Terry Eagleton on Realism--

"A poet who managed to make his or her words 'become' the fruit they describe would be a greengrocer. No representation, one might say, without separation. Words are certainly as real as pineapples, but this is precisely the reason they cannot be pineapples. The most they can do is create what Henry James called the 'air of reality' of pineapples. In this sense, all realist art is a kind of con trick - a fact that is most obvious when the artist includes details that are redundant to the narrative (the precise tint and curve of a moustache, let us say) simply to signal: 'This is realism.' In such art, no waistcoat is colourless, no way of walking is without its idiosyncrasy, no visage without its memorable features. Realism is calculated contingency."
