Some Christians view reason as the enemy of faith. For this reason (pun intended), they reject philosophy. This philosophy (pun intended, again) is known as Christian anti-intellectualism. As you can hopefully already see, it is self-refuting. Nonetheless, some point to Colossians 2:8 to try and defend this odd philosophy. Only by ripping this verse out of context could you get an interpretation that would defend a self-refuting position.
