Elizabeth Costello by J. M. Coetzee

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 the 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. In such debates ideas do not and indeed cannot float free: they are tied to the speakers by whom they are enounced, and generated from the matrix of individual interests out of which their speakers act in the world—for instance, the son's concern that his mother not be treated as a Mickey Mouse post-colonial writer, or Wheatley's concern not to seem an old-fashioned absolutist.
