We explore the distinctive characteristics of Mexico's society, politics and history that impacted the establishment of genetics in Mexico, as a new disciplinary field that began in the early 20th century and was consolidated and institutionalized in the second half. We identify about three stages in the institutionalization of genetics in Mexico. The first stage can be characterized by Edmundo Taboada, who was the leader of a research program initiated during the Cárdenas government (1934-1940), which was primarily directed towards improving (...) the condition of small Mexican farmers. Taboada is the first Mexican post-graduate investigator in phytotechnology and phytopathology, trained at Cornell University and the University of Minnesota, in 1932 and 1933, respectively. He was the first investigator to teach plant genetics at the National School of Agriculture and wrote the first textbook of general genetics, Genetics Notes, in 1938. Taboada's most important single genetics contribution was the production of "stabilized" corn varieties. The extensive exile of Spanish intellectuals to Mexico, after the end of Spain's Civil War (1936-1939), had a major influence in Mexican science and characterizes the second stage. The three main personalities contributing to Mexican genetics are Federico Bonet de Marco and Bibiano Fernández Osorio Tafall, at the National School of Biological Sciences, and José Luis de la Loma y Oteyza, at the Chapingo Agriculture School. The main contribution of the Spanish exiles to the introduction of genetics in Mexico concerned teaching. They introduced in several universities genetics as a distinctive discipline within the biology curriculum and wrote genetics text books and manuals. The third stage is identified with Alfonso León de Garay, who founded the Genetics and Radiobiology Program in 1960 within the National Commission of Nuclear Energy, which had been founded in 1956. The Genetics and Radiobiology Program rapidly became a disciplinary program, for it embraced research, teaching, and training of academics and technicians. The Mexican Genetics Society, created by de Garay in 1966, and the development of strains and cultures for genetics research were important activities. One of de Garay's key requirements was the compulsory training of the Program's scientists for at least one or two years in the best universities of the United States and Europe. De Garay's role in the development of Mexican genetics was fundamental. His broad vision encompassed the practice of genetics in all its manifestations. (shrink)

The ultimate source of explanation in biology is the principle of natural selection. Natural selection means differential reproduction of genes and gene combinations. It is a mechanistic process which accounts for the existence in living organisms of end-directed structures and processes. It is argued that teleological explanations in biology are not only acceptable but indeed indispensable. There are at least three categories of biological phenomena where teleological explanations are appropriate.
The question whether ethical behavior is biologically determined may refer either to thecapacity for ethics (e.i., the proclivity to judge human actions as either right or wrong), or to the moralnorms accepted by human beings for guiding their actions. My theses are: (1) that the capacity for ethics is a necessary attribute of human nature; and (2) that moral norms are products of cultural evolution, not of biological evolution.Humans exhibits ethical behavior by nature because their biological makeup determines the presence (...) of the three necessary, and jointly sufficient, conditions for ethical behavior: (i) the ability to anticipate the consequences of one's own actions; (ii) the ability to make value judgements; and (iii) the ability to choose between alternative courses of action. Ethical behavior came about in evolution not because it is adaptive in itself, but as a necessary consequece of man's eminent intellectual abilities, which are an attribute directly promoted by natural selection.

The question whether ethical behavior is biologically determined may refer either to the capacity for ethics (i.e., the proclivity to judge human actions as either right or wrong), or to the moral norms accepted by human beings for guiding their actions. I herein propose: (1) that the capacity for ethics is a necessary attribute of human nature; and (2) that moral norms are products of cultural evolution, not of biological evolution. Humans exhibit ethical behavior by nature because their biological makeup (...) determines the presence of three necessary conditions for ethical behavior: (i) the ability to anticipate the consequences of one’s own actions; (ii) the ability to make value judgments; and (iii) the ability to choose between alternative courses of action. Ethical behavior came about in evolution not because it is adaptive in itself, but as a necessary consequence of man’s eminent intellectual abilities, which are an attribute directly promoted by natural selection. That is, morally evolved as an exaptation, not as an adaptation. Since Darwin’s time there have been evolutionists proposing that the norms of morality are derived from biological evolution. Sociobiologists represent the most recent and most subtle version of that proposal. The sociobiologists' argument is that human ethical norms are sociocultural correlates of behaviors fostered by biological evolution. I argue that such proposals are misguided and do not escape the naturalistic fallacy. The isomorphism between the behaviors promoted by natural selection and those sanctioned by moral norms exist only with respect to the consequences of the behaviors; the underlying causations are completely disparate.

