You have to distinguish between things that seemed odd when they were new but are now quite familiar, such as Ibsen and Wagner, and things that seemed crazy when they were new and seem crazy now, like 'Finnegans Wake' and Picasso.
Philip LarkinHeads in the Women's Ward On pillow after pillow lies The wild white hair and staring eyes; Jaws stand open; necks are stretched With every tendon sharply sketched; A bearded mouth talks silently To someone no one else can see. Sixty years ago they smiled At lover, husband, first-born child. Smiles are for youth. For old age come Death's terror and delirium.
