Strangeness

"...I have tried to confront greatness directly: to ask what makes the
author and the works canonical. The answer, more often than not, has
turned out to be strangeness, a mode of originality that either cannot
be assimilated, or that so assimilates us that we cease to see it as
strange" -- Harold Bloom
