Bioinformática y otras disciplinas biológicas que nos llevan a la afirmación de que el hecho (...) de la evolución de los seres vivos tiene el mismo grado de certeza que poseen los hechos históricos y científicos ampliamente confirmados. Para Ayala, explicaciones acerca del origen del mundo, del hombre y de otras criaturas se encuentran en todas las culturas. Tras la publicación del Origen de las Especies de C. Darwin en 1859, se produce gran polémica en los medios científicos, culturales y religiosos, pero pasado un período de maduración, el darwinismo logra ser aceptado especialmente bajo las formas de Neo-darwinismo y Teoría Sintética. Otro asunto muy distinto son las diversas teorías y micro-teorías que se proponen para explicar los mecanismos de la evolución de los organismos vivos que presentan todavía profundas lagunas, deficiencias y controversias que han provocado la aparición de teorías alternativas. No obstante, el darwinismo moderno constituye un peldaño importante en la reconstrucción del sinuoso y complejo proceso evolutivo de la vida a través de millones de años acudiendo a una razonable explicación causal sin que esto atente contra ningún supuesto religioso.

In this paper we shall examine a few texts by authors who predate Hilary in order to investigate a possible exegetical tradition or interpretative current that could include several gnostic groups cited by Irenaeus of Lyons (II c.), to Origen (III c.) and saint Hilary of Poitiers (IV c.). However, one of the interpretations that Origen presents in his Commentary on saint John is the same interpretation that Hilary gives, but it is more developed. Certainly, Hilary and Origen comment two (...) different Gospels, but both comment homologous scenes; Hilary comments Mt. 8:5-13 and Origen, Io. 4:46-54. In addition, we believe some testimonies in Hilary’s commentary can reveal the influence of Origen’s commentary on Hilary/s. One of these testimonies could be the explanation of the strange reading transmitted by Hilary who calls tribunus to the centurio of the Gospel. (shrink)

Dentro del rico y multiforme panorama de imágenes forjadas en el mundo romano, por su indudable originalidad destacan las iconografías inspiradas en la tierra de los faraones. Concretamente, suscitan interés las representaciones nilóticas animadas por pigmeos provistos de barritas. En el presente trabajo, el objetivo consiste en el identificar, basándose en el estudio de las fuentes clásicas y en las comparaciones iconográficas de las obras examinadas, un fil rouge semántico de estos específicos modelos nilóticos existentes en la cuenca mediterránea (...) entre los siglos I-III d.C. Finalmente, se obtienen ciertas conclusiones acerca de la funcionalidad tanto como del significado de las enigmáticas barritas preservadas hasta nuestros días a través del espejo artístico romano.

Twitter makes conversation into something like a game. It scores our communication, giving us vivid and quantified feedback, via Likes, Retweets, and Follower counts. But this gamification doesn’t just increase our motivation to communicate; it changes the very nature of the activity. Games are more satisfying than ordinary life precisely because game-goals are simpler, cleaner, and easier to apply. Twitter is thrilling precisely because its goals have been artificially clarified and narrowed. When we buy into Twitter’s gamification, then our values (...) shift from the complex and pluralistic values of communication, to the narrower quest for popularity and virality. Twitter’s gamification bears some resemblance with the phenomena of echo chambers and moral outrage porn. In all these phenomena, we are instrumentalizing our ends for hedonistic reasons. We have shifted our aims in an activity, not because the new aims are more valuable, but in exchange for extra pleasure. (shrink)

The objective of this work is to establish a relationship between the cutting time in rocks, determining a speed and the point load strength index test, Is, to characterize the rock in terms of resistance and avoid sending samples to laboratories. As a first stage, on andesite samples, 5 x 5 x 10 cm test tubes were made. After the elaboration they were subjected to cutting, using an electric floor cutter and the time was evaluated. This cut was made in (...) a transversal way and two parts were obtained, one of them with dimensions 5 x 5 x 5 cm, approximately. In a third stage, the point load strength test was carried out in a press built for this purpose. Finally, the cutting speeds were correlated with the point load test values and only when rock samples do not pigeonhole on the proposed relationship, send them to the laboratory. Keywords: Mining fortification, uniaxial compressive strength, rock cutting, point load strength test index. References [1]P. Feijoo, R. Aucay, D.

The notion that our society, its education system and its intellectual life, is characterised by a split between two cultures – the arts or humanities on one hand and the sciences on the other – has a long history. But it was C. P. Snow's Rede lecture of 1959 that brought it to prominence and began a public debate that is still raging in the media today. This fiftieth anniversary printing of The Two Cultures and its successor piece, A Second (...) Look features an introduction by Stefan Collini, charting the history and context of the debate, its implications and its afterlife. The importance of science and technology in policy run largely by non-scientists, the future for education and research, and the problem of fragmentation threatening hopes for a common culture are just some of the subjects discussed.

C. Stephen Evans explains and defends Kierkegaard's account of moral obligations as rooted in God's commands, the fundamental command being `You shall love your neighbour as yourself'. The work will be of interest not only to those interested in Kierkegaard, but also to those interested in the relation between ethics and religion, especially questions about whether morality can or must have a religious foundation. As well as providing a comprehensive reading of Kierkegaard as an ethical thinker, Evans puts him into (...) conversation with contemporary moral theorists. Kierkegaard's divine command theory is shown to be an account that safeguards human flourishing, as well as protecting the proper relations between religion and state in a pluralistic society.

