The unvoiced assumption here is that the universe is fundamentally knowable through rational materialism.

Among the many things we've learned from science is that there are real phenomena that we cannot perceive. We use microscopes, telescopes, x-ray machines and other sensors of all kinds which create simulacra of the real phenomena which we can perceive.

Extend the analogy to our brains -- consider that there are literally thoughts we cannot think. Our brains tells us there are no thoughts we can't think, but our brains may be liars. Is there a way for our brains to grasp the literally incomprehensible?

It’s not hard philosophy but I recommend Letters to a Young Poet by Rainer Maria Rilke
