Modern secular thought has its own dualism: It treats only the physical world as knowable and testable, while locking everything else - mind, spirit, morality, meaning - into the realm of private, subjective feelings. The so-called fact/value split.

Can reason be an idol? Certainly. The philosophy of rationalism puts human reason in the place of God as the source and standard of all truth.

An idol is not necessarily something concrete, like a golden calf. It can also be something abstract, like matter. Is matter part of the created order? Sure it is. So the philosophy of materialism qualifies as an idol in the biblical sense.

Schools ought to teach students to challenge secular ideologies masquerading as science in the classroom.
