We live in a society in which spurious realities are manufactured by the media, by governments, by big corporations, by religious groups, political groups. I ask, in my writing, 'What is real?' Because unceasingly we are bombarded with pseudo realities manufactured by very sophisticated people using very sophisticated electronic mechanisms.

I used to dig in the garden, and there isn't anything fantastic or ultradimensional about crab grass... unless you are a SF writer, in which case, pretty soon you're viewing crabgrass with suspicion. What are its real motives? And who sent it in the first place? The question I always found myself asking was, 'What is it, really?'
