J.M.Coetzee, in "Elizabeth Costello":
"Realism has never been comfortable with ideas.
It could not be otherwise: realism is premised on the idea that ideas have no
autonomous existence, can exist only in things. So when it needs to debate
ideas, as here, realism is driven to invent situations – walks in countryside,
conversations – in which characters give voice to contending ideas and thereby
in a certain sense embody them. The notion of embodying turns out to be pivotal."
