Perl embraces the work of creative spirits as varied as Mozart, Michelangelo, Jane Austen, Henry James, Picasso, and Aretha Franklin. He contends that the essence of the arts is their ability to free us from fixed definitions and categories. Art is inherently uncategorizable—that's the key to its importance. Taking his stand with artists and thinkers ranging from W. H. Auden to Hannah Arendt, Perl defends works of art as adventuresome dialogues, simultaneously dispassionate and impassioned. He describes the fundamental sense of vocation—the engagement with the tools and traditions of a medium—that gives artists their purpose and focus. Whether we're experiencing a poem, a painting, or an opera, it's the interplay between authority and freedom—what Perl calls "the lifeblood of the arts"—that fuels the imaginative experience.