Stephen Jay Gould’s monumental The Structure of Evolutionary Theory ‘‘attempts to expand and alter the premises of Darwinism, in order to build an enlarged and distinctive evolutionary theory . . . while remaining within the tradition, and under the logic, of Darwinian argument.’’ The three branches or ‘‘fundamental principles of Darwinian logic’’ are, according to Gould: agency (natural selection acting on individual organisms), efficacy (producing new species adapted to their environments), and scope (accumulation of changes that through geological time yield (...) the living world’s panoply of diversity and morphological complexity). Gould’s efforts to contribute something important to each of these three fundamental components of Darwinian Theory are far from successful. (shrink)
The theory of punctuated equilibrium has been proposed as a challenge to the modern synthesis of evolutionary theory. Two important issues are raised. The first is scientific: whether morphological change as observed in the paleontological record is essentially always associated with speciation events. This paper argues that there is at present no empirical support for this claim: the alleged evidence is based on a definitional fallacy. The second issue is epistemological: whether macroevolution is an autonomous field of study, independent from (...) microevolutionary knowledge. It is herein argued that macroevolution and microevolution are not decoupled in two senses: identity at the level of events and compatibility of theories. But macroevolution is autonomous in the epistemologically important sense: macroevolutionary theories are not reducible to microevolutionary principles. It is finally pointed out that the discipline of macroevolution is notoriously lacking in theoretical constructs of great import and generality. (shrink)
William Paley ( Natural Theology , 1802) developed the argument-from-design. The complex structure of the human eye evinces that it was designed by an intelligent Creator. The argument is based on the irreducible complexity ("relation") of multiple interacting parts, all necessary for function. Paley adduces a wealth of biological examples leading to the same conclusion; his knowledge of the biology of his time was profound and extensive. Charles Darwin’s Origin of Species is an extended argument demonstrating that the "design" of (...) organisms can be explained by natural selection. Moreover, the dysfunctions, defects, waste, and cruelty that prevail in the living world are incompatible with a benevolent and omnipotent Creator. They come about by a process that incorporates chance and necessity, mutation and natural selection. In addition to science, there are other ways of knowing, such as art, literature, philosophy, and religion. Matters of value, meaning, and purpose transcend science. (shrink)
Today, more corporations disclose information about their environmental performance in response to stakeholder demands of environmental responsibility and accountability. What information do corporations disclose on their websites? This paper investigates the environmental management policies and practices of the 200 largest corporations in the world.

Corporate America is institutionalizing ethics through a variety of structures, systems, and processes. This study sought to identify managerial perceptions regarding the institutionalization of ethics in organizations. Eighty-six corporate level marketing and human resource managers of American multi-national corporations responded to a mail survey regarding the various implicit and explicit ways by which corporations institutionalize ethics. The results revealed that managers found ethics to be good for the bottom line of the organizations, they did not perceive the need for additional (...) formalization of ethics, and that they perceived implicit forms of institutionalizing ethics (e.g., leadership, corporate culture, top management support) to be more effective than the explicit forms of institutionalizing ethics (e.g., ethics ombudspeople, ethics committees, ethics newsletters). Implications of the survey and future research directions conclude the paper. (shrink)

: The history of modern feminist political theories is often framed in terms of the already existing theories of a number of radical nineteenth-century men philosophers such as James Mill, John Stuart Mill, Charles Fourier, Karl Marx, and Friedrich Engels. My argument takes issue with this way of framing feminist political theory by demonstrating that it rests on a derivation that remains squarely within the logic of malestream political theory. Each of these philosophers made use of a particular discursive trope (...) that linked the idea of women's emancipation with the idea of social progress. I argue that this trope reproduced the masculinist signification and symbolism inherent in their particular political philosophies. I argue for a more positive, less masculinist, account of the history of feminist political thought. (shrink)
: Liberal philosopher James Mill has been understood as being unambiguously antifeminist. However, Terence Ball, supposedly informed by a feminist perspective, has argued for a new interpretation. Ball has reconceptualized Mill as a feminist and the sole source of the feminism of his son (J. S. Mill), suggesting a revision of the received wisdom about their relationship to the development of nineteenth century feminist thought. This paper takes issue with Ball's "new interpretation" and its presumed feminist basis.
Abstract This paper reports the results obtained in an aid project designed to improve transport in the municipal area of Jocotán (Guatemala). The rural road network of an area occupied by indigenous people was analysed and a road chosen for repair using the labour-intensive method–something never done before in this area. The manpower required for the project was provided by the population that would benefit from the project; the involvement of outside contractors and businesses was avoided. All payment for labour (...) went into the pockets of the local people. The small earth movements made and the use of local materials guaranteed the project’s environmental sustainability, while the on-site training of the local community prepared its members for the continued maintenance of the road, thus investing the project with social sustainability.

