He who seeks to approach his own buried past must conduct himself like a man digging. He must not be afraid to return again and again to the same matter; to scatter it as one scatters earth, to turn it over as one turns over soil. For the matter itself is only a deposit, a stratum, which yields only to the most meticulous examination what constitutes the real treasure hidden within the earth: the images, severed from all earlier associations, that stand --like precious fragments or torsos in a collector's gallery --in the prosaic rooms of our later understanding. Walter Benjamin
