Essayism is a book on fragments; of fragments extricable, but a whole indivisible. Fragments of essays, history, theory, anecdote and lesson.
It is, fascinatingly all at once, an exploration of the essay, a biography of the authors depression, and a handbook to its own creation. It so flawlessly weaves these threads together, calling upon digressions in a way so calculated and clever, that you might not even notice.
