trade dominance was being usurped by coordinated Christian and Islamic forced-conversions, and torture, compelling Jewish scholars to understand nascent economic threats. These investigations triggered new ideas and intellectual exchange among Jewish and Islamic scholars in the areas of jurisprudence, mathematics, astronomy, logic and philosophy.

Contemporary scholars continue to debate who was Muslim and who was Jew—some "Islamic scholars" were "Jewish scholars" prior to forced conversion to Islam, some Jewish scholars willingly converted to Islam, such as

was a member of the latter. Hiwi is generally considered to be the very first "Jewish" philosopher to subject the Pentateuch to critical analysis. Hiwi is viewed by some scholars as an intellectually conflicted man torn between Judaism, Zoroastrianism, Gnostic Christianity, and Manichaean thought. Hiwi espoused the belief that miraculous acts, described in the Pentateuch, are simply examples of people using their skills of reasoning to undertake, and perform, seemingly miraculous acts. As examples of this position, he argued that the parting of the Red Sea was a natural phenomenon, and that Moses' claim to greatness lay merely in his ability to calculate the right moment for the crossing. He also emphasized that the Egyptian magicians were able to reproduce several of Moses' "miracles," proving that they could not have been so unique. According to scholars, Hiwi's gravest mistake was having the Pentateuch redacted to reflect his own views - then had those redacted texts, which became popular, distributed to children. Since his views contradicted the views of both Rabbanite and Karaite scholars, Hiwi was declared a heretic. In this context, however, we can also regard Hiwi, while flawed, as the very first critical biblical commentator; zealous rationalistic views of Hiwi parallel those of

Sa'adya Gaon denounced Hiwi as an extreme rationalist, a "Mulhidun", or atheist/deviator. Abraham Ibn Daud described HIwi as a sectarian who "denied the Torah, yet used it to formulate a new Torah of his liking".

(d. 956). In his brief survey of Arabic translations of the Bible, al-Masʿūdī states that the Israelites rely for exegesis and translation of the Hebrew books—i.e., the Torah, Prophets, and Psalms, twenty-four books in all, he says—on a number of Israelites whom they praise highly, almost all of whom he has met in person. He mentions Abū ʾl-Kathīr as one of them, and also Saadia ("Saʿīd ibn Yaʿqūb al-Fayyūmī"). Regardless of what we do not know, Saadia traveled to Tiberias (home of the learned scribes and exegetes) to learn and he chose Abū 'l-Kathīr Yaḥyā ibn Zakariyyāʾ al-Katib al-Tabariya. The extent of Abū ʾl-Kathīr's influence on Saadia's thought cannot be established, however. Abū ʾl-Kathīr's profession is also unclear. al-Masʿūdī calls him a ''kātib'', which has been variously interpreted as secretary, government official, (biblical) scribe, Masorete, and book copyist. For lack of further information, some scholars have tried to identify Abū ʾl-Kathīr with the Hebrew grammarian Abū ʿAlī Judah ben ʿAllān, likewise of Tiberias, who seems to have been a Karaite Jew. However, al-Masūdī unequivocally describes Abu ʾl-Kathīr (as well as his student Saadia) as an ashmaʿthī (Rabbanite). In "Book of the Articles of Faith and Doctrines of Dogma" Saadia declares the rationality of the Jewish religion with the caveat that reason must capitulate wherever it contradicts tradition. Dogma takes precedence over reason. Saadia closely followed the rules of the

discovered, in Imperial Library of St. Petersburg, fifteen of the twenty chapters of David's philosophical work entitled ''Ishrun Maḳalat'' (Twenty Chapters) of which 15 survive. One of the oldest surviving witnesses to early Kalām, it begins with epistemological investigations, turns to proofs of the creation of the world and the subsequent existence of a Creator, discusses the unity of the Creator (including the divine attributes), and concludes with theodicy (humanity and revelation) and a refutation of other religions (mostly lost). In 915 CE, Sa'adya Gaon left for Palestine, where, according to al-Masʿūdī (Tanbīh, 113), he perfected his education at the feet of Abū 'l-Kathīr Yaḥyā ibn Zakariyyāʾ al-Katib al-Tabari (d. 320/932). The latter is also mentioned by Ibn Ḥazm in his K. al-Fiṣlal wa 'l-niḥal, iii, 171, as being, together with Dāwūd ibn Marwān al-Muqammiṣ and Sa'adya himself, one of the mutakallimūn of the Jews. Since al-Muqammiṣ made few references to specifically Jewish issues and very little of his work was translated from Arabic into Hebrew, he was largely forgotten by Jewish tradition. Nonetheless, he had a significant impact on subsequent Jewish philosophical followers of the Kalām, such as Saʿadya Gaon.

