Philo of Alexandria

Philo attempted to fuse and harmonize Greek Philosophy and Judaism via allegory which he learned from Jewish exegesis and the Stoics. Philo attempted to make his philosophy the means of defending and justifying Jewish religious truths. These truths he regarded as fixed and determinate, and philosophy was used as an aid to truth, and a means of arriving at it. To this end Philo chose from philosophical tenets of Greeks, refusing those that did not harmonize with Judaism such as Aristotle's doctrine of the eternity and indestructibility of the world.

Karaism

Karaites were the first Jewish Sect to subject Judaism to Mu'tazilah. Rejecting Talmud and Rabbinic tradition, Karaites took liberty to reinterpret Tanach as they saw fit. This meant abandoning foundational Jewish belief structures. Some scholars suggest that the major impetus for the formation of Karaism was a reaction to the rapid rise of Shi'a Islam, which recognized Judaism as a fellow monotheistic faith, but claimed that it detracted from monotheism by deferring to Rabbinic authority. Karaites absorbed certain aspects of Jewish sects such as Isawites (Shi'ism), Malikites (Sunnis) and Yudghanites (Sufis), who were influenced by East-Islamic scholarship yet deferred to Ash'ari

"Hiwi the Heretic"

According to Saadia Gaon, the Jewish community of Balkh
Balkh
Balkh , was an ancient city and centre of Zoroastrianism in what is now northern Afghanistan. Today it is a small town in the province of Balkh, about 20 kilometers northwest of the provincial capital, Mazar-e Sharif, and some south of the Amu Darya. It was one of the major cities of Khorasan...

 was a member of the latter. Hiwi is generally considered to be 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 Reed 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 Ibn al-Rawandi
Ibn al-Rawandi
Abu al-Hasan Ahmad ibn Yahya ibn Ishaq al-Rawandi , commonly known as Ibn al-Rawandi , was an early skeptic of Islam and a critic of religion in general.

.

Saadia Gaon wrote a polemic against Hiwi denouncing him 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".

("Beliefs and opinions") was originally called Kitab al-Amanat wal-l'tikadat ("Book of the Articles of Faith and Doctrines of Dogma"); it was the first systematic presentation and philosophic foundation of the dogmas of Judaism, completed at Sura Academy in 933 CE.

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 Mu'tazilah school of Abu Ali al-Jubba'i in composing his works. It was Saadia, who laid foundations for Jewish rationalist theology which built upon the work of Mu'tazilah, thereby shifting Rabbinic Judaism from mythical explanations of the Rabbis to reasoned explanations of the intellect.

Like the Ismailis, Nethanel al-Fayyumi argued that haShem sent different prophets to various nations of the world, containing legislations suited to the particular temperament of each individual nation. Ismaili doctrine holds that a single universal religious truth lies at the root of the different religions. Some Jews accepted this model of religious pluralism, leading them to view Prophet Mohammed as a legitimate prophet, though not Jewish, sent to preach to the Arabs, just as the Hebrew prophets had been sent to deliver their messages to Israel; others refused this notion in entirety. Nethanel's son Yakob ben Nethanel Ibn al-Fayyumi turned to Maimonides, asking urgently for counsel on how to deal with forced conversions to Islam and religious persecutions at the hand of Saladin

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".

Maimonides' attacks on Ibn al-Dastur 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. Avraham son of Rambam

 is generally regarded as a pioneer in the application of the Maimonidean Rationalism to the study of Jewish texts. He was the son-in-law of Samuel ibn Tibbon, 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 G-d, though the Jews stand under a particular obligation to further the true cognition of G-d 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'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 cetrtain 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.

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 their 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".

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 system he followed Aristotle 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.

, is important. He was also a student of philosophy, astronomy, mathematics, and especially of medicine, which he practiced for a number of years at Palma, in Majorca. Magen Avot deals with concepts such as the nature of haShem, the eternity of the Torah, the coming of the Messiah, and the Resurrection of the dead. Duran believed that Judaism has three dogmas only: the existence of haShem, the Torah's Divine origin, and Reward and Punishment; in this regard he was followed by Joseph Albo.

