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.

It is an intimate experience for us to think, to understand and to perceive things as being identical to themselves, and to suppose, consequently, that things are truly “what” they are. Something is always conceived as itself. The given is given full of itself in all its modifications. For instance, I can think or perceive partially some lips, I can see them almost in their whole or in some of their aspects, or just see them disappear. But it does not (...) seem to be possible to think or to perceive a given as almost itself, as an aspect or as part of itself. It is the aim of this work to study the assumptions and conditions for the original position of sameness in experience, just as it occurs in the synthesis of the datum singular and distinct. The polarization of single tone (einstimmig) intentional rays in an αvτó already contains the aporiae peculiar to the experience of the identical, whose revelation shall lead us, on the one hand, to one of the nuclei of the analysis of passive synthesis, and, on the other hand, to point up how critical revision of the numerical or extensional model of self-identity is for the unity of meaning. Then, it will be a question of pointing out the reasons why in a phenomenology of identity, the renunciation of the phenomenological legitimacy of the αvτó as a guarantee for the different positions of identity must be observed.

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.

José Otero Espasandín (1900-1987) was an important science popularizer in Argentina during the 1940´s, who belonged to the Misiones Pedagógicas (Educational Missions) group in Spain. This paper presents his biography and his work as a science and technology popularizer. It focused on his features, value and significance for that period.

Medical stem cell research is currently the cause of much moral controversy. Those who would confer the same moral status to embryos as we do to humans consider that harvesting such embryonic cells entails sacrificing embryos. In this paper, the author analyses critically the arguments given for such a perspective. Finally, a theory of moral status is outlined that coherently and plausibly supports the use of embryonic stem cells in therapeutic research.

Sobre el libro: El presente libro recoge las ponencias presentadas en la reunión anual del Seminario Spinoza que tuvo lugar en la Facultad de Filosofía de la UNED los días 13 y 14 de marzo de 2009, así como la presentación del cuadro de Espinosa pintado por Sorolla procedente de la Donación Simarro y perteneciente al fondo artístico de la Universidad Complutense, que tuvo lugar en El Escorial en el verano de 2008. Los trabajos se articulan en cuatro apartados: la (...) política, la ciencia, la proyección de Espinosa en la Ilustración y la iconografía de Espinosa, y sitúan a Espinosa en su siglo, destacando su carácter anómalo en relación con el resto de autores de su entorno. Espinosa no se adaptó a la crisis, sino que se esforzó por comprenderla sin ceder en sus ideales, lo que permitió que las ilusiones renacentistas se desarrollaran en la ilustración, superando el hiato de la crisis barroca.

Œuvre de maturité de François Suarez (1548-1617), Des lois et du Dieu législateur a été publié en latin en 1612. Parmi les dix livres que comprend cet ouvrage, nous avons choisi de présenter pour la première fois les deux premiers en langue française. À partir de l'héritage retravaillé de la philosophie politique antique et médiévale, Suarez élabore une théorie originale de la loi et de la communauté en renouvelant leur rapport à l'éthique et à la jurisprudence. Dans une période marquée (...) notamment par la controverse de Valladolid (1550) et la Contre-Réforme, l'auteur redéfinit le contenu et la finalité des concepts fondamentaux de la théorie politique (l'état de nature, le droit naturel, le droit subjectif, la loi naturelle, le pacte social, la souveraineté, l'État et le droit des gens) en les articulant à une compréhension historique de l'homme conçu comme être libre, raisonnable et fini. Suarez instaure ainsi les conditions d'un basculement du théologico-politique dans la modernité dont les effets se feront sentir, entre autres, chez Grotius et l'École du droit naturel. Les conséquences de ce mouvement seront perceptibles jusqu'au XVIIIe siècle avec Wolf. Des lois et du Dieu législateur permet précisément d'apprécier à sa juste mesure la place privilégiée qu'il convient de redonner à la théorie suarézienne de la loi dans l'histoire de la pensée politique.
