“What happens if the writer is good is usually not that the work seems derivative or trivial but just the opposite: the work actually acquires depth and resonance from the echoes and chimes it sets up with prior texts, weight from the accumulated use of certain basic patterns and tendencies. Moreover, works are actually more comforting because we can recognize elements of them from our prior reading. I suspect that a wholly original work, one that owed nothing to previous writing, would so lack familiarity as to be quite unnerving to readers.”
