an idiot with courage to step off the well trodden paths that we know lead to hell and curiosity to consider and explore paths that have not been well trodden yet
the Law makes many simple and clear prescriptions about how to evaluate these other pathways and science is the general category.
it doesn't take a genius to recognise what comports with the Law and what is a deviation away from it, but it takes courage to go outside of the village and discover what God left us to see in the wilderness as guideposts towards becoming an instrument of His Will.
Satan strews these wild places with temptations and delusions and the Law is simple enough that even an IQ 80, or even lower, does not preclude sufficient grasp of the Law to be able to find the Way. we were all made different and our gifts open up pathways that we are uniquely created to follow.
understanding the primary laws of God is a prerequisite though. one of the most important ones is that there is no gain where it is not mutual and universal. universality is even the very meaning of the word Catholic, literally, the meaning.
the well trodden paths are a good entry point to this, and you have to walk those first before you can find the further routes towards what you were uniquely created to pursue.
there is no conflict between the individual and the universal, where the two things coincide.