One of the very few accounts in English of German idealism, this ambitious work advances and revises our understanding of both the history and the thought of the classical period of German philosophy. As he traces the structure and evolution of idealism as a doctrine, Frederick Beiser exposes a strong objective, or realist, strain running from Kant to Hegel and identifies the crucial role of the early romantics—Hölderlin, Schlegel, and Novalis—as the founders of absolute idealism.

Is there such a thing as natural knowledge of God? C. Stephen Evans presents the case for understanding theistic arguments as expressions of natural signs in order to gain a new perspective both on their strengths and weaknesses. Three classical, much-discussed theistic arguments - cosmological, teleological, and moral - are examined for the natural signs they embody. At the heart of this book lie several relatively simple ideas. One is that if there is a God of the kind accepted by (...) Christians, Jews, and Muslims, then it is likely that a 'natural' knowledge of God is possible. Another is that this knowledge will have two characteristics: it will be both widely available to humans and yet easy to resist. If these principles are right, a new perspective on many of the classical arguments for God's existence becomes possible. We understand why these arguments have for many people a continued appeal but also why they do not constitute conclusive 'proofs' that settle the debate once and for all. Touching on the interplay between these ideas and contemporary scientific theories about the origins of religious belief, particularly the role of natural selection in predisposing humans to form beliefs in God or gods, Evans concludes that these scientific accounts of religious belief are fully consistent, even supportive, of the truth of religious convictions.

The fact that many modal operators are part of an adjunction is probably folklore since the discovery of adjunctions. On the other hand, the natural idea of a minimal propositional calculus extended with a pair of adjoint operators seems to have been formulated only very recently. This recent research, mainly motivated by applications in computer science, concentrates on technical issues related to the calculi and not on the significance of adjunctions in modal logic. It then seems a worthy enterprise (both (...) for these contemporary topical pursuits and also for historical interest) to trace the concept of adjunction back to the origins of the algebraic semantics of modal logic and to make explicit its ubiquity in this branch of mathematics.

C. S. Lewis sets out to persuade his audience of the importance and relevance of universal values such as courage and honor in contemporary society.

Michel Foucault had a great influence upon a wide range of disciplines, and his work has been widely interpreted and is frequently referred to, but it is often difficult for beginners to find their way into the complexities of his thought. This is especially true for readers whose background is Anglo-American or "analytic" philosophy. C. G. Prado argues in this updated introduction that the time is overdue for Anglo-American philosophers to avail themselves of what Foucault offers. In this clear and (...) greatly-revised second edition, Prado focuses on Foucault's "middle" or genealogical work, particularly Discipline and Punish and Volume One of The History of Sexuality, in which Foucault most clearly comes to grips with the historicization of truth and knowledge and the formation of subjectivity. Understanding Foucault's thought on these difficult subjects requires working through much complexity and ambiguity, and Prado's direct and accessible introduction is the ideal place to start.

Plato. Aristotle. Augustine. Hume. Kant. Hegel. Every student of philosophy needs to know the history of the philosophical discourse such giants have bequeathed us. Philosopher C. Stephen Evans brings his expertise to this daunting task as he surveys the history of Western philosophy, from the Pre-Socratics to Nietzsche and postmodernism—and every major figure and movement in between.

Emerald Fennell’s debut feature Promising Young Woman (2020) incisively examines sexual assault, misogyny, and the culture of complicity that continues to perpetuate `violence against women. This article will establish Fennell’s aptitude as a filmmaker in condemning the pervasive forces of patriarchal social order in harmony with Kate Manne’s account of structural misogyny analyzed in Down Girl (2017) and Entitled (2020). Fennell’s subversion of genre standards demonstrates how the actions of individuals, separate from the perpetrator, lead to additional acts of harm, (...) and addresses the ever-present reality of male violence which the feminist-hero is, ultimately, unable to surmount. Despite arguments that Promising Young Woman has not met the expectations for change the me-too movement inspired, Fennell challenges conventions to expose misogyny and male violence asking that future feminist filmgoers consider a new way forward.

This book reveals the rational basis for historians' descriptions, interpretations and explanations of past events. C. Behan McCullagh defends the practice of history as more reliable than has recently been acknowledged. Historians, he argues, make their accounts of the past as fair as they can and avoid misleading their readers. He explains and discusses postmodern criticisms of history, providing students and teachers of history with a renewed validation of their practice. McCullagh takes the history debate to a new stage with (...) bold replies to the major questions historians face today. (shrink)

Conscious macrostates are usually assumed to be emergent from the underlying physical microstates comprising the brain and nervous system of biological organisms. However, a major problem with this assumption is that consciousness is essentially nonmeasurable unlike all other proven emergent properties of physical systems. In an earlier paper, using a no-go theorem, it was shown that conscious states cannot be comprised of processes that are physical in nature (Reason, 2019). Combining this result with another unrelated work on causal emergence in (...) physical systems (Hoel, Albantakis and Tononi, 2013), we show in this paper that conscious macrostates are not emergent from physical systems and they also do not supervene on physical microstates. An important implication of our work is that there must be some form of violation of energy conservation in biological systems that are conscious. (shrink)

Are the relations between the property of a thing and its related disposition to react in certain ways, and between the triggering of that disposition and the consequent effect, necessary? Harré and Madden, in their analysis of causal powers, said they are, but their arguments are not persuasive. Humeans like Simon Blackburn deny it. I criticize the Humean position, and argue afresh for their necessity. I note that David Lewis' analysis of causation requires their necessity, though as a confessed Humean (...) he has not admitted this. (shrink)
