Thus, whatever phase of things human and divine you have apprehended, you will be wearied by the vast number of things to be answered and things to be learned. And in order that these manifold and mighty subjects may have free entertainment in your soul, you must remove therefrom all superfluous things.

You are only making unnecessary problems for yourself.