In discussing the works of 16th-century theorists Francisco de Vitoria and Alberico Gentili, this article examines how two different conceptions of a global legal community affect the legal character of the international order and the obligatory force of international law. For Vitoria the legal bindingness of ius gentium necessarily presupposes an integrated character of the global commonwealth that leads him to as it were ascribe legal personality to the global community as a whole. But then its legal status and (...) its consequences have to be clarified. For Gentili on the other hand, sovereign states in their plurality are the pinnacle of the legal order(s). His model of a globally valid ius gentium then oscillates between being analogous to private law, depending on individual acceptance by states and being natural law, appearing in a certain sense as a form rather of morality than of law.

Francisco Suárez (1548-1617) publicou em 1597 sua obra-prima em metafísica, as Disputationes metaphysicae. Na trigésima terceira Disputa – o objeto deste artigo – Suárez defende primeiramente a substância sobtrês aspectos: como “ens per se” (uma entidade independente), como o que permanece no tempo, e como o suporte fundamental de acidentes. Secundariamente, ele utiliza três distinções com o objetivo de articular a noção de substância: substâncias completas e incompletas, substâncias perfeitas e imperfeitas, e a distinção entre substância primeira e substância (...) segunda. Uma gota d’água, por exemplo, é uma primeira substância completa, mas relativamente imperfeita. Em comparação com ela, a alma humana é uma primeira substância incompleta, mas mais perfeita. A regra é: quanto mais perfeita, tanto mais incompleta. Por trás dessas distinções, Suárez elabora um aspecto dinâmico da substância. A abordagem é aristotélica, sem incluir aspectos de filosofia social ou filosofia existencial. (shrink)
This article intends to argue that Francisco de Vitoria’s conception of the Spanish Conquest of America is based upon notions that stem from various sources of the 14th and 15th Century. One of his most important source is the Opus septipertitum de contractibus, written by the German theologian Conradus Summenhart, whom Vitoria quotes frequently. By comparing both thinkers it can be shown that Vitoria’s basic terminology concerning rights and dominion is in greatly indebted to Summenhart’s account.

A world without individual entities? An advice to not to extract immediate ontological consequences from quantum theory. Should we assume a world without individual entities? I pledge not to extract immediate ontological consequences from quantum theory. My intention is to focus on the complexity of ontological concepts commonly associated with quantum theory. Using as an example the compatibility of EPR correlations with the existence of individual entities, it is shown that an absolute rejection of an ontological category, based on some (...) aspects of the formalism of quantum theory, does not seem reasonable. A consequence of this argument is that the common sense view – the world is composed of individual entities – can be maintained, despite of the particularities of quantum mechanics. (shrink)
The objective of this paper is analyzing to which extent the multiverse hypothesis provides a real explanation of the peculiarities of the laws and constants in our universe. First we argue in favor of the thesis that all multiverses except Tegmark’s “mathematical multiverse” are too small to explain the fine tuning, so that they merely shift the problem up one level. But the “mathematical multiverse" is surely too large. To prove this assessment, we have performed a number of experiments with (...) cellular automata of complex behavior, which can be considered as universes in the mathematical multiverse. The analogy between what happens in some automata (in particular Conway’s “Game of Life") and the real world is very strong. But if the results of our experiments can be extrapolated to our universe, we should expect to inhabit—in the context of the multiverse—a world in which at least some of the laws and constants of nature should show a certain time dependence. Actually, the probability of our existence in a world such as ours would be mathematically equal to zero. In consequence, the results presented in this paper can be considered as an inkling that the hypothesis of the multiverse, whatever its type, does not offer an adequate explanation for the peculiarities of the physical laws in our world.

