Imagine a type of writing so hard to define its very name means a trial, effort or attempt. An ancient form with an eye on the future, a genre poised between tradition and experiment. The essay wants above all to wander, but also to arrive at symmetry and wholeness; it nurses competing urges to integrity and disarray, perfection and fragmentation, confession and invention. How to write about essays and essayists while staying true to these contradictions? Essayismis a personal, critical and polemical book about the genre, its history and contemporary possibilities. It's an example of what it describes: an essay that is curious and digressive, exacting yet evasive, a form that would instruct, seduce and mystify in equal measure. Among the essayists to whom he pays tribute - from Virginia Woolf to Georges Perec, Joan Didion to Sir Thomas Browne - Brian Dillon discovers a path back into his own life as a reader, and out of melancholia to a new sense of writing as adventure.
