“Transcendentalism has been called the inevitable flowering of the Puritan spirit. But Puritanism does not necessarily bear blossoms, and the fruit thereof is often gnarled and bitter. In New England, however, the soil was conserved by a bedrock of character, mellowed by two centuries of cultivation, and prepared by Unitarianism. New England Federalism checked the flow of sap, fearful lest it feed flowers of Jacobin red. There was just time for a gorgeous show of blossom and a harvest of wine-red fruit between this late frost and the early autumn blight of the Civil War.’’
