Jewish philosophy in the context of Dialectic

This article covers the conversations between Jewish philosophy and Islamic philosophy, and mutual influence on each other in response to questions and challenges brought into wide circulation through Aristotelianism, Neo-platonism, and the Kalam, focusing especially on the period from 800–1400 CE.

Jewish eschatology is the area of Jewish theology concerned with events that will happen in the end of days and related concepts. This includes the ingathering of the exiled diaspora, the coming of the Jewish Messiah, the afterlife, and the resurrection of the dead. In Judaism, the end times are usually called the "end of days" (aḥarit ha-yamim, אחרית הימים), a phrase that appears several times in the Tanakh.

These beliefs have evolved over time, and according to some authors there is evidence of Jewish belief in a personal afterlife with reward or punishment referenced in the Torah.

Criticism of Christianity has a long history that stretches back to the initial formation of the religion in the Roman Empire. Critics have challenged Christian beliefs and teachings, as well as actions taken in the name of the faith, from the Crusades to modern terrorism. The arguments against Christianity include claims that it is a faith of violence, corruption, superstition, polytheism, homophobia, bigotry, pontification, abuses of women's rights, and sectarianism.

In the early years of Christianity, the Neoplatonic philosopher Porphyry emerged as one of the major critics with his book Against the Christians, along with other writers like Celsus and Julian. Porphyry argued that Christianity was based on false prophecies that had not yet materialized. Following the adoption of Christianity by the Roman Empire, dissenting religious voices were gradually suppressed by both governmental and ecclesiastical authorities. Christianity has faced significant theological criticism from thinkers of other Abrahamic religions, particularly including Judaism and Islam. Notably, Maimonides, the renowned rabbi, Jewish philosopher, and Torah scholar of the 12th century, argued that Christian practices and doctrines constituted idolatry and deviated from the strict monotheism (shituf) of Jewish and Muslim theologies. Similarly, Islamic scholars have critiqued Christian beliefs about the Trinity and the divinity of Jesus, viewing these concepts as incompatible with the concept of monotheism. These critiques reflect deep theological disagreements rooted in their shared scriptural traditions and divergent doctrinal interpretations. A millennium later, the Protestant Reformation led to a fundamental split in European Christianity and rekindled critical voices about the Christian faith, both internally and externally. In the 18th century, deist philosophers such as Voltaire and Jean-Jacques Rousseau were critical of Christianity as a revealed religion. With the Age of Enlightenment, Christianity was criticized by major thinkers and philosophers, such as David Hume, Thomas Paine, and the Baron d'Holbach. The central theme of these critiques sought to negate the historical accuracy of the Christian Bible and focused on the perceived corruption of Christian religious authorities. Other thinkers, like Immanuel Kant, offered critiques of traditional arguments for the existence of God, while professing to defend Christian theology on novel grounds.

Plotinus (/plɒˈtaɪnəs/; Ancient Greek: Πλωτῖνος, Plōtînos; c. 204/5 – 270 CE) was a hellenised Egyptian Platonist philosopher, born and raised in Roman Egypt. Plotinus is regarded by modern scholarship as the founder of Neoplatonism. His teacher was the self-taught philosopher Ammonius Saccas, who belonged to the Platonic tradition. Historians of the 19th century invented the term "neoplatonism" and applied it to refer to Plotinus and his philosophy, which was vastly influential during late antiquity, the Middle Ages, and the Renaissance. Much of the biographical information about Plotinus comes from Porphyry's preface to his edition of Plotinus' most notable literary work, The Enneads. In his metaphysical writings, Plotinus described three fundamental principles: the One, the Intellect, and the Soul. His works have inspired centuries of pagan, Jewish, Christian, Gnostic, and early Islamic metaphysicians and mystics, including developing precepts that influence mainstream theological concepts within religions, such as his work on duality of the One in two metaphysical states.

The Talmud (/ˈtɑːlmʊd, -məd, ˈtæl-/; Hebrew: תַּלְמוּד‎, romanized: Talmūḏ, 'study' or 'learning') is the central text of Rabbinic Judaism and second in authority only to the Hebrew Bible (Tanakh), the first five books of which form the Torah. It is a primary source of Jewish law (הֲלָכָה, Halakha) and Jewish theology. It consists of the part of the Oral Torah compiled in the Mishnah and its commentaries, the Gemara. It records the teachings, opinions and disagreements of thousands of rabbis and Torah scholars—collectively referred to as Chazal—on a variety of subjects, including Halakha, Jewish ethics, philosophy, customs, history, and folklore among other topics. Until the Haskalah in the 18th and 19th centuries, the Talmud was the centerpiece of Jewish culture in nearly all communities and foundational to "all Jewish thought and aspirations", serving also as "the guide for the daily life" of Jews.