Abu'l-Barakāt al-Baghdādī Abu'l-Barakāt Hibat Allah ibn Malkā al-Baghdādī ( ar, أبو البركات هبة الله بن ملكا البغدادي; c. 1080 – 1164 or 1165 CE) was an Islamic philosopher, physician and physicist of Jewish descent from Baghdad, Iraq. ...
, known as ''Hibat Allah'', was a Jewish philosopher and physicist and father-in-law of Maimonides who converted to Islam in his twilight years - once head of the Baghdad Yeshiva and considered the leading philosopher of Iraq.

Some suggest it was a reaction to a social slight inflicted upon him because he was a Jew, while others suggest he was forcibly converted at the edge of a sword (which prompted Maimonides to comment upon

). Despite his conversion to Islam, his works continued to be studied at the Jewish Baghdad Academy, a well-known academy, into the thirteenth century. He was a follower of Avicenna's teaching, who proposed an explanation of the acceleration of falling bodies by the accumulation of successive increments of power with successive increments of velocity. His writings include ''Kitāb al-Muʿtabar'' ("The Book of What Has Been Established by Personal Reflection"); a philosophical commentary on the Kohelet, written in Arabic using Hebrew aleph bet; and the treatise "On the Reason Why the Stars Are Visible at Night and Hidden in Daytime." According to Hibat Allah, ''Kitāb al-Muʿtabar'' consists in the main of critical remarks jotted down by him over the years while reading philosophical text, and published at the insistence of his friends, in the form of a philosophical work.

Moreover, it is the duty of every thinking Jew to become acquainted with the harmony existing between the fundamental doctrines of Judaism and those of philosophy, and, wherever they seem to contradict one another, to seek a mode of reconciling them".

Samuel ben Ali was an anti-Maimonidean operating in Babylon to undermine the works of Maimonides and those of Maimonides' patrons (the Al-Constantini family from North Africa). To illustrate the reach of the Maimonidean Controversy, Samuel ben Ali, the chief opponent of Maimonides in the East, was excommunicated by Daud Ibn Hodaya al Daudi (Exilarch of Mosul). Maimonides' attacks on Samuel ben Ali may not have been entirely altruistic given the position of Maimonides' in-laws in competing Yeshivas. In Western Europe, the controversy was halted by the burning of Maimonides' works by Christian Dominicans in 1232.

, translator of Maimonides. Due to these family ties Anatoli was introduced to the philosophy of Maimonides, the study of which was such a great revelation to him that he, in later days, referred to it as the beginning of his intelligent and true comprehension of the Scriptures, while he frequently alluded to Ibn Tibbon as one of the two masters who had instructed and inspired him. Anatoli wrote the ''Malmad'' exhibiting his broad knowledge of classic Jewish exegetes, as well as Plato, Aristotle, Averroes, and the Vulgate, as well as with a large number of Christian institutions, some of which he ventures to criticize, such as celibacy and monastic castigation, as well as certain heretics and he repeatedly appeals to his readers for a broader cultivation of the classic languages and the non-Jewish branches of learning. To Anatoli all men are, in truth, formed in the image of God, although the Jews stand under a particular obligation to further the true cognition of God simply by reason of their election, "the Greeks had chosen wisdom as their pursuit; the Romans, power; and the Jews, religiousness"


Hillel ben Samuel

Firstly,
Hillel ben Samuel Hillel ben Samuel (c. 1220 – Forlì, c. 1295) was an Italian physician, philosopher, and Talmudist. He was the grandson of the Talmudic scholar Eliezer ben Samuel of Verona. Life He spent his youth at Barcelona, where he studied the Talmud a ...
's importance in the history of medieval Jewish philosophy lies in his attempt to deal, systematically, with the question of the immortality of the soul. Secondly, Hillel played a major role in the controversies of 1289–90 concerning the philosophical works of Maimonides. Thirdly, Hillel was the first devotee of Jewish learning and Philosophy in Italy, bringing a close to a period of relative ignorance of Hakira in Verona (Italy). And finally, Hillel is one of the early Latin translators of "the wise men of the nations" (non-Jewish scholars). Defending Maimonides, Hillel addressed a letter to his friend Maestro Gaio asking him to use his influence with the Jews of Rome against Maimonides' opponents (Solomon Petit). He also advanced the bold idea of gathering together Maimonides' defenders and opponents in Alexandria, in order to bring the controversy before a court of Babylonian rabbis, whose decision would be binding on both factions. Hillel was certain the verdict would favor Maimonides. Hillel wrote a commentary on the 25 propositions appearing at the beginning of the second part of the Guide of the Perplexed, and three philosophical treatises, which were appended to Tagmulei ha-Nefesh: the first on knowledge and free will; the second on the question of why mortality resulted from the sin of Adam; the third on whether or not the belief in the fallen angels is a true belief.

