Much of the writing of and about the twelfth-century rabbi, philosopher, and theologian Moses Maimonides is addressed to an elite audience of philosophers and intellectuals. Here, Ralph Lerner's exploration of Maimonides' popular writings reveals that the education of the common man was one of the great teacher's chief concerns. Lerner describes the brilliant and sometimes wily ways in which Maimonides sought to break through the despair and superstition that gripped the Jewish people's minds, without sacrificing the dignity and core (...) of his message. These writings—presented here in uncommonly accurate, mostly new translations—also reveal that Maimonides was willing to risk the scorn of his contemporaries to enlighten both his own and future generations. By addressing the writings of Maimonides' disciples, including Shem Tov ben Joseph Ibn Falaquera in the mid-thirteenth century and Joseph Albo in the fifteenth century, Lerner shows how this technique was passed on. In striking contrast to the Enlightenment of the eighteenth century, Maimonides' enlightenment is premised on the inequality of understandings and other differences between the elite and the common people. Instead of scorning the past, Lerner shows, Maimonides' enlightenment invests it with a new and ennobling dignity. A valuable reference for students of political philosophy and Jewish studies, Lerner's elegantly written book also brings to life the richness and relevance of medieval Jewish thought for all those interested in the Jewish tradition.

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.
