2 issues arise.
Firstly, the monist assertion of only a physical world fails to recognize a metaphysical significance in the rules of inference and 'laws of logic'. Just as there are skew lines, parallel and perpendicular lines in space, there would seem to be just as many rules of inference which aren't inutitive nor dependent upon the ones we might recognize intuitively. Our ability to perceive their correlation with a physical world seems to imply a wider domain of logic beyond our mere understanding.
Secondly, although we may have a wealth of technology and advanced science of the physical world around us today, the philosophy has been pondered for millenia by minds as equally as fervant, possibly more honed and focused than our own. When we read Scripture, an amazing volume of God's Word is dedicated to the topic. Scripture also speaks of miracles in greater and lessor cases. To deny such miracles or confine them to misperception is as( or moreso) ignorant of clues to truth than the supposition that those who wrote such things in Scripture spoke from a lack of knowledge.
Matter rules all the same!
