English to Arabic Other Religion

this expression is ambiguos and I have two differeent interpreation for it:

العالم المادي
or
العالم غير المألوف

here is the context:

It is not that the methods and institutions of science somehow compel us accept a material explanation of the phenomenal world, but, on the contrary, that we are forced by our a priori adherence to material causes to create an apparatus of investigation and a set of concepts that produce material explanations, no matter how counter-intuitive, no matter how mystifying to the uninitiated.
