The paper includes a series of letters exchanged between the author and the late Professor Feyerabend, concerning the best "method" for military intelligence, as a test case for the role of conceptual frameworks in philosophy of science. The letters deal with issues like: Is it possible to make an intelligence estimate without a conceptual framework? Does such a framework have any 'positive' role? If so, how should a conceptual framework in intelligence be built? What risks lurk within it? Is it (...) possible to indicate methods for intelligence estimates which are 'better' and more 'successful' than others? (shrink)

Talmon's treatment of nationalism varies in his different writings. This study will try to characterize his views as expressed in his final work, The Myth of the Nation and the Vision of Revolution. Through most of the book Talmon's preference for dealing with the vision of revolution, its prophets and bearers is very conspicuous. Their total devotion to restructuring and refashioning the whole world in accordance with the socialist ideology fascinated Talmon before it provoked him into analyzing it to death. (...) Nationalism, on the other hand, appears at best as a natural feeling of loyalty and at worst as a hateful, aggressive, and racist obsession. One of his outstanding interests in that book is in the internal debate among socialists about nationalism as a value and as a strategy, and in the tremendous prominence of Jews in this process. It is only towards the end of the book that Talmon presents his main thesis, the confrontation between the two totalitarian ideologies, Bolshevism and Fascism as deriving from socialism and nationalism, and embodying two kinds of determinism, economic and biological. Nationalism appears as an irrational phantasy, which had developed throughout the nineteenth century to its pivotal culmination in Nazism. This highly problematic thesis, though brilliantly expressed by captivating metaphors, should I think be explained and revised. (shrink)

Svensson argued that the concept of the weak value of an observable of a pre- and post-selected quantum system cannot be applied when the expectation value of the observable in the initial state vanishes. Svensson’s argument is analyzed and shown to be inconsistent using several examples.

Nefesh HaTzimtzum provides the single most comprehensive and accessible presentation of the teachings and worldview of the Vilna Gaon's primary student, Rabbi Chaim Volozhin. It is focused on Rabbi Chaim's magnum opus, Nefesh HaChaim, a work that has lain in almost total obscurity for nearly two centuries due to its deep Kabbalistic subject matter. Nefesh HaTzimtzum opens up the real depth of the ideas presented in Nefesh HaChaim together with all of Rabbi Chaim's related writings, making them accessible to the (...) public for the first time in any language. In addition to the complete English translation, Nefesh HaTzimtzum includes the full facing page Hebrew text of Nefesh HaChaim and many other writings by Rabbi Chaim, along with in-depth explanations, an informative historical overview, an easily consumable innovative presentation layout and a full index. After centuries of confusion, extensive clarification is provided of the central Kabbalistic concept of Tzimtzum, or the secret of how an infinite God occupies a finite world. Most importantly, it unequivocally demonstrates that the key Kabbalists, including the Vilna Gaon, Rabbi Chaim Volozhin and the Baal HaTanya, all unanimously agreed on the underlying principles of the concept of Tzimtzum and that contrary to widespread historical misunderstanding, there was no fundamental dispute about the philosophical principles of Judaism between the Hasidim and the Mitnagdim. Based on this Nefesh HaTzimtzum shows that both Nefesh HaChaim and Sefer HaTanya present the same methodology for serving God which is rooted in their identical understanding of the concept of Tzimtzum. Nefesh HaTzimtzum is published in two volumes which are sold separately. This volume contains the complete Hebrew text of Nefesh HaChaim which is brought to life by an illuminating translation and incisive commentary. It additionally provides extensive translated source material necessary to properly understand the basic text. The text is further complemented by an informative introduction which includes a historical overview. (shrink)

Mentoring Away the Glass Ceiling in Academia: A Cultured Critique describes how women of diverse backgrounds perceive their mentoring experiences or the lack of mentoring experiences in the academy. This book provides a space for envisioning strategies and practices to improve mentoring practices and the collegiate environment.

For a locally compact group G, we show that it is possible to present the class of continuous unitary representations of G as an elementary class of metric structures, in the sense of continuous logic. More precisely, we show how nondegenerate ∗-representations of a general ∗-algebra A (with some mild assumptions) can be viewed as an elementary class, in a many-sorted language, and use the correspondence between continuous unitary representations of G and nondegenerate ∗-representations of L1(G). We relate the notion (...) of ultraproduct of logical structures, under this presentation, with other notions of ultraproduct of representations appearing in the literature, and we characterize property (T) for G in terms of the definability of the sets of fixed points of L1 functions on G.
