Mind Over Matters recently featured an interview with Prof. Gregory Sumner, author of Unstuck in Time: A Journey Through Kurt Vonnegut's Life and Novels.
Prof. Sumner clearly has great respect for the author and makes a good case for his continuing relevance. Unfortunately he's also eager to conspire with Vonnegut in distancing him from the dreaded label "science fiction." Vonnegut had no problem publishing in magazines like Galaxy Science Fiction and If (then being edited by Frederik Pohl), but the minute he hit the big time he did everything he could to renounce any connection to the genre. It's an understandable if not entirely admirable stance to take, and it's too bad Sumner didn't do more to set the record straight. The fact is that Vonnegut relied on sf tropes throughout his career, no matter how hard he and his biographer may try to deny it.
