Cover art for Rational Gaze lyrics by Meshuggah

This song is about relativism and how we humans will never be able to 'reach' absolute knowledge, as we are confined to our human way of thinking. In fact, the term 'absolute knowledge' is a human term, and we will never be able to sanely cross our 'thinking borders' to somehow understand what's beyond them. This I believe is what the lines "perspectives distorted, the ladder beyond our grasp, the twinheaded serpent forever hidden" point to.

I believe the lines "reality untouchable, transparent, invisible to our fixed, restricted fields of vision, Existence taken for granted absolute" definitely point towards relativism.

Did anyone read the book 'Zen And The Art Of Motorcycle Maintenance'? In it, the main character discovers a different way of understanding the world, a way of thinking which leads out of the 'human realm' of thinking. The more he tries to perceive this understanding, the more he slips away, eventually turning insane, at least in our eyes. I think this what concerns the lines "where's the true knowledge, where engines of the sane and insanity merge".

For those wondering what the hell I'm babbling about: try looking up the terms 'relativism', 'absolute knowledge', and 'sophism' in Wikipedia and things will hopefully become clearer. :)
