David Cronenberg at Paris Review:
I woke up one morning recently to discover that I was a seventy-year-old man. Is this different from what happens to Gregor Samsa in The Metamorphosis? He wakes up to find that he’s become a near-human-sized beetle (probably of the scarab family, if his household’s charwoman is to be believed), and not a particularly robust specimen at that. Our reactions, mine and Gregor’s, are very similar. We are confused and bemused, and think that it’s a momentary delusion that will soon dissipate, leaving our lives to continue as they were. What could the source of these twin transformations possibly be? Certainly, you can see a birthday coming from many miles away, and it should not be a shock or a surprise when it happens. And as any well-meaning friend will tell you, seventy is just a number. What impact can that number really have on an actual, unique physical human life?
In the case of Gregor, a young traveling salesman spending a night at home in his family’s apartment in Prague, awakening into a strange, human/insect hybrid existence is, to say the obvious, a surprise he did not see coming, and the reaction of his household—mother, father, sister, maid, cook—is to recoil in benumbed horror, as one would expect, and not one member of his family feels compelled to console the creature by, for example, pointing out that a beetle is also a living thing, and turning into one might, for a mediocre human living a humdrum life, be an exhilarating and elevating experience, and so what’s the problem?