whose family fled Spain to Narbonne. Ibn Falaquera lived an ascetic live of solitude. Ibn Falaquera's two leading philosophic authorities were Averroes and Maimonides. Ibn Falaquera defended the ''"Guide for the Perplexed"'' against attacks of anti-Maimonideans. He knew the works of the Islamic philosophers better than any Jewish scholar of his time, and made many of them available to other Jewish scholars – often without attribution (''Reshit Hokhmah''). Ibn Falaquera did not hesitate to modify Islamic philosophic texts when it suited his purposes. For example, Ibn Falaquera turned Alfarabi's account of the origin of philosophic religion into a discussion of the origin of the "virtuous city". Ibn Falaquera's other works include, but are not limited to Iggeret Hanhagat ha-Guf we ha-Nefesh, a treatise in verse on the control of the body and the soul. * ''Iggeret ha-Wikkuaḥ'', a dialogue between a religious Jew and a Jewish philosopher on the harmony of philosophy and religion. * ''Reshit Ḥokmah'', treating of moral duties, of the sciences, and of the necessity of studying philosophy. * ''Sefer ha-Ma'alot'', on different degrees of human perfection. * ''Moreh ha-Moreh'', commentary on the philosophical part of Maimonides' "Guide for the Perplexed".


Joseph ben Abba Mari ibn Kaspi

Ibn Kaspi was a fierce advocate of Maimonides to such an extent that he left for Egypt in 1314 in order to hear explanations on the latter's Guide of the Perplexed from Maimonides' grandchildren. When he heard that the Guide of the Perplexed was being studied in the Muslim philosophical schools of Fez, he left for that town (in 1332) in order to observe their method of study. Ibn Kaspi began writing when he was 17 years old on topics which included logic, linguistics, ethics, theology, biblical exegesis, and super-commentaries to Abraham Ibn Ezra and Maimonides. Philosophic systems he followed were Aristotle's and Averroes'. He defines his aim as "not to be a fool who believes in everything, but only in that which can be verified by proof...and not to be of the second unthinking category which disbelieves from the start of its inquiry," since "certain things must be accepted by tradition, because they cannot be proven." Scholars continue to debate whether ibn Kaspi was a heretic or one of Judaisms most illustrious scholars.

Albo rejects the assumption that

is essential in belief in God. Albo freely criticizes Maimonides' thirteen principles of belief and Crescas' six principles. According to Albo, "belief in the Messiah is only a 'twig' unnecessary to the soundness of the trunk"; not essential to Judaism. Nor is it true, according to Albo, that every law is binding. Although every ordinance has the power of conferring happiness in its observance, it is not true that every law must be observed, or that through the neglect of a part of the law, a Jew would violate the divine covenant or be damned. Contemporary Orthodox Jews, however, vehemently disagree with Albo's position believing that all Jews are divinely obligated to fulfill every applicable commandment.

Leone Ebreo

Judah Leon Abravanel Judah Leon Abravanel or Abrabanel () (c. 1460 Lisbon – c. 1530 ? Naples?), otherwise known by the pen name of Leo the Hebrew (in Latin: ''Leo Hebraeus''; in Portuguese: ''Leão Hebreu''; in Italian: ''Leone Ebreo''; in Spanish: ''León Hebreo' ...
was a Portuguese physician, poet and philosopher. His work ''Dialoghi d'amore'' ("Dialogues of Love"), written in Italian, was one of the most important philosophical works of his time. In an attempt to circumvent a plot, hatched by local Catholic Bishops to kidnap his son, Judah sent his son from Castile, to Portugal with a nurse, but by order of the king, the son was seized and baptized. This was a devastating insult to Judah and his family, and was a source of bitterness throughout Judah's life and the topic of his writings years later; especially since this was not the first time the Abravanel Family was subjected to such embarrassment at the hands of the Catholic Church. Judah's ''Dialoghi'' is regarded as the finest of Humanistic Period works. His neoplatonism is derived from the Hispanic Jewish community, especially the works of
Ibn Gabirol Solomon ibn Gabirol or Solomon ben Judah ( he, ר׳ שְׁלֹמֹה בֶּן יְהוּדָה אִבְּן גָּבִּירוֹל, Shlomo Ben Yehuda ibn Gabirol, ; ar, أبو أيوب سليمان بن يحيى بن جبيرول, ’Abū ’Ayy ...
. Platonic notions of reaching towards a nearly impossible ideal of beauty, wisdom, and perfection encompass the whole of his work. In ''Dialoghi d'amore'', Judah defines love in philosophical terms. He structures his three dialogues as a conversation between two abstract "characters": Philo, representing love or appetite, and Sophia, representing science or wisdom, Philo+Sophia (philosophia).

