Too seldom do we see so well credentialed an academician make so wide a leap from science to worldliness and romance, as Dr. Levin does in "Exclamations Part I "and "Part II." His work moves from Ben Franklin Bon Mot to lengthy Whitmanesque verbal tourism. And then in "Part II" on to social policy and social change. When questioned about the mix he says, "Truth is beauty and poetry is the ultimate verbal beauty."
