Via the Guardian Book Blogs (and
coth), we have a consideration of life as being
stranger than science fiction and how SF tackles real life better than mainstream/realist literature. My point of view is mostly sympatico with Damien Walter's, but I have a problem with what seems to lie at the core of his argument:
"Realist fiction's unquestioning acceptance of modern life makes it difficult for the contemporary literary novel to find anything resembling the truth when it tackles issues of poverty, race, gender, politics, society or philosophy."
This suggests to me someone who is simply not widely read enough in contemporary literary novels on the issues he includes. I can name any number of novels that get close enough to "the truth" of their subject without any difficulty at all, although of course the measure of their success is just as subjective as it always has been for science fiction.