"Book of our Tradition" does not refer to mysticism of any kind - it chronicles "our tradition of scholarship and study" in two Babylonian Academies, through the Geonim, into Talmudic Yeshivas of Spain. In Talmudic times there was a mystic tradition in Judaism, known as ''Maaseh Bereshith'' (the work of creation) and ''Maaseh Merkavah'' (the work of the chariot); Maimonides interprets these texts as referring to Aristotelian physics and metaphysics as interpreted in the light of Torah. In the 13th century, however, a mystical-esoteric system emerged which became known as "the

''. Eli'ezer del Medigo, of Rome, received the surname "Del Medigo" after studying medicine. The name was later changed from ''Del Medigo'' to ''Ha-rofeh''. He was the father and teacher of a long line of rationalist philosophers and scholars. Non-Jewish students of Delmedigo classified him as an "Averroist", however, he saw himself as a follower of Maimonides. Scholastic association of Maimonides and Ibn Rushd would have been a natural one; Maimonides, towards the end of his life, was impressed with the Ibn Rushd commentaries and recommended them to his students. The followers of Maimonides (Maimonideans) had therefore been, for several generations before Delmedigo, the leading users, translators and disseminators of the works of Ibn Rushd in Jewish circles, and advocates for Ibn Rushd even after Islamic rejection of his radical views. Maimonideans regarded Maimonides and Ibn Rushd as following the same general line. In his book, Delmedigo portrays himself as defender of Maimonidean Judaism, and — like many Maimonideans — he emphasized the rationality of Jewish tradition.

Seventeenth-century Jewish philosophy

With expulsion from Spain came the dissemination of Jewish philosophical investigation throughout the Mediterranean Basin, Northern Europe and the Western Hemisphere. The center-of-mass of Rationalism shifted to France, Italy, Germany, Crete, Sicily and Netherlands. Expulsion from Spain and the coordinated pogroms of Europe resulted in the cross-pollination of variations on Rationalism incubated within diverse communities. This period is also marked by the intellectual exchange among leaders of the Christian Reformation and Jewish scholars. Of particular note is the line of Rationalists who migrated out of Germany, and present-day Italy into Crete, and other areas of the

This development, the culminating level of the Jewish mystical tradition, in this way bridges philosophy and mysticism, by expressing the transcendent in human terms.

's pragmatist philosophy. Dewey's naturalism combined atheist beliefs with religious terminology in order to construct a philosophy for those who had lost faith in traditional Judaism. In agreement with the classical medieval Jewish thinkers, Kaplan affirmed that haShem is not personal, and that all anthropomorphic descriptions of haShem are, at best, imperfect metaphors. Kaplan's theology went beyond this to claim that haShem is the sum of all natural processes that allow man to become self-fulfilled. Kaplan wrote that "to believe in haShem means to take for granted that it is man's destiny to rise above the brute and to eliminate all forms of violence and exploitation from human society."


Process theology

. Process philosophy suggests that fundamental elements of the universe are occasions of experience. According to this notion, what people commonly think of as concrete objects are actually successions of these occasions of experience. Occasions of experience can be collected into groupings; something complex such as a human being is thus a grouping of many smaller occasions of experience. In this view, everything in the universe is characterized by experience (not to be confused with consciousness); there is no mind-body duality under this system, because "mind" is simply seen as a very developed kind of experiencing entity. Intrinsic to this worldview is the notion that all experiences are influenced by prior experiences, and will influence all future experiences. This process of influencing is never deterministic; an occasion of experience consists of a process of comprehending other experiences, and then reacting to it. This is the "process" in "process philosophy". Process philosophy gives God a special place in the universe of occasions of experience. God encompasses all the other occasions of experience but also transcends them; thus process philosophy is a form of

wrote of the search for truth as "one of the strongest motives for scientific discovery." Still, he describes in ''Objective Knowledge'' (1972) early concerns about the much-criticized notion of truth as correspondence. Then came the semantic theory of truth formulated by the logician Alfred Tarski and published in 1933. Popper writes of learning in 1935 of the consequences of Tarski's theory, to his intense joy.
