Margaret Atwood on science fiction

There's a cool article on why we need science fiction in last Friday's Guardian Review, written by Atwood.

But it is still the human imagination, in all its diversity, that directs what we do with our tools. Literature is an uttering, or outering, of the human imagination. It lets the shadowy forms of thought and feeling - heaven, hell, monsters, angels and all - out into the light, where we can take a good look at them and perhaps come to a better understanding of who we are and what we want, and what the limits to those wants may be.

Well worth reading.