This talk, delivered at De l''autopoièse à la neurophénoménologie: un hommage à Francisco Varela; from autopoiesis to neurophenomenology: a tribute to Francisco Varela, June 18–20, at the Sorbonne in Paris, explicates several links between Varela''s neurophenomenology and his biological concept of autopoiesis.
Francisco Varela’s work is a monumental achievement in 20th century biological and biophilosophical thought. After his early collaboration in neo-cybernetics with Humberto Maturana (“autopoiesis”), Varela made fundamental contributions to immunology (“network theory”), Artificial Life (“cellular automata”), cognitive science (“enaction”), philosophy of mind (“neurophenomenology”), brain studies (“the brainweb”), and East- West dialogue (the Mind and Life conferences). In the course of his career, Varela influenced many important collaborators and interlocutors, formed a generation of excellent students, and touched the lives of (...) many with the intensity of his mind, the sharpness of his wit, and the strength of his spirit. In this essay, I will trace some of the key turning points in his thought, with special focus on the concept of emergence, which was always central to his work, and on questions of politics, which operate at the margins of his thought. I will divide Varela’s work into three periods – autopoiesis, enaction, and radical embodiment – each of which is marked by a guiding concept; a specific.. (shrink)
Interpreters disagree on the origin that Francisco Suárez assigns to political obligation and correlative political subjection. According to some, Suárez, as other social contract theorists, believes that it is the consent of the individuals that causes political obligation. Others, however, claim that for Suárez, political obligation is underived from the individuals' consent which creates the city. In support of this claim they invoke Suárez's view that political power emanates from the city by way of "natural resultancy". I argue that (...) analysis of Suárez's less studied De voto and De iuramento reveals that, for Suárez, consent causes both the city and the citizen's political obligation. Moreover, close inspection of the notion of causation by natural resultancy within Suárez's metaphysics shows that what emanates from the body politic in this fashion is not, as claimed, political subjection and political obligation, but rather the city's right to self-mastership. Because for him political obligation does originate in consent it is not incorrect to regard Suárez as a social contract theorist. (shrink)
Empirical research on Rational Choice Theory has brought up two focus of the economics laws problem. On one hand, we find the authors who state that the neoclassical economics laws are explanatory and predictive on specific cases: in transparent contexts in which the standard rationality operates successfully. On the other hand, we find the authors who state that the descriptive theories of the rational choice opens up a research path in which fundamental principles of the neoclassical building could be questioned. (...) Both view points have generated an important standard Rational Choice Theory revision what has produced the so called descriptive view point . It implies understanding that most of the choices take place under risky or uncertainty conditions and, that, these choices are far more complex than the normative Rational Choice Theory supposes. This article's main goal is to expand the descriptive point of view in rational choice, theorizing how some factors, coming from the social and cultural environment, operate within the rational choice. Into space of this research essay we find the debatable question of whether these sort of proposals expands the explanation of the deviation of the rational choice normative theory, and that, of the disturbing causes of the microeconomics laws, or they call into question fundamental principles of these laws and therefore they are opening the possibility to focus some economics issues in a new different manner.

The Renaissance sceptic and medical doctor Francisco Sanchez has been rather unduly neglected in scholarly work on Renaissance scepticism. In this paper I discuss his scepticism against the background of the ancient distinction between Academic and Pyrrhonian scepticism. I argue that Sanchez was a Pyrrhonist rather than, as has been claimed in recent years, a mitigated Academic sceptic. In keeping with this I shall also try to show that Sanchez was crucially influenced by the ancient medical school of empiricism, (...) a school closely allied with Pyrrhonism. (shrink)
It is with great sadness that I record the death of Francisco Varela, who passed away at his home in Paris, on May 28, 2001. With his passing, the science of consciousness has lost one of its most brilliant, original, creative, and compas- sionate thinkers.
During the seventeenth century Francisco Suárez was considered one of the greatest philosophers of the age. He was the last great Scholastic thinker and profoundly influenced the thought of his contemporaries within both Catholic and Protestant circles. Suárez contributed to all fields of philosophy, from natural law, ethics, and political theory to natural philosophy, the philosophy of mind, and philosophical psychology, and--most importantly--to metaphysics, and natural theology. Echoes of his thinking reverberate through the philosophy of Descartes, Locke, Leibniz, and (...) beyond. Yet curiously Suárez has not been studied in detail by historians of philosophy. It is only recently that he has emerged as a significant subject of critical and historical investigation for historians of late medieval and early modern philosophy. Only in recent years have small sections of Suárez's magnum opus, the Metaphysical Disputations, been translated into English, French, and Italian. The historical task of interpreting Suárez's thought is still in its infancy. The Philosophy of Francisco Suárez is one of the first collections in English written by the leading scholars who are largely responsible for this new trend in the history of philosophy. It covers all areas of Suárez's philosophical contributions, and contains cutting-edge research which will shape and frame scholarship on Suárez for years to come--as well as the history of seventeenth-century generally. This is an essential text for anyone interested in Suárez, the seventeenth-century world of ideas, and late Scholastic or early modern philosophy. (shrink)
Managers’ commitment to contribute to sustainable development holds the key to their long-term business success and may be a source of competitive advantage. The managerial perception of business ethics is influenced by the level of moral development and personal characteristics of managers. These perceptions are also shaped by forces existing in the environment of the firm, including available resources, societal expectations, sector, and regulations. The resource-based perspective can thus contribute to the analysis of ethical issues offering important insights on how (...) they can influence the environmental strategy of the firm. The findings of this study show that firm resources have a strong influence on business managers’ ethical attitudes. In addition, the application of resource-based rationales to ethical issues can be justified in the following several ways: it influences a managerial perception of natural environment as a competitive opportunity, it requires investments of financial and human resources, flexibility and speed in the adaptation to environmental changes, and it creates new resource-based opportunities through changes in prevention pollution technology, policy process, and market forces.

