A very important moment in the novel. That the novel itself might be a “draft”—an attempt to describe a subject that is too vast, too complex for one book—is another “postmodern” or contemporary-seeming idea. Melville clearly viewed his novelistic enterprise as Ishmael does, here—one that is impossible to fully complete. It also captures the idea of scientific and all knowledge, that it is some thing that is always growing, always revising and rewriting itself.
