"But am I satisfied to know merely the structure of the rainb..." — Tanner Cook quote meaning

But am I satisfied to know merely the structure of the rainbow and how it came to be? Is that why I gaze upon it; with thoughts of refraction and wave frequency? Am I better off, now that I know this celestial arch isn’t divinely inspired – that there isn’t some meaningful purpose to it? Is that truly the answer I wanted when I asked myself where this spectacle came from? Do I stare up at the night sky because I search for the elements that comprise the star? Do we rationalize the tears that are shed at the birth of a child and the death of a loved-one? Do we ask ourselves why we dance? Do we contemplate that question before we allow the music to stir us? Do we allow it at all, or does it allow us? Not a single note, by itself, compels a couple to gracefully embrace, yet, this is how they would have us understand it - music, merely a series of connected notes and nothing more.
