“The relationship between science fiction and fantasy is difficult and topically important. At present, there’s a good deal of serious dissension among sf writers, especially in the Science Fiction Writers’ Association of America. Obviously many readers of sf are attracted to it because it performs the same operation as fantasy—it provides Recovery and Escape and wonder. But when they invoke the word ‘Science,’ and use an element of scientific knowledge (very variable, sometimes, in scope and accuracy) authors nowadays are more easily able to produce suspension of disbelief. The legendary laboratory ‘professor’ has replaced the wizard.”
Who do you think said this, in an interview in 1966?
