Orthodox Jewish philosophy comprises the philosophical and theological teachings of Orthodox Judaism. Though Orthodox Judaism sees itself as the heir of traditional rabbinic Judaism, the present-day movement is thought to have first formed in the late 18th century, mainly in reaction to the Jewish emancipation and the growth of the Haskalah and Reform movements. Orthodox Jewish philosophy concerns itself with interpreting traditional Jewish sources, reconciling the Jewish faith with the changes in the modern world and the movement's relationships with the State of Israel and other Jewish denominations.
Specific philosophies developed by Orthodox Jewish thinkers include:
Torah Judaism, an ideological concept used to legitimize Jewish movements within the framework of Orthodox Jewish values.
Hasidism, focusing on the importance of prayer, joy and the attachment to Tzadikim and Rebbes
Musar (ethics), stressing the importance of the study of ethical texts
Religious Zionism, an ideology that insists on the integration between Zionism and observance of Jewish law
Torah im Derech Eretz, a school of thought advocating the combination of Jewish and secular education
Torah Umadda, similar to Torah I'm Derech Eretz, advocating a combination of Jewish an secular education
Da'as Torah, the position that the opinion rabbinic authorities are to be sought in various circumstances
Dirah Betachtonim, a midrashic concept popularized by Chabad thinkers, the making of a "dwelling place for God in the lower realms" is thought to be the purpose of creation
