In the 1940s, Erwin Schrödinger attempted to tackle the eternal question "What is Life?" from the perspective of the "naïve physicist." The result is this short book, which has influenced generations of scientists, sparked much controversy and become a classic. What Is Life? appears in Hebrew for the first time, accompanied by an epilogue by Prof. Avshalom Elitzur, who demonstrates to what extent Schrödinger's insights are relevant eighty years after the first publication of the essay.

Against the backdrop of war and the political crisis in Israel, volume 73 of Iyyun turns a philosophical spotlight on the concept of law, which has become acute in contemporary Israeli discourse. The articles in this volume deal with a variety of systems of laws, which stress the fundamental difference between theoretical and normative laws, and the understanding that the validity of the law and its compulsory nature are heterogenic by nature.

Gottfried Wilhelm Leibniz (1646-1716) was a polymath of Renaissance culture. His 1710 Essais de Théodicée , the longest work published in his lifetime, was a final and concluding phase in his life-long theological-philosophical journey. It constituted a milestone in the diplomatic and intellectual effort to restore the religious and political peace in Europe, and is, above all, a key philosophical work.

Dan Perry was born and raised on Mount Carmel. From childhood, encouraged by his father, he often wandered on the mountain, getting to know its surroundings and connecting with its flora and fauna. As an adult, he became involved in the newly formed Nature Conservation Authority - first as a tour guide, and later as part of the Society for the Protection of Nature. In 1965 he started working within the Nature Conservation Authority, established in 1964, as an inspector in the Galilee as part of a collaboration between the Society and the Authority. Immediately after the Six-Day War, he established a magnificent system of nature reserves on the Golan Heights. He ran the Hermon Development Authority which established the Hermon site, and then joined the Authority's management and held a variety of positions. This unique volume includes color photographs.

Atlas of East Galilee Caves is published in a challenging period for the Upper Galilee, with hopes for a swift return to routine in this beautiful and region, bountiful with caves. The Atlas is published following studies and surveys conducted over the past decades. The boundaries of the area defined in the Atlas are the Hula Valley in the east, the border of Lebanon in the north and northwest, the sources of the streams flowing eastward in the west and the Issachar highlands in the south. The Atlas presents the basic data of the caves, and contains a concise multidisciplinary overview of what is known about them from a geological, historical, archaeological and biological point of view. The data is accompanied by plans and illustrations that expand the overall picture of each cave.

In 1980, the Italian publisher Einaudi wanted to publish a series of personal anthologies of its authors. Primo Levi quickly arose to the challenge and submitted La ricerca delle radici ( The Search for Roots ): thirty excerpts from thirty masterpieces of world literature, accompanied by thirty short introductions he wrote. Every such introduction is a brilliant commentary on the work, and a reflection of Primo Levi himself - as a kind of self-portrait, in which the painter produces his collage from materials created by others. These excepts - published for the first time in Hebrew - reveal some of the important ethical and aesthetic influences on Primo Levi and his work. Levi quotes from Job, Lucretius, Rabelais‏, Babel, Shalom Aleichem, de Saint-Exupéry and more, but also from Darwin's On Origin of Species and even from Practical Organic Chemistry. Thus, it is possible to trace his extensive and diverse, humanistic and scientific education, the roots from which his unique literary work grew.

Although frequently observed in natural habitats across Israel, the true nature of the "strange growths" (galls) that appear on various plants is not always clear. Insect-induced plant galls are actually the most intimate way in which animals feed on plants. This book reveals to naturalists and scientists one of the most impressive and conspicuous groups among gall-forming insects: aphids that form galls on wild pistachio (Pistacia). The gall serves as an incubator for the aphids, providing them with a rich food supply and shelter from natural enemies and abiotic factors. Several aphid generations develop in galls from spring to fall. During these months, the gall functions as a dynamic and complex multitrophic ecological (mini) system, including pathogens, competitors, parasites, and predators. The first part of the book describes the multi-disciplinary information on the biology and ecology of the aphids and gall system from molecular, anatomical, physiological, biochemical, behavioral, biogeographic, and evolutionary points of view. The second part of the book is in fact an informative and photographic guide to all the aphid-induced galls on wild pistachios in Israel.

In his two masterworks, Mishneh Torah and The Guide for the Perplexed , Maimonides explicitly articulates a dual crisis: the disintegration of the Halakhic tradition and the erosion of the esoteric knowledge of the Torah. This study presents a novel interpretation of Maimonides’ crisis proclamations and the narratives linked to them. It primarily analyzes how Maimonides crafted a discourse of crisis, illuminating this through a comparison with earlier discourses in the Jewish canon and parallel crisis narratives in Islamic sources. The key question it seeks to answer is: why did Maimonides prominently employ this discourse in his works? The exploration of crisis discourse in Maimonides’ work reveals how he introduces a marked internal tension in each of his two major works. On the one hand, he declares his commitment to both the halakhic tradition and the esoteric knowledge tradition, even as he retrospectively reshapes them. On the other hand, he emphasizes the urgent need for reforming these traditions to confront the rupture they have undergone. This study demonstrates that in both Mishneh Torah and The Guide for the Perplexed , Maimonides portrays the process of breaking and refashioning tradition as an act of loyalty to these traditions during a time of crisis.

The "Possibility of Dialogue" issue was originally designed as a tribute to the dialogic philosophy of Martin Buber on the centenary of his groundbreaking book I and Thou ( Ich und Du 1923). Since the planning of the issue, Israeli society has gone through dramatic upheavals, and most recently, on October 7th, a brutal massacre of many Israeli citizens by Hamas, followed by a bitter war whose end is still not in sight. The 72 issue (Fall 2023) of Iyyun is now published in a painful, violent and bloody country. At a time when the possibilities of dialogue have collapsed and disappeared almost entirely from the public sphere, the necessity of philosophical discussion is essential and urgent. The title "Possibility of Dialogue" reminds us that the existence of dialogue is not a matter of course. Dialogue is a type of human possibility, a certain form of conduct - of speaking and listening, of living together - in the linguistic space, which can be realized in different contexts and in different ways; However, there is no necessity for its realization. The fact that through the common language we communicate with others, say things, convey messages, achieve achievements, is not a sufficient condition for the realization of the dialogical possibility. But, if communicative success is not the criterion for dialogue, what is its meaning? How do we approach this inquiry? A subscription can be purchesed through this link or use the online form .

This book presents a comprehensive selection, translated for the first time into Hebrew, of the Latin works of Francesco Petrarch (1304-1374), the "father of humanism" and a pivotal precursor to the Italian Renaissance. The compilation includes some of Petrarch's renowned personal letters, such as the pair he addressed to the Roman orator and philosopher Cicero. It features a therapeutic-autobiographical dialogue in which he engages with his spiritual father, Saint Augustine, challenging the latter's strict worldviews. The selection also encompasses an Invective against the dominant Aristotelian philosophy of his era, asserting the preeminence of classical rhetoric over philosophy; a novella presenting his interpretation of the closing story of the Decameron ; and a portion of his Latin poetry, through which he sought to revive the works of the great Roman poet Virgil. Through these writings, Petrarch fostered the emergence of a new secular culture on the cusp of the modern era—one that emphasizes humanity and life in this world—and set the stage for the remarkable creative surge of the Italian Renaissance.
