People often analogize the creative process to the reproductive one. They talk about the “labor pains” artists go through as they struggle to bring a novel piece of art into the world. They refer to “giving birth” to a new idea, painting, play or piece of music. There are, of course, exceptions to this referential rule. I’ve never heard it applied to, say, a mime routine or professional wrestling story arc, but it does seem, generally, to track to the world of art.
