There are a good number of books that deal with the philosophy of the Torah. They are not books of mysticism that use Torah as a jumping point for mysticism. And also they are not books about the השקפה or world view of Torah. They are actually books that deal with the philosophy of Torah. The main ones are from Saadia Gaon, Maimonides, Ibn Gavirol,, Crescas, Joseph Albo, Isaac Abrabanel, Judah Abrabanel. You almost never see them in yeshivas. In many yeshivas they are excluded on purpose. The reason I think is that there is great fear that some yeshiva student might pick one up and discover that they all claim the worldview of Torah is Monotheism, not pantheism. What yeshivas want their students to think is that no one ever thought about worldview issues of Torah until books came along that claimed the Torah's world view is pantheism. The ironic fact is that only Reform and conservative Jews have a belief system that is in accord with the Torah--Monotheism.
There was a controversy about the idea or desirability of learning Philosophy after the Rambam came about with the Guide for the Perplexed. The people opposed to this generally went with the more mystic kabbalist traditions. Each blamed the other for the perils of Jews in Spain.
The very fact that all philosophy [including all of the great Jewish philosophers from the Middle Ages] is excluded from all yeshivas shows where the weight of this debate came down on. That leaves only Secular and Reform Jews believing in Monotheism. You can see this fact in daily life. Often I hear some secular Jews tell a religious Jew that one must pray to God alone, not to any person. That I hear in answer to the statement of the religious Jew that the secular Jew ought to go to some tzadik and ask him for help.