"Talmud" is used interchangeably with "Gemara". The text is made up of 63 tractates, each covering one subject area. The language of the Talmud is Jewish Babylonian Aramaic. Talmudic tradition emerged and was compiled between the destruction of the Second Temple in 70 CE and the Arab conquest in the early seventh century. Traditionally, it is thought that the Talmud itself was compiled by Rav Ashi and Ravina II around 500 CE, although it is more likely that this happened in the middle of the sixth century.

Moses ben Maimon, commonly known as Maimonides and also referred to by the Hebrew acronym Rambam, was a Sephardic Jewish rabbi who is widely acknowledged as one of the most prolific and influential Torah scholars of the Middle Ages. Originally from Córdoba, where he was born on Passover Eve of 1135 or 1138, his family was exiled from Muslim-ruled Spain when they refused to convert to Islam shortly after the Almohad Caliphate conquered the Almoravid Caliphate in 1148. Over the course of the next two decades, Maimonides resided in Fez, Acre, Jerusalem, Alexandria, and Cairo before finally settling in Fustat between 1168 and 1171. During this period, he advanced his vocations and became renowned for his achievements as an astronomer, philosopher, and physician—even being appointed to serve as personal physician to Saladin of the Ayyubid Sultanate.

Most contemporary Jews as far as Iraq and Yemen greeted Maimonides' writings on halakha and Jewish ethics with acclaim and gratitude. Yet, while he rose to lead the Jewish community in Egypt, he also had vociferous critics, particularly in Spain. He continued to live in Fustat until his death in 1204 and is said to have been buried in Tiberias. Accordingly, the Tomb of Maimonides in Tiberias holds importance as a Jewish pilgrimage site.

Shituf (Hebrew: שִׁתּוּף; also transliterated as shittuf or schituf; literally "association") is a term used in Jewish sources for the worship of God in a manner which Judaism does not deem to be purely monotheistic. The term connotes a theology that is not outright polytheistic, but also should not be seen as purely monotheistic. The term is primarily used in reference to the Christian Trinity by Jewish legal authorities who wish to distinguish Christianity from full-blown polytheism. Though a Jew would be forbidden from maintaining a shituf theology, non-Jews would, in some form, be permitted such a theology without being regarded as idolaters by Jews. That said, whether Christianity is shituf or formal polytheism remains a debate in Jewish philosophy.

Shituf is first mentioned in the commentary of Tosafot on the Babylonian Talmud, in a passage concluding with a lenient ruling regarding non-Jews. Later authorities are divided between those who view Tosfot as permitting non-Jews to swear by the name of God even if they associate other deities with that name, and those who view Tosfot as permitting non-Jews to actually worship such deities. Though shituf is primarily used as a means of determining how to relate to Christians, it is applied to other religions as well. It is frequently used as a reason to justify interfaith dialogue with Christians.

The Jewish Golden Age in Spain began shortly after the Muslim conquest in the 8th century and lasted until the Christian Reconquista resulted in the expulsion of Jews by the 15th century. During this period, Jews living in what was collectively called al-Andalus (Muslim-ruled Spain and Portugal) experienced relative tolerance, prosperity, and socio-cultural integration within the broader Muslim society that had come to dominate the region. Owing to this environment, Jewish culture flourished and several Jews rose to prominence in scholarly and religious spheres, including Maimonides, Hasdai ben Shaprut, Shmuel ha-Nagid, Solomon ben Judah, and Judah ha-Levi. The Jewish community of al-Andalus also contributed greatly to the Muslim world's advancements in astronomy, medicine, and science.

Jews under Muslim authority in Spain and Portugal were designated as dhimmi (Arabic: ذمي)—a legally protected class of non-Muslim subjects—in exchange for paying jizya (جِزْيَة) and accepting certain restrictions. Although they still held a second-class status relative to Muslims, the dhimmi framework in al-Andalus gradually allowed for the development of stability and co-existence that was otherwise uncommon in Jewish history in Europe; Jews were able to occupy a variety of positions in government and diplomacy, medicine, and science, while also playing a key role in the Muslim world's transmission of classical knowledge to Christian Europe. Further, the Jewish Golden Age in Spain brought about remarkable achievements in Hebrew poetry, religious scholarship, grammar, and philosophy. Some historians, however, view this to be more of a myth.

