The purpose of our lives is to grow step by step toward a fundamental transformation. Instead of always seeking some form of gratification, we can learn to give to others with no self-interest at all. The is the essential teaching of the Kabbalah portrayed in these essays by Baal Hasulam – the greatest modern explicator of Kabbalah. Rabbi Gottlieb provides an illuminating commentary as a living Chassidic rebbe devoted to the practice and teaching of Baal Hasulam’s spiritual path.

This article presents a thorough analysis of the enormous popularity of Kabbalah in recent years, its roots, and its purpose. The greatest Kabbalist of the 20th century, Rabbi Yehuda Ashlag, author of The Sulamcommentary on The Zohar, predicted the breakout of the present-day world crisis and explained that almost two thousand years ago, The Zohar had already predicted that the end of the 20th century would present a crossroads where humanity would have to choose its direction. Now, at (...) the beginning of the 21st century, The Zohar's predictions and Ashlag's interpretation, as well as the suggested solution, all merit a thorough examination. (shrink)

In a recent article, Azzouni has argued in favor of a version of formalism according to which ordinary mathematical proofs indicate mechanically checkable derivations. This is taken to account for the quasi-universal agreement among mathematicians on the validity of their proofs. Here, the author subjects these claims to a critical examination, recalls the technical details about formalization and mechanical checking of proofs, and illustrates the main argument with aanalysis of examples. In the author's view, much of mathematical reasoning presents genuine (...) meaning-dependent mathematical characteristics that cannot be captured by formal calculi. ‘…there is a conflict between mathematical practice and the formalist doctrine.’ [Kreisel, 1969, p. 39].

I would like to argue that to a large extent universities are themselves to blame for their failure to respond adequately to external pressures of the day. Barring the work of a few exceptional departments and individuals here and there, universities are incapable of addressing precisely those problems that most preoccupy our societies nowadays. Granted, universities rightly regard themselves as playing a key role in preserving intellectual, academic and cultural traditions. This, however, should not be taken to be an acceptable (...) excuse for not dealing with fundamental social injustices and discrepancies - problems often deemed to lie outside the scope of a university's legitimate interests. Since universities are by far the most important institutions in any modern society entrusted with the task of creating knowledge, they should also strive to apply the knowledge created there to major social issues at any given time. This paper substantiates this thesis through some examples, and discusses its bearing on the future of the university curriculum. (shrink)

The Many-Worlds Interpretation (MWI) is an approach to quantum mechanics according to which, in addition to the world we are aware of directly, there are many other similar worlds which exist in parallel at the same space and time. The existence of the other worlds makes it possible to remove randomness and action at a distance from quantum theory and thus from all physics.

This is a philosophical paper in favor of the many-worlds interpretation of quantum theory. The necessity of introducing many worlds is explained by analyzing a neutron interference experiment. The concept of the “measure of existence of a world” is introduced and some difficulties with the issue of probability in the framework of the MWI are resolved.

The articles in this volume explore the teachings on happiness by a range of thinkers from antiquity through Spinoza, most of whom held human happiness to comprise intellectual knowledge of that which is Good in itself, namely God. These thinkers were from Greek pagan, Muslim, Jewish, and Christian backgrounds and wrote their works in Greek, Arabic, Hebrew, and Latin. Still, they shared similar philosophical views of what constitutes the Highest Good, and of the intellectual activities to be undertaken in pursuit (...) of that Good. Yet, they differed, often greatly, in the role they assigned to deeds and practical activities in the pursuit of this happiness. These differences were, at times, not only along religious lines, but also along political and ethical lines. Other differences treated the relationship between the body and intellectual happiness and the various ways in which bodily health and well-being can contribute to intellectual health and true happiness.

