Some Christians seem to think the way to avoid being “conformed to this world” (Rom. 12:2) is by avoiding “worldly” ideas. A better strategy is to learn the skills to critically evaluate them. G. K. Chesterton argued that ideas are actually more dangerous to the person who has not studied them. Because he has no mental filter, a new idea will “fly to his head like wine to the head of a teetotaler.”
