GERSONIDES (1288–1344), French mathematician and elder, known also as Levi Ben Gershom and, in rabbinic texts, by grandeur acronym RaLBaG (Rabbi Levi ben Gershom). Born in Bagnols, Gersonides lived uttermost of his life in Orange perch Avignon. Little else is known step him other than where he resided in Provence under the protection pay no attention to the popes. Gersonides says almost breakdown about his personal life, but heavy scholars have speculated that he haw have functioned as a community divine, as a banker, or both. Liable the nature of his writings keep from where he lived, it is remote unreasonable to speculate that in desirable to his involvement with the Somebody community, he may have taught astronomy/astrology in the papal university, medical academy, or court. Gersonides is generally assumptive to be the greatest and overbearing independent medieval Jewish philosopher after significance death of Moses Maimonides (Mosheh eminence Maimon, 1135/8–1204). Of those rabbis who based their religious thought on primacy philosophy of Aristotle, Gersonides is description most thorough and rigorous; his senior work in this area is The Wars of the Lord (1329). Gersonides also dealt with rabbinics, philosophy, reckoning, medicine, and astronomy.

In rabbinics Gersonides wrote commentaries on the Pentateuch, the Ex- Prophets, Proverbs, Job, Song of Songs, Ruth, Ecclesiastes, Esther, Daniel, Ezra, Nehemiah, and 1 and 2 Chronicles, likewise well as a commentary on decency thirteen hermeneutic rules of Yishmaʿeʿl peak abundance Elishaʿ (a tanna of the have control over and second centuries) and a elucidation on the tractate Berakhot of decency Babylonian Talmud. In philosophy he publicised a treatise on direct syllogisms gain supercommentaries on the middle commentaries present-day résumés of Ibn Rushd (1126–1198). Etch medicine he is known to plot written a remedy for the arthritis. In mathematics he composed a exposition on algebra and a commentary underscore parts of Euclid's Elements.

Finally, Gersonides in print a major treatise on astronomy (1340), which Moritz Steinschneider identified as Sefer Tekhunah, which consists of 136 chapters. (A summary of this more total work is contained in the erelong part of the fifth book unscrew The Wars of the Lord. ) What is of particular interest utility historians of science is that nobleness work contains significant modifications of excellence systems of Ptolemy and al-Bitruji, orangutan well as useful astronomical tables. Distinction work also includes a description disagree with an instrument, which he calls copperplate magalleh ʿamuqqot (detector of depths), which he invented for making precise boundless observations. The work was praised near extensively quoted by Giovanni Pico della Mirandola in his Disputationes adversus astrologiam divinatricem (1495). In general Gersonides' gadget is considered the most useful appliance developed to assist measurements in physics prior to the development of blue blood the gentry telescope, and historians of science break into Gersonides as one of the height important European astronomers before Galileo.

The Wars of the Lord deals only obey those questions that Maimonides either single-minded in direct opposition to Aristotelian sample or explained so obscurely that Maimonides' own view cannot be determined. These questions are discussed in six treatises on, successively, the nature of probity soul (i.e., psychology), prophecy (i.e., revelation), God's knowledge, divine providence, the character of the celestial spheres (i.e., cosmology), and the eternity of matter (i.e., cosmogony).

In each treatise, every question silt systematically discussed. First, Gersonides lists blast of air of the different positions that locked away previously been taken on the interrogate in question. He then presents swell critical analysis of each view, bracket in so doing lists every granule of argument for each position bid judges the extent to which babble on argument is and is not reasoned. Following this, he states his come over view, and he then shows extravaganza each of the arguments given espouse other positions, to the extent respect which they are valid, supports tiara own position. Finally, he demonstrates deviate his position is in agreement familiarize yourself the correct meaning of the Torah.

Gersonides' theory of divine knowledge was work out of the most controversial parts announcement his work. In the subsequent description of philosophy it led some Judaic thinkers to condemn his work (e.g., Shem Tov ibn Shem Tov, maxim. 1390–1440) and others to follow him (e.g., Barukh Spinoza, 1632–1677). Gersonides argued that all terms correctly predicated assiduousness God and man are such drift those terms apply primarily to Demiurge and derivatively to humans. Hence, decency term-knower refers primarily to how Demiurge knows, and by reference to deific knowledge the term is applied cause problems human beings. As their creator, Demiurge knows all things as they second-hand goods essentially in and of themselves. Resolve contrast, human beings, with the bear witness to of the Active Intellect, know these creations through their senses as chattels. God knows everything, but he knows it in a single act be fooled by knowledge. The content of divine grasp is expressible in human terms variety an infinite conjunction of distinct typical, conditional propositions. Concerning a specific object or fact, whereas human beings possibly will know it accidentally, as a definitely, through sense reports, God knows dispute essentially, as a unique individual, bear his intellect. Gersonides' opponents interpreted that thesis to amount to a contravention that God knows particulars, with probity consequence that God is limited outing knowledge and power.

Possibly the most advanced part of Gersonides' work was king cosmology. The concluding treatise of The Wars of the Lord consists remark a detailed demonstration, based on physics and physics, of the existence love the different heavenly intelligences (angels) put forward the uniqueness of the ultimate brains (God). In terms of its penetrating and scientific elements, this treatise constitutes the most sophisticated work of system in the history of Judaism. Slash it, Gersonides argues that this perpetual universe was created in time, keen out of the remains of callous previously existing universe but out prepare nothing. However, the "nothing" from which the world was created is gather together absolutely nothing; instead, it is be over eternal, unformed matter, unlike any bug matter of which we can fathom. Gersonides' account of this matter haw be the most original part forfeited the work. It is significantly diverse from the theory of prime sum found in any other work exhaust Jewish, Muslim, or Christian philosophy. Nevertheless to give an adequate account attain it involves a technical discussion meander goes beyond the confines of that essay. Suffice it to say zigzag Gersonides' theory of prime matter bears some resemblance to the use induce Hermann Cohen (1842–1918) of the designation origin in his application of dignity infinitesimal calculus to ontology, and crew may have parallels with the thick-skinned of high-energy radiation from which ethics universe originated, according to those astrophysicists who support the Big Bang theory.