Older adults process emotional speech differently than young adults, relying less on prosody (tone) relative to semantics (words). This study aimed to elucidate the mechanisms underlying these age-related differences via an emotional speech-in-noise test. A sample of 51 young and 47 older adults rated spoken sentences with emotional content on both prosody and semantics, presented on the background of wideband speech-spectrum noise (sensory interference) or on the background of multi-talker babble (sensory/cognitive interference). The presence of wideband noise eliminated age-related differences (...) in semantics but not in prosody when processing emotional speech. Conversely, the presence of babble resulted in the elimination of age-related differences across all measures. The results suggest that both sensory and cognitive-linguistic factors contribute to age-related changes in emotional speech processing. Because real world conditions typically involve noisy background, our results highlight the importance of testing under such conditions. (shrink)

Prominent thinkers such as Jurgen Habermas and Michael Sandel are warning that biomedical enhancements will undermine fundamental political values. Yet whether biomedical enhancements will undermine such values depends on how biomedical enhancements will function, how they will be administered and to whom. Since only few enhancements are obtainable, it is difficult to tell whether these predictions are sound. Nevertheless, such warnings are extremely valuable. As a society we must, at the very least, be aware of developments that could have harmful (...) consequences. Indeed, if important values were to be jeopardized, we should take appropriate measures to protect them. This paper focuses on four central values: solidarity, personal responsibility, equality and autonomy. It delineates the conditions under which biomedical enhancements would undermine these values. It also details the circumstances under which these values would be unaffected by enhancements as well as those under which they would be promoted. Specifying these conditions is valuable; it would enable society to prepare appropriate ethical guidelines and policy responses in advance. (shrink)

Following participation in Dr. Yair Caspi’s “Psychology in Judaism” workshop, the writers contemplate whether the teaching of Caspi’s model in academic settings could become simultaneously a fresh addition to interdisciplinary approaches to the teaching of Judaism in Israeli Academic life, and an academic addition to the contemporary trend to Jewish renewal in Israeli society. The model is based on weekly facilitated workshops in which participants both reflect on and discuss their lives and also explore unique interpretations of Jewish texts and (...) ideas, constantly seeking the borderline where their lives inform the text and vice versa. The process leads to the re-enchantment of ancient Jewish concepts, the reinvention of the Jewish religious experience in a contemporary paradigm and idiom, and the possibility of deep transformative insight.

In this introductory statement, given at the beginning of the Aboagora symposium in Turku in August 2011, Yehuda Elkana highlights the need, in accordance with the title of the conference, to rethink rather than unthink the Enlightenment. Indeed, the Enlightenment remained an unfinished project, but one should never forget that this era formed the basis for the greatest and most important creation of knowledge in all areas for 300 years. Over the last 100 or more years, however, cracks have (...) started to appear in this edifice, Elkana argues: researchers have started to realise that one cannot really distinguish the rational from the irrational and that being contextual does not necessarily mean being relativist.

“All Things Are Possible” is a 1920 English translation of the 1905 work by the Ukrainian/Russian existentialist philosopher Shestov. It draws on the aphoristic style of Nietzsche and deals with as diverse issues as science, rationalism and religion. This edition also includes an interesting foreword by D. H. Lawrence. Highly recommended for those with an interest in philosophy, and particularly existentialism. Contents include: “Lev Shestov”, “Note”, “Foreword”, “Zu Fragmentarish Ist Welt Und Leben”, and “Nur Für Schwindelfreie”. Many vintage books such (...) as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with a specially-commissioned new biography of the author. (shrink)

The main focus of the book is the presentation of the 'inertial' view of population growth. This view provides a rather simple model for complex population dynamics, and is achieved at the level of the single species without invoking species interactions. An important part of this account is the maternal effect. Investment of mothers in the quality of their daughters makes the rate of reproduction of the current generation depend not only on the current environment, but also on the environment (...) experienced by the previous generation.

PREFACE This volume is a sequel to yet independent of our Paranoia: A Study in Diagnosis, Reidel, Dordrecht and Boston, 1976. Whereas our first book centered on diagnosis, this centers on treatment. In our first volume, all discussions of nosology (theory of illness) and of treatment was ancillary to our discussion of diagnosis; similarly all discussion of this volume dealing with nosology - there is very little on diagnosis here - is ancillary to our discussion of psychotherapy. It is still (...) our profoundest conviction that to speak of treatment without diagnosis is meaningless, if not irresponsible, since otherwise one does not know what one is talking about. Hence, our present study, though it centers on theories of treatment, links psychotherapy with psychopathology. It is the rationale of psychotherapy which is of importance, and the rationale dwells in this link. We wish our present study to be self-contained and understood by readers who are not familiar with our first book - or with any specific literature. Our discussion of medicine in general, meaning the rationale of therapy in general, helps the uninitiated reader, as well as the initiated, we hope: it certainly has helped us. We did not see how else can we study a branch of medicine; we felt the need for some idea of how medicine is supposed to work. (shrink)

