By Wolfson, Harry Austrin

После закрытия философских школ в Афинах в начале VI ст. огромное значение для философии приобрел постепенный перевод греческих трактатов на древнесирийский, арабский, иврит и латынь. После Саадии (882-942) и Маймонида (1135-1204) центр еврейской философии перемещается в неарабские страны -христианскую Испанию, в южную Францию и в Италию. В это время наиболее ярким примером взаимопроникновения греческой, арабской и еврейской традиций становятся работы Хасдая бен Авраама Крескаса (1340—1410). В них отражены наиболее общие философские достижения за период 500-летнего синкретического взаимопроникновения мусульманской и иудейской культур. Исследования Крескаса основаны на гипотетико-дедуктивном методе, называемом «пилпуль», являющемся в действительности применением научной процедуры к исследованию текстов, и указывающим на новизну и независимость разума в еврейских текстуальных исследованиях задолго до появления критического рационализма Декарта. Помимо этого, положения Крескаса по проблеме "естественного права" и свободы воли во всем величии предшествуют аналогичным положениям в философии Спинозы. Если консуться вклада Крескаса в науку, то он по истине бесценен: возможность бесконечности, пустого пространства и времени, зарождение понятия "инерции" - и все это в XIV веке... Предлагаемая работа Вольфсона, по форме, есть извлечение «света бога», заключенного в текстах Крескаса (труд "Or Adonai"), а по содержанию, исследование наиболее важных положений "Физики" Аристотеля и трактата «О небе». Используя работы аль-Газали, Авиценны и комментарии Аверроэса к Аристотелю, автор в своей книге проясняет малоизученные стороны взаимовлияния арабской и еврейской философии. Особое внимание Вольфсон сосредотачивает на одном из определяющих понятий в философии Крескаса – категории «осуществления». В первой части книги Вольфсон подробно останавливается на доказательствах 25 предложений Маймонида, суммирующих аристотелевский корпус. Третья часть книги представляет собой отдельное исследование положений Крескаса «О существовании и свойствах Бога». В четвертой главе философия Крескаса рассматривается как основа-предвестник «новой концепции вселенной» XVI века.

Get A Bayesian Analysis of QCD Sum Rules PDF

By Philipp Gubler

ISBN-10: 4431543171

ISBN-13: 9784431543176

The writer develops a singular research technique for QCD sum principles (QCDSR) by means of utilizing the utmost entropy procedure (MEM) to reach at an research with much less man made assumptions than formerly held. it is a first-time accomplishment within the box. during this thesis, a reformed MEM for QCDSR is formalized and is utilized to the sum ideas of numerous channels: the light-quark meson within the vector channel, the light-quark baryon channel with spin and isospin half, and several other quarkonium channels at either 0 and finite temperatures. This novel means of combining QCDSR with MEM is utilized to the learn of quarkonium in sizzling topic, that's a huge probe of the quark-gluon plasma at the moment being created in heavy-ion collision experiments at RHIC and LHC.