Context: Francisco Varela and Humberto Maturana worked closely together for several short episodes and wrote joint publications during the 1970s and 1980s. After that their respective paths in life diverged. Problem: What is the common ground and what are the differences between these two authors with respect to their lives and aims? Method: The author reconstructs their common history in the form of personal reflections and conversations with Varela. Results: The personal reflections reveal the intellectual path Maturana took to (...) develop his way of thinking, in particular his fascination with explanatory processes and the phenomenon of life. The conversations with Varela portray him as a man of great “cognitive autonomy,” whose career started with the intention to study “psychism in the universe.” For Varela it seemed possible, through meditation, to reach transcendental reality as something that exists externally to the living of human beings and that can be known as such. Maturana, by contrast, claims that there is no way to refer to such a universal truth. Rather, human beings generate all the worlds they live in. Implications: While the two men collaborated in both teaching and writing, they eventually created two different constructivist approaches driven by a different set of questions. Constructivist content: Both Humberto Maturana and Francisco Varela have decisively contributed to constructivist approaches. (shrink)

According to evolutionist FranciscoAyala, Darwin’s greatest achievement was to show that the organized complexity of living things could be brought about without recourse to a designing intelligence. Given this view of Darwin’s achievement, what evolutionary biology has come to mean by “evolution” is an unintelligent or blind form of it. This was brought home to me two years ago at a debate in which I participated. I was invited, along with my colleague and friend Michael Behe, to (...) debate Darwinists Kenneth Miller and Robert Pennock at the American Museum of Natural History in Manhattan. The debate was initially titled “Blind Evolution or Intelligent Design?” Yet, when the debate actually took place on April 23, 2002, the program bulletin distributed at the event quietly dropped the word “blind” and titled the debate simply “Evolution or Intelligent Design?” The original title was more accurate. Intelligent design, the view for which Behe and I were arguing, is opposed to blind evolution, not to evolution simpliciter. (shrink)
The combined use of computers and telecommunications and the latest evolution in the field of Artificial Intelligence brought along new ways of contracting and of expressing will and declarations. The question is, how far we can go in considering computer intelligence and autonomy, how can we legally deal with a new form of electronic behaviour capable of autonomous action? In the field of contracting, through Intelligent Electronic Agents, there is an imperious need of analysing the question of expression of consent, (...) and two main possibilities have been proposed: considering electronic devices as mere machines or tools, or considering electronic devices as legal persons. Another possibility that has been frequently mentioned consists in the application of the rules of agency to electronic transactions. Meanwhile, the question remains: would it possible, under a Civil Law framework, to apply the notions of “legal personhood” and “representation” to electronic agents? It is obvious that existing legal norms are not fit for such an endeavouring challenge. Yet, the virtual world exists and it requires a new but realistic legal approach on software agents, in order to enhance the use of electronic commerce in a global world. (shrink)
In the fiftieth disputation of his Disputationes metaphysicae (1597), Francisco Suárez distinguishes three notions of time. Suárez offers an account of the ways in which the predicate ‘when’ can be taken and presents a more general perspective based on the principle of duration, rather than the Aristotelian definition of time. His view differs from Aristotle’s and Aquinas’ account because Suárez emphasizes that time cannot be reduced to the number of the movement of the last sphere in the Aristotelian model (...) of the cosmos. The intrinsic duration of a thing is its true time; this duration can be taken in an absolute or a relative sense. In an absolute sense, intrinsic time is an internal property of a thing that cannot be really distinguished from existence itself and cannot be compared with other durations. In a relative sense, we can imagine this intrinsic duration as filling up a certain interval within an infinitely extended imaginary succession. This imaginary succession is an ens rationis. The third concept of time is the Aristotelian notion: this is just an extrinsic time, a measurement of one movement by means of a comparison with another movement, especially the motion of the last sphere. Finally, in order to show the value of Suárez’s insights, I compare them with some contemporary issues in the analytic philosophy of time. (shrink)
FranciscoAyala and others have argued that recent genetic evidence shows that the origins of the human race cannot be monogenetic, as the Church hastraditionally taught.

