" On the topic of omniscience and free will, Jacobs writes that in the medieval period, three views were put forth: Maimonides, who wrote that God had foreknowledge and man is free ; Gersonides, who wrote that man is free and consequently God does not have complete knowledge, and Hasdai Crescas, who wrote in Or Adonai that God has complete foreknowledge and consequently God is not really free.

Unfortunately, there is no evidence that the findings had an impact on later generations of astronomers, even though Gersonides ' writings were translated and available.

You state that Gersonides calculated that the stars were 10 billion times farther away from Earth than what Ptolemy claimed, i. e. in the order of 100 light years.

The history of the problem dates back at least to Gersonides, who proved a special case of the conjecture in 1343 where x and y were restricted to be 2 or 3.

Men like Albalag, Palquera, Gersonides, Narboni, and others, were denounced by Abravanel as infidels and misleading guides for assuming a comparatively liberal standpoint in religio-philosophical questions.

Gersonides believed that astrology was real, and developed a naturalistic, non-supernatural explanation of how it works.

So Gersonides works out to 1. 012830 exp19 km.

The philosopher and astronomer Rabbi Abraham ibn Ezra ( c. 1140 ) established the symmetry of binomial coefficients, while a closed formula was obtained later by the talmudist and mathematician Levi ben Gerson ( better known as Gersonides ), in 1321.

Major Jewish philosophers include Solomon ibn Gabirol, Saadia Gaon, Judah Halevi, Maimonides, and Gersonides.

Jewish neo-Aristotelian philosophers, who are still influential today, include Maimonides, Samuel ben Judah ibn Tibbon, and Gersonides.

:" The view that God does not have foreknowledge of moral decisions which was advanced by ibn Daud and Gersonides ( Levi ben Gershom ) is not quite as isolated as Rabbi Bleich indicates, and it enjoys the support of two highly respected Achronim, Rabbi Yeshayahu Horowitz ( Shelah haKadosh ) and Rabbi Chaim ibn Attar ( Or haHayim haKadosh ).

It is claimed that this is also the view expressed by some classical Jewish authorities, such as Abraham ibn Daud, Abraham ibn Ezra, and Gersonides.

* Jewish Science is sometimes also used in reference to the secular scholarship of some Jews in the Middle Ages, such as Abraham bar Hiyya, ibn Ezra, Gersonides, Abraham Zacuto, etc.

Thus instead there was a summary of the views of the most important medieval Jewish commentators, such as Abraham ibn Ezra, Rashi, Ramban, Radak, Sforno and Ralbag ( Gersonides ).

This was the program of Jewish rationalist philosophers such as Saadia Gaon, Maimonides ( who was influenced by Ibn Sina aka Avicenna ), and Gersonides ( who was influenced by Ibn Roshd, aka Averroes ).

Key Jewish philosophers included Samuel Ibn Tibbon, Maimonides, and Gersonides, among many others.

: 6. creation and miracles, in respect to which Gersonides deviates widely from the position of Maimonides.

Three noted Jewish examples are that of the writings of Philo of Alexandria ( 1st century ), Maimonides ( 12th century ) and Gersonides ( 13th century ).

Crescas makes no concealment of his purpose to vindicate classical Jewish thinking against the rationalism of Maimonides and Gersonides.

( Here he sides with Maimonides against Gersonides.

Crescas rejects the theories of Maimonides and Gersonides on this point.

Some medieval philosophical rationalists, such as Maimonides and Gersonides held that not every statement in Genesis is meant literally.

Gersonides on Providence, Covenant, and the Chosen People.

Louis Jacobs writes that modern Jewish thinkers such as Levi Olan, echoing some classical Jewish writers such as the 14th-century Talmudist Gersonides have " thought of God as limited by His own nature so that while He is infinite in some respects he is finite in others ," referencing the idea, present in classical sources, that " there is a primal formless material co-existent with God from all eternity upon which God has to work and that God only knows the future in a general sense but not how individual men will exercise their choice.

Levi ben Gershon, better known by his Latinised name as Gersonides or the abbreviation of first letters as RaLBaG ( 1288 – 1344 ), philosopher, Talmudist, mathematician, astronomer / astrologer.

: 1. the doctrine of the soul, in which Gersonides defends the theory of impersonal reason as mediating between God and man, and explains the formation of the higher reason ( or acquired intellect, as it was called ) in humanity — his view being thoroughly realist and resembling that of Avicebron ;

Gersonides was also the author of commentaries on the Pentateuch, Joshua, Judges, I & II Samuel, I & II Kings, Proverbs, Job, Ecclesiastes, Song of Songs, Ruth, Esther, Daniel, and Chronicles.

In contrast to the theology held by other Jewish thinkers, Jewish theologian Louis Jacobs argues, Gersonides held that God does not have complete foreknowledge of human acts.

" Gersonides, bothered by the old question of how God's foreknowledge is compatible with human freedom, holds that what God knows beforehand is all the choices open to each individual.

Gersonides posits that people's souls are composed of two parts: a material, or human, intellect ; and an acquired, or agent, intellect.

For Gersonides, Seymour Feldman points out, " Man is immortal insofar as he attains the intellectual perfection that is open to him.

Gersonides wrote Maaseh Hoshev in 1321 dealing with arithmetical operations including extraction of square and cube roots, various algebraic identities, certain sums including sums of consecutive integers, squares, and cubes, binomial coefficients, and simple combinatorial identities.

Gersonides was also the earliest known mathematician to have used the technique of mathematical induction in a systematic and self-conscious fashion and anticipated Galileo ’ s error theory.

Gersonides is the only astronomer before modern times to have estimated correctly stellar distances.

Ne ' eman argued that after Gersonides reviewed Ptolemy's model with its epicycles he realized that it could be checked, by measuring the changes in the apparent brightnesses of Mars and looking for cyclical changes along the conjectured epicycles.

Gersonides concluded that the model was no good.