. He wrote Sefer ha-Ikkarim ("Book of Principles"), a classic work on the fundamentals of Judaism. Albo narrows the fundamental Jewish principles of faith from thirteen to three -
  • belief in the existence of haShem,
  • belief in revelation, and
  • belief in divine justice, as related to the idea of immortality.

Albo rejects the assumption that creation ex nihilo is essential in belief in haShem. 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. Though 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.

Don Isaac Abravanel

Isaac Abravanel, statesman, philosopher, Bible commentator, and financier who commented on Maimonides' thirteen principles in his Rosh Amanah. Isaac Abravanel was steeped in Rationalism by the Ibn Yahya family, who had a residence immediately adjacent to the Great Synagogue of Lisbon (also built by the Ibn Yahya Family). His most important work, Rosh Amanah ("The Pinnacle of Faith"), defends Maimonides' thirteen articles of belief against attacks of Hasdai Crescas and Yosef Albo. Rosh Amanah ends with the statement that "Maimonides compiled these articles merely in accordance with the fashion of other nations, which set up axioms or fundamental principles for their science".

Isaac Abravanel was born and raised in Lisbon; a student of the Rabbi of Lisbon, Yosef ben Shlomo Ibn Yahya. Rabbi Yosef was a poet, religious scholar, rebuilder of Ibn Yahya Synagogue of Calatayud, well versed in rabbinic literature and in the learning of his time, devoting his early years to the study of Jewish philosophy. The Ibn Yahya family were renowned physicians, philosophers and accomplished aides to the Portuguese Monarchy for centuries.

Isaac's grand-father, Samuel Abravanel, was forcibly converted to Christianity during the pogroms of 1391 and took the Spanish name "Juan Sanchez de Sevilla". Samuel fled Castile-Leon, Spain, in 1397 for Lisbon, Portugal, and reverted to Judaism - shedding his Converso

 was 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. 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).

Criticisms of Kabbalah

The word "Kabbalah" was used in medieval Jewish texts to mean "tradition", see Abraham Ibn Daud
Abraham ibn Daud
Abraham ibn Daud was a Spanish-Jewish astronomer, historian, and philosopher; born at Toledo, Spain about 1110; died, according to common report, a martyr about 1180. He is sometimes known by the abbreviation Rabad I or Ravad I. His mother belonged to a family famed for its learning...

's Sefer Ha-Qabbalah also known as the "Book of our Tradition". "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, an mystical-esoteric system emerged which became known as "the Kabbalah

In the 13th century, *Meir ben Simon of Narbonne wrote an epistle (included in Milhhemet Mitzvah) against early Kabbalists, singled out Sefer Bahir, rejecting the attribution of its authorship to the tanna R. Nehhunya ben ha-Kanah and describing some of its content as follow -
"... And we have heard that a book had already been written for them, which they call Bahir, that is 'bright' but no light shines through it. This book has come into our hands and we have found that they falsely attribute it to Rabbi Nehunya ben Haqqanah. haShem forbid! There is no truth in this... The language of the book and its whole content show that it is the work of someone who lacked command of either literary language or good style, and in many passages it contains words which are out and out heresy."

. 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.

With expulsion from Spain came the dissemination of Jewish Philosophical investigation throughout the Mediterranean Basin, Northern Europe and Western Hemisphere. The center-of-mass of Rationalism shifts to France, Italy, Germany, Crete, Sicily and Netherlands. Expulsion from Spain and the coordinated pogroms of Europe resulted in the cross-pollenation of variations on Rationalism incubated within diverse communities.

, "from my flesh I see HaShem", Shneur Zalman explained the inner meaning, or "soul", of the Jewish mystical tradition in intellectual form, by means of analogies drawn from the human realm. As explained and continued by the later leaders of Chabad, this enabled the human mind to grasp concepts of Godliness, and so enable the heart to feel the love and awe of HaShem, emphasised by all the founders of hasidism, in an internal way. This development, the culminating level of the Jewish mystical tradition, in this way bridges philosophy and mysticism, by expressing the transcendent in human terms.

 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 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 HaShem a special place in the universe of occasions of experience. HaShem encompasses all the other occasions of experience but also transcends them; thus process philosophy is a form of panentheism
