the slow art of deleting everything that isn't the point.
means The process of improving something by removing flaws, impurities, or excess until only the better, purer version remains.
from From Latin 'finis' — an end, a limit, a boundary. The 'fine' inside 'refinement' is the same 'fine' that means both 'high quality' and 'a thing brought to its proper conclusion.' To 'refine' (via French 'raffiner', built on 're-' + 'fin') was literally to bring metal or sugar to its finest state by burning off the dross. The word carried that sense of purification through fire into the abstract: to refine a manner, a sentence, or an idea is to keep boiling away what isn't essential until you reach the bottom of it.
