World view issues have always been important to me and when I was young I looked into a lot. West  and East. Mainly I settled on the Oral and Written Law.  The Oral Law has no claim to divinity except in so far as it is accurate in its rigorous in its analysis of the verse of the Torah. In so far as it is objectively accurate to that degree it partakes of the holiness of Torah. But as a philosophical backing of Torah I have taken it as an axiom that Saadia Gaon and the Rambam knew what kind of world view was implicit in Torah.
And their approach while having some implications of mystic experience is not mystical but philosophical-and thus subject to the same kind of critique that any philosophical world view is subject to. So Torah has to stand up to critique. The way I have defended Torah is mainly by defending the Rambam's exposition of it in the Guide.

But as a rule I should say almost all world views I have encountered have serious problems with them. Some are obviously circular reasoning. Some are less obviously so.
