G.K. Chesterton

Every work of art, divine or diabolic, has one indispensible mark-I mean, that the centre of it is simple, however much the fulfilment may be complicated. Thus, in Hamlet, let us say, the grotesqueness of the grave digger, the flowers of the mad girl, the fantastic finery of Osric, the pallor of the ghost and the grin of the skull are all oddities in a sort of tangled wreath round one plain tragic figure of a man in black.