Although cognitive psychology and neuroscience have usurped the influential position once held by psychoanalysis, this volume seeks to reclaim the value of the unconscious as a methodological tool for the study of ancient texts by transforming our understanding of what it means, how it operates, and how it relates to textual hermeneutics.

The Zohar, the Cabbalistic ‘Bible’, has a special theory concerning magic. Magic, which for the Zohar is the essence of idolatry, is depicted there as identical in its form with Cabbalistic mystical theurgy, but directed not towards God but towards evil demons. This theory has been labeled in research Hermetic and Neo-Platonic, but only in general terms. This article makes a further step and finds a parallelism between a paragraph in the Zohar and a paragraph in On the Mysteries of (...) Iamblichus, the Neo-Platonic philosopher. The two paragraphs expound the above theory in similar terms, and also cite as their source a similar authority, namely eastern sages or Chaldaean prophets. This parallelism may establish a literary connection between the Zohar and Iamblichus, who may be related also in other respects. (shrink)

This paper examines the claim that the two final articles of Rav Kook’s book Ikvei Hatzon were written as a response to a lecture given by Hermann Cohen. It first reviews Cohen’s lecture showing that, regarding the concept of God, Cohen argues for the compatibility of Judaism and Kantianism in denying the dogmatic-mythological preoccupation with the existence of God in favor of understanding God as the basis of morality. Second, it analyzes Kook’s articles, demonstrating that he accepts the compatibility of (...) Judaism and Kantianism together with the denial of the dogmatic relation to God as a substance. Nevertheless, Kook is not satisfied with the critical view that denies the dogmatic relation to the substance altogether, since it formulates a merely negative relationship with God. Instead, he develops his concept of the Divine Ideals, which synthesizes the dogmatic preoccupation with substantiality and the critical denial of it. The Divine Ideals are the moral progression of man, through which man gradually becomes identical to God. Within the Divine Ideals, dogmatism becomes an emotional striving to be identical with God as a substance, while criticism is the intellectual negation of the possibility of such identity, which ensures that the process will continue indefinitely.

In this historical essay, we examine the reciprocal influences of philosophical doctrines and logic, their interrelations with language, and the place of mathematics in these developments.

Among the aims of the author in this wide-ranging article is to draw attention to the numerous formal sciences which so far have received little scrutiny, if at all, on the part of philosophers of mathematics and of science in general. By the formal sciences the author understands such mathematical disciplines as operations research, control theory, signal processing, cluster analysis, game theory, and so on. First, the author presents a long list of such formal sciences with a detailed discussion of (...) their subject matter and with extensive references to the pertinent literature. Turning to the nature of the formal sciences, the author states that “the formal sciences, though they arose in most cases out of engineering requirements, are sciences and can be pursued without reference to applications”. It is argued, through a wealth of examples, that in a great number of cases the formal sciences permit the attainment of provable certainty about actual parts of the world. As Franklin puts it, “knowledge in the formal sciences, with its proofs about network flows, proofs of computer program correctness, and the like, gives every appearance of having achieved the philosophers’ stone; a method of transmuting opinion about the base and contingent beings of this world into the necessary knowledge of pure reason.” Franklin clearly distinguishes between certainty and necessity: “ g¤g¤g what the mathematician in offering is not, in the first instance, absolute certainty in principle, but necessity. This is how his assertion differs from one made by a physicist. A proof offers a necessary connection between premises and conclusion. One may extract practical certainty from this g¤g¤g but this is a separate step.” Though Franklin explicitly states that there is a gap between necessity and certainty as one passes from mathematical reasoning to applications, the main thrust of the article consists in arguing that the gap is considerably smaller than generally claimed..
