Push it. Examine all things intensely and relentlessly. Probe and search each object in a piece of art. Do not leave it,  do not course over it, as if it were understood, but instead follow it down until you see it in the mystery of its own specificity and strength. Giacometti's drawings and paintings show his bewilderment and persistence.  If he had not acknowledged his bewilderment, he would not have persisted.

Annie Dillard from The Writing Life
