The first part of Nietzsche’s essay is a moving and occasionally hilarious paean to the virtues of forgetting, which he maintains is a prerequisite to human happiness, mental health, and action. Without dismissing the value of memory or history, he argues (much like Emerson and Thoreau) that we spend altogether too much of our energy laboring in the shadows of the past—under the stultifying weight of convention, precedent, received wisdom, and neurosis.