Jewish literature includes works written by Jews on Jewish themes, literary works written in Jewish languages on various themes, and literary works in any language written by Jewish writers. Ancient Jewish literature includes Biblical literature and rabbinic literature. Medieval Jewish literature includes not only rabbinic literature but also ethical literature, philosophical literature, mystical literature, various other forms of prose including history and fiction, and various forms of poetry of both religious and secular varieties. The production of Jewish literature has flowered with the modern emergence of secular Jewish culture. Modern Jewish literature has included Yiddish literature, Judeo-Tat literature, Ladino literature, Hebrew literature (especially Israeli literature), and Jewish American literature.

Saʿadia ben Yosef Gaon or Said bin Yusuf al-Fayyumi (892–942) was a prominent rabbi, gaon, Jewish philosopher, and exegete who was active in the Abbasid Caliphate.

Saadia is the first important rabbinic figure to write extensively in Judeo-Arabic. Known for his works on Hebrew linguistics, Halakha, and Jewish philosophy, he was a student of the philosophical school known as "Jewish Kalam". In this capacity, his philosophical work entitled The Book of Beliefs and Opinions represents the first systematic attempt to integrate Jewish theology with components of ancient Greek philosophy. Saadia was also very active in opposition to Karaite Judaism in defense of Rabbinic Judaism.

Oliver Leaman (born 1950) is an American professor of philosophy and Zantker Professor of Judaic studies at the University of Kentucky, where he has been teaching since 2000. He specialized in the history of Islamic, Jewish, and Eastern philosophy. He received his Ph.D. from the University of Cambridge in 1979.

Chazal or Ḥazal (Hebrew: חז״ל) are the Jewish sages of the Mishnaic and Talmudic eras, spanning from the final 300 years of the Second Temple period until the 7th century, or c. 250 BCE – c. 625 CE. Their authority was mostly in the field of Halakha (Jewish law) and less regarding Jewish theology.

Rabbinic authority in Judaism relates to the theological and communal authority attributed to rabbis and their pronouncements in matters of Jewish law. The extent of rabbinic authority differs by various Jewish groups and denominations throughout history.

The origins of rabbinic authority in Judaism is understood as originally linked to the High Court of ancient Israel and Judah, known as the Sanhedrin. Scholars understand that the extent of rabbinic authority, historically, would have related to areas of Jewish civil, criminal, and ritual law, while rabbinic positions that relate to non-legal matters, such as Jewish philosophy would have been viewed as non-binding.

Mordecai Menahem Kaplan (June 11, 1881 – November 8, 1983) was an American Conservative rabbi, writer, Jewish educator, professor, theologian-philosopher, activist, and religious leader who founded the Reconstructionist movement of Judaism with his son-in-law, Rabbi Ira Eisenstein. He has been described as a "towering figure" in the recent history of Judaism for his influential work in adapting it to modern society, contending that Judaism should be a unifying and creative force by stressing the cultural and historical character of the religion as well as theological doctrine.

According to Jewish tradition, the Tomb of Maimonides (Hebrew: קבר הרמב"ם Kever ha-Rambam) is located in Tiberias, Israel. Although Maimonides, a Sephardic Jew, died in Fustat, Egypt, on 12 December 1204, it is believed that he was only briefly buried in Fustat before being reinterred in Tiberias. Owing to his recognition as a prominent Jewish philosopher, his tomb is one of Israel's most important Jewish pilgrimage sites and is also among Tiberias' most visited tourist attractions. The site also serves as the burial place of Yohanan ben Zakkai, a prominent Tanna of the Second Temple period; and Isaiah Horowitz, a prominent Jewish mystic of the 16th/17th century.

Pirkei Avot (Hebrew: פִּרְקֵי אָבוֹת, romanized: pirqē aḇoṯ, lit. 'Chapters of the [Fore]fathers'; also transliterated as Pirqei Avoth or Pirkei Avos or Pirke Aboth, also Abhoth), is a compilation of the Jewish theological and ethical teachings and maxims from Rabbinic Jewish tradition. It is part of didactic Jewish ethical literature. Because of its contents, the name is sometimes given as Ethics of the Fathers. Pirkei Avot consists of the Mishnaic minor tractate of Avot, the second-to-last tractate in the order of Nezikin in the Mishnah, plus one additional chapter. Avot is unique in that it is the only tractate of the Mishnah dealing solely with ethical and moral principles; there is relatively little Halakha (Jewish law) in Pirkei Avot.

In Judaism, angels (Hebrew: מַלְאָךְ, romanized: mal’āḵ, lit. 'messenger', plural: מַלְאָכִים mal’āḵīm) are supernatural beings that appear throughout the Tanakh (Hebrew Bible), Rabbinic literature, Jewish apocrypha, Christian pseudepigrapha, Jewish philosophy, Jewish mysticism, and traditional Jewish liturgy as agents of the God of Israel. They are categorized in different hierarchies. Their essence is often associated with fire. The Talmud describes their very essence as fire.
