I actually think compartmentalization is good practice.

There's a famous saying in statistics, "all models are wrong, but some models are useful." JMG is swift to point out (following Kant) that models are all we have access to, and Plotinus would say Objective Truth only exists at the level of the Intellect (which we're two hops away from)! Here in the material world, we're merely the blind men and the elephant: any teaching we have access to can only encapsulate one small nugget of Truth, and it isn't possible even in theory to reconcile them all.

It is good to learn to use a tool when it's appropriate, but it must also be kept in mind that no tool can be universal!