In attempting to integrate the authors' proposed model with results from analogous human event-related potential (ERP) research, we found difficulties with: (1) its apparent disregard for supraordinate representations at posterior multimodal association cortices, (2) its failure to address contextual task effects, and (3) its strict architectural dichotomy between memory storage and control functions.

Łukasiewicz three-valued logic Ł3 is often understood as the set of all 3-valued valid formulas according to Łukasiewicz’s 3-valued matrices. Following Wojcicki, in addition, we shall consider two alternative interpretations of Ł3: “well-determined” Ł3a and “truth-preserving” Ł3b defined by two different consequence relations on the 3-valued matrices. The aim of this paper is to provide (by using Dunn semantics) dual equivalent two-valued under-determined and over-determined interpretations for Ł3, Ł3a and Ł3b. The logic Ł3 is axiomatized as an extension of Routley (...) and Meyer’s basic positive logic following Brady’s strategy for axiomatizing many-valued logics by employing two-valued under-determined or over-determined interpretations. Finally, it is proved that “well determined” Łukasiewicz logics are paraconsistent. (shrink)
Ever since it was annexed from northern Mexico in 1848, San Francisco has catered to tourists attracted to its good year-round weather, natural splendor, as well as its licentious entertainment industry and, since the 1950s, the buoyancy of its lesbian and gay community. The author looks at the growth and vibrancy of alternative lifestyles in San Francisco, arguing that the visibility of the queer community there is not the result of general tolerance in the Western outpost but, paradoxically, (...) the outcome of a struggle between the lesbian, gay, and transgendered residents of the city and the repressive local, state, and federal agencies whose harassment of the alternative communities, culminating in the 1930s and 1940s in frequent bar-raids, arrests, and the “war on vice,” brought about the queer community’s politicization and grovving militancy.

Este libro nos presenta un «Ortega desde dentro», es decir, no como él había observado a Goethe, con catalejo, sino reconstruido a base de sus testimonios personales esparcidos en artículos, libros, cartas, clases y conferencias, a los que habría que sumar los que sobre él dejaron familiares, colaboradores, discípulos, amigos y enemigos. Estamos pues ante una biografía con ropaje autobiográfico, no sólo de su persona, sino también de su obra, íntimamente unidas a la España de la primera mitad del siglo (...) xx, a la que quiso guiar bajo los más diversos regímenes antes de ser arrastrado por su tragedia como nación. En cierto modo, es la historia de un amor imposible, porque la España que soñó no existía y puede que ni siquiera llegue a existir. Sin embargo y paradójicamente, también es la historia de cómo Ortega, al iluminar sus carencias, logró dejar su impronta en ella. (shrink)

Francisco Valles, also known as ‘The Divine Valles’, was most probably the greatest Spanish physician of the Renaissance and succeeded Andreas Vesalius, whom he knew well, as the personal doctor of Philip II of Spain. Valles studied in Alcalá and wrote several works, among which the influential Controversiarum medicarum et philosophicarum. The importance of Valles’s contribution to the debate concerning the number, the specific tasks, and the localization of the internal senses in Aristotle and in Galen is attested by (...)

España, inicios del siglo XX. José Ortega, armado de razón, busca un ideal que guíe su vida, oriente su acción pública e ilumine lo que le rodea. En su demanda se enfrentará con Don Quijote, Unamuno o Baroja; descifrará el neokantismo, la fenomenología, el psicoanálisis; investigará la leyenda milenarista, la prehistoria del criticismo, la anatomía del alma; descubrirá la mujer, la política, el compromiso; predicará el socialismo, la construcción de Europa, la recreación de España y recorrerá Castilla, Marburgo o Asturias (...) para asentarse en El Escorial, donde ya estaba.
