This article includes a study about the preface of Moreh ha-Moreh, a philosophical commentary on Guide for the Perplexed written by Sem Tob ibn Falaquera at the end of XIIIth century. In this introduction Sem Tob ibn Falaquera defends Maimonides and his works. In addition, he exposes his opinion about different subjects, like the nature, the determining factors and limits of philosophical labour or the harmony between reason and faith.

In his major philosophical opus, Kevod Elohim , written in Hebrew, Joseph ben Shem Tov investigates the summum bonum of man, which consists in the similarity to God's perfection called the "Glory of God" insofar as it can be realized by human nature. Opinions are divided, however, as to the nature of this greatest good. Some Jewish scholars claim that man's final purpose is in the observance of the 613 commandments of the Torah. According to the philosophers, the proofs (...) of Aristotle show irrefutably that man's highest happiness is in the grasping of cognition through reason. Other Jewish scholars assert that the mysteries of the Torah can be explored through philosophy and therefore the Torah and the sciences fulfill in principle the same purpose. This position, however, is objectionable to some believers on the ground that it denies the divine character of religion. On the other hand, to deny the proofs of Aristotle would be to coerce the findings of reason. If religion is the supreme good, it cannot contradict reason. Since the truth cannot be in conflict with the truth, Joseph's task is to compare, for the first time, the Nicomachean Ethics of Aristotle with the Torah to determine to what extent they agree or conflict. His method is to assemble all statements of Aristotle and his commentators on this subject and to submit them to critical analysis. Joseph's motivation is to justify the pursuit of Greek science, especially in view of his father Shem Tov ibn Shem Tov's virulent repudiation of philosophy, and to guide the perplexed of his generation who could not reconcile Greek wisdom with their faith. Joseph finds that the speculative eudemonia of Aristotle accords with the Torah. In an innovative interpretation of the Ethics, he reveals that Aristotle believed in individual providence over those who perfected their intellect and over those who practiced the ethical virtues. Joseph also identifies the study of Torah with the activity of speculation similar to the activity of the Separate Intellects. He finds no basis, however, in Aristotle's writings for the immortality of reason. Since the religious imperative grants immortality, it is infinitely greater than the eudemonia of reason. Thus, from a position of rapprochement between science and faith, Joseph considers them under the aspect of eternity and emerges with a complete denial of any ultimate resemblance between the two spheres.

Theatrical improvisation is a joyful, creative, and playful activity of discovery and a spontaneous process. It seems to be the opposite of teaching, which requires proper planning and advance thinking and seems a very “serious business” that deals with values and knowledge. Improvisation is shaped by flexibility and by transformative and equal relations among the participants. In contrast, there is in education usually a very clear hierarchy of teacher and pupils, and the relationships are mostly managed in a one-way direction. (...) This seemingly reasonable comparison of opposites can be continued and developed. If we look beyond these superficial, stereotypical, and binary images of improvisation and teaching.. (shrink)

Oxygenic photosynthesis is the principal producer of both oxygen and organic matter on earth. The primary step in this process—the conversion of sunlight into chemical energy—is driven by four multi‐subunit membrane protein complexes named photosystem I, photosystem II, cytochrome b6f complex and F‐ATPase. Photosystem I generates the most negative redox potential in nature and thus largely determines the global amount of enthalpy in living systems. The recent structural determination of PSI complexes from cyanobacteria and plants sheds light on the evolutionary (...) forces that shaped oxygenic photosynthesis. The fortuitous formation of our solar system in a space plentiful of elements, our distance from the sun and the long time of uninterrupted evolution enabled the perfection of photosynthesis and the evolution of advanced organisms. The available structural information complements the knowledge gained from genomic and proteomic data to illustrate a more precise scenario for the evolution of life systems on earth.

The Arabic philosophical fable _Hayy Ibn Yaqzan _is a classic of medieval Islamic philosophy. Ibn Tufayl, the Andalusian philosopher, tells of a child raised by a doe on an equatorial island who grows up to discover the truth about the world and his own place in it, unaided—but also unimpeded—by society, language, or tradition. Hayy’s discoveries about God, nature, and man challenge the values of the culture in which the tale was written as well as those of every contemporary society. (...) Goodman’s commentary places _Hayy Ibn Yaqzan _in its historical and philosophical context. The volume features a new preface and index, and an updated bibliography. “One of the most remarkable books of the Middle Ages.”—_Times Literary Supplement_ “An enchanting and puzzling story.... The book transcends all historical and cultural environments to settle upon the questions of human life that perpetually intrigue men.”—_Middle East__ Journal_ “Goodman has done a service to the modern English reader by providing a readable translation of a philosophically significant allegory.”—_Philosophy East and West_ “Add[s] bright new pieces to an Islamic mosaic whose general shape is already known.”—_American Historical Review_.

A translation of the Fons vitae of Solomon ibn Gabirol (born 1021/1022), who was the first Jewish philosopher in Spain. In the Fons vitae, Gabirol argues that there is a sensible and an intelligible world. These doctrines profoundly influenced medieval Christian thinkers. Because of the Fons vitae, Gabirol is today widely recognized as one of the greatest Jewish Neoplatonists.
