After all people smart enough have already done the job of telling us the basic השקפה thought structure of the Torah--the Rambam and Saadia Gaon. And there is no book on השקפה today that agrees with anything they wrote. In the religious world, no one dares touch the Guide For the Perplexed of the Rambam or the אמונות ודעות of Saadia Gaon because the world view of the religious world is in fact directly opposed to everything the Rambam wrote in the Guide and Saadia Gaon.
So who do you trust to have a true and clear idea of what the Torah says? The Rambam or them?
And it is not as if the Rambam is hard to understand. The trouble is that he is infinitely easy to understand. The religious just don't like what he has to say.
