The removal of water from mines was one of the key issues that former miners had to deal with. Roman colonists brought new technology to the Iberian Peninsula that addressed this problem. However, they did not invent this technology because it had already been applied to the growth of other endeavours in the Hellenistic society throughout the Eastern Mediterranean. In the mine, the Archimedes screw, waterwheels, bucket pulleys, and Ctesibius pumps were the primary drainage systems. In this essay, the primary (...) characteristics, and modes of operation of machines are examined. Without leaving out the most significant finds made in the southwest of the Iberian Peninsula, one of the regions with the longest history of mining exploitation. To serve as a foundation for future research in this field, this work compares the primary mining mechanisms in ancient Huelva on a qualitative and quantitative level by the implementation of a TOPSIS methodology, a multi-criteria decision analysis method.

Friedrich Nietzsche (1844-1900) has had a profound impact on our way of life. Among other things, he was a philosopher, a poet, and a scholar. Unfortunately, he suffered from poor health, which caused him to resign from his position as the Chair of Classical Philology, which he held at the age of 24. At 44, he was so ill that his mother, and then his sister had to care for him until his death at the page of 55. Nietzsche wrote (...) on numerous subjects, but is commonly associated with nihilism, critiques of Christian morality, and his strong opposition to anti-Semitism and nationalism. There was a brief time when his sister reworked his manuscripts to favor Nazi ideology, but the correct manuscripts were uncovered. Many scholars have written about Nietzsche. J. M. Kennedy was the pen name for John McFarland, who wrote extensively on Nietzsche. He also wrote on education, philology and war. This new edition is dedicated to Daniel Gutierrez Sandoval and Emma Norman, who have had different views of Nietzsche. Please note that this is a reprint of the original version, and has a few small blemishes. (shrink)

The tree-based data structure of -tree for propositional formulas is introduced in an improved and optimised form. The -trees allow a compact representation for negation normal forms as well as for a number of reduction strategies in order to consider only those occurrences of literals which are relevant for the satisfiability of the input formula. These reduction strategies are divided into two subsets (meaning- and satisfiability-preserving transformations) and can be used to decrease the size of a negation normal form A (...) at (at most) quadratic cost. The reduction strategies are aimed at decreasing the number of required branchings and, therefore, these strategies allow to limit the size of the search space for the SAT problem. (shrink)

Se presentan en este artículo los resultados que surgieron de incorporar lecciones de Autoconciencia por el Movimiento (ATM) -como estrategia pedagógica- para reconocer y actuar en pro de nuestro ambiente interno y externo, realizado con un grupo interprofesional de mujeres. El grupo se forma e investiga a sí mismo, bajo el enfoque de la Investigación Acción Participativa, y busca comprender mejor los procesos de formación ambiental en los campos de la salud y el ambiente.

The Constitution of the Athenians ascribed to Xenophon the orator.--The Politeia of the Spartans by Xenophon.--The Boeotian Constitution from the Oxyrhynchus historian.--The Constitution of Athens by Aristotle.

In this 1974 book a practising scientist and gifted expositor sets forth an exciting point of view on the nature of science and how it works.

BLWith new text and full apparatus criticus The Eudemian Ethics was one of two ethical treatises which Aristotle wrote on the subject of ethica or `matters to do with character'. Although the two works cover much the same ground, the Nicomachean Ethics is better known; the poor manuscript tradition of the Eudemian Ethics has made correct translation and interpretation of the text extremely difficult. The subject of the work is the choice of a certain means of conduct, made by a (...) `man of practical wisdom', between two extremes of behaviour: asceticism and yielding to uncontrolled impulses. Aristotle also stresses the notion of moral intention and the importance of virtue of character. This new Oxford Classical Text of the Eudemian Ethics is the result of many years of work. After Sir David Ross's death, his original text was substantially reworked and revised by his friend and colleague R. R. Walzer, who was aided in the revision by his former pupil Mrs Jean Mingay, who continued his work after his death in 1974. Mrs Mingay was fortunate in being able to make use of previously unpublished contributions from D. J. Allan after his death in the late seventies, and more recently has been helped in her work by the suggestions of Professor D. A. Russell, David Robinson, and Christopher Rowe. (shrink)

Theodor W. Adorno is best known for his contributions to aesthetics and social theory. Critics have always complained about the lack of a practical, political or ethical dimension to Adorno's philosophy. In this highly original contribution to the literature on Adorno, J. M. Bernstein offers the first attempt in any language to provide an account of the ethical theory latent in Adorno's writings. Bernstein relates Adorno's ethics to major trends in contemporary moral philosophy. He analyses the full range of Adorno's (...) major works, with a special focus on Dialectic of Enlightenment, Minima Moralia and Negative Dialectics. In developing his account Bernstein lays particular stress on Adorno's contention that the event of Auschwitz demands a new categorical imperative. This book will be widely acknowledged as the standard work on Adorno's ethics and as such will interest professionals and students of philosophy, political theory, sociology, history of ideas, art history and music.

SummaryIt is shown that the concept of understanding cannot be reduced to a combination of knowing that, knowing how, and knowledge by acquaintence. First, it is shown that understanding and knowledge have different objects. Then “understanding what” is analyzed along Aristotelian lines. In the central part of the paper it is shown that understanding objects defined by constitutive rules involves a non‐propositional component. This notion of “understanding” is shown to cut across the humanist‐scientist dichotomy.

In this unflinching look at the experience of suffering and one of its greatest manifestations—torture—J.M. Bernstein critiques the repressions of traditional moral theory, showing that our morals are not immutable ideals but fragile constructions that depend on our experience of suffering itself. Morals, Bernstein argues, not only guide our conduct but also express the depth of mutual dependence that we share as vulnerable and injurable individuals. Beginning with the attempts to abolish torture in the eighteenth century, and then sensitively examining (...) what is suffered in torture and related transgressions, such as rape, Bernstein elaborates a powerful new conception of moral injury. Crucially, he shows, moral injury always involves an injury to the status of an individual as a person—it is a violent assault against his or her dignity. Elaborating on this critical element of moral injury, he demonstrates that the mutual recognitions of trust form the invisible substance of our moral lives, that dignity is a fragile social possession, and that the perspective of ourselves as potential victims is an ineliminable feature of everyday moral experience.
