How do we understand molecules or cells? Through microscopes with our sense of vision? We haven't avoided the subjective sense problem at all! Merely refined it. We _can_ see the molecular machinery of the cell, having the ability to augment our senses with technology, and what we see must account for human subjectivity in a myriad of ways.

Math is a more interesting case, in that regard, as it is more clearly divorced from sense data in the classic sense. Though with the nondual perspective being presented here in mind, thought and logic is often lumped in closer to being a kind of sense - I don't _think_, I _experience thoughts_. I'm not settled on the point, but that framework would allow us to say "math is a function of the way human brains sense logical resolutions among axioms".
